5962-99A1104NZE is the kind of part number that invites expensive assumptions. Search results may associate it with onsemi or show an inventory listing, yet the public record does not provide enough information to treat it like an ordinary commercial integrated circuit. The controlled acquisition identity is the complete Defense Logistics Agency (DLA) number, and each field carries a qualification or configuration meaning.

The safest purchasing approach is therefore evidence first. Confirm the governing drawing, current revision, approved source and manufacturing flow before comparing offers. Do not fill gaps in the public data with a guessed function, package, temperature range, radiation rating or commercial equivalent.

What Is Confirmed About 5962-99A1104NZE?

The strongest current public evidence is DLA’s Single Source Part Data for QML-38535, dated March 31, 2026. It lists 5962-99A1104NZE under Federal Supply Class 5962 and MIL-PRF-38535. The report shows “Not Stock Listed” in the National Stock Number field.

Those facts establish a procurement context, but they do not establish the device’s electrical function or imply that DLA has inventory. They also do not validate a seller’s quantity, date code or chain of custody.

Publicly verifiable item	What it means for a buyer	What it does not prove
Listed in DLA’s March 31, 2026 single-source report	The full PIN is recognized within the QML-38535 qualification context	Current commercial availability or seller authorization
Federal Supply Class 5962	The item is an electronic microcircuit	Circuit function, voltage, speed or pinout
MIL-PRF-38535	Acquisition involves qualified microcircuit manufacturing and assurance requirements	That any loose lot offered online conforms
NSN shown as “Not Stock Listed”	The report does not provide a National Stock Number for this PIN	Obsolescence, cancellation or lack of demand

SupplyICs currently associates the number with onsemi in the 5962-99A1104NZE product record. That catalog association is useful for routing an inquiry, but the purchase decision still needs the controlled records described below.

Read the SMD Number Without Guessing

The DLA Standard Microcircuit Drawing program uses a structured Part or Identifying Number (PIN). MIL-HDBK-103 explains the sequence as the federal stock class, Radiation Hardness Assurance (RHA) designator, drawing designator, device type, device class, case outline and lead finish.

For 5962-99A1104NZE, that structure can be read as follows:

Field	Code	Controlled meaning
Federal stock class	5962	Electronic microcircuits
RHA position	-	No RHA level is designated by the PIN
Drawing designator	99A11	A custom-product SMD drawing number
Device type	04	The fourth device type defined by drawing 99A11
Device class	N	Class N plastic-encapsulated microcircuit
Case outline	Z	Package definition that must be read from the applicable drawing
Lead finish	E	Lead-finish definition controlled by the applicable drawing and specification

The letter inside 99A11 matters. MIL-HDBK-103 explains that a single alpha character in the unique portion of a one-part, one-part-number SMD drawing identifies a custom product. That is a warning against substituting a familiar commercial part based on a partial cross-reference.

The dash after 5962 is equally important. It occupies the RHA position and does not designate an RHA level. Military use, QML processing and radiation hardness are separate claims; one cannot be inferred from the others.

Why the DLA Single-Source Listing Matters

DLA describes its single-source list as a request for possible additional sources. The agency states that certification and qualification requirements are set by the general specification and applicable device documentation, and that a source must be approved by the responsible DLA qualification office.

For a buyer, “single source” is therefore a qualification signal rather than a normal distributor stock label. It can affect schedule, source approval, deviation authority and the evidence required with a quote. An open-market listing does not become an approved source merely because the seller repeats the DLA number.

The current QML-38535 qualification page should be checked at the time of purchase because qualification status and approved flows can change. As of September 3, 2026, that page identifies Revision M of MIL-PRF-38535 as the effective general specification and separately lists Revision N as a second initial draft. A draft should not be substituted for the contractually invoked revision.

Confirm the Manufacturer and QML Scope

onsemi publishes a MIL-PRF-38535 certification page for its qualified sites. A DLA qualification expansion letter to onsemi also records Class Q and Class N certification for the Pocatello, Idaho operation and explains that products made on certified technology flows may be listed on QML-38535.

Manufacturer-level certification is necessary context, but it is not lot-level proof. Confirm all of the following for the offered material:

• The approved source and CAGE code applicable to the full 5962-99A1104NZE PIN.
• The design, wafer fabrication, assembly and test flow authorized for this device.
• The drawing number and revision invoked by the purchase order.
• The manufacturer’s certificate of conformance and any required screening or quality-conformance records.
• The relationship between markings on the device, labels, packing documents and the approved source entry.

If the approved-source record is unclear, resolve it with the program’s component engineer or the DLA office shown on the qualification page before accepting the quote. A general onsemi certificate cannot close a device-specific gap by itself.

Build the Acquisition Data Package Before Quoting

An exact-part inquiry should request enough information to compare offers without losing the original requirement. A practical request package includes:

1. Full PIN: 5962-99A1104NZE, without shortened punctuation or suffixes.
2. Required SMD drawing and revision, plus any source-control drawing or program addendum.
3. Quantity, required delivery date and whether split date or lot codes are permitted.
4. Approved manufacturer, CAGE code and QML manufacturing-flow requirements.
5. Certificate-of-conformance, acquisition-traceability and screening-data requirements.
6. Required case outline, lead finish, marking, packing and moisture-handling provisions.
7. Inspection and test plan, including whether destructive physical analysis needs a retained sample.
8. Written authority for substitutions, deviations, rework or repackaging.

Keep the product requirement separate from the seller’s commercial description. DLA’s Standard Microcircuit Cross-Reference expressly cautions that a vendor part number should not be used for acquisition because it may not satisfy the standard PIN’s performance requirements.

Inspect a Class N Lot Without Losing Traceability

MIL-PRF-38535M defines Class N as a plastic-encapsulated microcircuit (PEM) at class level B. It requires applicable qualification, screening and technology-conformance or quality-conformance inspection, while also placing responsibility on the user to assess whether the product suits the application.

Incoming inspection should preserve that qualified identity. Start with unopened packing, outer labels, seals, quantity and document reconciliation. Photograph each level before opening it. Compare the device marking format, logo, country or site codes, lot identifiers and date codes across the lot. Any mixed marking style or unexplained date-code spread should be quarantined until reconciled.

Inspection depth should follow program risk and purchase-order requirements. Low-power optical inspection can document surface condition and marking consistency. X-ray can compare internal construction and lead-frame geometry within a homogeneous lot. For a PEM, acoustic microscopy may be relevant when the acceptance plan addresses delamination, voiding or package integrity. Electrical testing must use the limits and conditions in the controlled device documentation; a generic continuity check cannot demonstrate SMD conformance.

For independent-channel material, align the inspection plan with the broader date-code and traceability controls. Do not remove or discard labels, reels, trays or bags until the lot has been accepted and its evidence retained.

Control Packaging, Storage, and Lot Identity

Class N identifies a plastic package, so packaging and storage records are part of configuration control rather than an afterthought. The applicable drawing, manufacturer packing information and purchase order should decide the moisture-sensitivity level, dry-pack requirements, humidity indicator, desiccant, floor-life controls and bake conditions. Do not assign an MSL from the NZE suffix alone.

Require the inner and outer packaging to reconcile to the same manufacturer, full PIN, lot/date code and quantity. If material must be repacked, record who performed the work, when it occurred, the electrostatic-discharge controls used and how original labels were preserved. Keep each manufacturing lot segregated unless the purchase order expressly permits consolidation.

Long storage also needs a program decision on solderability, terminal finish condition, packing integrity and retest. The letter E is a controlled lead-finish code, but its exact material and acceptance criteria must be taken from the governing drawing rather than a generic SMD table.

Apply Strict Replacement and Cross-Reference Rules

There is no responsible drop-in replacement decision without the 99A11 drawing. A proposed alternative must be compared against device type 04, device class N, case outline Z, lead finish E and every electrical, environmental, screening and marking requirement invoked by the program.

Treat a commercial number as a traceability clue, not as the procurement identity. A valid engineering comparison should address at least:

• Circuit function, pin assignment and logic or analog behavior.
• Absolute maximum ratings and every guaranteed operating limit.
• Package dimensions, coplanarity, terminal finish and assembly profile.
• Temperature range, screening, burn-in and quality-conformance inspection.
• Change notification, manufacturing-flow control and qualification status.
• System-level qualification and contractual approval for the change.

Channel choice also changes the evidence available. onsemi recommends buying directly or through its authorized distributor network and states that it cannot guarantee material obtained from unauthorized resellers. When an authorized route cannot meet the requirement, use a documented independent-channel process rather than assuming the channel distinction disappears; the onsemi sourcing comparison explains the different controls.

Programs in defense and aerospace should keep the full PIN, controlled drawing and approval authority visible through quoting, receiving, inspection and release.
