Catalogue cross-references
Other part numbers catalogued against the same NSN as 441921-5 in DLA PUB LOG. A shared stock number is a cataloguing record. It is not a supersession, not a PMA approval, and not a statement that either part is eligible on your aircraft.

Catalog reference only; a CAGE association does not verify manufacturer or interchangeability.
PMA approval covers specific applications — confirm eligibility for your aircraft and operator approvals before ordering an alternate.
What 441921-5 is
441921-5 carries NSN 2915-01-542-9130, and the DLA catalogue names it "VALVE,FUEL SYSTEM". The buyer who requested it described it as an APU fuel control unit. Those two descriptions are not the same claim. A fuel system valve is a component class; an APU fuel control unit is a specific assembly on a specific system. The catalogue name is the one from a cataloguing authority, so this page uses it, and records what the buyer wrote rather than choosing the more specific of the two. If the distinction matters to your order, the NSN is the identifier to check. No manufacturer is verified in our records and no aircraft application is recorded, so this page states neither.

Condition guidance for 441921-5
Overhauled and serviceable are both published, and their medians are identical at $125,000. Overhauled rests on 10 quotes from 10 suppliers, serviceable on 4 from 4. Two conditions returning the same median is what our records show. We have no evidence about why, and the sample behind serviceable is small enough that the match may not survive more quotes.
13 quotes stated a lead time. The median was 0 days, the 75th percentile 11 days, and 7 quotes recorded a lead time of 0 days. 1 RFQ line from 1 RFQ, not flagged AOG. The supplier response was far heavier than the demand: 10 suppliers answered one request. One other reference number shares this NSN in the DLA PUB LOG. A shared NSN is an interchangeability record. It proves the numbers are catalogued against the same stock number. It does not prove either is approved on your aircraft, or that either is a PMA part.
Frequently asked
Our two sources disagree. The DLA catalogue record for NSN 2915-01-542-9130 says "VALVE,FUEL SYSTEM"; the buyer who requested it wrote "APU Fuel Control Unit". We publish both rather than picking one, and we use the catalogue name in the title because it comes from a cataloguing authority rather than from a request. Confirm against your own parts catalogue.
They do in our records: both medians are $125,000. We hold no evidence about why, and the serviceable figure rests on 4 quotes, which is our publication floor. Read the overhauled band as the better-evidenced of the two and ask suppliers what work each unit has had.
One reference number shares this NSN. That is a cataloguing relationship and nothing more. It is not a PMA approval, not a supersession, and not a statement that either part is eligible on your aircraft. Treat it as a lead to verify against your own approved data.
13 quotes stated a lead time, 7 recorded 0 days, and the 75th percentile was 11 days.
Prices are aggregated from quotes our sourcing desk requested from suppliers — never a single supplier’s price. Each is parsed automatically and spot-checked by a human when we quote it to a buyer; not every quote in this range has had that second look. Our methodology explains how we check them.
