Condition guidance for WE3881781-1
The only condition with a recorded quote history above our suppression threshold is serviceable (SV): 5 supplier quotes from 3 independent suppliers between 2026-07-07 and 2026-09-18. This sample is below the depth we require before publishing a price, so we show no low, median or high figure here. An overhauled (OH) quote exists but is withheld as a single quote from a single supplier.
Across the 5 usable quotes that stated a lead time, the median was 1 day, with a 25th percentile of 0 days and a 75th percentile of 30 days. 2 quotes recorded a lead time of 0 days, which reflects what was logged on those quotes, not stock on hand. The part was requested on 5 RFQ lines across 2 RFQs in the last 12 months, none marked AOG.

No manufacturer is verified for this part number in our evidence. We do not name one until a verified source confirms it.
We don't make stock claims. Of the quotes that recorded a lead time, two showed 0 days and the median across all 5 was 1 day, but that is a recorded duration, not an availability promise.
No other reference number shares its NSN, 2915-01-522-5781, in the DLA pub log, so we cannot name an alternate part number.
