Condition guidance for 1558M31G07
Overhauled is the only condition with published pricing: 13 supplier quotes from 8 distinct vendors, $34,000 to $66,000, median $50,000, between August 7 and September 30, 2026. New-condition quotes exist but only 2 came from 1 supplier, short of the 3-quote threshold, so no new price can be published. Overhauled is the only band a buyer can currently benchmark against.
Across 14 quotes that stated a lead time, the pooled median was 6 days, with a 25th percentile of 0 days and a 75th percentile of 21 days. These cover all conditions together, not overhauled alone. 4 of those quotes recorded a 0-day lead time, which reflects what was logged on the quote, not confirmed stock. The part has been requested on 3 RFQ lines across 3 RFQs, all within the last 12 months, none marked AOG.

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.
