AI Summary	24-6337-9710 by Kester Solder: Leaded Rosin Mildly Activated (RMA) Wire Solder Sn63Pb37 (63/37) 20 AWG, 22 SWG Spool, 1 lb (454 g).	A premium option from Kester's 245 No-Clean cored wire series. It matches the original alloy, diameter, and packaging, but uses a low-residue No-Clean flux with a 2.2% core size (Core 58), which yields clean boards without needing post-solder cleaning. Premium No-Clean formulation from Kester (Series 245) Same Sn63Pb37 leaded alloy, 0.031" diameter, and 1 lb spool weight Extremely low-residue formulation for high cosmetic standards Lower flux core percentage (2.2% vs 3.3%) and a No-Clean formulation rather than traditional RMA.	An excellent direct-sibling alternative from the same Kester 285 RMA series, maintaining the same 0.031" diameter, 63/37 leaded alloy, and spool size. The only difference is a slightly lower flux core percentage of 2.2% (Core 58) compared to the original's 3.3% (Core 66). Direct sibling in the same Kester 285 RMA series Same Sn63Pb37 leaded alloy composition and 183°C melting point Same 0.031" (0.79mm) wire diameter and 1 lb spool form factor Slightly lower flux core percentage (2.2% vs 3.3%) may require slightly more focus on wetting during difficult solder joints.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
