Product details

3 Positions at 2.54mm Pitch — BOM Fit Check

Mating finish is 100.0µin tin-lead over copper alloy — a thick plating that handles occasional rework but not repeated mating cycles.

RoHS Non-Compliant — Plan for Exempt or Legacy BOMs

It fits legacy or exempt-equipment builds where lead-bearing finishes are still allowed. No direct OEM stock-holding claim.

Mating Half and Series Position

As an unshrouded header, it mates with any standard 2.54mm-pitch female socket housing — AMPMODU Mod II receptacles, or industry-standard 0.100" crimp-socket connectors.
