4-Pin SMT Breakaway Header, 2.54 mm Pitch
Gold vs Tin Mating Finish — Why It Matters Here
Compared to the sibling 95293-401A04LF (same 4-position SMT header but with 78.7 µinch tin mating finish), this part carries 30 µinch GXT™ gold on the mating interface. The gold layer resists oxide buildup in humid or mildly corrosive environments and withstands more mating cycles — tin contacts are adequate for one-time or low-cycle assembly, but gold is the right call for connectors that see periodic disconnection in the field. The 3-position variant 95293-101-03LF is identical in all other specs (same pitch, gold finish, SMT) but carries one fewer circuit. If your BOM calls for exactly 4 positions, this is the part; the 3-position sibling is a functional drop-in for a 3-way board edge.
SMT Pick-and-Place Ready
Supplied on Tape & Reel or Cut Tape, with Pick and Place features — the flat top surface and vacuum-pick area allow standard nozzle handling during reflow assembly. Termination is solder-only — no press-fit or compliant-pin option. The tin-plated solder posts (78.7 µinch) wet well with standard SAC305 or leaded solder profiles.
RoHS Compliant per. Sourced through independent distribution; quantities confirmed at RFQ against your BOM quantity.
