Gold vs Tin Mating Finish — 95157-440LF Alternative
The 95157-140LF: Tin is suitable for fewer mating cycles and lower-cost applications; gold supports higher cycle life and better corrosion resistance.

The 95157-140LF: Tin is suitable for fewer mating cycles and lower-cost applications; gold supports higher cycle life and better corrosion resistance.
The pinout is a standard dual-row 40-position header with all positions loaded. The mating contact length is 0.230" (5.84mm). Refer to the BERGSTIK® II series datasheet for the exact footprint and mating dimensions.
The 95157-440LF is a direct alternative with the same 40 positions, pitch, and SMD termination, but with a 100.0µin tin mating finish instead of gold. Choose the tin version for lower-cost, lower-cycle-count applications.
