Board-to-Board or Cable Interconnect with 38 Circuits
Mating Header and Footprint Fit
The bottom or top entry design means the same part works for board-to-board stacking or cable-to-board harnesses. If your header has gold posts, the mixed-metal interface is fine; if the header is tin, the gold-to-tin junction still works within the 2 A rating, though mating-cycle life shifts to the tin side.
No official successor or pin-compatible cross-reference is listed by TE. For a direct replacement, stick with the AMPMODU Mod IV series and verify the 38-position, 0.100" pitch, dual-row footprint.
