Product details

Right-angle breakaway header, 40 positions

The 4-102975-0-20 is the 40-position member of TE's AMPMODU Mod II header line, an unshrouded breakaway style for board-to-board or cable connections. Dual-row 0.100" pitch, gold-plated mating contacts rated 3A, through-hole right-angle solder termination — the 0.318" mating length and 0.110" post length suit standard PCB stack-ups.

Production status — obsolete

TE Connectivity AMP Connectors lists the 4-102975-0-20 as Obsolete. A board spin is required for any functional replacement — the pitch and footprint differ across current-production AMPMODU series.
