For a drop-in alternative that avoids the tin-lead post finish, consider a current-production BergStik header with the same footprint and gold post plating. This header mates with any unshrouded BergStik receptacle or female socket strip on 0.100\" pitch, single row, 9 positions. The housing is thermoplastic rated UL94 V-0, and the insulation height is 0.100\" (2.54mm) above the board surface — the same as the pitch, which keeps the profile low for dense stacking.","metaTitle":"77311-802-09 Molex BergStik Header – 9-Pin 0.100\" Pitch","metaDescription":"Molex 77311-802-09 BergStik single-row 9-position 0.100\" pitch unshrouded header.
