20-Position Dual-Row Housing for AMPMODU Mod IV
The dual-row, 20-circuit layout suits harnesses where you need a compact, polarized connection for signal-level circuits — think control panels, industrial sensors, or internal appliance wiring. You order the female crimp terminals separately, then insert them after crimping to the wire.
The 3-87977-5 mates with AMPMODU Mod IV headers that use a 0.100" pitch, 2-row layout, and 0.025" square pins. For the crimp terminals, look for the AMPMODU Mod IV female socket contacts (TE part numbers in the AMPMODU IV series); the housing accepts the standard contact for 22-26 AWG wire. The dual-row body gives you 20 circuits in a roughly 1.0" x 0.5" footprint at the connector face.
It is RoHS compliant. No official cross-reference or second-source replacement is documented; sourcing is through the standard TE Connectivity distribution channel.
