Board-to-Board Fit: 26 Circuits at 0.100" Pitch
The 1-215307-3: This is a 26-position, dual-row receptacle from the AMPMODU HV-100 series, designed for board-to-board stacking.
Housing and Flame Rating
Peer Comparison: 1-2823056-2 and 1376775-2
Compared to the 1-2823056-2, this 1-215307-3 offers 26 positions versus 12, and a gold mating finish (31.5 µinch) versus tin — a meaningful upgrade for corrosion resistance and cycle life. The 1-2823056-2 uses a forked contact shape and surface-mount termination, so the footprint and assembly process differ. Against the 1376775-2 (5 positions, 8 µinch gold), the 1-215307-3 provides a higher circuit count and a thicker gold layer (31.5 µinch vs 8 µinch), which translates to more mating cycles before wear-through. Both are active receptacles in the same AMPMODU family, but the 1376775-2 carries a 3 A current rating and 250 VAC voltage rating not listed on this part.
