Single-Row, 4-Position Board-to-Board Receptacle
The 215297-4 is a 4-position, single-row receptacle from the AMPMODU HV-100 series, designed for board-to-board stacking with a 0.100-inch pitch footprint. It uses female square contacts with a gold mating finish — 31.5 microinches thick — which gives it decent corrosion resistance for repeated connection cycles in controlled environments.
Pitch and Position Fit for the BOM
At 4 positions on a single row, this receptacle fills a specific low-circuit-count slot on the board — common for power or signal jumpers where space is tight. The 0.100-inch pitch matches the standard AMPMODU HV-100 header line, so the mating half is a straightforward pick from the same series. The gold-on-mating, tin-on-post contact finish (31.5 microinches gold, 118.1 microinches tin on the post) balances signal integrity with solderability.
Cross-Shop: 1376775-2 vs 215297-4
Both share the 0.100-inch pitch, single row, through-hole kinked pins, and gold mating finish. The key difference: 1376775-2 uses 8.00 microinches of gold on the mating surface versus 31.5 microinches on 215297-4 — the thicker gold here buys more mating cycles before wear-through. If your BOM calls for exactly 4 positions, 215297-4 is the direct fit. For 5 positions, 1376775-2 is the sibling; the gold thickness difference matters if you expect frequent reconnections.
