24-Position Dual-Row Board-to-Board Receptacle
The 1-215307-2 is a 24-position, dual-row board-to-board receptacle from the AMPMODU HV-100 series. The solder tails receive a 98.4µin (2.50µm) tin finish for reliable wave-solder wetting. In a low-vibration environment this is sufficient; for applications with shock or cable strain, a secondary retention method (board-mounting screws or a locking header) should be considered.
Through-Hole Termination and Housing Construction
Termination is through-hole with kinked pins — the kink provides a press-fit retention force during wave-solder, holding the connector in place before the solder solidifies. The housing is glass-filled polyester rated UL94 V-0 — the V-0 rating means the material stops burning within 10 seconds after a flame source is removed, with no flaming drips. It sets the z-height clearance needed above the PCB for the mated pair.
RoHS compliance is confirmed per the manufacturer's declaration. The part ships in tray packaging. No single-vendor lock — the AMPMODU HV-100 series is widely sourced through independent distribution.
Peer Comparison: 1-2823056-2 vs 1-215307-2
The closest functional second-source is the 1-2823056-2, also a dual-row 0.100" pitch receptacle but with 12 positions (half the circuit count of the 24-position 1-215307-2). The 1-2823056-2 uses tin-plated mating contacts and a forked contact shape, compared to the gold-plated square contacts on the 1-215307-2. For a 12-position board-to-board or board-to-cable application where gold plating is not required, the 1-2823056-2 is a cost-reduction candidate. For 24 positions or gold-plated mating-cycle reliability, the 1-215307-2 is the correct fit.
