It uses press-fit termination for solderless backplane assembly — the compliant pin compresses into a plated through-hole, giving a gas-tight joint that survives rework cycles without heat damage. The gold-plated female sockets carry 30.0µin of gold on the mating surface, good for repeated mating in high-reliability environments like telecom switches and data-center backplanes. ## What the 30V Rating Means for Your Board The 30V rating limits this connector to low-voltage signal and power distribution — think logic-level supplies, not mains or 48V telecom rails. On a backplane carrying 3.3V, 5V, or 12V busses, the 30V headroom is fine; just don't plan to route 48V or higher through these pins without a separate high-voltage connector in the system. The pitch and row density are the real constraints here — the 1.91mm spacing gives enough creepage for 30V but not for anything above. ## Press-Fit Termination — No Solder, No Problem This is the standard for high-density backplanes where reflow would stress the board or where rework is expected. The through-hole mounting type confirms it's a through-hole press-fit, not a surface-mount variant. On-site, if a pin gets damaged, you can extract and replace the connector without desoldering the whole backplane — a real advantage for field-service repairs. ## Mating Half and Field Replacement This receptacle mates with the Impact series male header (the 2057761-3 is the female side). The 9-row by 8-column grid means the mating header must have the same 72-position, 9-row, 0.075\" pitch layout. In the field, if you're replacing a damaged receptacle on a backplane, the press-fit pins let you pull the old one and press in a new one with a basic arbor press — no solder station required. Just confirm the board hole pattern matches the 0.075\" pitch before ordering.","metaTitle":"TE Impact 2057761-3 Receptacle, 72 Pos, 1.91mm Pitch","metaDescription":"TE Impact 2057761-3 receptacle, 72 positions, 9 rows, 0.075\" (1.91mm) pitch, press-fit, gold 30.0µin, UL94 V-0.
