Its 0.250\" (6.35 mm) pitch and triple-row layout pack 15 positions into a natural nylon housing with a 0.550\" (13.97 mm) insulation height — enough standoff to clear bulky components underneath on the PCB. The locking ramp fastening keeps the mated pair from backing loose under machine-mounted shock or transport vibration. The base product number is 641975; this specific variant is the 15-position, gold-plated, through-hole version in tray packaging. No pin-compatible cross-reference or successor is recorded — the Universal MATE-N-LOK family shares the same pitch and locking ramp, so a different position count or plating option would be a different base part. ## Mating with Universal MATE-N-LOK receptacles — what fits The 4-wall shrouding and board guide on the header align the receptacle during mating and protect the pins from damage if the connector is plugged in blind. No secondary lock is needed — the ramp alone holds the pair mated under normal vibration levels. ## Board layout notes — footprint and keep-out The through-hole solder tails are tin-plated, 0.155\" (3.94 mm) long — enough for a standard 0.062\" (1.6 mm) PCB with the tail protruding for a good solder fillet. Row spacing is 0.250\" (6.35 mm), matching the pitch, so the footprint is a 3×5 grid on 6.35 mm centers. The UL94 V-2 nylon housing is rated for flame retardance in equipment inside an enclosure — it will self-extinguish within the UL test window, but it's not V-0, so it's not suited for open-air or high-fire-risk installations without additional enclosure protection.","metaTitle":"641975-1 TE Connectivity Universal MATE-N-LOK Header 15 Pos","metaDescription":"641975-1 TE Connectivity AMP Connectors Universal MATE-N-LOK header, 15 pos, 3-row, 6.35mm pitch, 12A, 600VAC, gold mating contacts, through-hole, active.","metaKeywords":null},"attributes":{"series":"Universal MATE-N-LOK","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Style":"Board to Cable/Wire","title":"641975-1","Series":"Universal MATE-N-LOK","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER VERT 15POS 6.35MM","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"3","Pitch - Mating":"0.250\\\" (6.35mm)","Voltage Rating":"600VAC","Contact Material":"Phosphor Bronze","Insulation Color":"Natural","Insulation Height":"0.550\\\" (13.97mm)","Base Product Number":"641975","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"15","Row Spacing - Mating":"0.250\\\" (6.35mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.155\\\" (3.94mm)","Current Rating (Amps)":"12A","Operating Temperature":"-40°C ~ 105°C","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-2","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.46000","currency":"USD"},{"qty":78,"price":"$2.15718","currency":"USD"},{"qty":156,"price":"$1.97923","currency":"USD"},{"qty":468,"price":"$1.96814","currency":"USD"},{"qty":1014,"price":"$1.60119","currency":"USD"},{"qty":4914,"price":"$1.47888","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 641975-1 in this Pin Headers family?","answer":"No pin-compatible cross-reference or direct replacement is recorded.
