Rated 1250V, the connector supports applications where voltage isolation is a concern — telecom line cards, industrial control panels, and medical equipment inside an enclosure. ## 30 µinch Gold Mating Surface for Field-Service Duty The part is sourced multi-channel; stock availability varies, so an RFQ is the fastest path to a commitment. ## Mates with BergStik Headers — Pinout Check Required This receptacle is designed to mate with BergStik™ pin headers in the same 0.100\" pitch, single-row configuration. Insulation height is 0.325\" (8.25mm) — this sets the z-height budget when the mating header is on the opposite board. Confirm the stack height against your enclosure clearance before committing.","metaTitle":"66951-025LF Amphenol ICC (FCI) 25-Position 0.100\" Receptacle","metaDescription":"66951-025LF 25-position 0.100\" pitch board-to-board receptacle, Dubox/BergCon PV series, 30 µinch gold mating, 1250V, -65°C to 125°C, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"Dubox™, BergCon® PV™","Package":"Tube","Features":"-","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Female Socket","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Receptacle","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"1250V","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.325\\\" (8.25mm)","Ingress Protection":"-","Base Product Number":"66951","Insulation Material":"Polyester, Glass Filled","Number of Positions":"25","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.142\\\" (3.60mm)","Current Rating (Amps)":"-","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4301","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/639a2210187906c6ea18aa3d6f943b8d.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/66951-025LF/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 66951-025LF?","answer":"The 66951-025LF mates with a single-row BergStik™ pin header at 0.100\" pitch.
