No through-hole solder tails to hand-solder or wave-solder — the SMT pads are on the bottom side only. Mating contact finish is gold GXT at 15.0 µinch (0.38 µm) minimum — a hard gold alloy that handles 200+ mating cycles without exposing the phosphor bronze base metal. The tin-lead solder tails are a one-time joint — rework is possible but the post finish is not designed for multiple reflow cycles. ## Sourcing and Lifecycle — Obsolete Status The BERGSTIK series continues in production with other position counts and plating options, but this exact 34-position, SMT, gold GXT variant is discontinued. Contact base metal is phosphor bronze — good spring properties for the breakaway retention beams, though the primary retention comes from the SMT solder joint, not the contacts themselves.","metaTitle":"95278-801-34 BERGSTIK Header, 34-Pin, 0.100\" Pitch, SMT","metaDescription":"Amphenol ICC (FCI) 95278-801-34 BERGSTIK board-to-board header, 34 positions, 0.100\" (2.54 mm) pitch, SMT, unshrouded, gold GXT contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK®","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Obsolete","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"95278","Insulation Material":"Thermoplastic","Number of Positions":"34","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin-Lead","Contact Length - Post":"-","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold, GXT™","Contact Length - Mating":"0.232\\\" (5.90mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7130","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/aed765c5860c912bca7a744a204478c2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 95278-801-34?","answer":"This part is obsolete and not stocked in volume.
