The unshrouded design means there's no plastic guide to align the mating receptacle — the technician aligns pin-to-socket by eye. On a 38-position dual-row header, a slight angular misalignment during mating can bend the outer row pins. This header is best suited for controlled board-to-board or cable-to-board alignment where the mating half is fixture-guided or the harness is pre-aligned. ## Gold Flash on Mating, Tin on Tail — Why It Matters for Field Service The phosphor bronze contact spring retains its normal force over temperature swings, keeping contact resistance stable. ## Active Production — No End-of-Life Watch No LTB notice, no successor part number to cross-reference. For a BOM that needs this exact 38-position, 0.100\" pitch, unshrouded header, the supply chain is stable through independent distribution. The base product number 77313 covers the full BERGSTIK breakaway family; the -822-38LF suffix locks in the gold plating, 38 positions, and tin post finish. ## Dimensions and Pinout for the Harness Builder Row spacing is also 0.100\" (2.54 mm), so the 38 positions occupy a 19-position-per-row footprint — 18 positions on one row, 20 on the other, but all positions are loaded. In a high-vibration environment, consider a secondary retention method (board mount adhesive or a locking receptacle housing).","metaTitle":"77313-822-38LF BERGSTIK Header, 38 Pos, 2.54mm Pitch, 3A","metaDescription":"77313-822-38LF Amphenol ICC (FCI) BERGSTIK unshrouded breakaway header, 38 positions, 0.100\" pitch, 3A per contact, gold flash on mating, 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 or Cable","Series":"BERGSTIK®","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"77313","Insulation Material":"Thermoplastic","Number of Positions":"38","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~130°C","Mated Stacking Heights":"-","Overall Contact Length":"0.526\\\" (13.35mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.305\\\" (7.75mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7617","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/15efa251dc12bbd88801820e63936d0f.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/77313-822-38LF/alternatives.json"},"ai":{"faq":[{"question":"Is the 77313-822-38LF RoHS compliant?","answer":"The part number suffix 'LF' indicates lead-free (RoHS-compliant) plating.
