It uses through-hole solder termination with square male pins, push-pull fastening, and a black UL94 V-0 rated housing. This is a fully loaded header — all 38 positions are populated, so the BOM line matches the circuit count directly without unpopulated pins to track. With a 0.770\" (19.56mm) mating pin length and a 0.120\" (3.05mm) solder post, this header suits standard through-hole board thicknesses and typical mating receptacles in the BERGSTIK II family. ## 38 Positions vs 36 Positions — Same Pitch, One Row More The 87052-138HLF carries 38 positions against the 36 positions of the 87052-136HLF at the same 0.100\" (2.54mm) pitch and dual-row layout. The two extra positions add one more pin per row, extending the header length by 0.200\" (5.08mm) along the board edge. If the BOM calls for 36 circuits, the 87052-136HLF is the direct fit; for 38 circuits, this is the one.","metaTitle":"87052-138HLF BERGSTIK II Header, 38 Pos, 0.100\" Pitch, 5A","metaDescription":"Amphenol FCI 87052-138HLF BERGSTIK II unshrouded header, 38 positions, 0.100\" (2.54mm) pitch, through-hole, 5A, 30µin gold.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"87052-138HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"87052","Number of Positions":"38","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.990\\\" (25.15mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.770\\\" (19.56mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9706","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87052-138HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between 87052-138HLF and 87052-136HLF?","answer":"The 87052-138HLF has 38 positions while the 87052-136HLF has 36 positions, both at the same 0.100\" (2.54mm) pitch and dual-row layout.
