It uses a 0.100\" (2.54 mm) pitch on both the rows and the positions, matching the standard 0.1\" grid common on prototyping boards and legacy through-hole layouts. The right-angle orientation places the pin header parallel to the PCB surface, which suits board-edge cable routing in enclosures where vertical clearance is tight. Rated at 5 A per contact, the header carries enough current for signal-level and moderate power distribution — think sensor arrays, LED strips, or internal control wiring. The mating contacts carry 30.0 µ\" (0.76 µm) gold plating, which supports repeated mating cycles without contact fretting, while the solder tails are tin-plated for a reliable solder joint. The phosphor bronze contact material provides good spring retention over the connector's service life. The housing is rated UL94 V-0, so it meets the flame-retardancy requirement for equipment installed inside an enclosure. The push-pull fastening type means no locking latch — the retention comes from the friction fit of the pin-to-receptacle interface, which is typical for unshrouded headers in stationary board-to-board or wire-to-board applications where vibration is minimal. ## Position count and footprint At 46 positions, this is the full-populated dual-row member of the BERGSTIK® II 93939 series. Every position is loaded, so the 46 circuits match the BOM line count exactly — no depopulated positions to account for. The 0.100\" row spacing mirrors the pitch, giving a symmetrical 2.54 mm grid that routes cleanly to a standard 0.1\" header footprint.","metaTitle":"Amphenol 93939-146HLF BERGSTIK® II Header, 46 Pos","metaDescription":"Amphenol 93939-146HLF BERGSTIK® II unshrouded header, 46 positions, 2 rows, 0.100\" pitch, right-angle through-hole, gold-plated mating contacts rated 5 A.","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":"BERGSTIK® II","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"110V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.190\\\" (4.83mm)","Ingress Protection":"-","Base Product Number":"93939","Insulation Material":"-","Number of Positions":"46","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.160\\\" (4.06mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4235","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-146HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 93939-146HLF?","answer":"The pitch is 0.100\" (2.54 mm) on both the mating interface and the row spacing, matching the standard 0.1\" grid."},{"question":"What is the specification of 93939-146HLF?","answer":"It is a 46-position, dual-row, unshrouded header from the BERGSTIK® II series, with a 0.100\" pitch, right-angle through-hole mounting, gold-plated mating contacts rated 5 A, and a UL94 V-0 rated housing."},{"question":"What is the closest pin-compatible alternative to 93939-146HLF?","answer":"No official cross-reference or pin-compatible alternative is recorded for this order code.
