This right-angle through-hole variant mates with matching receptacle housings and IDC sockets on the same pitch, making it a direct fit for legacy 2.54 mm grid layouts. The unshrouded push-pull design keeps the board footprint compact — no side walls to encroach on adjacent components — but also means there is no polarization keying, so orientation must be set at the board layout stage. Tin plating on both the mating surface and the solder tails (100.0 µin on the mating side) keeps per-unit cost low for moderate-cycle-count applications — think internal board stacks, test fixtures, or peripheral interconnects where the connector is mated a handful of times over its service life. The 5 A per-circuit rating at the 0.100\" pitch is typical for signal and light power duty; the limiting factor is the temperature rise through the unshrouded housing, not the contact itself. The UL94 V-0 rated black housing and phosphor bronze contacts suit equipment installed inside enclosures that require flammability compliance. Rated at 110 V, this header fits low-voltage signal and power distribution within a board assembly. ## Mounting and footprint Right-angle through-hole termination means the header sits flush against the board edge, with the pin row parallel to the PCB plane. The 0.120\" (3.05 mm) post length gives enough tail for a standard wave-solder process through a 0.062\" board. Mating pin length is 0.160\" (4.06 mm) — sufficient to engage a standard box-header or IDC receptacle without bottoming out. Row spacing matches the pitch at 0.100\" (2.54 mm), so the 28 positions occupy a 14-pin-per-row footprint. All positions are loaded — no optional empty slots to account for in the BOM. ## Sourcing and lifecycle The 93939-428HLF carries an Active lifecycle status from Amphenol — no end-of-life notice, no last-time-buy window. No official replacement or cross-reference is on record for this order code.","metaTitle":"Amphenol BERGSTIK II 93939-428HLF, 28-pos Header","metaDescription":"Amphenol BERGSTIK II 93939-428HLF 28-position dual-row male header, 0.100\" (2.54 mm) pitch, right-angle through-hole, tin-plated contacts rated 5 A, 110 V","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"93939-428HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","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)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.190\\\" (4.83mm)","Base Product Number":"93939","Number of Positions":"28","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.160\\\" (4.06mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5380","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/93939-428HLF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 93939-428HLF available via RFQ confirmation?","answer":"Contact the storefront with your BOM quantity for a same-day quote."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/93939-428HLF","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/93939-428HLF when reusing this data.
