Board guide features on the header help align the part during automated placement, reducing skew on the pick-and-place line. ## Mating Connector and Wire Termination This header mates with the Minitek® Pwr 3.0 receptacle housing (crimp-terminal style) — the 4-wall shroud and locking ramp are designed to engage the receptacle's outer latch, so the pair stays mated under cable strain. The gold flash on both mating and post contacts provides corrosion resistance and low contact resistance for moderate mating cycles — not rated for high-cycle reconnect duty like thicker gold, but sufficient for most field-service and panel interconnect applications. RoHS compliant. ## Comparing the 4-Position to the 8-Position Sibling The 10127721-082LF is the 8-position sibling in the same series — same 3.00 mm pitch, same dual-row layout, same shrouding and locking ramp. If the BOM calls for 8 circuits, the 10127721-082LF is a direct drop-in on the same footprint pattern — the board layout just extends the row by two more positions per side.","metaTitle":"10127721-042LF Amphenol ICC Minitek Pwr 3.0 Header 4 Pos 3mm","metaDescription":"10127721-042LF Amphenol ICC (FCI) Minitek® Pwr 3.0 header, 4 positions, 3.00 mm pitch, shrouded, locking ramp, gold flash, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Minitek® Pwr 3.0","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Cable/Wire","Series":"Minitek® Pwr 3.0","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.118\\\" (3.00mm)","Product Status":"Active","Voltage Rating":"600VAC/DC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.433\\\" (11.00mm)","Ingress Protection":"-","Base Product Number":"10127721","Insulation Material":"Thermoplastic","Number of Positions":"4","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Gold","Contact Length - Post":"0.126\\\" (3.20mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-40°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"Flash","Contact Finish Thickness - Mating":"Flash"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","priceTiers":[{"qty":1,"price":"$0.44000","currency":"USD"},{"qty":10,"price":"$0.38500","currency":"USD"},{"qty":300,"price":"$0.29017","currency":"USD"},{"qty":600,"price":"$0.27633","currency":"USD"},{"qty":1200,"price":"$0.22798","currency":"USD"},{"qty":5100,"price":"$0.20034","currency":"USD"},{"qty":10200,"price":"$0.18653","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9801841b405bfac4f4d88f4c475103f2.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/10127721-042LF/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/10127721-042LF","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/10127721-042LF when reusing this data.
