The 3.20 mm post length (0.126\") is standard for through-hole soldering to a typical 1.6 mm PCB; the board guide feature helps align the header during wave solder assembly, preventing skew from the solder wave. No official cross-reference or pin-compatible alternative is listed from Molex. The 172310 series includes other position counts (2 to 10 circuits) in the same pitch and orientation, but a different position count means a different board footprint.","metaTitle":"Molex 1723103105 Ultra-Fit Header, 5 Pos, 3.50 mm","metaDescription":"Molex 1723103105 Ultra-Fit 172310 series header, 5 circuits, 3.50 mm pitch, through-hole right angle, tin plating, 600 V rating, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Ultra-Fit 172310","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"Ultra-Fit 172310","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"1","Pitch - Mating":"0.138\\\" (3.50mm)","Product Status":"Active","Voltage Rating":"600VAC/DC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.353\\\" (8.96mm)","Ingress Protection":"-","Base Product Number":"172310","Insulation Material":"Liquid Crystal Polymer (LCP)","Number of Positions":"5","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.126\\\" (3.20mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-40°C ~ 120°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"60.0µin (1.52µm)","Contact Finish Thickness - Mating":"60.0µin (1.52µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3900","priceTiers":[{"qty":1,"price":"$1.39000","currency":"USD"},{"qty":10,"price":"$1.15300","currency":"USD"},{"qty":90,"price":"$0.96089","currency":"USD"},{"qty":990,"price":"$0.76873","currency":"USD"},{"qty":4950,"price":"$0.67264","currency":"USD"},{"qty":10080,"price":"$0.63901","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a8e8c05ee8429c620704071e75cca157.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1723103105/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for Molex 1723103105?","answer":"The mating half is a Molex Ultra-Fit receptacle housing from the 172311 series, which accepts the matching crimp terminals.
