It uses a right-angle through-hole mounting orientation, which places the mating face parallel to the PCB — useful for cable routing along the board edge in space-constrained enclosures. The header is fully shrouded with four walls, protecting the rectangular tab contacts from damage and providing polarization to prevent mis-mating with the cable-side receptacle. Integrated board locks anchor the header to the PCB during the solder process and resist shear forces from the cable harness during service — a detail that matters when the harness is routed through a moving assembly or near a service panel. ## Tin-Plated Contacts and Current Rating Both the mating and post contact finishes are tin, which is standard for cost-sensitive, moderate-cycle applications. The current rating is listed as 'Varies by Wire Gauge', meaning the ampacity is limited by the wire size crimped into the mating terminal, not by the header contact itself.","metaTitle":"9-1438789-2 TE Connectivity Multi-Lock Header, 38 Pos","metaDescription":"9-1438789-2 TE Connectivity AMP Connectors Multi-Lock header, 38 positions, right-angle through-hole, shrouded 4-wall, board lock, tin contacts.","metaKeywords":null},"attributes":{"series":"Multi-Lock","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"Multi-Lock","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"Automotive, General Purpose","Contact Type":"Tab","Contact Shape":"Rectangular","Mounting Type":"Through Hole, Right Angle","Connector Type":"-","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"-","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.815\\\" (20.70mm)","Ingress Protection":"-","Base Product Number":"1438789","Insulation Material":"Polycyclohexylenedimethylene Terephthalate (PCT)","Number of Positions":"38","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.134\\\" (3.40mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"-","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.0900","priceTiers":[{"qty":1,"price":"$6.09000","currency":"USD"},{"qty":32,"price":"$5.19406","currency":"USD"},{"qty":96,"price":"$5.08229","currency":"USD"},{"qty":448,"price":"$4.74717","currency":"USD"},{"qty":960,"price":"$4.43999","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a44f3a3bf179d9b8f6e88979efcfc6a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/9-1438789-2/alternatives.json"},"ai":{"faq":[{"question":"Is 9-1438789-2 RoHS compliant?","answer":"Yes, it is ROHS3 compliant."},{"question":"What is the current rating of 9-1438789-2?","answer":"The current rating varies by wire gauge — it depends on the wire size crimped into the mating terminal.
