The 0.156\" (3.96 mm) pitch is a common spacing for power connectors, giving you room to route thicker wire gauges without crowding the PCB. Right-angle through-hole termination keeps the mating axis parallel to the board, useful when the enclosure height is tight or the cable exits along the board edge. The shrouded 4-wall design protects the tab contacts from damage during handling and guides the mating receptacle into alignment, reducing the chance of bent pins. ## Locking ramp and board lock for secure assembly This is a practical safeguard in equipment that sees vibration or cable tugging—the connection stays put without relying on the friction fit alone. Board locks on the mounting posts anchor the header to the PCB during wave soldering, preventing the part from floating or skewing. After soldering, they add mechanical retention against the shear force from the cable harness. ## Temperature range and plating for industrial environments The tin-on-tin contact finish (both mating and post sides) is cost-effective for moderate mating-cycle duty. Current rating is listed as varying by wire gauge, which is standard for a tab-type header: the actual ampacity depends on the crimp terminal and the wire size used in the mating half. ## Sourcing and compliance status Available in bulk packaging.","metaTitle":"TE 178495-1 Header – 2 Pos, 3.96mm Right-Angle, Board Lock","metaDescription":"TE Connectivity 178495-1 Universal Power header, 2 positions, 0.156\" pitch, right-angle through-hole, shrouded 4-wall, locking ramp, board lock.","metaKeywords":null},"attributes":{"series":"Universal Power","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":"Universal Power","Package":"Bulk","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Tab","Contact Shape":"Rectangular","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.156\\\" (3.96mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.376\\\" (9.55mm)","Ingress Protection":"-","Base Product Number":"178495","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"2","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.150\\\" (3.81mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-30°C ~ 105°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":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.79000","currency":"USD"},{"qty":10,"price":"$0.75700","currency":"USD"},{"qty":100,"price":"$0.62390","currency":"USD"},{"qty":500,"price":"$0.56720","currency":"USD"},{"qty":1000,"price":"$0.49046","currency":"USD"},{"qty":5000,"price":"$0.42039","currency":"USD"},{"qty":10000,"price":"$0.41293","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7e54c9f8dfa2811147688eb82d4db065.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating part for 178495-1?","answer":"This header mates with a Universal Power series receptacle housing (e.g., 1-178128-2 or similar) that accepts the matching tab-type crimp terminals.
