The white insulation color aids visual inspection of the mated connector. Rated at 600VAC, the header supports line-voltage applications within its temperature and current limits. ## Comparison with 4-1775099-7 (ATX series) The closest functional second-source is the 4-1775099-7 from the ATX series: 20 positions vs 22, 0.165\" (4.20mm) pitch vs 0.163\" (4.14mm), and 120.0µin (3.05µm) tin plating vs 150.0µin (3.81µm). The 4-1775099-7 uses square pins and is rated 9 A at 250VAC, while the 1-794078-0 uses circular pins and is rated 600VAC with current depending on wire gauge.","metaTitle":"1-794078-0 TE Connectivity AMP Connectors Mini-Universal","metaDescription":"1-794078-0 TE Connectivity AMP Connectors Mini-Universal MATE-N-LOK Header, 22 positions, 0.163\" (4.14mm) pitch, shrouded 4-wall, locking ramp, board lock, tin","metaKeywords":null},"attributes":{"series":"Mini-Universal MATE-N-LOK","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":"Mini-Universal MATE-N-LOK","Package":"Bulk","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.163\\\" (4.14mm)","Product Status":"Active","Voltage Rating":"600VAC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"White","Insulation Height":"0.531\\\" (13.50mm)","Ingress Protection":"-","Base Product Number":"794078","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"22","Row Spacing - Mating":"0.163\\\" (4.14mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.175\\\" (4.45mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-20°C ~ 85°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":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"150.0µin (3.81µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4300","priceTiers":[{"qty":1,"price":"$5.43000","currency":"USD"},{"qty":10,"price":"$4.75700","currency":"USD"},{"qty":100,"price":"$4.25910","currency":"USD"},{"qty":500,"price":"$3.96024","currency":"USD"},{"qty":1000,"price":"$3.53682","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/877131c53efca4cb5db7e122d4d9aa5e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-794078-0/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 1-794078-0?","answer":"The 1-794078-0 mates with Mini-Universal MATE-N-LOK receptacle housings that accept crimp terminals.
