Rated for automotive and general-purpose use, the header carries a UL94 V-0 glass-filled polyester insulation body, which holds up to the flame-rating requirements of equipment inside an enclosure. Solder termination with a 0.114\" (2.90mm) post length gives enough through-hole depth for standard 1.6mm PCBs. The post is tin-plated at 118.1 µinch (3.00 µm) — this is the solder-joint side, where tin ensures good wetting. ## Gold Mating Finish for Moderate-Cycle Reliability Fifteen microinches of gold is the entry-level thickness for applications that see occasional mating cycles — think field-service swaps or test-fixture connections — where the gold prevents oxide buildup on the pin surface. The square male pin shape with a 0.266\" (6.75mm) mating length provides a standard interface for C-Grid III crimp receptacles or IDC sockets.","metaTitle":"Molex 90122-0778 C-Grid III Header – 36 Pos, 0.100\" Pitch","metaDescription":"Molex 90122-0778 C-Grid III breakaway header, 36 circuits, 0.100\" (2.54mm) pitch, dual-row, right-angle, through-hole, gold mating finish.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Molex","Style":"Board to Board or Cable","Series":"C-Grid III 90122","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"Automotive, General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.242\\\" (6.14mm)","Ingress Protection":"-","Insulation Material":"Polyester, Glass Filled","Number of Positions":"36","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.114\\\" (2.90mm)","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"0.266\\\" (6.75mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"118.1µin (3.00µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.5800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ec96993a8c462a0ab98eeb415d8a3c4c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of Molex 90122-0778?","answer":"The mating pitch is 0.100\" (2.54mm), and the row spacing is also 0.100\" (2.54mm).
