Its 0.150\" (3.81mm) mating pitch and 0.200\" (5.08mm) row spacing define the PCB footprint, while the right-angle orientation keeps the mated connector parallel to the board, saving vertical clearance in tight enclosures. ## Gold Mating Contacts and Industrial Temperature Range Mating contacts are gold-plated to 30.0µin (0.76µm) over a copper alloy base, supporting repeated mating cycles in corrosive or field-service environments. The post tails are tin-plated for solderability. Rated for 250V and an operating temperature range of -55°C to 105°C, the header suits general-purpose industrial applications.","metaTitle":"178308-3 TE Dynamic D-3100 Header 20 Pos 3.81mm R/A","metaDescription":"178308-3 TE Connectivity AMP Connectors Dynamic D-3100 header, 20 positions, 0.150\" pitch, right-angle, shrouded, gold mating contacts.","metaKeywords":null},"attributes":{"series":"Dynamic D-3100","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 Board or Cable","Series":"Dynamic D-3100","Package":"Bulk","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose, Industrial","Contact Type":"Tab","Contact Shape":"Rectangular","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Detent Lock","Number of Rows":"2","Pitch - Mating":"0.150\\\" (3.81mm)","Product Status":"Active","Voltage Rating":"250V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.568\\\" (14.43mm)","Ingress Protection":"-","Base Product Number":"178308","Insulation Material":"Thermoplastic, Polyester, Glass Filled","Number of Positions":"20","Row Spacing - Mating":"0.200\\\" (5.08mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.150\\\" (3.81mm)","Current Rating (Amps)":"-","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.5400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.54000","currency":"USD"},{"qty":10,"price":"$8.31500","currency":"USD"},{"qty":100,"price":"$7.39620","currency":"USD"},{"qty":500,"price":"$6.91478","currency":"USD"},{"qty":1000,"price":"$6.17078","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/79576a4f446979672270628dce9e8605.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of 178308-3?","answer":"The mating pitch is 0.150\" (3.81mm) with a row spacing of 0.200\" (5.08mm)."},{"question":"Is 178308-3 a right-angle or straight header?","answer":"It is a right-angle through-hole header, meaning the pins exit perpendicular to the PCB mounting plane."},{"question":"Does 178308-3 have a locking mechanism?","answer":"Yes, it features a detent lock for positive retention against vibration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/178308-3","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/178308-3 when reusing this data.
