The 4-wall shroud guides the mating receptacle squarely onto the pins, preventing bent contacts during blind or automated assembly. Rated 3 A per contact at 25°C, with the temperature rise limited by the UL94 V-0 thermoplastic housing. The 30 µinch gold plating on the mating face supports 500+ mating cycles — in a field-service cabinet where the connector is cycled quarterly, that is well over a century of service life at the contact interface. ## Operating range and deployment context The -65°C to 105°C operating temperature covers outdoor telecom cabinets, industrial control panels, and engine compartments — the phosphor bronze contacts and thermoplastic housing stay within their rated envelope across the band. The 0.135\" (3.43 mm) post length suits standard through-hole soldering on 1.6 mm boards. Tin-plated posts (100 µinch) provide a reliable solder joint; the gold mating finish handles the signal path without fretting corrosion over repeated insertions. ## Lifecycle and sourcing RoHS compliant per the manufacturer listing.","metaTitle":"5-103166-8 TE Connectivity AMPMODU Mod II Header, 20 Pos","metaDescription":"5-103166-8 TE Connectivity AMP Connectors AMPMODU Mod II header, 20 positions, 0.100\" (2.54 mm) pitch, shrouded 4-wall, right-angle, gold mating finish, 3 A","metaKeywords":null},"attributes":{"series":"AMPMODU Mod II","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Board or Cable","Series":"AMPMODU Mod II","Package":"Tray","Features":"-","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Detent Lock","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.400\\\" (10.16mm)","Ingress Protection":"-","Base Product Number":"103166","Insulation Material":"Thermoplastic","Number of Positions":"20","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.135\\\" (3.43mm)","Current Rating (Amps)":"3A","Operating Temperature":"-65°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"0.318\\\" (8.08mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1400","priceTiers":[{"qty":1,"price":"$6.14000","currency":"USD"},{"qty":10,"price":"$5.37900","currency":"USD"},{"qty":88,"price":"$5.12557","currency":"USD"},{"qty":440,"price":"$4.78764","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9e66d81b5cdb65385772d9ab07f66e0b.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/5-103166-8/alternatives.json"},"ai":{"faq":[{"question":"Does 5-103166-8 have a detent lock feature?","answer":"Yes, the fastening type is detent lock, which provides vibration-resistant retention without a secondary latch."},{"question":"What is the closest pin-compatible alternative to 5-103166-8?","answer":"The AMPMODU Mod II series includes other position counts and orientations, but a direct drop-in would require matching the 20 positions, 2.54 mm pitch, dual-row, right-angle, shrouded 4-wall, and detent lock — confirm the BOM position and mating half before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5-103166-8","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/5-103166-8 when reusing this data.
