The blue nylon insulation covers a 0.115\" to 0.170\" insulation diameter range and the overall length is 0.979\" (24.87 mm). ## Stud-size selection within PIDG Within the PIDG 14-16 AWG blue insulated spade line, the 52421-3 uses an 8-stud tongue (0.164\" inside opening) while the 52420-3 uses a 6-stud tongue (0.140\" opening) — the crimp length, wire range, and insulation are otherwise shared. The 52936-3 shares the 8-stud size but uses a wider outer-edge profile (0.375\" vs 0.281\") and a slightly different insulation diameter cap (0.182\" vs 0.170\").","metaTitle":"TE 52421-3 PIDG Spade Terminal, 14-16 AWG, #8 Stud, Blue","metaDescription":"TE Connectivity AMP Connectors PIDG spade terminal 52421-3: 14-16 AWG, #8 stud, tin-plated phosphor bronze, insulated blue nylon, serrated crimp, tape and reel.","metaKeywords":null},"attributes":{"series":"PIDG","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Wire-to-Wire Connectors","Spade Terminals"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Blue","Series":"PIDG","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Serrated Termination","Insulation":"Insulated","Wire Gauge":"14-16 AWG","Termination":"Crimp","Mounting Type":"Free Hanging (In-Line)","Stud/Tab Size":"8 Stud","Terminal Type":"Spring, Snap","Contact Finish":"Tin","Product Status":"Active","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Length - Overall":"0.979\\\" (24.87mm)","Base Product Number":"52421","Insulation Diameter":"0.115\\\" ~ 0.170\\\" (2.92mm ~ 4.32mm)","Width - Outer Edges":"0.281\\\" (7.14mm)","Length - Termination":"0.414\\\" (10.52mm)","Material - Insulation":"Polyamide (PA), Nylon","Tongue Inside Opening":"0.164\\\" (4.17mm)","Length - Ring Center to Termination":"0.270\\\" (6.86mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5800","priceTiers":[{"qty":1,"price":"$0.58000","currency":"USD"},{"qty":10,"price":"$0.54400","currency":"USD"},{"qty":25,"price":"$0.54200","currency":"USD"},{"qty":50,"price":"$0.52840","currency":"USD"},{"qty":100,"price":"$0.45320","currency":"USD"},{"qty":250,"price":"$0.40992","currency":"USD"},{"qty":500,"price":"$0.38714","currency":"USD"},{"qty":1000,"price":"$0.33931","currency":"USD"},{"qty":2500,"price":"$0.33476","currency":"USD"},{"qty":5000,"price":"$0.30060","currency":"USD"},{"qty":10000,"price":"$0.28184","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6f60d6e5fe11f22ec874f9721fb2a6d0.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/52421-3/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to 52421-3?","answer":"The 52420-3 is the same PIDG series, same wire range and insulation, but uses a #6 stud (0.140\" tongue opening) instead of #8 — the crimp tooling and wire preparation are identical."},{"question":"Will 52421-3 drop into a panel specified around 52420-3 without rewiring?","answer":"No — the stud size differs (#8 vs #6).
