The foil crimp area measures 1.125\" x 0.505\" (28.58mm x 12.83mm), which sets the foil width and thickness it can accept. Overall length is 1.625\" (41.28mm). These dimensions are the key fit check: the terminal must match the foil ribbon's cross-section and the available clearance in the assembly. ## Fit and cross-reference notes This terminal belongs to the Termi-Foil series, which includes other double-face terminals with different crimp areas and overall lengths. The base product number 5194 covers the family — the full 51943 suffix specifies the exact foil crimp area and finish. No direct pin-compatible alternative is listed; the closest match would be another Termi-Foil terminal with matching foil crimp dimensions, but the buyer must verify the crimp area and overall length against the BOM.","metaTitle":"51943 TE Connectivity Termi-Foil Double Face Tin Terminal –","metaDescription":"TE Connectivity 51943 Termi-Foil double face terminal, tin finish, foil crimp area 1.125\" x 0.505\" (28.58mm x 12.83mm), overall length 1.625\" (41.28mm).","metaKeywords":null},"attributes":{"series":"Termi-Foil","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["FFC / FPC & Ribbon Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"Termi-Foil","Package":"Bulk","Wire Gauge":"-","Terminal Type":"Double Face","Contact Finish":"Tin","Product Status":"Active","Foil Crimp Area":"1.125\\\" x 0.505\\\" (28.58mm x 12.83mm)","lifecycle_stage":"unknown","Contact Material":"Copper","Length - Overall":"1.625\\\" (41.28mm)","Base Product Number":"5194"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.93000","currency":"USD"},{"qty":10,"price":"$1.76700","currency":"USD"},{"qty":25,"price":"$1.71480","currency":"USD"},{"qty":50,"price":"$1.69740","currency":"USD"},{"qty":100,"price":"$1.57550","currency":"USD"},{"qty":250,"price":"$1.54936","currency":"USD"},{"qty":500,"price":"$1.41008","currency":"USD"},{"qty":1000,"price":"$1.26211","currency":"USD"},{"qty":2500,"price":"$1.16636","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the foil crimp area of the 51943 terminal?","answer":"The foil crimp area is 1.125\" x 0.505\" (28.58mm x 12.83mm).
