The mating pitch is 0.050\" (1.27mm) while the through-hole post pitch is 0.100\" (2.54mm) — a common footprint for programming or production sockets that need to route the fine-pitch PLCC signals to a wider PCB layout. The 1-822473-2 is listed as Obsolete. The base product number 822473 may have other variants in the series (e.g., different plating or packaging), but no pin-compatible drop-in replacement is documented. Buyers should verify the 28-position grid and dual-pitch layout against any candidate substitute.","metaTitle":"1-822473-2 PLCC Socket, 28-Pin","metaDescription":"TE Connectivity 1-822473-2 PLCC socket, 28 positions (4x7 grid), 0.100\" post pitch, 0.050\" mating pitch, tin-plated contacts, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Type":"PLCC","Series":"-","Package":"Box","Features":"Closed Frame","Termination":"Solder","Pitch - Post":"0.100\\\" (2.54mm)","Mounting Type":"Through Hole","Pitch - Mating":"0.050\\\" (1.27mm)","Product Status":"Obsolete","lifecycle_stage":"unknown","Housing Material":"Thermoplastic","Contact Resistance":"-","Base Product Number":"822473","Contact Finish - Post":"Tin","Operating Temperature":"-","Contact Finish - Mating":"Tin","Contact Material - Post":"Phosphor Bronze","Termination Post Length":"-","Contact Material - Mating":"Phosphor Bronze","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"80.0µin (2.03µm)","Contact Finish Thickness - Mating":"80.0µin (2.03µm)","Number of Positions or Pins (Grid)":"28 (4 x 7)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-822473-2/alternatives.json"},"ai":{"faq":[{"question":"Is 1-822473-2 obsolete?","answer":"Yes, the 1-822473-2 is listed as Obsolete.
