The 0.126\" (3.20 mm) solder post length is typical for standard PCB thicknesses, allowing the socket to sit flush on the board after wave or hand soldering. ## Through-Hole Mounting and Termination This socket is a through-hole device with solder termination. The housing material is polyphenylene sulfide (PPS), which withstands the peak temperatures of lead-free wave soldering without deformation. The closed-frame design prevents solder wicking into the contact area during assembly. ## Contact Finish and Durability This thickness provides adequate wear resistance for moderate mating cycles—typical for production programming sockets or field-service IC replacement. Contact resistance is specified at 20 mOhm, which is consistent with tin-plated contacts in a production socket environment. No end-of-life notice or successor has been issued. ## Peer Comparison: 44-Position vs 32-Position The 54020-32030LF shares the same 0.100\" post pitch, 0.050\" mating pitch, tin plating, and through-hole mounting, but with 32 positions (2 x 7, 2 x 9 grid) — the 44-position version fits larger PLCC packages. For a surface-mount alternative, the 69802-044LF offers 44 positions with 0.050\" post pitch and 150 µinch tin plating, but requires an SMT reflow process rather than through-hole soldering.","metaTitle":"54020-44030LF PLCC Socket 44-Pin, 0.100\" Post Pitch","metaDescription":"Amphenol ICC (FCI) 54020-44030LF PLCC socket, 44 positions (4x11), 0.100\" post pitch, 0.050\" mating pitch, tin plating, through-hole, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","IC & Device Sockets"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Type":"PLCC","Series":"-","Package":"Tube","Features":"Closed Frame","Termination":"Solder","Pitch - Post":"0.100\\\" (2.54mm)","Mounting Type":"Through Hole","Pitch - Mating":"0.050\\\" (1.27mm)","Product Status":"Active","lifecycle_stage":"unknown","Housing Material":"Polyphenylene Sulfide (PPS)","Contact Resistance":"20mOhm","Base Product Number":"54020","Contact Finish - Post":"Tin","Current Rating (Amps)":"1 A","Operating Temperature":"-40°C~105°C","Contact Finish - Mating":"Tin","Contact Material - Post":"Copper Alloy","Termination Post Length":"0.126\\\" (3.20mm)","Contact Material - Mating":"Copper Alloy","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"100.0µin (2.54µm)","Number of Positions or Pins (Grid)":"44 (4 x 11)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.57000","currency":"USD"},{"qty":10,"price":"$2.33600","currency":"USD"},{"qty":25,"price":"$2.21200","currency":"USD"},{"qty":50,"price":"$2.16060","currency":"USD"},{"qty":100,"price":"$2.05780","currency":"USD"},{"qty":250,"price":"$1.80056","currency":"USD"},{"qty":500,"price":"$1.74910","currency":"USD"},{"qty":1000,"price":"$1.49189","currency":"USD"},{"qty":2500,"price":"$1.38900","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the post pitch and mounting type for the 54020-44030LF?","answer":"The post pitch is 0.100\" (2.54 mm) and the mounting type is through-hole with solder termination.
