PLCC Socket, 44 Positions, Dual-Pitch Footprint
The 54020-44030LF is a 44-position PLCC socket in a 4 x 11 grid, designed to accept a JEDEC-standard PLCC package. 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.
