Product details

32-Position PLCC Socket — Dual-Pitch Layout for Through-Hole Stability

The 54020-32030LF is a 32-position PLCC socket from Amphenol ICC (FCI) with a closed-frame design. Rated 1 A per contact with 20 mOhm contact resistance, the socket handles signal-level currents typical for PLCC-packaged microcontrollers, memory, and logic devices.

Board Layout Fit: Post Pitch and Termination Length

The 0.126" (3.20 mm) termination post length is standard for a 1.6 mm thick PCB; if the board is thicker than 2.4 mm, the post may not protrude enough for a reliable solder fillet. The 32-position grid is arranged as 2 x 7 and 2 x 9 — a common PLCC-32 footprint. Confirm the IC's pin 1 indicator aligns with the socket's chamfered corner before soldering.

Comparing the 54020-32030LF with a 44-Position Sibling

The 54020-44030LF is the same socket in a 44-position version (4 x 11 grid). All other specs match: 0.100" post pitch, 0.050" mating pitch, 1 A, tin contacts, PPS housing, UL94 V-0, through hole. The only decision point is the pin count — the 32-position 54020-32030LF fits a PLCC-32, the 44-position fits a PLCC-44.

RoHS compliant, no lead in the plating or housing. The tube packaging is standard for through-hole PLCC sockets — 20 to 30 pieces per tube depending on the factory pack quantity.

Frequently asked questions

Is the 54020-32030LF RoHS compliant?

Yes, the 54020-32030LF is RoHS compliant — no lead in the tin plating or the PPS housing.

Does the 54020-32030LF have a mating connector?

The 54020-32030LF is a PLCC socket — it mates directly with a PLCC-32 integrated circuit package. There is no separate mating connector; the socket's contacts wipe against the IC's leads.

What is a suitable replacement for the 54020-32030LF?

The 54020-44030LF is the same socket in 44 positions — not a pin-for-pin replacement. For a 32-position PLCC socket with a different termination, the 69802-132LF or 69802-032LF are surface-mount versions with thicker tin plating (150 µinch) and phosphor bronze contacts, but they require an SMT footprint instead of through-hole.
