PLCC-032-T-N-TR Equivalent & Substitute Parts

Part Overview

The PLCC-032-T-N-TR is a 32-position PLCC socket manufactured by Samtec Inc., designed for surface mount applications with tin-plated beryllium copper contacts. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability. Substitute parts must maintain electrical and mechanical compatibility with the original specification while offering current market availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following critical parameters:

Socket Type & Position Count: All substitutes must be 32-position PLCC sockets
Mating Pitch: 0.050" (1.27mm) is mandatory for PLCC 32 compatibility
Mounting Configuration: Surface mount only
Frame Design: Closed frame construction required
Termination Method: Solder termination required
Contact Finish: Tin plating on mating contacts
Operating Temperature Range: Minimum -55°C to 125°C coverage
Flammability Rating: UL94 V-0 compliance required
RoHS Compliance: ROHS3 or equivalent compliance required

The three identified substitutes meet these core criteria. Variations in contact material, housing material, post pitch, and contact resistance are permissible within the PLCC 32 socket category, provided all mandatory parameters align.

Engineering Selection Recommendations

All three substitute parts are active products with current market availability and full RoHS compliance. Selection should be based on the following criteria:

69802-032LF (Amphenol ICC) maintains the full operating temperature range of -55°C to 125°C, matching the original specification exactly. This part is suitable for applications requiring the complete temperature envelope.

8432-21B1-RK-TR (3M) operates within -40°C to 105°C, representing a reduced temperature range. This part is appropriate for applications where the lower temperature limit of -40°C is acceptable and the upper limit of 105°C is sufficient.

PLCC-32-AT-SMT (Adam Tech) operates within -55°C to 105°C, providing the full lower temperature range but with a reduced upper limit of 105°C. This part is suitable for applications requiring extended low-temperature performance but not exceeding 105°C in operation.

Contact resistance values vary across substitutes (10mOhm original, 20mOhm Amphenol, 15mOhm 3M, 30mOhm Adam Tech). All values remain within acceptable ranges for PLCC socket applications. Housing materials and contact materials differ but do not affect electrical compatibility within the PLCC 32 socket standard.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitutes directly in place of the PLCC-032-T-N-TR?

A: Yes, all three substitutes are electrically and mechanically compatible with the original part. They share identical pin counts, mating pitch, contact finish, mounting type, and frame design. Compatibility is confirmed for standard PLCC 32 socket applications.

Q: What is the difference between the operating temperature ranges?

A: The original part and 69802-032LF both operate from -55°C to 125°C. The 8432-21B1-RK-TR operates from -40°C to 105°C, and the PLCC-32-AT-SMT operates from -55°C to 105°C. Select based on your application's temperature requirements.

Q: Why do contact resistance values differ between parts?

A: Contact resistance variations (10mOhm to 30mOhm) result from differences in contact material composition and manufacturing processes. All values are within acceptable ranges for PLCC socket applications and do not affect standard signal integrity or power delivery in typical use cases.

Q: Are all substitutes RoHS compliant?

A: Yes. The original part is ROHS3 compliant. The 69802-032LF is RoHS compliant, while 8432-21B1-RK-TR and PLCC-32-AT-SMT are both ROHS3 compliant. All meet current environmental regulations.

Q: What packaging formats are available?

A: The original PLCC-032-T-N-TR packaging is not specified. Substitutes are available in Tube (69802-032LF, PLCC-32-AT-SMT) and Tape & Reel (8432-21B1-RK-TR) formats. Confirm packaging requirements with your procurement process.

Q: Which substitute offers the best inventory availability?

A: The 8432-21B1-RK-TR (3M) offers the highest inventory level at 4774 pieces, followed by 69802-032LF (Amphenol ICC) at 3560 pieces and PLCC-32-AT-SMT (Adam Tech) at 2990 pieces.
