PLCC-052-T-N-TR Equivalent & Substitute Parts

Part Overview

The PLCC-052-T-N-TR is a 52-position PLCC socket manufactured by Samtec Inc., designed for surface mount applications with tin-plated beryllium copper contacts. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing production support and design continuity. Substitute parts must maintain compatibility across critical electrical and mechanical parameters including pin count, pitch specifications, contact materials, and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PLCC-052-T-N-TR are qualified based on the following critical parameters:

• Pin Configuration: All substitutes must maintain 52 positions in a 4 x 13 grid arrangement
• Mating Pitch: 0.050" (1.27mm) pitch is mandatory for physical compatibility
• Contact Finish: Tin plating on mating contacts ensures solder compatibility
• Mounting Type: Surface mount configuration must be preserved
• Closed Frame Design: All qualified substitutes feature closed frame construction
• Flammability Rating: UL94 V-0 compliance is maintained across all options
• Moisture Sensitivity: MSL 1 rating ensures unlimited shelf life compatibility

The following parts meet these substitution criteria:

1. 8452-21B1-RK-TR (3M) - Active product with matching mating pitch and closed frame design
2. 940-44-052-17-400004 (Mill-Max Manufacturing Corp.) - Active product with matching pin configuration and surface mount termination

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified for direct replacement based on compliance and product status criteria:

8452-21B1-RK-TR (3M) is an active product with current manufacturing support. This part maintains RoHS compliance and carries a current rating specification of 1 A. The operating temperature range is -40°C ~ 105°C, which covers standard industrial applications but does not extend to the full -55°C ~ 125°C range of the original part.

940-44-052-17-400004 (Mill-Max Manufacturing Corp.) is an active product with ROHS3 compliance matching the original specification. This part maintains the same pin configuration and surface mount termination as the PLCC-052-T-N-TR.

Selection between these substitutes should be based on application-specific operating temperature requirements and supply chain availability. Both parts are available in tape and reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 8452-21B1-RK-TR be used in applications requiring -55°C operation?

A: The 8452-21B1-RK-TR has an operating temperature range of -40°C ~ 105°C. Applications requiring -55°C operation fall outside this specification and would require evaluation of the 940-44-052-17-400004 or alternative solutions.

Q: Are both substitute parts available in the same packaging format as the original?

A: The original PLCC-052-T-N-TR packaging specification is not provided. Both substitute parts are available in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly.

Q: What is the primary difference between the 8452-21B1-RK-TR and 940-44-052-17-400004?

A: Both parts share identical pin configuration (52 positions), mating pitch (0.050"), and contact finish (tin). The 8452-21B1-RK-TR specifies a current rating of 1 A and operates to 105°C maximum. The 940-44-052-17-400004 does not specify operating temperature limits in the provided data.

Q: Do all substitute parts maintain the same contact resistance specification?

A: The PLCC-052-T-N-TR specifies 10mOhm contact resistance. The 8452-21B1-RK-TR specifies 15mOhm. The 940-44-052-17-400004 does not provide contact resistance data. Contact resistance differences should be evaluated for applications with strict electrical performance requirements.

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes. All parts, including the original and both substitutes, carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements.
