PLCC-084-T-N Equivalent & Substitute Parts

Part Overview

The PLCC-084-T-N is an 84-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 functionally equivalent alternatives essential for ongoing production and maintenance applications. The socket accommodates 84 pins in a 4 × 21 grid configuration with 0.050" (1.27mm) mating pitch and operates across the industrial temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PLCC-084-T-N is determined by the following critical parameters:

• Pin Configuration: 84 positions in 4 × 21 grid arrangement
• Mating Pitch: 0.050" (1.27mm) spacing
• Mounting Technology: Surface mount only
• Contact Finish: Tin plating on mating contacts
• Socket Type: Closed frame PLCC socket
• Termination Method: Solder attachment
• Compliance Standards: UL94 V-0 flammability rating, ROHS3 compliance

The substitute part 8484-21B1-RK-TP from 3M meets these core electrical and mechanical requirements, enabling direct functional replacement in applications where the PLCC-084-T-N is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the PLCC-084-T-N and 8484-21B1-RK-TP are UL94 V-0 rated and ROHS3 compliant, meeting standard regulatory requirements for electronic component applications. The 8484-21B1-RK-TP is currently in active production status, whereas the PLCC-084-T-N is obsolete. Selection between these parts depends on application-specific temperature requirements: the PLCC-084-T-N supports extended low-temperature operation to -55°C, while the 8484-21B1-RK-TP operates from -40°C. For applications requiring the full -55°C lower temperature limit, the PLCC-084-T-N remains the specified choice. For standard industrial applications within the -40°C to 105°C range, the 8484-21B1-RK-TP provides an active, readily available alternative.

Frequently Asked Questions (FAQ)

Q: Can the 8484-21B1-RK-TP directly replace the PLCC-084-T-N in existing designs?

A: Direct replacement is possible for applications operating within the -40°C to 105°C temperature range. Both sockets share identical pin counts (84), pitch (0.050"), mounting type (surface mount), and contact finish (tin). Verify your application's temperature requirements against the operating ranges specified for each part.

Q: What are the key differences between these two PLCC sockets?

A: The primary differences are housing material (LCP versus glass-filled PBT), operating temperature range (-55°C to 125°C versus -40°C to 105°C), and product status (obsolete versus active). Both maintain equivalent electrical performance and compliance certifications within their respective operating ranges.

Q: Why is the PLCC-084-T-N classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 8484-21B1-RK-TP represents an active alternative from a different manufacturer, ensuring continued supply availability for new production and field replacements.

Q: Are there packaging differences between these parts?

A: The PLCC-084-T-N packaging is not specified in available documentation. The 8484-21B1-RK-TP is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PLCC-084-T-N and 8484-21B1-RK-TP are UL94 V-0 rated, ROHS3 compliant, and REACH unaffected, meeting standard regulatory requirements for industrial and commercial electronic applications.
