TE Connectivity AMP Connectors 1-822473-7 PLCC Socket Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-822473-7 is an 84-position PLCC socket designed for through-hole mounting applications. This component features tin-plated phosphor bronze contacts with a closed frame configuration and solder termination. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical and mechanical compatibility with the original specification while offering active product status and current availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-822473-7 are selected based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Type: PLCC Socket
• Number of Positions: 84 (4 x 21)
• Pitch - Mating: 0.050" (1.27mm)
• Pitch - Post: 0.100" (2.54mm)
• Contact Finish - Mating: Tin
• Mounting Type: Through Hole
• Termination: Solder
• Features: Closed Frame
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts match these critical parameters. Variations in contact material composition, housing material formulation, contact finish thickness, operating temperature range, and termination post length do not affect functional interchangeability for this socket category.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 8484-11B1-RK-TP (3M)

The 3M 8484-11B1-RK-TP is an active product with ROHS3 compliance and UL94 V-0 flammability rating. This part maintains all critical electrical and mechanical parameters required for direct substitution. The part is available in tube packaging with 2117 units in stock.

Secondary Substitute: PLCC-84-AT (Adam Tech)

The Adam Tech PLCC-84-AT is an active product with ROHS3 compliance and UL94 V-0 flammability rating. This part maintains all critical electrical and mechanical parameters required for direct substitution. The part is available in tube packaging with 1467 units in stock.

Both substitute parts are suitable for applications requiring the 1-822473-7 specification. Selection between alternatives may be based on procurement lead time, inventory availability, and supplier preference, as both parts satisfy the electrical and mechanical requirements of the original component.

Frequently Asked Questions (FAQ)

Q: Can the 8484-11B1-RK-TP or PLCC-84-AT be used as direct replacements for the 1-822473-7?

A: Yes. Both substitute parts maintain identical pin count (84 positions), mating pitch (0.050"), post pitch (0.100"), contact finish (tin), mounting type (through hole), termination method (solder), and frame configuration (closed). All three parts are UL94 V-0 rated and ROHS3 compliant.

Q: What are the differences between the substitute parts?

A: The primary differences are housing material composition and contact material specification. The 3M 8484-11B1-RK-TP uses copper alloy contacts with PBT glass-filled housing. The Adam Tech PLCC-84-AT uses phosphor bronze contacts (matching the original) with PBT glass-filled housing. Contact finish thickness varies slightly between parts but does not affect functional compatibility.

Q: Are there operating temperature differences between the parts?

A: The original 1-822473-7 does not specify an operating temperature range. The 3M 8484-11B1-RK-TP operates from -40°C to 105°C. The Adam Tech PLCC-84-AT operates from -55°C to 105°C. Both ranges are suitable for standard industrial and commercial applications.

Q: What is the significance of the housing material change from thermoplastic to PBT glass-filled?

A: PBT glass-filled material provides enhanced mechanical strength and thermal stability compared to standard thermoplastic. This material upgrade is common in active product lines and does not affect electrical performance or socket functionality.

Q: Are all three parts RoHS compliant?

A: Yes. The original 1-822473-7 and both substitute parts (8484-11B1-RK-TP and PLCC-84-AT) are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What packaging formats are available for the substitute parts?

A: The 3M 8484-11B1-RK-TP is supplied in tube packaging. The Adam Tech PLCC-84-AT is supplied in tube packaging. The original 1-822473-7 packaging format is not specified in the available data.
