TE Connectivity AMP Connectors 822516-7 PLCC Socket Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 822516-7 is a 32-position PLCC socket designed for surface mount applications. This component features tin-plated phosphor bronze contacts with a 0.050" (1.27mm) mating pitch and closed frame construction. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 822516-7 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Type: PLCC Socket
• Number of Positions: 32 (2 x 7, 2 x 9)
• Pitch - Mating: 0.050" (1.27mm)
• Contact Finish - Mating: Tin
• Mounting Type: Surface Mount
• Features: Closed Frame
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Contact Material - Mating: Phosphor Bronze or Copper Alloy
• Contact Finish Thickness - Mating: 80.0µin to 160.0µin (2.03µm to 4.06µm)
• Housing Material: Thermoplastic, Polybutylene Terephthalate (PBT), or Glass Filled variants
• Operating Temperature: Extended ranges acceptable
• Product Status: Active preferred for obsolete parts

The identified substitute parts 8432-21B1-RK-TP (3M) and PLCC-32-AT-SMT (Adam Tech) satisfy all mandatory matching parameters and fall within allowable variations for contact materials and finish specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The 8432-21B1-RK-TP (3M) and PLCC-32-AT-SMT (Adam Tech) are both qualified substitutes for the obsolete 822516-7. Selection between these alternatives should be based on the following factors:

3M 8432-21B1-RK-TP:

• Active product status with established supply chain
• ROHS3 compliant and REACH unaffected
• Copper alloy contact material with 160.0µin tin finish thickness
• Operating temperature range: -40°C to 105°C
• Current rating: 1 A
• Packaging: Tube

Adam Tech PLCC-32-AT-SMT:

• Active product status with established supply chain
• ROHS3 compliant and REACH unaffected
• Phosphor bronze contact material matching original specification
• Extended operating temperature range: -55°C to 105°C
• Current rating: 1 A
• Contact resistance: 30mOhm
• Packaging: Tube

Both substitutes maintain the critical electrical and mechanical parameters of the original 822516-7. The choice between them depends on specific application requirements regarding operating temperature range and contact material preference. The Adam Tech part provides phosphor bronze contacts identical to the original specification, while the 3M part offers thicker tin plating and a narrower but industry-standard operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 8432-21B1-RK-TP or PLCC-32-AT-SMT be used as direct replacements for the 822516-7?

A: Yes. Both parts are qualified substitutes. They maintain identical pin counts (32 positions), mating pitch (0.050"), contact finish (tin), mounting type (surface mount), and frame configuration (closed frame). All three parts carry UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels.

Q: What is the difference between the contact materials in these parts?

A: The original 822516-7 and Adam Tech PLCC-32-AT-SMT use phosphor bronze contacts. The 3M 8432-21B1-RK-TP uses copper alloy contacts. Both materials are acceptable for PLCC socket applications and provide equivalent electrical performance in this application class.

Q: Are there differences in tin plating thickness among these parts?

A: Yes. The 822516-7 has 100.0µin (2.54µm) tin plating, the 3M part has 160.0µin (4.06µm), and the Adam Tech part has 80.0µin (2.03µm). All three thicknesses fall within acceptable ranges for PLCC socket contact durability and electrical performance.

Q: What are the operating temperature differences?

A: The 822516-7 does not specify an operating temperature range. The 3M 8432-21B1-RK-TP operates from -40°C to 105°C. The Adam Tech PLCC-32-AT-SMT operates from -55°C to 105°C, providing a wider low-temperature specification.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the 3M 8432-21B1-RK-TP and Adam Tech PLCC-32-AT-SMT are ROHS3 compliant and REACH unaffected. The original 822516-7 has undefined RoHS status and vendor-undefined REACH status.

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

A: Both substitute parts are supplied in tube packaging. The original 822516-7 packaging format is not specified in the available data.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts share identical footprints, pin assignments, and solder termination specifications. They are mechanically and electrically interchangeable within the constraints of the application's operating temperature requirements.

Q: What is the current rating for these PLCC sockets?

A: The 3M 8432-21B1-RK-TP and Adam Tech PLCC-32-AT-SMT both have a current rating of 1 A per contact. The original 822516-7 does not specify a current rating.
