Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 822472-7 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Type: PLCC Socket
• Number of Positions: 84 (4 x 21)
• Pitch - Mating: 0.050" (1.27mm)
• Pitch - Post: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Features: Closed Frame
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these critical parameters. Variations in contact material composition, contact finish thickness, housing material formulation, and operating temperature ranges do not preclude functional substitution when these core parameters align. Contact finish composition (tin versus tin-lead) is compatible within this product category for PLCC socket applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 822472-7 carries obsolete status. All three substitute parts—3M 8484-21A1-RK-TP, Mill-Max 940-44-084-17-400000, and Adam Tech PLCC-84-AT-SMT—maintain active product status, ensuring availability for current and future production requirements.

Compliance and Certification: The original TE Connectivity part is RoHS non-compliant with vendor-undefined REACH status. All substitute parts achieve ROHS3 compliance and REACH Unaffected status, meeting contemporary regulatory requirements for electronic component procurement.

Functional Equivalence: All substitute parts satisfy the critical electrical and mechanical parameters required for PLCC socket applications. The 84-position configuration, 0.050" pitch specification, surface mount termination, closed frame design, and UL94 V-0 flammability rating are maintained across all alternatives.

Selection Basis: Component selection among the three active substitutes should be based on:

• Inventory availability requirements
• Specific operating temperature range needs
• Contact material performance specifications for the application
• Housing material compatibility with assembly processes
• Current rating and contact resistance specifications where applicable

Frequently Asked Questions (FAQ)

Q: Can the 3M 8484-21A1-RK-TP directly replace the TE Connectivity 822472-7?

A: Yes. Both components share identical PLCC socket configuration with 84 positions, 0.050" mating and post pitch, surface mount termination, closed frame design, and UL94 V-0 flammability rating. The contact finish difference (tin versus tin-lead) does not preclude functional substitution in PLCC socket applications.

Q: What is the primary reason for seeking substitutes for the TE Connectivity 822472-7?

A: The TE Connectivity 822472-7 is classified as obsolete. Substitute parts from 3M, Mill-Max, and Adam Tech maintain active product status, ensuring continued availability and supply chain reliability.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 3M 8484-21A1-RK-TP, Mill-Max 940-44-084-17-400000, and Adam Tech PLCC-84-AT-SMT all achieve ROHS3 compliance. The original TE Connectivity part is RoHS non-compliant.

Q: Do the substitute parts have different operating temperature ranges?

A: Yes. The 3M part operates from -40°C to 105°C, the Mill-Max part from -55°C to 125°C, and the Adam Tech part from -55°C to 105°C. The original TE Connectivity part does not specify an operating temperature range. Selection should account for application-specific thermal requirements.

Q: What contact materials are used in the substitute parts?

A: The 3M part uses copper alloy contacts, the Mill-Max part uses beryllium copper mating contacts with brass alloy post contacts, and the Adam Tech part uses phosphor bronze contacts (matching the original TE Connectivity material).

Q: Are all parts packaged identically?

A: All substitute parts are supplied in tube packaging. The original TE Connectivity part does not specify packaging format in the provided data.

Q: What is the current rating for the substitute parts?

A: The 3M 8484-21A1-RK-TP, Mill-Max 940-44-084-17-400000, and Adam Tech PLCC-84-AT-SMT all carry a 1 A current rating. The original TE Connectivity part does not specify current rating.

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

A: Yes. All substitute parts maintain identical footprint specifications with 0.050" pitch for both mating and post positions, enabling direct PCB layout compatibility.
