Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 822473-3 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Socket type classification (PLCC)
• Position count (32 positions in 2 x 7, 2 x 9 configuration)
• Through-hole mounting capability
• Closed frame design
• Solder termination method
• UL94 V-0 flammability rating
• Moisture sensitivity level (MSL 1)

The Mill-Max Manufacturing Corp. 940-44-032-24-000000 qualifies as a substitute based on matching these core functional parameters. Both components accommodate 32-position PLCC packages with through-hole solder termination and closed frame construction. Differences in mating pitch (0.050" vs. 0.100"), contact materials, and contact finish specifications represent design variations within the PLCC socket category that do not preclude functional substitution when application requirements permit.

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 822473-3 carries an obsolete product status, limiting long-term availability and support. The Mill-Max 940-44-032-24-000000 maintains active product status with documented inventory availability (4670 pieces in stock), ensuring procurement viability for current and future production requirements.

Compliance and Certification: The Mill-Max substitute achieves ROHS3 compliance, whereas the original TE Connectivity component is RoHS non-compliant. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, the Mill-Max alternative satisfies regulatory requirements. Both components maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, meeting standard reliability criteria.

Technical Specifications: The substitute component provides specified operating temperature range (-55°C to 125°C), current rating (1 A), and contact resistance (30mOhm), offering quantified performance parameters absent from the original part documentation. These specifications support design validation and thermal management analysis.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 940-44-032-24-000000 directly replace the TE Connectivity 822473-3 in existing designs?

A: Direct replacement requires verification of mating pitch compatibility. The TE Connectivity component specifies 0.050" (1.27mm) mating pitch, while the Mill-Max substitute operates at 0.100" (2.54mm) mating pitch. PCB layout and component package specifications must accommodate this difference. Both components share identical post pitch (0.100"), position count (32), and through-hole mounting configuration.

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

A: Contact material composition differs: the original uses phosphor bronze for both mating and post contacts, while the substitute employs beryllium copper for mating contacts and brass alloy for post contacts. Housing material also varies—thermoplastic versus polycyclohexylenedimethylene terephthalate (PCT) polyester. These material variations do not affect functional socket operation within specified electrical parameters.

Q: Does the RoHS compliance difference impact substitution decisions?

A: RoHS compliance status represents a regulatory and supply chain consideration rather than a functional performance factor. Applications subject to RoHS directives, EU regulations, or customer specifications mandating RoHS compliance must utilize the Mill-Max component. Non-regulated applications may accept either component based on availability and cost considerations.

Q: Are there packaging differences between these components?

A: The TE Connectivity 822473-3 packaging specification is not provided in available documentation. The Mill-Max 940-44-032-24-000000 is supplied in tube packaging. Packaging format may affect handling, storage, and assembly line integration requirements.

Q: What contact finish specifications should be considered for substitution?

A: The original component specifies tin-lead contact finish on both mating and post surfaces. The substitute provides tin finish without lead content. Tin-lead finishes offer different solderability and corrosion resistance characteristics compared to lead-free tin finishes. Application requirements regarding lead content and soldering process compatibility must be evaluated.

Q: How do the electrical performance specifications compare?

A: The Mill-Max substitute provides documented electrical specifications: 1 A current rating and 30mOhm contact resistance. The original TE Connectivity component does not include published electrical performance data. For applications requiring specified current handling or contact resistance limits, the Mill-Max component offers quantified performance validation.
