Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for PLCC sockets is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Type: PLCC socket configuration
• Number of Positions: 32 (2 x 7, 2 x 9) pin grid
• Pitch - Mating: 0.050" (1.27mm)
• Contact Finish - Mating: Tin
• Mounting Type: Surface Mount
• Housing Material: Polyphenylene Sulfide (PPS)
• Termination: Solder

The Mill-Max Manufacturing Corp. part number 540-44-032-17-400000 satisfies all critical matching parameters and qualifies as a direct functional substitute. Both components feature identical mating pitch, pin count, contact finish specification, and housing material. The substitute part maintains the same closed frame construction and surface mount termination methodology.

Parameter Comparison

Engineering Selection Recommendations

The Mill-Max Manufacturing Corp. 540-44-032-17-400000 is the qualified substitute for the obsolete TE Connectivity 822475-2. Selection of this alternative is supported by the following factors:

Product Status: The substitute part maintains active product status, ensuring continued availability and manufacturer support. The original TE Connectivity component is obsolete, necessitating transition to an alternative source.

Compliance and Certifications: The Mill-Max substitute achieves ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment compared to the original part's undefined compliance posture. Both components maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Functional Equivalence: Critical mating interface parameters are identical between the two components, including pin count, mating pitch, contact finish specification, and housing material. These parameters ensure mechanical and electrical compatibility with existing PLCC device packages.

Post Pitch Consideration: The substitute part specifies 0.100" (2.54mm) post pitch compared to the original 0.050" (1.27mm) specification. This difference affects PCB footprint design and solder pad spacing. Design verification is required to confirm post pitch compatibility with existing printed circuit board layouts.

Frequently Asked Questions (FAQ)

Q: What determines whether a PLCC socket can substitute for the TE Connectivity 822475-2?

A: Substitution eligibility requires matching of the following parameters: PLCC type designation, 32-position pin count in 2 x 7, 2 x 9 configuration, 0.050" (1.27mm) mating pitch, tin contact finish on mating surfaces, surface mount mounting type, polyphenylene sulfide housing material, and solder termination method. Deviation in any of these parameters disqualifies a component from direct substitution.

Q: How does the post pitch difference affect component selection?

A: The Mill-Max substitute specifies 0.100" (2.54mm) post pitch versus the original 0.050" (1.27mm) specification. This difference directly impacts PCB footprint geometry, solder pad spacing, and via placement. Existing PCB designs developed for the TE Connectivity component require layout modification to accommodate the wider post pitch of the substitute part.

Q: Are there compatibility concerns with the contact material difference?

A: The original TE Connectivity component uses phosphor bronze contacts, while the Mill-Max substitute employs copper alloy contacts. Both materials are standard in PLCC socket applications and maintain equivalent electrical performance characteristics. The tin surface finish on both components ensures consistent solder wetting and joint reliability.

Q: What is the significance of the substitute part's active product status?

A: Active product status indicates ongoing manufacturer production, quality assurance, and technical support availability. The original TE Connectivity 822475-2 is obsolete, meaning the manufacturer no longer produces or supports this component. Transition to an active substitute ensures long-term procurement reliability and access to current manufacturing quality standards.

Q: Does the substitute part meet current regulatory requirements?

A: The Mill-Max 540-44-032-17-400000 achieves ROHS3 compliance and REACH unaffected status, satisfying current European Union regulatory frameworks. The original component's compliance status is undefined. Both components maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity classification.
