Engineering Selection Recommendations

The substitute part 5-534975-2 is the direct equivalent for the obsolete TE Connectivity 534975-2. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 534975-2 carries an obsolete product status, which restricts long-term availability and manufacturer support. The substitute part 5-534975-2 maintains active product status, ensuring continued availability and technical support from TE Connectivity.

Compliance & Certification: The substitute part 5-534975-2 is RoHS compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory requirements.

Functional Equivalence: All mechanical, electrical, and material specifications are identical between the main part and substitute. The connector maintains the same 120-position configuration, 0.100" pitch spacing, right-angle through-hole mounting, and gold-plated mating contacts. The post finish differs only in composition (tin versus tin-lead), which does not affect functional compatibility in standard solder joint applications.

Packaging: The substitute part is supplied in tube packaging, providing standardized handling and storage compared to the unspecified packaging of the main part.

Frequently Asked Questions (FAQ)

Q: Can the 5-534975-2 substitute directly replace the 534975-2 in existing designs?

A: Yes. The 5-534975-2 is mechanically and electrically equivalent to the 534975-2 across all critical parameters including position count, pitch spacing, mounting orientation, contact type, and finish specifications. Direct substitution is supported without design modification.

Q: What is the difference between the tin-lead post finish on the main part and the tin post finish on the substitute?

A: The main part features tin-lead post finish, while the substitute features tin post finish. Both finishes are suitable for standard solder joint applications. The tin finish on the substitute part aligns with RoHS compliance requirements, which restrict lead content in electronic components.

Q: Why is the main part classified as obsolete?

A: The 534975-2 is classified as obsolete by TE Connectivity, indicating that the manufacturer has discontinued active production and support. The substitute part 5-534975-2 remains in active production status, ensuring ongoing availability and manufacturer technical support.

Q: Are there any compatibility issues with the packaging difference?

A: No. The substitute part is supplied in tube packaging, which is a standard packaging format for connectors. Tube packaging provides equivalent protection and handling characteristics compared to alternative packaging methods. The connector itself maintains identical form, fit, and function.

Q: Does the RoHS compliance of the substitute part affect performance?

A: No. RoHS compliance on the 5-534975-2 reflects the removal of lead from the post finish composition. This change does not affect electrical performance, mechanical fit, or reliability in standard applications. RoHS compliance is a regulatory and environmental requirement that does not impact functional characteristics.

Q: What is the inventory status for the substitute part?

A: The substitute part 5-534975-2 has 1013 pieces in stock as new original inventory, providing immediate availability for procurement requirements.
