Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 4-5176264-5 serves as the direct active equivalent for the obsolete 4-176264-5 connector header. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, row configuration, contact geometry, and operating temperature range.

The substitute part provides three significant advantages:

Product Status: The 4-5176264-5 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity. The original 4-176264-5 is classified as obsolete and subject to discontinuation.

Regulatory Compliance: The substitute part achieves ROHS3 compliance and REACH unaffected status, compared to the original part's RoHS non-compliant and REACH affected designations. This compliance improvement aligns with current regulatory requirements for electronic components in regulated markets.

Contact Finish Specification: The substitute part features tin post finish compared to the original tin-lead specification. This change reflects industry transition away from lead-containing materials while maintaining electrical and mechanical performance within the specified operating parameters.

All other parameters remain equivalent, confirming direct substitution capability for board-level integration and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 4-5176264-5 be used as a direct replacement for the 4-176264-5 in existing designs?

A: Yes. The substitute part maintains identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, row spacing, mounting method, and operating temperature range. Direct substitution is supported for both new designs and field service applications.

Q: What is the significance of the contact finish change from tin-lead to tin?
