Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658676-1 is the direct equivalent substitute for the obsolete 748469-1. Both components share identical electrical and mechanical specifications across all connector parameters, including shell size, position count, contact configuration, and material composition.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 748469-1 is classified as obsolete and carries RoHS non-compliant and REACH Affected designations. The 1658676-1 is in active production status with ROHS3 Compliant and REACH Unaffected certifications.

For new designs, system upgrades, or ongoing procurement requirements, the 1658676-1 is the appropriate selection. This part maintains full form, fit, and function compatibility while providing current regulatory compliance and assured supply chain availability.

Frequently Asked Questions (FAQ)

Q: Are the 748469-1 and 1658676-1 mechanically interchangeable?

A: Yes. Both parts are identical in connector style, shell size, position count, row configuration, mounting type, and all physical dimensions. They are direct mechanical substitutes.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certifications. The 748469-1 is obsolete with RoHS non-compliant status. The 1658676-1 is in active production with ROHS3 Compliant and REACH Unaffected certifications. All electrical and mechanical specifications are identical.

Q: Can I use 1658676-1 in place of 748469-1 in existing systems?

A: Yes. The 1658676-1 is a direct substitute with identical form, fit, and function. No design modifications are required.

Q: What does "Contacts Not Included" mean?

A: Both the main part and substitute are housing assemblies only. Individual male contacts must be procured separately and inserted into the housing to complete the connector assembly.

Q: Why is the 748469-1 listed as obsolete?

A: The 748469-1 has been superseded by the 1658676-1 in the manufacturer's product line. The newer part number provides updated compliance certifications and active production support.
