Engineering Selection Recommendations

For New Production and Design Implementation:

The 5749205-1 is the appropriate selection for new designs and production applications. This part maintains full functional and mechanical equivalence to the 749205-1 while offering Active product status and ROHS3 compliance. The ROHS3 compliance status aligns with current regulatory requirements for electronic components in most jurisdictions and supply chain frameworks.

For Field Replacement and Legacy System Support:

The 749205-1 remains functionally equivalent to the 5749205-1 for field replacement applications in existing systems where RoHS compliance is not a contractual or regulatory requirement. Both parts are identical in mechanical fit, electrical performance, and physical dimensions within the AMPLIMITE .050 III connector series.

Compliance Considerations:

The transition from 749205-1 (RoHS non-compliant) to 5749205-1 (ROHS3 compliant) reflects updated manufacturing standards. Organizations subject to RoHS directives or customer specifications requiring RoHS compliance must specify the 5749205-1. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Frequently Asked Questions (FAQ)

Q: Are the 749205-1 and 5749205-1 mechanically interchangeable?

A: Yes. Both parts are 80 Position Two Piece Backshell Connectors with identical mechanical dimensions, cable exit angles (75°), shielding configuration, and mounting hardware. They are direct mechanical substitutes within the AMPLIMITE .050 III series.

Q: What is the primary difference between these two parts?

A: The 749205-1 is Obsolete and RoHS non-compliant, while the 5749205-1 is Active and ROHS3 compliant. All functional and mechanical specifications are identical.

Q: Can I use the 5749205-1 as a replacement for the 749205-1 in existing assemblies?
