Engineering Selection Recommendations

The TE Connectivity 5745833-7 is the direct equivalent substitute for the obsolete 745833-7 backshell connector. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, cable exit angle, shielding configuration, and hardware specifications.

The primary distinction between these parts is regulatory and availability status. The 5745833-7 is classified as an active product with RoHS compliance certification and REACH affected status, whereas the 745833-7 is obsolete and RoHS non-compliant. The 5745833-7 offers superior long-term supply chain reliability with higher current inventory levels (1347 units versus 800 units).

For new designs and ongoing production requiring D-Sub 25 position shielded backshell connectors with 180° cable exit and Shell Size B compatibility, the 5745833-7 is the appropriate selection. The part maintains full mechanical and electrical interchangeability with the legacy 745833-7 while providing current regulatory compliance and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Is the 5745833-7 a direct replacement for the 745833-7?

A: Yes. The 5745833-7 is a direct equivalent substitute. Both parts share identical specifications for position count (25), cable exit angle (180°), shielding configuration, material composition, plating, and hardware specifications. The parts are mechanically and electrically interchangeable.

Q: What is the primary reason to transition from 745833-7 to 5745833-7?

A: The 745833-7 is classified as obsolete, while the 5745833-7 is an active product.
