Mechanical and Electrical Equivalence: Both parts maintain identical specifications across all functional parameters: 15-position configuration, shell size A compatibility, 180° cable exit, shielded design, and identical material and plating specifications. Direct substitution is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 5745172-2 be used as a direct replacement for the 745172-2 in existing designs?

A: Yes. The 5745172-2 maintains complete mechanical and electrical equivalence to the 745172-2 across all functional parameters, including position count, shell size compatibility, cable exit angle, shielding configuration, and material specifications. Direct substitution is supported without design changes.

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

A: The 5745172-2 is the active production equivalent of the obsolete 745172-2. The substitute part includes improved regulatory compliance (ROHS3 compliant versus non-compliant) and maintains current manufacturing availability. Functional specifications remain identical.

Q: Are there packaging differences between the 745172-2 and 5745172-2?

A: The 745172-2 is listed without specified packaging, while the 5745172-2 is supplied in bulk packaging. Both parts are identical in form, fit, and function for D-Sub backshell applications.

Q: What D-Sub connector sizes are compatible with these backshell parts?

A: Both the 745172-2 and 5745172-2 are compatible with 15-position D-Sub connectors and HD26-position D-Sub connectors using shell size A. The 180° cable exit and round cable type specifications apply to both compatible connector sizes.

Q: Is the 5745172-2 suitable for applications requiring RoHS compliance?

A: Yes. The 5745172-2 is ROHS3 compliant, making it appropriate for applications and markets with RoHS compliance requirements. The original 745172-2 is non-compliant and should not be used in RoHS-regulated applications.

Q: What hardware specifications apply to these backshell connectors?

A: Both parts feature mating screws with 4-40 specifications. The 5745172-2 includes additional strain relief hardware as part of its assembly specification, providing enhanced mechanical support compared to the original part.
