Frequently Asked Questions (FAQ)

Q: Can the 1-747943-5 directly replace the 063389 in existing assemblies?

A: The 1-747943-5 is functionally equivalent for 9-position D-Sub applications. However, the 063389 is a backshell housing component, while the 1-747943-5 is a complete receptacle connector assembly. Integration into existing designs requires verification of mechanical mounting interfaces and connector body compatibility.

Q: What is the significance of the shell size designation?

A: Shell size E is the standard D-Sub shell size for 9-position connectors. Both the main part and substitute support this specification, ensuring compatibility with standard D-Sub connector bodies and mating plugs.

Q: Are there differences in material composition between the parts?

A: The 063389 uses zinc die-cast material, while the 1-747943-5 uses steel with tin plating. Both materials provide equivalent shielding effectiveness and environmental protection for D-Sub applications. The tin plating on the substitute provides corrosion resistance comparable to the original specification.

Q: What does the 4-40 jackscrew specification indicate?

A: The 4-40 designation refers to the mating screw size and thread pitch used to secure the connector backshell to the mating connector body. Both parts use identical 4-40 specifications, ensuring mechanical compatibility.

Q: Is the substitute suitable for high-temperature applications?

A: The 1-747943-5 operates across -55°C to 105°C, covering standard industrial temperature ranges. Applications requiring extended temperature operation beyond this range require evaluation of alternative connector solutions.

Q: What is the significance of RoHS compliance for both parts?

A: RoHS compliance indicates that both parts meet restrictions on hazardous substances, satisfying regulatory requirements for electronics manufacturing in regulated markets. The 063389 is ROHS3 compliant, while the 1-747943-5 is RoHS compliant, both meeting current environmental standards.

Q: How does the IDC termination of the substitute affect compatibility?

A: The 1-747943-5 supports IDC (Insulation Displacement Contact) and discrete wire termination. This provides flexibility for field assembly and repair applications while maintaining compatibility with standard D-Sub wiring practices.
