Engineering Selection Recommendations

For Direct Replacement (Plug Configuration):

Part number 1-747948-6 is the direct functional equivalent to the TE Connectivity Erni 183040. Both are D-Sub plug connectors with 25 positions, 2 rows, shell size 3 (DB, B), and IDC discrete wire termination. The 1-747948-6 is an active product from TE Connectivity AMP Connectors AMPLIMITE HDE-20 series, ensuring current manufacturing support and supply chain availability.

For Mating Pair Applications:

Part number 1-747947-5 provides the complementary receptacle configuration. When designing systems requiring both plug and receptacle connectors, the 1-747947-5 and 1-747948-6 form a compatible mating pair within the AMPLIMITE HDE-20 series.

Compliance and Certification:

Both substitute parts are RoHS Compliant and classified under ECCN EAR99. The obsolete status of the 183040 necessitates transition to these active alternatives to maintain regulatory compliance and ensure continued component availability for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the 1-747948-6 directly replace the TE Connectivity Erni 183040?

A: Yes. Both connectors share identical core specifications: 25-position D-Sub plug configuration, 2-row layout, shell size 3 (DB, B), and IDC discrete wire termination. The 1-747948-6 is the active equivalent from TE Connectivity AMP Connectors.

Q: What is the difference between 1-747947-5 and 1-747948-6?

A: The 1-747947-5 is a receptacle (female sockets) connector, while the 1-747948-6 is a plug (male pins) connector. Both share identical position count, row configuration, shell size, and termination type. Selection depends on whether your application requires a plug or receptacle interface.

Q: Are the substitute parts compatible with existing cable assemblies designed for the 183040?

A: Compatibility depends on the specific connector type used in the existing cable assembly. If the assembly uses a 25-position D-Sub plug with IDC termination, the 1-747948-6 is compatible. If the assembly uses a receptacle, the 1-747947-5 is the appropriate substitute.

Q: What is the wire gauge specification for these connectors?

A: The 1-747947-5 supports 26-30 AWG wire gauge, while the 1-747948-6 supports 22-26 AWG wire gauge. Verify your application's wire gauge requirements when selecting between these options.

Q: Are these connectors suitable for high-temperature applications?

A: Both substitute parts operate within the temperature range of -55°C to 105°C. Confirm this range meets your application requirements before selection.

Q: What is the voltage rating for these D-Sub connectors?

A: Both the 1-747947-5 and 1-747948-6 are rated for 250V, suitable for standard signal transmission applications.

Q: Are the substitute parts available in bulk packaging?

A: Yes. Both 1-747947-5 and 1-747948-6 are supplied in bulk packaging with current inventory availability (828 and 1163 pieces respectively).
