Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 1731090402 is determined by the following critical parameters:

• Connector Type: Receptacle with female sockets
• Number of Positions: 9-position configuration
• Number of Rows: 2-row layout
• Shell Size: Size 1 (DE, E designation)
• Connector Category: D-Sub, D-Shaped Connectors
• Termination Method: Crimp termination
• Mounting Style: Free hanging (in-line)

The substitute part Molex 1731090402 maintains compatibility through identical values across all these parameters. The transition from obsolete to active product status does not alter the physical or electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1731092064 serves as the active equivalent for the obsolete Molex 1731090402. Both components share identical connector specifications across all critical parameters: 9-position, 2-row D-Sub receptacle configuration with Size 1 shell, crimp termination, and matching electrical ratings.

Selection of the 1731092064 is appropriate for:

• Direct replacement in existing designs currently using 1731090402
• New designs requiring 9-position D-Sub receptacle functionality
• Applications requiring active product status and ongoing manufacturer support

The transition from 1731090402 to 1731092064 maintains full mechanical and electrical compatibility. Both parts are non-RoHS compliant, indicating equivalent material composition and processing methods.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1731092064 directly replace the 1731090402 in existing assemblies?

A: Yes. Both parts are 9-position, 2-row D-Sub receptacles with Size 1 shells, identical mounting styles, and matching electrical ratings. Physical and electrical interfaces are equivalent.

Q: What is the primary reason for substitution?

A: The 1731090402 is obsolete. The 1731092064 is the active equivalent from Molex's current product line, ensuring continued availability and manufacturer support.

Q: Are there differences in RoHS compliance between these parts?

A: The 1731090402 is explicitly RoHS non-compliant. RoHS status for the 1731092064 is not specified in the provided data. Verify RoHS requirements with Molex if compliance is a design constraint.

Q: Do these connectors support the same current and temperature ranges?

A: Yes. Both parts are rated for 5A current and operate across -55°C to 130°C temperature range.

Q: What termination method do these connectors use?

A: Both parts use crimp termination. Ensure wire gauge compatibility and proper crimping tools are used during assembly.
