Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 1731070489 is determined by strict equivalence across the following critical parameters:

• Connector style and type (D-Sub, Combo, Receptacle, Female Sockets)
• Position count and configuration (13 positions: 7 + 6 Coax or Power)
• Shell size and layout (4 (DC, C) - 13W6)
• Mounting type (Panel Mount)
• Termination method (Solder Cup)
• Current rating (5A)
• Operating temperature range (-55°C ~ 130°C)
• Material specifications (Steel shell, Copper Alloy contacts, Gold finish, Polyester Glass Filled dielectric)
• Flammability rating (UL94 V-0)

The substitute part Molex 1731070330 meets all these criteria and is classified as active, making it a direct functional equivalent for the obsolete 1731070489.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1731070330 is the direct active equivalent for the obsolete Molex 1731070489. Both connectors share identical electrical and mechanical specifications across all critical parameters: 13-position D-Sub combo configuration, panel mount solder cup termination, 5A current rating, and -55°C to 130°C operating temperature range.

The primary distinction is product status: the 1731070489 is obsolete, while the 1731070330 is active and currently in production. The substitute part includes additional compliance documentation (ROHS3 Compliant, REACH Affected) and features tin plating on the steel shell, which provides enhanced corrosion resistance compared to the base steel finish of the original part.

For new designs or system replacements, the Molex 1731070330 should be specified. For legacy system maintenance where the original 1731070489 is required, the 1731070330 provides full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1731070330 be used as a direct replacement for the 1731070489 in existing assemblies?

A: Yes. Both connectors are mechanically and electrically identical across all functional parameters. The 1731070330 features identical pin configuration, shell size (4 (DC, C) - 13W6), mounting type (panel mount), and termination method (solder cup). No design modifications are required.

Q: What is the difference between the shell finishes on these two parts?

A: The 1731070489 has a steel shell with no specified finish. The 1731070330 has a steel shell with tin plating. Tin plating provides additional corrosion resistance and is standard for active production parts. Both finishes are compatible with the same mating connectors.

Q: Are there any compliance differences between these parts?

A: The 1731070330 includes documented RoHS3 compliance and REACH status, meeting current regulatory requirements. The 1731070489, being obsolete, does not have these specifications documented. Both parts meet the UL94 V-0 flammability rating.

Q: What is the current availability status of each part?

A: The 1731070489 is obsolete with 927 pieces in stock. The 1731070330 is active with 736 pieces in stock. For new procurement, the 1731070330 should be specified.

Q: Do these connectors require any special handling or installation considerations?

A: Both connectors use solder cup termination and are rated for 5A at -55°C to 130°C. Installation procedures are identical. Wire gauge compatibility is 20 AWG for both parts.
