3M 10240-55G3VC D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The 3M 10240-55G3VC is a 40-position Mini D Ribbon (MDR) receptacle connector designed for panel mount, through-hole, right-angle solder termination applications. This connector features an outer shroud contact design with board lock and shielding for reliable signal integrity in ribbon cable assemblies.

The 10240-55G3VC carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10240-55G3VC is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle with outer shroud contacts
• Position Count & Row Configuration: 40 positions, 2 rows
• Mounting & Termination: Panel mount, through-hole, right-angle solder
• Mechanical Interface: Housing/Shell (M2.6) flange feature
• Electrical Properties: Gold contact finish at 30.0µin (0.76µm) thickness
• Functional Features: Board lock and shielding

The substitute part 10240-55G3PC maintains identical electrical and mechanical specifications across all these parameters, differing only in product status (active vs. obsolete) and packaging configuration (tray vs. bulk).

Parameter Comparison

Engineering Selection Recommendations

The 10240-55G3PC is the direct functional equivalent to the obsolete 10240-55G3VC. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility.

Product Status Consideration: The 10240-55G3PC carries active product status, providing assured long-term availability and supply chain support compared to the obsolete 10240-55G3VC.

Compliance Advantage: The 10240-55G3PC is RoHS compliant, whereas the 10240-55G3VC is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the 10240-55G3PC is the appropriate selection.

Packaging Difference: The 10240-55G3PC is supplied in tray packaging, while the 10240-55G3VC uses bulk packaging. Packaging selection depends on inventory management and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Are the 10240-55G3VC and 10240-55G3PC electrically and mechanically interchangeable?

A: Yes. Both parts are 40-position, 2-row Mini D Ribbon receptacles with identical contact finish, flange dimensions, mounting configuration, and termination method. They are direct substitutes for circuit board and panel mount applications.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance status (non-compliant vs. compliant), and packaging format (bulk vs. tray). The electrical and mechanical specifications are identical.

Q: Why should I select the 10240-55G3PC over the 10240-55G3VC?

A: The 10240-55G3PC is recommended because it is an active product with assured availability, carries RoHS compliance certification, and maintains full functional equivalence. The 10240-55G3VC is obsolete and may face supply constraints.

Q: Does packaging affect connector performance or compatibility?

A: No. Packaging (tray vs. bulk) affects only storage, handling, and inventory management. It does not impact electrical performance, mechanical fit, or functional compatibility in the application.

Q: Can I use the 10240-55G3PC as a direct replacement in existing designs specified for the 10240-55G3VC?

A: Yes. The 10240-55G3PC is a direct replacement. No design modifications are required. Verify that your application requirements align with RoHS compliance if applicable to your industry or customer specifications.
