JBXFD2G12MWSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD2G12MWSDSR is a 12-position circular connector plug with male pins manufactured by Souriau-Sunbank by Eaton. This connector is classified as an active product and features gold-plated mating contacts, shielded construction, and push-pull fastening. The part is designed for free-hanging in-line mounting applications requiring industrial, instrumentation, medical, and telecommunications connectivity. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component sourcing, inventory management, or design flexibility while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G12MWSDSR are identified based on strict alignment with the following critical parameters:

Matching Parameters (Required for Substitution):

• Connector Type: Plug, Male Pins
• Number of Positions: 12
• Fastening Type: Push-Pull
• Orientation: G
• Shielding: Shielded
• Current Rating: 7A
• Contact Finish - Mating: Gold
• Shell Material: Brass
• Insert Material: Polyetheretherketone (PEEK)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82 (both LEMO series 2B) satisfy all mandatory matching parameters. Differences in termination method (solder cup versus unspecified in main part), shell finish (chrome versus chrome over nickel), and operating temperature range represent design variations that do not preclude substitution when the application requirements align with the substitute specifications.

Parameter Comparison

Engineering Selection Recommendations

JBXFD2G12MWSDSR (Primary Part): Select this part when the application requires the specified voltage rating of 830V and operating temperature range of -40°C to 125°C. This part maintains active product status and full compliance with ROHS3 and REACH requirements.

FGG.2B.312.CLAD52 (Substitute - Solder Cup Termination, 4.20mm ~ 5.20mm Cable Opening): This substitute is functionally equivalent when solder cup termination is acceptable and cable diameter falls within 4.20mm to 5.20mm. The extended operating temperature range (-55°C to 250°C) and enhanced ingress protection (IP50) provide additional environmental capability. Contact finish thickness is doubled (39.4µin versus 19.7µin), offering increased durability in high-cycle mating applications.

FGG.2B.312.CLAD82 (Substitute - Solder Cup Termination, 7.20mm ~ 8.20mm Cable Opening): This substitute is functionally equivalent when solder cup termination is acceptable and cable diameter falls within 7.20mm to 8.20mm. Performance characteristics match FGG.2B.312.CLAD52 with identical operating temperature range, ingress protection rating, and contact finish thickness. Selection between CLAD52 and CLAD82 is determined solely by cable opening requirements.

All three parts maintain identical compliance certifications and are suitable for industrial, instrumentation, medical, and telecommunications applications where the specified electrical and mechanical parameters are met.

Frequently Asked Questions (FAQ)

Q: What determines whether FGG.2B.312.CLAD52 or FGG.2B.312.CLAD82 should be selected as a substitute?

A: The cable opening specification is the primary differentiator. CLAD52 accommodates cables with diameters of 4.20mm to 5.20mm, while CLAD82 accommodates cables with diameters of 7.20mm to 8.20mm. Select the substitute based on your cable diameter requirement.

Q: Are the LEMO FGG.2B.312 substitutes compatible with the JBXFD2G12MWSDSR in terms of mating?

A: Compatibility is determined by matching connector type (plug, male pins), number of positions (12), fastening type (push-pull), and orientation (G). All three parts meet these criteria. However, termination method differs: the main part uses unspecified termination while substitutes use solder cup. Verify that solder cup termination is acceptable for your application.

Q: What is the significance of the contact finish thickness difference?

A: The main part JBXFD2G12MWSDSR specifies 19.7µin (0.50µm) gold plating thickness, while both LEMO substitutes specify 39.4µin (1.00µm). The thicker plating on substitute parts provides enhanced resistance to wear and corrosion in high-cycle mating environments. This represents an improvement over the main part specification.

Q: Can the JBXFD2G12MWSDSR be used in applications requiring the -55°C to 250°C operating temperature range?

A: No. The JBXFD2G12MWSDSR is rated for -40°C to 125°C. If your application requires -55°C to 250°C operation, select FGG.2B.312.CLAD52 or FGG.2B.312.CLAD82.

Q: What is the difference between IP40 and IP50 ingress protection ratings?

A: IP40 provides protection against solid objects larger than 1mm but offers limited dust protection. IP50 provides complete dust protection. The LEMO substitutes offer enhanced environmental sealing with IP50 rating compared to the main part's IP40 rating.

Q: Are all three parts RoHS3 and REACH compliant?

A: Yes. JBXFD2G12MWSDSR, FGG.2B.312.CLAD52, and FGG.2B.312.CLAD82 are all ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for industrial and commercial applications.

Q: What is the voltage rating difference between the main part and substitutes?

A: The main part JBXFD2G12MWSDSR specifies 830V voltage rating. The LEMO substitutes do not specify a voltage rating in the provided data. Verify voltage requirements for your application before selecting a substitute.
