JBXFD2G04MSSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD2G04MSSDSMR is a 4-position circular connector plug manufactured by Souriau-Sunbank by Eaton, featuring male pins with solder cup termination. This connector is designed for industrial, instrumentation, medical, and telecommunications applications requiring shielded connections with push-pull fastening. The part is currently active in production with 765 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application-specific cable opening requirements necessitate different connector variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G04MSSDSMR is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector type: Plug with male pins
• Position count: 4 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Current rating: 15A minimum
• Insert material: PEEK
• Contact finish: Gold plating on mating surfaces

Secondary Compatibility Parameters:

• Shell material: Brass construction
• Flammability rating: UL94 V-0
• Regulatory compliance: ROHS3 and REACH Unaffected status

The three LEMO 2B series connectors (FGG.2B.304.CLAD52, FGG.2B.304.CLAD62, FGG.2B.304.CLAD72) meet all core compatibility parameters. These parts differ in cable opening specifications, which determine suitability for different cable gauges. Selection among substitute parts depends on the specific cable diameter requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

All three LEMO substitute parts (FGG.2B.304.CLAD52, FGG.2B.304.CLAD62, FGG.2B.304.CLAD72) are active products with ROHS3 compliance and REACH Unaffected status, meeting the same regulatory requirements as the primary JBXFD2G04MSSDSMR part.

Selection Criteria Based on Cable Specifications:

The primary differentiator among substitute parts is cable opening specification. Selection must be based on the cable diameter used in the application:

• FGG.2B.304.CLAD52: Cable opening 0.165" ~ 0.205" (4.20mm ~ 5.20mm) — suitable for smaller diameter cables
• FGG.2B.304.CLAD62: Cable opening 0.205" ~ 0.244" (5.20mm ~ 6.20mm) — suitable for medium diameter cables
• FGG.2B.304.CLAD72: Cable opening 0.244" ~ 0.283" (6.20mm ~ 7.20mm) — suitable for larger diameter cables

All substitute parts provide enhanced operating temperature range (-55°C ~ 250°C) compared to the main part (-40°C ~ 125°C) and improved ingress protection (IP50 versus IP40). Contact material for all LEMO substitutes is brass with 39.4µin (1.00µm) gold plating thickness.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.304.CLAD52, FGG.2B.304.CLAD62, and FGG.2B.304.CLAD72 be used interchangeably with JBXFD2G04MSSDSMR?

A: These parts are functionally equivalent in terms of connector type, pin count, termination method, and electrical ratings. However, they are not mechanically interchangeable due to different cable opening specifications. Selection must match the cable diameter of the application.

Q: What is the significance of cable opening specifications?

A: Cable opening defines the range of cable outer diameters that can be properly seated and secured within the connector backshell. Using a cable outside the specified range results in improper strain relief and potential connection failure.

Q: Are the LEMO substitute parts compatible with existing mating connectors designed for JBXFD2G04MSSDSMR?

A: Yes. All parts share identical connector type (plug, male pins), position count (4), fastening mechanism (push-pull), and shell size specifications. Mating compatibility is maintained across all parts.

Q: What are the differences in shell finish between the main part and substitutes?

A: JBXFD2G04MSSDSMR features chrome over nickel plating, while LEMO substitutes feature chrome plating. Both finishes provide corrosion resistance and are suitable for industrial applications.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant and REACH Unaffected. All parts carry UL94 V-0 flammability rating and use PEEK insert material.

Q: What is the advantage of the extended operating temperature range in LEMO substitutes?

A: LEMO parts operate from -55°C to 250°C, compared to -40°C to 125°C for the main part. This extended range provides flexibility for applications with more demanding thermal environments.

Q: How should cable opening selection be determined?

A: Measure the outer diameter of the cable to be used. Select the substitute part whose cable opening range encompasses this measurement. For example, a cable with 5.5mm outer diameter requires FGG.2B.304.CLAD62 (5.20mm ~ 6.20mm range).
