JBXFD2G04MSSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD2G04MSSDSR 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 751 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 alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G04MSSDSR are identified from the LEMO 2B series based on the following substitution criteria:

Core Compatibility Parameters:

• Connector type: Plug with male pins
• Number of positions: 4
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding: Shielded configuration
• Current rating: 15A
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass with chrome finish
• Insert material: Polyetheretherketone (PEEK)
• Flammability rating: UL94 V-0
• Regulatory compliance: ROHS3 compliant, REACH unaffected

Differentiation Parameter: Cable opening specifications distinguish the four LEMO substitute parts. The JBXFD2G04MSSDSR does not specify a cable opening range, allowing compatibility with all four LEMO variants based on application cable diameter requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between the JBXFD2G04MSSDSR and LEMO FGG.2B.304 series variants is determined by cable opening requirements and operating temperature specifications.

For applications within the -40°C ~ 125°C temperature range: The JBXFD2G04MSSDSR remains the primary selection. LEMO substitutes operate across an extended temperature range (-55°C ~ 250°C) and are suitable for this application envelope.

For cable diameter accommodation: Select the appropriate LEMO variant based on cable opening specification:

• FGG.2B.304.CLAD52: 4.20mm ~ 5.20mm cable diameter
• FGG.2B.304.CLAD62: 5.20mm ~ 6.20mm cable diameter
• FGG.2B.304.CLAD72: 6.20mm ~ 7.20mm cable diameter
• FGG.2B.304.CLAZ: Unspecified cable opening range

All substitute parts maintain the 15A current rating, gold contact finish, shielded configuration, and push-pull fastening mechanism required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can LEMO FGG.2B.304 series connectors directly replace the JBXFD2G04MSSDSR?

A: Yes, the LEMO FGG.2B.304 series connectors are functionally equivalent based on core electrical and mechanical parameters: 4-position male plug configuration, solder cup termination, 15A current rating, gold contact finish, shielded design, and push-pull fastening. Selection of the specific LEMO variant depends on cable opening requirements.

Q: What is the primary difference between the JBXFD2G04MSSDSR and LEMO substitutes?

A: The primary differences are cable opening specifications and operating temperature range. The JBXFD2G04MSSDSR operates from -40°C to 125°C, while LEMO variants operate from -55°C to 250°C. LEMO variants specify cable opening ranges; the JBXFD2G04MSSDSR does not. Shell finish differs: JBXFD2G04MSSDSR uses chrome over nickel; LEMO variants use chrome only.

Q: How do I select the correct LEMO cable opening variant?

A: Measure the outer diameter of the cable to be terminated. Select the LEMO variant whose cable opening range encompasses this diameter: CLAD52 for 4.20-5.20mm, CLAD62 for 5.20-6.20mm, CLAD72 for 6.20-7.20mm. FGG.2B.304.CLAZ does not specify a cable opening range.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the JBXFD2G04MSSDSR.

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

A: The JBXFD2G04MSSDSR specifies a 1000V voltage rating. LEMO FGG.2B.304 series variants do not specify a voltage rating in the provided data. Verify voltage requirements with application specifications before substitution.

Q: Do the substitute parts maintain the same contact finish thickness?

A: No. The JBXFD2G04MSSDSR specifies 19.7µin (0.50µm) contact finish thickness. LEMO variants specify 39.4µin (1.00µm), which is thicker. Both provide gold plating on mating surfaces for corrosion resistance and electrical conductivity.

Q: What ingress protection rating should I expect from substitute parts?

A: The JBXFD2G04MSSDSR provides IP40 protection. LEMO FGG.2B.304 series variants provide IP50 dust protection, which exceeds the original specification and is suitable for more demanding environmental conditions.
