JBXFD2G05MSSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD2G05MSSDSMR is a 5-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 reliable signal and power transmission in demanding environments. The part maintains active product status with 933 units in current inventory stock.

Substitute parts become necessary when original inventory is unavailable, when alternative sourcing reduces lead times, or when design flexibility permits selection from qualified equivalent connectors meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G05MSSDSMR is determined by strict alignment of the following critical parameters:

Core Compatibility Criteria:

• Connector type: Plug with male pins
• Position count: 5 positions
• Termination method: Solder cup
• Fastening mechanism: Push-Pull
• Shielding configuration: Shielded design
• Current capacity: 14A minimum
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass construction
• Insert material: Polyetheretherketone (PEEK)
• Flammability rating: UL94 V-0
• Compliance: ROHS3 compliant, REACH unaffected

The three LEMO 2B series connectors (FGG.2B.305.CLAD62, FGG.2B.305.CLAD72, FGG.2B.305.CLAD92Z) satisfy all mandatory electrical and mechanical compatibility requirements. These parts differ only in cable opening dimensions, which accommodate different cable gauges while maintaining identical connector interface specifications.

Parameter Comparison

Engineering Selection Recommendations

All three LEMO substitute connectors maintain active product status and full compliance with ROHS3 and REACH regulatory requirements, matching the original JBXFD2G05MSSDSMR specification.

Selection Basis:

The LEMO 2B series connectors provide electrical and mechanical equivalence to the Souriau-Sunbank part across all critical interface parameters. Selection among the three LEMO variants depends solely on cable gauge compatibility:

• FGG.2B.305.CLAD62: Cable opening 5.20mm ~ 6.20mm
• FGG.2B.305.CLAD72: Cable opening 6.20mm ~ 7.20mm
• FGG.2B.305.CLAD92Z: Cable opening 8.20mm ~ 9.20mm

The LEMO connectors offer extended operating temperature range (-55°C ~ 250°C) compared to the original part (-40°C ~ 125°C) and enhanced ingress protection (IP50 versus IP40), providing additional environmental performance margin. Contact finish thickness on LEMO parts (39.4µin / 1.00µm) exceeds the original specification (19.7µin / 0.50µm), supporting extended service life in corrosive environments.

Frequently Asked Questions (FAQ)

Q: Can LEMO FGG.2B.305 series connectors directly replace the JBXFD2G05MSSDSMR in existing assemblies?

A: Yes, provided the cable gauge matches the selected variant's cable opening specification. The connector interface, pin configuration, electrical ratings, and termination method are identical. Physical mating and electrical performance are fully compatible.

Q: What is the primary difference between the three LEMO substitute options?

A: The three LEMO variants differ only in cable opening diameter range. FGG.2B.305.CLAD62 accommodates smaller cables (5.20mm ~ 6.20mm), CLAD72 accommodates medium cables (6.20mm ~ 7.20mm), and CLAD92Z accommodates larger cables (8.20mm ~ 9.20mm). Select the variant matching your cable gauge.

Q: Are there compliance or certification differences between the original and substitute parts?

A: No. Both the original JBXFD2G05MSSDSMR and all three LEMO substitutes carry identical ROHS3 compliance, REACH unaffected status, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification.

Q: How do operating temperature ranges compare?

A: The original part operates -40°C ~ 125°C. LEMO substitutes operate -55°C ~ 250°C, providing wider environmental capability. If your application operates within the original temperature range, both parts are functionally equivalent.

Q: What is the significance of the different shell finishes (Chrome over Nickel versus Chrome)?

A: Both finishes provide corrosion protection on brass shells. Chrome over nickel (original part) offers additional corrosion resistance in highly aggressive environments. Chrome finish (LEMO parts) is suitable for standard industrial, instrumentation, medical, and telecommunications applications. Select based on environmental exposure requirements.

Q: Do the substitute parts include backshell and boot adapter features?

A: The original JBXFD2G05MSSDSMR includes backshell and boot adapter features. LEMO FGG.2B.305 series include backshell only. Verify boot adapter requirements for your application before substitution.

Q: How do contact finish thicknesses affect connector performance?

A: The original part specifies 19.7µin (0.50µm) gold plating. LEMO substitutes provide 39.4µin (1.00µm) gold plating, which is double thickness. Thicker plating extends mating cycle life and improves performance in high-cycle applications and corrosive environments.

Q: Are inventory levels adequate for both original and substitute parts?

A: Yes. The original JBXFD2G05MSSDSMR has 933 units in stock. LEMO substitutes have 1001-1022 units in stock across the three variants, providing reliable availability for immediate procurement.
