JBXFD2G08MSSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD2G08MSSDSR is an 8-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 940 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 JBXFD2G08MSSDSR are identified from the LEMO 2B series based on the following substitution criteria:

Core Compatibility Parameters:

• Number of Positions: 8
• Connector Type: Plug, Male Pins
• Termination: Solder Cup
• Fastening Type: Push-Pull
• Shielding: Shielded
• Current Rating: 10A
• Contact Finish - Mating: Gold
• Shell Material: Brass
• Insert Material: Polyetheretherketone (PEEK)
• Material Flammability Rating: UL94 V-0
• Orientation: G

Differentiation Parameter: The LEMO substitute parts are differentiated by cable opening specifications, which determine compatibility with specific cable gauges. Four variants are available: FGG.2B.308.CLAZ (unspecified cable opening), FGG.2B.308.CLAD52 (0.165" ~ 0.205"), FGG.2B.308.CLAD62 (0.205" ~ 0.244"), and FGG.2B.308.CLAD72 (0.244" ~ 0.283"). Selection among these variants depends on the cable diameter requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the primary part. The LEMO 2B series substitutes provide enhanced operating temperature range (-55°C ~ 250°C versus -40°C ~ 125°C) and improved ingress protection (IP50 versus IP40), with thicker gold plating on contacts (39.4µin versus 19.7µin).

Selection among LEMO variants should be based on cable opening requirements:

• FGG.2B.308.CLAD52: Cable opening 0.165" ~ 0.205" (4.20mm ~ 5.20mm)
• FGG.2B.308.CLAD62: Cable opening 0.205" ~ 0.244" (5.20mm ~ 6.20mm)
• FGG.2B.308.CLAD72: Cable opening 0.244" ~ 0.283" (6.20mm ~ 7.20mm)
• FGG.2B.308.CLAZ: Cable opening unspecified

All substitute parts maintain the same electrical performance (10A current rating), mechanical interface (8-position, push-pull fastening), and material composition (PEEK insert, brass shell, gold-plated contacts) as the primary part.

Frequently Asked Questions (FAQ)

Q: Can LEMO FGG.2B.308 series connectors directly replace the JBXFD2G08MSSDSR?

A: Yes, the LEMO FGG.2B.308 series connectors are functionally equivalent substitutes. All variants share identical electrical ratings (10A), connector configuration (8-position plug with male pins), termination method (solder cup), and fastening mechanism (push-pull). The primary selection criterion is cable opening compatibility.

Q: What is the difference between the four LEMO substitute variants?

A: The four variants differ only in cable opening specifications, which accommodate different cable diameters. FGG.2B.308.CLAD52, CLAD62, and CLAD72 are designated for specific cable gauge ranges. FGG.2B.308.CLAZ has unspecified cable opening. Selection depends on the cable diameter used in the application.

Q: Are there differences in operating temperature between the primary part and substitutes?

A: Yes. The JBXFD2G08MSSDSR operates from -40°C to 125°C, while all LEMO substitutes operate from -55°C to 250°C. The LEMO variants provide extended temperature capability, suitable for applications requiring broader thermal performance.

Q: How do the ingress protection ratings compare?

A: The JBXFD2G08MSSDSR has IP40 rating, while all LEMO substitutes have IP50 rating (dust protected). The IP50 rating provides enhanced environmental protection.

Q: Is the gold plating thickness the same on all parts?

A: No. The JBXFD2G08MSSDSR has 19.7µin (0.50µm) gold plating, while all LEMO substitutes have 39.4µin (1.00µm) gold plating. The thicker plating on LEMO parts provides enhanced durability and contact reliability.

Q: Are all parts RoHS compliant?

A: Yes. The primary part and all four substitute variants are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the inventory status for these parts?

A: The JBXFD2G08MSSDSR has 940 units in stock. LEMO substitutes have varying inventory: FGG.2B.308.CLAZ (993 units), FGG.2B.308.CLAD52 (1121 units), FGG.2B.308.CLAD62 (790 units), and FGG.2B.308.CLAD72 (762 units).

Q: Can I use any LEMO variant interchangeably?

A: No. Cable opening compatibility must be matched to the specific cable diameter in your application. Using an incorrect cable opening variant may result in improper cable seating or mechanical failure. Verify cable diameter specifications before selecting a variant.
