JBXFD2G03MSSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD2G03MSSDSMR is a 3-position circular connector plug with male pins and solder cup termination, manufactured by Souriau-Sunbank by Eaton. This connector is part of the JBX series and is designed for industrial, instrumentation, medical, and telecommunications applications. The part is currently active in production with 825 pieces in stock.

Substitute parts are identified when equivalent circular connectors share the same functional characteristics: 3-position configuration, male pin orientation, solder cup termination, push-pull fastening, shielded design, and compatible electrical ratings. Alternative models may be required due to inventory availability, lead time considerations, or specific application requirements within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G03MSSDSMR are qualified based on the following critical parameters that must align with the main part specification:

Mandatory Matching Parameters:

• Connector type: Plug with male pins
• Number of positions: 3
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Current rating: 17A minimum
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass construction
• Insert material: PEEK
• Compliance: ROHS3 compliant, RoHS3 compliant status

Allowable Variations:

• Shell finish: Chrome or chrome over nickel
• Ingress protection rating: IP40 or higher (IP50 acceptable)
• Operating temperature range: May extend beyond -40°C ~ 125°C
• Contact finish thickness: Variations within gold plating specifications
• Voltage rating: Specification may not be provided for substitute parts
• Backshell features: May include backshell with or without boot adapter

The substitute parts FGG.2B.303.CLAD62 and FGG.2B.303.CLAD92Z, both manufactured by LEMO, meet these criteria and are classified as equivalent alternatives.

Parameter Comparison

Engineering Selection Recommendations

JBXFD2G03MSSDSMR (Primary Part)

• Active product status with established supply chain
• 825 pieces currently in stock
• Voltage rating specified at 830V
• Operating temperature range: -40°C ~ 125°C
• Contact finish thickness: 19.7µin (0.50µm)
• Suitable for standard industrial and telecommunications applications within specified temperature limits

FGG.2B.303.CLAD62 (Substitute Option 1)

• Active product status with 1079 pieces in stock
• Extended operating temperature range: -55°C ~ 250°C
• Higher ingress protection rating: IP50
• Contact finish thickness: 39.4µin (1.00µm) - thicker gold plating
• Cable opening: 0.205" ~ 0.244" (5.20mm ~ 6.20mm)
• Suitable for applications requiring extended temperature performance and enhanced dust protection

FGG.2B.303.CLAD92Z (Substitute Option 2)

• Active product status with 911 pieces in stock
• Extended operating temperature range: -55°C ~ 250°C
• Higher ingress protection rating: IP50
• Contact finish thickness: 39.4µin (1.00µm) - thicker gold plating
• Cable opening: 0.323" ~ 0.362" (8.20mm ~ 9.20mm)
• Suitable for applications requiring extended temperature performance, enhanced dust protection, and larger cable diameter accommodation

All three parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications. Selection between substitute options depends on cable diameter requirements and operating temperature specifications of the target application.

Frequently Asked Questions (FAQ)

Q: What are the primary substitution criteria for the JBXFD2G03MSSDSMR?

A: The JBXFD2G03MSSDSMR can be substituted with equivalent 3-position circular connector plugs featuring male pins, solder cup termination, push-pull fastening, shielded design, 17A current rating, gold-plated contacts, brass shell with PEEK insert, and ROHS3 compliance. The substitute parts must maintain these core electrical and mechanical characteristics.

Q: How do the LEMO FGG.2B.303 series parts differ from the Souriau-Sunbank JBXFD2G03MSSDSMR?

A: The primary differences are: (1) Extended operating temperature range from -55°C to 250°C versus -40°C to 125°C; (2) Higher ingress protection rating of IP50 versus IP40; (3) Thicker gold contact plating at 39.4µin versus 19.7µin; (4) Voltage rating not specified for LEMO parts; (5) Different cable opening specifications between CLAD62 and CLAD92Z variants.

Q: What is the significance of cable opening specifications for the FGG.2B.303.CLAD62 and FGG.2B.303.CLAD92Z?

A: Cable opening specifications define the acceptable cable diameter range for proper connector assembly. CLAD62 accommodates 5.20mm to 6.20mm cable diameters, while CLAD92Z accommodates 8.20mm to 9.20mm cable diameters. Selection depends on the actual cable diameter used in the application.

Q: Are all three parts suitable for medical applications?

A: The JBXFD2G03MSSDSMR is explicitly listed for medical applications. The LEMO FGG.2B.303 series parts do not specify medical applications in the provided data. Application suitability must be confirmed through complete product documentation and regulatory requirements for the specific medical device classification.

Q: What is the difference in contact finish thickness between the main part and substitute parts?

A: The JBXFD2G03MSSDSMR has gold contact finish thickness of 19.7µin (0.50µm), while both LEMO substitute parts have 39.4µin (1.00µm) thickness. The thicker plating on substitute parts provides enhanced durability and corrosion resistance for extended service life.

Q: Can the FGG.2B.303 series parts be used in applications requiring 830V operation?

A: The voltage rating is not specified for the LEMO FGG.2B.303 series parts in the provided data. Voltage compatibility must be confirmed through LEMO technical documentation before substitution in high-voltage applications.

Q: What inventory considerations should guide part selection?

A: Current stock levels are: JBXFD2G03MSSDSMR (825 pieces), FGG.2B.303.CLAD62 (1079 pieces), and FGG.2B.303.CLAD92Z (911 pieces). Substitute selection may be influenced by inventory availability and lead time requirements for production schedules.
