JBXFD2G12MWSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD2G12MWSDSMR is a 12-position circular connector plug with male pins manufactured by Souriau-Sunbank by Eaton. This connector is classified as an active product with 1033 units in stock. The connector features gold-plated mating contacts, chrome over nickel shell finish, and is rated for 7A at 830V with an operating temperature range of -40°C to 125°C. This connector is designed for industrial, instrumentation, medical, and telecommunications applications requiring shielded, push-pull fastening circular connectors. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative termination methods or operational specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G12MWSDSMR are identified based on strict equivalence of core electrical and mechanical parameters. The substitution logic is based on the following criteria:

Primary Equivalence Parameters:

• Connector type: Plug with male pins
• Number of positions: 12
• Fastening mechanism: Push-pull
• Orientation: G
• Shell material: Brass
• Contact finish: Gold
• Shielding: Shielded
• Current rating: 7A
• Insert material: PEEK
• Flammability rating: UL94 V-0

Allowable Variations:

• Termination method (push-pull connector to solder cup termination)
• Shell finish (chrome over nickel to chrome)
• Operating temperature range (extended range acceptable)
• Ingress protection rating (IP40 to IP50)
• Contact finish thickness (19.7µin to 39.4µin)

The substitute parts FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82 manufactured by LEMO maintain electrical compatibility through equivalent current ratings, gold contact finish, and shielded configuration. Both substitutes feature solder cup termination, which represents a different connection method suitable for applications requiring permanent wire attachment rather than push-pull mating.

Parameter Comparison

Engineering Selection Recommendations

Selection between the JBXFD2G12MWSDSMR and its substitute parts is determined by termination method requirements and operational environment specifications.

JBXFD2G12MWSDSMR Selection Criteria:

• Applications requiring push-pull mating connector interface
• Systems designed for repeated connection and disconnection cycles
• Installations where in-line free-hanging connector configuration is specified
• Operating environments within -40°C to 125°C range

FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82 Selection Criteria:

• Applications requiring solder cup wire termination for permanent connections
• Systems operating in extended temperature ranges up to 250°C
• Installations requiring enhanced ingress protection (IP50 dust protection)
• Cable assemblies with specific cable opening requirements (CLAD52: 4.20mm-5.20mm; CLAD82: 7.20mm-8.20mm)

All three parts maintain ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability rating. Current rating equivalence (7A) ensures electrical compatibility for applications within specified amperage limits. The 12-position configuration, gold contact finish, shielded design, and PEEK insert material are consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.312.CLAD52 or FGG.2B.312.CLAD82 directly replace JBXFD2G12MWSDSMR in existing assemblies?

A: Direct mechanical replacement is not possible. The JBXFD2G12MWSDSMR features push-pull mating connector termination, while FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82 feature solder cup termination. Substitution requires redesign of the mating interface and wire attachment methodology.

Q: What is the difference between FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82?

A: Both parts are identical except for cable opening specifications. FGG.2B.312.CLAD52 accommodates cable diameters of 4.20mm to 5.20mm. FGG.2B.312.CLAD82 accommodates cable diameters of 7.20mm to 8.20mm. Selection depends on the cable gauge used in the application.

Q: Are the substitute parts rated for the same voltage as JBXFD2G12MWSDSMR?

A: The JBXFD2G12MWSDSMR is rated for 830V. Voltage ratings are not specified for FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82. Applications requiring 830V operation must confirm voltage compatibility with LEMO specifications before substitution.

Q: Do all three parts meet the same compliance standards?

A: Yes. JBXFD2G12MWSDSMR, FGG.2B.312.CLAD52, and FGG.2B.312.CLAD82 are all ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for flammability. All three parts have MSL rating of 1 (unlimited moisture sensitivity).

Q: What is the current rating for all substitute options?

A: All three parts are rated for 7A continuous current, ensuring electrical compatibility for applications within this amperage specification.

Q: Can the substitute parts operate at the same temperature range as JBXFD2G12MWSDSMR?

A: The JBXFD2G12MWSDSMR operates from -40°C to 125°C. FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82 operate from -55°C to 250°C, providing extended temperature capability. Applications within the -40°C to 125°C range are compatible with all three parts.

Q: Are the contact finishes equivalent across all three parts?

A: All three parts feature gold-plated mating contacts. Contact finish thickness differs: JBXFD2G12MWSDSMR has 19.7µin (0.50µm) thickness, while FGG.2B.312.CLAD52 and FGG.2B.312.CLAD82 have 39.4µin (1.00µm) thickness. Both thicknesses provide gold contact protection for signal integrity and corrosion resistance.
