JBXFD1G04MCSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD1G04MCSDSMR is a 4-position circular connector plug manufactured by Souriau-Sunbank by Eaton, featuring male pins with crimp termination. This connector is part of the JBX series and is currently in active production status. The connector is designed for free-hanging, in-line applications requiring shielded connections with push-pull fastening. Finding equivalent substitute parts is necessary when the primary part is unavailable, when inventory constraints exist, or when alternative sourcing is required while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JBXFD1G04MCSDSMR is permissible with parts that maintain the following critical parameters:

Mandatory Compatibility Parameters:

• 4-position connector configuration
• Male pin connector type
• Crimp termination method
• Push-pull fastening mechanism
• Shielded design
• 10A current rating capability
• Gold contact finish on mating surfaces
• UL94 V-0 flammability rating
• ROHS3 compliance

Allowable Variations:

• Shell size designation (1 vs. 304)
• Shell finish specification (Chrome over Nickel vs. Chrome)
• Ingress protection rating (IP40 vs. IP50)
• Operating temperature range (provided minimum and maximum are within or exceed original specifications)
• Contact finish thickness (provided minimum gold plating is maintained)
• Voltage rating (provided it meets or exceeds 900V requirement)

The FGG.1B.304.CYCD52 manufactured by LEMO meets these substitution criteria as a functionally equivalent alternative.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: JBXFD1G04MCSDSMR

The JBXFD1G04MCSDSMR maintains active production status with 930 units in current inventory. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial, instrumentation, medical, and telecommunications applications.

Substitute Part: FGG.1B.304.CYCD52

The FGG.1B.304.CYCD52 is an active production substitute manufactured by LEMO with 677 units in inventory. This part satisfies all mandatory compatibility parameters for direct substitution. The substitute provides enhanced environmental protection (IP50 vs. IP40) and extended operating temperature range (-55°C ~ 250°C vs. -40°C ~ 125°C), making it suitable for applications requiring broader environmental tolerance. Both parts maintain identical compliance certifications (ROHS3, REACH unaffected, EAR99 classification).

Selection between these parts should be based on availability, delivery timeline, and application-specific environmental requirements. Both parts are suitable for equivalent electrical and mechanical performance in 4-position, 10A, shielded connector applications.

Frequently Asked Questions (FAQ)

Q: Can the FGG.1B.304.CYCD52 be used as a direct replacement for the JBXFD1G04MCSDSMR?

A: Yes. Both connectors share identical critical specifications: 4-position configuration, male pin type, crimp termination, push-pull fastening, 10A current rating, gold contact finish, and UL94 V-0 flammability rating. The substitute meets or exceeds the original part specifications in ingress protection and operating temperature range.

Q: What are the differences between these two connector models?

A: The primary differences are shell size designation (1 vs. 304), shell finish specification (Chrome over Nickel vs. Chrome), ingress protection rating (IP40 vs. IP50), and operating temperature range (-40°C ~ 125°C vs. -55°C ~ 250°C). The substitute provides enhanced environmental sealing and broader temperature tolerance.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: Both connectors use identical push-pull fastening mechanisms, PEEK insert material, and brass shell construction. Mechanical compatibility is maintained. Physical dimensions may differ due to shell size designation differences; verify mechanical fit in your specific application housing.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the JBXFD1G04MCSDSMR and FGG.1B.304.CYCD52 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the significance of the different contact finish thickness specifications?

A: The JBXFD1G04MCSDSMR specifies 19.7µin (0.50µm) gold plating, while the FGG.1B.304.CYCD52 specifies 39.4µin (1.00µm). The substitute provides double the gold plating thickness, which enhances contact durability and corrosion resistance without affecting electrical performance.

Q: Can these connectors be used interchangeably in medical applications?

A: Both connectors are listed for medical applications and maintain identical UL94 V-0 flammability ratings and compliance certifications. Interchangeability in medical applications depends on specific device requirements and regulatory approvals for your particular medical device.

Q: What is the difference between IP40 and IP50 ingress protection ratings?

A: IP40 provides protection against objects larger than 1mm and splash water. IP50 provides dust protection and water jet protection. The substitute's IP50 rating offers enhanced environmental sealing suitable for more demanding industrial environments.
