JBXFD1A04MCSDSR Circular Connector Plug - Equivalent & Substitute Parts

Part Overview

The JBXFD1A04MCSDSR is a 4-position circular connector plug manufactured by Souriau-Sunbank by Eaton, featuring male pins with crimp termination and push-pull fastening. This connector is classified as Active product status and is designed for industrial, instrumentation, medical, and telecommunications applications. The connector provides shielded construction with gold-plated mating contacts and operates across a temperature range of -40°C to 125°C with a current rating of 10A at 900V.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in applications where the connector serves the same role within system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1A04MCSDSR is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Plug with male pins
• Number of positions: 4
• Termination method: Crimp
• Fastening mechanism: Push-pull
• Insert material: Polyetheretherketone (PEEK)
• Contact finish: Gold plating on mating surfaces
• Shielding configuration: Shielded construction
• Current rating: 10A minimum
• Flammability compliance: UL94 V-0

Allowable Variations:

• Shell size designations (1 vs. 304) reflect different manufacturer sizing conventions
• Orientation codes (A vs. G) indicate manufacturer-specific keying systems
• Operating temperature ranges may extend beyond the main part specification
• Ingress protection ratings may exceed the minimum IP40 requirement
• Contact finish thickness variations are acceptable within industry standards
• Backshell material and plating specifications may differ while maintaining functional equivalence

The substitute part FGG.1B.304.CYCD52 from LEMO satisfies all mandatory matching parameters and is therefore classified as a functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Product Status Alignment: Both the JBXFD1A04MCSDSR and FGG.1B.304.CYCD52 maintain Active product status, ensuring continued manufacturer support and availability.

Compliance Certification: Both parts achieve ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for industrial and medical applications. Both carry UL94 V-0 flammability ratings, satisfying safety standards for controlled environments.

Electrical Performance: The JBXFD1A04MCSDSR specifies 900V rating; the FGG.1B.304.CYCD52 does not specify voltage rating in provided data. Both support 10A current capacity. Selection should confirm voltage requirements align with application specifications.

Environmental Operating Range: The FGG.1B.304.CYCD52 extends operating temperature to -55°C to 250°C, exceeding the JBXFD1A04MCSDSR range of -40°C to 125°C. This provides broader thermal compatibility for applications requiring extended temperature operation.

Ingress Protection: The FGG.1B.304.CYCD52 provides IP50 dust protection versus IP40 on the main part, offering enhanced environmental sealing for applications in contaminated environments.

Mechanical Compatibility: Shell size designations differ (1 vs. 304) reflecting manufacturer conventions. Orientation codes (A vs. G) indicate different keying systems. Physical mating compatibility must be verified against mating receptacle specifications before deployment.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.304.CYCD52 directly replace JBXFD1A04MCSDSR in existing assemblies?

A: Direct physical replacement depends on mating receptacle compatibility. The shell size designations (1 vs. 304) and orientation codes (A vs. G) reflect different manufacturer standards. Verify that the mating receptacle accepts the LEMO connector geometry and keying before substitution.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution requires matching: 4-position configuration, male pin connector type, crimp termination, push-pull fastening, PEEK insert material, gold contact finish, shielded construction, 10A current capacity, and UL94 V-0 flammability rating. Variations in shell size designation, orientation code, operating temperature range, and ingress protection level are allowable.

Q: Does the FGG.1B.304.CYCD52 meet the 900V voltage requirement?

A: The FGG.1B.304.CYCD52 voltage rating is not specified in available data. Applications requiring 900V operation must obtain voltage specification confirmation from LEMO before substitution.

Q: What is the difference in operating temperature ranges?

A: The JBXFD1A04MCSDSR operates -40°C to 125°C. The FGG.1B.304.CYCD52 operates -55°C to 250°C. The LEMO part provides extended low-temperature and high-temperature capability, suitable for broader environmental applications.

Q: How do shell size and orientation differences affect compatibility?

A: Shell size (1 vs. 304) and orientation (A vs. G) are manufacturer-specific designations. These differences affect physical mating geometry and keying. Compatibility requires verification that the mating receptacle accepts the substitute connector's physical form factor and keying system.

Q: Are both parts compliant with current regulatory standards?

A: Both parts are ROHS3 compliant and REACH Unaffected. Both carry UL94 V-0 flammability certification. Both are classified under ECCN EAR99 and HTSUS 8536.69.4020. Regulatory compliance is equivalent.

Q: What is the difference in ingress protection ratings?

A: The JBXFD1A04MCSDSR provides IP40 protection (splash resistant). The FGG.1B.304.CYCD52 provides IP50 protection (dust protected). The LEMO part offers enhanced environmental sealing for applications in dusty or contaminated environments.

Q: Are crimp termination specifications identical?

A: Both parts use crimp termination. Contact finish thickness differs: JBXFD1A04MCSDSR specifies 19.7µin (0.50µm); FGG.1B.304.CYCD52 specifies 39.4µin (1.00µm). The LEMO part provides thicker gold plating, potentially extending contact life in high-cycle applications.
