JBXFD1A08MCSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD1A08MCSDSR is an 8-position circular connector plug with male pins manufactured by Souriau-Sunbank by Eaton. This connector features crimp termination, push-pull fastening, and gold-plated mating contacts suitable for industrial, instrumentation, medical, and telecommunications applications. The part is currently active in production with 1002 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific cable opening requirements necessitate alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JBXFD1A08MCSDSR is determined by the following critical parameters that must remain constant across all equivalent parts:

Fixed Parameters (Non-Negotiable):

• Connector type: Plug with male pins
• Position count: 8 positions
• Termination: Crimp
• Fastening mechanism: Push-Pull
• Shielding: Shielded configuration
• Current rating: 5A
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass construction
• Insert material: Polyetheretherketone (PEEK)
• Flammability rating: UL94 V-0
• Compliance: ROHS3 Compliant, REACH Unaffected

Variable Parameters (Application-Dependent):

• Cable opening diameter: Varies by substitute part to accommodate different cable gauges
• Operating temperature range: Extended in substitute parts
• Ingress protection rating: IP50 in substitutes versus IP40 in main part
• Shell finish: Chrome in substitutes versus Chrome over Nickel in main part
• Contact finish thickness: 39.4µin (1.00µm) in substitutes versus 19.7µin (0.50µm) in main part

The three LEMO substitute parts (FGG.1B.308.CYCD52, FGG.1B.308.CYCD62, FGG.1B.308.CYCD72) differ only in cable opening specifications, allowing selection based on the specific cable diameter requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

All four connector models maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between the JBXFD1A08MCSDSR and the LEMO FGG.1B.308 series substitutes is determined by cable diameter requirements and environmental operating conditions.

Primary Part Selection (JBXFD1A08MCSDSR): Select when cable opening diameter is not specified or when the application operates within the -40°C to 125°C temperature range with IP40 ingress protection requirements.

Substitute Selection (LEMO FGG.1B.308 Series): The three LEMO substitute parts provide identical electrical and mechanical functionality with extended operating temperature capability (-55°C to 250°C) and enhanced ingress protection (IP50). Selection among the three LEMO variants is based solely on cable opening diameter:

• FGG.1B.308.CYCD52: Cable opening 0.165" ~ 0.205" (4.20mm ~ 5.20mm)
• FGG.1B.308.CYCD62: Cable opening 0.205" ~ 0.244" (5.20mm ~ 6.20mm)
• FGG.1B.308.CYCD72: Cable opening 0.244" ~ 0.283" (6.20mm ~ 7.20mm)

All substitute parts maintain the 5A current rating, gold contact finish, crimp termination, push-pull fastening, and PEEK insert material required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.308.CYCD52, FGG.1B.308.CYCD62, and FGG.1B.308.CYCD72 be used interchangeably?

A: No. These three LEMO parts differ in cable opening diameter specifications. Selection must match the cable gauge of the application. Using an incorrect cable opening size results in improper cable seating and connector reliability issues.

Q: What is the primary difference between the JBXFD1A08MCSDSR and LEMO substitutes?

A: The LEMO substitutes provide extended operating temperature range (-55°C to 250°C versus -40°C to 125°C) and enhanced ingress protection (IP50 versus IP40). Cable opening diameter varies among the three LEMO options. All other electrical and mechanical parameters remain equivalent.

Q: Are the LEMO FGG.1B.308 series parts compatible with the JBXFD1A08MCSDSR in terms of mating?

A: Functional compatibility is determined by matching cable opening diameter to the application requirements. The connectors share identical position count (8), termination method (crimp), fastening type (push-pull), and contact finish (gold), ensuring electrical and mechanical compatibility when cable specifications are met.

Q: What inventory levels are available for each part?

A: JBXFD1A08MCSDSR: 1002 units; FGG.1B.308.CYCD52: 975 units; FGG.1B.308.CYCD62: 991 units; FGG.1B.308.CYCD72: 703 units. All parts are new original stock.

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

A: Yes. All four connector models are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and share the same HTSUS code (8536.69.4020). All maintain UL94 V-0 flammability rating.

Q: How should cable opening diameter be determined for substitute selection?

A: Cable opening diameter is specified by the cable gauge used in the application. Measure the outer diameter of the cable jacket and select the LEMO variant whose cable opening range encompasses this measurement. Consult application documentation or cable specifications for exact diameter requirements.
