Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1G04MCSDSR is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 4
• Termination Method: Crimp
• Fastening Type: Push-Pull
• Shielding: Shielded
• Contact Finish: Gold
• Insert Material: Polyetheretherketone (PEEK)
• Mounting Type: Free Hanging (In-Line)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current Rating: 10A (equal or higher acceptable)
• Voltage Rating: 900V (equal or higher acceptable)
• Operating Temperature Range: -40°C to 125°C (equal or wider range acceptable)
• Shell Finish: Chrome over Nickel or Chrome (equivalent corrosion protection)
• Contact Finish Thickness: 19.7µin or higher (equal or greater acceptable)
• Ingress Protection: IP40 or higher (equal or better acceptable)

The substitute part FGG.1B.304.CYCD52 from LEMO meets all mandatory matching parameters and demonstrates allowable variations in operating temperature range (-55°C to 250°C), ingress protection (IP50), and contact finish thickness (39.4µin).

Parameter Comparison

Engineering Selection Recommendations

Primary Part: JBXFD1G04MCSDSR

Use the primary part when:

• Souriau-Sunbank by Eaton supply chain is established and preferred
• Voltage rating specification of 900V is explicitly required in system design
• Operating temperature range of -40°C to 125°C meets application requirements
• Inventory availability of 685 units supports project timeline

Substitute Part: FGG.1B.304.CYCD52

Use the substitute part when:

• LEMO supply chain provides cost or lead-time advantage
• Extended operating temperature range (-55°C to 250°C) is beneficial for application
• Enhanced ingress protection (IP50) is required over base specification (IP40)
• Increased contact finish thickness (39.4µin) provides additional durability margin
• Inventory availability of 677 units supports project timeline

Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Both parts carry UL94 V-0 flammability rating. Selection between primary and substitute parts is based on supply chain preference, application environmental requirements, and project scheduling constraints.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.304.CYCD52 be used as a direct replacement for JBXFD1G04MCSDSR?

A: Yes, within the specified application parameters. Both connectors share identical core specifications: 4-position male plug, crimp termination, push-pull fastening, shielded construction, 10A current rating, gold-plated contacts, and PEEK inserts. The substitute part exceeds the primary part in operating temperature range, ingress protection, and contact finish thickness, making it functionally compatible for applications within the primary part's operating envelope.

Q: What is the difference in shell finish between the two parts?

A: The primary part features Chrome over Nickel plating, while the substitute part features Chrome plating. Both finishes provide corrosion protection suitable for industrial, instrumentation, medical, and telecommunications applications. Chrome over Nickel offers additional corrosion resistance in harsh environments, while Chrome plating is standard for general-purpose applications.

Q: Why is the voltage rating not specified for the LEMO substitute part?

A: The LEMO FGG.1B.304.CYCD52 datasheet does not include a voltage rating specification in the provided parameters. The primary part specifies 900V. When voltage rating is a critical design parameter, verification with the LEMO manufacturer is required to confirm suitability for the intended application.

Q: Does the higher contact finish thickness on the substitute part affect compatibility?

A: No. The substitute part's contact finish thickness of 39.4µin (1.00µm) exceeds the primary part's 19.7µin (0.50µm). Increased plating thickness provides enhanced durability and extended contact life, making it compatible with and beneficial for applications requiring the primary part's specifications.

Q: Are there any packaging differences between the two parts?

A: The primary part packaging is listed as unspecified, while the substitute part is packaged in Bulk. Packaging format does not affect electrical or mechanical compatibility. Confirm packaging requirements with procurement based on assembly and inventory management needs.

Q: What applications are these connectors suitable for?

A: The primary part is specified for Industrial, Instrumentation, Medical, and Telecommunications applications. The substitute part does not list specific applications in the provided parameters. Both connectors' specifications support these application categories based on their electrical ratings, temperature range, and compliance certifications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both JBXFD1G04MCSDSR and FGG.1B.304.CYCD52 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for industrial component sourcing.
