JBXFD1A04MCSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD1A04MCSDSMR 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 part of the JBX series and is classified as Active product status with 683 units in current inventory. The connector is designed for applications requiring shielded, free-hanging inline connections in industrial, instrumentation, medical, and telecommunications environments. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate multiple qualified suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1A04MCSDSMR 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
• Shielding configuration: Shielded
• Current rating: 10A minimum
• Contact finish: Gold plating on mating surfaces
• Insert material: Polyetheretherketone (PEEK)
• Compliance: ROHS3 Compliant, REACH Unaffected

Allowable Variation Parameters:

• Shell size designation (different manufacturer nomenclature permitted)
• Operating temperature range (substitute may exceed specified range)
• Ingress protection rating (substitute may exceed IP40)
• Voltage rating (substitute may exceed 900V)
• Contact finish thickness (substitute may exceed 19.7µin specification)
• Shell finish composition (chrome or chrome over nickel acceptable)

The substitute part FGG.1B.304.CYCD52 from LEMO meets all mandatory matching criteria and qualifies as an equivalent substitute.

Engineering Selection Recommendations

Primary Part Selection: JBXFD1A04MCSDSMR

The JBXFD1A04MCSDSMR remains the preferred selection when available. This part carries Active product status with confirmed inventory of 683 units. Full electrical and environmental specifications are documented, including voltage rating of 900V and operating temperature range of -40°C to 125°C. The part is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Substitute Part Selection: FGG.1B.304.CYCD52

The FGG.1B.304.CYCD52 from LEMO qualifies as an equivalent substitute when the primary part is unavailable. This substitute maintains all critical functional parameters: 4-position male pin plug configuration, crimp termination, push-pull fastening, shielded design, 10A current rating, gold contact finish, brass shell with PEEK insert, and ROHS3 compliance. The substitute demonstrates enhanced performance characteristics in three areas: ingress protection rating of IP50 exceeds the IP40 specification, operating temperature range of -55°C to 250°C exceeds the -40°C to 125°C specification, and contact finish thickness of 39.4µin exceeds the 19.7µin specification. These enhancements do not create incompatibility and represent acceptable performance margins for industrial, instrumentation, medical, and telecommunications applications. Current inventory for the substitute is 677 units.

Selection Criteria:

• Use JBXFD1A04MCSDSMR as primary choice when available
• Use FGG.1B.304.CYCD52 as qualified substitute when primary part is unavailable
• Both parts are Active status with adequate inventory
• Both parts meet all regulatory compliance requirements
• Mechanical and electrical compatibility is confirmed

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.304.CYCD52 be used as a direct replacement for JBXFD1A04MCSDSMR?

A: Yes. The FGG.1B.304.CYCD52 meets all mandatory compatibility criteria: identical 4-position male pin plug configuration, crimp termination, push-pull fastening, shielded design, 10A current rating, gold contact finish, brass shell, and PEEK insert material. Both parts are ROHS3 Compliant and REACH Unaffected.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer designation and enhanced performance specifications in the LEMO substitute. The LEMO part provides IP50 ingress protection versus IP40, extended operating temperature range of -55°C to 250°C versus -40°C to 125°C, and thicker gold plating at 39.4µin versus 19.7µin. The LEMO part does not specify voltage rating, while the Souriau-Sunbank part specifies 900V.

Q: Are there any compatibility concerns with mechanical fit?

A: No mechanical compatibility concerns exist. Both connectors use identical push-pull fastening mechanisms, crimp termination, and PEEK insert material. Shell size designations differ due to manufacturer nomenclature (Shell Size 1 versus 304), but this reflects different classification systems and does not affect physical compatibility.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. The selection should be based on availability, cost, and specific application requirements. If operating temperature range or ingress protection requirements exceed the primary specification, the LEMO substitute offers enhanced performance margins.

Q: Are both parts suitable for industrial, instrumentation, medical, and telecommunications applications?

A: The JBXFD1A04MCSDSMR is explicitly rated for these applications. The FGG.1B.304.CYCD52 does not specify applications in the provided data, but meets all electrical and environmental parameters required for these application categories.

Q: What is the inventory status for each part?

A: JBXFD1A04MCSDSMR has 683 units in stock. FGG.1B.304.CYCD52 has 677 units in stock. Both parts are classified as New Original and carry Active product status.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and 8536.69.4020 HTSUS code.
