Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G18MWSDSR is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Plug with male pins
• Position count: 18 positions
• Shell size compatibility: Insert size 2 or equivalent (318)
• Fastening mechanism: Push-pull
• Orientation: G
• Shielding requirement: Shielded configuration
• Contact finish: Gold-plated mating surfaces
• Insert material: PEEK
• Current capacity: 5.5A minimum
• Regulatory compliance: ROHS3 and REACH requirements

Allowable Variations:

• Termination method (free hanging vs. solder cup)
• Shell finish (chrome over nickel vs. chrome)
• Contact finish thickness (19.7µin vs. 39.4µin)
• Operating temperature range (extended range acceptable)
• Ingress protection rating (IP40 vs. IP50)
• Voltage rating (660V vs. unspecified, provided current rating is met)

The substitute part FGG.2B.318.CLAD72Z meets all primary matching criteria while offering solder cup termination as an alternative to free-hanging configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (JBXFD2G18MWSDSR): Select the JBXFD2G18MWSDSR when free-hanging in-line termination is required and operating temperatures remain within -40°C to 125°C. This part maintains active product status with established inventory availability. ROHS3 compliance and REACH unaffected status confirm regulatory alignment for industrial, instrumentation, medical, and telecommunications applications.

Substitute Part Selection (FGG.2B.318.CLAD72Z): Select FGG.2B.318.CLAD72Z when solder cup termination is specified for direct cable integration or when extended operating temperature range (-55°C to 250°C) is required. This LEMO connector maintains equivalent electrical performance at 5.5A and 18 positions with enhanced dust protection (IP50). Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence.

Compatibility Constraints: Both parts share identical connector type, position count, fastening mechanism, orientation, shielding configuration, and current rating. Substitution is valid only when termination method compatibility is confirmed in the system design. Shell size designation differs (2 vs. 318) but represents equivalent mechanical interfaces within their respective manufacturer specifications.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.318.CLAD72Z directly replace JBXFD2G18MWSDSR in existing assemblies?

A: Direct mechanical replacement is possible only if the system design accommodates solder cup termination instead of free-hanging configuration. Both connectors share identical 18-position, push-pull, shielded architecture with equivalent electrical ratings (5.5A, gold-plated contacts). Verify termination method compatibility before substitution.

Q: What is the difference between shell size 2 and shell size 318?

A: Shell size 2 (JBXFD2G18MWSDSR) and shell size 318 (FGG.2B.318.CLAD72Z) represent manufacturer-specific designations for equivalent mechanical interfaces. Both accommodate 18-position PEEK inserts with identical pin configurations and push-pull fastening. Selection depends on connector series compatibility within the system.

Q: Are both parts suitable for medical applications?

A: JBXFD2G18MWSDSR is explicitly listed for medical applications. FGG.2B.318.CLAD72Z does not specify medical applications in the provided parameters. Verify medical device compliance requirements and certifications independently before selecting FGG.2B.318.CLAD72Z for medical systems.

Q: What is the significance of the different operating temperature ranges?

A: JBXFD2G18MWSDSR operates from -40°C to 125°C, while FGG.2B.318.CLAD72Z operates from -55°C to 250°C. The extended range of the LEMO connector provides flexibility for high-temperature industrial environments. Select based on actual system operating conditions; the narrower range of the Souriau-Sunbank connector is sufficient for standard industrial and telecommunications applications.

Q: Do both connectors meet the same regulatory standards?

A: Both JBXFD2G18MWSDSR and FGG.2B.318.CLAD72Z are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes (8536.69.4020). Regulatory equivalence is confirmed for both parts.

Q: What is the difference in contact finish thickness?

A: JBXFD2G18MWSDSR has 19.7µin (0.50µm) gold plating on mating contacts, while FGG.2B.318.CLAD72Z has 39.4µin (1.00µm). The thicker plating on the LEMO connector provides enhanced durability for high-cycle mating applications. Both thicknesses meet industrial standards for gold-plated circular connectors.

Q: Can these connectors be used interchangeably in telecommunications systems?

A: Both connectors are rated for telecommunications applications with equivalent electrical specifications (5.5A, 660V or unspecified, shielded configuration). Substitution is valid when termination method and operating temperature requirements align with system specifications. Verify connector series compatibility with existing telecommunications infrastructure.
