Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G18MSSDSR is determined by the following critical parameters:

Primary Matching Criteria:

• 18-position connector configuration
• Male pin plug connector type
• Solder cup termination method
• Push-pull fastening mechanism
• Shielded construction
• Gold contact finish
• 5.5A current rating capability
• PEEK insert material
• Brass shell with chrome plating

Compliance Requirements:

• ROHS3 compliance
• UL94 V-0 flammability rating
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

The FGG.2B.318.CLAD72Z manufactured by LEMO meets all primary matching criteria and compliance requirements, establishing it as a valid substitute part for the JBXFD2G18MSSDSR.

Parameter Comparison

Engineering Selection Recommendations

Both the JBXFD2G18MSSDSR and FGG.2B.318.CLAD72Z are active product status connectors with full ROHS3 compliance and unlimited moisture sensitivity ratings. The FGG.2B.318.CLAD72Z provides enhanced ingress protection (IP50 versus IP40) and an extended operating temperature range (-55°C to 250°C versus -40°C to 125°C). The JBXFD2G18MSSDSR specifies a 660V voltage rating, while the FGG.2B.318.CLAD72Z does not provide a voltage specification in the available data. Both connectors maintain identical current ratings (5.5A), contact finish (gold), and termination method (solder cup). Selection between these parts should be based on specific application requirements regarding temperature range, ingress protection level, and voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the FGG.2B.318.CLAD72Z directly replace the JBXFD2G18MSSDSR in existing designs?

A: The FGG.2B.318.CLAD72Z is mechanically and electrically compatible as a substitute. Both connectors feature identical 18-position configurations, push-pull fastening, solder cup termination, and 5.5A current ratings. Physical dimensions and mating interfaces are equivalent. Verification of application-specific requirements regarding operating temperature range and ingress protection level is necessary before implementation.

Q: What are the key differences between these two connector models?

A: The primary differences are: (1) Ingress Protection rating—FGG.2B.318.CLAD72Z provides IP50 dust protection versus IP40 for JBXFD2G18MSSDSR; (2) Operating temperature range—FGG.2B.318.CLAD72Z operates from -55°C to 250°C versus -40°C to 125°C for JBXFD2G18MSSDSR; (3) Shell finish—JBXFD2G18MSSDSR uses chrome over nickel while FGG.2B.318.CLAD72Z uses chrome only; (4) Contact finish thickness—FGG.2B.318.CLAD72Z specifies 39.4µin (1.00µm) versus 19.7µin (0.50µm) for JBXFD2G18MSSDSR.

Q: Are both connectors RoHS compliant?

A: Yes, both the JBXFD2G18MSSDSR and FGG.2B.318.CLAD72Z are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have a Moisture Sensitivity Level (MSL) rating of 1, which indicates unlimited shelf life without special moisture control requirements.

Q: Which connector should be selected for high-temperature applications?

A: The FGG.2B.318.CLAD72Z supports operating temperatures up to 250°C, making it suitable for high-temperature applications. The JBXFD2G18MSSDSR is rated to 125°C maximum.

Q: Is the voltage rating difference significant for substitution?

A: The JBXFD2G18MSSDSR specifies 660V rating. The FGG.2B.318.CLAD72Z does not provide a voltage specification in available documentation. Applications requiring voltage ratings above the FGG.2B.318.CLAD72Z capability should retain the JBXFD2G18MSSDSR.
