Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1A03MSSDSR is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Connector type: Plug with male pins
• Position count: 3 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull coupling
• Shielding configuration: Shielded design
• Contact finish: Gold plating on mating surfaces
• Insert material: PEEK
• Current capacity: 12A minimum
• Regulatory compliance: ROHS3 and REACH compliance

The substitute part FGG.1B.303.CLAD62 manufactured by LEMO satisfies all critical matching parameters. Both connectors employ identical termination technology, pin configuration, and environmental sealing principles, enabling functional equivalence in applications requiring 3-position circular connector plugs with solder cup termination.

Parameter Comparison

Engineering Selection Recommendations

Both the JBXFD1A03MSSDSR and FGG.1B.303.CLAD62 maintain active product status and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts is based on application-specific environmental and operational requirements:

JBXFD1A03MSSDSR Selection Criteria:

• Applications operating within -40°C to 125°C temperature envelope
• Environments requiring IP40 ingress protection classification
• Voltage requirements up to 600V
• Current demands at 12A capacity

FGG.1B.303.CLAD62 Selection Criteria:

• Applications requiring extended temperature operation from -55°C to 250°C
• Environments demanding IP50 dust protection rating
• Enhanced contact finish thickness (39.4µin vs. 19.7µin) for extended mating cycle durability
• Cable opening specifications of 0.205" to 0.244" (5.20mm to 6.20mm)

Both connectors deliver equivalent electrical performance at 12A current rating with gold-plated contacts and PEEK inserts. The LEMO substitute provides superior environmental sealing and thermal capability, while the Souriau-Sunbank main part offers established supply availability with 869 units in inventory.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.303.CLAD62 directly replace JBXFD1A03MSSDSR in existing applications?

A: Direct replacement is supported when the application environment operates within the overlapping parameter ranges. Both connectors share identical 3-position configuration, solder cup termination, 12A current rating, push-pull fastening, and PEEK insert material. Verify that the application's operating temperature range (-40°C to 125°C for the main part) and ingress protection requirements (IP40 minimum) are satisfied.

Q: What are the differences in contact finish specifications?

A: The JBXFD1A03MSSDSR provides 19.7µin (0.50µm) gold plating thickness on mating contacts. The FGG.1B.303.CLAD62 provides 39.4µin (1.00µm) gold plating thickness. The thicker plating on the LEMO substitute extends contact durability under repeated mating cycles and provides enhanced corrosion resistance in demanding environments.

Q: Are there voltage rating differences between these connectors?

A: The JBXFD1A03MSSDSR specifies 600V voltage rating. The FGG.1B.303.CLAD62 does not provide a voltage specification in the available parameters. Confirm voltage compatibility with the LEMO connector documentation before substitution in high-voltage applications.

Q: What is the significance of the IP50 rating on the LEMO connector?

A: The FGG.1B.303.CLAD62 provides IP50 dust protection classification, compared to IP40 on the Souriau-Sunbank part. IP50 rating indicates complete protection against dust ingress, suitable for environments with higher particulate contamination. The main part's IP40 rating provides protection against splashing water and larger particles.

Q: How do the operating temperature ranges affect substitution decisions?

A: The JBXFD1A03MSSDSR operates from -40°C to 125°C. The FGG.1B.303.CLAD62 operates from -55°C to 250°C. The LEMO substitute accommodates wider temperature extremes, enabling use in cryogenic and high-temperature industrial applications beyond the main part's capability. For applications within -40°C to 125°C, both connectors perform equivalently.

Q: Are both connectors RoHS and REACH compliant?

A: Both the JBXFD1A03MSSDSR and FGG.1B.303.CLAD62 maintain ROHS3 compliance and REACH unaffected status, confirming suitability for regulated markets and applications requiring environmental compliance documentation.

Q: What packaging considerations apply to these connectors?

A: The JBXFD1A03MSSDSR is supplied in standard packaging with 869 units currently in inventory. The FGG.1B.303.CLAD62 is supplied in bulk packaging with 907 units in inventory. Confirm packaging requirements and lead time availability with your procurement process before finalizing substitution decisions.
