JBXFD1A07MSSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD1A07MSSDSR is a 7-position circular connector plug with male pins manufactured by Souriau-Sunbank by Eaton. This shielded connector features solder cup termination, gold-plated mating contacts, and is rated for 7A at 660V across an operating temperature range of -40°C to 125°C. The connector is designed for industrial, instrumentation, medical, and telecommunications applications.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 7-position configuration, male pin connector type, solder cup termination, push-pull fastening, shielded design, and gold contact finish. Substitutes must maintain compatibility with these fundamental specifications while accommodating variations in cable opening dimensions and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD1A07MSSDSR are qualified based on the following core parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Connector type: Plug with male pins
• Number of positions: 7
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding: Shielded design
• Contact finish: Gold plating on mating surfaces
• Current rating: 7A minimum
• Insert material: Polyetheretherketone (PEEK)
• Material flammability: UL94 V-0
• Regulatory compliance: ROHS3 compliant, REACH unaffected

Variable Parameters Allowing Substitution:

• Cable opening dimensions (accommodates different cable gauges)
• Operating temperature range (substitutes may extend beyond -40°C to 125°C)
• Shell finish (chrome acceptable as alternative to chrome over nickel)
• Voltage rating (substitutes without specified voltage rating do not restrict application)
• Ingress protection rating (IP50 exceeds IP40 requirement)
• Contact finish thickness (variations in gold plating thickness)

The four identified substitute parts—FGG.1B.307.CLAD42, FGG.1B.307.CLAD52Z, FGG.1B.307.CLAD62, and FGG.1B.307.CLAD72—all satisfy the mandatory matching parameters and differ only in cable opening specifications, which determine suitability for specific cable diameters.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and full compliance with ROHS3 and REACH regulations, matching the regulatory standing of the JBXFD1A07MSSDSR.

FGG.1B.307.CLAD42 (LEMO): Suitable for applications requiring cable diameters between 3.10mm and 4.20mm. Extends operating temperature range to -55°C to 250°C and provides enhanced ingress protection at IP50. Contact finish thickness of 39.4µin (1.00µm) exceeds the main part specification of 19.7µin (0.50µm).

FGG.1B.307.CLAD52Z (PEI-Genesis): Accommodates cable diameters between 5.20mm and 6.20mm. Limited technical data provided; current rating and operating temperature range not specified in available documentation.

FGG.1B.307.CLAD62 (LEMO): Designed for cable diameters between 5.20mm and 6.20mm. Extends operating temperature range to -55°C to 250°C and provides IP50 ingress protection. Contact finish thickness of 39.4µin (1.00µm) exceeds main part specification.

FGG.1B.307.CLAD72 (LEMO): Accommodates larger cable diameters between 6.20mm and 7.20mm. Extends operating temperature range to -55°C to 250°C and provides IP50 ingress protection. Contact finish thickness of 39.4µin (1.00µm) exceeds main part specification. Moisture sensitivity level specified as 1 (Unlimited), matching the main part.

Selection among substitutes is determined by cable diameter requirements. All LEMO variants (CLAD42, CLAD62, CLAD72) provide superior environmental protection and extended temperature performance compared to the original part.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the JBXFD1A07MSSDSR?

A: Substitutes must maintain identical specifications for connector type (plug with male pins), number of positions (7), termination method (solder cup), fastening mechanism (push-pull), shielding (shielded), contact finish (gold), current rating (7A), insert material (PEEK), and flammability rating (UL94 V-0). Cable opening dimensions vary among substitutes to accommodate different cable gauges.

Q: How do cable opening dimensions affect part selection?

A: Cable opening dimensions determine the range of cable diameters that can be properly terminated in the solder cup. FGG.1B.307.CLAD42 accepts cables 3.10mm to 4.20mm in diameter, FGG.1B.307.CLAD62 accepts 5.20mm to 6.20mm, and FGG.1B.307.CLAD72 accepts 6.20mm to 7.20mm. Select the substitute variant matching your cable diameter specification.

Q: Are the LEMO substitutes compatible with the original Souriau-Sunbank connector?

A: All substitute parts share identical connector type, pin configuration, termination method, and fastening mechanism. Mechanical and electrical compatibility is maintained across all variants. Differences in shell finish (chrome versus chrome over nickel) and contact finish thickness do not affect functional compatibility.

Q: What is the advantage of the extended operating temperature range in substitute parts?

A: LEMO variants (CLAD42, CLAD62, CLAD72) operate from -55°C to 250°C compared to the original part's -40°C to 125°C range. This extended range accommodates applications requiring operation in more extreme thermal environments without requiring alternative connector selection.

Q: Does the IP50 ingress protection rating of substitutes provide additional benefit?

A: IP50 (dust protected) provides enhanced environmental protection compared to the original part's IP40 rating. IP50 prevents dust ingress while maintaining the same liquid splash resistance as IP40. This upgrade is beneficial in industrial and instrumentation environments with higher contamination risk.

Q: What is the significance of contact finish thickness differences?

A: The original part specifies 19.7µin (0.50µm) gold plating thickness on mating contacts. LEMO substitutes provide 39.4µin (1.00µm) thickness, which is double the specification. Thicker gold plating extends contact life and improves corrosion resistance in demanding applications.

Q: Is FGG.1B.307.CLAD52Z (PEI-Genesis) suitable for all applications?

A: FGG.1B.307.CLAD52Z maintains core electrical and mechanical compatibility but lacks complete technical documentation for current rating and operating temperature range. This part is suitable for applications where cable diameter requirements fall within the 5.20mm to 6.20mm range and where extended temperature or current specifications are not critical.

Q: Can substitutes be used interchangeably in existing designs?

A: Substitutes are mechanically and electrically interchangeable provided cable diameter matches the selected variant's cable opening specification. No design modifications are required. Verify cable diameter compatibility before implementation.
