Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD1G03MSSDSR are identified based on strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Connector type: Plug with male pins
• Number of positions: 3
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Current rating: 12A minimum
• Contact finish: Gold plating

Mechanical Compatibility Parameters:

• Mounting type: Free hanging (in-line)
• Orientation: G
• Primary material: Metal construction
• Insert material: Polyetheretherketone (PEEK)
• Backshell inclusion: Present

Regulatory & Environmental Parameters:

• RoHS3 compliance
• UL94 V-0 flammability rating
• REACH unaffected status
• EAR99 export classification

The LEMO FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z meet all critical substitution criteria. Both parts maintain identical connector type, position count, termination, fastening, shielding, current rating, and contact finish specifications. Both are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected.

Parameter Comparison

Engineering Selection Recommendations

Substitution Validity: Both FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z are valid substitutes for JBXFD1G03MSSDSR based on matching electrical and mechanical specifications. All three parts are active products with current manufacturing status and full regulatory compliance.

Compliance Alignment: All three connectors maintain ROHS3 compliance, UL94 V-0 flammability certification, REACH unaffected status, and identical export classification (EAR99). Tariff classification (HTSUS 8536.69.4020) is consistent across all variants.

Performance Considerations: The LEMO substitutes provide enhanced operating temperature range (-55°C ~ 250°C versus -40°C ~ 125°C) and superior ingress protection (IP50 versus IP40). Contact finish thickness on LEMO parts is doubled (39.4µin versus 19.7µin), providing increased durability in mating cycles. These enhancements represent functional improvements without compromising original specification requirements.

Inventory Availability: JBXFD1G03MSSDSR: 1084 units in stock FGG.1B.303.CLAD62: 907 units in stock FGG.1B.303.CLAD62Z: 946 units in stock

Frequently Asked Questions (FAQ)

Q: What makes FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z acceptable substitutes for JBXFD1G03MSSDSR?

A: Both LEMO parts match the critical electrical and mechanical parameters: 3-position plug configuration, male pins, solder cup termination, push-pull fastening, shielded design, 12A current rating, gold contact finish, PEEK insert material, and identical mounting type. All three parts are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected.

Q: Are there differences between FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z?

A: Both LEMO variants are electrically and mechanically identical. The primary difference is moisture sensitivity level designation: FGG.1B.303.CLAD62 lists MSL as not applicable, while FGG.1B.303.CLAD62Z specifies MSL 1 (unlimited). Both parts function identically in circuit applications.

Q: What are the key differences between the Souriau-Sunbank and LEMO connectors?

A: The LEMO substitutes provide extended operating temperature range (-55°C to 250°C versus -40°C to 125°C), higher ingress protection rating (IP50 versus IP40), and thicker gold plating (39.4µin versus 19.7µin). The Souriau-Sunbank part specifies 600V voltage rating, which is not specified for LEMO variants. Shell finish differs: Souriau-Sunbank uses chrome over nickel, while LEMO uses chrome plating.

Q: Can LEMO FGG.1B.303.CLAD62Z be used in place of JBXFD1G03MSSDSR in existing designs?

A: Yes. The FGG.1B.303.CLAD62Z maintains all critical connector specifications including 3-position configuration, solder cup termination, push-pull fastening, shielding, and 12A current capacity. The enhanced operating temperature range and ingress protection provide additional design margin without requiring circuit modification.

Q: What is the significance of the different shell finishes?

A: JBXFD1G03MSSDSR uses chrome over nickel plating, while LEMO substitutes use chrome plating. Both finishes provide corrosion resistance and electrical conductivity suitable for the specified applications. The chrome over nickel specification on the Souriau-Sunbank part provides additional corrosion protection in harsh environments.

Q: Are all three connectors suitable for medical applications?

A: JBXFD1G03MSSDSR explicitly lists medical applications in its specification. LEMO FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z do not specify applications in the provided data. Both LEMO parts maintain UL94 V-0 flammability rating and ROHS3 compliance, which are standard medical device requirements. Application suitability should be confirmed against specific medical device standards and regulatory requirements.

Q: What is the cable opening specification for the substitute parts?

A: LEMO substitutes specify cable opening as 0.205" ~ 0.244" (5.20mm ~ 6.20mm). The original JBXFD1G03MSSDSR does not specify cable opening in the provided data. Cable compatibility should be verified during component selection.
