Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD1G03MSSDSMR are identified based on strict equivalence 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: PEEK
• Flammability rating: UL94 V-0

Regulatory Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99
• HTSUS: 8536.69.4020

The LEMO FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z meet all critical electrical and mechanical parameters required for substitution. Both parts maintain identical connector type, position count, termination method, fastening type, shielding, current rating, and material specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: JBXFD1G03MSSDSMR

The JBXFD1G03MSSDSMR maintains active product status with confirmed inventory of 902 units. This part carries full compliance certifications including ROHS3 and REACH unaffected status. The 600V voltage rating and -40°C to 125°C operating temperature range support standard industrial and telecommunications applications.

Substitute Option 1: FGG.1B.303.CLAD62

The LEMO FGG.1B.303.CLAD62 is functionally equivalent with 907 units in inventory. This part meets all critical electrical and mechanical parameters. The extended operating temperature range of -55°C to 250°C provides broader thermal capability. Ingress protection rating of IP50 exceeds the primary part's IP40 specification. Contact finish thickness of 39.4µin (1.00µm) provides enhanced durability compared to the primary part's 19.7µin (0.50µm). Both parts carry ROHS3 compliance and EAR99 classification.

Substitute Option 2: FGG.1B.303.CLAD62Z

The LEMO FGG.1B.303.CLAD62Z is functionally equivalent with 946 units in inventory. This variant shares identical electrical and mechanical specifications with FGG.1B.303.CLAD62, including the extended -55°C to 250°C operating temperature range and IP50 ingress protection. The MSL rating of 1 (Unlimited) matches the primary part specification. Contact finish thickness of 39.4µin (1.00µm) provides equivalent durability enhancement.

Both LEMO substitutes are suitable for direct replacement in applications where the primary part is unavailable, subject to mechanical fit verification with mating connectors.

Frequently Asked Questions (FAQ)

Q: What determines if FGG.1B.303.CLAD62 can replace JBXFD1G03MSSDSMR?

A: Substitution is valid when the following parameters match: 3-position plug configuration, male pins, solder cup termination, push-pull fastening, shielded construction, 12A current rating, gold contact finish, PEEK insert material, and UL94 V-0 flammability rating. Both LEMO parts meet these criteria.

Q: Are there voltage rating differences between the main part and substitutes?

A: The JBXFD1G03MSSDSMR specifies 600V voltage rating. The LEMO FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z do not list voltage ratings in the provided specifications. Applications requiring 600V operation should confirm voltage capability with the substitute part manufacturer before implementation.

Q: What is the difference between FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z?

A: Both parts are electrically and mechanically identical. The primary difference is the MSL (Moisture Sensitivity Level) designation: FGG.1B.303.CLAD62 lists MSL as Not Applicable, while FGG.1B.303.CLAD62Z specifies MSL 1 (Unlimited). For applications with moisture sensitivity requirements, FGG.1B.303.CLAD62Z is the appropriate selection.

Q: Do the substitute parts have different operating temperature ranges?

A: Yes. The JBXFD1G03MSSDSMR operates from -40°C to 125°C. Both LEMO substitutes operate from -55°C to 250°C, providing extended thermal capability for high-temperature applications.

Q: What is the difference in contact finish thickness?

A: The JBXFD1G03MSSDSMR has contact finish thickness of 19.7µin (0.50µm). Both LEMO substitutes have contact finish thickness of 39.4µin (1.00µm), providing doubled plating thickness for enhanced contact durability and wear resistance.

Q: Are all three parts RoHS3 compliant?

A: Yes. The JBXFD1G03MSSDSMR, FGG.1B.303.CLAD62, and FGG.1B.303.CLAD62Z are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

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

A: The LEMO FGG.1B.303.CLAD62 and FGG.1B.303.CLAD62Z specify cable opening of 0.205" to 0.244" (5.20mm to 6.20mm). The primary part does not list cable opening specifications. Cable diameter compatibility should be verified during mechanical integration.
