Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD1A03MSSDSMR are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Connector type classification (Plug, Male Pins)
• Position count (3 positions)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Current capacity (12A minimum)
• Shielding configuration (Shielded)
• Contact finish material (Gold plating)
• Insert material (PEEK)
• Regulatory compliance (ROHS3 Compliant, REACH Unaffected)

The FGG.1B.303.CLAD62 manufactured by LEMO meets all core compatibility criteria. Both connectors share identical functional specifications for connector type, position count, termination, fastening, current rating, shielding, contact finish, and insert material. Both are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

Both the JBXFD1A03MSSDSMR and FGG.1B.303.CLAD62 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts is determined by application-specific requirements:

JBXFD1A03MSSDSMR (Souriau-Sunbank by Eaton) is suitable for applications requiring the specified operating temperature range of -40°C to 125°C and IP40 ingress protection classification.

FGG.1B.303.CLAD62 (LEMO) is suitable for applications requiring extended operating temperature range (-55°C to 250°C), enhanced ingress protection (IP50), or increased contact finish thickness (39.4µin versus 19.7µin). The LEMO part provides superior environmental protection and thermal performance.

Both parts maintain identical electrical specifications (12A current rating, shielded configuration, gold-plated contacts) and mechanical compatibility (3-position, push-pull fastening, solder cup termination, PEEK insert).

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.303.CLAD62 directly replace JBXFD1A03MSSDSMR in existing designs?

A: Yes, within the specified electrical and mechanical parameters. Both connectors share identical connector type, position count, termination method, fastening mechanism, current rating, and contact finish. Physical dimensions and mating interface compatibility must be verified for specific mechanical integration.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (JBXFD1A03MSSDSMR: -40°C to 125°C; FGG.1B.303.CLAD62: -55°C to 250°C), ingress protection rating (IP40 versus IP50), and contact finish thickness (19.7µin versus 39.4µin). The LEMO part provides enhanced environmental and thermal performance.

Q: Are both parts compliant with current regulations?

A: Yes. Both JBXFD1A03MSSDSMR and FGG.1B.303.CLAD62 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial, instrumentation, medical, and telecommunications applications.

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

A: The FGG.1B.303.CLAD62 features 39.4µin (1.00µm) gold plating compared to 19.7µin (0.50µm) on the JBXFD1A03MSSDSMR. Increased plating thickness provides enhanced durability and corrosion resistance, particularly beneficial in high-cycle mating environments or harsh operating conditions.

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

A: The FGG.1B.303.CLAD62 supports operating temperatures up to 250°C, compared to 125°C maximum for the JBXFD1A03MSSDSMR. For applications exceeding 125°C, the LEMO part is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The JBXFD1A03MSSDSMR is available in standard packaging with 760 units in stock. The FGG.1B.303.CLAD62 is supplied in bulk packaging with 907 units in stock. Packaging format should be confirmed based on procurement requirements.
