JBXFD1A03MCSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD1A03MCSDSMR is a 3-position circular connector plug manufactured by Souriau-Sunbank by Eaton, featuring male pins with crimp termination and gold-plated mating contacts. This connector is classified as an active product with 913 units in current inventory stock. The device operates across industrial, instrumentation, medical, and telecommunications applications with a rated capacity of 12A at 600V and an operating temperature range of -40°C to 125°C.

Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable, when inventory constraints exist, or when supply chain diversification is required for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1A03MCSDSMR is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Plug with male pins
• Number of positions: 3
• Termination method: Crimp
• Fastening mechanism: Push-Pull
• Shell material: Brass
• Contact finish at mating surface: Gold
• Shielding configuration: Shielded
• Current rating: 12A
• Mounting configuration: Free Hanging (In-Line)
• Insert material: Polyetheretherketone (PEEK)
• Regulatory compliance: ROHS3 Compliant

The substitute part FGG.1B.303.CYCD62 manufactured by LEMO satisfies all mandatory matching parameters. Both connectors are 3-position male plug connectors with crimp termination, push-pull fastening, brass shells with gold-plated mating contacts, shielded construction, 12A current rating, free-hanging mounting, PEEK inserts, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the JBXFD1A03MCSDSMR and FGG.1B.303.CYCD62 are active products with current inventory availability and full ROHS3 compliance. Selection between these parts is based on application-specific requirements and environmental constraints.

JBXFD1A03MCSDSMR Selection Criteria:

• Applications requiring explicit 600V voltage rating specification
• Operating environments limited to -40°C to 125°C temperature range
• Designs requiring boot adapter feature integration
• Specifications requiring 19.7µin gold contact finish thickness

FGG.1B.303.CYCD62 Selection Criteria:

• Applications requiring extended operating temperature range (-55°C to 250°C)
• Environments requiring IP50 dust protection versus IP40
• Designs where thicker gold contact finish (39.4µin) provides enhanced durability
• Applications where voltage rating is not a specified constraint
• Cable opening specifications of 0.205" to 0.244" (5.20mm to 6.20mm) are compatible

Both connectors maintain identical core electrical and mechanical specifications for 3-position male plug crimp connectors with 12A current capacity, push-pull fastening, shielded brass construction with gold-plated contacts, PEEK inserts, and free-hanging mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.303.CYCD62 directly replace JBXFD1A03MCSDSMR in all applications?

A: Direct substitution is valid when the application does not require the explicit 600V voltage rating specification or the boot adapter feature. The FGG.1B.303.CYCD62 provides superior environmental protection (IP50 versus IP40) and extended temperature range (-55°C to 250°C versus -40°C to 125°C). Verify that the cable opening specification of 0.205" to 0.244" is compatible with your cable assembly.

Q: What are the differences in contact finish specifications?

A: The JBXFD1A03MCSDSMR features 19.7µin (0.50µm) gold plating on mating contacts, while the FGG.1B.303.CYCD62 features 39.4µin (1.00µm) gold plating. The thicker gold finish on the LEMO connector provides increased wear resistance and extended contact life in high-cycle mating applications.

Q: Are both connectors suitable for medical applications?

A: The JBXFD1A03MCSDSMR is explicitly listed for medical applications. The FGG.1B.303.CYCD62 does not specify medical applications in the provided data. Verify medical device compliance requirements independently before substitution in medical applications.

Q: What is the difference in shell finish specifications?

A: The JBXFD1A03MCSDSMR features chrome over nickel plating on the brass shell, while the FGG.1B.303.CYCD62 features chrome plating. Both finishes provide corrosion resistance; the nickel underplate in the Souriau connector provides additional corrosion protection in harsh environments.

Q: Are both connectors RoHS compliant?

A: Both connectors are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial, instrumentation, and telecommunications applications.

Q: What packaging options are available?

A: The JBXFD1A03MCSDSMR is available in standard packaging with 913 units in current inventory. The FGG.1B.303.CYCD62 is available in bulk packaging with 844 units in current inventory.
