JBXFD1A08MCSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD1A08MCSDSMR is an 8-position circular connector plug with male pins manufactured by Souriau-Sunbank by Eaton. This shielded connector features crimp termination, push-pull fastening, and gold-plated mating contacts rated for 5A at 600V. The connector is designed for free-hanging in-line mounting in industrial, instrumentation, medical, and telecommunications applications. The product maintains active status with 936 units in current inventory. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when cable opening specifications require different configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1A08MCSDSMR is determined by the following critical parameters: 8-position configuration, male pin connector type, crimp termination, push-pull fastening mechanism, shielded design, 5A current rating, gold-plated mating contacts, PEEK insert material, and UL94 V-0 flammability compliance.

The three LEMO FGG.1B.308.CYCD series connectors (FGG.1B.308.CYCD52, FGG.1B.308.CYCD62, FGG.1B.308.CYCD72) satisfy all core substitution criteria. These parts are differentiated by cable opening specifications: CYCD52 accommodates 0.165" to 0.205" (4.20mm to 5.20mm), CYCD62 accommodates 0.205" to 0.244" (5.20mm to 6.20mm), and CYCD72 accommodates 0.244" to 0.283" (6.20mm to 7.20mm). Selection among these substitutes depends on the specific cable diameter requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and comply with ROHS3 and REACH requirements. The LEMO FGG.1B.308.CYCD series connectors are certified to UL94 V-0 flammability standards, matching the primary part specification.

Selection among the three LEMO substitutes is determined by cable diameter compatibility. The CYCD52 variant is suitable for cables with outer diameters between 4.20mm and 5.20mm. The CYCD62 variant accommodates cables between 5.20mm and 6.20mm. The CYCD72 variant is specified for cables between 6.20mm and 7.20mm. Cable opening specifications must align with the actual cable diameter used in the application to ensure proper connector seating and strain relief function.

The LEMO substitutes operate across a wider temperature range (-55°C to 250°C) compared to the JBXFD1A08MCSDSMR (-40°C to 125°C), providing extended thermal capability for demanding environments. Contact finish thickness on LEMO parts is 39.4µin (1.00µm) versus 19.7µin (0.50µm) on the primary part, offering enhanced contact durability.

Frequently Asked Questions (FAQ)

Q: What determines whether an FGG.1B.308.CYCD series connector can substitute for the JBXFD1A08MCSDSMR?

A: Substitution is valid when the cable opening specification of the selected LEMO variant matches the outer diameter of the cable assembly. All three CYCD variants share identical electrical and mechanical characteristics (8 positions, 5A rating, crimp termination, push-pull fastening, gold-plated contacts, PEEK inserts, UL94 V-0 compliance). The only differentiator is cable opening range.

Q: How do I select between CYCD52, CYCD62, and CYCD72?

A: Measure the outer diameter of your cable assembly. If the cable diameter falls between 4.20mm and 5.20mm, use CYCD52. For diameters between 5.20mm and 6.20mm, use CYCD62. For diameters between 6.20mm and 7.20mm, use CYCD72. Selecting the correct variant ensures proper strain relief and connector retention.

Q: Are there electrical compatibility differences between the primary part and substitutes?

A: No. All parts are rated for 5A current, feature gold-plated mating contacts, crimp termination, push-pull fastening, and shielded design. Electrical performance is equivalent across all four connectors.

Q: What is the difference in contact finish thickness?

A: The JBXFD1A08MCSDSMR has 19.7µin (0.50µm) gold plating on mating contacts. The LEMO FGG.1B.308.CYCD series has 39.4µin (1.00µm) gold plating. Thicker plating on LEMO parts provides enhanced contact durability and wear resistance in high-cycle mating applications.

Q: Can I use a substitute part in an application with operating temperatures below -40°C or above 125°C?

A: The LEMO FGG.1B.308.CYCD series is rated for -55°C to 250°C operation, extending the usable temperature range beyond the JBXFD1A08MCSDSMR specification of -40°C to 125°C. Substitutes are suitable for applications requiring extended temperature performance.

Q: Are all parts RoHS and REACH compliant?

A: Yes. The JBXFD1A08MCSDSMR and all three LEMO FGG.1B.308.CYCD variants are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for each part?

A: JBXFD1A08MCSDSMR has 936 units in stock. FGG.1B.308.CYCD52 has 975 units. FGG.1B.308.CYCD62 has 991 units. FGG.1B.308.CYCD72 has 703 units. All parts are listed as new original stock.
