JBXFD1G08MCSDSMR Equivalent & Substitute Parts

Part Overview

The JBXFD1G08MCSDSMR 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 841 pieces in current inventory. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application-specific cable opening requirements necessitate alternative models.

Substitute Part Grouping Explanation

Substitute parts for the JBXFD1G08MCSDSMR are identified based on strict equivalence of the following electrical and mechanical parameters:

Core Equivalence Criteria:

• Connector type: Plug with male pins
• Position count: 8 positions
• Termination method: Crimp
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Current rating: 5A
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass construction
• Insert material: Polyetheretherketone (PEEK)
• Mounting configuration: Free hanging in-line
• Regulatory compliance: ROHS3 compliant, REACH unaffected, EAR99 classification

The three LEMO FGG.1B.308 series connectors (CYCD52, CYCD62, CYCD72) satisfy all core equivalence criteria. These parts differ only in cable opening specifications, which accommodate different cable jacket diameters while maintaining identical electrical and mechanical interface characteristics. Selection among substitute parts is determined by cable opening requirements specific to the application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. The LEMO FGG.1B.308 series connectors provide equivalent electrical performance at the 5A current rating with identical crimp termination and push-pull fastening mechanisms.

Selection Basis:

The primary differentiator among substitute options is cable opening specification. Selection of FGG.1B.308.CYCD52, FGG.1B.308.CYCD62, or FGG.1B.308.CYCD72 is determined by the cable jacket outer diameter of the application:

• FGG.1B.308.CYCD52: Cable opening 0.165" ~ 0.205" (4.20mm ~ 5.20mm)
• FGG.1B.308.CYCD62: Cable opening 0.205" ~ 0.244" (5.20mm ~ 6.20mm)
• FGG.1B.308.CYCD72: Cable opening 0.244" ~ 0.283" (6.20mm ~ 7.20mm)

The LEMO substitute parts offer extended operating temperature range (-55°C ~ 250°C) compared to the JBXFD1G08MCSDSMR (-40°C ~ 125°C) and improved ingress protection rating (IP50 versus IP40). Contact finish thickness on LEMO parts is 39.4µin (1.00µm) compared to 19.7µin (0.50µm) on the Souriau-Sunbank part, providing enhanced contact durability.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the JBXFD1G08MCSDSMR?

A: Substitution is based on matching connector type (plug with male pins), position count (8), termination method (crimp), fastening mechanism (push-pull), shielding configuration (shielded), current rating (5A), contact finish (gold), shell material (brass), insert material (PEEK), and mounting type (free hanging in-line). All three LEMO FGG.1B.308 series parts meet these criteria.

Q: How do I select between the three LEMO substitute options?

A: Selection is determined by cable jacket outer diameter. Measure the cable diameter and select the part with the corresponding cable opening range: CYCD52 for 4.20-5.20mm, CYCD62 for 5.20-6.20mm, or CYCD72 for 6.20-7.20mm cables.

Q: Are the LEMO substitutes electrically equivalent?

A: Yes. All substitute parts carry identical 5A current rating, gold-plated mating contacts, crimp termination, and push-pull fastening. Electrical performance is equivalent across all options.

Q: What is the difference in operating temperature range?

A: The JBXFD1G08MCSDSMR operates from -40°C to 125°C. The LEMO FGG.1B.308 series operates from -55°C to 250°C, providing extended temperature capability for applications requiring broader thermal performance.

Q: Do all parts meet the same regulatory requirements?

A: Yes. The JBXFD1G08MCSDSMR and all three LEMO substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference in ingress protection rating?

A: The JBXFD1G08MCSDSMR has IP40 rating. The LEMO FGG.1B.308 series has IP50 rating (dust protected), providing enhanced environmental sealing.

Q: Is the contact finish thickness difference significant?

A: The LEMO parts have 39.4µin (1.00µm) gold plating compared to 19.7µin (0.50µm) on the Souriau-Sunbank part. The thicker plating on LEMO connectors provides extended contact life and improved wear resistance in high-cycle mating applications.

Q: Can I use these parts interchangeably in existing designs?

A: Interchangeability depends on cable opening requirements. The connector interfaces are mechanically and electrically equivalent, but the cable opening must match the cable jacket diameter used in the application. Verify cable diameter before selecting a substitute part.
