Substitute Part Grouping Explanation

Substitution of the JBXFD1G08MCSDSR is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

Connector type: Plug with male pins
Position count: 8 positions
Termination method: Crimp
Fastening mechanism: Push-Pull
Contact finish: Gold plating on mating surfaces
Shielding: Shielded configuration
Current capacity: 5A minimum
Material compliance: UL94 V-0 flammability rating

Engineering Selection Recommendations

All substitute parts listed (FGG.1B.308.CYCD52, FGG.1B.308.CYCD62, FGG.1B.308.CYCD72) are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory compliance profile of the JBXFD1G08MCSDSR.

Selection Basis:

The LEMO FGG.1B.308 series substitutes maintain electrical compatibility through identical 5A current rating, 8-position configuration, crimp termination, and gold-plated contacts. All parts share UL94 V-0 flammability certification and PEEK insert material.

Cable Opening Selection:

Choose the substitute part based on cable diameter requirements:

FGG.1B.308.CYCD52: For cables 4.20mm to 5.20mm diameter
FGG.1B.308.CYCD62: For cables 5.20mm to 6.20mm diameter
FGG.1B.308.CYCD72: For cables 6.20mm to 7.20mm diameter

Environmental Considerations:

LEMO substitutes provide extended operating temperature range (-55°C to 250°C) compared to the primary part (-40°C to 125°C) and higher ingress protection rating (IP50 versus IP40), offering enhanced performance in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.308.CYCD52, FGG.1B.308.CYCD62, and FGG.1B.308.CYCD72 be used interchangeably with JBXFD1G08MCSDSR?

A: These parts are mechanically and electrically compatible substitutes. Selection depends on cable opening diameter. The JBXFD1G08MCSDSR does not specify cable opening, so the appropriate LEMO variant must be selected based on the actual cable gauge used in the application.

Q: What is the difference between the three LEMO substitute options?

A: The three FGG.1B.308 variants differ only in cable opening diameter range. FGG.1B.308.CYCD52 accommodates 4.20-5.20mm cables, CYCD62 accommodates 5.20-6.20mm cables, and CYCD72 accommodates 6.20-7.20mm cables. All other electrical and mechanical specifications are identical.

Q: Are the LEMO substitutes compliant with the same regulatory standards?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification, matching the primary part's compliance profile.

Q: Do the operating temperature ranges differ between the primary part and substitutes?

A: Yes. The JBXFD1G08MCSDSR operates from -40°C to 125°C, while LEMO FGG.1B.308 series parts operate from -55°C to 250°C. The LEMO parts provide extended temperature capability.

Q: What is the ingress protection difference?

A: The JBXFD1G08MCSDSR provides IP40 protection, while LEMO substitutes provide IP50 dust protection, offering enhanced environmental sealing.

Q: Are crimp termination tools compatible between the primary part and substitutes?

A: Both the primary part and all substitutes use crimp termination. Compatibility depends on the specific crimp tool specifications, which are not provided in the available parameters.

Q: What inventory levels are available for each part?

A: JBXFD1G08MCSDSR: 831 pieces; FGG.1B.308.CYCD52: 975 pieces; FGG.1B.308.CYCD62: 991 pieces; FGG.1B.308.CYCD72: 703 pieces.
