Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JBXFD2G16MWSDSMR are identified based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Connector type: Plug with male pins
• Position count: 16 positions
• Shell size insert designation: 316 (equivalent to size 2)
• Fastening mechanism: Push-pull
• Orientation: G
• Shell material: Brass
• Contact finish: Gold plating
• Shielding: Shielded construction
• Current rating: 6A
• Insert material: PEEK
• Flammability rating: UL94 V-0
• Compliance: ROHS3 compliant, REACH unaffected

Allowable Variations:

• Termination method: Main part uses unspecified termination; substitutes use solder cup termination
• Shell finish: Main part specifies chrome over nickel; substitutes specify chrome
• Ingress protection: Main part IP40; substitutes IP50
• Operating temperature range: Main part -40°C to 125°C; substitutes -55°C to 250°C
• Contact finish thickness: Main part 19.7µin; substitutes 39.4µin

The three LEMO FGG.2B.316 series connectors (CLAZ, CLAD52, CLAD92Z) are functionally equivalent to the JBXFD2G16MWSDSMR for applications where solder cup termination is acceptable and the extended temperature capability is beneficial or neutral.

Parameter Comparison

Engineering Selection Recommendations

JBXFD2G16MWSDSMR (Primary Part)

The JBXFD2G16MWSDSMR remains the specified component when the original termination method and exact operating temperature range (-40°C to 125°C) are required. This part is active and maintains full compliance with ROHS3 and REACH requirements.

FGG.2B.316.CLAZ

The FGG.2B.316.CLAZ is suitable as a substitute when solder cup termination is compatible with the application design. This LEMO connector provides extended operating temperature capability (-55°C to 250°C) and improved ingress protection (IP50). The part is active, ROHS3 compliant, and REACH unaffected. Cable opening specification is not provided for this variant.

FGG.2B.316.CLAD52

The FGG.2B.316.CLAD52 is suitable as a substitute when solder cup termination is compatible and cable opening range of 0.165" to 0.205" (4.20mm to 5.20mm) matches application requirements. This LEMO connector provides extended operating temperature capability and improved ingress protection. The part is active and maintains full compliance status.

FGG.2B.316.CLAD92Z

The FGG.2B.316.CLAD92Z is suitable as a substitute when solder cup termination is compatible and cable opening range of 0.323" to 0.362" (8.20mm to 9.20mm) matches application requirements. This LEMO connector provides extended operating temperature capability and improved ingress protection. The part is active, ROHS3 compliant, and REACH unaffected.

All substitute parts maintain the critical electrical parameters (6A current rating, gold-plated contacts, shielded construction) and mechanical compatibility (16 positions, push-pull fastening, PEEK inserts, UL94 V-0 rating) required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between the JBXFD2G16MWSDSMR and the LEMO FGG.2B.316 series substitutes?

A: The main differences are termination method (unspecified for JBXFD2G16MWSDSMR versus solder cup for LEMO parts), shell finish (chrome over nickel versus chrome), ingress protection rating (IP40 versus IP50), and operating temperature range (-40°C to 125°C versus -55°C to 250°C). All other critical parameters including connector type, position count, fastening mechanism, current rating, and contact finish are equivalent.

Q: Can the LEMO FGG.2B.316 series connectors be used as direct replacements in existing designs?

A: The LEMO connectors are functionally equivalent for applications where solder cup termination is acceptable. The extended temperature range and improved ingress protection are generally beneficial. However, the application design must accommodate solder cup termination rather than the original termination method.

Q: What is the significance of the different cable opening specifications among the LEMO variants?

A: Cable opening specifications determine the range of cable diameters that can be accommodated by each connector variant. FGG.2B.316.CLAD52 accepts cables 4.20mm to 5.20mm in diameter, while FGG.2B.316.CLAD92Z accepts cables 8.20mm to 9.20mm in diameter. Selection depends on the actual cable diameter used in the application. FGG.2B.316.CLAZ does not specify a cable opening range.

Q: Are all substitute parts compliant with the same regulatory standards as the main part?

A: Yes. All parts listed are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and carry the same HTSUS code (8536.69.4020). All parts maintain UL94 V-0 flammability rating.

Q: What is the difference in contact finish thickness between the main part and substitutes?

A: The JBXFD2G16MWSDSMR specifies 19.7µin (0.50µm) gold plating thickness, while the LEMO substitutes specify 39.4µin (1.00µm). The thicker plating on LEMO parts provides enhanced durability and corrosion resistance, which is generally advantageous for long-term reliability.

Q: Which substitute part should be selected if the application requires the smallest cable opening?

A: The FGG.2B.316.CLAD52 should be selected, as it accommodates cable diameters from 4.20mm to 5.20mm, the smallest range among the specified variants.

Q: Which substitute part should be selected if the application requires the largest cable opening?

A: The FGG.2B.316.CLAD92Z should be selected, as it accommodates cable diameters from 8.20mm to 9.20mm, the largest range among the specified variants.

Q: Is the voltage rating difference between the main part (730V) and substitutes (not specified) significant?

A: The voltage rating is specified only for the JBXFD2G16MWSDSMR at 730V. The LEMO substitutes do not provide voltage rating specifications in the available data. Applications requiring confirmation of voltage capability should contact the manufacturer directly.
