JBXFD2G16MWSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD2G16MWSDSR is a 16-position circular connector plug manufactured by Souriau-Sunbank by Eaton. This male pin connector features gold-plated mating contacts, chrome over nickel shell finish, and push-pull fastening. The connector is designed for industrial, instrumentation, medical, and telecommunications applications with an operating temperature range of -40°C to 125°C and a current rating of 6A at 730V.

The part is currently active in production with 767 units in stock. Substitute parts are necessary when alternative termination methods (solder cup versus free hanging), different operating temperature ranges, or specific cable opening requirements are required for system integration.

Fastening type: Push-Pull
Orientation: G
Shell material: Brass
Contact finish: Gold
Shielding: Shielded
Current rating: 6A
Insert material: PEEK

Engineering Selection Recommendations

JBXFD2G16MWSDSR (Primary Part): Use this configuration when free hanging (in-line) termination is required. This part is suitable for applications requiring direct cable integration without solder cup termination. The operating temperature range of -40°C to 125°C is appropriate for standard industrial and telecommunications environments. ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

FGG.2B.316.CLAZ (LEMO Substitute): Select this part when solder cup termination is required and cable opening specifications are not critical. This configuration provides extended operating temperature capability (-55°C to 250°C) and improved ingress protection (IP50). ROHS3 compliance and REACH unaffected status maintain regulatory requirements. Inventory availability is 1038 units.

FGG.2B.316.CLAD52 (LEMO Substitute): Use this part for solder cup termination with cable opening range of 0.165" to 0.205" (4.20mm to 5.20mm). This configuration is suitable for smaller diameter cable applications. Extended operating temperature range (-55°C to 250°C) and IP50 ingress protection are provided. ROHS3 compliance is maintained. Inventory availability is 1008 units.

FGG.2B.316.CLAD92Z (LEMO Substitute): Select this part for solder cup termination with larger cable opening range of 0.323" to 0.362" (8.20mm to 9.20mm). This configuration accommodates larger diameter cables. Extended operating temperature range (-55°C to 250°C) and IP50 ingress protection are provided. ROHS3 compliance and MSL 1 rating are maintained. Inventory availability is 732 units.

Frequently Asked Questions (FAQ)

Q: Can LEMO FGG.2B.316 series parts directly replace the Souriau-Sunbank JBXFD2G16MWSDSR?

A: Direct mechanical and electrical replacement is possible only when termination method differences are acceptable. The LEMO parts use solder cup termination while the JBXFD2G16MWSDSR uses free hanging termination. All critical electrical parameters (16 positions, 6A current rating, gold contacts, shielding, PEEK insert) are identical. System integration must account for the termination method change.

Q: What is the significance of the different cable opening specifications in FGG.2B.316.CLAD52 and FGG.2B.316.CLAD92Z?

A: Cable opening specifications determine the range of cable diameters that can be accommodated by the solder cup termination. FGG.2B.316.CLAD52 accepts cables with diameters from 0.165" to 0.205" (4.20mm to 5.20mm), while FGG.2B.316.CLAD92Z accepts cables from 0.323" to 0.362" (8.20mm to 9.20mm). Selection depends on the actual cable diameter used in the application.

Q: Are the LEMO substitute parts suitable for the same temperature range as the original JBXFD2G16MWSDSR?

A: The LEMO parts support an extended operating temperature range of -55°C to 250°C compared to the JBXFD2G16MWSDSR range of -40°C to 125°C. This means LEMO parts can operate at lower and higher temperatures. For applications within the original -40°C to 125°C range, both parts are suitable.

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

A: The JBXFD2G16MWSDSR has a contact finish thickness of 19.7µin (0.50µm), while all LEMO substitute parts have 39.4µin (1.00µm). The thicker gold plating on LEMO contacts provides enhanced durability and wear resistance for repeated mating cycles.

Q: Do all parts maintain the same compliance certifications?

A: Yes. The JBXFD2G16MWSDSR and all three LEMO substitute parts are ROHS3 compliant and REACH unaffected. All parts carry UL94 V-0 material flammability rating. Regulatory compliance is maintained across all options.

Q: What is the difference between IP40 and IP50 ingress protection ratings?

A: The JBXFD2G16MWSDSR provides IP40 protection (protected against solid objects larger than 1mm and water splashes). The LEMO substitute parts provide IP50 protection (dust protected and protected against water jets). IP50 offers enhanced environmental protection suitable for more demanding industrial conditions.

Q: Can the shell finish difference (Chrome over Nickel vs. Chrome) affect performance?

A: Both finishes provide corrosion resistance and electrical conductivity. The chrome over nickel finish on the JBXFD2G16MWSDSR provides additional corrosion protection through the nickel undercoat. The chrome-only finish on LEMO parts is suitable for standard industrial environments. Selection depends on specific environmental exposure requirements.
