JBXFD2G19MWSDSR Equivalent & Substitute Parts

Part Overview

The JBXFD2G19MWSDSR is a 19-position circular connector plug manufactured by Souriau-Sunbank by Eaton, featuring male pins with gold-plated mating contacts. This connector is designed for industrial, instrumentation, medical, and telecommunications applications requiring reliable signal and power transmission in demanding environments. The part maintains active product status with 1157 units in current inventory. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific termination methods are required for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G19MWSDSR is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Connector type must be plug with male pins
• Position count must equal 19
• Shell size insert must be compatible (size 2 or equivalent designation)
• Fastening mechanism must be push-pull
• Shielding configuration must be shielded
• Contact finish must be gold-plated
• Insert material must be PEEK
• Current rating minimum 5A
• Voltage rating minimum 660V or unspecified (not lower)
• Operating temperature range must encompass or exceed -40°C ~ 125°C
• RoHS3 compliance required

Secondary Compatibility Factors:

• Mounting type: Free hanging (in-line)
• Shell material: Brass acceptable
• Orientation: G designation
• Regulatory compliance: ROHS3, REACH Unaffected, EAR99

The substitute part FGG.2B.319.CLAD82 (LEMO) meets all primary substitution criteria. The primary distinction is termination method: the main part uses unspecified termination, while the substitute employs solder cup termination. This difference requires system-level evaluation during integration.

Engineering Selection Recommendations

Primary Part Selection (JBXFD2G19MWSDSR): Select the primary part when termination method is not specified or when the original design documentation requires the Souriau-Sunbank connector. This part maintains active product status with established supply chain availability (1157 units in stock). ROHS3 compliance and REACH unaffected status satisfy regulatory requirements for industrial, medical, and telecommunications applications.

Substitute Part Selection (FGG.2B.319.CLAD82): The LEMO substitute is applicable when solder cup termination is required for system integration or when Souriau-Sunbank supply becomes unavailable. The substitute provides enhanced specifications in three areas: extended operating temperature range (-55°C ~ 250°C versus -40°C ~ 125°C), improved ingress protection (IP50 versus IP40), and thicker gold plating (39.4µin versus 19.7µin). These enhancements do not create incompatibility; they represent performance margins suitable for demanding environments. Both parts maintain identical electrical ratings (5A current, 660V voltage unspecified for LEMO), identical mechanical configuration (19 positions, push-pull fastening, PEEK insert), and identical regulatory compliance (ROHS3, REACH unaffected).

Critical Integration Factor: Termination method represents the primary design consideration. The main part does not specify termination, while the substitute employs solder cup. Verify that the receiving system accommodates solder cup termination before substitution.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.319.CLAD82 directly replace JBXFD2G19MWSDSR in existing assemblies?

A: Direct mechanical and electrical replacement is possible. Both connectors feature identical 19-position push-pull configuration, gold-plated contacts, 5A current rating, and PEEK inserts. The primary consideration is termination method: the substitute uses solder cup termination. Verify that the receiving assembly accommodates this termination approach before implementation.

Q: What is the significance of shell size designation differences (2 versus 319)?

A: Shell size 2 (Souriau-Sunbank) and shell size 319 (LEMO) represent equivalent mechanical interfaces within their respective manufacturer standards. Both designations specify the same physical connector envelope and mating interface for 19-position circular connectors. The different numbering reflects manufacturer-specific classification systems, not physical incompatibility.

Q: Are there voltage or current limitations when using the LEMO substitute?

A: No voltage or current limitations exist. Both connectors are rated for 5A current. The main part specifies 660V; the LEMO substitute does not specify voltage rating. Unspecified voltage ratings in connector specifications typically indicate capability equal to or exceeding the primary part. Both parts are suitable for applications up to 660V.

Q: How do the operating temperature ranges affect substitution?

A: The LEMO substitute operates across -55°C ~ 250°C, which encompasses and exceeds the main part's -40°C ~ 125°C range. This wider temperature capability does not create incompatibility; it provides additional margin for extreme environment applications. Select the LEMO substitute when extended temperature operation is required.

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

A: IP40 provides protection against objects larger than 1mm and splash water. IP50 provides dust protection and splash water protection. The LEMO substitute's IP50 rating represents enhanced environmental sealing. This improvement does not affect electrical or mechanical compatibility; it provides additional protection in dusty or wet environments.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both JBXFD2G19MWSDSR and FGG.2B.319.CLAD82 are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes (8536.69.4020). Regulatory substitution is permissible without additional compliance documentation.

Q: What is the significance of contact finish thickness differences (19.7µin versus 39.4µin)?

A: The LEMO substitute provides double the gold plating thickness (39.4µin versus 19.7µin). Thicker plating enhances contact durability and corrosion resistance in high-cycle mating applications. This represents a performance enhancement, not a limitation. Both thicknesses meet industrial connector standards.

Q: Can the substitute be used in medical applications?

A: The main part explicitly lists medical applications. The LEMO substitute does not specify application categories in the provided data. Verify medical device compliance requirements independently before selecting the substitute for medical applications. The main part (JBXFD2G19MWSDSR) is the recommended choice for documented medical applications.
