Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD2G19MWSDSMR is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 19
• Fastening Type: Push-Pull
• Shielding: Shielded
• Contact Finish - Mating: Gold
• Insert Material: Polyetheretherketone (PEEK)
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Shell Size - Insert: Equivalent circular connector sizing (2 or 319 designations represent compatible form factors)
• Current Rating: Equal or greater (5A minimum)
• Operating Temperature: Extended range acceptable if minimum -40°C and maximum ≥125°C are met
• Ingress Protection: Equal or greater (IP40 or higher)
• Termination Type: Solder Cup acceptable as alternative to unspecified termination
• Shell Finish: Chrome or Chrome over Nickel both acceptable for brass shells

The FGG.2B.319.CLAD82 manufactured by LEMO meets all mandatory matching parameters and operates within allowable variations for substitute classification.

Engineering Selection Recommendations

Primary Selection: JBXFD2G19MWSDSMR

The JBXFD2G19MWSDSMR remains the primary choice when the original specification is required. This connector is Active status with 859 units in stock, ROHS3 compliant, and rated for 660V operation. The unspecified termination type provides flexibility for application-specific wiring methods.

Substitute Selection: FGG.2B.319.CLAD82

The FGG.2B.319.CLAD82 is a qualified substitute when supply constraints affect the primary part. This LEMO connector is Active status with 1082 units in stock and ROHS3 compliant. Key advantages include extended operating temperature range (-55°C ~ 250°C) and enhanced ingress protection (IP50 versus IP40). The solder cup termination is a defined alternative to the unspecified termination of the primary part. Both connectors carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, confirming regulatory equivalence.

Selection Criteria:

Use FGG.2B.319.CLAD82 when:

• Extended temperature operation below -40°C or above 125°C is required
• Enhanced dust protection (IP50) is specified
• Solder cup termination is compatible with assembly process
• Supply availability of primary part is constrained

Verify mechanical fit and cable opening compatibility (FGG.2B.319.CLAD82 specifies 0.283" ~ 0.323" / 7.20mm ~ 8.20mm) with your application before final selection.

Frequently Asked Questions (FAQ)

Q: Can FGG.2B.319.CLAD82 be used as a direct replacement for JBXFD2G19MWSDSMR?

A: Yes, within the constraints of termination method. Both connectors are 19-position male plug connectors with identical push-pull fastening, shielding, gold contact finish, and PEEK inserts. The primary difference is termination type: the LEMO part specifies solder cup termination while the Souriau-Sunbank part does not specify termination. Confirm your application uses or can accommodate solder cup termination.

Q: What is the difference in shell finish between these connectors?

A: The JBXFD2G19MWSDSMR uses Chrome over Nickel plating on a brass shell. The FGG.2B.319.CLAD82 uses Chrome plating on a brass shell. Both finishes provide corrosion resistance and are suitable for industrial applications. Chrome over Nickel offers additional corrosion protection in harsh environments.

Q: Are there voltage rating differences?

A: The JBXFD2G19MWSDSMR is rated for 660V. The FGG.2B.319.CLAD82 does not specify a voltage rating in the provided data. For applications requiring confirmed 660V operation, verify the LEMO part's voltage capability through the manufacturer before substitution.

Q: What is the significance of the different ingress protection ratings?

A: The JBXFD2G19MWSDSMR is rated IP40 (protected against solid objects larger than 1mm and water splash). The FGG.2B.319.CLAD82 is rated IP50 (dust protected and water spray resistant). IP50 provides enhanced protection in dusty or wet environments. Both ratings are suitable for industrial and instrumentation applications.

Q: Can I use the LEMO connector in temperature extremes?

A: The FGG.2B.319.CLAD82 operates from -55°C to 250°C, compared to the Souriau-Sunbank part's -40°C to 125°C range. The LEMO connector is suitable for cryogenic applications (below -40°C) and high-temperature environments (above 125°C). The primary part is limited to the narrower range specified.

Q: What is the cable opening specification for the LEMO connector?

A: The FGG.2B.319.CLAD82 accepts cable diameters of 0.283" to 0.323" (7.20mm to 8.20mm). Verify your cable diameter falls within this range before selecting this substitute. The primary part does not specify cable opening dimensions.

Q: Are both connectors RoHS compliant?

A: Yes. Both the JBXFD2G19MWSDSMR and FGG.2B.319.CLAD82 are ROHS3 compliant and REACH unaffected, confirming suitability for regulated markets and applications with environmental restrictions.

Q: What is the contact finish thickness difference?

A: The JBXFD2G19MWSDSMR specifies 19.7µin (0.50µm) gold plating on mating contacts. The FGG.2B.319.CLAD82 specifies 39.4µin (1.00µm) gold plating. The LEMO part provides double the gold plating thickness, offering enhanced wear resistance and contact durability in high-cycle mating applications.
