Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JBXFD1A05MSSDSMR is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Plug with male pins
• Position count: 5 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding: Shielded configuration
• Current rating: 9A minimum
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass construction
• Insert material: PEEK
• Flammability rating: UL94 V-0

Allowable Variations:

• Shell size (1 vs. 305): Different physical dimensions permitted based on application requirements
• Shell finish: Chrome or chrome over nickel acceptable
• Operating temperature range: Extended ranges acceptable (-55°C to 250°C vs. -40°C to 125°C)
• Ingress protection: IP50 acceptable as upgrade from IP40
• Contact finish thickness: Variations from 19.7µin to 39.4µin acceptable
• Cable opening specifications: Variations permitted based on cable gauge requirements

All substitute parts listed maintain ROHS3 compliance, EAR99 classification, and identical HTSUS coding (8536.69.4020).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 and REACH regulations. Selection among substitute options should be based on the following factors:

Availability and Lead Time: FGG.1B.305.CLAD52 (LEMO) offers the highest inventory level at 16,988 units, providing optimal availability for immediate procurement requirements.

Temperature Performance: All LEMO substitute parts (FGG series) support extended operating temperature range of -55°C to 250°C, compared to the main part's -40°C to 125°C specification. This extended range is suitable for applications requiring broader thermal operating windows.

Ingress Protection Enhancement: All substitute parts provide IP50 dust protection rating, exceeding the main part's IP40 rating. This enhancement is applicable to environments with elevated particulate contamination risk.

Contact Finish Specifications: LEMO substitutes provide 39.4µin (1.00µm) contact finish thickness versus the main part's 19.7µin (0.50µm), offering increased durability for high-cycle mating applications.

Cable Opening Compatibility: Substitute parts offer varied cable opening specifications (3.10-4.20mm, 4.20-5.20mm, 7.20-7.60mm) to accommodate different cable gauges. Selection must align with specific cable diameter requirements.

Backshell Configuration: FGG.1B.305.CLAZ includes "No Collet" feature, distinguishing it from other substitutes with standard backshell configuration.

Frequently Asked Questions (FAQ)

Q: Can FGG.1B.305.CLAD52 directly replace JBXFD1A05MSSDSMR in existing assemblies?

A: Direct mechanical and electrical replacement is supported based on matching connector type (plug, male pins), position count (5), termination (solder cup), fastening (push-pull), and current rating (9A). Physical shell size differs (305 vs. 1), requiring verification of mechanical fit within the application enclosure or connector cavity.

Q: What is the significance of shell size designation (1 vs. 305)?

A: Shell size determines the overall physical dimensions of the connector body. Size 1 and size 305 are different form factors. Selection must be based on the mating receptacle or application mechanical constraints. These are not interchangeable without mechanical redesign.

Q: Are the LEMO FGG series connectors compatible with Souriau-Sunbank JBX series receptacles?

A: Compatibility between plug and receptacle requires matching shell size and orientation specifications. The main part uses shell size 1 with orientation A, while LEMO substitutes use shell size 305 with orientation G. Mechanical and electrical compatibility must be confirmed with mating receptacle specifications before implementation.

Q: What is the difference between FGG.1B.305.CLAD52 and FGG.1B.305.CLAD76?

A: Both parts are electrically and functionally equivalent. The primary difference is cable opening specification: CLAD52 accommodates 4.20-5.20mm cable diameter, while CLAD76 accommodates 7.20-7.60mm cable diameter. Selection depends on the cable gauge used in the application.

Q: Does FGG.1B.305.CLAZ "No Collet" feature affect substitution eligibility?

A: The "No Collet" feature represents a design variation in the backshell assembly. Electrical and mechanical connectivity remain equivalent. This variation may affect cable strain relief characteristics and should be evaluated against application requirements for cable retention and mechanical stress distribution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (FGG.1B.305.CLAD42, FGG.1B.305.CLAD52, FGG.1B.305.CLAD76, FGG.1B.305.CLAZ) maintain ROHS3 compliance status, matching the main part specification.

Q: What is the impact of extended operating temperature range on substitute selection?

A: LEMO substitute parts support -55°C to 250°C operating range versus the main part's -40°C to 125°C. Extended temperature capability does not restrict substitution in applications operating within the main part's original temperature window. For applications requiring extended temperature performance, LEMO substitutes provide additional operational margin.

Q: How does contact finish thickness affect connector performance?

A: Contact finish thickness (19.7µin vs. 39.4µin) influences contact durability and mating cycle life. Thicker plating (39.4µin) provides extended wear resistance in high-cycle mating applications. Both thicknesses maintain electrical performance within specified current and voltage ratings.

Q: Is voltage rating specification available for LEMO substitute parts?

A: Voltage rating is not specified in the provided data for LEMO FGG series substitutes. The main part specifies 660V rating. Voltage compatibility must be confirmed through LEMO technical documentation before implementation in high-voltage applications.

Q: What packaging format is used for substitute parts?

A: All LEMO substitute parts are supplied in bulk packaging, differing from the main part's unspecified packaging format. Bulk packaging may require reel or tape configuration verification for automated assembly processes.
