Substitute Categories:

Category A - Male Pin Plugs (Direct Functional Equivalents): FGG.1B.304.CLAD62 and FGG.1B.304.CLAD72 (LEMO manufacturer) are 4-position male pin solder cup plugs with identical connector type, termination, fastening, and contact finish specifications. These parts maintain the same electrical performance envelope and material compliance requirements.

Category B - Mixed Contact Configuration (Functional Alternatives): FFA.1S.304.CLAC52 and FFA.1S.304.CLAC62 (LEMO manufacturer) are 4-position solder cup plugs with female sockets and male pins configuration. While the contact arrangement differs from the main part, these connectors maintain equivalent electrical ratings, termination method, fastening type, and material specifications.

Category C - Limited Data Availability: FGG.1B.304.CLAD52Z (PEI-Genesis manufacturer) is listed as a 4-position circular connector with limited detailed specification data provided in the source documentation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Highest Compatibility):

FGG.1B.304.CLAD62 and FGG.1B.304.CLAD72 are the preferred substitute options. Both parts are manufactured by LEMO and maintain identical connector type (male pins), termination method (solder cup), fastening mechanism (push-pull), and electrical specifications (10A current rating, gold contact finish). Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability certification. The primary difference is cable opening specification: FGG.1B.304.CLAD62 accommodates 0.205" ~ 0.244" (5.20mm ~ 6.20mm) cable diameter, while FGG.1B.304.CLAD72 accommodates 0.244" ~ 0.283" (6.20mm ~ 7.20mm). Selection between these two depends on cable gauge requirements.

For Alternative Substitution (Functional Equivalence with Configuration Difference):

FFA.1S.304.CLAC52 and FFA.1S.304.CLAC62 are LEMO-manufactured alternatives featuring mixed contact configuration (female sockets and male pins) rather than male pins only. These parts maintain equivalent electrical performance (10A current rating, gold contact finish), termination method (solder cup), fastening type (push-pull), and compliance certifications (ROHS3, REACH unaffected, UL94 V-0). Cable opening specifications differ: FFA.1S.304.CLAC52 accommodates 0.165" ~ 0.205" (4.20mm ~ 5.20mm), while FFA.1S.304.CLAC62 accommodates 0.224" ~ 0.244" (5.70mm ~ 6.20mm). These parts are suitable only when the mixed contact configuration is compatible with the application circuit design.

Regarding FGG.1B.304.CLAD52Z:

This PEI-Genesis part is listed as a substitute but lacks sufficient detailed specification data in the provided documentation to establish complete parameter equivalence. Selection of this part requires verification of undocumented specifications against application requirements.

Temperature Operating Range Consideration:

All substitute parts (LEMO and PEI-Genesis) support extended operating temperature range (-55°C ~ 250°C) compared to the main part (-40°C ~ 125°C). This represents an advantage for applications requiring broader thermal performance.

Ingress Protection Consideration:

All substitute parts provide IP50 (dust protected) rating compared to the main part's IP40 rating, representing improved environmental protection capability.

Frequently Asked Questions (FAQ)

Q1: Can FGG.1B.304.CLAD62 directly replace JBXFD1A04MSSDSR in all applications?

FGG.1B.304.CLAD62 maintains equivalent electrical specifications (10A current rating, 900V design envelope), identical connector type (male pins), termination method (solder cup), and fastening mechanism (push-pull). Both parts are ROHS3 compliant and UL94 V-0 rated. The primary consideration is cable opening specification: FGG.1B.304.CLAD62 accommodates 5.20mm ~ 6.20mm cable diameter. Substitution is valid when cable gauge falls within this range.

Q2: What is the difference between FGG.1B.304.CLAD62 and FGG.1B.304.CLAD72?

Both parts are LEMO 4-position male pin solder cup plugs with identical electrical and material specifications. The difference is cable opening accommodation: FGG.1B.304.CLAD62 accepts 0.205" ~ 0.244" (5.20mm ~ 6.20mm) cable diameter, while FGG.1B.304.CLAD72 accepts 0.244" ~ 0.283" (6.20mm ~ 7.20mm). Selection depends on cable gauge requirements for the application.

Q3: Why are FFA.1S.304.CLAC52 and FFA.1S.304.CLAC62 listed as substitutes when they have different contact configurations?

FFA series parts feature female sockets and male pins configuration rather than male pins only. While the contact arrangement differs, these parts maintain equivalent electrical performance (10A current rating, gold contact finish), termination method (solder cup), fastening type (push-pull), and compliance certifications. These parts are functional alternatives when the mixed contact configuration is compatible with the application circuit design.

Q4: What is the significance of the cable opening specifications listed for substitute parts?

Cable opening specifications define the range of cable diameters that can be accommodated by the solder cup termination. Selection of a substitute part requires verification that the cable gauge used in the application falls within the specified cable opening range. Mismatched cable diameter may result in improper termination or mechanical stress.

Q5: Do all substitute parts meet the same compliance requirements as JBXFD1A04MSSDSR?

All listed substitute parts (FGG.1B.304.CLAD62, FGG.1B.304.CLAD72, FFA.1S.304.CLAC52, FFA.1S.304.CLAC62) are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability certification. FGG.1B.304.CLAD52Z compliance status is not specified in the provided documentation.

Q6: What is the difference in operating temperature range between the main part and substitutes?

JBXFD1A04MSSDSR operates from -40°C ~ 125°C. All LEMO substitute parts (FGG and FFA series) operate from -55°C ~ 250°C, providing extended thermal performance capability. This represents an advantage for applications requiring broader temperature operation.

Q7: How does ingress protection rating differ between the main part and substitutes?

JBXFD1A04MSSDSR provides IP40 ingress protection. All LEMO substitute parts provide IP50 (dust protected) rating, representing improved environmental sealing capability.

Q8: Are there inventory considerations when selecting substitute parts?

Current inventory levels are: JBXFD1A04MSSDSR (1119 units), FGG.1B.304.CLAD62 (866 units), FGG.1B.304.CLAD72 (977 units), FFA.1S.304.CLAC52 (1093 units), FFA.1S.304.CLAC62 (862 units), and FGG.1B.304.CLAD52Z (1068 units). All parts are in active production status with adequate stock availability.

Q9: What is the contact finish thickness difference between the main part and FGG series substitutes?

JBXFD1A04MSSDSR specifies gold contact finish thickness of 19.7µin (0.50µm). FGG.1B.304.CLAD62 and FGG.1B.304.CLAD72 specify 39.4µin (1.00µm) gold contact finish thickness, representing doubled plating thickness for enhanced durability.

Q10: Can FGG.1B.304.CLAD52Z be used as a substitute without additional verification?

FGG.1B.304.CLAD52Z is listed as a substitute but lacks detailed specification data in the provided documentation. Complete parameter equivalence cannot be established from available information. Use of this part requires independent verification of undocumented specifications against application requirements before implementation.
