Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FHG.00.304.CLAD17Z are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Connector type: Plug with male pins
• Number of positions: 4
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shell material finish: Chrome-plated
• Contact finish: Gold-plated mating surfaces
• Ingress protection: IP50 or equivalent
• Insert material: Polyetheretherketone (PEEK)

Substitutes are grouped into two categories:

1. Manufacturer Recommended Substitute (Direct Replacement): FPG.00.304.CLAD17Z from LEMO maintains identical mechanical and electrical specifications with active product status.

2. Cross-Manufacturer Substitute (Functional Equivalent): W2CL0C-P04MCC0-2500 from ODU provides equivalent connector functionality with differences in shell size designation, shielding configuration, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

FPG.00.304.CLAD17Z (LEMO Recommended Substitute):

This part is the primary substitute for the obsolete FHG.00.304.CLAD17Z. Both connectors share identical mechanical specifications, electrical ratings, and operating parameters. The FPG.00.304.CLAD17Z maintains active product status, ensuring ongoing availability and manufacturer support. This substitute is suitable for direct replacement in applications where the original FHG.00.304.CLAD17Z was specified.

W2CL0C-P04MCC0-2500 (ODU Cross-Manufacturer Substitute):

This ODU MINI-SNAP® L series connector provides functional equivalence with the following considerations:

• Operating temperature range is limited to -40°C ~ 120°C, compared to the original -55°C ~ 250°C specification. This substitute is not suitable for applications requiring the full temperature range of the original connector.
• Current rating is 4A, exceeding the 2A requirement of the original connector.
• Shielding configuration differs: the ODU part is unshielded, while the original FHG.00.304.CLAD17Z is shielded. Applications requiring electromagnetic shielding must account for this difference.
• Shell size designation differs (0 versus 304), indicating different mechanical form factors.

Selection of the ODU substitute requires confirmation that the reduced operating temperature range and absence of shielding are compatible with the application requirements.

Frequently Asked Questions (FAQ)

Q: Can FPG.00.304.CLAD17Z be used as a direct replacement for FHG.00.304.CLAD17Z?

A: Yes. Both connectors are manufactured by LEMO and share identical specifications for connector type, number of positions, shell size, termination method, fastening type, shielding, current rating, operating temperature range, contact finish, and ingress protection. The FPG.00.304.CLAD17Z is the active product replacement for the obsolete FHG.00.304.CLAD17Z.

Q: What are the key differences between the LEMO FPG.00.304.CLAD17Z and the ODU W2CL0C-P04MCC0-2500?

A: The primary differences are: (1) Operating temperature range—LEMO supports -55°C ~ 250°C while ODU supports -40°C ~ 120°C; (2) Shielding—LEMO is shielded, ODU is unshielded; (3) Current rating—LEMO is 2A, ODU is 4A; (4) Shell size designation—LEMO uses 304, ODU uses 0; (5) Shell material—LEMO uses brass, ODU uses copper alloy.

Q: Is the ODU W2CL0C-P04MCC0-2500 suitable for applications requiring the full temperature range of the original connector?

A: No. The ODU connector operates only to -40°C ~ 120°C, which does not meet the -55°C ~ 250°C specification of the original FHG.00.304.CLAD17Z. Applications requiring operation at temperatures below -40°C or above 120°C must use the LEMO FPG.00.304.CLAD17Z substitute.

Q: Does the absence of shielding in the ODU W2CL0C-P04MCC0-2500 affect compatibility?

A: Shielding provides electromagnetic interference protection. Applications requiring EMI shielding must use the shielded LEMO FPG.00.304.CLAD17Z. The unshielded ODU connector is suitable only for applications where electromagnetic shielding is not a requirement.

Q: Are all three connectors compatible with solder cup termination?

A: Yes. The FHG.00.304.CLAD17Z, FPG.00.304.CLAD17Z, and W2CL0C-P04MCC0-2500 all use solder cup termination, allowing equivalent soldering processes and assembly methods.

Q: What compliance certifications apply to these connectors?

A: The FHG.00.304.CLAD17Z is ROHS3 compliant. All three connectors are classified under ECCN EAR99 and HTSUS 8536.69.4020. Compliance documentation for the FPG.00.304.CLAD17Z and W2CL0C-P04MCC0-2500 should be obtained from the respective manufacturers.
