LEMO FHG.00.303.CLAD35 Circular Connector Plug – Equivalent & Substitute Parts

Part Overview

The LEMO FHG.00.303.CLAD35 is a 3-position circular connector plug with male pins, solder cup termination, and gold-plated contacts. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and legacy equipment support. The connector features a push-pull fastening mechanism, shielded design, and operates across an extended temperature range of -55°C to 250°C, suitable for demanding industrial and aerospace applications.

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.00.303.CLAD35 is determined by the following critical parameters:

Connector Type & Position Count: Plug configuration with 3 male pins
Shell Size: 303 insert designation
Termination Method: Solder cup for direct wire attachment
Fastening Mechanism: Push-pull coupling
Contact Material & Finish: Gold-plated mating surfaces for signal integrity
Shielding: Electromagnetic shielding requirement
Current & Temperature Ratings: Minimum 3A capacity and -55°C to 250°C operating range

Two substitute parts meet these criteria:

FPG.00.303.CLAD35 (LEMO) – Direct manufacturer equivalent with identical electrical and mechanical specifications. Product status is active, ensuring continued availability and support.

W1CL0C-P03MCC0-2500 (ODU) – Cross-manufacturer alternative from ODU MINI-SNAP® L series. Maintains core functional compatibility with 3-position male pin configuration, solder cup termination, and push-pull fastening. Operates within acceptable parameter ranges for most applications.

Engineering Selection Recommendations

Primary Recommendation: FPG.00.303.CLAD35 (LEMO)

This part is the preferred substitute. It maintains identical electrical and mechanical specifications to the obsolete FHG.00.303.CLAD35, including shell size 303, 3-position configuration, solder cup termination, and full temperature range (-55°C to 250°C). Both parts are ROHS3 compliant and REACH unaffected. The FPG.00.303.CLAD35 carries active product status, ensuring long-term availability and manufacturer support. Inventory of 789 units is currently available.

Secondary Alternative: W1CL0C-P03MCC0-2500 (ODU MINI-SNAP® L)

This cross-manufacturer option is suitable for applications where the operating temperature range can be limited to -40°C to 120°C and electromagnetic shielding is not critical. The ODU connector provides equivalent 3-position male pin configuration, solder cup termination, and push-pull fastening with a higher current rating (4A). However, this part features an unshielded design and reduced temperature range compared to the original specification. Use this substitute only when application requirements permit these parameter deviations. Inventory of 832 units is available.

Frequently Asked Questions (FAQ)

Q: Can FPG.00.303.CLAD35 be used as a direct drop-in replacement for FHG.00.303.CLAD35?

A: Yes. Both parts share identical specifications for connector type, position count, shell size, termination method, fastening mechanism, contact finish, current rating, and operating temperature range. No design modifications are required.

Q: What are the key differences between the LEMO and ODU substitutes?

A: The primary differences are operating temperature range (ODU limited to -40°C to 120°C versus LEMO -55°C to 250°C), shielding (ODU is unshielded versus LEMO shielded), and shell material composition (ODU copper alloy versus LEMO brass). Current rating is higher on the ODU part (4A versus 3A).

Q: Is the ODU W1CL0C-P03MCC0-2500 suitable for high-temperature applications?

A: No. The ODU connector operates only to 120°C maximum, making it unsuitable for applications requiring the original -55°C to 250°C range. Use FPG.00.303.CLAD35 for extended temperature requirements.

Q: Does the unshielded design of the ODU connector affect signal integrity?

A: Unshielded connectors lack electromagnetic interference protection. Applications requiring EMI rejection or operating in electromagnetically noisy environments should use the shielded LEMO FPG.00.303.CLAD35 instead.

Q: What is the packaging format for these substitute parts?

A: FPG.00.303.CLAD35 is supplied in bulk packaging. W1CL0C-P03MCC0-2500 is also supplied in bulk packaging. Both are suitable for production assembly and repair operations.

Q: Are both substitute parts RoHS compliant?

A: FPG.00.303.CLAD35 is ROHS3 compliant. RoHS status for W1CL0C-P03MCC0-2500 is not specified in available documentation.
