FHG.00.303.CLAD27 Equivalent & Substitute Parts

Part Overview

The FHG.00.303.CLAD27 is a 3-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector features a 303 shell size with push-pull fastening, gold-plated mating contacts, and shielded construction rated for 3A current and operating temperatures from -55°C to 250°C. The part is currently obsolete, making identification of equivalent and substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.00.303.CLAD27 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Plug with male pins
• Number of positions: 3
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Mounting configuration: Free hanging (in-line), right angle
• Contact finish: Gold plating on mating surfaces
• Ingress protection: IP50 minimum

Secondary Compatibility Criteria:

• Current rating: 3A minimum
• Operating temperature range: Must encompass or exceed -55°C to 250°C
• Shell material and finish: Brass with chrome plating preferred
• Shielding: Shielded construction
• Insert material: Polyetheretherketone (PEEK)

The FHG.00.303.CLAD27 has two identified substitutes: the LEMO FPG.00.303.CLAD27 (manufacturer-recommended equivalent) and the ODU W1CL0C-P03MCC0-2500 (similar alternative). Both maintain the core functional parameters required for direct substitution, though with specific trade-offs in operating temperature range and shielding characteristics.

Parameter Comparison

Engineering Selection Recommendations

FPG.00.303.CLAD27 (LEMO) - Manufacturer-Recommended Equivalent

The FPG.00.303.CLAD27 is the primary substitute for the obsolete FHG.00.303.CLAD27. Both parts share identical electrical and mechanical specifications, including shell size 303, 3-position configuration, 3A current rating, and -55°C to 250°C operating temperature range. The FPG.00.303.CLAD27 maintains active product status with ROHS3 compliance and EAR99 export classification. This part is the direct functional replacement with no parameter deviations.

W1CL0C-P03MCC0-2500 (ODU) - Alternative Substitute

The ODU W1CL0C-P03MCC0-2500 provides an alternative circular connector plug with 3 positions, solder cup termination, and push-pull fastening. This part offers a higher current rating of 4A and maintains gold-plated mating contacts with IP50 ingress protection. However, the operating temperature range is limited to -40°C to 120°C, which does not encompass the full -55°C to 250°C range of the original part. Additionally, the W1CL0C-P03MCC0-2500 features unshielded construction compared to the shielded design of the FHG.00.303.CLAD27. The cable opening specification is also narrower at 0.079" to 0.098" (2.00mm to 2.50mm). Selection of this part requires confirmation that the reduced temperature range and unshielded configuration are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the FPG.00.303.CLAD27 be used as a direct replacement for the FHG.00.303.CLAD27?

A: Yes. The FPG.00.303.CLAD27 is the manufacturer-recommended equivalent with identical specifications for connector type, number of positions, shell size, termination method, fastening type, current rating, operating temperature range, contact finish, and shielding. No design modifications are required.

Q: What are the limitations of the ODU W1CL0C-P03MCC0-2500 as a substitute?

A: The W1CL0C-P03MCC0-2500 has three key differences: (1) operating temperature range is limited to -40°C to 120°C, which does not cover the full -55°C to 250°C specification of the original part; (2) the connector is unshielded rather than shielded; (3) cable opening tolerance is narrower at 0.079" to 0.098" compared to 0.087" to 0.106". These differences must be evaluated against application requirements before selection.

Q: Are there compliance or certification differences between the substitutes?

A: The FPG.00.303.CLAD27 maintains ROHS3 compliance and EAR99 export classification identical to the original part. The W1CL0C-P03MCC0-2500 also carries EAR99 classification and the same HTSUS code. Both parts are suitable for industrial, medical, military, and testing equipment applications.

Q: What is the significance of shell size differences between the LEMO and ODU parts?

A: The FHG.00.303.CLAD27 and FPG.00.303.CLAD27 both use shell size 303, while the W1CL0C-P03MCC0-2500 uses shell size 0. Shell size determines the physical dimensions and mating interface. The different shell sizes indicate these are not mechanically interchangeable without adapter considerations.

Q: Can cable gauge requirements be accommodated by the different cable opening specifications?

A: The FHG.00.303.CLAD27 and FPG.00.303.CLAD27 accept cable diameters of 0.087" to 0.106" (2.20mm to 2.70mm). The W1CL0C-P03MCC0-2500 accepts narrower cables of 0.079" to 0.098" (2.00mm to 2.50mm). If the original application uses cables within the 0.087" to 0.098" range, the ODU part may accommodate them. Cables larger than 0.098" cannot be used with the ODU connector.
