FHG.00.304.CLAD27Z Equivalent & Substitute Parts

Part Overview

The FHG.00.304.CLAD27Z is a 4-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector features a 304 shell size with push-pull fastening, gold-plated mating contacts, and shielded construction rated for 2A current at operating temperatures from -55°C to 250°C. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.00.304.CLAD27Z is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Plug with male pins
• Number of positions: 4
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shell size compatibility: 304 or equivalent
• Contact finish: Gold-plated mating surface
• Ingress protection: IP50 minimum

Substitute Categories:

MFR Recommended Equivalent: FPG.00.304.CLAD27Z (LEMO) — Direct series upgrade from 00B to 00 series with identical mechanical and electrical specifications, active product status, and full parameter compatibility.

Similar Substitute: W2CL0C-P04MCC0-2500 (ODU) — Cross-manufacturer alternative from ODU MINI-SNAP® L series meeting core functional requirements (4-position, male pins, solder cup, push-pull, shielded construction) with differences in shell material, current rating, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): FPG.00.304.CLAD27Z is the manufacturer-recommended equivalent. This LEMO part maintains identical mechanical dimensions (304 shell size), electrical ratings (2A, -55°C to 250°C), and functional characteristics as the obsolete FHG.00.304.CLAD27Z. The transition from 00B to 00 series represents a product line consolidation with full backward compatibility. Active product status ensures long-term availability and supply chain stability. RoHS3 compliance and UL94 V-0 flammability rating are maintained.

For Cross-Manufacturer Substitution: W2CL0C-P04MCC0-2500 (ODU MINI-SNAP® L series) provides functional equivalence with the following considerations: The connector maintains 4-position, male pin, solder cup, and push-pull architecture with IP50 ingress protection. However, this substitute differs in three critical parameters: (1) unshielded construction versus shielded, (2) reduced operating temperature range (-40°C to 120°C versus -55°C to 250°C), and (3) different shell size designation (0 versus 304). The higher current rating (4A) and active product status are advantages. Selection of this substitute requires confirmation that the application does not require shielding and operates within the narrower temperature range.

Frequently Asked Questions (FAQ)

Q: Can FPG.00.304.CLAD27Z directly replace FHG.00.304.CLAD27Z without modification?

A: Yes. FPG.00.304.CLAD27Z is the manufacturer-recommended equivalent with identical connector type, position count, shell size, termination method, fastening mechanism, and electrical ratings. The series designation change (00B to 00) reflects product line consolidation, not functional change.

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

A: FPG.00.304.CLAD27Z (LEMO) is a direct equivalent. W2CL0C-P04MCC0-2500 (ODU) is a cross-manufacturer alternative with three material differences: unshielded versus shielded construction, operating temperature range of -40°C to 120°C versus -55°C to 250°C, and different shell size designation. Both maintain 4-position, male pin, solder cup, push-pull, and gold-plated contact specifications.

Q: Is the ODU W2CL0C-P04MCC0-2500 suitable for applications requiring shielding?

A: No. The W2CL0C-P04MCC0-2500 is unshielded, whereas the original FHG.00.304.CLAD27Z and recommended FPG.00.304.CLAD27Z are shielded. Applications requiring electromagnetic interference protection must use a shielded connector.

Q: What is the impact of the different operating temperature ranges?

A: The original FHG.00.304.CLAD27Z and recommended FPG.00.304.CLAD27Z operate from -55°C to 250°C. The ODU W2CL0C-P04MCC0-2500 operates from -40°C to 120°C. Applications requiring operation below -40°C or above 120°C must use the LEMO connectors.

Q: Are all three connectors RoHS compliant?

A: The FHG.00.304.CLAD27Z is ROHS3 compliant. RoHS compliance status for FPG.00.304.CLAD27Z and W2CL0C-P04MCC0-2500 is not specified in the provided data.

Q: What is the cable opening tolerance difference between substitutes?

A: FHG.00.304.CLAD27Z: 0.087" ~ 0.106" (2.20mm ~ 2.70mm); FPG.00.304.CLAD27Z: 0.091" ~ 0.106" (2.30mm ~ 2.70mm); W2CL0C-P04MCC0-2500: 0.079" ~ 0.098" (2.00mm ~ 2.50mm). Cable diameter specifications must be verified against application requirements.
