Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FHG.0B.304.CLAD52Z are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Connector type (Plug, Male Pins)
• Number of positions (4)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Mounting configuration (Free Hanging, Right Angle)
• Current rating (7A or higher)
• Operating temperature range capability
• Cable opening dimensions
• Contact finish (Gold plating)
• Ingress protection level (IP50 minimum)

Substitute Categories:

Category 1: Direct Manufacturer Equivalent FPG.0B.304.CLAD52Z is the direct equivalent from LEMO, sharing identical specifications with the obsolete FHG.0B.304.CLAD52Z. This part maintains the same series designation (0B), shell size (304), and all electrical and mechanical parameters. The primary distinction is product status: FPG.0B.304.CLAD52Z is active and available, whereas FHG.0B.304.CLAD52Z is obsolete.

Category 2: Cross-Manufacturer Substitute W20L0C-P04MFG0-520S from ODU is a functionally compatible substitute that meets the core requirements for 4-position, male-pin, solder-cup circular connectors with push-pull fastening. This part operates within acceptable parameter ranges for the application, though certain specifications differ from the original design.

Engineering Selection Recommendations

FPG.0B.304.CLAD52Z (LEMO) - Primary Recommendation

FPG.0B.304.CLAD52Z is the recommended substitute for the obsolete FHG.0B.304.CLAD52Z. This part is manufactured by LEMO and maintains identical electrical and mechanical specifications, including the full operating temperature range of -55°C to 250°C, shielded design, and ROHS3 compliance. The part is currently active and available in inventory. Selection of this equivalent ensures direct compatibility with existing designs and eliminates the need for circuit or mechanical redesign.

W20L0C-P04MFG0-520S (ODU) - Alternative Substitute

W20L0C-P04MFG0-520S from ODU serves as a functional alternative when FPG.0B.304.CLAD52Z is unavailable. This connector meets the core functional requirements: 4-position male-pin solder-cup design with push-pull fastening and IP50 ingress protection. The part provides slightly higher current capacity (7.5A versus 7A) and maintains gold-plated contacts. However, the operating temperature range is limited to -40°C to 120°C, which is narrower than the original specification. Additionally, this connector is unshielded, whereas the original design is shielded. These differences must be evaluated against specific application requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can FPG.0B.304.CLAD52Z be used as a direct replacement for FHG.0B.304.CLAD52Z?

A: Yes. FPG.0B.304.CLAD52Z is the direct equivalent manufactured by LEMO. All electrical, mechanical, and environmental specifications are identical. The only difference is product status: FHG.0B.304.CLAD52Z is obsolete while FPG.0B.304.CLAD52Z is active and available.

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

A: FPG.0B.304.CLAD52Z (LEMO) maintains identical specifications to the original part. W20L0C-P04MFG0-520S (ODU) differs in three areas: operating temperature range (-40°C to 120°C versus -55°C to 250°C), shielding (unshielded versus shielded), and current rating (7.5A versus 7A). Both maintain 4-position, male-pin, solder-cup configuration with push-pull fastening.

Q: Is the ODU connector suitable for high-temperature applications?

A: No. The W20L0C-P04MFG0-520S operates only to 120°C maximum, making it unsuitable for applications requiring the original -55°C to 250°C range. Applications requiring extended temperature operation must use FPG.0B.304.CLAD52Z.

Q: Does the unshielded design of the ODU connector affect compatibility?

A: The unshielded design of W20L0C-P04MFG0-520S differs from the shielded original. Applications requiring electromagnetic shielding must use FPG.0B.304.CLAD52Z. Applications without shielding requirements may use the ODU connector.

Q: Are both substitute parts RoHS compliant?

A: FPG.0B.304.CLAD52Z is ROHS3 compliant. RoHS compliance status for W20L0C-P04MFG0-520S is not specified in available documentation.

Q: What is the cable opening tolerance for each connector?

A: FHG.0B.304.CLAD52Z and FPG.0B.304.CLAD52Z both accept cables 0.165" to 0.205" (4.20mm to 5.20mm). W20L0C-P04MFG0-520S accepts cables 0.157" to 0.205" (4.00mm to 5.20mm), providing slightly greater lower tolerance.
