FHG.0B.307.CLAD52Z Equivalent & Substitute Parts

Part Overview

The FHG.0B.307.CLAD52Z is a 7-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector features a 307 shell size with push-pull fastening, gold-plated mating contacts, and shielded construction rated for 2.5A at operating temperatures from -55°C to 250°C. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.0B.307.CLAD52Z is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Plug with male pins
• Number of positions: 7
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Contact finish: Gold plating on mating surfaces
• Ingress protection: IP50 minimum
• RoHS3 compliance

Secondary Compatibility Considerations:

• Operating temperature range must encompass or match the application requirement
• Current rating must meet or exceed the circuit demand
• Shell size and insert dimensions must ensure mechanical fit
• Shielding configuration must match the application's EMI requirements

Two substitute parts are identified:

1. FPG.0B.307.CLAD52Z (LEMO) — Manufacturer-recommended equivalent with identical electrical and mechanical specifications. Active product status provides long-term availability.

2. W20L0C-P07MCC0-520S (ODU) — Cross-manufacturer substitute from the ODU MINI-SNAP® L series. Maintains core functional compatibility with differences in shell size designation, operating temperature range, and current rating.

Parameter Comparison

Engineering Selection Recommendations

FPG.0B.307.CLAD52Z (LEMO) — Preferred Substitute

This part is the direct equivalent to the obsolete FHG.0B.307.CLAD52Z. Electrical specifications, mechanical dimensions, and environmental ratings are identical. The primary distinction is active product status, ensuring availability and supply chain continuity. Both parts share the same base product number (0B series) and shell size (307), confirming design compatibility. ROHS3 compliance and identical operating temperature range (-55°C to 250°C) support direct substitution in legacy systems without circuit redesign.

W20L0C-P07MCC0-520S (ODU MINI-SNAP® L) — Cross-Manufacturer Alternative

This ODU connector provides functional substitution when FPG.0B.307.CLAD52Z availability is constrained. Core compatibility is maintained through identical connector type, pin count, termination method, and push-pull fastening. However, three parameter differences require evaluation:

• Operating Temperature: ODU part rated -40°C to 120°C versus LEMO's -55°C to 250°C. Suitable only for applications within the ODU temperature envelope.
• Current Rating: ODU part rated 4A versus LEMO's 2.5A. Provides higher current capacity.
• Shielding: ODU part is unshielded versus LEMO's shielded design. Acceptable only in applications without EMI sensitivity requirements.
• Shell Size: ODU designation "0" differs from LEMO "307," but cable opening ranges overlap (4.00mm ~ 5.20mm versus 4.20mm ~ 5.20mm), supporting mechanical compatibility.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for the original application.

Frequently Asked Questions (FAQ)

Q: Can FPG.0B.307.CLAD52Z directly replace FHG.0B.307.CLAD52Z without any modifications?

A: Yes. FPG.0B.307.CLAD52Z is the active equivalent with identical electrical, mechanical, and environmental specifications. No circuit or mechanical modifications are required. The primary difference is product status: FHG is obsolete while FPG is active.

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

A: FPG.0B.307.CLAD52Z (LEMO) is electrically and mechanically identical to the original. W20L0C-P07MCC0-520S (ODU) differs in three areas: operating temperature range (-40°C to 120°C versus -55°C to 250°C), current rating (4A versus 2.5A), and shielding (unshielded versus shielded). Shell size designations differ but cable opening ranges are compatible.

Q: Can W20L0C-P07MCC0-520S be used in applications requiring the full -55°C to 250°C temperature range?

A: No. The ODU part is rated only to -40°C minimum and 120°C maximum. Use is restricted to applications operating within this narrower temperature envelope. For full temperature range compatibility, use FPG.0B.307.CLAD52Z.

Q: Is the unshielded design of the ODU connector acceptable for my application?

A: Unshielded design is acceptable only in applications without electromagnetic interference (EMI) sensitivity. If the original application required shielding, the ODU substitute is not appropriate. Use FPG.0B.307.CLAD52Z to maintain shielded construction.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both FPG.0B.307.CLAD52Z and W20L0C-P07MCC0-520S are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for the original FHG.0B.307.CLAD52Z application.

Q: What is the cable opening tolerance, and does it affect connector selection?

A: FHG.0B.307.CLAD52Z and FPG.0B.307.CLAD52Z accept cable diameters 0.165" to 0.205" (4.20mm to 5.20mm). W20L0C-P07MCC0-520S accepts 0.157" to 0.205" (4.00mm to 5.20mm). Verify your cable diameter falls within the selected connector's range before final selection.

Q: Can I use W20L0C-P07MCC0-520S if my application requires higher current capacity?

A: The ODU part's 4A rating exceeds the original 2.5A requirement, providing additional current capacity. However, this advantage must be weighed against the narrower operating temperature range and unshielded design. Confirm all three parameter differences are acceptable for your specific application before substitution.
