Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.0B.305.CLAD52Z is determined by the following critical parameters:

• Connector Type & Pin Configuration: Must be plug with male pins, 5-position configuration
• Shell Size & Mechanical Compatibility: Shell size 305 ensures physical mating compatibility
• Termination Method: Solder cup termination for direct PCB or cable integration
• Fastening Mechanism: Push-pull fastening type for consistent connection/disconnection cycles
• Electrical Performance: Current rating of 6.5A minimum, gold-plated mating contacts for reliable signal transmission
• Environmental Compliance: ROHS3 compliance and operating temperature range support

Two substitute parts meet these criteria:

1. FPG.0B.305.CLAD52Z (LEMO, MFR Recommended) - Active product with identical core specifications and enhanced fastening features
2. W20L0C-P05MFG0-520S (ODU, Similar Alternative) - Active product with compatible electrical and mechanical parameters, alternative manufacturer design

Parameter Comparison

Engineering Selection Recommendations

FPG.0B.305.CLAD52Z is the manufacturer-recommended substitute. As an active LEMO product within the same 0B series, it maintains identical shell size (305), electrical ratings (6.5A), operating temperature range (-55°C ~ 250°C), and shielding characteristics. The primary difference is enhanced fastening with detent lock capability and solder termination (versus solder cup). ROHS3 compliance and identical insert material (PEEK) ensure direct compatibility in existing designs.

W20L0C-P05MFG0-520S is a functionally compatible alternative from ODU. It meets the core electrical requirements (5-position, male pins, push-pull fastening, gold contacts, PEEK insert) and provides higher current capacity (7.5A). However, this substitute has three material and environmental differences: unshielded design (versus shielded), reduced operating temperature range (-40°C ~ 120°C versus -55°C ~ 250°C), and different shell finish (chrome over nickel). Selection of this part requires confirmation that the application does not require shielding and operates within the -40°C ~ 120°C temperature window.

Frequently Asked Questions (FAQ)

Q: Can FPG.0B.305.CLAD52Z directly replace FHG.0B.305.CLAD52Z in existing assemblies?

A: FPG.0B.305.CLAD52Z is mechanically and electrically compatible. Both connectors share identical shell size (305), 5-position configuration, push-pull fastening, and operating specifications. The primary difference is termination method (solder versus solder cup) and enhanced detent lock on the substitute. Mechanical fit and electrical performance are equivalent.

Q: What are the key differences between the two substitute parts?

A: FPG.0B.305.CLAD52Z is a LEMO product maintaining the same series and specifications as the original. W20L0C-P05MFG0-520S is an ODU alternative with higher current rating (7.5A) but unshielded design and narrower operating temperature range (-40°C ~ 120°C). Selection depends on shielding requirements and temperature environment.

Q: Is the W20L0C-P05MFG0-520S suitable for high-temperature applications?

A: No. The W20L0C-P05MFG0-520S operates within -40°C ~ 120°C, which is significantly narrower than the original FHG.0B.305.CLAD52Z (-55°C ~ 250°C). Applications requiring extended temperature range must use FPG.0B.305.CLAD52Z.

Q: Does the unshielded design of W20L0C-P05MFG0-520S affect signal integrity?

A: The original FHG.0B.305.CLAD52Z is shielded; W20L0C-P05MFG0-520S is unshielded. Applications requiring electromagnetic interference protection must retain shielded connectors. Unshielded designs are suitable only for non-critical signal applications.

Q: Are all three connectors ROHS3 compliant?

A: Yes. FHG.0B.305.CLAD52Z, FPG.0B.305.CLAD52Z, and W20L0C-P05MFG0-520S are all ROHS3 compliant and REACH unaffected.

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

A: FHG.0B.305.CLAD52Z: 0.165" ~ 0.205" (4.20mm ~ 5.20mm); FPG.0B.305.CLAD52Z: 0.169" ~ 0.205" (4.30mm ~ 5.20mm); W20L0C-P05MFG0-520S: 0.157" ~ 0.205" (4.00mm ~ 5.20mm). All ranges overlap within 4.20mm ~ 5.20mm, supporting standard cable diameters.
