Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.0B.305.CLAD42Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug with male pins, 5-position configuration
• Termination Method: Solder cup termination required
• Fastening Mechanism: Push-pull fastening type
• Mounting Configuration: Free hanging (in-line), right angle orientation
• Electrical Rating: Current capacity of 6.5A minimum
• Environmental Protection: IP50 ingress protection minimum
• Shielding: Shielded configuration
• Insert Material: Polyetheretherketone (PEEK)
• Operating Temperature Range: Must accommodate -55°C to 250°C or equivalent operational envelope

Two substitute parts meet these criteria:

1. FPG.0B.305.CLAD42Z (LEMO) - Manufacturer-recommended equivalent with identical mechanical and electrical specifications, active product status
2. W20L0C-P05MFG0-420S (ODU MINI-SNAP® L) - Similar connector meeting core functional requirements with noted parameter variations

Parameter Comparison

Engineering Selection Recommendations

FPG.0B.305.CLAD42Z is the primary substitute for FHG.0B.305.CLAD42Z. Both parts are manufactured by LEMO within the same 0B series and share identical mechanical dimensions, electrical ratings, and operating temperature specifications. The FPG variant maintains active product status, ensuring long-term availability and supply chain continuity. This part is recommended for direct replacement in applications requiring no design modification.

W20L0C-P05MFG0-420S (ODU MINI-SNAP® L) functions as an alternative substitute with the following considerations: The ODU connector provides higher current capacity (7.5A versus 6.5A) and maintains compatible cable opening specifications. However, the operating temperature range is restricted to -40°C to 120°C, which does not accommodate the full -55°C to 250°C envelope of the original part. Additionally, this connector is unshielded, whereas the FHG.0B.305.CLAD42Z is shielded. Selection of the ODU part requires confirmation that the reduced temperature range and absence of shielding are acceptable for the intended application.

Both substitute parts maintain PEEK insert material, push-pull fastening, and IP50 ingress protection, ensuring mechanical and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can FPG.0B.305.CLAD42Z be used as a direct replacement for FHG.0B.305.CLAD42Z?

A: Yes. Both connectors are LEMO 0B series 5-position circular plugs with identical shell size (305), solder cup termination, push-pull fastening, and electrical ratings (6.5A). Operating temperature range (-55°C to 250°C), shielding configuration, and PEEK insert material are identical. The FPG variant is the active production equivalent.

Q: What are the limitations of using W20L0C-P05MFG0-420S as a substitute?

A: The ODU MINI-SNAP® L connector has two parameter differences: operating temperature is limited to -40°C to 120°C (versus -55°C to 250°C for the original), and the connector is unshielded rather than shielded. Applications requiring the full temperature range or electromagnetic shielding cannot use this substitute without design review.

Q: Are cable opening specifications compatible across all three connectors?

A: The FHG.0B.305.CLAD42Z and FPG.0B.305.CLAD42Z share identical cable opening specifications (0.126" to 0.165" / 3.20mm to 4.20mm). The W20L0C-P05MFG0-420S has a slightly wider range (0.118" to 0.165" / 3.00mm to 4.20mm), providing greater flexibility for cable diameter accommodation.

Q: What compliance certifications apply to these connectors?

A: The FHG.0B.305.CLAD42Z is ROHS3 compliant and REACH unaffected. Compliance information for the FPG.0B.305.CLAD42Z and W20L0C-P05MFG0-420S is not specified in the provided data. All three connectors carry EAR99 ECCN classification and 8536.69.4020 HTSUS code.

Q: Can these connectors be used interchangeably in shielded applications?

A: The FHG.0B.305.CLAD42Z and FPG.0B.305.CLAD42Z are both shielded and suitable for electromagnetic interference-sensitive applications. The W20L0C-P05MFG0-420S is unshielded and is not appropriate for applications requiring shielding.
