Key Parameters

Substitute Part Grouping Explanation

Substitution of the FHG.00.303.CLAZ is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Plug, Male Pins)
• Number of positions (3)
• Shell size insert designation (303)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Orientation code (G)
• Shell and contact materials (Brass shell with chrome finish; gold-plated mating contacts)
• Shielding configuration (Shielded)
• Current rating (3A)
• Operating temperature range (-55°C ~ 250°C)
• Insert material (PEEK)
• Ingress protection class (IP50)
• Flammability compliance (UL94 V-0)

The FPG.00.303.CLAZ meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The FPG.00.303.CLAZ is the recommended substitute for the obsolete FHG.00.303.CLAZ. Both parts are manufactured by LEMO and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status, ensuring availability for procurement and future supply chain requirements.

The FPG.00.303.CLAZ carries the same compliance certifications as the original part, including ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status. The series designation differs (00 versus 00B), but this does not affect functional compatibility or performance characteristics. Both connectors are suitable for applications requiring 3-position, 3A-rated circular connectors with solder cup termination and push-pull fastening in the 303 shell size.

Frequently Asked Questions (FAQ)

Q: Are FHG.00.303.CLAZ and FPG.00.303.CLAZ mechanically compatible?

A: Yes. Both connectors share identical shell size (303), fastening type (push-pull), orientation (G), and physical dimensions. They are mechanically interchangeable.

Q: Do these parts have the same electrical ratings?

A: Yes. Both parts are rated for 3A current and operate across the same temperature range (-55°C to 250°C). Electrical performance is equivalent.

Q: What is the difference between the series designations (00B vs. 00)?

A: The series designation reflects manufacturing lineage. The FPG.00.303.CLAZ represents the current active series. The functional and electrical specifications remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the FHG.00.303.CLAZ and FPG.00.303.CLAZ are ROHS3 compliant and REACH unaffected.

Q: Can I use FPG.00.303.CLAZ as a direct replacement in existing designs?

A: Yes. The FPG.00.303.CLAZ is a direct functional equivalent and can be used as a replacement without design modifications.

Q: What is the contact finish thickness specification?

A: The contact finish thickness for the main part is specified as 39.4µin (1.00µm). This specification is not provided for the substitute part in the available data.
