Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1K.308.CLAC55Z is determined by the following critical parameters:

• Connector Configuration: 8-position circular connector plug with male pins
• Termination Method: Solder cup termination
• Fastening Mechanism: Push-pull coupling
• Electrical Performance: Shielded design with gold-plated mating contacts
• Environmental Rating: IP68 waterproof capability (minimum requirement)
• Regulatory Compliance: ROHS3 compliant status
• Material Compatibility: Brass shell with chrome finish; PEEK insert material

The substitute part S21K0C-P08MFG0-550S meets these core substitution criteria through equivalent connector topology, termination method, fastening type, and regulatory compliance. Variations in shell size designation, operating temperature range, and current rating represent design differences within the acceptable substitution envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1K.308.CLAC55Z and S21K0C-P08MFG0-550S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

The FGG.1K.308.CLAC55Z is suitable for applications requiring extended operating temperature range (-55°C to 200°C) and IP66 ingress protection capability. The S21K0C-P08MFG0-550S is suitable for applications within the -40°C to 120°C operating window with IP68 waterproof rating and higher current capacity (7.5A versus 5A). Cable opening dimensions are compatible between both parts within the specified tolerance ranges.

Selection between these parts depends on specific application requirements regarding temperature extremes and current load. Both parts maintain equivalent connector topology, termination method, and fastening mechanism.

Frequently Asked Questions (FAQ)

Q: Can the S21K0C-P08MFG0-550S replace the FGG.1K.308.CLAC55Z in all applications?

A: Substitution is valid when application operating temperature remains within -40°C to 120°C and current requirements do not exceed 7.5A. Applications requiring operation below -40°C or above 120°C require the FGG.1K.308.CLAC55Z.

Q: Are the cable opening dimensions compatible?

A: Yes. Both connectors accept cable diameters within the 5.00mm to 5.50mm range, with the FGG.1K.308.CLAC55Z specified at 5.10mm to 5.50mm and the S21K0C-P08MFG0-550S at 5.00mm to 5.50mm. Cable compatibility is maintained across the overlapping range.

Q: What is the difference in shell finish between these parts?

A: The FGG.1K.308.CLAC55Z features chrome finish on brass shell. The S21K0C-P08MFG0-550S features chrome over nickel finish on brass shell. Both finishes provide equivalent corrosion resistance and electrical performance for the specified applications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the current rating difference?

A: The FGG.1K.308.CLAC55Z is rated for 5A continuous current. The S21K0C-P08MFG0-550S is rated for 7.5A continuous current. Applications requiring current above 5A must use the S21K0C-P08MFG0-550S.
