Substitute Part Grouping Explanation

Substitution of the FGG.1K.314.CLAC55Z is based on the following critical parameters that must align for functional compatibility:

Core Compatibility Criteria:

• Connector type: Plug with male pins
• Position count: 14 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding: Shielded configuration
• Contact finish: Gold plating on mating surfaces
• Shell material: Brass construction
• Insert material: Polyetheretherketone (PEEK)

The identified substitute part S21K0C-P14MCC0-550S from ODU meets these core criteria. Both parts share identical functional architecture for 14-position shielded circular connectors with solder cup termination and push-pull fastening. Variations exist in operating temperature range, current rating, and shell finish specifications, which are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1K.314.CLAC55Z and S21K0C-P14MCC0-550S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The FGG.1K.314.CLAC55Z is suitable for applications requiring extended operating temperature range (-55°C to 200°C) and IP66/IP68 dual ingress protection rating. The 2A current rating is appropriate for signal-level and moderate power distribution circuits.

The S21K0C-P14MCC0-550S provides higher current capacity (4A) within a more limited operating temperature range (-40°C to 120°C) and IP68 waterproof rating. This substitute is applicable in industrial, medical, military, and testing equipment environments where the temperature and current specifications align with system requirements.

Selection between these parts depends on application-specific thermal and electrical load requirements. Both parts maintain identical mechanical interface geometry, pin count, and termination method, ensuring physical and electrical compatibility within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the S21K0C-P14MCC0-550S replace the FGG.1K.314.CLAC55Z in all applications?

A: Substitution is valid only when the application operating temperature remains within -40°C to 120°C and current requirements do not exceed 4A. Applications requiring temperatures below -40°C or above 120°C must use the FGG.1K.314.CLAC55Z.

Q: What are the mechanical compatibility considerations?

A: Both connectors share identical 14-position solder cup configuration, push-pull fastening, and shielded design. Cable opening tolerances are compatible within the 5.00mm to 5.50mm range. Physical mating and PCB footprint compatibility is maintained.

Q: Are there differences in shell finish that affect performance?

A: The FGG.1K.314.CLAC55Z uses chrome finish on brass, while the S21K0C-P14MCC0-550S uses chrome over nickel finish. Both finishes provide corrosion resistance. The nickel underplate in the substitute part may offer enhanced durability in certain corrosive environments.

Q: How do the current ratings differ in practical application?

A: The FGG.1K.314.CLAC55Z is rated for 2A per contact, suitable for signal circuits and low-power applications. The S21K0C-P14MCC0-550S supports 4A per contact, accommodating higher power distribution requirements within its temperature operating range.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for industrial and commercial use.

Q: What is the difference between IP66/IP68 and IP68 ratings?

A: The FGG.1K.314.CLAC55Z provides dual rating (IP66 dust tight and water resistant; IP68 waterproof). The S21K0C-P14MCC0-550S provides IP68 waterproof rating only. Both ratings ensure protection against dust and water ingress suitable for harsh environments.
