Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1K.310.CLAC45Z is determined by the following critical parameters:

• Connector type and gender (Plug, Male Pins)
• Number of positions (10)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Contact finish (Gold)
• Shielding configuration (Shielded)
• Insert material (PEEK)
• RoHS compliance status (ROHS3 Compliant)

The substitute part S21K0C-P10MCC0-450S meets these core criteria, enabling functional equivalence in applications where the connector serves the same electrical and mechanical role. Variations in shell size, operating temperature range, current rating, and ingress protection level are noted in the parameter comparison and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1K.310.CLAC45Z and S21K0C-P10MCC0-450S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The FGG.1K.310.CLAC45Z offers an extended operating temperature range (-55°C to 200°C) and UL94 V-0 flammability rating, making it suitable for high-temperature and safety-critical environments. The S21K0C-P10MCC0-450S provides a higher current rating (4A versus 2.5A) and includes integrated strain relief features, offering advantages in applications with elevated power requirements or demanding mechanical environments.

Selection between these parts should be based on specific application requirements regarding temperature extremes, current capacity, and mechanical robustness. Both parts maintain equivalent electrical connectivity through 10-position solder cup termination with gold-plated contacts and push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can the S21K0C-P10MCC0-450S directly replace the FGG.1K.310.CLAC45Z in all applications?

A: Direct substitution is possible when application requirements fall within the operating parameters of the S21K0C-P10MCC0-450S. The substitute part supports the same 10-position solder cup configuration and push-pull fastening. However, applications requiring temperatures below -40°C or above 120°C, or those requiring UL94 V-0 certification, must use the original FGG.1K.310.CLAC45Z.

Q: What are the cable opening tolerance differences?

A: The FGG.1K.310.CLAC45Z accepts cable diameters of 0.161" to 0.177" (4.10mm to 4.50mm), while the S21K0C-P10MCC0-450S accepts 0.157" to 0.177" (4.00mm to 4.50mm). The substitute part accommodates slightly smaller minimum cable diameter. Verify cable dimensions against both specifications before substitution.

Q: How do the current ratings affect substitution decisions?

A: The FGG.1K.310.CLAC45Z is rated for 2.5A, while the S21K0C-P10MCC0-450S is rated for 4A. The substitute part can handle higher current loads. If the application requires exactly 2.5A or less, either part is suitable. Applications exceeding 2.5A but within 4A capacity benefit from the higher-rated substitute.

Q: Are both parts suitable for IP68 applications?

A: The FGG.1K.310.CLAC45Z meets IP66/IP68 specifications. The S21K0C-P10MCC0-450S meets IP68 specifications. Both parts provide waterproof, dust-tight protection suitable for submerged or harsh environmental conditions.

Q: What is the significance of the shell finish difference?

A: The FGG.1K.310.CLAC45Z features chrome plating on brass, while the S21K0C-P10MCC0-450S features chrome over nickel plating on brass. The nickel underplate in the substitute part provides enhanced corrosion resistance in certain chemical environments. Both finishes are suitable for standard industrial applications.
