Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1K.314.CLAC45Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug configuration with 14 male pin positions
• Termination Method: Solder cup termination required
• Fastening Mechanism: Push-pull fastening type
• Shielding: Shielded configuration
• Contact Finish: Gold-plated mating surfaces
• Shell Material & Finish: Brass construction with protective finish
• Ingress Protection: IP66/IP68 rating or equivalent
• Mounting Style: Free hanging (in-line) configuration

The substitute part S21K0C-P14MCC0-450S meets these core substitution criteria. Both parts share identical connector type, position count, termination method, fastening type, shielding, contact finish, shell material, and mounting configuration. Variations exist in shell size designation, operating temperature range, current rating, and backshell material specifications, which are documented in the parameter comparison table below.

Engineering Selection Recommendations

Both the FGG.1K.314.CLAC45Z and S21K0C-P14MCC0-450S are active products with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts should be based on application-specific requirements:

The FGG.1K.314.CLAC45Z supports extended operating temperature range (-55°C to 200°C) and is appropriate for high-temperature applications. The S21K0C-P14MCC0-450S operates within -40°C to 120°C and provides higher current capacity (4A versus 2A). Both connectors maintain IP68 waterproof rating and identical core electrical and mechanical specifications for the 14-position solder cup configuration.

Frequently Asked Questions (FAQ)

Q: Can S21K0C-P14MCC0-450S replace FGG.1K.314.CLAC45Z in all applications?

A: Substitution is valid when application requirements fall within the S21K0C-P14MCC0-450S operating parameters. The substitute part supports lower operating temperatures (-40°C minimum versus -55°C) and lower maximum temperature (120°C versus 200°C). Verify that your application temperature range does not exceed -40°C to 120°C before substitution.

Q: What are the key compatibility factors for these connectors?

A: Both connectors share identical 14-position configuration, solder cup termination, push-pull fastening, shielded design, and gold-plated contacts. Cable opening dimensions are compatible (0.157" to 0.177" overlap). Both use PEEK inserts and brass shells with protective finishes.

Q: Are there differences in current handling capacity?

A: Yes. The FGG.1K.314.CLAC45Z is rated for 2A, while the S21K0C-P14MCC0-450S supports 4A. If your application requires current capacity above 2A, the substitute part provides additional margin. If your design is optimized for 2A operation, both parts are functionally equivalent.

Q: What packaging considerations apply to these parts?

A: The FGG.1K.314.CLAC45Z is supplied in standard packaging with 840 units in stock. The S21K0C-P14MCC0-450S is supplied in bulk packaging with 901 units available. Verify packaging requirements with your procurement process before ordering.

Q: Are both connectors suitable for industrial and medical applications?

A: Both parts are ROHS3 compliant and REACH unaffected. The S21K0C-P14MCC0-450S is explicitly rated for industrial, medical, military, and testing equipment applications. The FGG.1K.314.CLAC45Z is an active LEMO product suitable for professional applications requiring extended temperature performance.
