FGG.1B.314.CYCD52Z Equivalent & Substitute Parts

Part Overview

The FGG.1B.314.CYCD52Z is a 14-position circular connector plug manufactured by LEMO, featuring male pins with crimp termination. This connector is designed for free-hanging, in-line applications requiring shielded connections with push-pull fastening. The part is currently active in production with 1,087 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part is unavailable, discontinued, or when alternative termination methods are preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1B.314.CYCD52Z is determined by the following critical parameters:

• Connector Type & Gender: Must be plug with male pins
• Position Count: Must be 14 positions
• Fastening Mechanism: Must be push-pull compatible
• Shielding: Must be shielded
• Contact Material & Finish: Must be brass with gold mating finish
• Ingress Protection: Must maintain IP50 or equivalent dust protection
• Compliance: Must be ROHS3 compliant and REACH unaffected

The substitute part S21L0C-P14MCC0-520S meets these core electrical and mechanical criteria. However, differences exist in termination method (solder cup vs. crimp), current rating (4A vs. 2A), and operating temperature range (-40°C ~ 120°C vs. -55°C ~ 250°C), which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.314.CYCD52Z and S21L0C-P14MCC0-520S are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts depends on application-specific requirements:

The FGG.1B.314.CYCD52Z is specified when crimp termination is required and operating temperatures exceed 120°C or fall below -40°C. The extended temperature range of -55°C ~ 250°C supports high-temperature industrial and aerospace applications.

The S21L0C-P14MCC0-520S is applicable when solder cup termination is preferred and operating conditions remain within -40°C ~ 120°C. The higher current rating of 4A accommodates applications requiring greater current capacity than the 2A rating of the LEMO connector.

Both connectors maintain identical 14-position configuration, push-pull fastening, shielding, and IP50 ingress protection, ensuring mechanical and environmental compatibility within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the S21L0C-P14MCC0-520S directly replace the FGG.1B.314.CYCD52Z?

A: Direct mechanical replacement is possible due to identical position count, push-pull fastening, and shielding. However, termination method differs (solder cup vs. crimp), requiring cable assembly modification. Operating temperature range and current rating differences must be verified against application requirements.

Q: What is the primary difference between these two connectors?

A: The main differences are termination method (crimp vs. solder cup), operating temperature range (-55°C ~ 250°C vs. -40°C ~ 120°C), and current rating (2A vs. 4A). Both maintain identical electrical contact configuration and mechanical fastening.

Q: Are both connectors compliant with regulatory requirements?

A: Yes. Both the FGG.1B.314.CYCD52Z and S21L0C-P14MCC0-520S are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What cable opening specifications apply to each connector?

A: The FGG.1B.314.CYCD52Z accepts cable diameters of 0.165" ~ 0.205" (4.20mm ~ 5.20mm). The S21L0C-P14MCC0-520S accepts 0.157" ~ 0.205" (4.00mm ~ 5.20mm). Cable diameter must fall within the specified range for proper connector seating.

Q: Which connector is suitable for high-temperature applications?

A: The FGG.1B.314.CYCD52Z supports operating temperatures from -55°C to 250°C, making it suitable for high-temperature environments. The S21L0C-P14MCC0-520S is rated for -40°C ~ 120°C and is not recommended for applications exceeding 120°C.
