FGG.0B.309.CYCD52Z Equivalent & Substitute Parts

Part Overview

The FGG.0B.309.CYCD52Z is a 9-position circular connector plug manufactured by LEMO, featuring male pins with crimp termination and push-pull fastening. This connector is actively produced and maintains 1146 units in current inventory. The connector is designed for free-hanging, in-line applications requiring shielded connections with IP50 dust protection and operates across an extended temperature range of -55°C to 250°C.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in applications where the primary part becomes unavailable or when alternative termination methods are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.0B.309.CYCD52Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug configuration with 9 positions
• Fastening Mechanism: Push-pull fastening required for mechanical compatibility
• Shielding: Shielded construction to maintain electromagnetic protection
• Contact Material & Finish: Gold-plated mating surface for electrical performance
• Ingress Protection: IP50 minimum rating for environmental sealing
• Compliance: ROHS3 compliance and REACH unaffected status

The identified substitute part S20L0C-P09MCC0-520S meets these core electrical and mechanical criteria. The primary difference is termination method (solder cup versus crimp), which represents a functional alternative rather than a compatibility limitation. The substitute operates at a higher current rating (4A versus 2A) and narrower temperature range (-40°C to 120°C versus -55°C to 250°C), making it suitable for applications within its specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.0B.309.CYCD52Z and S20L0C-P09MCC0-520S maintain active product status and full ROHS3 compliance with REACH unaffected designation, ensuring regulatory alignment for current applications.

Selection between these parts depends on application-specific requirements:

The FGG.0B.309.CYCD52Z is specified for applications requiring extended temperature operation (-55°C to 250°C) and crimp-based wire termination. This configuration is standard for aerospace, military, and high-temperature industrial environments.

The S20L0C-P09MCC0-520S provides solder cup termination with higher current capacity (4A) and is suitable for applications operating within -40°C to 120°C. This termination method is preferred in applications where solder-based assembly processes are established.

Both connectors share identical mechanical fastening (push-pull), shielding architecture, ingress protection rating, and contact finish specifications, confirming functional interchangeability within their respective operating temperature and termination method constraints.

Frequently Asked Questions (FAQ)

Q: Can the S20L0C-P09MCC0-520S directly replace the FGG.0B.309.CYCD52Z in all applications?

A: Direct replacement is possible only when the application operates within the S20L0C-P09MCC0-520S temperature range (-40°C to 120°C) and when solder cup termination is compatible with the assembly process. Applications requiring crimp termination or extended temperature operation (-55°C to 250°C) must use the FGG.0B.309.CYCD52Z.

Q: What is the significance of the different termination methods?

A: Crimp termination (FGG.0B.309.CYCD52Z) uses mechanical compression to secure wire connections and is preferred for high-reliability applications. Solder cup termination (S20L0C-P09MCC0-520S) uses solder to establish electrical connection and is common in applications with established solder assembly infrastructure.

Q: Are both connectors compatible with the same mating receptacles?

A: Both connectors are 9-position plugs with push-pull fastening and identical contact finish specifications. Mechanical compatibility with mating receptacles depends on the specific receptacle design and series designation.

Q: What are the packaging considerations?

A: Both parts are supplied in bulk packaging. The FGG.0B.309.CYCD52Z has 1146 units in current inventory, while the S20L0C-P09MCC0-520S has 932 units available.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.
