FGA.0B.309.CLAD52Z Equivalent & Substitute Parts

Part Overview

The FGA.0B.309.CLAD52Z is a 9-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector is designed for applications requiring shielded, push-pull fastening with gold-plated mating contacts and operates across a wide temperature range of -55°C to 250°C. The part is currently active in production with 776 units in stock. Alternative models may be required due to inventory constraints, application-specific requirements, or design revisions necessitating compatible substitutes that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The substitute part S20LAC-P09MCC0-520S (ODU MINI-SNAP® L series) qualifies as an equivalent based on the following critical parameters:

• Connector Type & Configuration: Both are 9-position male plug connectors with solder cup termination
• Fastening Mechanism: Both utilize push-pull fastening
• Electrical Properties: Both feature gold-plated mating contacts and shielded construction
• Material Compatibility: Both use brass shells with chrome plating and PEEK inserts
• Ingress Protection: Both meet IP50 dust protection rating
• Compliance: Both are ROHS3 compliant and REACH unaffected

The substitution is valid for applications where the specified parameters align with system requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.309.CLAD52Z and S20LAC-P09MCC0-520S are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts should be based on application-specific operating temperature requirements and current capacity needs. The LEMO part supports extended temperature operation from -55°C to 250°C, while the ODU substitute operates within -40°C to 120°C. The ODU part provides higher current capacity at 4A versus 2A for the LEMO connector. Both parts maintain equivalent mechanical and electrical interfaces for 9-position solder cup termination with push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can S20LAC-P09MCC0-520S be used as a direct replacement for FGA.0B.309.CLAD52Z?

A: Yes, for applications operating within -40°C to 120°C and requiring up to 4A current capacity. The connectors share identical pin counts, termination methods, fastening mechanisms, and contact finishes. Physical compatibility exists for standard PCB and cable integration.

Q: What are the key differences between these two connectors?

A: The primary differences are operating temperature range (LEMO: -55°C to 250°C versus ODU: -40°C to 120°C), current rating (LEMO: 2A versus ODU: 4A), and shell finish plating (LEMO: Chrome versus ODU: Chrome over Nickel). Both maintain equivalent mechanical and electrical performance within their specified operating parameters.

Q: Are both connectors compliant with industry standards?

A: Both parts are ROHS3 compliant and REACH unaffected. Both are active production parts with established supply chains.

Q: What should be considered when selecting between these parts?

A: Evaluate your application's operating temperature requirements and current demands. If operation below -40°C or above 120°C is required, the LEMO FGA.0B.309.CLAD52Z is necessary. If higher current capacity is needed within the standard temperature range, the ODU S20LAC-P09MCC0-520S provides 4A capability.

Q: Are cable opening dimensions compatible?

A: Cable opening ranges are nearly identical with minimal variation. LEMO specifies 0.165" to 0.205" (4.20mm to 5.20mm), while ODU specifies 0.157" to 0.205" (4.00mm to 5.20mm). Both accommodate standard cable gauges within these ranges.
