FGA.0B.309.CLAD56Z Equivalent & Substitute Parts

Part Overview

The FGA.0B.309.CLAD56Z is a 9-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector is part of the 0B series and features a push-pull fastening mechanism with shielded construction. The part is currently active in production with 1027 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part is unavailable or when design flexibility permits alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.0B.309.CLAD56Z is determined by the following critical parameters:

• Connector type and pin configuration (9-position plug with male pins)
• Termination method (solder cup)
• Fastening mechanism (push-pull)
• Shielding requirement (shielded)
• Contact material and finish (brass with gold mating surface)
• Insert material (PEEK)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The substitute part S20LAC-P09MCC0-560S from ODU meets these core electrical and mechanical requirements, enabling functional equivalence in applications where the original LEMO part is not available.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.309.CLAD56Z and S20LAC-P09MCC0-560S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The ODU substitute provides a higher current rating of 4A compared to the LEMO part's 2A rating. However, the LEMO connector supports an extended operating temperature range of -55°C to 250°C, whereas the ODU part operates between -40°C and 120°C. Selection between these parts must be based on the specific application's current and temperature requirements. Both connectors maintain equivalent mechanical compatibility through identical 9-position push-pull solder cup configuration with shielded brass construction and gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: Can the S20LAC-P09MCC0-560S replace the FGA.0B.309.CLAD56Z in all applications?

A: Substitution is valid when the application's operating temperature range falls within -40°C to 120°C and current requirements do not exceed 4A. Applications requiring operation below -40°C or above 120°C require the original LEMO part.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical 9-position configuration, push-pull fastening, solder cup termination, and shielded brass construction with gold-plated contacts. Physical mating and electrical interface compatibility is maintained.

Q: Are there differences in shell finish that affect performance?

A: The LEMO part features chrome finish, while the ODU substitute uses chrome over nickel. Both finishes provide equivalent corrosion protection and electrical performance for the specified ingress protection rating of IP50.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the FGA.0B.309.CLAD56Z and S20LAC-P09MCC0-560S are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the significance of the current rating difference?

A: The ODU substitute's 4A rating exceeds the LEMO part's 2A rating. This provides design margin in applications with moderate current requirements but does not indicate reduced performance at lower currents.
