FGA.1B.307.CLAD52Z Equivalent & Substitute Parts

Part Overview

The FGA.1B.307.CLAD52Z is a 7-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 an extended temperature range of -55°C to 250°C. The part is currently active in production with 677 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component sourcing, inventory management, or design flexibility while maintaining connector compatibility.

Key Parameters

Substitute Part Grouping Explanation

The substitute part S21LAC-P07MFG0-520S (ODU MINI-SNAP® L series) qualifies as an equivalent based on the following critical parameters:

• 7-position connector configuration
• Male pin plug connector type
• Solder cup termination method
• Push-pull fastening mechanism
• Shielded design with gold-plated mating contacts
• IP50 ingress protection rating
• ROHS3 compliance and REACH unaffected status
• Brass shell material with chrome finish
• PEEK insert material
• Polyetheretherketone (PEEK) insert construction

Substitution is valid when these core electrical and mechanical parameters align between the main part and substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.307.CLAD52Z and S21LAC-P07MFG0-520S are active production parts with ROHS3 compliance and REACH unaffected status. The primary distinction lies in operating temperature range: the LEMO part supports -55°C to 250°C, while the ODU part operates within -40°C to 120°C. Selection between these parts depends on the specific thermal requirements of the application. The ODU substitute provides a higher current rating of 7.5A compared to 7A for the LEMO part. Both connectors maintain equivalent mechanical and electrical compatibility for 7-position solder cup applications with push-pull fastening and gold-plated contacts.

Frequently Asked Questions (FAQ)

Q: What determines if S21LAC-P07MFG0-520S can substitute for FGA.1B.307.CLAD52Z?

A: Substitution is valid when the connector maintains 7-position configuration, male pin plug type, solder cup termination, push-pull fastening, shielded design, gold-plated mating contacts, and IP50 ingress protection. Both parts meet these criteria.

Q: Are there temperature limitations when using the ODU substitute?

A: The ODU MINI-SNAP® L series operates within -40°C to 120°C, which is narrower than the LEMO part's -55°C to 250°C range. Applications requiring operation outside the ODU temperature range must use the LEMO connector.

Q: Do both connectors have identical cable opening specifications?

A: The cable opening ranges differ slightly. LEMO specifies 0.165" ~ 0.205" (4.20mm ~ 5.20mm), while ODU specifies 0.157" ~ 0.205" (4.00mm ~ 5.20mm). Both ranges overlap sufficiently for standard cable gauges within the 4.20mm ~ 5.20mm window.

Q: What is the difference in shell finish between these connectors?

A: The LEMO part features chrome finish on brass, while the ODU part features chrome over nickel on brass. Both provide equivalent corrosion protection and electrical performance for shielded applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both FGA.1B.307.CLAD52Z and S21LAC-P07MFG0-520S are ROHS3 compliant and REACH unaffected.
