FGG.1B.303.CLAD72Z Equivalent & Substitute Parts

Part Overview

The FGG.1B.303.CLAD72Z is a 3-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 product is active and in stock with 721 units available. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits equivalent connector selection.

Key Parameters

Substitute Part Grouping Explanation

The substitute part S21L0C-P03MPH0-720S (ODU MINI-SNAP® L series) qualifies as an equivalent based on the following critical parameters:

• Connector type and gender: Plug with male pins
• Contact count: 3 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Contact finish: Gold-plated mating surfaces
• Current capacity: 12A
• Ingress protection: IP50 dust protection
• Shell material: Brass construction
• Insert material: PEEK
• Regulatory compliance: ROHS3 compliant, REACH unaffected, EAR99 classification

Substitution is valid where mechanical envelope, cable opening tolerance, and operating temperature range compatibility are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

Both connectors meet ROHS3 compliance and REACH requirements, with EAR99 export classification. The FGG.1B.303.CLAD72Z operates across -55°C to 250°C, while the S21L0C-P03MPH0-720S operates within -40°C to 120°C. Selection between these parts depends on application temperature requirements. Where operating temperatures remain within -40°C to 120°C, the ODU substitute provides equivalent electrical and mechanical performance. For applications requiring extended temperature operation below -40°C or above 120°C, the LEMO part is required. Both parts are active products with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the ODU S21L0C-P03MPH0-720S replace the LEMO FGG.1B.303.CLAD72Z in all applications?

A: Substitution is valid for applications where the operating temperature range of -40°C to 120°C is acceptable. If your application requires operation below -40°C or above 120°C, the LEMO part is necessary.

Q: Are the cable opening tolerances compatible between these connectors?

A: Yes. The LEMO part accepts cables 6.20mm to 7.20mm, while the ODU part accepts 6.00mm to 7.20mm. The ODU tolerance is slightly wider at the lower end, making it compatible with LEMO cable specifications.

Q: Do both connectors have identical shell finishes?

A: The LEMO part features chrome plating on brass, while the ODU part features chrome over nickel plating on brass. Both provide corrosion protection and are mechanically compatible.

Q: Are regulatory certifications equivalent?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: What is the current rating for both connectors?

A: Both the LEMO FGG.1B.303.CLAD72Z and ODU S21L0C-P03MPH0-720S are rated for 12A continuous current.

Q: Are the solder cup terminations compatible with the same PCB footprints?

A: Both connectors use solder cup termination with identical contact materials (brass) and gold plating. Mechanical envelope differences should be verified against your specific PCB layout before substitution.
