FGG.0B.303.CLAD25Z Equivalent & Substitute Parts

Part Overview

The FGG.0B.303.CLAD25Z is a 3-position circular connector plug manufactured by LEMO, featuring male pins with solder cup termination. 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 maintains active product status with 882 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative connector series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.0B.303.CLAD25Z is determined by strict alignment of the following critical parameters:

Core Electrical & Mechanical Criteria:

• Connector type: Plug with male pins
• Position count: 3 positions
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Shielding configuration: Shielded
• Contact finish: Gold plating on mating surfaces
• Ingress protection rating: IP50 or equivalent
• Insert material: PEEK

Environmental & Compliance Criteria:

• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status
• Material flammability rating: UL94 V-0 or equivalent

The substitute part S20L0C-P03MJG0-320S from ODU meets these core criteria, enabling functional equivalence in applications where the LEMO FGG.0B.303.CLAD25Z is specified. Differences in operating temperature range, current rating, and shell finish specifications must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.0B.303.CLAD25Z and S20L0C-P03MJG0-320S maintain active product status and ROHS3 compliance, qualifying them for applications requiring regulatory adherence. The primary differentiators are operating temperature range and current rating capacity. The LEMO part supports extended temperature operation from -55°C to 250°C with 8A current capacity, while the ODU substitute operates within -40°C to 120°C with 7.5A capacity. Selection between these parts depends on application thermal and electrical load requirements. Both connectors provide equivalent mechanical interface, shielding, and contact finish specifications. The ODU part includes integrated strain relief features not specified for the LEMO connector.

Frequently Asked Questions (FAQ)

Q: Can the S20L0C-P03MJG0-320S replace the FGG.0B.303.CLAD25Z in all applications?

A: Substitution is valid only when application operating temperature remains within -40°C to 120°C and current requirements do not exceed 7.5A. Applications requiring the full -55°C to 250°C temperature range or 8A current capacity require the original LEMO part.

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

A: The FGG.0B.303.CLAD25Z accepts cables of 0.091" to 0.126" (2.30mm to 3.20mm) diameter, while the S20L0C-P03MJG0-320S accepts 0.079" to 0.126" (2.00mm to 3.20mm). The ODU part accommodates a wider lower range, ensuring compatibility with smaller cable diameters.

Q: Do both connectors meet the same compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, enabling equivalent handling and storage protocols.

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

A: The LEMO FGG.0B.303.CLAD25Z features chrome plating directly on brass, while the ODU S20L0C-P03MJG0-320S uses chrome plating over a nickel intermediate layer. Both finishes provide corrosion resistance; the nickel underplate in the ODU part offers additional protection in harsh environments.

Q: Are solder cup terminations identical between these parts?

A: Both connectors use solder cup termination with identical functional interface. Solder joint procedures and thermal profiles remain consistent between parts.
