FGG.0B.309.CLAD31Z Equivalent & Substitute Parts

Part Overview

The FGG.0B.309.CLAD31Z is a 9-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 product is active and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary connector becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.0B.309.CLAD31Z is determined by strict alignment of the following parameters:

• Connector type (Plug, Male Pins)
• Number of positions (9)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Shielding configuration (Shielded)
• Contact finish (Gold)
• Insert material (PEEK)
• Ingress protection rating (IP50 minimum)
• RoHS compliance status (ROHS3)

The substitute part S20L0C-P09MCC0-320S meets these core electrical and mechanical criteria, enabling functional equivalence in applications where connector interchangeability is required.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.0B.309.CLAD31Z and S20L0C-P09MCC0-320S are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The substitute part S20L0C-P09MCC0-320S provides equivalent electrical and mechanical functionality for 9-position solder cup circular connector applications with push-pull fastening and shielding.

Selection between these parts should account for the following documented differences: the ODU substitute supports a higher current rating of 4A compared to the LEMO original's 2A specification, and operates within a narrower temperature range of -40°C to 120°C versus the original's -55°C to 250°C. The ODU part features chrome over nickel shell finish compared to the LEMO's chrome finish, and includes integrated strain relief in addition to backshell features.

Frequently Asked Questions (FAQ)

Q: Can S20L0C-P09MCC0-320S be used as a direct replacement for FGG.0B.309.CLAD31Z?

A: Yes, for applications operating within the temperature range of -40°C to 120°C and requiring current ratings up to 4A. Both connectors share identical pin count, termination method, fastening type, shielding configuration, and contact finish specifications.

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

A: The primary differences are operating temperature range (LEMO: -55°C to 250°C; ODU: -40°C to 120°C), current rating (LEMO: 2A; ODU: 4A), shell finish (LEMO: Chrome; ODU: Chrome over Nickel), and integrated features (ODU includes strain relief).

Q: Are both parts RoHS compliant?

A: Yes, both FGG.0B.309.CLAD31Z and S20L0C-P09MCC0-320S are ROHS3 compliant and REACH unaffected.

Q: What is the cable opening specification for each connector?

A: FGG.0B.309.CLAD31Z: 0.091" ~ 0.126" (2.30mm ~ 3.20mm); S20L0C-P09MCC0-320S: 0.079" ~ 0.126" (2.00mm ~ 3.20mm).

Q: Do both connectors support the same ingress protection rating?

A: Yes, both connectors provide IP50 ingress protection (dust protected).
