FGG.0B.306.CLAD31Z Equivalent & Substitute Parts

Part Overview

The FGG.0B.306.CLAD31Z is a 6-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector is classified as a shielded, push-pull fastening connector with gold-plated mating contacts and chrome-finished brass shell. The part is currently active in production with 1106 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the original part may be unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.0B.306.CLAD31Z is determined by the following critical parameters:

Connector Type & Position Count: Plug configuration with 6 male pins
Termination Method: Solder cup termination
Fastening Mechanism: Push-pull coupling
Electrical Properties: Gold-plated mating contacts, shielded design
Material Composition: Brass shell with chrome finish
Environmental Rating: IP50 ingress protection, shielded construction
Compliance: ROHS3 compliant, REACH unaffected

The substitute part S20L0C-P06MCC0-320S from ODU meets these core substitution criteria. Both parts share identical connector type, position count, termination method, fastening type, contact finish, shielding, and compliance status. Variations in operating temperature range and current rating are documented in the parameter comparison table below.

Engineering Selection Recommendations

Both the FGG.0B.306.CLAD31Z and S20L0C-P06MCC0-320S are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The FGG.0B.306.CLAD31Z supports an extended operating temperature range of -55°C to 250°C, making it suitable for high-temperature applications. The S20L0C-P06MCC0-320S operates within -40°C to 120°C and provides a higher current rating of 4A compared to 2.5A for the LEMO part. The ODU substitute includes integrated strain relief in addition to the backshell feature.

Both connectors maintain identical electrical and mechanical interface specifications: 6-position male pin configuration, solder cup termination, push-pull fastening, gold-plated contacts, shielded design, and IP50 ingress protection. The choice between these parts should be based on the specific thermal and current requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the S20L0C-P06MCC0-320S directly replace the FGG.0B.306.CLAD31Z?

A: Yes, for applications operating within -40°C to 120°C and requiring up to 4A current. Both parts share identical connector type, pin count, termination method, fastening mechanism, and contact finish. Verify that your application does not require the extended temperature range of -55°C to 250°C provided by the LEMO part.

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: 2.5A; ODU: 4A), and shell finish (LEMO: Chrome; ODU: Chrome over Nickel). The ODU part includes strain relief as an additional feature.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the FGG.0B.306.CLAD31Z and S20L0C-P06MCC0-320S are ROHS3 compliant and REACH unaffected.

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

A: FGG.0B.306.CLAD31Z: 0.091" ~ 0.126" (2.30mm ~ 3.20mm). S20L0C-P06MCC0-320S: 0.079" ~ 0.126" (2.00mm ~ 3.20mm). Verify cable diameter compatibility with your application.

Q: Do both connectors support solder cup termination?

A: Yes. Both parts use solder cup termination for direct wire attachment.

Q: What is the ingress protection rating for both connectors?

A: Both connectors are rated IP50 - Dust Protected, providing equivalent environmental sealing.
