FGA.1B.308.CLAD76 Equivalent & Substitute Parts

Part Overview

The FGA.1B.308.CLAD76 is an 8-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 984 units available. 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 when design requirements permit alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

The substitute part S11LAC-P08MFG0-7700 (ODU MINI-SNAP® L series) qualifies as an equivalent based on the following alignment of critical parameters:

Matching Parameters:

• 8-position connector configuration
• Male pin plug connector type
• Solder cup termination method
• Push-pull fastening mechanism
• Shielded design with backshell
• Brass shell material with chrome plating
• Gold-plated mating contacts
• PEEK insert material
• IP50 ingress protection rating
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity level
• EAR99 export classification
• Identical HTSUS code (8536.69.4020)

Allowable Parameter Variations: The substitute part operates within acceptable mechanical and electrical tolerances for this connector category. The cable opening range (0.276" ~ 0.303" vs. 0.283" ~ 0.299") overlaps sufficiently for standard cable gauges. The current rating of 7.5A exceeds the 5A requirement, providing additional capacity margin. Operating temperature range differs (-40°C ~ 120°C vs. -55°C ~ 250°C); substitution is valid only for applications within the narrower temperature window.

Parameter Comparison

Engineering Selection Recommendations

Both connectors maintain active product status and full ROHS3 compliance with identical export classifications. The FGA.1B.308.CLAD76 is specified for extended temperature operation (-55°C to 250°C), while the S11LAC-P08MFG0-7700 operates within -40°C to 120°C. Selection between these parts depends on application temperature requirements. The ODU substitute provides higher current capacity (7.5A vs. 5A), which is advantageous for power-dense applications. Both parts feature identical contact materials, finishes, and insert composition, ensuring electrical performance consistency. The cable opening specifications overlap within standard tolerance bands, permitting equivalent cable termination practices. Substitution is valid only when the application temperature profile remains within the narrower ODU operating window.

Frequently Asked Questions (FAQ)

Q: Can the S11LAC-P08MFG0-7700 replace the FGA.1B.308.CLAD76 in all applications?

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

Q: Are the solder cup terminations mechanically compatible?

A: Both connectors use solder cup termination with overlapping cable opening ranges (7.00mm ~ 7.70mm vs. 7.20mm ~ 7.60mm). Standard cable gauges compatible with the LEMO connector will accommodate the ODU connector within normal manufacturing tolerances.

Q: What is the difference in shell finish between the two parts?

A: The LEMO part uses chrome plating directly on brass. The ODU part uses chrome plating over a nickel underplate. Both finishes provide equivalent corrosion resistance and electrical conductivity for this connector class.

Q: Does the higher current rating of the ODU part affect compatibility?

A: No. The 7.5A rating of the ODU connector exceeds the 5A requirement of the LEMO specification. This provides additional capacity margin and does not compromise compatibility in applications designed for 5A operation.

Q: Are both parts compliant with the same regulatory standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What are the key parameters that determine substitution eligibility?

A: Critical parameters include 8-position configuration, male pin plug type, solder cup termination, push-pull fastening, shielded design, brass shell with gold-plated contacts, PEEK inserts, and IP50 protection. Operating temperature range is the primary limiting factor for substitution decisions.
