FGA.0B.305.CLAD42Z Equivalent & Substitute Parts

Part Overview

The FGA.0B.305.CLAD42Z is a 5-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 874 units available. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility is required within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.0B.305.CLAD42Z is determined by the following core parameters:

• Connector type (Plug, Male Pins)
• Number of positions (5)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Contact finish (Gold plating)
• Shielding requirement (Shielded)
• Insert material (PEEK)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The substitute part S20LAC-P05MFG0-420S, manufactured by ODU, meets these core substitution criteria. Both parts share identical connector topology, termination, fastening, and material specifications. Differences in operating temperature range, current rating, and cable opening dimensions are noted in the parameter comparison and must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.305.CLAD42Z and S20LAC-P05MFG0-420S are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The FGA.0B.305.CLAD42Z supports an extended operating temperature range of -55°C to 250°C, making it suitable for high-temperature applications. The S20LAC-P05MFG0-420S operates within -40°C to 120°C, which is appropriate for standard industrial and medical environments.

The S20LAC-P05MFG0-420S provides a higher current rating of 7.5A compared to 6.5A for the FGA.0B.305.CLAD42Z, and includes integrated strain relief in addition to the backshell. Cable opening dimensions differ slightly between the two parts; the ODU part accommodates cables from 3.00mm minimum diameter versus 3.20mm for the LEMO part.

Selection between these parts depends on application-specific requirements for temperature range, current capacity, and cable diameter compatibility. Both parts maintain identical connector topology, termination method, and contact specifications.

Frequently Asked Questions (FAQ)

Q: Can the S20LAC-P05MFG0-420S be used as a direct replacement for the FGA.0B.305.CLAD42Z?

A: Both connectors share the same 5-position male plug configuration with solder cup termination and push-pull fastening. Substitution is possible when application requirements fall within the operating temperature range of -40°C to 120°C and current demands do not exceed 7.5A. Cable diameter compatibility must be verified against the specified cable opening ranges.

Q: What are the key differences between these two connector models?

A: The primary differences are operating temperature range (FGA.0B.305.CLAD42Z: -55°C to 250°C versus S20LAC-P05MFG0-420S: -40°C to 120°C), current rating (6.5A versus 7.5A), cable opening dimensions (3.20mm–4.20mm versus 3.00mm–4.20mm), and shell finish (Chrome versus 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 FGA.0B.305.CLAD42Z and S20LAC-P05MFG0-420S are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of the cable opening specification?

A: Cable opening dimensions define the range of cable diameters that can be accommodated by the connector's solder cup termination. The FGA.0B.305.CLAD42Z accepts cables from 3.20mm to 4.20mm, while the S20LAC-P05MFG0-420S accepts cables from 3.00mm to 4.20mm. Cable diameter must fall within the specified range for proper mechanical and electrical connection.

Q: Can these connectors be used in high-temperature applications?

A: The FGA.0B.305.CLAD42Z is rated for -55°C to 250°C and is suitable for high-temperature applications. The S20LAC-P05MFG0-420S operates within -40°C to 120°C and is not recommended for high-temperature environments exceeding 120°C.
