FGA.1B.306.CLAD52Z Equivalent & Substitute Parts

Part Overview

The FGA.1B.306.CLAD52Z is a 6-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 part is currently active in production with 838 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit interchangeability based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FGA.1B.306.CLAD52Z with the S21LAC-P06MFG0-520S is based on the following critical parameters that must align for functional interchangeability:

• Connector Type & Position Count: Both are 6-position male plug connectors with identical pin configuration
• Termination Method: Both use solder cup termination for identical PCB integration
• Fastening Mechanism: Both employ push-pull fastening for mating and unmating
• Contact Material & Finish: Both feature brass contacts with gold plating on mating surfaces
• Shielding: Both are shielded connectors providing equivalent EMI protection
• Current Rating: Both support 7A or greater current capacity
• Insert Material: Both use PEEK for identical dielectric properties
• Ingress Protection: Both provide IP50 dust protection
• Compliance: Both are ROHS3 compliant and REACH unaffected

The S21LAC-P06MFG0-520S operates within a reduced temperature range (-40°C to 120°C) compared to the primary part. This substitution is valid only for applications where the operating temperature requirement does not exceed 120°C.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.306.CLAD52Z and S21LAC-P06MFG0-520S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The primary distinction between these parts is the operating temperature range. The LEMO FGA.1B.306.CLAD52Z supports -55°C to 250°C, while the ODU S21LAC-P06MFG0-520S supports -40°C to 120°C. Selection between these parts must be based on the specific operating temperature requirements of the application. For applications operating within -40°C to 120°C, both parts are functionally equivalent. For applications requiring operation below -40°C or above 120°C, the FGA.1B.306.CLAD52Z is the appropriate selection. The ODU part offers a slightly higher current rating of 7.5A compared to 7A for the LEMO part, and includes strain relief features not specified for the primary part.

Frequently Asked Questions (FAQ)

Q: Can the S21LAC-P06MFG0-520S be used as a direct replacement for the FGA.1B.306.CLAD52Z?

A: Direct substitution is valid only if the application operates within the temperature range of -40°C to 120°C. The ODU part has a narrower operating temperature range than the LEMO part. If your application requires operation outside this range, the FGA.1B.306.CLAD52Z must be used.

Q: What are the key compatibility factors between these two connectors?

A: Both connectors share identical pin count (6 positions), termination method (solder cup), fastening mechanism (push-pull), contact material and finish (brass with gold plating), shielding, and insert material (PEEK). These parameters ensure mechanical and electrical compatibility within the specified operating conditions.

Q: Are there differences in cable opening specifications?

A: Yes. The FGA.1B.306.CLAD52Z accepts cable diameters of 0.165" to 0.205" (4.20mm to 5.20mm), while the S21LAC-P06MFG0-520S accepts 0.157" to 0.205" (4.00mm to 5.20mm). The ODU part accommodates slightly smaller minimum cable diameters. Verify your cable diameter falls within the acceptable range for your selected connector.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the FGA.1B.306.CLAD52Z and S21LAC-P06MFG0-520S are ROHS3 compliant, REACH unaffected, and have MSL rating of 1 (Unlimited). Both carry ECCN EAR99 classification and HTSUS code 8536.69.4020.

Q: What is the difference in current rating between these parts?

A: The FGA.1B.306.CLAD52Z is rated for 7A, while the S21LAC-P06MFG0-520S is rated for 7.5A. Both ratings are suitable for typical signal and low-power applications. Verify your application current requirements against the selected part's rating.
