Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.1B.316.CLAD52Z is determined by the following critical parameters:

• Connector Type & Pin Configuration: Plug with male pins, 16-position configuration
• Termination Method: Solder cup termination for direct wire attachment
• Fastening Mechanism: Push-pull coupling for secure mating
• Electrical Properties: Gold-plated mating contacts and shielded construction
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The substitute part S21LAC-P16MCC0-520S (ODU MINI-SNAP® L series) meets these core substitution criteria. Both connectors share identical connector type, pin count, termination method, fastening type, contact finish, shielding, and compliance certifications. Differences exist in shell size designation, operating temperature range, current rating, and backshell material specifications, which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.316.CLAD52Z and S21LAC-P16MCC0-520S are active products with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts must account for the following documented differences:

The LEMO FGA.1B.316.CLAD52Z supports an extended operating temperature range of -55°C to 250°C, making it suitable for high-temperature applications. The ODU S21LAC-P16MCC0-520S operates within -40°C to 120°C, limiting its use to standard industrial and commercial temperature environments.

The ODU substitute provides a higher current rating of 4A compared to the LEMO part's 1.5A rating. Applications requiring current levels between 1.5A and 4A per contact may benefit from the ODU option, provided temperature requirements remain within the -40°C to 120°C range.

Cable opening specifications differ slightly, with the ODU part accommodating cables from 4.00mm minimum diameter versus the LEMO part's 4.20mm minimum. This difference may impact cable assembly compatibility depending on specific cable gauge requirements.

Both connectors feature identical contact finish (gold), shielding, fastening mechanism (push-pull), and insert material (PEEK), ensuring functional compatibility in standard applications where temperature and current ratings are not limiting factors.

Frequently Asked Questions (FAQ)

Q: Can the ODU S21LAC-P16MCC0-520S directly replace the LEMO FGA.1B.316.CLAD52Z in all applications?

A: Direct replacement is possible only when application requirements fall within the ODU part's operating temperature range (-40°C to 120°C) and current rating (4A maximum per contact). Applications requiring temperatures below -40°C or above 120°C require the LEMO part's extended range.

Q: What are the key compatibility factors between these two 16-position connectors?

A: Both connectors share identical pin count (16), connector type (plug with male pins), termination method (solder cup), fastening mechanism (push-pull), contact finish (gold), shielding, and insert material (PEEK). These parameters ensure mechanical and electrical compatibility in standard applications.

Q: How do the cable opening specifications affect connector selection?

A: The LEMO part accommodates cables from 0.165" to 0.205" (4.20mm to 5.20mm), while the ODU part accepts 0.157" to 0.205" (4.00mm to 5.20mm). The ODU part supports slightly smaller minimum cable diameters. Verify cable gauge compatibility with your specific assembly requirements.

Q: Are both connectors suitable for regulated industries?

A: Yes. Both the LEMO FGA.1B.316.CLAD52Z and ODU S21LAC-P16MCC0-520S are ROHS3 compliant and REACH unaffected, meeting compliance requirements for regulated applications within their respective operating parameters.

Q: What is the primary limitation of the ODU substitute in high-temperature applications?

A: The ODU S21LAC-P16MCC0-520S operates only to 120°C maximum, whereas the LEMO FGA.1B.316.CLAD52Z supports continuous operation to 250°C. Applications requiring sustained operation above 120°C must use the LEMO part.
