Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. The FGA.0B.304.CLAD56Z operates across a broader temperature range (-55°C to 250°C) compared to the S20LAC-P04MFG0-560S (-40°C to 120°C). Selection between these parts should be based on the specific operating temperature requirements of the application. The ODU substitute provides a marginally higher current rating of 7.5A versus 7A for the LEMO part. Both connectors are suitable for industrial, medical, military, and testing equipment applications where the operating temperature envelope of the selected part aligns with system requirements.

Frequently Asked Questions (FAQ)

Q: Can S20LAC-P04MFG0-560S be used as a direct replacement for FGA.0B.304.CLAD56Z?

A: The S20LAC-P04MFG0-560S is functionally equivalent 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 FGA.0B.304.CLAD56Z is the appropriate selection due to its extended operating temperature range.

Q: Are there differences in mechanical compatibility?

A: Both connectors use identical push-pull fastening and solder cup termination. Cable opening specifications differ slightly: FGA.0B.304.CLAD56Z accommodates 5.30mm to 5.60mm, while S20LAC-P04MFG0-560S accommodates 5.00mm to 5.60mm. Verify cable diameter compatibility with your specific application.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry MSL rating of 1 (Unlimited) and ECCN classification of EAR99.

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

A: The FGA.0B.304.CLAD56Z features chrome finish on brass, while the S20LAC-P04MFG0-560S features chrome over nickel on brass. Both provide equivalent corrosion protection and electrical performance for the specified applications.

Q: Are there current rating differences?

A: The S20LAC-P04MFG0-560S is rated for 7.5A compared to 7A for the FGA.0B.304.CLAD56Z. Both ratings are suitable for standard 4-position connector applications in the specified categories.
