Engineering Selection Recommendations
The S-812C40AMC-C2UT2U is a direct parametric equivalent to the S-812C40AMC-C2UT2G. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
The primary distinction is product lifecycle status: the S-812C40AMC-C2UT2G is designated "Not For New Designs," while the S-812C40AMC-C2UT2U maintains "Active" status. For applications requiring long-term supply assurance and manufacturer support, the S-812C40AMC-C2UT2U is the preferred selection. Both parts are functionally interchangeable within the specified electrical and thermal operating parameters.
Frequently Asked Questions (FAQ)
Q: Can the S-812C40AMC-C2UT2U directly replace the S-812C40AMC-C2UT2G?
A: Yes. Both parts are parametric equivalents with identical output voltage (4V), output current (65mA), input voltage rating (16V), dropout voltage (0.3V @ 10mA), quiescent current (500 nA), operating temperature range (-40°C ~ 85°C), and SOT-23-5 package configuration. No circuit modifications are required.
Q: What is the difference between these two part numbers?
A: The electrical and physical specifications are identical. The S-812C40AMC-C2UT2G is marked "Not For New Designs," indicating end-of-life status, while the S-812C40AMC-C2UT2U is in active production. The suffix difference (UT2G vs. UT2U) reflects manufacturing date code or tape reel configuration variations.
Q: Are both parts compatible with the same PCB layout?
A: Yes. Both parts use the same SOT-23-5 (SC-74A) package with identical pin configuration and footprint. No PCB redesign is necessary for substitution.
Q: Do both parts meet the same compliance standards?
A: Yes. Both the S-812C40AMC-C2UT2G and S-812C40AMC-C2UT2U are ROHS3 compliant and REACH unaffected, with MSL rating of 1 (unlimited moisture sensitivity).
Q: Which part should be selected for new designs?
A: The S-812C40AMC-C2UT2U should be selected for new designs due to its active product status and assured long-term availability from ABLIC Inc.
