Key Parameters

Substitute Part Grouping Explanation

Substitution of the S-812C27AMC-C2HT2G is determined by strict equivalence across the following critical parameters:

• Output voltage specification (2.7V fixed)
• Output current capability (30mA minimum)
• Input voltage rating (16V maximum)
• Voltage dropout characteristics (0.68V @ 10mA)
• Quiescent current performance (500 nA)
• Operating temperature range (-40°C to 85°C)
• Package and pinout compatibility (SOT-23-5)
• Regulatory compliance (ROHS3, REACH Unaffected)

The S-812C27AMC-C2HT2U meets all these criteria as a parametric equivalent from the same S-812C series, with identical electrical specifications and package configuration. The primary distinction is product lifecycle status: the substitute part maintains Active status, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations
