Engineering Selection Recommendations

Both TAP476M010SCS and TAP476K010SCS are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations.

Selection between these parts should be based on tolerance requirements. The TAP476M010SCS with ±20% tolerance is appropriate for applications where capacitance variation within this range does not impact circuit performance. The TAP476K010SCS with ±10% tolerance provides tighter capacitance accuracy for designs requiring more precise energy storage characteristics.

Both parts share identical electrical performance characteristics (ESR, voltage rating, temperature range, lifetime) and mechanical compatibility (footprint, lead spacing, mounting configuration), ensuring direct substitution capability at the board level.
