Parameter Comparison

Engineering Selection Recommendations

Both TAP474M035FCS and TAP474K035CCS maintain Active product status and full ROHS3 compliance. The TAP474K035CCS provides superior tolerance performance at ±10% versus ±20%, making it suitable for applications requiring tighter capacitance accuracy. Both components share identical electrical ratings, thermal characteristics, and physical form factors, ensuring direct functional equivalence in through-hole radial mounting applications. Selection between these parts should be based on tolerance requirements specific to the circuit design.

Frequently Asked Questions (FAQ)

Q: Can TAP474K035CCS replace TAP474M035FCS in existing designs?

A: Yes. Both components are electrically and mechanically identical except for tolerance specification. The TAP474K035CCS operates at ±10% tolerance compared to ±20% for the TAP474M035FCS, representing an upgrade in capacitance accuracy. No PCB modifications are required.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable deviation of actual capacitance from the nominal 0.47 µF value. The TAP474M035FCS allows ±20% deviation (0.376 µF to 0.564 µF), while TAP474K035CCS allows ±10% deviation (0.423 µF to 0.517 µF). Applications requiring tighter capacitance control should specify the ±10% variant.

Q: Are the physical dimensions identical?

A: Yes. Both components use identical radial through-hole packaging with Size Code A designation, 0.177" diameter, 0.335" maximum seated height, and 0.197" lead spacing. Direct board-level substitution is possible without layout modifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP474M035FCS and TAP474K035CCS are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.
