Both parts are suitable for direct substitution in through-hole radial mounting applications with identical PCB footprints and lead spacing.

Frequently Asked Questions (FAQ)

Q: Can TAP225K050HSB replace TAP225M050HSB in existing designs?

A: Yes. The TAP225K050HSB is a direct substitute with identical electrical ratings, physical dimensions, and mounting characteristics. The only difference is improved tolerance (±10% versus ±20%), which does not affect mechanical compatibility or circuit board layout.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal 2.2 µF value. TAP225M050HSB allows ±20% deviation (1.76 µF to 2.64 µF), while TAP225K050HSB allows ±10% deviation (1.98 µF to 2.42 µF). Applications with strict capacitance requirements benefit from the tighter tolerance of TAP225K050HSB.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical radial package dimensions: 0.217" diameter (5.50 mm), maximum seated height of 0.413" (10.50 mm), and lead spacing of 0.250" (6.35 mm). PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP225M050HSB and TAP225K050HSB are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements.

Q: What is the ESR specification and why is it identical in both parts?

A: ESR (Equivalent Series Resistance) of 4.6 Ohm represents the internal resistance of the capacitor at operating frequency. Both parts share identical ESR, ensuring equivalent performance in high-frequency filtering and energy storage applications.
