TAP225K020CCS Equivalent & Substitute Parts

Part Overview

The TAP225K020CCS is a 2.2 µF conformal coated tantalum capacitor rated at 20 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is part of the TAP series and maintains active product status. Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage rating or ESR characteristics differ, enabling component selection flexibility for circuit design requirements and supply chain optimization.

Substitute Part Grouping Explanation

Substitution for the TAP225K020CCS is determined by maintaining the following critical parameters:

• Capacitance Value: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Physical Dimensions: 0.177" Dia (4.50 mm), Height 0.335" (8.50 mm), Lead Spacing 0.197" (5.00 mm) (exact match required)
• Type: Conformal Coated (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Voltage rating and ESR may vary within the substitute group. A higher voltage rating (25 V) provides enhanced voltage margin while maintaining identical physical form factor and electrical characteristics. ESR reduction from 7 Ohm to 6 Ohm represents improved performance in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP225K020CCS and TAP225K025CCS maintain active product status and full compliance with ROHS3 and REACH regulations. The TAP225K025CCS provides a higher voltage rating (25 V versus 20 V) with identical physical dimensions and improved ESR performance (6 Ohm versus 7 Ohm). Selection between these parts depends on circuit voltage requirements and performance specifications. Both components are suitable for applications requiring conformal coated tantalum capacitors with radial through-hole mounting in the 2.2 µF capacitance range.

Frequently Asked Questions (FAQ)

Q: Can TAP225K025CCS replace TAP225K020CCS in all applications?

A: TAP225K025CCS is a direct physical and functional substitute for TAP225K020CCS. The higher voltage rating (25 V) is compatible with circuits designed for 20 V operation. Verify that circuit design does not depend on the specific ESR value of 7 Ohm; the substitute part provides 6 Ohm ESR.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.177" diameter (4.50 mm), 0.335" maximum seated height (8.50 mm), and 0.197" lead spacing (5.00 mm). Both use radial through-hole mounting with manufacturer size code A.

Q: What is the significance of the conformal coating?

A: Conformal coating provides environmental protection for the tantalum capacitor. Both substitute parts maintain this coating type, ensuring equivalent environmental performance and reliability characteristics.

Q: Do these parts have different temperature operating ranges?

A: No. Both TAP225K020CCS and TAP225K025CCS operate across the identical temperature range of -55°C to 125°C with 1000 hours lifetime at 85°C.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, with identical regulatory status.
