Substitute Part Grouping Explanation

The TAP225K025SCS qualifies as a direct substitute based on the following criteria:

Matching Parameters:

• Capacitance: 2.2 µF (identical)
• Tolerance: ±10% (identical)
• Type: Conformal Coated (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Physical Dimensions: 0.177" Dia (4.50mm), Height 0.276" (7.00mm), Lead Spacing 0.098" (2.50mm) (identical)
• Manufacturer Size Code: A (identical)
• RoHS Status: ROHS3 Compliant (identical)

Upgrade Parameter:

• Voltage - Rated: 25 V (upgraded from 20 V)
• ESR: 6 Ohm (improved from 7 Ohm)

The TAP225K025SCS provides higher voltage rating and lower ESR while maintaining all other electrical and mechanical specifications, making it suitable for applications requiring enhanced voltage margin or improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both TAP225K020SCS and TAP225K025SCS are active products with ROHS3 compliance and REACH unaffected status. The TAP225K025SCS is suitable for direct substitution in applications where the original 20 V rating is specified, as it provides a higher voltage margin (25 V) and improved ESR performance (6 Ohm versus 7 Ohm). Both components maintain identical physical dimensions, lead spacing, and thermal operating range, ensuring PCB compatibility without layout modifications. Selection between these parts should be based on circuit voltage requirements and performance specifications.

Frequently Asked Questions (FAQ)

Q: Can TAP225K025SCS replace TAP225K020SCS in existing designs?

A: Yes. The TAP225K025SCS is mechanically and electrically compatible. It maintains identical capacitance (2.2 µF), tolerance (±10%), physical dimensions, lead spacing, and operating temperature range. The higher voltage rating (25 V) and lower ESR (6 Ohm) represent performance improvements with no adverse effects on circuit operation.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both components use identical radial through-hole packages with 0.098" (2.50mm) lead spacing and 0.177" (4.50mm) diameter. No PCB modifications are required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP225K020SCS and TAP225K025SCS are ROHS3 compliant, REACH unaffected, and classified as EAR99 under export control regulations.

Q: What is the difference in ESR between these parts?

A: The TAP225K020SCS has 7 Ohm ESR, while the TAP225K025SCS has 6 Ohm ESR. The lower ESR of the substitute part provides improved high-frequency performance and reduced power dissipation.

Q: Are both parts rated for the same temperature range?

A: Yes. Both components operate across -55°C to 125°C with 1000 hours lifetime at 85°C.
