Substitute Part Grouping Explanation

The TAP686K025CCS qualifies as a direct substitute for the TAP686K020CCS based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 68 µF (identical)
• Tolerance: ±10% (identical)
• Type: Conformal Coated (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Physical Dimensions: 0.354" Dia (9.00mm), Height 0.630" (16.00mm), Lead Spacing 0.197" (5.00mm) (identical)
• Series: TAP (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameters (Upgrade Characteristics):

• Voltage - Rated: 25 V (upgraded from 20 V)
• ESR: 800 mOhm (improved from 900 mOhm)

The TAP686K025CCS provides a higher voltage rating and lower ESR, making it suitable for applications where the original 20 V specification can accommodate a 25 V component without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP686K020CCS and TAP686K025CCS maintain Active product status and are ROHS3 compliant with REACH Unaffected designation, ensuring regulatory compliance for current and future applications. The TAP686K025CCS provides enhanced performance characteristics through increased voltage rating and reduced ESR while maintaining identical physical footprint and thermal operating range. Selection between these parts depends on circuit voltage requirements and performance margin specifications. Both components are suitable for general-purpose applications requiring conformal coating protection and stable capacitance performance.

Frequently Asked Questions (FAQ)

Q: Can TAP686K025CCS replace TAP686K020CCS in existing designs? A: Yes, the TAP686K025CCS is a direct physical and functional substitute. The higher 25 V rating provides additional voltage margin, and the lower 800 mOhm ESR improves performance. No PCB modifications are required due to identical radial package dimensions and lead spacing.

Q: What is the significance of the voltage rating difference? A: The TAP686K025CCS is rated for 25 V compared to the 20 V rating of the TAP686K020CCS. This higher rating allows operation in circuits with greater voltage headroom. If your circuit operates at or below 20 V, both parts are functionally equivalent; the 25 V part simply provides additional safety margin.

Q: Does the ESR difference affect circuit performance? A: The TAP686K025CCS has lower ESR (800 mOhm versus 900 mOhm). Lower ESR reduces voltage ripple and heat generation, particularly beneficial in high-frequency switching applications or circuits with stringent ripple specifications.

Q: Are the physical dimensions identical? A: Yes. Both parts share identical radial package dimensions: 0.354" diameter (9.00mm), 0.630" maximum seated height (16.00mm), and 0.197" lead spacing (5.00mm). Direct PCB substitution is possible without layout modifications.

Q: Do both parts meet the same compliance standards? A: Yes. Both TAP686K020CCS and TAP686K025CCS are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronics manufacturing and distribution.

Q: What is the operating temperature range for both parts? A: Both components operate across -55°C to 125°C with 1000 hours lifetime specification at 85°C, ensuring consistent performance across industrial and commercial temperature environments.
