TAP475K020SCS Equivalent & Substitute Parts

Part Overview

The TAP475K020SCS is a 4.7 µF conformal coated tantalum capacitor rated at 20 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is classified as Active product status and is designed for general purpose applications requiring reliable energy storage in compact form factors. Substitute parts become necessary when addressing specific application constraints such as board space limitations, voltage derating requirements, or inventory availability while maintaining functional equivalence within the allowed electrical and mechanical parameters of the TAP series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TAP series is determined by the following critical parameters:

• Capacitance Value: Must remain 4.7 µF (±10% tolerance maintained)
• Mounting Type: Must be Through Hole radial configuration
• Series Family: Must belong to KYOCERA AVX TAP conformal coated tantalum capacitor series
• Operating Temperature Range: Must support -55°C ~ 125°C
• Compliance Standards: Must maintain ROHS3 compliance and REACH unaffected status

The TAP475K006SCS qualifies as a substitute based on matching capacitance, tolerance, mounting type, temperature range, and compliance certifications. The primary difference is the rated voltage (6.3 V versus 20 V), which represents a lower voltage rating suitable for applications with reduced voltage requirements or where voltage derating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both TAP475K020SCS and TAP475K006SCS maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts is determined by circuit voltage requirements. The TAP475K020SCS is specified for applications requiring 20 V rated voltage operation. The TAP475K006SCS is suitable for circuits operating at 6.3 V or lower, offering a smaller physical footprint (0.177" diameter versus 0.197" diameter) and reduced height (0.276" versus 0.335" seated maximum). The TAP475K006SCS exhibits higher ESR (10 Ohm versus 4.5 Ohm), which may impact performance in applications sensitive to impedance characteristics. Both parts share identical lead spacing (0.098" / 2.50mm), supporting direct PCB footprint compatibility when voltage and ESR specifications permit substitution.

Frequently Asked Questions (FAQ)

Q: Can TAP475K006SCS replace TAP475K020SCS in all applications?

A: No. The TAP475K006SCS is rated for 6.3 V maximum. It is suitable only for circuits operating at or below 6.3 V. Applications requiring 20 V operation must use TAP475K020SCS or equivalent 20 V rated parts.

Q: What is the impact of higher ESR in the TAP475K006SCS?

A: The TAP475K006SCS has 10 Ohm ESR compared to 4.5 Ohm in the TAP475K020SCS. Higher ESR increases impedance and heat dissipation. Applications sensitive to ripple current or operating at high frequencies may experience performance degradation with the substitute part.

Q: Are the physical dimensions compatible for PCB layout?

A: Lead spacing is identical (0.098" / 2.50mm) for both parts, supporting direct footprint compatibility. However, the TAP475K006SCS is smaller in diameter (0.177" versus 0.197") and height (0.276" versus 0.335"), which may provide board space advantages in constrained layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP475K020SCS and TAP475K006SCS are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the capacitance tolerance for both parts?

A: Both parts maintain ±10% capacitance tolerance, ensuring equivalent energy storage characteristics within specified limits.

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

A: Yes. Both parts operate across -55°C to 125°C with 1000 hour lifetime at 85°C, supporting identical thermal performance specifications.
