TAP476K020SCS Equivalent & Substitute Parts

Part Overview

The TAP476K020SCS is a 47 µF conformal coated tantalum capacitor rated at 20 V with ±10% tolerance, manufactured by KYOCERA AVX. This radial through-hole component is designed for general-purpose applications requiring stable capacitance performance across the operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification. Substitute parts may be required due to inventory constraints, application voltage derating requirements, or tolerance specifications that better suit specific circuit design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP476K020SCS is determined by the following critical parameters: capacitance value (47 µF), mounting type (through hole radial), conformal coating type, operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, REACH unaffected).

The identified substitute parts maintain the same capacitance value and physical mounting configuration. However, substitution introduces variations in voltage rating and tolerance specification:

TAP476K006SCS: Maintains 47 µF capacitance, ±10% tolerance, and conformal coating. Voltage rating is reduced to 6.3 V with ESR of 2 Ohm. Physical dimensions are smaller (0.236" Dia, 10.00mm height).

TAP476M006SCS: Maintains 47 µF capacitance and conformal coating at 6.3 V rating. Tolerance is widened to ±20% with ESR of 2 Ohm. Physical dimensions match TAP476K006SCS (0.236" Dia, 10.00mm height).

All substitute parts retain the same operating temperature range, lead spacing (0.098"), and compliance status as the main part.

Parameter Comparison

Engineering Selection Recommendations

Selection between the main part and substitute parts is determined by circuit voltage requirements and tolerance specifications:

TAP476K020SCS is the primary selection for applications requiring 20 V rated voltage with ±10% capacitance tolerance and 1.2 Ohm ESR performance.

TAP476K006SCS is applicable only in circuits where the maximum operating voltage does not exceed 6.3 V. This part maintains ±10% tolerance matching the main part specification. The increased ESR of 2 Ohm must be evaluated against circuit ripple current and thermal dissipation requirements. The reduced physical dimensions (0.236" Dia, 10.00mm height) may provide board layout advantages in space-constrained applications.

TAP476M006SCS is applicable only in circuits where the maximum operating voltage does not exceed 6.3 V and where ±20% capacitance tolerance is acceptable. This part shares the same physical dimensions and ESR characteristics as TAP476K006SCS. Selection of this part should be limited to applications where the wider tolerance does not compromise circuit performance.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the main part.

Frequently Asked Questions (FAQ)

Q: Can TAP476K006SCS or TAP476M006SCS be used in a 20 V circuit?

A: No. Both substitute parts are rated at 6.3 V maximum. Using these parts in a 20 V circuit will result in component failure. Voltage rating is a non-negotiable substitution parameter.

Q: What is the difference between TAP476K006SCS and TAP476M006SCS?

A: Both parts share identical voltage rating (6.3 V), capacitance (47 µF), physical dimensions, and ESR (2 Ohm). The difference is tolerance specification: TAP476K006SCS is ±10%, while TAP476M006SCS is ±20%. Selection depends on circuit tolerance requirements.

Q: Are the physical dimensions of substitute parts compatible with the PCB footprint designed for TAP476K020SCS?

A: The substitute parts (TAP476K006SCS and TAP476M006SCS) have smaller physical dimensions (0.236" Dia vs. 0.335" Dia, 10.00mm height vs. 12.50mm height). Lead spacing remains identical at 0.098" (2.50mm). PCB footprints designed for the larger TAP476K020SCS will accommodate the smaller substitute parts, but the reverse is not true. Board layout verification is required.

Q: Do all parts share the same operating temperature range?

A: Yes. TAP476K020SCS, TAP476K006SCS, and TAP476M006SCS all operate across -55°C to 125°C with 1000 hours lifetime at 85°C.

Q: Are there compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant and REACH unaffected, providing regulatory equivalence.

Q: How does ESR difference affect circuit performance?

A: TAP476K020SCS has 1.2 Ohm ESR, while both substitute parts have 2 Ohm ESR. Higher ESR increases impedance and thermal dissipation under ripple current conditions. Circuit analysis is required to determine if the increased ESR is acceptable for the intended application.
