TAP476K010SCS Equivalent & Substitute Parts

Part Overview

The TAP476K010SCS is a 47 µF conformal coated tantalum capacitor rated at 10 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is in active production status and designed for general-purpose applications requiring reliable energy storage in compact form factors. Substitute parts may be necessary due to inventory constraints, lead time requirements, or specific packaging preferences while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP476K010SCS is determined by strict equivalence across the following parameters:

Capacitance value: 47 µF (exact match required)
Voltage rating: 10 V (exact match required)
Tolerance: ±10% (exact match required)
Type: Conformal coated tantalum (exact match required)
Mounting: Through hole radial configuration (exact match required)
Operating temperature range: -55°C to 125°C (exact match required)
Lifetime specification: 1000 hours @ 85°C (exact match required)

All three substitute parts meet these core electrical and mechanical criteria. Physical dimensions and lead spacing may vary within acceptable PCB layout tolerances. Packaging format (bulk vs. cut tape) does not affect electrical performance or functional compatibility.

Engineering Selection Recommendations

All three substitute parts maintain active production status and meet the core electrical specifications of the TAP476K010SCS. Selection should be based on the following considerations:

TAP476K010BRW (KYOCERA AVX) is the manufacturer-recommended primary substitute, offering identical electrical characteristics and ROHS3 compliance. The primary difference is packaging format (cut tape vs. bulk), which affects procurement and assembly processes but not component performance.

199D476X9010D1V1E3 (Vishay Sprague TANTALEX™ 199D series) provides full electrical equivalence with ROHS3 compliance. Physical dimensions differ slightly (0.236" diameter vs. 0.256"), requiring PCB layout verification for lead spacing compatibility at 0.100" (2.54mm).

T350H476K010AS (KEMET T350 UltraDip II series) meets all electrical requirements but carries RoHS non-compliant status. This part is suitable only for applications where RoHS compliance is not mandated. Physical dimensions are larger (0.299" diameter), requiring PCB layout confirmation.

Frequently Asked Questions (FAQ)

Q: Can TAP476K010BRW be used as a direct replacement for TAP476K010SCS?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (47 µF, 10 V, ±10%, 1.7 Ohm ESR, ROHS3 compliant). The only difference is packaging format (cut tape vs. bulk), which does not affect electrical performance or PCB mounting compatibility.

Q: What is the primary difference between the Vishay Sprague 199D476X9010D1V1E3 and the KYOCERA AVX TAP476K010SCS?

A: Electrical specifications are equivalent. Physical dimensions differ: the Vishay part measures 0.236" diameter with 0.100" lead spacing, while the KYOCERA part measures 0.256" diameter with 0.098" lead spacing. PCB layout must be verified for lead hole positioning before substitution.

Q: Is the KEMET T350H476K010AS suitable for RoHS-regulated applications?

A: No. The T350H476K010AS is RoHS non-compliant, making it unsuitable for applications subject to RoHS directives. Use only in applications where RoHS compliance is not required. The TAP476K010BRW or 199D476X9010D1V1E3 are compliant alternatives.

Q: Do all substitute parts have the same ESR specification?

A: The TAP476K010SCS, TAP476K010BRW, and T350H476K010AS all specify 1.7 Ohm ESR. The Vishay 199D476X9010D1V1E3 does not provide an ESR specification in available documentation.

Q: Are there physical dimension constraints when substituting these parts?

A: Yes. While all parts are radial through-hole components, physical dimensions vary. The KYOCERA parts (TAP476K010SCS and TAP476K010BRW) are 0.256" diameter. The Vishay part is 0.236" diameter. The KEMET part is 0.299" diameter. Lead spacing also varies (0.098", 0.100", and 0.100" respectively). PCB layout must accommodate these variations.

Q: What is the inventory status of these parts?

A: TAP476K010SCS: 863 pcs. TAP476K010BRW: 1900 pcs. 199D476X9010D1V1E3: 1434 pcs. T350H476K010AS: 1817 pcs. All parts are listed as new original stock.
