TAP474K035SCS Equivalent & Substitute Parts

Part Overview

The TAP474K035SCS is a 0.47 µF conformal coated tantalum capacitor rated for 35 V operation in a radial through-hole package. Manufactured by KYOCERA AVX, this component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts may be required due to inventory constraints, supply chain discontinuities, or design flexibility needs while maintaining equivalent electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP474K035SCS is determined by the following critical parameters:

Capacitance value: 0.47 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage rating: 35 V minimum (equal or higher acceptable)
Type: Conformal Coated (exact match required)
Mounting: Through Hole Radial (exact match required)
Operating temperature range: -55°C ~ 125°C (exact match required)
Package size code: A (exact match required)

Substitute parts are grouped into two categories: direct equivalents (matching all parameters including voltage rating) and upgraded alternatives (higher voltage rating with identical capacitance and tolerance).

Engineering Selection Recommendations

TAP474K050SCS (KYOCERA AVX): This upgrade substitute provides identical capacitance and tolerance with an increased voltage rating of 50 V. All electrical and mechanical parameters remain equivalent to the main part, with identical ESR, operating temperature range, and physical dimensions. This part is ROHS3 compliant and maintains Active product status. Selection of this upgrade is appropriate for applications where higher voltage margin is beneficial.

199D474X9035A1V1E3 (Vishay Sprague TANTALEX™ 199D Series): This direct equivalent matches the 35 V voltage rating and all critical electrical parameters. Physical dimensions show minor variations in diameter (0.173" vs 0.177") and lead spacing (0.100" vs 0.098"), which remain within acceptable mechanical tolerances for standard through-hole PCB layouts. ESR is not specified for this part. ROHS3 compliance and Active product status are maintained.

T350A474K035AS (KEMET T350 UltraDip II Series): This direct equivalent matches the 35 V voltage rating, capacitance, tolerance, and ESR specifications. Physical dimensions show minor variations in height (0.280" vs 0.276") and lead spacing (0.100" vs 0.098"). This part carries RoHS non-compliant status, which may restrict use in applications with RoHS compliance requirements. Product status is Active.

Frequently Asked Questions (FAQ)

Q: Can TAP474K050SCS be used as a direct replacement for TAP474K035SCS?

A: Yes. The TAP474K050SCS is a direct mechanical and electrical substitute with identical capacitance (0.47 µF), tolerance (±10%), ESR (13 Ohm), and physical dimensions. The higher voltage rating (50 V vs 35 V) provides additional design margin without affecting circuit performance in applications rated for 35 V operation.

Q: Are there mechanical compatibility concerns with 199D474X9035A1V1E3?

A: Minor dimensional variations exist. The 199D474X9035A1V1E3 has a slightly smaller diameter (4.40mm vs 4.50mm) and different lead spacing (2.54mm vs 2.50mm). These variations are within standard through-hole PCB tolerances and do not prevent board-level substitution.

Q: What is the compliance difference between substitute parts?

A: TAP474K050SCS and 199D474X9035A1V1E3 are both ROHS3 compliant. T350A474K035AS is RoHS non-compliant. Selection should be based on application compliance requirements.

Q: Does ESR specification affect substitution eligibility?

A: The 199D474X9035A1V1E3 does not specify ESR in the provided data. Both TAP474K035SCS and T350A474K035AS specify 13 Ohm ESR. For applications where ESR is a critical parameter, TAP474K050SCS or T350A474K035AS are preferred.

Q: Are all substitute parts currently in stock?

A: Inventory status at time of reference: TAP474K035SCS (1562 pcs), TAP474K050SCS (2321 pcs), 199D474X9035A1V1E3 (934 pcs), T350A474K035AS (1061 pcs).
