TAP475M035SCS Equivalent & Substitute Parts

Part Overview

The TAP475M035SCS is a 4.7 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 reliable energy storage in compact form factors. Alternative models may be required due to inventory constraints, design optimization for tolerance specifications, or voltage rating adjustments for specific circuit requirements.

Same voltage rating: 35 V
Same mounting type: Through Hole Radial
Same conformal coating type
Compatible operating temperature range: -55°C to 125°C
Same lifetime specification: 1000 Hrs @ 85°C

Secondary Substitutes (Tolerance Upgrade):

TAP475K035SCS meets all primary criteria with improved tolerance specification (±10% vs ±20%)

Functional Alternatives (Voltage Derating):

TAP475M010SCS provides the same capacitance and tolerance but at reduced voltage rating (10 V vs 35 V), suitable only for lower-voltage circuit applications

Cross-Manufacturer Equivalents:

199D475X0035C1V1E3 (Vishay Sprague) matches primary electrical and mechanical specifications

Engineering Selection Recommendations

TAP475K035SCS is the preferred direct substitute when available. It maintains identical electrical ratings (4.7 µF, 35 V) and mechanical compatibility while providing tighter tolerance specification (±10%), reducing circuit performance variation. Both parts are KYOCERA AVX products with Active status and full regulatory compliance.

199D475X0035C1V1E3 (Vishay Sprague TANTALEX™ series) provides cross-manufacturer equivalence with matching capacitance, voltage, and tolerance specifications. Physical dimensions are within acceptable tolerance for standard through-hole PCB layouts. This part is suitable for applications where multi-source qualification is required.

TAP475M010SCS is not a direct substitute due to reduced voltage rating (10 V vs 35 V). This part is applicable only in circuit designs where the operating voltage does not exceed 10 V. Use of this part in 35 V circuits will result in component failure.

All substitute options maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TAP475K035SCS replace TAP475M035SCS in all applications? A: Yes. TAP475K035SCS is a direct electrical and mechanical substitute with identical capacitance (4.7 µF), voltage rating (35 V), and physical package dimensions. The ±10% tolerance is tighter than the original ±20%, providing improved circuit performance consistency.

Q: Is TAP475M010SCS a suitable alternative? A: TAP475M010SCS is not suitable as a general substitute. While it shares the same capacitance value and tolerance, its 10 V voltage rating is insufficient for circuits designed for 35 V operation. This part is applicable only in designs with maximum operating voltages of 10 V or lower.

Q: What are the physical compatibility considerations for 199D475X0035C1V1E3? A: The Vishay Sprague part maintains compatible radial through-hole mounting with lead spacing of 0.100" (2.54mm) versus the KYOCERA AVX standard of 0.098" (2.50mm). Height difference is 0.360" (9.14mm) versus 0.354" (9.00mm). These minor variations are within standard PCB layout tolerances for through-hole applications.

Q: Are all substitute parts RoHS and REACH compliant? A: Yes. TAP475K035SCS, TAP475M010SCS, and 199D475X0035C1V1E3 are all ROHS3 Compliant and REACH Unaffected, matching the regulatory status of the original TAP475M035SCS.

Q: What is the difference in ESR between substitute options? A: TAP475M035SCS and TAP475K035SCS both specify 3 Ohm ESR. TAP475M010SCS specifies 8 Ohm ESR due to its lower voltage rating. The 199D475X0035C1V1E3 does not provide ESR specification in available documentation.
