TAP476K006SCS Equivalent & Substitute Parts

Part Overview

The TAP476K006SCS is a 47 µF conformal coated tantalum capacitor rated at 6.3 V with ±10% tolerance, manufactured by KYOCERA AVX. This radial through-hole component is designed for general-purpose applications requiring reliable energy storage in compact form factors. The part is currently active in production with full ROHS3 compliance and REACH unaffected status. Substitute parts are identified when design requirements allow for voltage rating upgrades, tolerance relaxation, or when inventory constraints necessitate alternative sourcing from the same manufacturer's product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP476K006SCS is determined by the following criteria:

Capacitance: Must remain 47 µF. No deviation is permitted.

Mounting Type & Package: Must remain Through Hole Radial configuration to ensure PCB compatibility without redesign.

Operating Temperature Range: Must maintain -55°C ~ 125°C minimum specification.

Voltage Rating: Substitutes may have equal or higher voltage ratings. A higher voltage rating provides design margin and is electrically compatible in applications rated at 6.3 V or below.

Tolerance: Substitutes may have equal or relaxed (wider) tolerance specifications (±10% or ±20%). Tighter tolerance is not required for general-purpose applications.

ESR: Substitutes with equal or lower ESR values are acceptable, as lower ESR improves performance characteristics.

Type & Compliance: Must maintain Conformal Coated type, ROHS3 compliance, and REACH unaffected status.

Based on these criteria, two substitute parts are identified:

• TAP476K010SCS: Voltage upgrade (10 V) with improved ESR (1.7 Ohm) and same tolerance (±10%).
• TAP476M006SCS: Tolerance relaxation (±20%) with same voltage (6.3 V) and ESR (2 Ohm).

Parameter Comparison

Engineering Selection Recommendations

TAP476K010SCS (Upgrade Option): This substitute provides a higher voltage rating (10 V) while maintaining ±10% tolerance and reducing ESR to 1.7 Ohm. The physical diameter increases from 6.00mm to 6.50mm; verify PCB layout clearance before selection. This part is suitable when design margins for voltage stress reduction are desired or when the application environment permits the slightly larger footprint. All compliance certifications remain equivalent.

TAP476M006SCS (MFR Recommended Option): This substitute maintains the original 6.3 V voltage rating and 6.00mm diameter but relaxes tolerance to ±20%. ESR remains at 2 Ohm. This part is suitable for applications where capacitance tolerance of ±20% is acceptable and where the original voltage and physical specifications must be preserved. All compliance certifications remain equivalent.

Both substitutes are manufactured by KYOCERA AVX with active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can TAP476K010SCS be used as a direct replacement for TAP476K006SCS?

A: TAP476K010SCS is electrically compatible as a substitute. The 10 V rating is higher than the 6.3 V requirement, providing design margin. However, the physical diameter increases from 6.00mm to 6.50mm. Verify PCB layout clearance before implementation.

Q: What is the difference between TAP476K006SCS and TAP476M006SCS?

A: Both parts share identical voltage (6.3 V), capacitance (47 µF), ESR (2 Ohm), and physical dimensions. The difference is tolerance: TAP476K006SCS is ±10%, while TAP476M006SCS is ±20%. Select TAP476M006SCS when ±20% tolerance is acceptable for your application.

Q: Are all three parts ROHS3 compliant?

A: Yes. TAP476K006SCS, TAP476K010SCS, and TAP476M006SCS are all ROHS3 compliant and REACH unaffected.

Q: Does the higher voltage rating of TAP476K010SCS affect performance in a 6.3 V application?

A: No. A higher voltage rating does not degrade performance in lower voltage applications. The 10 V rating provides additional design margin and stress reduction.

Q: Can TAP476M006SCS be used where ±10% tolerance is required?

A: No. TAP476M006SCS has ±20% tolerance and does not meet ±10% tolerance specifications. Use TAP476K006SCS or TAP476K010SCS for ±10% tolerance requirements.

Q: Are the lead spacings identical across all three parts?

A: Yes. All three parts maintain 0.098" (2.50mm) lead spacing, ensuring PCB footprint compatibility.
