TAP476K025SCS Equivalent & Substitute Parts

Part Overview

The TAP476K025SCS is a 47 µF conformal coated tantalum capacitor rated at 25 V with ±10% tolerance, manufactured by KYOCERA AVX. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and maintains 1000 hours lifetime at 85°C. Substitute parts are identified when application voltage requirements are lower or tolerance specifications can be relaxed without compromising circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAP476K025SCS is valid when the following conditions are met:

Mandatory Matching Parameters:

• Capacitance: 47 µF (exact match required)
• Mounting Type: Through Hole Radial (physical compatibility)
• Lead Spacing: 0.098" (2.50 mm) (PCB layout compatibility)
• Type: Conformal Coated Tantalum (environmental and reliability requirements)
• Operating Temperature Range: -55°C to 125°C (thermal compatibility)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Allowable Variations:

• Voltage Rating: May be reduced if circuit maximum voltage does not exceed the substitute part rating
• Tolerance: May be increased (±10% to ±20%) if circuit design permits wider capacitance variation
• ESR: May increase if circuit impedance requirements are not exceeded
• Package Size: May be smaller if physical space permits

The identified substitutes TAP476K006SCS and TAP476M006SCS both operate at 6.3 V, which is lower than the 25 V rating of the main part. These substitutes are valid only in applications where the actual operating voltage does not exceed 6.3 V.

Parameter Comparison

Engineering Selection Recommendations

TAP476K025SCS is the primary selection for applications requiring a 25 V rated capacitor with ±10% tolerance. This part maintains the highest voltage margin and tightest tolerance specification.

TAP476K006SCS is a valid substitute when circuit design confirms that the maximum operating voltage does not exceed 6.3 V. This part maintains ±10% tolerance matching the main part and reduces physical footprint due to smaller package size (F code). ESR increases to 2 Ohm; verify that circuit impedance requirements are not exceeded.

TAP476M006SCS is a valid substitute under the same voltage constraint (maximum 6.3 V) with the additional allowance for ±20% tolerance. This part is suitable only when circuit design permits wider capacitance variation. ESR is 2 Ohm. Smaller package size (F code) applies.

All three parts maintain ROHS3 compliance, identical operating temperature range, and conformal coating specification. Lead spacing remains constant at 0.098" (2.50 mm), ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can TAP476K006SCS be used in place of TAP476K025SCS in any application?

A: Only if the circuit's maximum operating voltage does not exceed 6.3 V. The substitute part has a lower voltage rating and cannot be used in circuits designed for 25 V operation.

Q: What is the difference between TAP476K006SCS and TAP476M006SCS?

A: Both parts have identical voltage rating (6.3 V), ESR (2 Ohm), and physical dimensions. The difference is tolerance: TAP476K006SCS has ±10% tolerance while TAP476M006SCS has ±20% tolerance. Select based on circuit tolerance requirements.

Q: Will the smaller package size of the substitute parts affect PCB layout?

A: Lead spacing remains constant at 0.098" (2.50 mm) for all three parts, so PCB hole positioning is unchanged. However, the substitute parts use smaller diameter packages (0.236" vs 0.354") and reduced height (0.394" vs 0.512"), which may allow for tighter component placement if needed.

Q: Does the increased ESR of substitute parts affect circuit performance?

A: ESR increases from 1 Ohm to 2 Ohm in the substitute parts. Verify that your circuit design does not require lower impedance. Applications sensitive to ESR (such as high-frequency filtering or low-noise circuits) should retain the main part.

Q: Are all three parts ROHS3 compliant?

A: Yes. TAP476K025SCS, TAP476K006SCS, and TAP476M006SCS are all ROHS3 compliant with identical environmental and regulatory certifications.
