TAP476M025SCS Equivalent & Substitute Parts

Part Overview

The TAP476M025SCS is a 47 µF conformal coated tantalum capacitor rated at 25 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is part of the active TAP series and is ROHS3 compliant. Alternative models may be required due to application voltage requirements, inventory constraints, or specific ESR specifications for circuit performance optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAP476M025SCS is determined by the following critical parameters:

• Capacitance Value: Must remain 47 µF
• Tolerance: Must be ±20%
• Type: Must be Conformal Coated
• Mounting Type: Must be Through Hole Radial
• Lead Spacing: Must be 0.098" (2.50mm)
• Operating Temperature Range: Must support -55°C ~ 125°C
• Compliance: Must maintain ROHS3 compliance

The substitute part TAP476M006SCS shares identical capacitance, tolerance, type, mounting configuration, and lead spacing. The primary difference is the rated voltage specification (6.3 V versus 25 V), which determines applicability based on circuit voltage requirements. Both parts are manufactured by KYOCERA AVX within the active TAP series.

Parameter Comparison

Engineering Selection Recommendations

The TAP476M006SCS is a valid substitute for the TAP476M025SCS when circuit voltage requirements do not exceed 6.3 V. Both components maintain active product status and ROHS3 compliance. The TAP476M006SCS exhibits a smaller physical footprint (0.236" diameter versus 0.354" diameter) and higher ESR (2 Ohm versus 1 Ohm). Selection between these parts must be based on the maximum voltage present in the application circuit. The TAP476M025SCS is required for applications operating at voltages between 6.3 V and 25 V.

Frequently Asked Questions (FAQ)

Q: Can TAP476M006SCS replace TAP476M025SCS in any application?

A: No. The TAP476M006SCS is rated for 6.3 V maximum. It can only be used in applications where the circuit voltage does not exceed 6.3 V. Using a lower-voltage rated capacitor in a higher-voltage circuit will result in component failure.

Q: What are the physical differences between these parts?

A: The TAP476M006SCS has a smaller diameter (0.236" versus 0.354") and lower height (0.394" versus 0.512"). Lead spacing remains identical at 0.098" (2.50mm), maintaining PCB compatibility for through-hole mounting.

Q: How does ESR affect substitution?

A: The TAP476M006SCS has an ESR of 2 Ohm compared to 1 Ohm for the TAP476M025SCS. ESR impacts ripple current handling and heat dissipation. Applications with strict ESR requirements must use the part specified in the design.

Q: Are both parts RoHS compliant?

A: Yes. Both TAP476M025SCS and TAP476M006SCS are ROHS3 compliant and REACH unaffected.

Q: What is the primary substitution criterion?

A: Voltage rating is the primary criterion. The TAP476M006SCS can only substitute the TAP476M025SCS in circuits operating at 6.3 V or below. All other electrical and mechanical parameters must match the application requirements.
