Substitute Part Grouping Explanation

Substitution eligibility for the TAP476M010SPA is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Capacitance: 47 µF (exact match required)
• Voltage Rating: 10 V (minimum, equal or higher acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical Dimensions: 0.256" Dia (6.50mm), Height 0.394" (10.00mm), Lead Spacing 0.098" (2.50mm) (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 1.7 Ohm (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% or tighter (±10% acceptable as upgrade)

The substitute part TAP476K010SCS meets all mandatory equivalence criteria with an improved tolerance specification of ±10%, providing enhanced capacitance accuracy while maintaining identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both TAP476M010SPA and TAP476K010SCS are active production components from KYOCERA AVX with identical ROHS3 compliance and regulatory status. Selection between these parts is based on tolerance requirements:

TAP476M010SPA is suitable for applications where ±20% capacitance tolerance is acceptable and cost optimization is prioritized.

TAP476K010SCS is suitable for applications requiring tighter capacitance accuracy with ±10% tolerance. This substitute provides enhanced performance characteristics while maintaining identical electrical and mechanical specifications, physical footprint compatibility, and regulatory compliance.

Both parts are manufactured by the same supplier, utilize identical conformal coating, and operate within the same temperature range with equivalent ESR characteristics. Selection should be based on circuit design tolerance requirements and application specifications.

Frequently Asked Questions (FAQ)

Q: Can TAP476K010SCS be used as a direct replacement for TAP476M010SPA?

A: Yes. TAP476K010SCS is a direct substitute with identical electrical performance, physical dimensions, and mechanical compatibility. The only difference is improved tolerance specification (±10% versus ±20%).

Q: What does the tolerance difference mean for circuit performance?

A: Tolerance specifies the allowable deviation from the nominal 47 µF capacitance value. TAP476M010SPA allows deviation between 37.6 µF and 56.4 µF. TAP476K010SCS allows deviation between 42.3 µF and 51.7 µF. Applications requiring tighter capacitance accuracy should use the ±10% tolerance part.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical radial package dimensions: 0.256" diameter (6.50mm), 0.394" maximum seated height (10.00mm), and 0.098" lead spacing (2.50mm). PCB layout and mechanical clearance requirements are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both TAP476M010SPA and TAP476K010SCS are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications.

Q: What is the ESR significance for these parts?

A: Both parts have 1.7 Ohm equivalent series resistance. ESR affects ripple current handling and frequency response. Identical ESR values ensure equivalent performance in filtering and energy storage applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design tolerance requirements are met. If the original design specified TAP476M010SPA with ±20% tolerance, TAP476K010SCS with ±10% tolerance will function identically or with improved performance. If the design requires exactly ±20% tolerance for specific reasons, verify compatibility before substitution.
