TAP475M010SLZ Equivalent & Substitute Parts

Part Overview

The TAP475M010SLZ is a 4.7 µF conformal coated tantalum capacitor rated at 10 V with ±20% 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 970 units in stock. Substitute parts are identified when design requirements allow for improved tolerance specifications or higher voltage ratings while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP475M010SLZ is determined by the following criteria:

Primary Substitution Criteria (Must Match):

• Capacitance value: 4.7 µF (exact match required)
• Conformal coated tantalum type
• Through-hole radial mounting configuration
• Operating temperature range: -55°C to 125°C
• Lifetime specification: 1000 Hrs @ 85°C
• RoHS3 compliance and REACH unaffected status

Allowable Variations:

• Tolerance: May be tighter (±10% acceptable as upgrade)
• Voltage rating: May be equal or higher (10 V or greater acceptable)
• ESR: May be lower (improved performance)
• Physical dimensions: Constrained by lead spacing (0.098" fixed) and mounting compatibility
• Packaging format: Bulk or Cut Tape acceptable

The two identified substitutes meet these criteria with specific enhancements detailed in the comparison table below.

Engineering Selection Recommendations

TAP475K010SCS Selection Criteria: This substitute provides identical electrical and mechanical specifications to the main part with the exception of improved tolerance (±10% versus ±20%). Selection is appropriate when tighter capacitance tolerance is required without changing voltage or physical footprint. All compliance certifications (ROHS3, REACH unaffected) remain equivalent. Higher inventory availability (3100 units) supports supply chain continuity.

TAP475K025SRW Selection Criteria: This substitute maintains the 4.7 µF capacitance and ±10% tolerance while providing a higher voltage rating (25 V versus 10 V) and lower ESR (4 Ohm versus 8 Ohm). Physical dimensions increase slightly (0.197" diameter, 0.335" height versus 0.177" diameter, 0.276" height). Selection is appropriate for applications requiring voltage derating margin or reduced impedance characteristics. Lead spacing remains compatible at 0.098" (2.50mm). All compliance certifications remain equivalent.

Both substitutes maintain active product status and full regulatory compliance with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TAP475K010SCS be used as a direct replacement for TAP475M010SLZ? A: Yes. TAP475K010SCS is electrically and mechanically compatible with identical voltage rating, capacitance, and physical dimensions. The primary difference is improved tolerance specification (±10% versus ±20%), which represents an upgrade in performance without requiring circuit redesign.

Q: What are the physical space implications of using TAP475K025SRW? A: TAP475K025SRW has a larger footprint. Diameter increases from 0.177" (4.50mm) to 0.197" (5.00mm), and seated height increases from 0.276" (7.00mm) to 0.335" (8.50mm). Lead spacing remains constant at 0.098" (2.50mm), so PCB hole patterns are compatible. Verify available board space before selection.

Q: Are there packaging format differences between these parts? A: TAP475M010SLZ and TAP475K010SCS are supplied in Bulk packaging. TAP475K025SRW is supplied in Cut Tape (CT) format. Both formats are suitable for through-hole assembly; packaging selection depends on production volume and handling requirements.

Q: Do all three parts meet the same compliance requirements? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.21.0040) classifications. Regulatory requirements do not differentiate between these substitutes.

Q: What is the significance of the ESR difference between TAP475M010SLZ and TAP475K025SRW? A: TAP475K025SRW has lower ESR (4 Ohm versus 8 Ohm), which reduces impedance and heat generation in high-frequency or high-current applications. This is a performance improvement but is not required for basic capacitance functionality. Selection depends on circuit requirements for ripple current handling and thermal management.

Q: Can TAP475K025SRW be used in a 10 V circuit? A: Yes. TAP475K025SRW is rated for 25 V, which exceeds the 10 V requirement. Higher voltage rating provides derating margin and does not negatively affect circuit operation at lower voltages. Verify that the increased physical dimensions fit the available PCB space.
