TAP105M020SCS Equivalent & Substitute Parts

Part Overview

The TAP105M020SCS is a 1 µF conformal coated tantalum capacitor rated at 20 V with ±20% tolerance, manufactured by KYOCERA AVX in the TAP series. This through-hole radial component is actively produced and widely used in general-purpose applications requiring reliable energy storage in compact form factors. Substitute parts are identified based on matching capacitance value, compatible voltage ratings, equivalent mechanical dimensions, and identical operating temperature ranges, enabling direct replacement in circuit designs where performance margins allow.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP105M020SCS is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 1 µF (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Lead spacing: 0.098" (2.50 mm) (exact match required)

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 20 V
• Tolerance: ±10% or ±20%
• ESR: 8 Ohm or 10 Ohm
• Physical size: Manufacturer size code A or C (within radial package constraints)

Substitute parts maintain identical electrical function while offering improved voltage margins, tighter tolerance specifications, or reduced ESR characteristics. All substitutes are KYOCERA AVX TAP series components with active product status and equivalent environmental compliance.

Parameter Comparison

Engineering Selection Recommendations

TAP105K050DCS and TAP105K050SCS provide the highest voltage margin at 50 V with improved ±10% tolerance specification and reduced ESR of 8 Ohm. These components are suitable for applications requiring enhanced reliability headroom. Physical dimensions increase to manufacturer size code C (0.197" diameter, 0.335" height maximum), requiring PCB layout verification for space constraints.

TAP105M025SCS offers a moderate voltage upgrade to 25 V while maintaining the compact size code A form factor and 10 Ohm ESR of the original specification. Tolerance remains at ±20%, providing direct functional equivalence with improved voltage safety margin.

TAP105M035SCS delivers 35 V voltage rating with reduced ESR of 8 Ohm while preserving the compact size code A package, balancing performance enhancement with minimal physical footprint change.

All substitute parts maintain active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can TAP105K050DCS or TAP105K050SCS be used as direct drop-in replacements for TAP105M020SCS?

A: Electrical substitution is valid; however, physical layout verification is required. Both parts feature manufacturer size code C with larger dimensions (0.197" diameter, 0.335" height) compared to the original size code A (0.177" diameter, 0.276" height). PCB footprint and component clearance must be confirmed before implementation.

Q: What is the difference between TAP105K050DCS and TAP105K050SCS?

A: Both parts are electrically and mechanically identical with 1 µF capacitance, 50 V rating, ±10% tolerance, and 8 Ohm ESR. Inventory availability differs (1707 pcs vs. 2644 pcs). Selection should be based on supply chain requirements and lead time considerations.

Q: Are TAP105M025SCS and TAP105M035SCS suitable for applications originally designed for TAP105M020SCS?

A: Yes. Both parts maintain identical physical dimensions (size code A), lead spacing, and operating temperature range. TAP105M025SCS provides 25 V rating with matching 10 Ohm ESR, while TAP105M035SCS offers 35 V rating with improved 8 Ohm ESR. Both are direct mechanical and functional substitutes.

Q: What does the tolerance specification mean for substitution purposes?

A: TAP105M020SCS and substitute parts with ±20% tolerance (TAP105M025SCS, TAP105M035SCS) have identical tolerance bands. TAP105K050DCS and TAP105K050SCS feature tighter ±10% tolerance, providing improved capacitance accuracy. Circuit designs tolerating ±20% variation accept both tolerance classes; designs requiring ±10% accuracy must use the K-series parts.

Q: How does ESR affect component selection?

A: ESR (Equivalent Series Resistance) impacts ripple current handling and frequency response. TAP105M020SCS and TAP105M025SCS specify 10 Ohm ESR. TAP105K050DCS, TAP105K050SCS, and TAP105M035SCS specify 8 Ohm ESR, offering improved high-frequency performance. Lower ESR is beneficial in noise-sensitive or high-ripple current applications.

Q: Are all substitute parts ROHS3 compliant and REACH unaffected?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the original TAP105M020SCS component.
