TAP105K020GSB Equivalent & Substitute Parts

Part Overview

The TAP105K020GSB is a 1 µF conformal coated tantalum capacitor rated for 20 V operation in a radial through-hole package. Manufactured by KYOCERA AVX, this component is classified as Active product status and is suitable for general-purpose applications requiring reliable energy storage in compact form factors. Substitute parts may be required due to inventory constraints, design upgrades for higher voltage margins, or application-specific performance requirements such as reduced equivalent series resistance.

Substitute Part Grouping Explanation

Substitution for the TAP105K020GSB is determined by strict equivalence in the following parameters:

• Capacitance Value: Must remain 1 µF (no tolerance deviation acceptable for direct substitution)
• Tolerance: Must maintain ±10%
• Type: Must be Conformal Coated tantalum capacitor
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial
• Physical Dimensions: Must match 0.177" Dia (4.50 mm) and 0.335" (8.50 mm) height
• Lead Spacing: Must match 0.125" (3.18 mm)
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance: Must maintain ROHS3 compliance

The TAP105K035GSB qualifies as a substitute based on identical capacitance, tolerance, type, mounting, package, dimensions, lead spacing, temperature range, and compliance status. The voltage rating increase from 20 V to 35 V represents an upgrade path, and the ESR reduction from 10 Ohm to 8 Ohm provides improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TAP105K035GSB is a direct substitute for the TAP105K020GSB in applications where the circuit design permits operation at the higher 35 V rating. Both components maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The substitute part offers improved electrical performance through reduced ESR (8 Ohm versus 10 Ohm) while maintaining all mechanical and thermal specifications. Selection between these parts depends solely on the maximum voltage requirement of the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can TAP105K035GSB replace TAP105K020GSB in any circuit?

A: The TAP105K035GSB is electrically and mechanically compatible with TAP105K020GSB provided the circuit design operates at or below 35 V. The higher voltage rating of the substitute does not create incompatibility; however, circuit voltage specifications must be verified before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical radial package dimensions: 0.177" diameter (4.50 mm), 0.335" maximum seated height (8.50 mm), and 0.125" lead spacing (3.18 mm). Direct board-level substitution is mechanically feasible without layout modifications.

Q: What is the significance of the ESR difference?

A: The TAP105K035GSB exhibits lower equivalent series resistance (8 Ohm) compared to the TAP105K020GSB (10 Ohm). This parameter affects ripple current handling and thermal performance. Applications sensitive to ESR characteristics should evaluate this difference against specific performance requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP105K020GSB and TAP105K035GSB are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Compliance documentation is equivalent between the two parts.

Q: Is conformal coating present on both substitute options?

A: Yes. Both the main part and substitute are conformal coated tantalum capacitors, providing identical environmental protection characteristics.
