TAP105M020GSB Equivalent & Substitute Parts

Part Overview

The TAP105M020GSB 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 ROHS3 compliant. Substitute parts become necessary when design requirements demand higher voltage ratings, improved tolerance specifications, or when primary inventory is unavailable while maintaining identical capacitance and physical form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP105M020GSB is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance: 1 µF (fixed)
• Package / Case: Radial (fixed)
• Mounting Type: Through Hole (fixed)
• Size / Dimension: 0.177" Dia (4.50mm) (fixed)
• Height - Seated (Max): 0.335" (8.50mm) (fixed)
• Lead Spacing: 0.125" (3.18mm) (fixed)
• Type: Conformal Coated (fixed)
• Operating Temperature Range: -55°C to 125°C (fixed)

Variable Parameters Allowing Substitution:

• Voltage Rating: May be increased from 20 V to 35 V (uprating acceptable)
• Tolerance: May be improved from ±20% to ±10% (tighter tolerance acceptable)
• ESR: May be reduced from 10 Ohm to 8 Ohm (lower ESR acceptable)

The substitute parts TAP105M035GSB and TAP105K035GSB maintain all mandatory parameters while offering higher voltage ratings and improved electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

TAP105M035GSB provides a direct upgrade path with identical tolerance (±20%) while increasing voltage rating to 35 V and reducing ESR to 8 Ohm. This part maintains ROHS3 compliance and Active product status, making it suitable for applications requiring higher voltage headroom within the same tolerance specification.

TAP105K035GSB offers the highest performance specification with ±10% tolerance, 35 V voltage rating, and 8 Ohm ESR. The tighter tolerance and improved ESR characteristics make this part appropriate for precision applications. This part also maintains ROHS3 compliance and Active product status.

Both substitute parts are physically and functionally compatible with the TAP105M020GSB in through-hole PCB applications. Selection between substitutes depends on tolerance and ESR requirements specific to the circuit design.

Frequently Asked Questions (FAQ)

Q: Can TAP105M035GSB or TAP105K035GSB be used as direct replacements for TAP105M020GSB?

A: Yes. Both substitute parts maintain identical physical dimensions (0.177" diameter, 0.335" height, 0.125" lead spacing), capacitance (1 µF), package type (radial), mounting method (through hole), and operating temperature range (-55°C to 125°C). The higher voltage ratings (35 V) are backward compatible with 20 V circuit requirements.

Q: What is the difference between TAP105M035GSB and TAP105K035GSB?

A: Both parts share identical voltage rating (35 V), ESR (8 Ohm), and physical specifications. The primary difference is tolerance: TAP105M035GSB offers ±20% tolerance, while TAP105K035GSB provides ±10% tolerance. Select TAP105K035GSB for applications requiring tighter capacitance accuracy.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts (TAP105M020GSB, TAP105M035GSB, and TAP105K035GSB) are ROHS3 compliant, REACH unaffected, and classified as Active product status. All carry identical ECCN (EAR99) and HTSUS (8532.21.0040) classifications.

Q: Will substituting to a higher voltage rating affect circuit performance?

A: No negative impact is expected. Higher voltage-rated capacitors are suitable for lower voltage applications. The 35 V rated parts will function correctly in circuits designed for 20 V operation.

Q: Are the physical footprints identical for PCB layout purposes?

A: Yes. All three parts share identical dimensions: 0.177" diameter, 0.335" maximum seated height, and 0.125" lead spacing. No PCB layout modifications are required when substituting between these parts.
