Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP335K035SCS is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 3.3 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 35 V (exact match or higher required)
• Type: Conformal Coated (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match or wider range acceptable)
• Lifetime @ Temp.: 1000 Hrs @ 85°C (exact match or longer acceptable)
• RoHS Status: ROHS3 Compliant (exact match required)

Secondary Compatibility Factors:

• Physical dimensions (diameter, height, lead spacing) must accommodate PCB layout constraints
• ESR characteristics must be compatible with circuit performance requirements
• Manufacturer series designation does not restrict substitution if primary criteria are met

Two substitute parts meet these criteria: TAP335K010SCS (same manufacturer, lower voltage rating) and 199D335X9035B1V1E3 (alternative manufacturer, equivalent voltage rating).

Parameter Comparison

Engineering Selection Recommendations

TAP335K010SCS (KYOCERA AVX): This substitute is suitable only for applications where the circuit operates at 10 V or lower. The reduced voltage rating of 10 V makes this part incompatible with designs requiring 35 V operation. Physical dimensions are smaller (0.177" diameter, 0.276" height), which may provide space advantages but requires PCB layout verification. ESR is higher at 10 Ohm compared to the main part's 4 Ohm specification. All compliance certifications (ROHS3, REACH Unaffected, EAR99) match the original specification. This part is recommended only when circuit voltage requirements are confirmed at 10 V or below.

199D335X9035B1V1E3 (Vishay Sprague TANTALEX™ Series): This substitute maintains the 35 V voltage rating and 3.3 µF capacitance of the original part, making it electrically equivalent for applications requiring full 35 V operation. Physical dimensions are nearly identical to the main part (0.197" diameter, 0.300" height), with lead spacing at 0.100" (2.54mm) versus the original 0.098" (2.50mm). ESR is not specified in available documentation. All compliance certifications (ROHS3, REACH Unaffected, EAR99) align with the original specification. This part is recommended as a direct functional equivalent when KYOCERA AVX TAP335K035SCS availability is constrained.

Both substitute parts maintain Active product status and identical operating temperature ranges (-55°C ~ 125°C) and lifetime specifications (1000 Hrs @ 85°C).

Frequently Asked Questions (FAQ)

Q: Can TAP335K010SCS be used as a direct replacement for TAP335K035SCS?

A: TAP335K010SCS is not a direct replacement. While both parts share identical capacitance (3.3 µF), tolerance (±10%), and mounting characteristics, the voltage rating differs significantly. TAP335K010SCS is rated at 10 V, whereas TAP335K035SCS is rated at 35 V. Use TAP335K010SCS only in circuits designed for 10 V operation. Using a lower-voltage-rated capacitor in a higher-voltage application creates reliability and safety risks.

Q: Is 199D335X9035B1V1E3 a suitable equivalent for TAP335K035SCS?

A: Yes, 199D335X9035B1V1E3 is a suitable functional equivalent. Both parts share the same capacitance (3.3 µF), tolerance (±10%), voltage rating (35 V), conformal coating type, and radial through-hole mounting. Physical dimensions are nearly identical, with minor variations in height (0.300" versus 0.335") and lead spacing (0.100" versus 0.098"). Verify PCB layout compatibility before substitution.

Q: What are the key differences in physical dimensions between these parts?

A: TAP335K035SCS has a diameter of 0.197" (5.00mm), height of 0.335" (8.50mm), and lead spacing of 0.098" (2.50mm). TAP335K010SCS is smaller with 0.177" (4.50mm) diameter and 0.276" (7.00mm) height. 199D335X9035B1V1E3 matches the main part's diameter at 0.197" (5.00mm) but has a slightly reduced height of 0.300" (7.62mm) and lead spacing of 0.100" (2.54mm). Confirm PCB footprint compatibility before selecting a substitute.

Q: Do all three parts meet the same compliance requirements?

A: Yes. TAP335K035SCS, TAP335K010SCS, and 199D335X9035B1V1E3 are all ROHS3 Compliant, REACH Unaffected, and classified as EAR99 under export control regulations. All three parts maintain identical operating temperature ranges (-55°C ~ 125°C) and lifetime specifications (1000 Hrs @ 85°C).

Q: What is the significance of ESR differences between these parts?

A: ESR (Equivalent Series Resistance) affects circuit performance in high-frequency applications and power delivery circuits. TAP335K035SCS has 4 Ohm ESR, TAP335K010SCS has 10 Ohm ESR, and 199D335X9035B1V1E3 has unspecified ESR. Higher ESR increases impedance and heat generation. For applications sensitive to ESR characteristics, verify that the substitute part's ESR specification meets circuit requirements before substitution.

Q: Can these parts be used interchangeably in all applications?

A: No. Substitution is application-dependent. TAP335K010SCS is restricted to 10 V or lower circuits. 199D335X9035B1V1E3 is suitable for 35 V applications but requires PCB layout verification due to minor dimensional variations. Always confirm voltage requirements, physical space constraints, and ESR specifications before substituting any component.
