Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP336K016SCS is determined by the following criteria:

Primary Electrical Parameters (Must Match):

• Capacitance: 33 µF
• Tolerance: ±10%
• Voltage Rating: 16 V (or higher)
• Type: Conformal Coated
• Operating Temperature: -55°C ~ 125°C

Mechanical Parameters (Must Be Compatible):

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.098" (2.50mm) or 0.100" (2.54mm)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant or equivalent

The substitute parts listed maintain these core parameters while allowing variations in ESR, physical dimensions (diameter and height), and manufacturer size codes, provided the radial package and lead spacing remain compatible with standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Full Equivalents (16 V Rating):

• 199D336X9016D1V1E3 (Vishay Sprague TANTALEX™ 199D series): Maintains 16 V rating, conformal coating, and radial package. ROHS3 compliant. Lead spacing of 0.100" (2.54mm) is compatible with standard 0.1" grid PCB layouts. Suitable for direct substitution where lead spacing tolerance is acceptable.
• T350H336K016AS (KEMET T350 UltraDip II series): Maintains 16 V rating, conformal coating, and radial package. Lead spacing of 0.100" (2.54mm) is compatible with standard 0.1" grid PCB layouts. Note: RoHS non-compliant status may restrict use in applications requiring full RoHS compliance.

Voltage-Reduced Substitute (6.3 V Rating):

• TAP336K006SCS (KYOCERA AVX TAP series): Same manufacturer and series as the main part. Maintains 33 µF capacitance and conformal coating. Voltage rating reduced to 6.3 V. This part is suitable only for applications where the circuit voltage does not exceed 6.3 V. Higher ESR (3 Ohm vs. 1.6 Ohm) may affect circuit performance in noise-sensitive applications.

Compliance Consideration: For applications requiring ROHS3 compliance, select from TAP336K016SCS, TAP336K006SCS, or 199D336X9016D1V1E3. The T350H336K016AS is RoHS non-compliant and should not be used in regulated environments.

Frequently Asked Questions (FAQ)

Q: Can TAP336K006SCS be used as a direct replacement for TAP336K016SCS?

A: No. The TAP336K006SCS has a reduced voltage rating of 6.3 V compared to the 16 V rating of the TAP336K016SCS. Use this substitute only in circuits where the maximum operating voltage does not exceed 6.3 V. Using a lower-rated capacitor in a higher-voltage circuit will result in component failure.

Q: What is the difference in lead spacing between the main part and substitute parts?

A: The TAP336K016SCS and TAP336K006SCS have lead spacing of 0.098" (2.50mm). The 199D336X9016D1V1E3 and T350H336K016AS have lead spacing of 0.100" (2.54mm). Both spacings are compatible with standard through-hole PCB layouts, though the 0.100" spacing aligns with the industry-standard 0.1" grid. Verify PCB hole spacing before selection.

Q: Are all substitute parts ROHS3 compliant?

A: No. The TAP336K016SCS, TAP336K006SCS, and 199D336X9016D1V1E3 are ROHS3 compliant. The T350H336K016AS is RoHS non-compliant. For applications requiring ROHS3 compliance, do not use the T350H336K016AS.

Q: What does ESR mean and why does it vary between parts?

A: ESR (Equivalent Series Resistance) represents the internal resistance of the capacitor. The TAP336K016SCS and T350H336K016AS both have 1.6 Ohm ESR, while the TAP336K006SCS has 3 Ohm ESR. Higher ESR increases heat generation and may affect circuit performance in high-frequency or noise-sensitive applications. Select parts with matching ESR when circuit performance is critical.

Q: Can I use 199D336X9016D1V1E3 or T350H336K016AS as direct replacements for TAP336K016SCS?

A: Both parts maintain the 33 µF capacitance, 16 V rating, conformal coating, and radial through-hole package. Physical dimensions vary slightly (diameter and height), so verify that the PCB layout accommodates the larger case size. Lead spacing differences (0.100" vs. 0.098") are compatible with standard PCB grids. For ROHS3-compliant applications, use 199D336X9016D1V1E3. The T350H336K016AS is suitable only for non-regulated applications.
