Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP336K020SCS is determined by the following criteria:

Allowed Substitution Parameters:

• Capacitance value must remain 33 µF
• Tolerance must remain ±10%
• Mounting type must remain Through Hole
• Package type must remain Radial
• Type must remain Conformal Coated
• Operating temperature range must remain -55°C ~ 125°C
• RoHS and REACH compliance status must be maintained

Variable Parameters (Substitution Basis):

• Voltage rating may increase (higher voltage rating provides backward compatibility)
• ESR may vary within acceptable limits for the application
• Physical dimensions may differ based on voltage rating
• Manufacturer size code may change

Two substitute parts are identified within the TAP series:

TAP336K025SCS - Upgrade substitute with increased voltage rating (25 V) and improved ESR (1.2 Ohm), maintaining identical physical footprint and all core specifications.

TAP336K006SCS - Downgrade substitute with reduced voltage rating (6.3 V) and higher ESR (3 Ohm), with reduced physical dimensions due to lower voltage classification.

Parameter Comparison

Engineering Selection Recommendations

TAP336K025SCS Selection Criteria: The TAP336K025SCS is suitable for direct substitution in applications where the circuit voltage rating permits. This part provides improved ESR performance (1.2 Ohm versus 1.4 Ohm) and maintains identical physical dimensions and lead spacing. Both parts share ROHS3 compliance and REACH unaffected status. The increased voltage rating (25 V) provides design margin for circuits originally specified at 20 V.

TAP336K006SCS Selection Criteria: The TAP336K006SCS is applicable only in circuits where the maximum operating voltage does not exceed 6.3 V. This part features reduced physical dimensions (0.217" diameter, 0.354" height) compared to the main part. The higher ESR rating (3 Ohm) must be evaluated against circuit performance requirements. ROHS3 compliance and REACH unaffected status are maintained. PCB layout modifications may be required due to dimensional differences.

Compliance Considerations: All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across substitution options.

Frequently Asked Questions (FAQ)

Q: Can TAP336K025SCS replace TAP336K020SCS in any application? A: TAP336K025SCS can replace TAP336K020SCS in applications where the circuit is designed for 20 V operation or lower. The higher voltage rating (25 V) provides additional design margin. Physical dimensions and lead spacing are identical, requiring no PCB layout changes.

Q: What are the limitations of using TAP336K006SCS as a substitute? A: TAP336K006SCS is limited to circuits with maximum operating voltages of 6.3 V or lower. The part exhibits higher ESR (3 Ohm) and reduced physical dimensions. PCB layout modifications may be necessary due to the smaller case size (0.217" diameter versus 0.315" diameter).

Q: Are all substitute parts ROHS3 compliant? A: Yes. TAP336K020SCS, TAP336K025SCS, and TAP336K006SCS are all ROHS3 compliant and REACH unaffected.

Q: Do the substitute parts have identical lead spacing? A: Yes. All three parts maintain 0.098" (2.50mm) lead spacing, ensuring compatibility with existing PCB footprints for TAP336K025SCS. TAP336K006SCS has identical lead spacing but different overall dimensions.

Q: What is the impact of ESR differences between substitute parts? A: TAP336K025SCS has lower ESR (1.2 Ohm) compared to the main part (1.4 Ohm), providing improved performance. TAP336K006SCS has higher ESR (3 Ohm), which may affect ripple current handling and thermal performance in high-frequency applications.

Q: Are there inventory considerations for these substitutes? A: TAP336K025SCS has higher inventory availability (2200 Pcs) compared to TAP336K020SCS (1126 Pcs). TAP336K006SCS inventory is 1439 Pcs. All parts are listed as New Original In Stock.
