TAP336K025SCS Equivalent & Substitute Parts

Part Overview

The TAP336K025SCS is a 33 µF conformal coated tantalum capacitor rated at 25 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is part of the active TAP series and is ROHS3 compliant. Finding equivalent or substitute parts may be necessary due to inventory constraints, application-specific requirements, or design optimization needs where voltage or ESR specifications differ from the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of tantalum capacitors is determined by the following critical parameters:

• Capacitance Value: Must match exactly at 33 µF
• Tolerance: Must be ±10% or tighter
• Voltage Rating: Substitute must meet or exceed the application voltage requirement
• Type & Coating: Must be conformal coated for environmental protection
• Mounting Configuration: Must be radial through-hole
• Temperature Range: Must support -55°C ~ 125°C operation
• Compliance: Must maintain ROHS3 and REACH compliance status

The TAP336K006SCS is listed as a manufacturer-recommended substitute. This part shares identical capacitance, tolerance, temperature range, mounting type, and compliance certifications. The primary difference is the reduced voltage rating (6.3 V versus 25 V), which makes this substitute suitable only for applications where the circuit voltage does not exceed 6.3 V.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP336K025SCS and TAP336K006SCS maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts depends on circuit voltage requirements:

• TAP336K025SCS: Use when circuit voltage reaches or approaches 25 V. This part provides lower ESR (1.2 Ohm) and larger physical dimensions suitable for higher voltage applications.

• TAP336K006SCS: Use only when circuit voltage does not exceed 6.3 V. This substitute offers a smaller footprint (0.217" diameter versus 0.315" diameter) and reduced height, beneficial for space-constrained designs. The higher ESR (3 Ohm) is acceptable in low-voltage applications where ripple current and thermal dissipation are not critical factors.

Both parts are manufactured by KYOCERA AVX and share identical lead spacing (0.098"), enabling direct PCB footprint compatibility when voltage requirements permit substitution.

Frequently Asked Questions (FAQ)

Q: Can TAP336K006SCS replace TAP336K025SCS in any application?

A: No. The TAP336K006SCS has a maximum voltage rating of 6.3 V. It can only replace the TAP336K025SCS in circuits where the 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 physical footprint difference between these parts?

A: The TAP336K025SCS has a diameter of 0.315" (8.00mm) and height of 0.453" (11.50mm). The TAP336K006SCS has a smaller diameter of 0.217" (5.50mm) and height of 0.354" (9.00mm). Both share the same 0.098" (2.50mm) lead spacing, allowing PCB footprint compatibility when voltage requirements permit.

Q: How does ESR differ between these parts?

A: The TAP336K025SCS has an ESR of 1.2 Ohm, while the TAP336K006SCS has an ESR of 3 Ohm. Higher ESR increases heat dissipation and ripple current sensitivity. The TAP336K006SCS is suitable for low-voltage, low-ripple-current applications where the higher ESR does not impact circuit performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TAP336K025SCS and TAP336K006SCS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the lead spacing for both parts?

A: Both parts have identical lead spacing of 0.098" (2.50mm), ensuring compatibility with the same PCB hole pattern when voltage requirements permit substitution.
