Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP335M025SPA is determined by the following critical parameters:

• Capacitance Value: Must be 3.3 µF (no deviation permitted)
• Voltage Rating: Must be 25 V or higher
• Package Type: Must be radial through-hole configuration
• Physical Dimensions: Must match 0.177" diameter (4.50 mm) and 0.295" maximum height (7.50 mm)
• Conformal Coating: Must be present for environmental protection equivalence
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance: Must maintain ROHS3 compliance

The TAP335K025SCS qualifies as a direct substitute based on these parameters. The primary distinction is tolerance specification: the substitute offers ±10% tolerance compared to the original ±20% tolerance, representing an upgrade in capacitance accuracy while maintaining all other electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both TAP335M025SPA and TAP335K025SCS are active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on tolerance requirements:

• TAP335M025SPA is appropriate for applications where ±20% capacitance tolerance is acceptable and cost optimization is prioritized.
• TAP335K025SCS is suitable for designs requiring tighter capacitance accuracy at ±10% tolerance. This substitute provides improved performance margin in circuits sensitive to capacitance variation.

Both parts are physically and electrically interchangeable within the specified parameter boundaries. The conformal coating on both variants ensures equivalent environmental protection for harsh operating conditions.

Frequently Asked Questions (FAQ)

Q: Can TAP335K025SCS replace TAP335M025SPA in existing designs?

A: Yes. The TAP335K025SCS is a direct substitute with identical physical dimensions, voltage rating, capacitance value, and operating temperature range. The tighter ±10% tolerance represents an upgrade in performance characteristics.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance defines the acceptable deviation from the nominal 3.3 µF capacitance value. TAP335M025SPA allows ±20% deviation (2.64 µF to 3.96 µF), while TAP335K025SCS allows ±10% deviation (2.97 µF to 3.63 µF). Applications with strict capacitance requirements benefit from the tighter tolerance of the substitute.

Q: Are the physical packages identical?

A: Yes. Both parts use identical radial through-hole packages with 0.177" diameter (4.50 mm), 0.295" maximum seated height (7.50 mm), and 0.098" lead spacing (2.50 mm). PCB layout and mechanical mounting are fully compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP335M025SPA and TAP335K025SCS are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: What is the ESR specification and does it differ between these parts?

A: Equivalent Series Resistance (ESR) is 5 Ohm for both parts. ESR affects high-frequency performance and ripple current handling. The identical ESR specification ensures equivalent electrical behavior in AC applications.
