TAP226M035FCS Equivalent & Substitute Parts

Part Overview

The TAP226M035FCS is a 22 µF conformal coated tantalum capacitor rated for 35 V with ±20% tolerance, manufactured by KYOCERA AVX in the TAP series. This through-hole radial component is designed for general-purpose applications requiring reliable energy storage in compact form factors. The part is currently active in production with 1026 units in stock. Substitute parts are identified when design requirements allow for tolerance upgrades, voltage rating increases, or when inventory constraints necessitate alternative sourcing from the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP226M035FCS is determined by the following criteria:

Capacitance: All substitutes maintain 22 µF to ensure functional equivalence in energy storage capacity.

Voltage Rating: Substitutes with equal or higher voltage ratings (35 V or 50 V) are acceptable, as higher ratings provide design margin without affecting circuit performance at the original operating voltage.

Tolerance: Substitutes with ±10% tolerance represent an upgrade from the original ±20% specification, providing tighter capacitance control. Parts with ±20% tolerance remain equivalent.

Type & Coating: All substitutes maintain conformal coating and tantalum construction for environmental protection and reliability.

Mounting & Package: All substitutes use through-hole radial mounting with compatible lead spacing (0.197" / 5.00 mm) and operating temperature range (-55°C to 125°C).

Compliance: All substitutes maintain ROHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

TAP226K035CCS is a direct upgrade substitute when tolerance improvement is required. It maintains identical voltage rating and physical dimensions while providing ±10% tolerance instead of ±20%. Both parts use the same size code K and are ROHS3 compliant with equivalent ESR characteristics.

TAP226K050CCS and TAP226M050CCS are suitable when circuit design permits higher voltage ratings. The 50 V rating provides additional design margin for 35 V applications. These parts use size code L with slightly larger diameter (0.354" vs 0.335") but maintain the same height and lead spacing. ESR is reduced to 1 Ohm, improving transient response. Both maintain ROHS3 compliance and the full operating temperature range.

Selection between ±10% and ±20% tolerance variants depends on circuit requirements for capacitance accuracy. Selection between 35 V and 50 V ratings depends on available board space and voltage margin requirements.

Frequently Asked Questions (FAQ)

Q: Can TAP226K035CCS replace TAP226M035FCS in any application? A: Yes. TAP226K035CCS is a direct substitute with identical voltage rating, physical dimensions, and mounting configuration. The ±10% tolerance is tighter than the original ±20%, making it suitable for all applications requiring the original part.

Q: What is the physical difference between 35 V and 50 V variants? A: The 50 V variants (TAP226K050CCS and TAP226M050CCS) have a larger diameter of 0.354" (9.00 mm) compared to 0.335" (8.50 mm) for 35 V parts. Height remains 0.551" (14.00 mm) for all variants. Lead spacing is identical at 0.197" (5.00 mm).

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original TAP226M035FCS certification.

Q: What is the difference between tolerance grades K and M? A: Tolerance grade K specifies ±10% capacitance variation, while grade M specifies ±20%. Grade K provides tighter control over actual capacitance values and is suitable for applications requiring higher accuracy.

Q: Can 50 V rated parts be used in 35 V circuits? A: Yes. Higher voltage-rated capacitors operate safely at lower voltages. The 50 V rating provides additional design margin and is electrically compatible with 35 V circuit requirements.

Q: How does ESR affect part selection? A: ESR (Equivalent Series Resistance) affects transient response and ripple current handling. The 35 V variants have 1.3 Ohm ESR, while 50 V variants have 1 Ohm ESR. Lower ESR improves performance in high-frequency or high-ripple applications.
