TAP226K035SCS Equivalent & Substitute Parts

Part Overview

The TAP226K035SCS is a 22 µF conformal coated tantalum capacitor rated at 35 V with ±10% tolerance, manufactured by KYOCERA AVX in the TAP series. This radial through-hole component features 1.3Ohm equivalent series resistance and operates across -55°C to 125°C. The part is currently active in production with 2260 units in stock.

Substitute parts are identified when design requirements allow for relaxed voltage ratings, increased tolerance specifications, or alternative manufacturer sourcing while maintaining core electrical functionality and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP226K035SCS is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value must remain 22 µF
• Voltage rating must be equal to or greater than 35 V
• Tolerance must be ±10% or tighter
• ESR must not exceed 1.3Ohm
• Mounting type must be through-hole radial
• Operating temperature range must encompass -55°C ~ 125°C
• Type must be conformal coated tantalum

Substitution Groups:

Group 1 - Voltage Derating Substitutes: Parts with reduced voltage ratings (10 V) are not direct substitutes for 35 V applications. These parts are listed as available alternatives only when circuit design permits voltage derating and do not meet the primary substitution criteria for standard 35 V applications.

Group 2 - Exact Electrical Match, Different Manufacturer: The T350K226K035AS from KEMET matches all electrical specifications (22 µF, 35 V, ±10%, 1.3Ohm ESR) and represents a true cross-manufacturer equivalent. Physical dimensions differ slightly due to manufacturer design standards.

Parameter Comparison

Engineering Selection Recommendations

T350K226K035AS (KEMET) is the only true electrical equivalent meeting all primary substitution criteria. This part maintains 22 µF capacitance, 35 V rating, ±10% tolerance, and 1.3Ohm ESR. However, the RoHS non-compliant status must be evaluated against project compliance requirements. Physical dimensions differ (0.350" vs 0.335" diameter, 0.200" vs 0.098" lead spacing), requiring PCB layout verification before implementation.

TAP226K010SCS and TAP226M010SCS do not meet substitution criteria for 35 V applications due to reduced voltage ratings (10 V) and increased ESR (2.7Ohm). These parts are available only for applications where circuit design permits voltage derating below 10 V. TAP226M010SCS additionally carries ±20% tolerance, further limiting compatibility.

For applications requiring ROHS3 compliance and exact electrical specifications, TAP226K035SCS remains the primary selection. The T350K226K035AS serves as an alternative only when RoHS non-compliance is acceptable and PCB layout accommodates the different lead spacing.

Frequently Asked Questions (FAQ)

Q: Can TAP226K010SCS replace TAP226K035SCS in a 35 V circuit?

A: No. The TAP226K010SCS is rated for 10 V maximum. Using a 10 V component in a 35 V circuit exceeds the component's voltage rating and creates reliability and safety risks. Substitution is only valid when circuit voltage requirements are 10 V or lower.

Q: What is the difference between TAP226K010SCS and TAP226M010SCS?

A: Both parts share identical electrical ratings (22 µF, 10 V, 2.7Ohm ESR) and physical dimensions. The primary difference is tolerance: TAP226K010SCS carries ±10% tolerance while TAP226M010SCS carries ±20% tolerance. Selection depends on circuit tolerance requirements.

Q: Is T350K226K035AS a direct replacement for TAP226K035SCS?

A: T350K226K035AS matches all electrical specifications (22 µF, 35 V, ±10%, 1.3Ohm ESR) but differs in physical dimensions and lead spacing (0.200" vs 0.098"). PCB layout must be verified for compatibility. Additionally, T350K226K035AS is RoHS non-compliant, which may conflict with project requirements.

Q: Why do the 10 V parts have higher ESR than the 35 V parts?

A: ESR is determined by the component's internal construction and voltage rating. The 10 V rated parts (TAP226K010SCS, TAP226M010SCS) exhibit 2.7Ohm ESR, while the 35 V rated parts (TAP226K035SCS, T350K226K035AS) exhibit 1.3Ohm ESR. This is a characteristic of the respective product lines and does not indicate deficiency.

Q: Can I use T350K226K035AS if my design requires ROHS3 compliance?

A: No. T350K226K035AS is RoHS non-compliant. For ROHS3 compliant applications, TAP226K035SCS is the required selection.

Q: What lead spacing considerations apply to T350K226K035AS?

A: T350K226K035AS uses 0.200" (5.08mm) lead spacing compared to 0.098" (2.50mm) for TAP226K035SCS. PCB footprints are not interchangeable. Layout redesign is required if substitution is pursued.
