TAP225K035SCS Equivalent & Substitute Parts

Part Overview

The TAP225K035SCS is a 2.2 µF conformal coated tantalum capacitor rated for 35 V operation in a radial through-hole package. Manufactured by KYOCERA AVX, this component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance performance across the operating temperature range of -55°C to 125°C. Substitute parts may be required due to inventory availability, supply chain constraints, or specific design requirements that allow for alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP225K035SCS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage - Rated: 35 V (exact match required)
• Type: Conformal Coated (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)

Allowable Variations:

• ESR (Equivalent Series Resistance): May vary within manufacturer specifications
• Physical dimensions: Minor variations permitted within industry standards for radial packages
• Manufacturer Size Code: May differ between manufacturers
• Lifetime @ Temp.: Specification may vary or be unspecified

Substitute parts must match all critical parameters to ensure functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (35 V Rated):

199D225X9035B1V1E3 (Vishay Sprague TANTALEX™ 199D series) and T350C225K035AS (KEMET T350 UltraDip II series) are direct electrical equivalents to the TAP225K035SCS. Both parts match all critical electrical parameters: 2.2 µF capacitance, ±10% tolerance, 35 V rating, conformal coating, through-hole radial package, and -55°C to 125°C operating temperature range. Selection between these three parts may be based on inventory availability, lead time, or compliance requirements. The TAP225K035SCS and 199D225X9035B1V1E3 maintain ROHS3 compliance, while T350C225K035AS is RoHS non-compliant.

Non-Equivalent Substitute:

TAP225K010SCS is not a functional equivalent. Although it shares the same manufacturer (KYOCERA AVX), capacitance value (2.2 µF), tolerance (±10%), and package type (radial through-hole), it is rated for 10 V operation, not 35 V. This part cannot be substituted in circuits requiring 35 V rated capacitors.

Frequently Asked Questions (FAQ)

Q: Can TAP225K010SCS replace TAP225K035SCS?

A: No. TAP225K010SCS is rated for 10 V maximum, while TAP225K035SCS is rated for 35 V. Using a lower voltage-rated capacitor in a 35 V circuit creates risk of component failure and circuit malfunction.

Q: What are the physical differences between substitute parts?

A: All substitute parts are radial through-hole packages with similar form factors. TAP225K035SCS has a maximum seated height of 0.295" (7.50mm) with 0.098" (2.50mm) lead spacing. 199D225X9035B1V1E3 has a maximum seated height of 0.300" (7.62mm) with 0.100" (2.54mm) lead spacing. T350C225K035AS has a maximum seated height of 0.331" (8.40mm) with 0.100" (2.54mm) lead spacing. These dimensional variations are within acceptable tolerances for standard PCB layouts.

Q: Are there compliance differences between equivalent parts?

A: Yes. TAP225K035SCS and 199D225X9035B1V1E3 are ROHS3 compliant. T350C225K035AS is RoHS non-compliant. Selection should account for end-product compliance requirements.

Q: What is the significance of ESR differences?

A: ESR values provided are 5 Ohm for TAP225K035SCS and T350C225K035AS, and 13 Ohm for TAP225K010SCS. ESR affects ripple current handling and thermal performance. Parts with matching ESR specifications are preferred for direct substitution in noise-sensitive or high-frequency applications.

Q: Can these parts be used interchangeably on the same PCB?

A: 199D225X9035B1V1E3 and T350C225K035AS can be used interchangeably with TAP225K035SCS from an electrical standpoint. Physical layout verification is required due to minor dimensional differences in lead spacing and height. TAP225K010SCS cannot be used interchangeably due to voltage rating mismatch.
