TACK225M003Q Equivalent & Substitute Parts

Part Overview

The TACK225M003Q is a 2.2 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 3 V operation in a 0402 (1005 Metric) surface mount package. This component is classified as Active product status and is suitable for general-purpose applications requiring compact form factor and low ESR characteristics.

Substitute parts become necessary when the original component reaches end-of-life status, inventory constraints occur, or design requirements permit operation at higher voltage ratings while maintaining electrical compatibility. The parts listed below provide functional equivalence based on matching capacitance, tolerance, ESR, package dimensions, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TACK225M003Q is determined by the following criteria:

Primary Matching Parameters:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Molded tantalum (exact match required)
• ESR: 15 Ohm (exact match required)
• Operating Temperature: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 3 V (uprating permitted)
• Package / Case: 0402 (1005 Metric) or 0402 (1106 Metric) with compatible footprint
• Height - Seated: Variation permitted within PCB assembly constraints
• MSL Rating: May be equal to or lower MSL value (more stringent handling acceptable)
• Product Status: Active or Not For New Designs (both acceptable for substitution)

The substitute parts listed below satisfy all primary matching parameters and allowable variations.

Parameter Comparison

Engineering Selection Recommendations

TACK225M006QTA (KYOCERA AVX) is the primary substitute for the TACK225M003Q. This part maintains identical package dimensions (0402 1005 Metric), identical height profile, and identical MSL rating. The voltage rating is increased to 6.3 V, which is compatible with 3 V circuit requirements. Product status is Active, ensuring continued availability and support.

298D225X0010K2T (Vishay Sprague MICROTAN® series) provides an alternative from a different manufacturer. This part matches the 0402 (1005 Metric) package footprint and maintains all electrical parameters. The voltage rating is increased to 10 V. Product status is Active. Height is reduced to 0.024", which may provide assembly advantages in space-constrained designs.

F981A225MUA (KYOCERA AVX) is listed as Not For New Designs and carries an MSL rating of 3 (168 Hours), requiring more stringent moisture handling compared to the original part. The package footprint differs slightly (0402 1106 Metric with 1.10mm x 0.60mm dimensions), which may require PCB layout verification. This part is suitable only for legacy design maintenance or when inventory constraints necessitate its use.

Frequently Asked Questions (FAQ)

Q: Can TACK225M006QTA be used as a direct replacement for TACK225M003Q?

A: Yes. The TACK225M006QTA is electrically and mechanically compatible. Both parts share identical capacitance (2.2 µF), tolerance (±20%), ESR (15 Ohm), operating temperature range (-55 to 125°C), package footprint (0402 1005 Metric), and MSL rating (1). The higher voltage rating (6.3 V vs. 3 V) does not prevent substitution in 3 V circuits.

Q: What is the difference between the 0402 (1005 Metric) and 0402 (1106 Metric) packages?

A: The 0402 (1005 Metric) package has dimensions of 1.00mm x 0.50mm, while the 0402 (1106 Metric) package has dimensions of 1.10mm x 0.60mm. The F981A225MUA uses the larger 1106 Metric variant. PCB footprint compatibility must be verified before substitution, as the larger package may not fit existing pad layouts designed for the 1005 Metric variant.

Q: Why does F981A225MUA have an MSL rating of 3 instead of 1?

A: MSL (Moisture Sensitivity Level) rating indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 allows unlimited storage time, while MSL 3 limits exposure to 168 hours. F981A225MUA requires more stringent moisture control during handling and storage. This does not affect electrical performance but requires adherence to specific storage and assembly protocols.

Q: Is 298D225X0010K2T from Vishay Sprague compatible with the original KYOCERA AVX part?

A: Yes. The 298D225X0010K2T matches all critical electrical parameters (2.2 µF, ±20%, 15 Ohm ESR, -55 to 125°C) and uses the same 0402 (1005 Metric) package footprint. The manufacturer difference does not affect compatibility. The reduced height (0.024" vs. 0.028") may provide assembly benefits in compact designs.

Q: Can I use a 10 V rated capacitor in a 3 V circuit?

A: Yes. Voltage rating indicates the maximum voltage the capacitor can safely withstand. Using a capacitor with a higher voltage rating in a lower voltage circuit is electrically safe and does not degrade performance. Both 298D225X0010K2T and F981A225MUA are rated for 10 V and are suitable for 3 V applications.

Q: What compliance certifications apply to all substitute parts?

A: All listed parts are ROHS3 Compliant and REACH Unaffected, matching the original TACK225M003Q specifications. These certifications ensure environmental and regulatory compliance across all substitute options.
