Key Parameters

Substitute Part Grouping Explanation

Substitution for the TARS226M010 is determined by strict equivalence in the following parameters: capacitance value (22 µF), voltage rating (10 V), mounting type (through hole), and package configuration (axial). Tolerance variations are permitted within the scope of general-purpose applications, provided the substitute maintains the same or tighter tolerance specification. Physical dimensions must remain compatible with the axial through-hole footprint.

The substitute parts are grouped into three categories:

Direct Equivalents (±20% Tolerance): Parts maintaining identical tolerance specifications to the original component.

Upgraded Equivalents (±10% Tolerance): Parts offering improved tolerance performance while maintaining all other electrical and mechanical parameters.

Manufacturer-Recommended Alternatives: Parts designated by the original manufacturer as preferred replacements, including RoHS3-compliant variants for regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Legacy Systems): The 173D226X0010W and 173D226X0010WW from Vishay Sprague TANTALEX™ 173D series provide direct electrical and mechanical equivalence to the TARS226M010. Both parts maintain ±20% tolerance and 10 V rating with identical operating temperature range. These parts are active in production and suitable for applications where the original specification must be preserved.

For Improved Performance: The 173D226X9010WW and T322C226K010AS offer ±10% tolerance, providing tighter capacitance control compared to the original ±20% specification. The T322C226K010AS additionally specifies 2.7Ohm ESR, matching the original component's ESR characteristic. Both parts are active and suitable for applications requiring enhanced capacitance stability.

For RoHS3 Compliance: The 173D226X0010WE3 and 173D226X0010WWE3 are manufacturer-recommended alternatives that maintain electrical equivalence while achieving RoHS3 compliance. These parts are necessary for designs subject to regulatory requirements prohibiting restricted substances. Both maintain ±20% tolerance and are active in production.

Product Status Consideration: All substitute parts listed are active in production, eliminating the obsolescence risk associated with the original TARS226M010. Selection should prioritize active-status components to ensure long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can 173D226X0010W and 173D226X0010WW be used interchangeably with TARS226M010?

A: Yes. Both parts maintain identical electrical specifications (22 µF, 10 V, ±20% tolerance) and axial through-hole package configuration. Physical dimensions are compatible with the original footprint. The primary difference is packaging format (Tape & Reel versus bulk), which does not affect electrical performance.

Q: What is the advantage of selecting 173D226X9010WW or T322C226K010AS over direct equivalents?

A: These parts offer ±10% tolerance instead of ±20%, providing tighter capacitance control. This improved tolerance specification is beneficial in applications where capacitance accuracy directly impacts circuit performance. The T322C226K010AS additionally specifies ESR matching the original component.

Q: Are the RoHS3-compliant variants (173D226X0010WE3 and 173D226X0010WWE3) electrically identical to non-compliant versions?

A: Yes. RoHS3 compliance refers to material composition and manufacturing process, not electrical performance. These parts maintain identical capacitance, voltage rating, tolerance, and operating temperature specifications. Selection depends on regulatory requirements applicable to the end application.

Q: What is the difference between 173D226X0010W and 173D226X0010WW?

A: Both parts are electrically identical with matching specifications. The difference is in packaging format: 173D226X0010W is supplied in standard Tape & Reel, while 173D226X0010WW is supplied in Tape & Reel with additional packaging designation. Electrical performance and footprint compatibility are identical.

Q: Can these axial tantalum capacitors be used in new designs, or are they suitable only for legacy replacement?

A: These parts are suitable for both legacy replacement and new designs. All substitute parts listed are active in production. Selection should be based on application requirements regarding tolerance, compliance status, and ESR characteristics rather than design age.

Q: How do physical dimensions affect substitution compatibility?

A: All substitute parts maintain axial through-hole configuration with compatible physical dimensions (approximately 0.180" diameter × 0.345" length). This ensures mechanical compatibility with existing PCB footprints designed for the TARS226M010. Verify specific board layout constraints if space is critical.
