Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAJD226M020Y is determined by strict adherence to the following electrical and mechanical parameters:

Core Substitution Criteria:

• Capacitance: 22 µF (fixed requirement)
• Package / Case: 2917 (7343 Metric) (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Operating Temperature Range: Minimum -55°C to 125°C (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• MSL Rating: 1 (Unlimited) (fixed requirement)

Allowable Variations:

• Voltage Rating: May be equal to or greater than 20 V
• Tolerance: May be ±20% or tighter (±10%)
• ESR: May be equal to or lower than 900 mOhm
• Manufacturer: Different manufacturers permitted
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or equivalent
• Series Designation: Different series within same manufacturer or cross-manufacturer equivalents

Substitute parts are grouped into three categories: Direct Equivalents (identical electrical specifications with packaging variations), Upgrades (improved tolerance or voltage rating), and Manufacturer Recommended Alternatives (cross-manufacturer equivalents meeting all core criteria).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Packaging Variation): TAJD226M020RNJ is a direct electrical equivalent to TAJD226M020Y with identical capacitance, voltage, tolerance, and ESR specifications. The difference is packaging format (Tape & Reel versus bulk). This part is suitable for direct substitution in production environments requiring reel packaging.

Tolerance Upgrade Options: TAJD226K020RNJ, TAJD226K035RNJ, TAJY226K025RNJ, and THJD226K025RJN offer ±10% tolerance compared to the ±20% tolerance of the primary part. These upgrades maintain or exceed voltage ratings and are suitable for applications requiring tighter capacitance control.

Voltage Upgrade Options: TAJD226M025RNJ, TAJD226M035RNJ, TAJY226M025RNJ, TAJY226K025RNJ, and THJD226K025RJN provide voltage ratings of 25 V or 35 V, exceeding the 20 V requirement. These parts are suitable for designs requiring higher voltage margin or operating in elevated voltage environments.

Extended Temperature Range: THJD226K025RJN operates to 175°C (versus 125°C for standard parts) and carries AEC-Q200 automotive qualification. This part is suitable for automotive applications or high-temperature environments.

Lower ESR Alternative: 293D226X0020D2TE3 (Vishay Sprague) and T491D226M020AT (KEMET) provide ESR values of 700 mOhm and 800 mOhm respectively, compared to 900 mOhm of the primary part. These cross-manufacturer alternatives are suitable for applications sensitive to ESR performance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and surface mount 2917 package compatibility.

Frequently Asked Questions (FAQ)

Q: Can TAJD226M020RNJ replace TAJD226M020Y in all applications? A: Yes. TAJD226M020RNJ is electrically identical to TAJD226M020Y. The only difference is packaging format (Tape & Reel versus bulk). Both parts meet identical electrical specifications and are suitable for direct substitution.

Q: What is the advantage of selecting TAJD226K020RNJ over TAJD226M020Y? A: TAJD226K020RNJ offers ±10% tolerance compared to ±20% tolerance of TAJD226M020Y. This tighter tolerance is beneficial for applications requiring more precise capacitance values. Electrical performance and package dimensions remain identical.

Q: Can I use TAJD226M035RNJ in place of TAJD226M020Y? A: Yes. TAJD226M035RNJ is a suitable substitute with identical capacitance, tolerance, and ESR. The voltage rating is 35 V instead of 20 V, providing additional voltage margin. The physical package dimensions are identical.

Q: What is the difference between TAJY and TAJD series parts? A: The primary difference is the manufacturer size code (Y versus D), which affects the seated height. TAJY series parts have a maximum seated height of 0.079" (2.00mm), while TAJD series parts have 0.122" (3.10mm). Both maintain identical electrical specifications and 2917 package footprint. Selection depends on available PCB clearance.

Q: Is THJD226K025RJN suitable for non-automotive applications? A: THJD226K025RJN meets all electrical requirements for substitution and carries AEC-Q200 automotive qualification. While designed for automotive use, it is suitable for any application requiring its specifications. The extended temperature range to 175°C and automotive qualification may provide additional reliability margin for demanding environments.

Q: How do cross-manufacturer parts (Vishay, KEMET) compare to KYOCERA AVX equivalents? A: 293D226X0020D2TE3 (Vishay Sprague) and T491D226M020AT (KEMET) meet all core electrical and mechanical requirements. Both maintain 22 µF capacitance, 20 V rating, ±20% tolerance, 2917 package, and ROHS3 compliance. ESR values are 700 mOhm and 800 mOhm respectively, compared to 900 mOhm of the primary part. Cross-manufacturer selection is based on availability, supply chain considerations, and ESR performance requirements.

Q: Can I mix different substitute parts in the same design? A: All listed substitute parts maintain identical 2917 package footprints and mounting compatibility. However, mixing parts with different tolerance grades (±10% versus ±20%) or ESR values may affect circuit performance. Verify circuit design requirements before mixing substitute parts.

Q: What does MSL 1 (Unlimited) rating mean for handling? A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. This simplifies procurement and inventory management compared to higher MSL ratings.
