Engineering Selection Recommendations

Direct Equivalent Selection (Identical Specifications):

C0603C223M3RAC7867 (KEMET) is the primary direct equivalent to TMK107B7223MA-T. Both components share identical electrical specifications: 0.022 µF capacitance, 25V voltage rating, ±20% tolerance, and X7R temperature coefficient. The KEMET part is Active product status with ROHS3 compliance, providing superior availability and regulatory compliance compared to the Obsolete Taiyo Yuden original. Physical dimensions and package compatibility are confirmed across both parts.

KGM15AR71E223MM and KGM15AR71E223MT (KYOCERA AVX) provide alternative direct equivalents with identical electrical and mechanical specifications. Both are Active status with ROHS3 compliance. KGM15AR71E223MT includes Tape & Reel packaging, suitable for automated assembly processes.

Upgrade Substitute Selection (Improved Tolerance):

TMK107B7223KA-T (Taiyo Yuden) and C0603C223J3RAC7867 (KEMET) offer ±10% tolerance improvement over the original ±20% specification while maintaining 25V voltage rating and 0603 package. These upgrades provide tighter capacitance control without requiring circuit redesign. C0603C223J3RAC7867 is Active status with extensive inventory availability (99,829 pcs).

Higher Voltage Rating Substitutes (Enhanced Margin):

C0603C223J5RAC7867 (KEMET, 50V, ±5%) and C0603C223K1RAC7867 (KEMET, 100V, ±10%) provide elevated voltage ratings with improved tolerance specifications. These substitutes are suitable for applications requiring additional voltage margin or operating in higher voltage environments. Both are Active status with ROHS3 compliance.

HMK107B7223KA-T (Taiyo Yuden, 100V, ±10%) provides 100V rating with ±10% tolerance from the original manufacturer.

Compliance Considerations:

Parts marked RoHS non-compliant (06033C223KA12A, 06035C223KA12A) are acceptable only in applications where RoHS compliance is not mandated. ROHS3-compliant alternatives are preferred for new designs and regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute TMK107B7223MA-T with a higher voltage-rated capacitor such as C0603C223K1RAC7867 (100V)?

A: Yes. Higher voltage ratings are backward compatible with lower voltage circuit requirements. A 100V-rated capacitor functions correctly in a 25V application. The circuit will operate within specified parameters. Voltage rating selection should account for circuit peak voltages and safety margins.

Q: What is the difference between ±20%, ±10%, and ±5% tolerance specifications?

A: Tolerance defines the allowable deviation of actual capacitance from the nominal value. ±20% tolerance allows capacitance to range from 0.0176 µF to 0.0264 µF. ±10% tolerance ranges from 0.0198 µF to 0.0242 µF. ±5% tolerance ranges from 0.0209 µF to 0.0231 µF. Tighter tolerances provide more precise capacitance values, beneficial for applications requiring strict filtering or timing characteristics. Substitution with tighter tolerance is acceptable.

Q: Are KEMET and KYOCERA AVX parts electrically equivalent to Taiyo Yuden parts?

A: Yes, when electrical specifications match exactly. C0603C223M3RAC7867 (KEMET) and KGM15AR71E223MM (KYOCERA AVX) are electrically equivalent to TMK107B7223MA-T. All three share identical capacitance (0.022 µF), voltage rating (25V), tolerance (±20%), temperature coefficient (X7R), and package (0603). Manufacturer differences do not affect electrical performance when specifications are identical.

Q: What does X7R temperature coefficient mean?

A: X7R designates a temperature coefficient classification indicating capacitance change across the operating temperature range of -55°C to 125°C. X7R specification limits capacitance variation to ±15% across this full temperature range. This stability is critical for SMPS filtering applications where consistent capacitance is required across varying thermal conditions. All substitute parts maintain X7R specification.

Q: Can I use KGM15AR71E223MT (Tape & Reel) in place of TMK107B7223MA-T (bulk packaging)?

A: Yes. Tape & Reel packaging is a standard format for automated assembly processes. The electrical and mechanical specifications are identical to bulk-packaged equivalents. Packaging format selection depends on assembly equipment compatibility and production volume requirements. Both formats contain the same component.

Q: Why is TMK107B7223MA-T marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and no longer supports this part number. Substitute parts are necessary to maintain supply chain continuity and ensure long-term component availability for new production runs and field replacements.

Q: Is ROHS3 compliance required for my application?

A: ROHS3 compliance is mandatory for products sold in the European Union and many other regulated markets. If your application is subject to RoHS regulations, select only ROHS3-compliant alternatives. Parts marked RoHS non-compliant (06033C223KA12A, 06035C223KA12A) are restricted to non-regulated applications or legacy systems.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. Components with MSL 1 do not require special moisture-controlled storage or baking procedures prior to assembly. All substitute parts listed maintain MSL 1 specification, ensuring compatibility with standard component handling and storage practices.

Q: Can I substitute the original part with multiple different manufacturers in the same design?

A: Yes. Mixing manufacturers is acceptable when electrical and mechanical specifications are identical. However, maintaining single-source parts within a design simplifies procurement, inventory management, and quality control. If multiple manufacturers are used, ensure all parts meet identical electrical specifications and package requirements.
