Engineering Selection Recommendations

KEMET T495X Series (Same Manufacturer, Same Base Series):

The T495X477M010ATE060 provides the closest functional match with identical tolerance (±20%), lower ESR (60 mOhm vs. 80 mOhm), and ROHS3 compliance. This part is suitable for applications where reduced ESR is beneficial without changing tolerance specifications.

The T495X477K010ATE045 and T495X477K010ATE050 offer tighter tolerance (±10%) with significantly lower ESR values (45 mOhm and 50 mOhm respectively). These are applicable in designs where capacitance accuracy and lower impedance are required. The T495X477K010ATE045 is available in Cut Tape & Digi-Reel® packaging with substantially higher inventory (80,200 pcs).

The T494X477K010AT represents a different KEMET series with ±10% tolerance and 100 mOhm ESR. This part maintains ROHS3 compliance and MSL 1 rating with good inventory availability (2,324 pcs).

KYOCERA AVX TAJ Series:

The TAJE477M010SNJ matches the ±20% tolerance specification but exhibits significantly higher ESR (500 mOhm). This part is ROHS3 compliant with MSL 1 rating. The elevated ESR may impact circuit performance in applications sensitive to impedance characteristics.

KYOCERA AVX TPS Series:

The TPSE477K010R0045V provides ±10% tolerance with 45 mOhm ESR and ROHS3 compliance. However, this part carries MSL 3 (168 Hours) moisture sensitivity, requiring controlled storage and handling compared to the MSL 1 rated main part.

The TPSE477M010R0100V matches the ±20% tolerance with 100 mOhm ESR and ROHS3 compliance but also carries MSL 3 rating.

Cal-Chip Electronics TC Series:

The TCMIA477ETLSR100 provides ±20% tolerance with 100 mOhm ESR, matching the tolerance class of the main part. This part is RoHS Compliant (not ROHS3) with MSL 1 rating and high inventory (15,705 pcs).

The TCKIA477ETLSR100 and TCKIA477ETLSR200 offer ±10% tolerance with 100 mOhm and 200 mOhm ESR respectively. Both are RoHS Compliant with MSL 1 rating and excellent inventory availability (15,531 and 15,515 pcs).

Selection Criteria Summary:

For ESR-critical applications: Select T495X477K010ATE045 or T495X477K010ATE050
For tolerance-critical applications: Select any ±10% variant (T494X, T495X K-code, or Cal-Chip TCKIA series)
For cost and availability: Cal-Chip TC series offers high inventory with RoHS compliance
For ROHS3 requirement: KEMET T495X/T494X series or KYOCERA AVX TAJ/TPS series
For MSL 1 requirement: Avoid KYOCERA AVX TPS series; select KEMET or Cal-Chip alternatives

All substitute parts maintain the 2917 package footprint, -55°C to 125°C operating range, and 2000-hour lifetime at 125°C specification.

Frequently Asked Questions (FAQ)

Q: Can T495X477K010ATE045 replace T495X477M010ATE080 in my circuit?

A: Yes, provided your circuit tolerates the tolerance change from ±20% to ±10% and benefits from the lower ESR (45 mOhm vs. 80 mOhm). The capacitance value, voltage rating, package dimensions, and operating temperature range are identical. Verify that the tighter tolerance and reduced impedance do not introduce unintended circuit behavior.

Q: What is the difference between ROHS3 and RoHS Compliant ratings?

A: ROHS3 Compliant indicates compliance with the third iteration of the Restriction of Hazardous Substances directive, including additional restricted substances. RoHS Compliant indicates compliance with earlier RoHS standards. Both are acceptable for most applications; verify your specific regulatory requirements.

Q: Why do some substitutes have higher ESR values?

A: ESR (Equivalent Series Resistance) varies based on internal construction and manufacturing process. Higher ESR increases impedance and heat dissipation. Lower ESR is beneficial in high-frequency or high-current applications. Select based on your circuit's frequency response and current handling requirements.

Q: Can I use KYOCERA AVX TPS series parts as direct replacements?

A: TPSE477K010R0045V and TPSE477M010R0100V are functionally compatible but carry MSL 3 (168 Hours) moisture sensitivity versus MSL 1 (Unlimited) for the main part. MSL 3 requires controlled storage at ≤30% relative humidity and limits shelf life. Use only if your supply chain and storage conditions support MSL 3 handling.

Q: Are Cal-Chip Electronics TC series parts equivalent to KEMET?

A: Yes. TCMIA477ETLSR100, TCKIA477ETLSR100, and TCKIA477ETLSR200 are functionally equivalent with matching capacitance, voltage, package, and operating temperature. They carry RoHS Compliant (not ROHS3) certification and MSL 1 rating. Verify your design's RoHS compliance requirement before substitution.

Q: What packaging format should I select?

A: T495X477K010ATE045 is available in Cut Tape & Digi-Reel® format with the highest inventory (80,200 pcs), suitable for high-volume production. Other parts are available in standard Tape & Reel format. Select based on your assembly equipment compatibility and order quantity requirements.

Q: Can I mix different substitute parts in the same production run?

A: All listed substitutes meet the core electrical and mechanical specifications. However, mixing parts with different ESR values, tolerances, or manufacturers may introduce circuit performance variations. Establish a single approved part number per design revision to maintain consistency.

Q: What is the impact of tolerance differences on circuit performance?

A: ±20% tolerance allows capacitance variation of ±94µF to ±564µF around the 470µF nominal value. ±10% tolerance restricts variation to ±423µF to ±517µF. Tighter tolerance (±10%) is required for precision filtering, timing circuits, or applications with tight capacitance specifications. Verify your circuit's tolerance requirements before selecting a substitute.
