Parameter Comparison

Engineering Selection Recommendations

KEMET Series T495 and T494 (Same Manufacturer): The T495X477K010ATE045, T495X477K010ATE050, and T494X477K010AT are direct KEMET alternatives with identical electrical specifications and thermal performance. These parts maintain ROHS3 compliance and MSL 1 rating. Selection between these variants depends on ESR requirements: T495X477K010ATE045 (45 mOhm) for lowest ESR applications, T495X477K010ATE050 (50 mOhm) for moderate ESR, T494X477K010AT (100 mOhm) for higher ESR tolerance. The T495X477K010ATE045 offers the highest inventory availability (80200 pcs) and is available in Cut Tape & Digi-Reel® packaging.

Cal-Chip Electronics, Inc. TCKIA Series: The TCKIA477ETLSR100 and TCKIA477ETLSR200 provide alternative sourcing from Cal-Chip Electronics with RoHS compliance. Both maintain identical capacitance, voltage, tolerance, and thermal specifications. The TCKIA477ETLSR100 (100 mOhm) aligns with the T494X477K010AT ESR specification, while TCKIA477ETLSR200 (200 mOhm) accommodates higher ESR tolerance applications. Both parts carry substantial inventory (15531 and 15515 pcs respectively).

KYOCERA AVX TPSE Series: The TPSE477K010R0045V offers the lowest ESR (45 mOhm) matching the T495X477K010ATE045 performance. This part maintains ROHS3 compliance but carries MSL 3 (168 Hours) moisture sensitivity, requiring controlled storage and handling compared to MSL 1 alternatives. Selection of this part is appropriate when ESR performance is critical and moisture sensitivity management is feasible.

All substitute parts are active products with confirmed inventory availability and meet the specified electrical and thermal requirements of the T495X477K010ATE080.

Frequently Asked Questions (FAQ)

Q: Can I substitute T495X477K010ATE080 with T495X477K010ATE045?

A: Yes. Both parts share identical capacitance (470 µF), voltage rating (10 V), tolerance (±10%), package (2917), and thermal specifications. The primary difference is ESR: T495X477K010ATE045 operates at 45 mOhm versus 80 mOhm for the original part. Lower ESR reduces impedance and heat generation. The T495X477K010ATE045 is available in Cut Tape & Digi-Reel® packaging versus Tape & Reel for the original part.

Q: What is the difference between KEMET and Cal-Chip Electronics alternatives?

A: Both manufacturers provide 470 µF, 10 V molded tantalum capacitors in the 2917 package with identical thermal performance. KEMET parts maintain ROHS3 compliance, while Cal-Chip Electronics parts are RoHS compliant. ESR variants differ: KEMET offers 45, 50, and 100 mOhm options; Cal-Chip offers 100 and 200 mOhm options. Selection depends on ESR requirements and preferred manufacturer sourcing.

Q: Why does TPSE477K010R0045V have MSL 3 instead of MSL 1?

A: MSL (Moisture Sensitivity Level) indicates moisture absorption characteristics during storage. MSL 1 (Unlimited) allows indefinite storage without baking, while MSL 3 (168 Hours) requires controlled humidity storage and baking before reflow soldering if exposed to moisture. The TPSE477K010R0045V from KYOCERA AVX carries MSL 3 classification. This does not affect electrical performance but requires adherence to moisture handling procedures during assembly.

Q: Can I use a substitute with higher ESR than the original part?

A: ESR substitution depends on circuit requirements. Higher ESR increases impedance and heat dissipation. The T494X477K010AT (100 mOhm) and TCKIA477ETLSR100 (100 mOhm) have higher ESR than the original T495X477K010ATE080 (80 mOhm). The TCKIA477ETLSR200 (200 mOhm) has significantly higher ESR. Substitution is permissible only if the application circuit tolerates the increased impedance and thermal characteristics.

Q: Are all substitute parts available in the same packaging format?

A: No. The original T495X477K010ATE080 is supplied in Tape & Reel (TR) format. The T495X477K010ATE045 is available in Cut Tape (CT) & Digi-Reel® format, which may require different handling in automated assembly equipment. All other substitutes are supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly line compatibility and procurement requirements.

Q: What is the inventory status of substitute parts?

A: The T495X477K010ATE045 has the highest availability (80200 pcs), followed by Cal-Chip Electronics parts (15531 and 15515 pcs). The original T495X477K010ATE080 has 1037 pcs in stock. When procurement requires large quantities or extended lead times, the T495X477K010ATE045 or Cal-Chip alternatives provide superior availability.

Q: Do all substitute parts meet the same thermal specifications?

A: Yes. All substitute parts operate across -55°C to 125°C and maintain a rated lifetime of 2000 hours at 125°C. Thermal performance is identical across all alternatives. ESR differences affect heat generation during operation but do not change the rated operating temperature range or lifetime specification.
