T495X337M010ATE080 Molded Tantalum Capacitor Equivalent & Substitute Parts

Part Overview

The T495X337M010ATE080 is a 330 µF molded tantalum capacitor manufactured by KEMET, rated for 10 V with ±20% capacitance tolerance. This surface-mount component operates across the temperature range of -55°C to 125°C with a 2000-hour lifetime specification at 125°C. The part is classified as Active and maintains full ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be achieved within the same package footprint (2917/7343 Metric) while maintaining rated voltage, operating temperature range, and compliance certifications. Substitution becomes necessary due to inventory availability, ESR (Equivalent Series Resistance) optimization requirements, or tolerance specification adjustments for specific circuit applications.

Engineering Selection Recommendations

KEMET T495 Series Substitutes (Same Manufacturer):

T495X337K010ATE100 provides tighter capacitance tolerance (±10% versus ±20%) with higher ESR specification (100 mOhm). This part maintains ROHS3 compliance and is suitable for applications requiring improved capacitance accuracy. Higher inventory availability (5998 units) supports production continuity.

T495X337M010ATE035 maintains ±20% tolerance matching the primary part while reducing ESR to 35 mOhm. This configuration is applicable to circuits requiring lower impedance performance. ROHS3 compliance is maintained.

Cal-Chip Electronics TC Series Substitutes (Alternative Manufacturer):

Cal-Chip Electronics TC series parts (TCKIA and TCMIA designations) provide equivalent electrical performance across the specified parameter range. All Cal-Chip parts maintain RoHS compliance and MSL 1 rating. ESR variants range from 40 mOhm to 900 mOhm, accommodating diverse circuit impedance requirements.

TCKIA337ETLSR080 and TCKIA337ETLSR100 provide direct ESR matching (80 mOhm and 100 mOhm respectively) with ±10% tolerance specification. These parts are suitable for direct substitution in applications where tolerance tightening is acceptable.

TCMIA337ETLSR050 matches the primary part's ±20% tolerance with reduced ESR (50 mOhm), offering impedance optimization while maintaining tolerance specification.

Frequently Asked Questions (FAQ)

Q: Can T495X337K010ATE100 replace T495X337M010ATE080 in all applications?

A: T495X337K010ATE100 is electrically compatible within the same package footprint. The primary difference is tighter capacitance tolerance (±10% versus ±20%) and higher ESR (100 mOhm versus 80 mOhm). Applications sensitive to ESR performance may require circuit evaluation. Tolerance improvement does not create incompatibility.

Q: What is the significance of ESR variation among substitute parts?

A: ESR (Equivalent Series Resistance) affects impedance characteristics at operating frequency. Lower ESR (35-60 mOhm range) reduces voltage ripple and heat dissipation in high-frequency switching applications. Higher ESR (80-100 mOhm) is acceptable for general-purpose filtering. Circuit design specifications determine acceptable ESR range.

Q: Are Cal-Chip Electronics parts directly interchangeable with KEMET parts?

A: Cal-Chip Electronics TC series parts are mechanically and electrically compatible within the specified parameter envelope. Both manufacturers produce molded tantalum capacitors in identical 2917 (7343 Metric) package with matching dimensions and compliance certifications. PCB layout requires no modification for substitution.

Q: Does RoHS compliance differ between ROHS3 and RoHS designations?

A: ROHS3 represents the current regulatory standard (Directive 2011/65/EU as amended). RoHS Compliant indicates compliance with the original or updated RoHS directive. Both certifications are acceptable for applications requiring RoHS compliance. No functional difference exists in component performance.

Q: What is MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 indicates the component requires no special moisture control during storage, handling, or assembly. No baking or desiccant storage is required. This rating applies to all listed substitute parts, ensuring identical moisture management requirements.

Q: Can parts with ±20% tolerance be substituted for ±10% tolerance specifications?

A: ±20% tolerance parts cannot substitute for ±10% tolerance requirements. However, ±10% tolerance parts (T495X337K010ATE100, TCKIA series) can substitute for ±20% tolerance applications, providing improved accuracy margin.

Q: Are there package dimension differences between KEMET and Cal-Chip parts?

A: All listed parts conform to identical 2917 (7343 Metric) package specification: 0.287" L x 0.169" W (7.30mm x 4.30mm) with maximum seated height of 0.169" (4.30mm). No PCB footprint modification is required for cross-manufacturer substitution.
