• Operating Temperature Range: -55°C to 125°C (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part 293D476X0010C2TE3 (Vishay Sprague) meets all critical electrical, mechanical, and compliance requirements for direct substitution with the T491U476M010AT.

Parameter Comparison

Engineering Selection Recommendations

The 293D476X0010C2TE3 (Vishay Sprague) is a direct electrical and mechanical substitute for the T491U476M010AT (KEMET). Both components are Active product status and maintain ROHS3 compliance and REACH unaffected status.

Substitution Basis:

• All critical electrical parameters (capacitance, voltage rating, tolerance, type) are identical
• All mechanical parameters (package, dimensions, mounting type, temperature range) are identical
• Both components meet identical compliance requirements (ROHS3, MSL 1)

Performance Consideration: The substitute part exhibits lower ESR (1.1 Ohm versus 1.4 Ohm), which represents improved electrical performance characteristics and is compatible with applications designed for the original part.

Both components are suitable for direct PCB-level substitution without design modification or circuit re-evaluation when component availability or procurement requirements necessitate part interchange.

Frequently Asked Questions (FAQ)

Q: Can the 293D476X0010C2TE3 be used as a direct replacement for the T491U476M010AT?

A: Yes. Both components share identical electrical specifications (47 µF, 10 V, ±20% tolerance), identical mechanical specifications (2312 package, surface mount, -55°C to 125°C operating range), and identical compliance certifications (ROHS3, MSL 1). Direct PCB substitution is supported without circuit modification.

Q: What is the significance of the different ESR values (1.4 Ohm vs. 1.1 Ohm)?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The substitute part's lower ESR (1.1 Ohm) indicates improved performance characteristics. This difference is compatible with applications designed for the original part and does not require design re-evaluation.

Q: Are there any height or footprint differences between these parts?

A: The footprint dimensions are identical (0.236" L x 0.126" W / 6.00mm x 3.20mm). The seated height differs: T491U476M010AT is 0.059" (1.50mm) maximum, while 293D476X0010C2TE3 is 0.110" (2.79mm) maximum. Verify PCB clearance for the substitute part in height-constrained applications.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both support identical operating temperature ranges (-55°C to 125°C).

Q: What packaging formats are available for these parts?

A: Both the T491U476M010AT and 293D476X0010C2TE3 are supplied in Tape & Reel (TR) packaging for automated assembly processes.
