Substitute Part Grouping Explanation

Substitute parts for the T494D336M010AT are classified based on the following substitution criteria:

Primary Substitution Parameters:

• Capacitance: 33 µF (exact match required)
• Voltage Rating: 10 V minimum (equal or higher acceptable)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Type: Molded Tantalum (exact match required)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)
• RoHS Status: ROHS3 Compliant (compliance requirement)

Secondary Variation Parameters:

• Tolerance: ±20% or tighter (±10% acceptable as upgrade)
• ESR: 250 mOhm or higher (lower ESR acceptable as upgrade)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® (interchangeable for component selection)

Substitutes are grouped into two categories: Upgrade parts (improved electrical characteristics) and Similar parts (equivalent electrical characteristics from alternative manufacturers).

Parameter Comparison

Engineering Selection Recommendations

T491D336M010AT (KEMET): This upgrade substitute maintains identical capacitance, voltage, and tolerance specifications while offering a lower seated height (2.80 mm vs. 3.10 mm). The increased ESR of 800 mOhm is acceptable for general purpose applications. Both parts are KEMET series products with Active status and ROHS3 compliance. Packaging format differs (Cut Tape & Digi-Reel® vs. Tape & Reel), which may affect procurement logistics but does not impact component functionality.

T494D336K016AT (KEMET): This upgrade substitute provides improved voltage rating (16 V vs. 10 V) and tighter tolerance (±10% vs. ±20%) while maintaining the same ESR and package dimensions. The higher voltage rating provides additional design margin. This part is suitable for applications requiring enhanced reliability or where voltage headroom is beneficial. Both parts are KEMET T494 series with Active status and ROHS3 compliance.

293D336X0010D2TE3 (Vishay Sprague): This equivalent substitute from Vishay Sprague matches the electrical specifications (33 µF, 10 V, ±20%) with identical package footprint. The ESR of 800 mOhm is higher than the main part but acceptable for general purpose use. This part provides an alternative sourcing option from a different manufacturer while maintaining full compliance and Active product status.

TAJD336M010RNJ (KYOCERA AVX): This equivalent substitute from KYOCERA AVX matches the core electrical specifications (33 µF, 10 V, ±20%) with identical package footprint. The ESR of 1.1 Ohm is higher than the main part but acceptable for general purpose applications. This part provides cross-manufacturer compatibility while maintaining ROHS3 compliance and Active status.

All substitute parts maintain the required operating temperature range (-55°C to 125°C), surface mount configuration, and moisture sensitivity level (MSL 1 - Unlimited). Selection among these substitutes should be based on procurement availability, cost considerations, and specific application ESR requirements.

Frequently Asked Questions (FAQ)

Q: Can T491D336M010AT be used as a direct replacement for T494D336M010AT?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (10 V), tolerance (±20%), and package footprint (2917). The T491D336M010AT has a lower seated height (2.80 mm vs. 3.10 mm) and higher ESR (800 mOhm vs. 250 mOhm). The height difference may require PCB layout verification. The higher ESR is acceptable for general purpose applications.

Q: Is T494D336K016AT a suitable substitute for 10 V applications?

A: Yes. The T494D336K016AT is rated for 16 V, which exceeds the 10 V requirement of the main part. This provides additional voltage margin and is electrically compatible. The tighter tolerance (±10% vs. ±20%) is an improvement. No circuit modifications are required.

Q: Can I use TAJD336M010RNJ from KYOCERA AVX instead of the KEMET part?

A: Yes. The TAJD336M010RNJ matches the electrical specifications (33 µF, 10 V, ±20%) and package footprint (2917). The ESR is higher (1.1 Ohm vs. 250 mOhm), which is acceptable for general purpose applications. Both parts are ROHS3 compliant and have MSL 1 rating.

Q: What is the impact of different ESR values on substitution?

A: ESR affects ripple current handling and heat generation. The main part has 250 mOhm ESR. Substitutes with higher ESR (800 mOhm or 1.1 Ohm) generate more heat under AC ripple current conditions. For general purpose DC applications, higher ESR is acceptable. For high-frequency or high-ripple-current applications, verify ESR compatibility with circuit requirements.

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

A: No. The main part T494D336M010AT is supplied in Tape & Reel (TR) format. The T491D336M010AT is supplied in Cut Tape (CT) & Digi-Reel® format. Other substitutes are supplied in Tape & Reel (TR). Packaging format affects procurement and handling but does not impact component electrical performance or PCB assembly compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited) moisture sensitivity rating. All parts are classified as Active products. Compliance certifications are equivalent across all options.

Q: Can I mix different manufacturers' parts in the same assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 33 µF, 10 V, 2917 package category. Cross-manufacturer substitution is supported by matching package footprint, capacitance, voltage rating, and compliance certifications. Procurement and quality control procedures should account for multiple manufacturer sources.
