Key Parameters

Substitute Part Grouping Explanation

Substitution for the T86E337M004ESAS is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Operating Temperature Range: -55°C to 125°C (thermal compatibility)

Two substitute parts meet these core criteria:

Upgrade Substitute (T83E337K010EZZS): Maintains identical capacitance, package, and mounting specifications while offering improved voltage rating (10 V vs. 4 V) and tighter tolerance (±10% vs. ±20%). This part is active in production status.

Direct Equivalent (T496X337M004AT): Manufactured by KEMET, this part matches the original specifications exactly in capacitance, voltage rating, tolerance, and package. It differs in ESR (700 mOhm vs. 500 mOhm) and includes RoHS3 compliance certification.

Engineering Selection Recommendations

For Direct Replacement: The T496X337M004AT from KEMET provides electrical and mechanical equivalence to the T86E337M004ESAS. Both parts share identical capacitance, voltage rating, tolerance, and package specifications. The T496X337M004AT is currently in active production status and carries RoHS3 compliance certification, offering improved regulatory alignment compared to the obsolete original part.

For Upgraded Performance: The T83E337K010EZZS from Vishay Sprague offers enhanced specifications through increased voltage rating (10 V) and improved tolerance (±10%). This part maintains identical ESR and package compatibility while providing design margin for voltage-sensitive applications. The T83E337K010EZZS is active in production status.

Both substitute parts are qualified for the same operating temperature range and moisture sensitivity level as the original component, ensuring thermal and environmental compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the T83E337K010EZZS be used as a direct replacement for the T86E337M004ESAS?

A: Yes. The T83E337K010EZZS maintains identical capacitance (330 µF), package (2917), mounting type (surface mount), and ESR (500 mOhm). The higher voltage rating (10 V vs. 4 V) and tighter tolerance (±10% vs. ±20%) represent improvements that do not compromise compatibility in circuits designed for the original 4 V specification.

Q: What is the difference between the T496X337M004AT and the original T86E337M004ESAS?

A: The T496X337M004AT matches the original part in all critical electrical parameters: capacitance, voltage rating, tolerance, and package. The primary differences are manufacturer (KEMET vs. Vishay Sprague), ESR (700 mOhm vs. 500 mOhm), and RoHS compliance status (RoHS3 vs. non-compliant). The higher ESR may affect performance in applications with strict ripple current or thermal dissipation requirements.

Q: Are all substitute parts available in the same package size?

A: Yes. All three parts use the 2917 (7343 Metric) surface mount package with identical footprint dimensions (0.287" L x 0.169" W / 7.30 mm x 4.30 mm), ensuring direct PCB compatibility without layout modifications.

Q: Which substitute part should be selected for new designs?

A: Selection depends on design requirements. For voltage margin and tighter tolerance, the T83E337K010EZZS is preferred. For exact electrical equivalence with regulatory compliance, the T496X337M004AT is appropriate. Both parts are in active production status.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. All three parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
