T86E337M004EBAS Equivalent & Substitute Parts

Part Overview

The T86E337M004EBAS is a 330 µF molded tantalum capacitor rated at 4 V, manufactured by Vishay Sprague as part of the TANTAMOUNT™ T86 series. This component is packaged in 2917 (7343 Metric) surface mount format with 500 mOhm equivalent series resistance and fail-safe built-in fuse protection. The part is currently obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the T86E337M004EBAS is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 330 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• Type: Molded Tantalum (exact match required)

Secondary Compatibility Parameters:

• Voltage Rating: Must be equal to or greater than 4 V
• Tolerance: ±20% or tighter acceptable
• ESR: 500 mOhm or lower acceptable

Two substitute parts meet these criteria:

1. T83E337K010EZZS (Vishay Sprague) – Upgrade substitute with higher voltage rating (10 V) and tighter tolerance (±10%), same package and ESR
2. T496X337M004AT (KEMET) – Direct equivalent with identical voltage rating (4 V) and tolerance (±20%), same package, slightly higher ESR (700 mOhm)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Electrical Equivalent): Select T496X337M004AT (KEMET) when exact electrical specifications and voltage rating matching are required. This part maintains identical capacitance (330 µF), voltage rating (4 V), tolerance (±20%), and package dimensions. The slightly elevated ESR (700 mOhm vs. 500 mOhm) remains within acceptable operational parameters for most applications. This part is currently active and ROHS3 compliant, providing improved regulatory compliance over the obsolete original.

For Upgraded Performance (Higher Voltage Margin, Tighter Tolerance): Select T83E337K010EZZS (Vishay Sprague) when design margins permit higher voltage rating and improved tolerance. The 10 V rating provides additional safety margin in 4 V applications, and ±10% tolerance offers superior capacitance stability. This part remains within the same package footprint and maintains identical ESR. Product status is active, though RoHS compliance status matches the original.

Compliance Considerations: The T496X337M004AT offers ROHS3 compliance, making it preferable for applications subject to RoHS3 regulatory requirements. Both Vishay Sprague substitutes maintain RoHS non-compliant status matching the original part.

Frequently Asked Questions (FAQ)

Q: Can T83E337K010EZZS be used as a direct drop-in replacement for T86E337M004EBAS?

A: Yes. Both parts share identical capacitance (330 µF), package (2917/7343 Metric), ESR (500 mOhm), and operating temperature range. The T83E337K010EZZS provides higher voltage rating (10 V vs. 4 V) and tighter tolerance (±10% vs. ±20%), making it functionally compatible and electrically superior for 4 V applications.

Q: What is the difference between the two substitute options?

A: T83E337K010EZZS is an upgrade substitute offering higher voltage rating and tighter tolerance from the same manufacturer (Vishay Sprague). T496X337M004AT is a direct equivalent from KEMET with matching voltage and tolerance specifications but slightly higher ESR (700 mOhm). T496X337M004AT provides ROHS3 compliance advantage.

Q: Will the higher ESR of T496X337M004AT affect circuit performance?

A: The ESR difference (700 mOhm vs. 500 mOhm) is a 40% increase. Circuit impact depends on application-specific ripple current and frequency requirements. For low-frequency or DC-biased applications, this difference is typically negligible. High-frequency switching applications should verify ESR specifications against design requirements.

Q: Are all three parts physically identical in size?

A: Yes. All three parts use the 2917 (7343 Metric) package with dimensions 0.287" L x 0.169" W (7.30mm x 4.30mm). Height specifications are equivalent (0.169" to 0.170" maximum seated height), confirming PCB footprint compatibility.

Q: Which substitute should be selected for new designs?

A: T496X337M004AT is recommended for new designs due to active product status and ROHS3 compliance. T83E337K010EZZS is suitable when Vishay Sprague sourcing is preferred or when the higher voltage rating provides system-level advantages.
