Substitute Part Grouping Explanation

Substitution of the T86E337M004ESSL is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 4 V (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 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The T496X337M004AT from KEMET meets all substitution criteria. This part maintains identical electrical specifications, physical dimensions, and environmental ratings while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The T496X337M004AT is the qualified substitute for the T86E337M004ESSL. Selection is based on the following factors:

• All critical electrical and mechanical parameters are identical
• The substitute maintains the same physical footprint and mounting compatibility
• The substitute is in active production status, ensuring long-term availability
• The substitute achieves ROHS3 compliance, whereas the original part is non-compliant
• Both parts carry identical environmental ratings and moisture sensitivity classifications

Frequently Asked Questions (FAQ)

Q: Can the T496X337M004AT be used as a direct replacement for the T86E337M004ESSL?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (4 V), tolerance (±20%), package (2917), and operating temperature range (-55°C ~ 125°C). Physical dimensions and mounting type are equivalent, enabling direct PCB substitution.

Q: What is the difference in ESR between these parts?

A: The T86E337M004ESSL has an ESR of 300 mOhm, while the T496X337M004AT has an ESR of 700 mOhm. Both values are within acceptable ranges for molded tantalum capacitors in this voltage and capacitance class. Circuit performance impact depends on specific application requirements.

Q: Why is the original part obsolete?

A: The T86E337M004ESSL is classified as obsolete by the manufacturer. The T496X337M004AT from KEMET is an active product with current manufacturing support and availability.

Q: Are there packaging differences?

A: The T496X337M004AT is supplied in Tape & Reel (TR) packaging, whereas the original part information does not specify packaging format. Both parts use the identical 2917 (7343 Metric) case size with matching physical dimensions.

Q: Is the substitute RoHS compliant?

A: The T496X337M004AT is ROHS3 compliant. The original T86E337M004ESSL is RoHS non-compliant. This difference may be relevant for applications subject to RoHS regulations.
