Substitute Part Grouping Explanation

Substitution of the T496D336M016AS is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Capacitance: 33 µF
• Voltage Rating: 16 V
• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm)
• Height - Seated (Max): 0.122" (3.10mm)
• Type: Molded Tantalum
• Features: Fail Safe with Built-in Fuse
• Operating Temperature Range: -55°C to 125°C

Allowable Variations:

• Tolerance: ±20% (main part) to ±10% (substitute) — tighter tolerance is acceptable
• ESR (Equivalent Series Resistance): Specified value in substitute is acceptable
• Packaging Format: Bulk to Tape & Reel conversion is acceptable
• Product Status: Obsolete to Active transition is the primary substitution driver
• RoHS Compliance: Non-compliant to compliant upgrade is acceptable

Two substitute parts meet these criteria and are identified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

T496D336M016ATE1K0 is the primary substitute for the T496D336M016AS. This part maintains identical electrical specifications (33 µF, ±20% tolerance, 16 V rating) and physical dimensions while offering active product status and ROHS3 compliance. The specified ESR of 1 Ohm provides additional performance data not available for the original part. Lifetime rating of 2000 Hrs @ 85°C is documented. Packaging is supplied in Tape & Reel format, suitable for automated assembly processes.

T496D336K016AT is an alternative substitute with tighter capacitance tolerance (±10% versus ±20%). All other electrical and mechanical parameters remain equivalent. This part is also active and ROHS3 compliant. The ±10% tolerance may be advantageous in applications requiring stricter capacitance control, though it does not alter functional compatibility with the original design.

Both substitutes are manufactured by KEMET within the T496 series and share the same base product number (T496D). Selection between the two substitutes depends on tolerance requirements and packaging preferences for the end application.

Frequently Asked Questions (FAQ)

Q: Can T496D336M016ATE1K0 and T496D336K016AT be used interchangeably with T496D336M016AS?

A: Both parts are electrically and mechanically equivalent to the original T496D336M016AS. They share identical capacitance (33 µF), voltage rating (16 V), package type (2917 / 7343 Metric), physical dimensions, and operating temperature range. The primary differences are product status (active versus obsolete) and compliance certifications (ROHS3 compliant versus non-compliant).

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

A: The primary difference is capacitance tolerance. T496D336M016ATE1K0 maintains ±20% tolerance matching the original part, while T496D336K016AT offers tighter ±10% tolerance. T496D336M016ATE1K0 additionally specifies ESR at 1 Ohm. Both are active products with ROHS3 compliance and 2000 Hrs @ 85°C lifetime rating.

Q: Why is the original T496D336M016AS classified as obsolete?

A: The T496D336M016AS is marked obsolete by KEMET. Active equivalent alternatives (T496D336M016ATE1K0 and T496D336K016AT) are available for new designs and production continuity.

Q: Are there packaging format differences between the main part and substitutes?

A: The original T496D336M016AS is supplied in bulk packaging, while both substitutes (T496D336M016ATE1K0 and T496D336K016AT) are supplied in Tape & Reel (TR) format. This difference does not affect electrical or mechanical compatibility; it reflects standard packaging for active production parts.

Q: Does the ±10% tolerance of T496D336K016AT affect circuit compatibility?

A: No. The ±10% tolerance of T496D336K016AT is tighter than the ±20% tolerance of the original part. Circuits designed for ±20% tolerance will operate within specification with a ±10% tolerance component. Selection of the ±10% variant may be preferred in applications requiring stricter capacitance control.

Q: What is the significance of the 1 Ohm ESR specification in T496D336M016ATE1K0?

A: ESR (Equivalent Series Resistance) is a performance parameter that affects ripple current handling and frequency response. The specified 1 Ohm ESR in T496D336M016ATE1K0 provides documented performance data. The original part does not specify ESR, so this value represents additional technical information available for the substitute.

Q: Are both substitutes RoHS compliant?

A: Yes. Both T496D336M016ATE1K0 and T496D336K016AT are ROHS3 compliant, whereas the original T496D336M016AS is RoHS non-compliant. This upgrade to compliance is acceptable for new designs and production environments with RoHS requirements.

Q: Can the substitutes be used in existing PCB designs without modification?

A: Yes. Both substitutes maintain identical physical dimensions (0.287" L x 0.169" W, 7.30mm x 4.30mm) and maximum seated height (0.122" / 3.10mm), ensuring direct footprint compatibility on existing PCBs designed for the T496D336M016AS.
