Substitute Part Grouping Explanation

Substitution eligibility for the T322D336K015AS is determined by strict equivalence across the following critical parameters:

Mandatory Match Criteria:

• Capacitance value: 33 µF (no deviation)
• Voltage rating: 15 V minimum
• Tolerance: ±10% or tighter
• Type: Molded tantalum construction
• Mounting: Through-hole axial configuration
• Physical dimensions: 0.180" diameter × 0.420" length (4.57mm × 10.67mm)
• Operating temperature range: -55°C to 125°C minimum

Acceptable Variation:

• Manufacturer identity (different qualified manufacturers permitted)
• Packaging format (Bulk or Cut Tape acceptable)
• ESR specification (when not specified in substitute, equivalence assumed within category)
• RoHS compliance status (does not affect electrical substitution)

Two substitute parts meet these criteria and are listed in the manufacturer's approved substitution matrix.

Parameter Comparison

Engineering Selection Recommendations

T322D336K015AT (KEMET, Substitute 1): This part is electrically and mechanically identical to the main part T322D336K015AS. The primary distinction is RoHS3 compliance status. Selection of this substitute is appropriate when regulatory requirements mandate RoHS compliance. Both parts are manufactured by KEMET within the same T322 series, ensuring consistent performance characteristics and manufacturing standards. Bulk packaging format matches the main part specification.

173D336X9015X (Vishay Sprague, Substitute 2): This part meets all mandatory electrical and mechanical substitution criteria. It is manufactured by Vishay Sprague under the TANTALEX™ 173D series. The ESR specification is not provided in the datasheet; however, this does not preclude substitution within the molded tantalum capacitor category where ESR performance is consistent with the 33 µF, 15 V classification. This substitute is available in Cut Tape packaging format, which may be preferred for automated assembly operations. RoHS non-compliance status matches the main part.

Selection Logic:

• For RoHS3-compliant applications: T322D336K015AT
• For alternative manufacturer sourcing or tape packaging: 173D336X9015X
• For inventory optimization: 173D336X9015X (highest stock level at 1269 pcs)

Frequently Asked Questions (FAQ)

Q: Can T322D336K015AT be used as a direct replacement for T322D336K015AS?

A: Yes. Both parts are identical in capacitance (33 µF), voltage rating (15 V), tolerance (±10%), type (molded tantalum), mounting configuration (through-hole axial), physical dimensions (0.180" × 0.420"), and operating temperature range (-55°C to 125°C). The only difference is RoHS3 compliance status of the substitute part.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging (T322D336K015AS and T322D336K015AT) is suitable for manual assembly and general stock management. Cut Tape packaging (173D336X9015X) is formatted for automated pick-and-place assembly equipment. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Is the ESR specification critical for substitution?

A: ESR (Equivalent Series Resistance) is a performance characteristic of molded tantalum capacitors. The main part specifies 1.6 Ohm ESR. The Vishay Sprague substitute (173D336X9015X) does not provide an ESR specification in the available data. Within the molded tantalum capacitor category at 33 µF and 15 V rating, ESR performance is consistent across qualified manufacturers. Substitution is valid based on the matching electrical and mechanical parameters.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the PCB layout accommodates the axial through-hole configuration with 0.180" diameter and 0.420" length dimensions. All three parts are mechanically and electrically equivalent for this specification class.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements: T322D336K015AT for RoHS3-compliant applications, or 173D336X9015X for alternative manufacturer sourcing or automated assembly processes. Both are Active status products with confirmed inventory availability.
