Equivalent & Substitute Parts for TAC335K015P02

Part Overview

The TAC335K015P02 is a 3.3 µF molded tantalum axial capacitor rated at 15 V, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making direct replacement necessary for ongoing production and repair applications. The part operates across a temperature range of -55°C to 125°C and is designed for general-purpose through-hole mounting in axial configuration with dimensions of 0.110" diameter by 0.290" length (2.79mm x 7.37mm).

Due to its obsolete status, equivalent and substitute parts from active manufacturers are required to maintain design continuity and ensure component availability for new builds and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAC335K015P02 is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria (Must Match):

• Capacitance: 3.3 µF
• Voltage Rating: 15 V (minimum)
• Tolerance: ±10%
• Type: Molded Tantalum
• Mounting Type: Through Hole
• Package/Case: Axial
• Size/Dimension: 0.110" Dia x 0.290" L (2.79mm x 7.37mm)
• Operating Temperature Range: -55°C to 125°C

Substitution Categories:

Direct Equivalents (15 V Rating): Parts meeting all primary criteria with identical voltage rating. These include 173D335X9015V, 173D335X9015VW, T322B335K015AS, 173D335X9015VE3, and T322B335K015AT. All maintain the same electrical and mechanical specifications as the original part.

Voltage Upgrades (20 V and 25 V Ratings): Parts with higher voltage ratings (173D335X9020VW, 173D335X9025VW, T322B335K020AS, T322B335K025AS) are electrically compatible for circuits designed for 15 V operation, as they provide additional voltage margin while maintaining identical capacitance, tolerance, physical dimensions, and temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (15 V Equivalent):

Select from active-status parts with identical 15 V voltage rating: 173D335X9015V, 173D335X9015VW, T322B335K015AS, 173D335X9015VE3, or T322B335K015AT. All maintain electrical and mechanical compatibility with the original TAC335K015P02 specification.

Packaging Considerations:

• Tape & Reel (TR) Format: 173D335X9015VW and 173D335X9020VW are suitable for automated assembly processes requiring continuous reel feeding.
• Tape & Box (TB) Format: 173D335X9015V and 173D335X9015VE3 are appropriate for manual assembly or lower-volume production runs.
• Bulk Format: T322B335K015AS, T322B335K015AT, T322B335K020AS, and T322B335K025AS are supplied in bulk packaging for component kitting and inventory management.

RoHS Compliance:

The original TAC335K015P02 is RoHS non-compliant. For applications requiring RoHS3 compliance, select 173D335X9015VE3 or T322B335K015AT, both of which are RoHS3 compliant while maintaining all electrical and mechanical specifications.

Voltage Upgrade Path:

For circuits with design margin requirements, 20 V and 25 V rated alternatives (173D335X9020VW, 173D335X9025VW, T322B335K020AS, T322B335K025AS) provide enhanced voltage headroom while preserving identical capacitance, tolerance, physical dimensions, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a 20 V or 25 V rated capacitor in place of the 15 V TAC335K015P02?

A: Yes. Higher voltage-rated capacitors with identical capacitance, tolerance, physical dimensions, and temperature range are electrically compatible for 15 V circuit applications. The higher voltage rating provides additional safety margin without affecting circuit performance.

Q: What is the difference between Tape & Reel, Tape & Box, and Bulk packaging?

A: Tape & Reel (TR) packaging is continuous reel format for automated pick-and-place assembly. Tape & Box (TB) packaging combines tape format with a protective box for manual or semi-automated assembly. Bulk packaging supplies loose components for manual kitting and inventory management. All three formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are KEMET T322 series parts direct equivalents to the CDE TAC335K015P02?

A: Yes. KEMET T322B335K015AS and T322B335K015AT are direct electrical and mechanical equivalents with identical capacitance (3.3 µF), voltage rating (15 V), tolerance (±10%), physical dimensions (0.110" Dia x 0.290" L), and operating temperature range (-55°C to 125°C). Both are active-status products suitable for replacement applications.

Q: What is the significance of ESR (Equivalent Series Resistance) values in the KEMET parts?

A: ESR values (6 Ohm for 15 V parts, 5.5 Ohm for 20 V parts, 5 Ohm for 25 V parts) are provided specifications for KEMET T322 series components. These values characterize the internal resistance of the capacitor and are relevant for high-frequency or high-current applications. For general-purpose applications, ESR differences between manufacturers do not affect functional compatibility.

Q: Why is the original TAC335K015P02 marked as obsolete?

A: Obsolete status indicates that Cornell Dubilier Electronics has discontinued manufacturing this part. Active-status alternatives from Vishay Sprague and KEMET provide equivalent electrical and mechanical performance with ongoing manufacturing support and availability.

Q: Can I mix different manufacturers' parts in the same circuit board design?

A: Yes. All substitute parts listed meet identical electrical specifications (3.3 µF, 15 V, ±10% tolerance) and physical dimensions (0.110" Dia x 0.290" L). Mixing manufacturers is acceptable from an engineering standpoint, though procurement and inventory management may benefit from standardizing on a single manufacturer per design revision.

Q: What does RoHS3 compliance mean for these capacitors?

A: RoHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements, restricting use of lead, cadmium, mercury, and other hazardous materials. The original TAC335K015P02 is RoHS non-compliant. For applications requiring RoHS3 certification, 173D335X9015VE3 and T322B335K015AT are compliant alternatives.
