TAC476K010P06 Equivalent & Substitute Parts

Part Overview

The TAC476K010P06 is a 47 µF molded tantalum capacitor rated at 10 V with ±10% tolerance, manufactured by Cornell Dubilier Electronics (CDE) in axial through-hole configuration. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 125°C and is suitable for general-purpose applications requiring axial-lead tantalum capacitors with these electrical specifications.

Substitute Part Grouping Explanation

Substitution of the TAC476K010P06 is determined by strict equivalence in the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 47 µF (exact match required)
Voltage Rating: 10 V (exact match required)
Tolerance: ±10% (exact match required)
Package Type: Axial through-hole (exact match required)
Physical Dimensions: 0.180" Dia x 0.420" L (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)

Direct Substitutes maintain all primary criteria and differ only in packaging format (Tape & Box, Tape & Reel, Cut Tape, or Bulk) or manufacturer designation. These parts are functionally and mechanically interchangeable.

Upgrade Substitutes improve upon the original specification by reducing tolerance to ±5% while maintaining all other electrical and mechanical parameters. These provide enhanced capacitance accuracy for applications requiring tighter tolerances.

Similar Parts share the same capacitance, voltage, and physical dimensions but differ in tolerance specification (±20%) or compliance status. These are suitable only when the application permits wider tolerance ranges.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Immediate Replacement):

The following parts provide direct functional and mechanical equivalence to the TAC476K010P06:

173D476X9010X (Vishay Sprague, Tape & Box): Active status, maintains all electrical specifications and physical dimensions. Suitable for standard procurement and assembly processes.
173D476X9010XW (Vishay Sprague, Tape & Reel): Active status, identical electrical specifications. Recommended for high-volume automated assembly requiring reel packaging.
T322D476K010AS (KEMET, Bulk): Active status, provides specified ESR of 1.7 Ω. Suitable for applications where ESR characteristics are critical.
173D476X9010XE3 (Vishay Sprague, Cut Tape): Active status with ROHS3 compliance. Recommended for designs requiring RoHS compliance documentation.
T322D476K010AT (KEMET, Bulk): Active status with ROHS3 compliance and 1.7 Ω ESR specification. Recommended for RoHS-compliant designs requiring defined ESR performance.

Upgrade Substitute (Enhanced Tolerance):

173D476X5010X (Vishay Sprague, Tape & Box): Provides ±5% tolerance versus the original ±10%, improving capacitance accuracy while maintaining all other specifications. Suitable for applications requiring tighter capacitance tolerances.

Similar Parts (Conditional Use):

173D476X0010XWE3 (Vishay Sprague, Tape & Reel): Offers ±20% tolerance and ROHS3 compliance. Suitable only for applications where wider tolerance ranges are acceptable.

Selection should prioritize active-status parts to ensure long-term availability and supply chain continuity. ROHS3-compliant variants are recommended for new designs or applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can I use 173D476X9010XE3 as a direct replacement for TAC476K010P06?

A: Yes. The 173D476X9010XE3 maintains identical electrical specifications (47 µF, 10 V, ±10% tolerance) and physical dimensions (0.180" Dia x 0.420" L). The difference is packaging format (Cut Tape versus axial bulk) and RoHS compliance status (ROHS3 Compliant). Mechanical and electrical compatibility is confirmed.

Q: What is the difference between the Vishay Sprague and KEMET substitutes?

A: Both manufacturers provide 47 µF, 10 V, ±10% axial tantalum capacitors with identical physical dimensions. KEMET parts (T322D476K010AS and T322D476K010AT) specify ESR of 1.7 Ω, while Vishay Sprague parts do not provide ESR values in the available data. Selection depends on whether ESR specification is required for the application and packaging preference (Bulk versus Tape & Box/Tape & Reel/Cut Tape).

Q: Is the 173D476X5010X upgrade suitable for my application?

A: The 173D476X5010X is suitable if your application benefits from improved capacitance tolerance (±5% versus ±10%). All other electrical and mechanical parameters remain identical to the original TAC476K010P06. This upgrade is recommended for precision analog circuits or applications with tight capacitance requirements.

Q: Why does 173D476X0010XWE3 have ±20% tolerance?

A: The 173D476X0010XWE3 is classified as a similar part rather than a direct substitute due to its ±20% tolerance specification, which is wider than the original ±10%. This part is suitable only for applications where capacitance tolerance is not critical. It offers the advantage of ROHS3 compliance.

Q: What packaging format should I select?

A: Packaging selection depends on assembly process requirements. Tape & Box (TB) and Tape & Reel (TR) formats are suitable for automated assembly. Cut Tape (CT) is appropriate for manual or semi-automated processes. Bulk packaging is suitable for manual assembly or custom packaging requirements. All formats maintain identical electrical and mechanical specifications.

Q: Are all substitute parts RoHS compliant?

A: No. The original TAC476K010P06 and most direct substitutes (173D476X9010X, 173D476X9010XW, T322D476K010AS) are RoHS non-compliant. ROHS3-compliant alternatives are available: 173D476X9010XE3, 173D476X0010XWE3, and T322D476K010AT. Select compliant variants for designs subject to environmental regulations.

Q: Can I mix different manufacturers in the same design?

A: Yes. All substitute parts maintain identical electrical specifications (47 µF, 10 V, ±10% tolerance) and physical dimensions. Mixing manufacturers is acceptable from an electrical and mechanical standpoint. However, verify ESR requirements if specified in your design, as KEMET parts provide 1.7 Ω ESR while Vishay Sprague parts do not specify this parameter.
