TACT476M010RTA Equivalent & Substitute Parts

Part Overview

The TACT476M010RTA is a 47 µF molded tantalum capacitor rated at 10 V, manufactured by KYOCERA AVX in the TAC series. This component is designed for general-purpose surface mount applications in the 1411 (3528 Metric) package. The part is currently active and in stock with 1,082 units available.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when specific electrical characteristics such as equivalent series resistance (ESR) must be optimized for particular circuit requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the TACT476M010RTA is determined by the following mandatory parameters:

Capacitance: 47 µF (exact match required)
Voltage Rating: 10 V (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: 1411 (3528 Metric) (exact match required)
Mounting Type: Surface Mount (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in ESR (Equivalent Series Resistance), height, packaging format (Tape & Reel vs. Cut Tape), and manufacturer series are permitted within the substitution framework, as these do not affect the fundamental functional compatibility of the capacitor in standard applications.

Engineering Selection Recommendations

All listed substitute parts are ROHS3 compliant and maintain active product status. Selection among these alternatives should be based on the following factors:

ESR Considerations: The TACT476M010RTA features 1 Ohm ESR. Direct ESR equivalents include TACT476M010XTA (1 Ohm), TAJB476M010RNJ (1 Ohm), TAJB476M010SNJ (1 Ohm), T491B476M010AT (1 Ohm), and 293D476X0010B2TE3 (1.8 Ohm). Lower ESR alternatives such as TPSB476M010R0250 (250 mOhm), TPSB476M010R0500 (500 mOhm), and TPSB476M010R0650 (650 mOhm) are available for applications requiring reduced impedance. Higher ESR alternatives such as TLJT476M010R0600 (600 mOhm) and 293D476X0010B2TE3 (1.8 Ohm) are also available.

Height Constraints: The TACT476M010RTA has a maximum seated height of 0.047" (1.20mm). Parts with identical height include TACT476M010XTA and TLJT476M010R0600. Parts with increased height of 0.083" (2.10mm) include TAJB476M010RNJ, TAJB476M010SNJ, TPSB476M010R0250, TPSB476M010R0500, TPSB476M010R0650, T491B476M010AT, and T494B476M010AT. Height compatibility must be verified against PCB layout constraints.

Packaging Format: Tape & Reel packaging is available for TACT476M010RTA, TACT476M010XTA, TAJB476M010SNJ, TLJT476M010R0600, TPSB476M010R0250, TPSB476M010R0500, TPSB476M010R0650, 293D476X0010B2TE3, and T494B476M010AT. Cut Tape & Digi-Reel packaging is available for TAJB476M010RNJ and T491B476M010AT.

Moisture Sensitivity: The TACT476M010RTA carries MSL 1 (Unlimited). All substitute parts except TLJT476M010R0600 (MSL 3, 168 Hours) maintain MSL 1 rating.

Manufacturer Availability: KYOCERA AVX parts dominate inventory with 565,200 units available for TAJB476M010RNJ. KEMET and Vishay Sprague alternatives provide additional sourcing options with 17,307 and 15,102 units respectively.

Frequently Asked Questions (FAQ)

Q: Can TAJB476M010RNJ be used as a direct replacement for TACT476M010RTA?

A: TAJB476M010RNJ meets all core electrical specifications (47 µF, 10 V, ±20%, ROHS3 compliant) and operates within the same temperature range. However, it differs in height (0.083" vs. 0.047"), packaging format (Cut Tape & Digi-Reel vs. Tape & Reel), and manufacturer series (TAJ vs. TAC). PCB layout must accommodate the increased height, and assembly processes must support the alternative packaging format.

Q: What is the difference between TPSB476M010R0650 and TACT476M010RTA?

A: Both parts share identical capacitance (47 µF), voltage rating (10 V), tolerance (±20%), and operating temperature range (-55°C to 125°C). The primary differences are ESR (650 mOhm vs. 1 Ohm), height (0.083" vs. 0.047"), and manufacturer series (TPS vs. TAC). The lower ESR of TPSB476M010R0650 reduces impedance, which may benefit high-frequency or high-current applications. The increased height requires PCB layout verification.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. This ensures compatibility with environmental and regulatory requirements equivalent to the original TACT476M010RTA.

Q: Which substitute part has the lowest ESR?

A: TPSB476M010R0250 offers the lowest ESR at 250 mOhm, followed by TPSB476M010R0500 at 500 mOhm and TPSB476M010R0650 at 650 mOhm. These parts are suitable for applications requiring minimal impedance.

Q: Can I use a part with different height in my design?

A: Height compatibility depends on PCB layout and available vertical clearance. The TACT476M010RTA has a maximum height of 0.047" (1.20mm). Substitute parts with 0.083" (2.10mm) height require verification that the PCB design accommodates this increase. Parts with identical height (TACT476M010XTA, TLJT476M010R0600) are preferred when space is constrained.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging is continuous and suitable for high-volume automated assembly. Cut Tape & Digi-Reel packaging is pre-cut and suitable for lower-volume or mixed-component assembly processes. Selection depends on manufacturing equipment and production volume requirements.

Q: Is TLJT476M010R0600 suitable as a substitute despite MSL 3 rating?

A: TLJT476M010R0600 carries MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for TACT476M010RTA. MSL 3 requires moisture bake-out procedures before soldering if the part has been exposed to humidity for extended periods. This introduces additional manufacturing steps and is not recommended unless other factors necessitate its use.

Q: Which substitute offers the best inventory availability?

A: TAJB476M010RNJ offers the highest inventory with 565,200 units available, followed by T491B476M010AT with 17,307 units and 293D476X0010B2TE3 with 15,102 units. High inventory availability reduces lead time risk for procurement.
