TACT476K010XTA Equivalent & Substitute Parts

Part Overview

The TACT476K010XTA is a 47 µF molded tantalum capacitor rated at 10 V, manufactured by KYOCERA AVX in the 1411 (3528 Metric) package. This component is classified as Active and complies with ROHS3 and REACH standards. Substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance) and mechanical compatibility (package, case size, mounting type). Alternative sources and packaging formats are available from both KYOCERA AVX and Vishay Sprague product lines.

Substitute Part Grouping Explanation

Substitution eligibility is determined by three critical parameters: capacitance value (47 µF), voltage rating (10 V), and package form factor (1411/3528 Metric). All listed substitute parts match these core electrical and mechanical specifications. Variations in ESR (Equivalent Series Resistance) and packaging format (Cut Tape vs. Tape & Reel) do not affect functional interchangeability in standard applications. Substitute parts are grouped by manufacturer and series designation while maintaining identical capacitance, voltage, tolerance, and case dimensions.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. Selection between KYOCERA AVX and Vishay Sprague alternatives depends on supply chain requirements and packaging format availability. KYOCERA AVX TAJ and TPS series parts offer lower ESR options (250 mOhm to 650 mOhm) compared to the original TACT series (1 Ohm). Vishay Sprague 293D, 593D, and TR3 series parts provide ESR values ranging from 350 mOhm to 1.8 Ohm. All parts share identical case dimensions (0.138" L × 0.110" W / 4.60 mm × 2.80 mm) and operate across the full temperature range (-55°C to 125°C). Packaging format differences (Cut Tape & Digi-Reel versus Tape & Reel) affect procurement and assembly processes but not electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TAJB476K010RNJ replace TACT476K010XTA directly? A: Yes. Both parts share identical capacitance (47 µF), voltage rating (10 V), tolerance (±10%), and package form factor (1411/3528 Metric). The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and a slight height increase (2.10 mm versus 1.20 mm). Verify PCB clearance for the increased height.

Q: What is the significance of ESR variation among substitute parts? A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance but does not alter capacitance or voltage rating. The original TACT476K010XTA specifies 1 Ohm ESR. Substitute parts with lower ESR (250 mOhm to 650 mOhm) provide improved performance in high-frequency applications. Parts with higher ESR (1.8 Ohm) maintain compatibility for standard applications.

Q: Are Vishay Sprague parts electrically equivalent to KYOCERA AVX parts? A: Yes. All Vishay Sprague substitute parts (293D, 593D, TR3 series) match the core electrical specifications: 47 µF capacitance, 10 V rating, ±10% tolerance, and 1411 package. Height dimensions are marginally different (2.11 mm versus 2.10 mm for KYOCERA AVX), which is negligible for most applications.

Q: Does packaging format affect electrical performance? A: No. Cut Tape & Digi-Reel and Tape & Reel formats are procurement and assembly considerations only. Electrical characteristics remain identical across all packaging options.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, matching the original TACT476K010XTA compliance profile.
