Substitute Part Grouping Explanation

Substitute parts for the TAJC475K020SNJ are categorized based on the following substitution criteria:

Direct Equivalent (Same Electrical & Mechanical Specifications):

• TAJC475K020RNJ: Identical capacitance (4.7 µF), voltage rating (20 V), tolerance (±10%), ESR (1.4 Ohm), package (2312), and operating temperature range (-55°C to 125°C). Differs only in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®). Suitable for direct replacement in production environments.

Voltage Upgrade (Higher Rated Voltage, Same Capacitance & Package):

• TAJC475K050RNJ: Maintains identical capacitance (4.7 µF), tolerance (±10%), ESR (1.4 Ohm), package (2312), and operating temperature range (-55°C to 125°C). Rated voltage increased to 50 V. Provides enhanced voltage margin for applications requiring higher transient protection or design safety factor.

Cross-Manufacturer Equivalent (Alternative Manufacturer, Same Electrical & Mechanical Specifications):

• 293D475X9020C2TE3 (Vishay Sprague): Maintains identical capacitance (4.7 µF), voltage rating (20 V), tolerance (±10%), package (2312), and operating temperature range (-55°C to 125°C). ESR specified at 2.3 Ohm (higher than KYOCERA AVX reference). Provides alternative sourcing from established manufacturer.

All substitute parts maintain compliance with RoHS3 and REACH requirements, and operate within the same temperature envelope as the primary part.

Parameter Comparison

Engineering Selection Recommendations

TAJC475K020RNJ is the primary direct substitute when TAJC475K020SNJ inventory is unavailable. Both parts are manufactured by KYOCERA AVX with identical electrical specifications and package geometry. Selection between these parts depends solely on packaging format requirements (Tape & Reel vs. Cut Tape & Digi-Reel®) and procurement logistics.

TAJC475K050RNJ is selected when circuit design permits higher voltage rating. The 50 V rating provides increased safety margin in applications subject to voltage transients or where design specifications require elevated voltage headroom. Physical footprint and capacitance remain identical, enabling direct PCB placement without layout modification. ESR performance is equivalent to the primary part.

293D475X9020C2TE3 (Vishay Sprague) serves as a cross-manufacturer alternative when KYOCERA AVX parts are unavailable or when supply chain diversification is required. This part maintains electrical compatibility with identical capacitance, voltage, tolerance, and package specifications. The ESR specification of 2.3 Ohm is higher than the KYOCERA AVX reference of 1.4 Ohm; circuit performance impact depends on application-specific ripple current and thermal requirements. All parts maintain Active product status and full RoHS3 and REACH compliance.

Frequently Asked Questions (FAQ)

Q: Can TAJC475K020RNJ be used as a direct replacement for TAJC475K020SNJ?

A: Yes. Both parts are electrically and mechanically identical, with capacitance of 4.7 µF, voltage rating of 20 V, tolerance of ±10%, ESR of 1.4 Ohm, and 2312 package geometry. The only difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®). Direct PCB substitution is valid.

Q: What is the advantage of using TAJC475K050RNJ instead of TAJC475K020SNJ?

A: TAJC475K050RNJ provides a 50 V voltage rating compared to 20 V. This higher rating increases design margin for transient voltage protection and is suitable for applications where elevated voltage headroom is specified. Capacitance, tolerance, ESR, and package remain identical.

Q: Are there any performance differences between KYOCERA AVX and Vishay Sprague parts?

A: The Vishay Sprague 293D475X9020C2TE3 specifies ESR of 2.3 Ohm compared to 1.4 Ohm for KYOCERA AVX parts. This higher ESR may affect ripple current handling and thermal performance in high-frequency or high-current applications. All other electrical and mechanical parameters are equivalent.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are RoHS3 Compliant, REACH Unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). All parts maintain Active product status.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, within the constraints of electrical specifications. All parts share identical 2312 (6032 Metric) package geometry and surface mount footprint. Substitution is valid provided circuit voltage rating and ESR requirements are satisfied by the selected part.
