TAJD476K020SNJ Equivalent & Substitute Parts

Part Overview

The TAJD476K020SNJ is a tantalum capacitor manufactured by KYOCERA AVX, currently in active production status. This surface-mount component is widely used in applications requiring reliable energy storage and filtering in power supply circuits, audio systems, and signal conditioning networks. Tantalum capacitors are selected for applications demanding high capacitance density, stable performance across temperature ranges, and compliance with environmental standards. Identifying equivalent and substitute parts is necessary for supply chain continuity, design flexibility, and sourcing optimization when the primary component becomes unavailable or when design requirements necessitate alternative manufacturers' offerings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJD476K020SNJ are determined by alignment of critical electrical and mechanical parameters. The substitution logic is based strictly on the following key parameters derived from component specifications:

• Capacitance Value: 47 µF
• Voltage Rating: 20 V
• Package Type: Surface Mount (2917/7343 Metric format)
• Mounting Configuration: Tape & Reel packaging for automated assembly
• Environmental Compliance: ROHS3 Compliance and REACH Unaffected status
• Moisture Sensitivity: MSL 1 (Unlimited)

Parts meeting these parameter criteria are classified as functional equivalents and direct substitutes. The Vishay Sprague 293D476X9020D2TE3 satisfies all substitution criteria through matching capacitance, voltage rating, package geometry, compliance certifications, and moisture sensitivity classification.

Engineering Selection Recommendations

The Vishay Sprague 293D476X9020D2TE3 is qualified as a direct substitute for the TAJD476K020SNJ based on the following factors:

• Both components achieve ROHS3 compliance, satisfying environmental regulatory requirements across manufacturing jurisdictions and end-market destinations.
• Both components maintain MSL 1 (Unlimited) moisture sensitivity classification, eliminating specialized handling or storage protocols and supporting standard manufacturing conditions.
• Both components carry REACH Unaffected status and EAR99 ECCN classification, ensuring unrestricted commercial availability and compliance with export control and chemical safety frameworks.
• Identical HTSUS tariff classification (8532.21.0050) confirms material composition and regulatory alignment.
• Matching capacitance value (47 µF), voltage rating (20 V), and surface-mount package configuration (2917/7343 Metric) ensure electrical and mechanical compatibility within circuit designs.

Selection between the primary KYOCERA AVX part and the Vishay Sprague substitute is determined by supply availability, cost factors, and design qualification requirements rather than technical limitations.

Frequently Asked Questions (FAQ)

Q: What makes the Vishay Sprague 293D476X9020D2TE3 a suitable substitute for the TAJD476K020SNJ?

A: Both components share identical capacitance (47 µF), voltage rating (20 V), mounting technology (surface mount), and package classification (2917/7343 Metric). Both components maintain matching environmental compliance certifications (ROHS3, REACH Unaffected) and identical moisture sensitivity levels (MSL 1). These parameters establish functional equivalence and direct substitutability.

Q: Are there any differences in performance between the two parts?

A: The Vishay Sprague part provides specified electrical parameters including ±10% tolerance, 700 mOhm ESR, and -55°C ~ 125°C operating temperature range. The KYOCERA AVX part's corresponding parameters are not provided in the available documentation. Both components meet the same compliance standards and moisture sensitivity requirements.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 classification indicates that the component has unlimited moisture absorption tolerance and does not require specialized dry-pack storage, nitrogen-flushed packaging, or time-controlled exposure limits prior to soldering. Standard storage conditions and handling procedures are applicable.

Q: Can these parts be used interchangeably in production?

A: Yes. Both components are qualified for surface-mount automated assembly in Tape & Reel packaging. Identical package dimensions (2917/7343 Metric) ensure compatibility with existing pick-and-place equipment programming and PCB layout designs. Electrical specifications alignment confirms circuit-level performance equivalence.

Q: What export and regulatory considerations apply to these components?

A: Both components are classified under ECCN EAR99, HTSUS 8532.21.0050, and carry REACH Unaffected status. These classifications confirm unrestricted commercial distribution without export licensing requirements and compliance with EU chemical safety regulations.
