TAJC476K006Y Equivalent & Substitute Parts

Part Overview

The TAJC476K006Y is a 47 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 6.3 V operation in a 2312 (6032 Metric) surface mount package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical characteristics and mechanical compatibility are maintained across the specified parameter set, enabling design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on strict equivalence in the following parameters: capacitance (47 µF), tolerance (±10%), rated voltage (6.3 V), package type (2312/6032 Metric), mounting method (Surface Mount), and operating temperature range (-55°C ~ 125°C). All substitute parts maintain ROHS3 compliance and MSL Level 1 rating. Variations in ESR (Equivalent Series Resistance) and packaging format (Tape & Reel vs. Cut Tape) do not disqualify substitution when all primary electrical and mechanical parameters align. Product status must remain Active for all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with TAJC476K006Y. Selection among substitutes should be based on packaging availability (Tape & Reel or Cut Tape format), inventory status, and ESR performance requirements. Parts with lower ESR values (250 mOhm vs. 1.6 Ohm) provide improved high-frequency performance characteristics. All substitutes carry Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Moisture Sensitivity Level 1 across all parts eliminates special handling requirements during assembly and storage.

Frequently Asked Questions (FAQ)

Q: Can TAJC476K006RNJ replace TAJC476K006Y directly? A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (47 µF, ±10%, 6.3 V) and mechanical dimensions (2312 package). The difference is packaging format: TAJC476K006RNJ is supplied in Tape & Reel format while TAJC476K006Y uses standard packaging.

Q: What is the significance of ESR variation among substitute parts? A: ESR (Equivalent Series Resistance) affects high-frequency performance and ripple current handling. Parts with 250 mOhm ESR (T494C476K006AT, T495C476K006ATE250, TR3C476K6R3C0250) provide lower impedance at higher frequencies compared to 1.6 Ohm variants. Selection depends on circuit frequency requirements and ripple current specifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the main part.

Q: Does package height variation affect PCB layout? A: Seated height differences are minimal (2.79mm to 2.80mm maximum). These variations fall within standard PCB assembly tolerances and do not require layout modifications for standard applications.

Q: Can substitute parts be mixed in production? A: Yes. All substitute parts meet identical electrical and mechanical specifications within the defined parameter set. Mixed sourcing is permissible when supply constraints require component substitution during manufacturing.
