TAJS475K006RNJ Equivalent & Substitute Parts

Part Overview

The TAJS475K006RNJ is a 4.7 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 6.3 V operation in a 1206 (3216 Metric) surface mount package. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific performance parameters within the allowed electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJS475K006RNJ are qualified based on strict equivalence of the following parameters:

• Capacitance: 4.7 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

Variations in ESR (Equivalent Series Resistance) and seated height are permissible within the scope of substitute qualification, as these parameters do not affect functional interchangeability in general-purpose applications. All substitute parts maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TAJS475K006RNJ, TAJA475K006RNJ, and 293D475X96R3A2TE3—are functionally equivalent for general-purpose applications requiring 4.7 µF, 6.3 V molded tantalum capacitors in 1206 package format. Selection among these parts is based on availability, inventory levels, and design-specific considerations regarding seated height and ESR performance.

TAJA475K006RNJ and 293D475X96R3A2TE3 feature reduced ESR values (6 Ohm and 5.5 Ohm respectively) compared to the main part (7.5 Ohm), which may provide performance advantages in applications sensitive to impedance characteristics. Both substitute parts maintain identical electrical ratings, temperature range, and compliance certifications.

All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.21.0050.

Frequently Asked Questions (FAQ)

Q: Can TAJA475K006RNJ be used as a direct replacement for TAJS475K006RNJ?

A: Yes. Both parts share identical electrical specifications: 4.7 µF capacitance, ±10% tolerance, 6.3 V rating, and 1206 package. The primary difference is ESR (6 Ohm versus 7.5 Ohm) and seated height (0.071" versus 0.047"), which do not affect functional interchangeability in general-purpose applications.

Q: What is the difference between KYOCERA AVX and Vishay Sprague variants?

A: Both manufacturers produce functionally equivalent 4.7 µF, 6.3 V, 1206 molded tantalum capacitors. The Vishay Sprague 293D475X96R3A2TE3 offers the lowest ESR at 5.5 Ohm. Selection depends on supply availability and design requirements for impedance performance.

Q: Are there height restrictions when substituting these parts?

A: The main part TAJS475K006RNJ has a maximum seated height of 0.047" (1.20mm), while both substitute parts measure 0.071" (1.80mm). PCB layout and component clearance must accommodate the taller profile of substitute parts.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical across all variants.

Q: What does ESR variation mean for circuit performance?

A: ESR (Equivalent Series Resistance) affects impedance characteristics at high frequencies. Lower ESR values (5.5 Ohm and 6 Ohm) provide reduced impedance compared to the main part (7.5 Ohm). For general-purpose filtering and decoupling, these variations are within acceptable operating parameters.
