TAJS475K006A Equivalent & Substitute Parts

Part Overview

The TAJS475K006A 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 designed for general-purpose applications requiring stable capacitance performance across the operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when they maintain identical electrical specifications (capacitance, voltage rating, tolerance) and mechanical compatibility (package size, mounting type) while potentially offering variations in ESR characteristics or packaging format.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAJS475K006A is determined by strict equivalence in the following parameters:

• Capacitance value: 4.7 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±10% (exact match required)
• Package: 1206 (3216 Metric) surface mount (exact match required)
• Type: Molded tantalum (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Compliance: ROHS3 and REACH status (exact match required)

Variations permitted in substitute parts include ESR (Equivalent Series Resistance) values, physical height dimensions, and packaging format (bulk versus tape & reel). These variations do not affect functional equivalence for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full compliance with ROHS3 and REACH requirements, making them suitable for applications requiring regulatory adherence.

TAJA475K006RNJ (KYOCERA AVX) offers a 1 Ohm reduction in ESR compared to the primary part while maintaining identical electrical specifications. This substitute is available in tape & reel packaging format.

293D475X96R3A2TE3 (Vishay Sprague) provides the lowest ESR at 5.5 Ohm among the three options, representing a 2 Ohm improvement over the primary part. This part is also supplied in tape & reel format and belongs to the TANTAMOUNT™ series.

Both substitute parts exhibit increased seated height (1.80 mm versus 1.20 mm for the primary part). Physical clearance verification is necessary for applications with height constraints.

Frequently Asked Questions (FAQ)

Q: Can TAJA475K006RNJ be used as a direct replacement for TAJS475K006A?

A: Yes. Both parts share identical capacitance (4.7 µF), voltage rating (6.3 V), tolerance (±10%), package (1206), and operating temperature range (-55°C to 125°C). The primary difference is ESR (6 Ohm versus 7.5 Ohm) and packaging format (tape & reel versus bulk). The lower ESR may provide improved performance in ripple current applications.

Q: What is the significance of the ESR difference between these parts?

A: ESR (Equivalent Series Resistance) affects impedance characteristics and heat dissipation under AC ripple current conditions. Lower ESR values (5.5 Ohm and 6 Ohm) result in reduced power dissipation compared to the primary part (7.5 Ohm). For general-purpose DC applications, ESR variation has minimal impact on circuit performance.

Q: Are there physical space considerations when substituting these parts?

A: Yes. The primary part (TAJS475K006A) has a maximum seated height of 1.20 mm, while both substitutes (TAJA475K006RNJ and 293D475X96R3A2TE3) have a maximum seated height of 1.80 mm. Applications with tight vertical clearance constraints must account for this 0.60 mm height difference.

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

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings. They are suitable for applications requiring regulatory compliance in these areas.

Q: What is the difference between bulk and tape & Reel packaging?

A: The primary part is supplied in bulk packaging, while the two substitutes are supplied in tape & reel (TR) format. Tape & reel packaging is standard for automated assembly processes and offers improved handling efficiency for high-volume production. Bulk packaging is typically used for lower-volume or manual assembly applications.
