Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAJS106K006SNJ is determined by the following criteria:

Primary Compatibility Parameters:

• Capacitance: 10 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Secondary Variation Parameters (Allowable Differences):

• Voltage Rating: 6.3 V (direct equivalent) or 10 V (upgrade acceptable)
• ESR: 4 Ohm (direct equivalent), 1.5 Ohm (improved performance), 2 Ohm (improved performance), 3.4 Ohm (acceptable variation)
• Packaging Format: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or Bulk
• Manufacturer: KYOCERA AVX, KEMET, Vishay Sprague (all ROHS3 compliant)
• Height - Seated: 0.047" (1.20mm) to 0.071" (1.80mm) (within 1206 package specification)

Substitutes are grouped by voltage rating and ESR performance characteristics while maintaining identical capacitance, tolerance, package, and temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating - 6.3 V):

TAJS106K006RNJ is the direct equivalent to TAJS106K006SNJ, differing only in packaging format (Tape & Reel versus Bulk). Selection between these two depends on procurement and assembly requirements.

TAJA106K006RNJ, T491A106K006AT, and TR3A106K6R3C1500 are functionally equivalent with identical electrical specifications but feature increased seated height (0.071" versus 0.047"). These are suitable for applications where PCB clearance permits the additional height.

Improved ESR Performance (Same Voltage Rating - 6.3 V):

TPSA106K006R1500 and TR3A106K6R3C1500 offer reduced ESR (1.5 Ohm) compared to the original 4 Ohm specification. These parts are suitable for applications requiring lower impedance characteristics.

T494A106K006AT provides intermediate ESR performance (2 Ohm) with KEMET manufacturing.

293D106X96R3A2TE3 (Vishay Sprague) offers ESR of 3.4 Ohm, representing a minor reduction from the original specification.

Voltage Rating Upgrade (10 V):

TAJS106K010RNJ provides a voltage rating upgrade to 10 V while maintaining all other electrical and mechanical specifications. This part is suitable for applications where higher voltage margin is required or where circuit redesign permits voltage rating increase.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status. All parts are classified as Active product status. KEMET parts include specified lifetime ratings (2000 Hrs @ 125°C).

Frequently Asked Questions (FAQ)

Q: Can TAJS106K006RNJ replace TAJS106K006SNJ directly?

A: Yes. TAJS106K006RNJ is a direct electrical and mechanical equivalent. The only difference is packaging format (Tape & Reel versus Bulk). Selection depends on assembly process requirements and procurement specifications.

Q: What is the difference between parts with 4 Ohm ESR and 1.5 Ohm ESR?

A: ESR (Equivalent Series Resistance) affects impedance characteristics and heat dissipation. Lower ESR (1.5 Ohm) provides improved performance in high-frequency or high-ripple-current applications. Both values are acceptable for general-purpose applications. Selection depends on circuit performance requirements.

Q: Can I use TAJS106K010RNJ (10 V rating) instead of TAJS106K006SNJ (6.3 V rating)?

A: Yes, provided circuit design permits the voltage rating change. The 10 V rated part maintains identical capacitance, tolerance, package, and temperature specifications. Higher voltage rating provides additional safety margin but does not alter electrical performance in circuits operating below 6.3 V.

Q: What is the significance of the height difference (0.047" versus 0.071")?

A: Both heights are within the 1206 (3216 Metric) package specification. The 0.047" height is the minimum seated height of the original part. The 0.071" height represents the maximum seated height of substitute parts. Selection depends on PCB layout clearance requirements. Verify available vertical space before substitution.

Q: Are KEMET and Vishay Sprague parts fully compatible with KYOCERA AVX parts?

A: Yes, for applications where manufacturer source is not restricted. All substitute parts from KEMET and Vishay Sprague maintain identical electrical specifications (capacitance, tolerance, voltage, temperature range), identical package dimensions (1206), and identical compliance certifications (ROHS3, MSL Level 1). Compatibility is determined by electrical and mechanical parameters, not manufacturer identity.

Q: Which substitute part offers the best availability?

A: 293D106X96R3A2TE3 (Vishay Sprague) has the highest inventory level at 100,300 pieces. TPSA106K006R1500 (KYOCERA AVX) has 26,859 pieces available. Both parts are suitable for high-volume procurement requirements.

Q: Can I mix different manufacturers in the same assembly?

A: Yes, provided all parts meet the specified electrical and mechanical parameters. All listed substitutes maintain identical capacitance (10 µF), tolerance (±10%), voltage rating (6.3 V or higher), package (1206), and temperature range (-55°C ~ 125°C). Mixing manufacturers is acceptable from an engineering compatibility standpoint.
