TAJS106M006SNJ Equivalent & Substitute Parts

Part Overview

The TAJS106M006SNJ is a 10 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 6.3 V with ±20% tolerance 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 permit tolerance relaxation, ESR optimization, or alternative manufacturer sourcing while maintaining core electrical and mechanical compatibility within the 1206 package footprint and 6.3 V rating.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity.

TAJS106K006RNJ (KYOCERA AVX): Tighter tolerance specification (±10%) provides improved capacitance accuracy over the original ±20% specification. Identical ESR and electrical performance. Suitable for applications requiring enhanced tolerance control within the same manufacturer ecosystem.

TAJA106M006RNJ (KYOCERA AVX): Maintains original tolerance and ESR specifications. Increased seated height (1.80mm vs. 1.20mm) requires PCB layout verification for clearance compatibility. Available in Cut Tape & Digi-Reel® packaging.

TPSA106M006R1500 (KYOCERA AVX): Reduced ESR specification (1.5 Ohm vs. 4 Ohm) improves high-frequency performance and reduces thermal dissipation. Increased seated height requires clearance verification. Highest inventory availability supports supply chain resilience.

293D106X06R3A2TE3 (Vishay Sprague): Cross-manufacturer alternative with ESR of 3.4 Ohm, providing intermediate performance between standard and low-ESR options. Increased seated height requires clearance verification. Highest inventory level among all alternatives.

T491A106M006AT (KEMET): Maintains original electrical specifications with 2000 Hrs @ 125°C lifetime rating. Increased seated height requires clearance verification. Supports multi-source procurement strategy.

Frequently Asked Questions (FAQ)

Q: Can TAJS106K006RNJ replace TAJS106M006SNJ directly? A: Yes. The ±10% tolerance is a tighter specification than the original ±20%, making it a direct upgrade. All electrical and mechanical parameters remain compatible within the 1206 package footprint.

Q: What is the impact of increased seated height on PCB design? A: Substitute parts with 0.071" (1.80mm) seated height versus the original 0.047" (1.20mm) require verification of PCB clearance to adjacent components, solder mask openings, and conformal coating processes. Height increase does not affect electrical performance.

Q: Why is ESR specification important for substitution? A: ESR affects impedance characteristics at high frequencies and thermal performance under ripple current conditions. Lower ESR (1.5 Ohm) improves performance; higher ESR (4 Ohm) maintains original specifications. Selection depends on circuit requirements.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original component.

Q: What packaging format differences exist among substitutes? A: Original part uses Tube packaging. Substitutes are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Packaging selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Can cross-manufacturer parts (Vishay Sprague, KEMET) be used interchangeably? A: Yes, provided PCB layout accommodates the 0.071" (1.80mm) seated height. All cross-manufacturer alternatives maintain identical electrical ratings (10 µF, 6.3 V, ±20% tolerance) and 1206 package dimensions, supporting multi-source procurement strategies.
