Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection among substitutes is determined by application-specific requirements:

KYOCERA AVX TAJ Series (TAJS475M016RNJ, TAJS475K016RNJ, TAJA475M016RNJ, TCA1C475M8R, TPSA475M016R2000): Direct manufacturer alternatives with identical electrical ratings. TAJS475K016RNJ provides tolerance upgrade to ±10%. TPSA475M016R2000 offers lowest ESR at 2.0 Ohm for applications requiring reduced impedance.

Vishay Sprague 293D Series (293D475X0016A2TE3): Cross-manufacturer equivalent with TANTAMOUNT™ technology. ESR rated at 5.0 Ohm, suitable for general-purpose applications.

KEMET T491/T494 Series (T491A475M016AT, T494A475M016AT): Cross-manufacturer alternatives with specified lifetime rating of 2000 Hrs @ 125°C. T494A475M016AT provides lowest ESR at 3.0 Ohm among KEMET options.

Height variation exists between compact (0.047" / 1.20mm) and standard (0.071" / 1.80mm) profiles. PCB layout constraints determine acceptability of height differences.

Frequently Asked Questions (FAQ)

Q: Can TAJS475K016RNJ replace TAJS475M016RNJ directly?

A: Yes. TAJS475K016RNJ is a direct substitute with identical electrical and mechanical specifications except for tolerance upgrade from ±20% to ±10%. This represents improved capacitance accuracy with no performance degradation.

Q: What is the significance of ESR variation among substitute parts?

A: ESR (Equivalent Series Resistance) ranges from 2.0 Ohm to 5.0 Ohm across the substitute list. Lower ESR reduces impedance and heat generation in high-frequency or high-ripple-current applications. Selection depends on circuit requirements; all values are acceptable for general-purpose tantalum capacitor applications.

Q: Are there height restrictions when substituting parts?

A: The original TAJS475M016RNJ has a seated height of 0.047" (1.20mm). Most substitutes measure 0.071" (1.80mm). Verify PCB clearance and component placement constraints before selecting taller alternatives.

Q: Can cross-manufacturer parts (Vishay, KEMET) replace KYOCERA AVX parts?

A: Yes, provided all electrical parameters (capacitance, voltage, tolerance, ESR range) and mechanical specifications (package, mounting type, operating temperature) match. All listed cross-manufacturer parts meet these criteria and maintain ROHS3 compliance.

Q: What packaging differences exist among substitutes?

A: TAJS475M016RNJ and TAJS475K016RNJ are supplied in Tape & Reel (TR). TAJA475M016RNJ, TPSA475M016R2000, and T491A475M016AT use Cut Tape (CT) & Digi-Reel®. TCA1C475M8R, 293D475X0016A2TE3, and T494A475M016AT use Tape & Reel. Packaging selection affects procurement and assembly processes but does not impact electrical performance.

Q: Is MSL 1 (Unlimited) maintained across all substitutes?

A: Yes. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level, matching the original part specification.
