The TAJA476K006SNJV is a 47 µF ±10% rated 6.3 V molded tantalum capacitor from the KYOCERA AVX TAJ series, housed in a 1206 (3216 Metric) surface-mount package.
Temperature range and ESR profile
No direct pin-compatible second source is documented; the TAJ series is the OEM's own standard, so a BOM substitution would require a different series or manufacturer with the same 1206 footprint and ratings.
