The TAJB106K006RNJ: This is a molded tantalum capacitor from the TAJ series, rated 10 µF at 6.3 V with ±10% tolerance. The 3 Ohm ESR is typical for this size code B in the TAJ family — higher than a ceramic MLCC of the same capacitance, so it runs warmer under ripple current and needs derating on a 5 V rail to stay within the voltage rating. The 1411 (3528 Metric) case measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm.
The case is 1411 (3528 Metric), size code B. The land pattern follows the standard 3528 tantalum footprint: 3.50 mm x 2.80 mm body with a 2.10 mm seated height. Confirm the pad dimensions against the manufacturer's recommended land pattern in the TAJ series datasheet.
No official second-source or pin-compatible equivalent is listed by KYOCERA AVX for this specific TAJ series order code. Other tantalum capacitor manufacturers (Kemet, Vishay) offer 10 µF, 6.3 V, size B molded parts, but the ESR, ripple current rating, and case dimensions should be cross-checked against the BOM's derating requirements before substitution.
