Niobium Oxide Capacitors Procurement Notes

This component is officially listed as obsolete and no longer manufactured by KYOCERA AVX. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific lot date code and storage conditions due to the part's discontinued status. Ensure that any available units meet RoHS3 compliance requirements before integration into new designs.

Niobium Oxide Capacitors Selection Notes

Engineers replacing this obsolete part should evaluate alternatives based on the required 330 µF capacitance, 6.3 V rating, and 2917 footprint. Consider niobium oxide or polymer tantalum capacitors from the same manufacturer that offer similar ESR and temperature performance. Verify that substitute components match the leakage current limits and physical dimensions to ensure compatibility with existing PCB layouts and thermal management strategies.

Niobium Oxide Capacitors Part Context

The NOJE337M006RWJ belongs to the OxiCap NOJ series, which represents KYOCERA AVX's niobium oxide capacitor line. This series is designed to provide high capacitance in small packages while maintaining safety standards. The product is part of Kyocera's broader portfolio of passive components, serving markets such as telecommunications, industrial automation, and consumer electronics where reliable energy storage is critical.

Niobium Oxide Capacitors Replacement Considerations

The TAJE337M006RNJ is a confirmed substitute part number from KYOCERA AVX. While it shares the same 330 µF, 6.3 V, and 2917 package specifications, it is a solid tantalum capacitor with different electrical characteristics, including a higher ESR of 400 mOhms and a wider operating temperature range up to 125°C. Designers must verify if these differences impact their specific application requirements.
