The X case code matches the standard 2917 land pattern; no footprint adjustment needed. No official second source or pin-compatible cross listed. The TAJ series is widely stocked across independent channels; a same-series alternate with the same capacitance and voltage rating is a direct swap.","metaTitle":"TAJX337M004RNJ – KYOCERA AVX 330 µF Molded Tantalum Cap, 4 V","metaDescription":"Active KYOCERA AVX TAJ series molded tantalum capacitor. 330 µF, 4 V, ±20%, 300 mOhm ESR, -55 to +125 °C, 2917 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Specialty Capacitors"],"specifications":{"Mfr":"KYOCERA AVX","Type":"Molded","Series":"TAJ","Package":"Tape & Reel (TR)","Features":"General Purpose","Tolerance":"±20%","Capacitance":"330 µF","Failure Rate":"-","Lead Spacing":"-","Mounting Type":"Surface Mount","Package / Case":"2917 (7343 Metric)","Product Status":"Active","Voltage - Rated":"4 V","lifecycle_stage":"unknown","Lifetime @ Temp.":"-","Size / Dimension":"0.287\\\" L x 0.169\\\" W (7.30mm x 4.30mm)","Height - Seated (Max)":"0.059\\\" (1.50mm)","Operating Temperature":"-55°C ~ 125°C","Manufacturer Size Code":"X","ESR (Equivalent Series Resistance)":"300mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0144","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ce09bb895bbc5407352e9a690f57411c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy TAJX337M004RNJ and check current pricing?","answer":"This part is active and sourced through independent distribution.
