Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original TAJS335K016RNJ. Selection among substitutes should be based on:

Packaging Format Compatibility: The TAJS335K016RNJ is supplied in Tape & Reel (TR) format. Direct format equivalents include TPSA335K016R3500, 293D335X9016A2TE3, T494A335K016AT, and TR3A335K016C3500. Parts supplied in Cut Tape (CT) & Digi-Reel® format (TAJA335K016RNJ, T491A335K016AT) require compatible handling equipment.

ESR Specification: The original part specifies 5 Ohm ESR. Parts with lower ESR values (4.6 Ohm: TPSA335K016R3500, TR3A335K016C3500; 4 Ohm: T494A335K016AT) provide improved performance characteristics and are electrically compatible.

Physical Height Constraints: The TAJS335K016RNJ has a maximum seated height of 1.20 mm. All substitute parts have a maximum seated height of 1.80 mm. PCB layout clearance must accommodate this dimensional difference.

Manufacturer Availability: KYOCERA AVX substitutes (TAJA335K016RNJ, TPSA335K016R3500) maintain original manufacturer continuity. Vishay Sprague (293D335X9016A2TE3, TR3A335K016C3500) and KEMET (T491A335K016AT, T494A335K016AT) alternatives provide cross-manufacturer options.

Frequently Asked Questions (FAQ)

Q: Can I substitute TAJS335K016RNJ with TAJA335K016RNJ?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (3.3 µF, 16 V, ±10%, 5 Ohm ESR). The primary difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) and seated height (1.20 mm vs. 1.80 mm). Verify PCB clearance for the increased height.

Q: What is the difference between 5 Ohm and 4.6 Ohm ESR substitutes?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. Lower ESR values (4.6 Ohm) provide superior performance in high-frequency applications. Both values are electrically compatible with the original 5 Ohm specification.

Q: Are cross-manufacturer substitutes (Vishay Sprague, KEMET) fully compatible?

A: Yes. All listed substitutes meet identical electrical specifications (3.3 µF, 16 V, ±10%, -55°C ~ 125°C) and package requirements (1206 / 3216 Metric). All are ROHS3 compliant with MSL 1 rating. Verify with your procurement and quality assurance processes for cross-manufacturer qualification.

Q: Does the seated height difference affect PCB assembly?

A: The TAJS335K016RNJ has a maximum seated height of 1.20 mm. All substitutes have a maximum seated height of 1.80 mm. Verify PCB layout clearance, solder reflow profiles, and component placement constraints before substitution.

Q: Can I use T494A335K016AT (4 Ohm ESR) instead of the original 5 Ohm part?

A: Yes. The 4 Ohm ESR is lower than the original 5 Ohm specification and provides improved electrical performance. All other parameters (capacitance, voltage, package, temperature range, tolerance) are identical.

Q: What is the inventory status of these substitutes?

A: Inventory levels vary by part number. TAJA335K016RNJ has the highest availability (55,100 pcs). Verify current stock with your supplier before design finalization.
