Frequently Asked Questions (FAQ)

Q: Can the Vishay Sprague 293D335X96R3A2TE3 directly replace the TE Connectivity 1879062-9 without circuit modification?

A: Yes. The 293D335X96R3A2TE3 matches all primary equivalence criteria: 3.3 µF capacitance, ±10% tolerance, 6.3 V voltage rating, 1206 package, and surface mount configuration. ESR of 6.3 Ohm is within acceptable tolerance of the original 6 Ohm specification. No circuit modification is required.

Q: What is the difference between TAJA335K006RNJ and TAJS335K006RNJ?

A: Both parts provide 3.3 µF at 6.3 V in 1206 package with ±10% tolerance and Active product status. The primary difference is ESR: TAJA335K006RNJ has 7 Ohm ESR, while TAJS335K006RNJ has 9 Ohm ESR. Additionally, TAJS335K006RNJ uses manufacturer size code S with reduced seated height of 0.047" versus 0.071" for TAJA335K006RNJ. Selection depends on ESR requirements and available mounting clearance.

Q: Can I use a 10 V rated part (T491A335K010AT) in place of the 6.3 V original component?

A: Yes. Higher voltage-rated capacitors function as drop-in replacements in circuits designed for lower voltage ratings. The T491A335K010AT maintains 3.3 µF capacitance, ±10% tolerance, 6 Ohm ESR, and 1206 package. The 10 V rating provides additional voltage margin without affecting circuit operation. This upgrade substitution is electrically compatible.

Q: What is the advantage of the KEMET T499A335K016ATE6K0 over the T491A335K010AT?

A: The T499A335K016ATE6K0 extends operating temperature range to -55°C to 175°C (versus -55°C to 125°C for T491A335K010AT) and carries AEC-Q200 automotive qualification. Both parts provide 3.3 µF capacitance, ±10% tolerance, and 6 Ohm ESR in 1206 package. The T499A335K016ATE6K0 is specified for automotive applications and high-temperature environments requiring 2000 Hrs @ 175°C lifetime rating.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status. The original TE Connectivity 1879062-9 is REACH unaffected, and all substitute parts maintain REACH unaffected status. All parts are classified as EAR99 for export purposes.

Q: What packaging options are available for the substitute parts?

A: Substitute parts are available in Tape & Reel (TR) packaging for automated assembly and standard packaging. The Vishay Sprague 293D335X96R3A2TE3, KYOCERA AVX TAJA335K006RNJ, TAJS335K006RNJ, and KEMET parts are available in Tape & Reel. The KYOCERA AVX TAJA335K006S and TAJS335K006SNJ are available in standard packaging. Packaging selection depends on production requirements and handling procedures.

Q: Does the reduced height of TAJS335K006RNJ (0.047") versus the original (0.071") affect compatibility?

A: The reduced seated height of TAJS335K006RNJ requires verification of available mounting clearance in the target application. If the circuit board layout or component placement constraints allow only 0.071" height, the TAJS335K006RNJ will not fit. Mechanical clearance must be confirmed before selection. Alternative parts with standard 0.071" height include TAJA335K006RNJ, 293D335X96R3A2TE3, and all KEMET parts.

Q: Which substitute part offers the best ESR performance?

A: The Vishay Sprague 293D335X9020A2TE3 provides the lowest ESR at 5.9 Ohm. The original TE Connectivity 1879062-9 and most substitute parts specify 6 Ohm ESR. The KYOCERA AVX TAJA335K006RNJ and TAJA335K006S provide 7 Ohm ESR, while TAJS335K006RNJ and TAJS335K006SNJ provide 9 Ohm ESR. ESR selection depends on circuit filtering and ripple current requirements.

Q: Can I use the KYOCERA AVX F931E335KAA (25 V rating) in a 6.3 V circuit?

A: Yes. The F931E335KAA is a valid upgrade substitute with 25 V rating, 3.3 µF capacitance, ±10% tolerance, 6 Ohm ESR, and 1206 package. Higher voltage-rated capacitors operate correctly in lower voltage circuits. The 25 V rating provides maximum voltage margin and is suitable for applications requiring extended voltage derating or future design modifications.
