Substitute Part Grouping Explanation

Substitution eligibility for the TAJC336K020SNJ is determined by strict equivalence across the following parameters:

• Capacitance value: 33 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 20 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The substitute part 293D336X9020C2TE3 meets all mandatory electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance) are within acceptable engineering tolerances for general purpose applications and do not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the TAJC336K020SNJ and 293D336X9020C2TE3 are Active product status components with identical electrical ratings and mechanical compatibility. Selection between these parts should be based on:

• Availability and lead time requirements
• Supply chain preferences and established vendor relationships
• ESR performance requirements (293D336X9020C2TE3 offers lower ESR at 1 Ohm versus 1.5 Ohm)
• Regulatory compliance verification (both are ROHS3 Compliant and REACH Unaffected)

Both components are suitable for direct substitution in applications requiring 33 µF, 20 V molded tantalum capacitors in 2312 package form factor.

Frequently Asked Questions (FAQ)

Q: Can the 293D336X9020C2TE3 be used as a direct replacement for the TAJC336K020SNJ?

A: Yes. Both parts share identical capacitance (33 µF), tolerance (±10%), voltage rating (20 V), package (2312), and operating temperature range (-55°C ~ 125°C). Physical dimensions and mounting characteristics are equivalent.

Q: What is the significance of the ESR difference between these parts?

A: The TAJC336K020SNJ has an ESR of 1.5 Ohm @ 100kHz, while the 293D336X9020C2TE3 has an ESR of 1 Ohm. For general purpose applications, both values are acceptable. Lower ESR may provide marginal benefits in high-frequency filtering or low-impedance circuits, but this difference does not prevent substitution.

Q: Are there any height or dimensional concerns when substituting?

A: No. Both parts have identical length and width (0.236" x 0.126" / 6.00mm x 3.20mm). Maximum seated heights differ by 0.01mm (2.80mm versus 2.79mm), which is negligible for PCB assembly and does not affect compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TAJC336K020SNJ and 293D336X9020C2TE3 are ROHS3 Compliant, REACH Unaffected, and classified under the same HTSUS code (8532.21.0050). Moisture sensitivity level is MSL 1 (Unlimited) for both.

Q: What packaging formats are available for these parts?

A: Both parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
