Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJS336K004RNJ are qualified based on the following criteria:

• Capacitance Value: Must be 33 µF (±10% tolerance maintained)
• Voltage Rating: Must be rated for 4 V minimum
• Package / Case: Must be 1206 (3216 Metric) surface mount
• Component Type: Must be molded tantalum construction
• Operating Temperature: Must support -55°C ~ 125°C range
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The TAJA336K004RNJ qualifies as a substitute part under these parameters. Variations in ESR (Equivalent Series Resistance) and seated height are permissible within the mechanical envelope constraints of the 1206 package, provided all electrical and compliance specifications are maintained.

Parameter Comparison

Engineering Selection Recommendations

Both the TAJS336K004RNJ and TAJA336K004RNJ are Active product status components from KYOCERA AVX with full ROHS3 compliance and MSL 1 rating. Selection between these parts is based on application-specific ESR requirements and availability:

• TAJS336K004RNJ: Lower ESR (1.7 Ohm) suitable for applications requiring minimal impedance at operating frequencies
• TAJA336K004RNJ: Higher ESR (3 Ohm) acceptable for general purpose filtering and energy storage applications

Both parts maintain identical electrical performance for capacitance, voltage rating, tolerance, and temperature range. The seated height difference (1.20mm vs 1.80mm) remains within the 1206 package mechanical constraints and does not affect PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can TAJA336K004RNJ be used as a direct replacement for TAJS336K004RNJ?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (4 V), tolerance (±10%), package (1206), and operating temperature range (-55°C ~ 125°C). The ESR difference and seated height variation do not prevent direct substitution in general purpose applications.

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

A: ESR (Equivalent Series Resistance) affects impedance characteristics at high frequencies. The TAJS336K004RNJ (1.7 Ohm) provides lower impedance, while the TAJA336K004RNJ (3 Ohm) is suitable for standard filtering applications. Selection depends on circuit frequency response requirements.

Q: Are there any PCB layout considerations for the height difference?

A: The seated height difference (1.20mm vs 1.80mm) is within the 1206 package specification. Both parts fit the same footprint and do not require layout modifications. Verify clearance for any components or enclosure constraints in your specific design.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAJS336K004RNJ and TAJA336K004RNJ are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity). They meet identical environmental and regulatory requirements.

Q: What is the difference between the TAJ and TAJA series designations?

A: The series designation reflects internal KYOCERA AVX product line categorization. Both TAJ and TAJA series are molded tantalum capacitors with equivalent electrical specifications for this 33 µF, 4 V application.
