Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJS334M035RNJ are qualified based on the following criteria:

• Identical capacitance value: 0.33 µF
• Identical tolerance: ±20%
• Identical rated voltage: 35 V
• Identical package: 1206 (3216 Metric)
• Identical mounting type: Surface Mount
• Identical operating temperature range: -55°C ~ 125°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

Variations in ESR (Equivalent Series Resistance) and physical height are permissible within the same package classification, as these do not affect footprint compatibility or primary electrical function in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TAJS334M035RNJ, TAJA334M035RNJ, and 293D334X0035A2TE3—meet the core electrical and mechanical requirements for direct substitution. Selection should be based on:

• Availability and inventory levels
• Preferred manufacturer qualification within your supply chain
• Physical height constraints in your PCB assembly (TAJS334M035RNJ at 1.20mm maximum height versus TAJA334M035RNJ and 293D334X0035A2TE3 at 1.80mm maximum height)
• ESR performance requirements (293D334X0035A2TE3 offers 13 Ohm ESR versus 15 Ohm for KYOCERA AVX variants)

All parts carry Active product status, ROHS3 compliance, and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can TAJA334M035RNJ replace TAJS334M035RNJ directly?

A: Yes. Both are KYOCERA AVX molded tantalum capacitors with identical electrical specifications (0.33 µF, ±20%, 35 V). The primary difference is physical height: TAJS334M035RNJ is 1.20mm maximum, while TAJA334M035RNJ is 1.80mm maximum. Verify PCB clearance before substitution.

Q: Is the Vishay Sprague 293D334X0035A2TE3 compatible with TAJS334M035RNJ?

A: Yes. The 293D334X0035A2TE3 meets all electrical and mechanical requirements: 0.33 µF capacitance, ±20% tolerance, 35 V rating, 1206 package, and identical operating temperature range. ESR is 13 Ohm versus 15 Ohm in the KYOCERA AVX parts. Physical height is 1.80mm maximum.

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

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The 293D334X0035A2TE3 at 13 Ohm provides lower ESR than the KYOCERA AVX variants at 15 Ohm. For general-purpose applications, both values are acceptable. High-frequency or high-ripple-current circuits may benefit from the lower ESR option.

Q: Are all three parts RoHS compliant?

A: Yes. TAJS334M035RNJ, TAJA334M035RNJ, and 293D334X0035A2TE3 are all ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

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

A: Both TAJ and TAJA are KYOCERA AVX molded tantalum capacitor series. The TAJA334M035RNJ is listed as a manufacturer-recommended substitute for TAJS334M035RNJ, indicating functional equivalence within KYOCERA AVX product lines.
