TAJS335K010RNJ Equivalent & Substitute Parts

Part Overview

The TAJS335K010RNJ is a 3.3 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 10 V operation in a 1206 (3216 Metric) surface mount package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same capacitance, voltage rating, tolerance, and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJS335K010RNJ are qualified based on the following criteria:

• Identical capacitance value: 3.3 µF
• Identical voltage rating: 10 V
• Identical tolerance: ±10%
• Identical package footprint: 1206 (3216 Metric)
• Identical mounting type: Surface Mount
• Identical operating temperature range: -55°C ~ 125°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical moisture sensitivity level: 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance), physical height, and packaging format (Tape & Reel vs. Cut Tape) do not disqualify substitution when the above criteria are met.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection between the main part and substitutes should be based on:

• Packaging format availability: TAJS335K010RNJ and T491A335K010AT are supplied in Tape & Reel format; TAJA335K010RNJ and 293D335X9010A2TE3 are supplied in Cut Tape & Digi-Reel format.
• ESR characteristics: The main part (TAJS335K010RNJ) has 8Ohm ESR. Substitute parts offer lower ESR values (5.5Ohm to 6Ohm), which may provide improved performance in noise-sensitive applications.
• Physical height: The main part has a maximum seated height of 0.047" (1.20mm). Substitute parts have a maximum seated height of 0.071" (1.80mm). PCB layout constraints must be verified before substitution.
• Inventory availability: T491A335K010AT (KEMET) has the highest inventory level at 33,987 pieces.

Frequently Asked Questions (FAQ)

Q: Can TAJA335K010RNJ be used as a direct replacement for TAJS335K010RNJ?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (3.3 µF, 10 V, ±10% tolerance). The primary difference is packaging format (Cut Tape vs. Tape & Reel) and physical height (0.071" vs. 0.047"). PCB layout must accommodate the increased height.

Q: What is the significance of ESR differences among substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and noise performance. The main part has 8Ohm ESR, while substitutes range from 5.5Ohm to 6Ohm. Lower ESR values provide improved performance in high-frequency applications but do not affect basic capacitance or voltage rating compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the main part TAJS335K010RNJ, are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Does the packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape & Digi-Reel formats are packaging and delivery methods only. Electrical performance is identical for parts with matching specifications.

Q: Can I substitute a part with higher ESR?

A: ESR is a provided specification. Parts with different ESR values are listed as substitutes because they maintain all core electrical parameters (capacitance, voltage, tolerance) and mechanical compatibility (package, footprint, height). Application requirements determine whether ESR differences are acceptable.
