TAJS104K035RNJ Equivalent & Substitute Parts

Part Overview

The TAJS104K035RNJ is a 0.1 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 35 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 TAJS104K035RNJ are qualified based on the following criteria:

• Identical capacitance value: 0.1 µF
• Identical voltage rating: 35 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, ensuring long-term availability and regulatory conformance. The TAJA104K035RNJ from KYOCERA AVX is the manufacturer-recommended substitute, offering identical electrical specifications with higher inventory availability. The 293D104X9035A2TE3 (Vishay Sprague) and T491A104K035AT (KEMET) are cross-manufacturer alternatives that meet all core electrical and mechanical requirements. Selection among these substitutes should be based on supply chain availability, packaging format preference (Tape & Reel vs. Cut Tape), and ESR tolerance requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can TAJA104K035RNJ replace TAJS104K035RNJ directly?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (0.1 µF, 35 V, ±10% tolerance) and package footprint (1206). The primary difference is packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel) and physical height (0.071" vs. 0.047"). Verify PCB clearance if height is a constraint.

Q: What is the significance of ESR differences between substitutes?

A: The TAJS104K035RNJ and TAJA104K035RNJ specify 24 Ohm ESR, while the 293D104X9035A2TE3 and T491A104K035AT specify 20 Ohm ESR. Lower ESR reduces heat generation and improves high-frequency performance. Both values are acceptable for general-purpose applications; verify ESR requirements for ripple current or noise-sensitive circuits.

Q: Are all substitutes compatible with the same PCB footprint?

A: Yes. All parts use the 1206 (3216 Metric) package with identical length (0.126") and width (0.063"). Physical height varies between 0.047" and 0.071"; confirm PCB clearance constraints before substitution.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). All carry ECCN EAR99 and HTSUS 8532.21.0050 classifications.

Q: Which substitute offers the best availability?

A: The T491A104K035AT (KEMET) and TAJA104K035RNJ (KYOCERA AVX) both show high inventory levels (105,400 and 105,100 units respectively), providing reliable supply chain options.
