TAJS104M035RNJ Equivalent & Substitute Parts

Part Overview

The TAJS104M035RNJ is a 0.1 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 35 V with ±20% tolerance 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 package footprint and rated voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

• Capacitance: 0.1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 35 V (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The identified substitute parts meet all these criteria. Variations in ESR (Equivalent Series Resistance) and physical height are permitted within the same package classification, as these do not affect functional interchangeability in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and are ROHS3 compliant with REACH Unaffected designation, confirming regulatory equivalence. The 293D104X0035A2TE3 and T491A104M035AT both feature reduced ESR at 20 Ohm compared to the primary part's 24 Ohm specification, which represents an improvement in performance characteristics. The substitute parts exhibit increased seated height (0.071" versus 0.047"), which must be verified against PCB layout constraints and clearance requirements in the target application. All parts are classified as general-purpose tantalum capacitors with unlimited moisture sensitivity rating, suitable for equivalent circuit applications.

Frequently Asked Questions (FAQ)

Q: Can 293D104X0035A2TE3 be used as a direct replacement for TAJS104M035RNJ?

A: Yes. Both parts share identical capacitance (0.1 µF), tolerance (±20%), voltage rating (35 V), package (1206), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected). The primary difference is seated height (0.071" versus 0.047"), which must be confirmed compatible with PCB design.

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

A: ESR (Equivalent Series Resistance) affects high-frequency performance and ripple current handling. The substitute parts feature lower ESR (20 Ohm) compared to the primary part (24 Ohm), which is functionally equivalent or superior for general-purpose applications. This difference does not prevent substitution.

Q: Are there packaging differences between these parts?

A: The primary part is supplied in Tape & Reel (TR) format. The 293D104X0035A2TE3 is supplied in Cut Tape (CT) & Digi-Reel® format, while T491A104M035AT is supplied in Tape & Reel (TR). Packaging format does not affect component functionality but may impact procurement and assembly processes.

Q: Does the height difference affect PCB compatibility?

A: The substitute parts have a maximum seated height of 0.071" (1.80mm) compared to the primary part's 0.047" (1.20mm). This 0.024" (0.60mm) increase must be evaluated against PCB clearance requirements, component spacing, and enclosure constraints in the specific application.

Q: Are all three parts suitable for the same temperature range applications?

A: Yes. All three parts operate across the identical temperature range of -55°C ~ 125°C. The T491A104M035AT specifies a lifetime rating of 2000 hours at 125°C, providing additional reliability data for high-temperature applications.
