Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAJS155M010RNJ is determined by strict equivalence in the following parameters:

• Capacitance Value: 1.5 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 10 V (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Molded tantalum (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

The identified substitute part 293D155X0010A2TE3 (Vishay Sprague) meets all mandatory electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance) and physical height are permitted within the allowed design envelope for this capacitor category, provided all core parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TAJS155M010RNJ and 293D155X0010A2TE3 are Active product status components with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on:

• Availability: The 293D155X0010A2TE3 (Vishay Sprague) currently has higher inventory (2638 Pcs) compared to TAJS155M010RNJ (797 Pcs).
• ESR Characteristics: The 293D155X0010A2TE3 provides lower ESR (8 Ohm vs. 20 Ohm), which may be advantageous in applications sensitive to impedance or ripple current performance.
• Physical Height: The TAJS155M010RNJ has a lower seated height (1.20mm vs. 1.80mm), which may be critical in space-constrained PCB designs.
• Regulatory Compliance: Both parts meet REACH Unaffected and EAR99 ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can 293D155X0010A2TE3 be used as a direct replacement for TAJS155M010RNJ?

A: Yes. Both parts share identical electrical specifications (1.5 µF, ±20%, 10 V) and mechanical compatibility (1206 package, surface mount). The difference in ESR (8 Ohm vs. 20 Ohm) represents an improvement in performance characteristics and does not prevent substitution.

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

A: The TAJS155M010RNJ has a maximum seated height of 1.20mm, while the 293D155X0010A2TE3 is 1.80mm. In applications with tight vertical clearance constraints, the KYOCERA AVX part may be preferred. For most general purpose applications, both heights are acceptable within standard PCB assembly tolerances.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both parts are rated for -55°C ~ 125°C operation, meeting the same thermal specifications.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 indicates the lowest moisture sensitivity level. These components have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or assembly.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.
