Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAJS156M010RNJ is determined by strict equivalence in the following parameters:

• Capacitance: 15 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage - Rated: 10 V (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The following parts meet all substitution criteria: TAJA156M010RNJ (KYOCERA AVX), TPSA156M010R1000 (KYOCERA AVX), and T491A156M010AT (KEMET).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—TAJA156M010RNJ, TPSA156M010R1000, and T491A156M010AT—maintain full electrical and mechanical equivalence to the TAJS156M010RNJ within the specified parameter set. All parts carry Active product status and ROHS3 compliance certification. Selection among these equivalents should be based on application-specific requirements not defined in the core substitution parameters, such as ESR performance characteristics, manufacturer availability, or design margin considerations for specific circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can TAJA156M010RNJ be used as a direct replacement for TAJS156M010RNJ?

A: Yes. Both parts share identical capacitance (15 µF), tolerance (±20%), voltage rating (10 V), package (1206), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, MSL 1). The primary difference is ESR (3.2 Ohm vs. 2 Ohm) and seated height (0.071" vs. 0.047"), which must be evaluated for specific circuit board layout constraints.

Q: What is the difference between TPSA156M010R1000 and TAJS156M010RNJ?

A: Both parts are electrically equivalent in capacitance, voltage, tolerance, and temperature range. TPSA156M010R1000 features lower ESR (1 Ohm vs. 2 Ohm) and belongs to the TPS series rather than the TAJ series. Seated height is 0.071" compared to 0.047" for the original part.

Q: Is T491A156M010AT from KEMET compatible with the TAJS156M010RNJ?

A: Yes. T491A156M010AT meets all core electrical and mechanical substitution criteria: 15 µF capacitance, ±20% tolerance, 10 V rating, 1206 package, and identical operating temperature range. It is ROHS3 compliant with MSL 1 rating. The part carries a specified lifetime rating of 2000 Hrs @ 125°C.

Q: Are there any package or footprint considerations when substituting these parts?

A: The TAJS156M010RNJ has a maximum seated height of 0.047" (1.20mm), while all three substitute parts have a maximum seated height of 0.071" (1.80mm). PCB layout and component clearance must accommodate this height difference. All parts maintain identical length (0.126") and width (0.063") dimensions.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. TAJS156M010RNJ and all substitute parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
