Substitute Part Grouping Explanation

Substitution for the TAJS225M006SNJ is determined by strict equivalence in the following parameters:

• Capacitance value: 2.2 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±20% (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 Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

Variations in ESR (Equivalent Series Resistance) and manufacturer size code do not disqualify substitution when all primary electrical and mechanical parameters are identical. All identified substitutes maintain full compatibility with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TAJS225M006SNJ, TAJS225M006RNJ, and TAJA225M006RNJ—are Active status components manufactured by KYOCERA AVX and maintain ROHS3 compliance and MSL 1 certification. Selection between these parts is based on application-specific requirements regarding ESR performance and physical height constraints.

TAJS225M006SNJ and TAJS225M006RNJ are electrically and mechanically identical, with both featuring 18 Ohm ESR and 0.047" (1.20mm) maximum seated height. These parts are direct functional equivalents.

TAJA225M006RNJ offers reduced ESR at 9 Ohm, which may provide performance benefits in applications sensitive to impedance characteristics. However, this part features increased maximum seated height of 0.071" (1.80mm), which must be evaluated against PCB layout and assembly clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can TAJS225M006RNJ be used as a direct replacement for TAJS225M006SNJ?

A: Yes. Both parts are identical in capacitance (2.2 µF), voltage rating (6.3 V), tolerance (±20%), package (1206), ESR (18 Ohm), and physical dimensions. They are functionally equivalent.

Q: What is the difference between TAJA225M006RNJ and the other two parts?

A: TAJA225M006RNJ differs in two parameters: ESR is reduced to 9 Ohm (versus 18 Ohm), and maximum seated height is 0.071" (1.80mm) versus 0.047" (1.20mm). All other electrical and mechanical specifications remain identical.

Q: Does the height difference of TAJA225M006RNJ affect compatibility?

A: Height difference must be evaluated against specific PCB design constraints. The increased height of 0.071" (1.80mm) may impact assembly clearance or component stacking. Verify PCB layout requirements before selection.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—TAJS225M006SNJ, TAJS225M006RNJ, and TAJA225M006RNJ—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for low-ESR applications?

A: TAJA225M006RNJ provides the lowest ESR at 9 Ohm. Selection requires confirmation that the increased seated height of 0.071" (1.80mm) is compatible with PCB assembly specifications.
