Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJS225K006RNJ are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Must Match):

• Capacitance: 2.2 µF
• Tolerance: ±10%
• Voltage Rating: 6.3 V
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount
• Size / Dimension: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts meet these criteria. Variations in ESR (Equivalent Series Resistance) and seated height are within acceptable design tolerances for general purpose tantalum capacitor applications and do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified equivalents for the TAJS225K006RNJ based on matching electrical specifications, mechanical package dimensions, and compliance certifications.

TAJA225K006RNJ (KYOCERA AVX): Same manufacturer as the main part. Offers lower ESR (9 Ohm vs. 18 Ohm) and higher inventory availability (7126 pcs). Seated height increases to 0.071" (1.80mm). Suitable for direct substitution where PCB layout accommodates the increased height.

293D225X96R3A2TE3 (Vishay Sprague): Lowest ESR specification at 7.6 Ohm. TANTAMOUNT™ series designation. Seated height 0.071" (1.80mm). Inventory availability 2733 pcs. Suitable for applications where reduced ESR provides performance benefits.

T491A225K006AT (KEMET): ESR specification 8 Ohm. Lifetime rating of 2000 Hrs @ 125°C provided. Seated height 0.071" (1.80mm). Inventory availability 1855 pcs. Suitable for applications requiring documented lifetime performance data.

All parts maintain ROHS3 compliance, MSL 1 rating, and -55°C ~ 125°C operating temperature range. Selection among substitutes depends on PCB layout constraints (seated height tolerance), ESR performance requirements, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TAJA225K006RNJ replace TAJS225K006RNJ directly on the PCB?

A: Yes, electrical specifications are identical. However, TAJA225K006RNJ has a maximum seated height of 0.071" (1.80mm) compared to TAJS225K006RNJ at 0.047" (1.20mm). Verify PCB layout clearance before substitution.

Q: What is the significance of ESR differences among the substitute parts?

A: ESR (Equivalent Series Resistance) values range from 7.6 Ohm to 18 Ohm across the part group. Lower ESR reduces heat generation and improves high-frequency performance. Selection depends on circuit requirements; all values are within acceptable ranges for general purpose applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TAJS225K006RNJ, TAJA225K006RNJ, 293D225X96R3A2TE3, and T491A225K006AT are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do substitute parts have the same capacitance tolerance?

A: Yes. All parts maintain ±10% capacitance tolerance at 2.2 µF nominal value.

Q: Which substitute offers the best availability?

A: TAJA225K006RNJ (KYOCERA AVX) has the highest inventory at 7126 pcs, followed by 293D225X96R3A2TE3 (Vishay Sprague) at 2733 pcs, and T491A225K006AT (KEMET) at 1855 pcs.

Q: Is lifetime rating data available for all parts?

A: T491A225K006AT specifies 2000 Hrs @ 125°C lifetime rating. TAJS225K006RNJ, TAJA225K006RNJ, and 293D225X96R3A2TE3 do not provide lifetime specifications in the available data.
