Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJS225M010SNJ are qualified based on the following criteria:

• Capacitance value: 2.2 µF (exact match required)
• Voltage rating: 10 V (exact match required)
• Tolerance: ±20% (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 compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Variations in ESR (Equivalent Series Resistance), manufacturer series designation, and packaging format (Tape & Reel vs. Cut Tape) do not disqualify substitution when all primary electrical and mechanical parameters align. Height-seated maximum and manufacturer size codes may vary within the 1206 package specification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original TAJS225M010SNJ. Selection among substitutes should be based on:

• ESR requirements: Lower ESR values (1.8 Ohm to 7 Ohm range) are available across KYOCERA AVX TPS, TC, and TAJ series, as well as KEMET T491 and T494 series, and Vishay Sprague 293D series.
• Packaging format availability: Tape & Reel format is standard across most substitutes; Cut Tape & Digi-Reel® format is available for TAJA225M010RNJ, T491A225M010AT.
• Height constraints: Original part height is 0.047" (1.20mm); substitute parts with 0.071" (1.80mm) seated height require PCB layout verification for clearance compatibility.
• Manufacturer preference: KYOCERA AVX, KEMET, and Vishay Sprague all provide qualified alternatives with identical electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can TAJS225M010SNJ be directly replaced with TAJA225M010RNJ?

A: Yes. Both parts share identical capacitance (2.2 µF), voltage rating (10 V), tolerance (±20%), package (1206), and operating temperature range (-55°C ~ 125°C). The primary difference is ESR (7 Ohm vs. 12 Ohm) and seated height (0.071" vs. 0.047"). Verify PCB clearance for the increased height before substitution.

Q: What is the difference between KYOCERA AVX TAJ, TC, and TPS series?

A: All three series meet the electrical specifications for this application. The primary distinction is ESR: TAJ series (12 Ohm), TC series (5.6 Ohm), and TPS series (1.8 Ohm). Selection depends on circuit requirements for equivalent series resistance performance.

Q: Are KEMET T491 and T494 series compatible with TAJS225M010SNJ?

A: Yes. Both KEMET series maintain the required 2.2 µF capacitance, 10 V rating, ±20% tolerance, 1206 package, and -55°C ~ 125°C operating range. ESR values differ (7 Ohm for T491A225M010AT, 6 Ohm for T494A225M010AT). Both are ROHS3 compliant with MSL 1 rating.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format is a logistics and handling consideration only. Electrical and mechanical specifications remain identical regardless of whether the part is supplied in Tape & Reel or Cut Tape & Digi-Reel® format.

Q: Can Vishay Sprague 293D225X0010A2TE3 replace TAJS225M010SNJ?

A: Yes. The Vishay part meets all primary electrical and mechanical requirements: 2.2 µF, 10 V, ±20% tolerance, 1206 package, -55°C ~ 125°C operating range, ROHS3 compliance, and MSL 1. ESR is 6.3 Ohm. Verify design compatibility with the 0.071" seated height.

Q: What should be verified before substituting parts with different ESR values?

A: ESR affects circuit performance in high-frequency applications and power dissipation characteristics. Review circuit schematics and performance requirements to confirm that the substitute part's ESR value is acceptable for the intended application. Lower ESR values generally provide improved high-frequency performance.
