TAJS225M020RNJ Equivalent & Substitute Parts

Part Overview

The TAJS225M020RNJ is a 2.2 µF molded tantalum capacitor rated at 20 V in a 1206 (3216 Metric) surface mount package, manufactured by KYOCERA AVX. This component is classified as Active product status and is designed for general purpose applications requiring stable capacitance performance across the operating temperature range of -55°C to 125°C. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAJS225M020RNJ are qualified based on the following critical parameters that determine functional equivalence:

• Capacitance value: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 20 V (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)
• Type: Molded Tantalum (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• MSL: 1 (Unlimited) (exact match required)

The identified substitute parts meet all these criteria. Variations in ESR (Equivalent Series Resistance) and seated height are within acceptable ranges for this product category and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TAJS225M020RNJ, TAJA225M020RNJ, and 293D225X0020A2TE3—are Active product status components with ROHS3 compliance and REACH Unaffected status, qualifying them for use in regulated applications. Selection between these parts should be based on availability, lead time, and inventory requirements rather than electrical performance differences, as all meet the specified electrical and mechanical parameters for this application.

Frequently Asked Questions (FAQ)

Q: Can TAJA225M020RNJ be used as a direct replacement for TAJS225M020RNJ?

A: Yes. Both parts share identical capacitance (2.2 µF), tolerance (±20%), voltage rating (20 V), package (1206), and operating temperature range (-55°C ~ 125°C). The difference in seated height (0.071" vs 0.047") and ESR (5.3 Ohm vs 4.5 Ohm) does not prevent substitution for general purpose applications.

Q: What is the difference between the KYOCERA AVX and Vishay Sprague options?

A: Both manufacturers provide molded tantalum capacitors with identical electrical specifications. The 293D225X0020A2TE3 from Vishay Sprague has a slightly higher ESR (5.9 Ohm) compared to the KYOCERA AVX parts, but all three meet the same functional requirements for this application.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three parts use the 1206 (3216 Metric) surface mount package with identical footprint dimensions (0.126" L x 0.063" W). Seated height variations (0.047" to 0.071") are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), making them suitable for identical application environments.
