Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAJD156K020SNJ is determined by strict equivalence across the following parameters:

• Capacitance: 15 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 20 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Physical Dimensions: 0.287" L x 0.169" W, Height 0.122" max (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the original component.

Parameter Comparison

Engineering Selection Recommendations

All three components—TAJD156K020SNJ, 293D156X9020D2TE3, and T491D156K020AT—maintain Active product status and are ROHS3 compliant with REACH Unaffected designation. They are electrically and mechanically equivalent for direct substitution in 15 µF, 20 V, 2917 package applications.

The T491D156K020AT (KEMET) offers the lowest ESR specification at 1 Ohm and includes a defined lifetime rating of 2000 hours at 125°C. The 293D156X9020D2TE3 (Vishay Sprague) specifies 900 mOhm ESR. The TAJD156K020SNJ does not provide ESR specification in the available data. Selection between these parts should be based on supply chain availability, packaging preference (Tape & Reel versus Cut Tape & Digi-Reel), and application-specific ESR requirements.

Frequently Asked Questions (FAQ)

Q: Can T491D156K020AT replace TAJD156K020SNJ directly? A: Yes. Both components share identical electrical specifications (15 µF, ±10%, 20 V), package type (2917/7343 Metric), physical dimensions, and operating temperature range (-55°C ~ 125°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the substitute parts? A: The primary differences are manufacturer identity and ESR specification. T491D156K020AT specifies 1 Ohm ESR with 2000-hour lifetime at 125°C. 293D156X9020D2TE3 specifies 900 mOhm ESR. TAJD156K020SNJ does not provide ESR data. All three are mechanically and electrically equivalent for the stated 15 µF, 20 V application.

Q: Does packaging format affect substitution? A: Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) does not affect electrical or mechanical compatibility. Selection depends on assembly process requirements and supply chain logistics.

Q: Are all substitute parts RoHS compliant? A: Yes. TAJD156K020SNJ, 293D156X9020D2TE3, and T491D156K020AT are all ROHS3 compliant and REACH Unaffected.

Q: What is the moisture sensitivity level for these components? A: All three components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
