T95R157M020CSAS Equivalent & Substitute Parts

Part Overview

The T95R157M020CSAS is a 150 µF conformal coated tantalum capacitor rated for 20 V operation in a 2824 (7260 Metric) surface mount package. This component is manufactured by Vishay Sprague under the TANTAMOUNT™ T95 series and maintains active product status. Tantalum capacitors of this specification are used in applications requiring high reliability, compact form factors, and stable performance across extended temperature ranges. Alternative models may be required due to inventory constraints, specific tolerance requirements, or compliance considerations for particular applications.

Substitute Part Grouping Explanation

Substitution for the T95R157M020CSAS is determined by strict adherence to the following parameters:

Capacitance must remain 150 µF. Voltage rating must be 20 V or higher. Package and case must be 2824 (7260 Metric) to ensure mechanical and electrical compatibility. Mounting type must be surface mount. Type must be conformal coated tantalum. Operating temperature range must support -55°C to 125°C operation.

The substitute part T95R157K020LSAL meets these core requirements while introducing a variation in tolerance (±10% versus ±20%) and ESR (75 mOhm versus 140 mOhm). These differences represent tighter specifications that maintain functional compatibility while offering improved performance characteristics in specific applications.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R157M020CSAS and T95R157K020LSAL are active products from Vishay Sprague's TANTAMOUNT™ T95 series. The primary distinction lies in compliance status and electrical performance characteristics.

The T95R157M020CSAS carries RoHS3 compliance certification, making it suitable for applications subject to RoHS regulatory requirements. The T95R157K020LSAL is RoHS non-compliant and should be selected only for applications where RoHS compliance is not mandated.

The T95R157K020LSAL offers superior electrical performance through tighter tolerance (±10% versus ±20%) and lower ESR (75 mOhm versus 140 mOhm). These characteristics may be advantageous in applications requiring reduced ripple current handling or tighter capacitance stability. Selection between these parts should be based on regulatory compliance requirements and application-specific performance needs.

Frequently Asked Questions (FAQ)

Q: Can T95R157K020LSAL be used as a direct replacement for T95R157M020CSAS?

A: Both parts share identical capacitance (150 µF), voltage rating (20 V), package (2824), and operating temperature range (-55°C to 125°C). The T95R157K020LSAL features tighter tolerance and lower ESR, making it functionally compatible. However, the RoHS compliance difference must be evaluated against application requirements.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the acceptable deviation of actual capacitance from the nominal 150 µF value. The ±10% tolerance of T95R157K020LSAL provides tighter capacitance control, which may be critical in applications with strict circuit performance requirements. The ±20% tolerance of T95R157M020CSAS is acceptable for applications with broader tolerance margins.

Q: Does the ESR difference affect circuit performance?

A: ESR (Equivalent Series Resistance) impacts ripple current handling and voltage drop characteristics. The T95R157K020LSAL's lower ESR of 75 mOhm versus the T95R157M020CSAS's 140 mOhm results in reduced heat generation and improved high-frequency performance. Selection depends on application-specific ripple current and thermal requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2824 (7260 Metric) package with identical dimensions of 0.283" L x 0.236" W (7.20mm x 6.00mm) and maximum seated height of 0.150" (3.80mm). They are mechanically interchangeable on PCB layouts.

Q: What is the impact of RoHS compliance status on part selection?

A: RoHS3 compliance is mandatory for products sold into regulated markets, particularly in the European Union and similar jurisdictions. The T95R157M020CSAS meets RoHS3 requirements, while the T95R157K020LSAL does not. Application destination and regulatory requirements determine which part is appropriate.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the T95R157M020CSAS and T95R157K020LSAL carry MSL 2A (4 Weeks) rating, indicating identical moisture sensitivity and storage requirements.
