T95R157M020EZAS Equivalent & Substitute Parts

Part Overview

The T95R157M020EZAS is a 150 µF conformal coated tantalum capacitor manufactured by Vishay Sprague, rated for 20 V operation in a 2824 (7260 Metric) surface mount package. This component is part of the TANTAMOUNT™ T95 series and maintains active product status. Tantalum capacitors of this specification are essential in applications requiring high capacitance density, stable performance across temperature ranges, and reliable operation in demanding environments. Alternative models may be required due to inventory constraints, specific tolerance requirements, or ESR performance optimization for particular circuit applications.

Substitute Part Grouping Explanation

Substitution eligibility for the T95R157M020EZAS is determined by strict adherence to the following critical parameters:

• Capacitance value must remain 150 µF
• Voltage rating must be 20 V or higher
• Package / Case must be 2824 (7260 Metric) for mechanical and electrical compatibility
• Conformal coating type must be maintained
• Operating temperature range must encompass -55°C ~ 125°C
• Surface mount mounting type must be preserved
• Moisture sensitivity level must be 2A or better

The substitute part T95R157K020LSAL meets all substitution criteria. The primary difference is tolerance specification (±10% versus ±20%) and ESR performance (75 mOhm versus 140 mOhm), both of which represent improvements or equivalent performance characteristics within the same product family and package specification.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R157M020EZAS and T95R157K020LSAL are active products from Vishay Sprague with identical regulatory classifications (RoHS non-compliant, ECCN EAR99, HTSUS 8532.21.0050). Selection between these parts should be based on application-specific requirements:

The T95R157K020LSAL offers tighter tolerance (±10% versus ±20%) and lower ESR (75 mOhm versus 140 mOhm), making it suitable for applications where capacitance accuracy and low impedance are critical performance factors. The T95R157M020EZAS remains appropriate for applications where the broader tolerance and higher ESR are acceptable within circuit design margins.

Both components share identical mechanical compatibility, thermal operating range, and moisture sensitivity classification, ensuring direct substitution at the board assembly level without design modification.

Frequently Asked Questions (FAQ)

Q: Can T95R157K020LSAL be used as a direct replacement for T95R157M020EZAS?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (20 V), package (2824), conformal coating type, operating temperature range (-55°C ~ 125°C), and physical dimensions. The substitute offers improved tolerance and lower ESR.

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

A: Tolerance specifies the allowable deviation from the nominal 150 µF capacitance value. The ±10% tolerance of T95R157K020LSAL provides tighter capacitance accuracy, beneficial in precision filtering and timing applications. The ±20% tolerance of T95R157M020EZAS is acceptable in applications with broader design margins.

Q: How does ESR affect circuit performance?

A: Equivalent Series Resistance (ESR) represents the resistive losses within the capacitor. Lower ESR (75 mOhm in T95R157K020LSAL) reduces voltage ripple and heat generation, particularly important in high-frequency switching and power delivery applications. Higher ESR (140 mOhm in T95R157M020EZAS) is acceptable in general-purpose filtering applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components measure 0.283" L x 0.236" W (7.20mm x 6.00mm) with a maximum seated height of 0.150" (3.80mm), ensuring identical PCB footprint compatibility.

Q: What is the Moisture Sensitivity Level (MSL) requirement?

A: Both parts carry MSL 2A (4 Weeks), indicating they require controlled storage conditions and have a 4-week floor life after moisture exposure. Identical MSL classification ensures equivalent handling and storage requirements.

Q: Are there any compliance or regulatory differences?

A: No. Both parts share identical RoHS status (non-compliant), ECCN (EAR99), and HTSUS (8532.21.0050) classifications, indicating equivalent regulatory treatment for export and compliance purposes.
