T95R157M020CSSS Equivalent & Substitute Parts

Part Overview

The T95R157M020CSSS 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T95R157M020CSSS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 20 V (exact match required)
• Package / Case: 2824 (7260 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Conformal Coated (exact match required)

Allowable Variation Parameters:

• Tolerance: May vary (±20% to ±10%)
• ESR: May vary within acceptable operating limits
• RoHS Compliance: May differ based on application requirements

The substitute part T95R157K020LSAL meets all mandatory matching criteria while offering improved tolerance specification (±10% versus ±20%) and reduced ESR (75 mOhm versus 140 mOhm). Both parts share identical capacitance, voltage rating, package configuration, and conformal coating specification.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R157M020CSSS and T95R157K020LSAL are active products from Vishay Sprague's TANTAMOUNT™ T95 series. The primary distinction between these parts is tolerance specification and ESR performance.

The T95R157M020CSSS offers ±20% tolerance with 140 mOhm ESR and maintains RoHS3 compliance. This configuration is suitable for applications where standard tolerance and ESR specifications are acceptable.

The T95R157K020LSAL provides tighter tolerance (±10%) and lower ESR (75 mOhm), offering improved performance characteristics. However, this part is RoHS non-compliant, which may restrict its use in applications requiring RoHS certification or regulatory compliance.

Selection between these parts should be based on specific application requirements regarding tolerance precision, ESR constraints, and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can T95R157K020LSAL replace T95R157M020CSSS in all applications?

A: Both parts share identical capacitance (150 µF), voltage rating (20 V), package configuration (2824), and conformal coating specification. The substitute offers improved tolerance and lower ESR. However, the substitute is RoHS non-compliant, which may disqualify it for applications requiring RoHS certification.

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

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal 150 µF value. The ±20% specification allows deviation from 120 µF to 180 µF, while ±10% restricts deviation to 135 µF to 165 µF. Applications requiring tighter capacitance control should specify the ±10% tolerance part.

Q: Does the ESR difference affect circuit performance?

A: ESR (Equivalent Series Resistance) influences ripple current handling, voltage drop, and thermal characteristics. The T95R157K020LSAL with 75 mOhm ESR provides lower impedance compared to the T95R157M020CSSS at 140 mOhm. Applications sensitive to ESR performance should evaluate this parameter against specific circuit requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2824 (7260 Metric) package with identical dimensions: 0.283" L x 0.236" W (7.20mm x 6.00mm) and maximum seated height of 0.150" (3.80mm). PCB layout and assembly processes remain unchanged.

Q: What is the impact of RoHS compliance status?

A: The T95R157M020CSSS is RoHS3 compliant, while T95R157K020LSAL is RoHS non-compliant. Applications subject to RoHS regulations, industry standards, or customer requirements must use the compliant part. Non-compliant parts may be restricted from certain markets or applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
