Substitute Part Grouping Explanation

Substitution eligibility for the T95R157K020CSSS is determined by strict equivalence across the following parameters:

• Capacitance: 150 µF (exact match required)
• Tolerance: ±10% (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)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The substitute part T95R157K020LSAL meets all mandatory electrical and mechanical parameters. The primary difference between the main part and the substitute is the Equivalent Series Resistance (ESR) specification, which is a performance characteristic that does not affect functional substitutability in applications where the rated capacitance, voltage, and package form factor are the controlling design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R157K020CSSS and T95R157K020LSAL are active products from Vishay Sprague and share identical electrical and mechanical specifications across all critical design parameters. Selection between these parts should be based on regulatory compliance requirements and application constraints.

The T95R157K020CSSS carries ROHS3 compliance certification, making it the appropriate choice for applications subject to RoHS regulations or customer specifications requiring RoHS compliance.

The T95R157K020LSAL is RoHS non-compliant and should be selected only in applications where RoHS compliance is not a requirement. This part offers a lower ESR specification (75 mOhm versus 140 mOhm), which may provide performance advantages in applications sensitive to series resistance characteristics.

Both parts are functionally interchangeable from a circuit design perspective when the primary design constraints are capacitance value, voltage rating, package form factor, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can T95R157K020LSAL be used as a direct replacement for T95R157K020CSSS?

A: Both parts are electrically and mechanically equivalent across all mandatory design parameters: 150 µF capacitance, ±10% tolerance, 20 V rating, 2824 package, and -55°C to 125°C operating range. Direct substitution is possible from a functional standpoint. However, RoHS compliance status differs between the parts. Verify that your application or customer requirements do not mandate RoHS compliance before selecting the substitute.

Q: What is the significance of the ESR difference between these parts?

A: The main part specifies 140 mOhm ESR while the substitute specifies 75 mOhm ESR. ESR affects ripple current handling, thermal performance, and frequency response characteristics. Applications with stringent ESR requirements should specify the appropriate part number. For general-purpose capacitance applications, both ESR values are within acceptable ranges for the 150 µF, 20 V rating class.

Q: Are the physical dimensions identical?

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 mechanical clearance requirements are identical.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry a Moisture Sensitivity Level (MSL) rating of 2A with a 4-week floor life. Standard moisture control procedures during storage, handling, and assembly are required.

Q: Which part should I specify for a new design?

A: For new designs, specify T95R157K020CSSS if RoHS3 compliance is required. If RoHS compliance is not a design constraint and lower ESR is beneficial, T95R157K020LSAL is an alternative. Both parts are active products with established supply chains.
