Substitute Part Grouping Explanation

Substitution eligibility for the T95R157M020CSAL is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance: 150 µF (exact match required)
• Voltage - Rated: 20 V (exact match required)
• Package / Case: 2824 (7260 Metric) (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 75 mOhm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Physical Dimensions: 0.283" L x 0.236" W, Height 0.150" max (exact match required)

Allowable Variation Parameter:

• Tolerance: ±20% (main part) to ±10% (substitute part) — tighter tolerance is acceptable as a substitute

The substitute part T95R157K020LSAL meets all critical parameters with an improved tolerance specification of ±10%, making it a valid parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The T95R157K020LSAL serves as a direct parametric equivalent to the T95R157M020CSAL. Both components are Active status products from the same manufacturer and series, with identical electrical and mechanical specifications. The substitute part features a tighter capacitance tolerance of ±10% compared to the main part's ±20%, which provides improved precision without compromising compatibility.

Selection between these parts should be based on compliance requirements and inventory availability. The main part (T95R157M020CSAL) carries RoHS3 compliance certification, while the substitute part (T95R157K020LSAL) is RoHS non-compliant. Applications requiring RoHS3 compliance must use the main part. For applications without RoHS compliance mandates, either part is electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can T95R157K020LSAL replace T95R157M020CSAL in my circuit?

A: Yes. Both parts are identical in capacitance (150 µF), voltage rating (20 V), ESR (75 mOhm), package (2824), and operating temperature range (-55°C to 125°C). The substitute has a tighter tolerance (±10% vs ±20%), which is acceptable for substitution. Verify RoHS compliance requirements for your application before selection.

Q: What is the difference between these two parts?

A: The primary differences are capacitance tolerance (±20% vs ±10%) and RoHS compliance status (RoHS3 compliant vs non-compliant). All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

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

Q: Does the tighter tolerance of the substitute part affect circuit performance?

A: The ±10% tolerance of T95R157K020LSAL is tighter than the ±20% tolerance of T95R157M020CSAL. This provides improved capacitance accuracy and may enhance circuit performance in applications sensitive to capacitance variation. No negative performance impact results from using the tighter tolerance part.

Q: What is the MSL rating and why does it matter?

A: Both parts carry an MSL rating of 2A (4 Weeks), indicating they can be exposed to moisture for up to 4 weeks at specified humidity levels before soldering. This rating applies equally to both parts and affects storage and handling procedures prior to assembly.
