Substitute Part Grouping Explanation

Substitution eligibility for the T95R157K020LSAS is determined by strict adherence to the following parameters:

• Capacitance value: 150 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 20 V (exact match required)
• Type: Conformal Coated (exact match required)
• Package / Case: 2824 (7260 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Physical dimensions and height (exact match required)
• Moisture Sensitivity Level: 2A (4 Weeks) (exact match required)

The T95R157K020LSAL qualifies as a parametric equivalent because it maintains all critical electrical and mechanical specifications. The primary distinction is the ESR (Equivalent Series Resistance) value, which differs from the main part but remains within acceptable operational parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R157K020LSAS and T95R157K020LSAL are active production components with COTS qualification and high reliability ratings. Selection between these parts should be based on application-specific requirements for ESR performance. The T95R157K020LSAL exhibits lower ESR (75 mOhm) compared to the T95R157K020LSAS (140 mOhm), which may provide advantages in applications sensitive to impedance characteristics. Both parts maintain identical compliance status, thermal performance, and physical specifications. Inventory availability should also be considered in component selection decisions.

Frequently Asked Questions (FAQ)

Q: Can T95R157K020LSAL be used as a direct replacement for T95R157K020LSAS?

A: Yes. Both parts maintain identical capacitance (150 µF), voltage rating (20 V), tolerance (±10%), package (2824), and operating temperature range (-55°C ~ 125°C). The ESR difference does not prevent substitution in applications where the lower ESR of the T95R157K020LSAL is acceptable.

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

A: ESR (Equivalent Series Resistance) affects impedance characteristics at high frequencies. The T95R157K020LSAL has lower ESR (75 mOhm) compared to T95R157K020LSAS (140 mOhm). Applications requiring lower impedance or reduced ripple current dissipation may benefit from the lower ESR variant.

Q: Are the physical dimensions identical?

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).

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts are rated MSL 2A (4 Weeks), requiring identical handling and storage protocols.

Q: Are there any compliance differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant), ECCN (EAR99), and HTSUS (8532.21.0050) classifications.
