Substitute Part Grouping Explanation

Substitution eligibility for the T95R157M020LSAS is determined by the following criteria:

• Identical capacitance value: 150 µF
• Identical voltage rating: 20 V
• Identical package: 2824 (7260 Metric)
• Identical mounting type: Surface Mount
• Identical type classification: Conformal Coated
• Identical operating temperature range: -55°C ~ 125°C
• Identical moisture sensitivity level: 2A (4 Weeks)

The T95R157K020LSAL qualifies as a parametric equivalent based on these core electrical and mechanical parameters. Variations in tolerance and ESR do not preclude substitution when circuit design permits such variations.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R157M020LSAS and T95R157K020LSAL are Active status components from the same manufacturer series. Selection between these parts depends on circuit-specific tolerance and ESR requirements:

The T95R157M020LSAS provides ±20% tolerance with 140 mOhm ESR and is suitable for applications where broader tolerance specifications are acceptable.

The T95R157K020LSAL provides tighter ±10% tolerance with lower 75 mOhm ESR, offering improved performance characteristics for circuits requiring reduced equivalent series resistance or stricter capacitance accuracy.

Both parts share identical compliance classifications (RoHS non-compliant, ECCN EAR99, HTSUS 8532.21.0050) and environmental ratings. Interchangeability is confirmed for applications where the specified tolerance and ESR parameters are compatible with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can T95R157K020LSAL replace T95R157M020LSAS in all applications?

A: Substitution is valid when circuit design permits ±10% tolerance and lower ESR operation. The substitute part offers improved tolerance accuracy and reduced series resistance compared to the main part.

Q: Are the physical dimensions identical between these parts?

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). PCB layout and assembly processes require no modification.

Q: What is the significance of the tolerance difference?

A: The main part specifies ±20% tolerance, while the substitute specifies ±10%. The tighter tolerance of the substitute part ensures capacitance values remain closer to the nominal 150 µF specification across the operating range.

Q: How does ESR affect circuit performance?

A: ESR (Equivalent Series Resistance) impacts ripple current handling and voltage drop characteristics. The substitute part's lower 75 mOhm ESR compared to the main part's 140 mOhm provides reduced impedance at operating frequencies.

Q: Are moisture sensitivity requirements the same?

A: Yes. Both parts are rated MSL 2A (4 Weeks), requiring identical moisture control and handling procedures during storage and assembly.

Q: Do these parts have different compliance or regulatory classifications?

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