Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T95R226M050CSAS is determined by strict equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 22 µF (exact match required)
• Voltage Rating: 50 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 to 125°C (exact match required)
• Physical Dimensions: 0.283" L x 0.236" W, Height 0.150" max (exact match required)

Allowable Variation Parameters:

• Tolerance: May vary (±20% to ±10%)
• ESR: May vary within acceptable limits (390 mOhm to 300 mOhm)
• Packaging Format: May vary (Tape & Reel to Cut Tape & Digi-Reel®)
• RoHS Compliance: May differ (RoHS3 Compliant to RoHS non-compliant)

The T95R226K050LSAL qualifies as a parametric equivalent because it maintains all mandatory matching parameters while offering improved tolerance (±10% versus ±20%) and lower ESR (300 mOhm versus 390 mOhm), making it suitable for applications where tighter capacitance control and reduced impedance are beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R226M050CSAS and T95R226K050LSAL are active production parts from Vishay Sprague's TANTAMOUNT™ T95 series, ensuring long-term availability and consistent manufacturing quality.

T95R226M050CSAS Selection Criteria:

• Applications requiring RoHS3 compliance for regulated markets or end-use restrictions
• Designs where ±20% capacitance tolerance is acceptable
• Systems where higher ESR (390 mOhm) does not impact performance

T95R226K050LSAL Selection Criteria:

• Applications where tighter capacitance tolerance (±10%) improves circuit performance
• Designs benefiting from lower ESR (300 mOhm) for reduced impedance and improved transient response
• Procurement scenarios where RoHS non-compliance does not conflict with application requirements
• Availability of higher inventory levels (1,000,100 pcs versus 906 pcs)

Both parts maintain identical electrical ratings (22 µF, 50 V), physical dimensions, operating temperature range, and moisture sensitivity classification, ensuring direct functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can T95R226K050LSAL be used as a direct replacement for T95R226M050CSAS?

A: Yes, the T95R226K050LSAL is a direct functional replacement. Both parts share identical capacitance (22 µF), voltage rating (50 V), package (2824), physical dimensions, and operating temperature range. The substitute offers improved tolerance (±10% versus ±20%) and lower ESR (300 mOhm versus 390 mOhm). The primary difference is RoHS compliance status and packaging format.

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

A: Tolerance defines the allowable deviation from the nominal 22 µF capacitance value. The T95R226M050CSAS allows deviation from 17.6 µF to 26.4 µF, while the T95R226K050LSAL allows deviation from 19.8 µF to 24.2 µF. Applications requiring precise capacitance values benefit from the tighter ±10% tolerance of the substitute part.

Q: What does ESR difference (390 mOhm versus 300 mOhm) mean for circuit performance?

A: ESR (Equivalent Series Resistance) represents the internal resistance of the capacitor. Lower ESR reduces impedance and improves transient response, particularly in high-frequency filtering and power delivery applications. The T95R226K050LSAL's 300 mOhm ESR provides superior performance compared to the main part's 390 mOhm ESR.

Q: Are there packaging format differences between these parts?

A: Yes. The T95R226M050CSAS is supplied in Tape & Reel (TR) format, while the T95R226K050LSAL is available in Cut Tape (CT) and Digi-Reel® formats. Both formats are standard for surface mount assembly; selection depends on manufacturing equipment and volume requirements.

Q: What is the significance of RoHS compliance difference?

A: The T95R226M050CSAS is RoHS3 compliant, meeting regulatory requirements for restricted hazardous substances in regulated markets. The T95R226K050LSAL is RoHS non-compliant. Selection depends on end-use market requirements and regulatory obligations.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes, both parts are rated MSL 2A (4 Weeks), indicating identical moisture sensitivity and requiring the same handling and storage protocols during manufacturing and assembly.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, both parts are mechanically and electrically interchangeable in circuit designs. No PCB layout modifications or design changes are required. The substitute part's improved tolerance and lower ESR may enhance circuit performance without design revision.
