Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 22201C155MAT1A is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1.5 µF
• Package / Case: 2220 (5750 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±10% or ±20% (tighter tolerance acceptable)
• Voltage - Rated: 100V or higher (higher voltage acceptable)
• Temperature Coefficient: X7R or X7T (both acceptable for general purpose applications)
• Thickness: Variation acceptable within mechanical constraints

Substitute parts are grouped into three categories based on specification alignment:

Direct Equivalent: C5750X7R2A155M230KA matches all critical parameters with identical 1.5 µF ±20% 100V X7R specifications.

Upgrade Option: C5750X7R2A155K230KM provides improved tolerance (±10%) while maintaining 100V rating and X7R coefficient, suitable for applications requiring tighter capacitance control.

Higher Voltage Alternative: C5750X7T2E155K200KA and C5750X7T2E155M200KA offer 250V rated voltage with X7T temperature coefficient, providing enhanced voltage margin for applications with potential overvoltage conditions.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Specification-Identical): C5750X7R2A155M230KA from TDK Corporation provides direct functional equivalence to the 22201C155MAT1A. Both parts share identical electrical specifications (1.5 µF ±20% 100V X7R) and mechanical compatibility. However, note that this substitute is marked "Not For New Designs," indicating it may have limited long-term availability. The reduced thickness (0.098" vs. 0.130") provides additional PCB layout flexibility.

For New Designs with Improved Tolerance: C5750X7R2A155K230KM offers tighter capacitance tolerance (±10% vs. ±20%) while maintaining 100V rating and X7R temperature coefficient. This part is also marked "Not For New Designs" but provides enhanced precision for applications requiring stricter capacitance control. Thickness reduction to 0.098" is compatible with standard PCB assembly processes.

For Applications Requiring Voltage Margin: C5750X7T2E155K200KA is the manufacturer-recommended substitute with active product status. This part provides 250V rated voltage (2.5× the original specification) with ±10% tolerance and X7T temperature coefficient. The higher voltage rating accommodates transient overvoltage conditions and provides design margin. Thickness of 0.087" is the most compact option. This part is actively produced and recommended for new designs.

C5750X7T2E155M200KA offers the same 250V voltage advantage with ±20% tolerance matching the original specification. This part is marked "Not For New Designs" but provides equivalent voltage margin with familiar tolerance characteristics.

Product Status Consideration: For new product designs, C5750X7T2E155K200KA is the preferred selection due to its active product status, higher voltage rating, and improved tolerance. For legacy system maintenance or direct replacement scenarios, C5750X7R2A155M230KA provides specification-identical substitution.

Frequently Asked Questions (FAQ)

Q: Can C5750X7T2E155K200KA be used as a direct replacement for 22201C155MAT1A?

A: Yes, C5750X7T2E155K200KA is electrically and mechanically compatible. The 250V rating is a superset of the 100V requirement, and X7T temperature coefficient is acceptable for general purpose applications. The ±10% tolerance is tighter than the original ±20%, providing improved precision. Physical dimensions and mounting type are identical.

Q: What is the difference between X7R and X7T temperature coefficients?

A: Both X7R and X7T are temperature coefficient classifications for ceramic capacitors. X7R specifies ±15% capacitance change over -55°C to 125°C. X7T specifies ±22% capacitance change over the same range. For general purpose applications, both are acceptable. X7R provides slightly better temperature stability.

Q: Why do some substitute parts have "Not For New Designs" status?

A: This designation indicates the manufacturer is phasing out the part or has limited production capacity. While these parts remain available and fully functional, they are not recommended for new product development. For new designs, select parts with "Active" product status such as C5750X7T2E155K200KA.

Q: Are the thickness differences between substitute parts significant?

A: The main part has 0.130" (3.30mm) thickness, while substitutes range from 0.087" to 0.098". Thinner parts provide additional PCB layout flexibility and may improve thermal performance. All thicknesses are compatible with standard surface mount assembly equipment. Verify PCB design clearances if space constraints exist.

Q: Can I use a ±10% tolerance part where ±20% is specified?

A: Yes. Tighter tolerance is always acceptable as a substitute. A ±10% part meets all requirements of a ±20% specification. Use ±10% parts when improved capacitance accuracy is beneficial for circuit performance.

Q: What is the significance of higher voltage rating in substitute parts?

A: A 250V-rated capacitor can safely operate at 100V with additional voltage margin. This margin protects against transient overvoltage events and provides design safety. Higher voltage rating does not negatively affect performance at lower operating voltages.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original part's environmental certifications.
