Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC221MAT1A\SB is determined by the following critical parameters:

• Capacitance value: 220 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable parameter variations for substitution:

• Voltage - Rated: Equal to or greater than 2000V (2kV)
• Tolerance: ±20% or tighter (±10% acceptable)
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general purpose applications)

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the critical substitution criteria and maintain full compliance with regulatory requirements.

C1812C221MGRAC7800 (KEMET) is a direct functional equivalent with identical capacitance, tolerance, voltage rating, and temperature coefficient. This part features low ESL characteristics and is available in Tape & Reel packaging. All compliance certifications match the original specification.

C4532C0G3F221K200KA (TDK Corporation) provides enhanced voltage performance at 3000V (3kV), exceeding the 2000V requirement. The C0G/NP0 temperature coefficient offers superior temperature stability compared to X7R. Tolerance is tighter at ±10%. Physical dimensions vary slightly with increased thickness at 2.20mm maximum. This part is available in Cut Tape & Digi-Reel packaging and maintains full regulatory compliance.

All three parts are active products with current production status and adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can C4532C0G3F221K200KA be used as a direct replacement for 1812GC221MAT1A\SB?

A: Yes. The higher voltage rating (3kV vs 2kV) and superior temperature coefficient (C0G vs X7R) make it functionally compatible. The ±10% tolerance is tighter than the original ±20%, which is acceptable. Physical dimensions differ slightly; verify PCB layout clearance for the 2.20mm thickness.

Q: What is the difference between X7R and C0G temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides ±30 ppm/°C, resulting in minimal capacitance variation. Both are suitable for general purpose applications; C0G offers superior stability for precision circuits.

Q: Are there packaging differences between the substitute parts?

A: Yes. The original part uses standard packaging (not specified). C1812C221MGRAC7800 is supplied in Tape & Reel format. C4532C0G3F221K200KA is supplied in Cut Tape & Digi-Reel format. Verify your assembly process compatibility with the supplied packaging format.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and have MSL rating of 1 (Unlimited). Regulatory compliance is equivalent across all options.

Q: What is the inventory status for each part?

A: 1812GC221MAT1A\SB: 922 pieces in stock. C1812C221MGRAC7800: 2569 pieces in stock. C4532C0G3F221K200KA: 39968 pieces in stock.
