Key Parameters

Substitute Part Grouping Explanation

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

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

Substitute parts must maintain these parameters. Variations in tolerance, voltage rating, and temperature coefficient are permitted when the substitute part meets or exceeds the electrical requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified alternatives to the 1812GC221MAT1A based on compliance and product status criteria.

C1812C221MGRAC7800 (KEMET): This part maintains identical electrical specifications (220 pF, ±20%, 2000V, X7R) and is ROHS3 Compliant with MSL 1 rating. It is suitable for direct replacement in applications requiring equivalent performance.

C4532C0G3F221K200KA (TDK Corporation): This part exceeds the voltage rating (3000V vs. 2000V) and provides improved tolerance (±10% vs. ±20%). The C0G/NP0 temperature coefficient offers superior temperature stability compared to X7R. It is ROHS3 Compliant with MSL 1 rating and is suitable for applications where enhanced voltage margin or tighter tolerance is beneficial.

All three parts are Active status products with full regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can C1812C221MGRAC7800 be used as a direct replacement for 1812GC221MAT1A?

A: Yes. Both parts share identical capacitance (220 pF), tolerance (±20%), voltage rating (2000V), temperature coefficient (X7R), package (1812), and compliance certifications (ROHS3, MSL 1). They are mechanically and electrically interchangeable.

Q: What is the advantage of using C4532C0G3F221K200KA over the original part?

A: C4532C0G3F221K200KA provides a higher voltage rating (3000V vs. 2000V) and tighter tolerance (±10% vs. ±20%). The C0G/NP0 temperature coefficient provides superior capacitance stability across the operating temperature range compared to X7R. These characteristics make it suitable for applications requiring enhanced performance margins.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use the 1812 (4532 Metric) surface mount package. However, physical dimensions vary slightly: the KYOCERA AVX part has a maximum thickness of 1.80mm, the KEMET part 1.55mm, and the TDK part 2.20mm. Verify PCB layout clearance if space constraints exist.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control. All have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use C4532C0G3F221K200KA in a circuit designed for X7R capacitors?

A: C0G/NP0 temperature coefficient provides superior stability but different capacitance-temperature characteristics than X7R. Verify that the application does not depend on the specific X7R temperature behavior before substitution.
