1808CC393MAT1A Equivalent & Substitute Parts

Part Overview

The 1808CC393MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.039 µF with 630V operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 125°C). The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Substitute Part Grouping Explanation

The 1808CC393MAT1A has one identified substitute: 1808CC393KAT1A. This substitution is valid based on the following criteria:

Identical Parameters:

• Capacitance: 0.039 µF (exact match)
• Voltage Rating: 630V (exact match)
• Temperature Coefficient: X7R (exact match)
• Package / Case: 1808 (4520 Metric) (exact match)
• Mounting Type: Surface Mount, MLCC (exact match)
• Operating Temperature Range: -55°C to 125°C (exact match)
• Physical Dimensions: 0.181" L x 0.079" W x 0.087" Max Thickness (exact match)
• RoHS Status: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: MSL 1 (exact match)

Allowable Variation:

• Tolerance: ±20% (main part) vs. ±10% (substitute) — The substitute offers tighter tolerance, which is acceptable for general-purpose applications where the main part tolerance is sufficient.

Parameter Comparison

Engineering Selection Recommendations

The 1808CC393KAT1A is a direct functional equivalent to the 1808CC393MAT1A. Both parts are manufactured by KYOCERA AVX, maintain identical electrical specifications (0.039 µF, 630V, X7R), and are housed in the same 1808 package with matching physical dimensions and thermal characteristics.

The primary difference is tolerance specification: the substitute offers ±10% tolerance compared to the main part's ±20%. This represents an improvement in capacitance accuracy and does not introduce any compatibility issues for general-purpose applications.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory compliance. The substitute is available in Tape & Reel packaging, which may provide advantages for automated assembly processes compared to bulk packaging.

Selection between these parts should be based on packaging requirements (bulk vs. Tape & Reel) and tolerance specifications. The substitute is suitable for applications where tighter tolerance control is beneficial.

Frequently Asked Questions (FAQ)

Q: Can 1808CC393KAT1A replace 1808CC393MAT1A in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (0.039 µF), voltage rating (630V), temperature coefficient (X7R), package size (1808), and operating temperature range (-55°C to 125°C). The substitute's tighter tolerance (±10% vs. ±20%) does not create compatibility issues.

Q: What is the difference between these two parts?

A: The primary differences are tolerance specification (±10% vs. ±20%) and packaging format (Tape & Reel vs. bulk). Electrically and mechanically, the parts are equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both 1808CC393MAT1A and 1808CC393KAT1A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) rating.

Q: Does packaging format affect component performance?

A: No. Tape & Reel and bulk packaging formats contain identical components. Packaging selection is based on assembly process requirements and inventory management preferences.

Q: Can I use the substitute in high-temperature applications?

A: Yes. Both parts maintain the same operating temperature range of -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance across this range.

Q: Is the substitute suitable for 630V applications?

A: Yes. Both parts are rated for 630V operation and are suitable for high-voltage general-purpose applications.
