1808HC101MAT1A Equivalent & Substitute Parts

Part Overview

The 1808HC101MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 100 pF with 3000V (3kV) operating voltage and X7R temperature coefficient. This component is designed for general-purpose applications requiring high-voltage performance in a compact surface-mount package. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the 1808HC101MAT1A is determined by strict equivalence across the following critical parameters:

• Capacitance value: 100 pF (exact match required)
• Voltage rating: 3000V minimum (equal or higher acceptable)
• Package / Case: 1808 (4520 Metric) form factor
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C ~ 125°C minimum
• Compliance certifications: RoHS3 and REACH status

The substitute part CC1808JKNPOEBN101 meets all mandatory electrical and mechanical parameters. While the temperature coefficient differs (C0G/NP0 versus X7R), both coefficients support the required operating temperature range and are suitable for general-purpose applications. The tolerance specification (±5% versus ±20%) represents an improvement in precision without affecting substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808HC101MAT1A and CC1808JKNPOEBN101 maintain Active product status with full regulatory compliance (RoHS3 and REACH). Selection between these parts should be based on:

• Availability and lead time requirements
• Tolerance specification needs (±5% precision available with substitute)
• PCB layout constraints (substitute offers reduced thickness: 1.80mm versus 2.20mm)
• Supplier qualification and procurement processes

The substitute part CC1808JKNPOEBN101 provides equivalent electrical performance with improved dimensional characteristics and tighter tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can CC1808JKNPOEBN101 directly replace 1808HC101MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (100 pF), voltage rating (3000V), operating temperature range (-55°C ~ 125°C), and 1808 package form factor. The substitute offers tighter tolerance (±5% versus ±20%) and reduced thickness, making it mechanically and electrically compatible.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance variation across the operating temperature range. C0G/NP0 provides superior stability with minimal variation. Both coefficients support the -55°C ~ 125°C operating range and are suitable for general-purpose applications.

Q: Are there dimensional compatibility concerns?

A: The substitute part is slightly smaller in length (4.50mm versus 4.60mm) and significantly thinner (1.80mm versus 2.20mm). These differences are within standard 1808 package tolerances and do not affect PCB footprint compatibility. Verify PCB layout clearances for height-sensitive applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings. Regulatory and environmental compliance is equivalent.

Q: What packaging formats are available?

A: The main part (1808HC101MAT1A) is available in standard packaging. The substitute (CC1808JKNPOEBN101) is supplied in Tape & Reel (TR) format, which is standard for high-volume surface-mount applications.
