1808WC150MAT1A Equivalent & Substitute Parts

Part Overview

The 1808WC150MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 15 pF and rated voltage of 2500V (2.5kV). This surface-mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient and is designed for general-purpose applications requiring high-voltage performance. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory availability, lead time considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

The substitute part C4520C0G3F150K110KA from TDK Corporation qualifies as an equivalent substitute based on the following critical parameters:

Matching Parameters:

• Capacitance: 15 pF (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Package / Case: 1808 (4520 Metric) (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)

Allowable Variations:

• Voltage - Rated: 3000V (3kV) vs. 2500V (2.5kV) — The substitute part has a higher rated voltage, which is acceptable for applications designed for 2500V operation
• Tolerance: ±10% vs. ±20% — The substitute part has tighter tolerance, which is acceptable
• Temperature Coefficient: C0G, NP0 vs. X7R — Both are suitable for general-purpose high-voltage applications with comparable temperature stability across the operating range
• Physical Dimensions: Slight variations in length (0.177" vs. 0.181") and thickness (0.051" vs. 0.071") remain within the 1808 package classification and are compatible with standard PCB layouts

Parameter Comparison

Engineering Selection Recommendations

Both the 1808WC150MAT1A and C4520C0G3F150K110KA are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for current and future regulatory requirements. The TDK substitute part offers higher voltage rating and tighter capacitance tolerance, providing additional design margin for high-voltage applications. The physical dimensions remain compatible with 1808 package footprints. Selection between these parts should be based on availability, lead time, packaging format (the substitute is available in Tape & Reel), and specific application voltage and tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can the C4520C0G3F150K110KA replace the 1808WC150MAT1A in my circuit?

A: Yes. Both parts share identical capacitance (15 pF), operating temperature range (-55°C ~ 125°C), package classification (1808/4520 Metric), and compliance certifications. The substitute has higher voltage rating (3kV vs. 2.5kV) and tighter tolerance (±10% vs. ±20%), making it suitable for applications designed for the original part.

Q: What are the physical compatibility considerations?

A: Both parts use the 1808 (4520 Metric) surface-mount package. The substitute is slightly smaller in length (4.50mm vs. 4.60mm) and thickness (1.30mm vs. 1.80mm), which is compatible with standard PCB layouts designed for 1808 components.

Q: Are there differences in temperature coefficient performance?

A: The original part uses X7R temperature coefficient, while the substitute uses C0G (NP0). Both provide stable capacitance across the -55°C ~ 125°C operating range suitable for general-purpose high-voltage applications.

Q: What packaging formats are available?

A: The 1808WC150MAT1A is available in standard packaging. The C4520C0G3F150K110KA substitute is available in Tape & Reel (TR) format, which is standard for high-volume production environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1808WC150MAT1A and C4520C0G3F150K110KA are ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.
