1808WA101MATME Equivalent & Substitute Parts

Part Overview

The 1808WA101MATME is a 100 pF ceramic capacitor rated at 2500V (2.5kV) with C0G/NP0 temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part is currently active in production with 620 units in stock. Equivalent and substitute parts are identified based on matching or exceeding the core electrical and mechanical specifications while maintaining compatibility with the 1808 (4520 Metric) package footprint.

Substitute Part Grouping Explanation

Substitute parts for the 1808WA101MATME are qualified based on the following criteria:

Capacitance Match: 100 pF (exact match required)
Voltage Rating: Equal to or greater than 2500V
Package Compatibility: 1808 (4520 Metric) footprint
Mounting Type: Surface Mount, MLCC
Temperature Range: -55°C to 125°C minimum
Compliance: ROHS3 Compliant, REACH Unaffected

The identified substitutes meet or exceed these parameters. Temperature coefficient variations (C0G/NP0 vs. X7R) are noted as they affect frequency and temperature stability characteristics, though both are acceptable for general-purpose applications within the specified operating range.

Engineering Selection Recommendations

Both substitute parts exceed the electrical specifications of the 1808WA101MATME while maintaining full compatibility with the 1808 (4520 Metric) package footprint.

C4520C0G3F101K200KA (TDK Corporation) provides a direct upgrade with identical C0G/NP0 temperature coefficient, improved tolerance (±10% vs. ±20%), and higher voltage rating (3000V vs. 2500V). This part maintains the same thermal stability characteristics as the original. Inventory availability is 3400 units.

C1808C101KHRAC7800 (KEMET) offers the highest voltage rating (3000V) with improved tolerance (±10%) and the lowest profile thickness (0.069" vs. 0.087"). The X7R temperature coefficient provides broader temperature stability characteristics compared to C0G/NP0, though with slightly different frequency response. This part is manufacturer-recommended and has 2948 units in stock.

All three parts are ROHS3 compliant, REACH unaffected, and rated for MSL 1 (unlimited moisture sensitivity). Selection between substitutes depends on specific application requirements regarding temperature coefficient stability and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can C4520C0G3F101K200KA replace 1808WA101MATME directly?

A: Yes. Both parts share identical capacitance (100 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 1808 (4520 Metric) package footprint. The TDK part provides improved tolerance (±10% vs. ±20%) and higher voltage rating (3000V vs. 2500V).

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

A: C0G/NP0 provides near-zero capacitance change across the operating temperature range, ensuring stable performance in temperature-sensitive applications. X7R allows up to ±15% capacitance variation across temperature but offers broader voltage and frequency characteristics. Both are suitable for general-purpose applications within -55°C to 125°C.

Q: Are there physical size differences between these parts?

A: All three parts use the 1808 (4520 Metric) package with identical width (0.079" / 2.00mm). Length varies slightly: KYOCERA AVX 0.181" (4.60mm), TDK 0.177" (4.50mm), KEMET 0.185" (4.70mm). Thickness differs: KYOCERA AVX and TDK 0.087" (2.20mm), KEMET 0.069" (1.75mm). These variations are within standard 1808 package tolerances and compatible with standard PCB footprints.

Q: Which substitute part is recommended by the manufacturer?

A: KEMET C1808C101KHRAC7800 is designated as the manufacturer-recommended substitute, offering the lowest profile and highest voltage rating.

Q: Are all parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
