1808GA101MAT3A Equivalent & Substitute Parts

Part Overview

The 1808GA101MAT3A is a 100 pF ceramic capacitor rated at 2000V (2kV) 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 ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, lead times are extended, or design requirements allow for upgraded electrical specifications while maintaining mechanical compatibility and functional performance in the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1808GA101MAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 100 pF (no deviation permitted)
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Voltage Rating: May be equal to or greater than 2000V
• Temperature Coefficient: C0G/NP0 or X7R acceptable for general-purpose applications
• Tolerance: May be ±20% or tighter (±10%)
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Two substitute parts meet these criteria with upgraded voltage ratings and improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active production components with full ROHS3 compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility with the original 1808GA101MAT3A.

C4520C0G3F101K200KA (TDK Corporation) maintains the C0G/NP0 temperature coefficient of the original part while providing a 50% voltage rating increase to 3000V and improved tolerance of ±10%. This part is suitable for applications where the original 2kV rating is adequate but tighter capacitance tolerance is beneficial. Dimensional variation is minimal (length 4.50mm vs. 4.60mm original).

C1808C101KHRAC7800 (KEMET) offers a 50% voltage rating increase to 3000V with ±10% tolerance and X7R temperature coefficient. The X7R specification provides broader temperature stability characteristics compared to C0G/NP0, with slightly increased thickness (1.75mm vs. 1.45mm original). This part is designated as manufacturer-recommended and includes low ESL features.

Both substitutes are mechanically compatible within the 1808 (4520 Metric) package footprint and support the full -55°C to 125°C operating temperature range. Selection between substitutes depends on whether C0G/NP0 temperature coefficient is required for the application or whether X7R performance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can C4520C0G3F101K200KA or C1808C101KHRAC7800 be used as direct replacements for 1808GA101MAT3A?

A: Yes, both parts are direct substitutes. All three components share identical capacitance (100 pF), package (1808/4520 Metric), mounting type (Surface Mount MLCC), and operating temperature range (-55°C to 125°C). The substitute parts provide equal or superior voltage ratings (3000V vs. 2000V) and equal or improved tolerance (±10% vs. ±20%).

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

A: C0G/NP0 provides stable capacitance across the operating temperature range with minimal variation. X7R allows greater capacitance variation across temperature but maintains acceptable performance for general-purpose applications. The original 1808GA101MAT3A uses C0G/NP0; the TDK substitute maintains this specification, while the KEMET substitute uses X7R.

Q: Are there physical size differences that affect PCB layout?

A: Minor dimensional variations exist. The TDK part is slightly shorter (4.50mm vs. 4.60mm), while the KEMET part is slightly longer (4.70mm vs. 4.60mm). Thickness varies: TDK 2.20mm, KEMET 1.75mm, original 1.45mm. These variations are within typical PCB design tolerances for 1808 package components and do not require layout modification.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, carry EAR99 ECCN classification, and have MSL 1 (unlimited) moisture sensitivity ratings. Regulatory and environmental compliance is equivalent across all three options.

Q: Which substitute should be selected if voltage derating is a design consideration?

A: Both substitutes provide 3000V ratings, offering 50% additional voltage margin compared to the 2000V original. This increased margin is beneficial for applications with voltage transients or where design safety factors require additional headroom. Selection between the two substitutes should be based on temperature coefficient requirements rather than voltage performance.
