Equivalent & Substitute Parts for 1808GA331KATME

Part Overview

The 1808GA331KATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 330 pF, rated voltage of 2000V (2kV), and C0G/NP0 temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part is currently active and ROHS3 compliant. Equivalent and substitute parts are identified when they maintain the same capacitance value, tolerance, temperature coefficient, and package footprint while meeting or exceeding voltage ratings and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1808GA331KATME is determined by the following critical parameters:

• Capacitance Value: Must be 330 pF
• Tolerance: Must be ±10%
• Temperature Coefficient: Must be C0G or NP0
• Package / Case: Must be 1808 (4520 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Must be equal to or greater than 2000V (2kV)
• Operating Temperature Range: Must support -55°C ~ 125°C
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The substitute part VPDP302G331K1GV001E from Johanson Dielectrics Inc. qualifies as an upgrade substitute because it maintains all critical electrical and mechanical parameters while providing a higher voltage rating of 3000V (3kV), offering improved design margin for high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

The VPDP302G331K1GV001E from Johanson Dielectrics Inc. is a qualified upgrade substitute for the 1808GA331KATME. Both parts maintain identical electrical specifications for capacitance, tolerance, and temperature coefficient. The substitute part provides a higher voltage rating of 3000V (3kV) compared to the original 2000V (2kV), offering increased design margin for high-voltage applications. Physical dimensions are within acceptable tolerance for 1808 package footprints. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements. The substitute part is actively produced and available in high inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can VPDP302G331K1GV001E be used as a direct replacement for 1808GA331KATME?

A: Yes. Both parts share identical capacitance (330 pF), tolerance (±10%), temperature coefficient (C0G/NP0), package footprint (1808/4520 Metric), and operating temperature range (-55°C ~ 125°C). The substitute part has a higher voltage rating (3kV vs 2kV), making it suitable for direct substitution in applications designed for the original part.

Q: What are the physical compatibility considerations?

A: The substitute part dimensions (0.185" L x 0.080" W x 0.085" max thickness) are within acceptable tolerance of the original part (0.181" L x 0.079" W x 0.087" max thickness) for standard 1808 package footprints. Both parts use surface-mount technology with identical mounting requirements.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: What is the primary advantage of the substitute part?

A: The VPDP302G331K1GV001E provides a 50% higher voltage rating (3000V vs 2000V), offering improved design margin and reliability in high-voltage applications while maintaining all other electrical and mechanical specifications.

Q: Are there any application-specific considerations?

A: The original part is specified for general-purpose applications, while the substitute part is designated for SMPS (Switched-Mode Power Supply) filtering. The substitute part's higher voltage rating makes it suitable for both application categories.
