1808SC151KATME Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808SC151KATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 150 pF capacitance with 1500V (1.5kV) voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1808SC151KATME is determined by the following critical parameters:

• Capacitance Value: Must be 150 pF ±10%
• Temperature Coefficient: Must be X7R for stable performance across the operating temperature range
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Must meet or exceed 1500V (1.5kV) minimum requirement
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The identified substitute part VPDP202W151K1GV001E from Johanson Dielectrics Inc. meets all substitution criteria with an upgraded voltage rating of 2000V (2kV), providing enhanced performance margin while maintaining identical capacitance, tolerance, temperature coefficient, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808SC151KATME and VPDP202W151K1GV001E are active production parts with ROHS3 compliance and unlimited moisture sensitivity rating. The substitute part VPDP202W151K1GV001E provides a higher voltage rating (2000V vs. 1500V) while maintaining all other electrical and mechanical specifications. Selection between these parts depends on circuit voltage requirements and supply availability. The VPDP202W151K1GV001E offers increased design margin for applications operating near the 1500V threshold.

Frequently Asked Questions (FAQ)

Q: Can VPDP202W151K1GV001E replace 1808SC151KATME in all applications?

A: Yes, provided the circuit board layout and thermal management accommodate the slightly larger thickness (2.16mm vs. 1.80mm maximum). The substitute part maintains identical capacitance, tolerance, temperature coefficient, and package footprint (1808 / 4520 Metric).

Q: What is the difference in physical dimensions between these parts?

A: The main difference is thickness: 1808SC151KATME has a maximum thickness of 0.071" (1.80mm), while VPDP202W151K1GV001E has a maximum thickness of 0.085" (2.16mm). Length and width dimensions are comparable (4.60mm vs. 4.70mm length; 2.00mm vs. 2.03mm width).

Q: Are both parts suitable for high-voltage applications?

A: Yes. The 1808SC151KATME is rated for 1500V, and the substitute VPDP202W151K1GV001E is rated for 2000V. Both are classified as high-voltage ceramic capacitors suitable for SMPS filtering and general-purpose high-voltage circuits.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts ROHS3 compliant?

A: Yes. Both 1808SC151KATME and VPDP202W151K1GV001E are ROHS3 compliant and REACH unaffected.
