1812WC151KAT1A\SB Equivalent & Substitute Parts

Part Overview

The 1812WC151KAT1A\SB is a 150 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 2500V (2.5kV) operation with X7R temperature coefficient characteristics. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are identified to provide design flexibility, inventory alternatives, or when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812WC151KAT1A\SB is determined by the following critical parameters:

• Capacitance Value: 150 pF (exact match required)
• Tolerance: ±10% (must match or be tighter)
• Package / Case: 1812 (4532 Metric) (physical compatibility requirement)
• Mounting Type: Surface Mount, MLCC (assembly compatibility)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)
• Voltage Rating: Minimum 2500V (equal or higher acceptable)
• Temperature Coefficient: X7R or equivalent (C0G/NP0 acceptable as superior alternative)
• Compliance: ROHS3 and REACH requirements

The identified substitute part C4532C0G3F151K160KA from TDK Corporation meets all substitution criteria. This part maintains identical capacitance, tolerance, package dimensions, and operating temperature specifications while offering a higher voltage rating (3000V) and superior temperature stability through C0G/NP0 temperature coefficient.

Parameter Comparison

Engineering Selection Recommendations

The C4532C0G3F151K160KA substitute part is functionally equivalent and directly interchangeable with the 1812WC151KAT1A\SB in applications requiring 150 pF capacitance at 2500V or lower. Both parts maintain active production status and full compliance with ROHS3 and REACH regulations. The substitute offers enhanced voltage margin (3000V rating versus 2500V) and superior temperature stability through C0G/NP0 temperature coefficient, making it suitable for applications with stricter performance requirements. Physical dimensions are compatible with standard 1812 (4532 Metric) footprints, with negligible length variation (0.1mm difference) that does not impact PCB layout or assembly processes. Both parts carry MSL 1 rating, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can the C4532C0G3F151K160KA be used as a direct replacement for 1812WC151KAT1A\SB?

A: Yes. Both parts share identical capacitance (150 pF), tolerance (±10%), package (1812/4532 Metric), operating temperature range (-55°C to 125°C), and mounting type (Surface Mount, MLCC). The substitute meets or exceeds all electrical and mechanical requirements.

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

A: X7R provides ±15% capacitance variation across the operating temperature range. C0G/NP0 provides superior stability with minimal capacitance change across temperature. For the 150 pF value, C0G/NP0 offers tighter tolerance performance, making it suitable for precision applications.

Q: Does the higher voltage rating (3000V vs 2500V) affect compatibility?

A: No. Higher voltage rating is a beneficial characteristic that does not impact compatibility. The substitute part can be used in any application rated for 2500V or lower without derating.

Q: Are there physical footprint differences between these parts?

A: Both parts use the 1812 (4532 Metric) package with identical thickness (0.071" / 1.80mm). Length differs by 0.1mm (4.60mm vs 4.50mm), which is within standard PCB layout tolerances and does not require design modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating, ensuring equivalent regulatory and environmental compliance.
