1812WA151MAT1A\SB Equivalent & Substitute Parts

Part Overview

The 1812WA151MAT1A\SB is a 150 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 2500V (2.5kV) operation with C0G/NP0 temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package format is designed for high-voltage general-purpose applications requiring stable capacitance across the 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 and substitute parts are identified to provide design flexibility, inventory alternatives, and performance optimization options for circuit implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812WA151MAT1A\SB is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 150 pF (exact match required)
• Temperature coefficient: C0G/NP0 (ensures stable performance across operating temperature range)
• Package format: 1812 (4532 Metric) surface mount configuration
• Mounting type: Surface mount MLCC technology
• Operating temperature range: -55°C to 125°C minimum

Secondary Compatibility Parameters:

• Voltage rating: Equal to or greater than 2500V
• Tolerance: ±20% or tighter
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or equivalent

The substitute part C4532C0G3F151K160KA from TDK Corporation meets all primary substitution criteria with enhanced voltage rating (3000V) and improved tolerance (±10%), making it a direct functional upgrade while maintaining identical package footprint and thermal characteristics.

Engineering Selection Recommendations

The C4532C0G3F151K160KA from TDK Corporation is a qualified substitute for the 1812WA151MAT1A\SB based on the following engineering factors:

Electrical Compatibility: Both parts maintain identical capacitance (150 pF) and temperature coefficient (C0G/NP0), ensuring equivalent circuit performance. The TDK substitute provides enhanced voltage margin with 3000V rating versus the original 2500V specification, and tighter tolerance (±10% versus ±20%), offering improved performance headroom for high-voltage applications.

Package and Mechanical Compatibility: Both components utilize the 1812 (4532 Metric) surface mount package format with identical width (0.126" / 3.20mm) and compatible length dimensions (0.181" versus 0.177"). The thickness difference (0.057" versus 0.071") is within typical PCB assembly tolerances for surface mount placement and reflow processes.

Regulatory and Compliance Status: Both parts maintain active product status, ROHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring equivalent handling, storage, and assembly requirements. Both are classified under identical HTSUS code (8532.24.0020) and ECCN (EAR99).

Inventory and Availability: The TDK substitute demonstrates significantly higher inventory availability (24,949 pieces versus 1,115 pieces), providing supply chain advantages for production volumes and long-term sourcing stability.

Frequently Asked Questions (FAQ)

Q: Can the C4532C0G3F151K160KA be used as a direct replacement for the 1812WA151MAT1A\SB?

A: Yes. Both parts share identical capacitance (150 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 1812 (4532 Metric) package format. The TDK substitute provides enhanced voltage rating (3000V versus 2500V) and tighter tolerance (±10% versus ±20%), making it functionally compatible and electrically superior for the same circuit application.

Q: Are there any physical compatibility concerns with the substitute part?

A: Physical dimensions are compatible for standard PCB assembly. The substitute has slightly reduced length (0.177" versus 0.181") and increased thickness (0.071" versus 0.057"), both within acceptable tolerances for 1812 package footprints. No PCB layout modifications are required.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: capacitance value (150 pF exact), temperature coefficient (C0G/NP0), package format (1812 / 4532 Metric), mounting type (surface mount MLCC), and operating temperature range (-55°C to 125°C). Voltage rating must equal or exceed 2500V, and tolerance must be ±20% or tighter.

Q: Does the substitute part require different handling or storage procedures?

A: No. Both parts maintain identical MSL 1 (Unlimited) moisture sensitivity rating and ROHS3 compliance status, requiring identical handling, storage, and assembly procedures.

Q: What is the advantage of using the TDK substitute over the original KYOCERA AVX part?

A: The TDK substitute offers three engineering advantages: higher voltage rating (3000V provides 20% additional margin), tighter capacitance tolerance (±10% versus ±20% for improved circuit precision), and significantly higher inventory availability for production continuity.
