1812HA181MATME Equivalent & Substitute Parts

Part Overview

The 1812HA181MATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 180 pF, rated for 3000V (3kV), and featuring C0G/NP0 temperature coefficient characteristics. This component is designed for general-purpose applications requiring stable capacitance across temperature variations and high-voltage performance. The part is currently in active production status with 928 units available in inventory.

Substitute parts become necessary when the original manufacturer experiences supply constraints, discontinuation, or when design requirements allow for compatible alternatives that meet or exceed the electrical and mechanical specifications of the primary component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812HA181MATME is permissible when the replacement component maintains the following critical parameters:

• Capacitance value of 180 pF
• Voltage rating of 3000V (3kV) or higher
• Temperature coefficient of C0G or NP0
• Operating temperature range of -55°C ~ 125°C or broader
• Package / Case designation of 1812 (4532 Metric)
• Surface Mount, MLCC mounting type
• ROHS3 compliance and MSL rating of 1

The substitute part C4532C0G3F181K160KA from TDK Corporation meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The C4532C0G3F181K160KA from TDK Corporation is a qualified substitute for the 1812HA181MATME. Both components are ROHS3 compliant and carry MSL rating of 1, ensuring compatibility with standard manufacturing and storage protocols.

The TDK substitute offers improved tolerance specification (±10% versus ±20%), which may provide enhanced capacitance stability in applications where tighter tolerance is beneficial. The physical dimensions are slightly smaller in length and thickness, which may provide layout advantages in space-constrained designs while maintaining full electrical equivalence.

The TDK part carries a Last Time Buy product status, indicating limited future availability. The KYOCERA AVX original part maintains active production status with current inventory of 928 units.

Frequently Asked Questions (FAQ)

Q: Can the C4532C0G3F181K160KA replace the 1812HA181MATME in all applications?

A: Yes, the C4532C0G3F181K160KA meets all critical electrical and mechanical parameters required for direct substitution. Both components share identical capacitance, voltage rating, temperature coefficient, and operating temperature range. The substitute features improved tolerance and is housed in the same 1812 (4532 Metric) package.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the acceptable deviation of actual capacitance from the nominal 180 pF value. The TDK substitute with ±10% tolerance provides tighter capacitance control, resulting in more predictable circuit performance. The original KYOCERA AVX part with ±20% tolerance remains suitable for applications where this wider tolerance is acceptable.

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

A: The TDK substitute is slightly smaller in length (4.50mm versus 4.60mm) and thickness (1.80mm versus 2.20mm). These minor dimensional variations are within standard PCB design tolerances and do not affect footprint compatibility for the 1812 (4532 Metric) package designation.

Q: Do both parts meet the same compliance standards?

A: Yes, both the 1812HA181MATME and C4532C0G3F181K160KA are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited moisture sensitivity level). Both components meet identical regulatory and environmental requirements.

Q: What is the inventory status for each part?

A: The original KYOCERA AVX part (1812HA181MATME) is in active production with 928 units currently in stock. The TDK substitute (C4532C0G3F181K160KA) carries Last Time Buy status with 2948 units available, indicating this is the final production run before discontinuation.
