Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1812GC271MATME is determined by the following critical parameters:

• Capacitance Value: Must be 270 pF (exact match required)
• Package / Case: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Voltage Rating: Must be equal to or greater than 2000V (2kV)
• Temperature Coefficient: X7R or equivalent (C0G/NP0 acceptable for superior stability)
• Compliance: RoHS3 and REACH requirements must be maintained

The TDK Corporation C4532C0G3F271K230KA qualifies as a direct substitute based on matching capacitance, package dimensions, mounting type, and operating temperature range. The substitute offers enhanced voltage rating (3000V vs 2000V) and superior temperature coefficient stability (C0G/NP0 vs X7R), making it suitable for applications requiring higher voltage margins or tighter capacitance tolerance (±10% vs ±20%).

Parameter Comparison

Engineering Selection Recommendations

The TDK C4532C0G3F271K230KA is electrically and mechanically compatible with the KYOCERA AVX 1812GC271MATME for applications requiring 270 pF capacitance in 1812 package format. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly processes.

The substitute part provides higher voltage rating (3000V vs 2000V), which offers additional design margin in high-voltage applications. The C0G/NP0 temperature coefficient of the TDK part delivers superior capacitance stability across temperature extremes compared to the X7R coefficient of the original part. Tolerance improvement (±10% vs ±20%) may benefit applications with stringent capacitance specifications.

Physical dimensions are comparable with minor variations: the TDK part is slightly shorter in length (4.50mm vs 4.60mm) but thicker (2.50mm vs 1.80mm). These dimensional differences must be evaluated against PCB layout constraints and available board space.

The TDK part carries Last Time Buy status, indicating limited future availability. Procurement decisions should account for long-term supply requirements and inventory planning.

Frequently Asked Questions (FAQ)

Q: Can the TDK C4532C0G3F271K230KA directly replace the KYOCERA AVX 1812GC271MATME?

A: Yes, for applications requiring 270 pF capacitance in 1812 package format. Both parts are surface mount MLCCs with identical capacitance values, matching operating temperature ranges, and compatible compliance certifications. Verify that the higher voltage rating (3000V) and different temperature coefficient (C0G/NP0 vs X7R) align with your circuit requirements.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (3000V vs 2000V), temperature coefficient (C0G/NP0 vs X7R), tolerance (±10% vs ±20%), and physical thickness (2.50mm vs 1.80mm). The TDK part offers superior voltage margin and capacitance stability but requires verification of PCB space availability due to increased thickness.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. No compliance barriers exist for substitution. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard reflow soldering processes.

Q: Does the package dimension difference affect PCB layout?

A: The 1812 (4532 Metric) package designation is identical for both parts, ensuring footprint compatibility on PCB layouts. However, the thickness difference (1.80mm vs 2.50mm) must be considered for applications with height constraints or specific component stacking requirements.

Q: What is the significance of the Last Time Buy status for the TDK part?

A: Last Time Buy status indicates that TDK has announced end-of-life for the C4532C0G3F271K230KA. Future availability is limited. If long-term supply is required, procurement should be completed within the announced Last Time Buy window, or alternative sourcing strategies should be evaluated.
