1808AC153MATME Equivalent & Substitute Parts

Part Overview

The 1808AC153MATME is a 0.015 µF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. 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 and substitute parts are identified to address inventory availability, packaging preferences, or tolerance requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808AC153MATME is determined by the following critical parameters:

• Capacitance Value: Must be 0.015 µF (no deviation permitted)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R (ensures stable performance across -55°C to 125°C)
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 4.60mm L × 2.00mm W × 2.20mm Max Thickness
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 1808AC153KAT1A meets all these criteria. The primary difference is the tolerance specification: the main part carries ±20% tolerance, while the substitute offers improved ±10% tolerance. This represents an upgrade in precision without altering electrical performance or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808AC153MATME and 1808AC153KAT1A are active production parts from KYOCERA AVX with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on the following factors:

1808AC153MATME is appropriate when:

• Bulk packaging is required for manual assembly or small-volume applications
• Standard ±20% tolerance meets circuit design requirements
• Current inventory availability is prioritized

1808AC153KAT1A is appropriate when:

• Tape & Reel packaging is required for automated assembly processes
• Improved ±10% tolerance is necessary for circuit performance or design margin
• Higher inventory availability (3100 pcs vs. 940 pcs) supports production schedules

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards. No functional performance difference exists between the two parts in applications where ±20% tolerance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can 1808AC153KAT1A be used as a direct replacement for 1808AC153MATME?

A: Yes. Both parts have identical capacitance (0.015 µF), voltage rating (1000V), temperature coefficient (X7R), package (1808), and physical dimensions. The substitute offers tighter tolerance (±10% vs. ±20%), which is an improvement. Packaging differs (Tape & Reel vs. Bulk), so assembly process compatibility must be confirmed.

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

A: Tolerance defines the acceptable range of actual capacitance values around the nominal 0.015 µF specification. The ±20% part allows values between 0.012 µF and 0.018 µF. The ±10% part allows values between 0.0135 µF and 0.0165 µF. Tighter tolerance (±10%) provides greater precision for applications sensitive to capacitance variation.

Q: Are there any mechanical compatibility issues when substituting between these parts?

A: No. Both parts use the 1808 (4520 Metric) package with identical physical dimensions (4.60mm L × 2.00mm W × 2.20mm Max Thickness). PCB footprints, solder pad layouts, and mounting procedures are identical.

Q: Does packaging type affect electrical performance?

A: No. Tape & Reel (TR) and Bulk packaging are distribution formats only. Electrical and thermal performance of the capacitor itself is unaffected. Packaging selection depends on assembly equipment and process requirements.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both 1808AC153MATME and 1808AC153KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental regulations. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What applications are these capacitors suitable for?

A: These high-voltage ceramic capacitors are designed for general-purpose applications. The 1000V rating and X7R temperature coefficient make them suitable for circuits requiring stable capacitance across wide temperature ranges and high-voltage environments.
