Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1808CC153MAT9A is determined by the following critical parameters that must remain constant or improve:

• Capacitance Value: Must be 0.015 µF (no deviation permitted)
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Temperature Coefficient: Must be X7R for thermal stability equivalence
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Physical Dimensions: Must match 4.60mm L × 2.00mm W footprint
• Compliance: Must maintain ROHS3 and REACH compliance status

Voltage rating and tolerance may be upgraded (higher voltage, tighter tolerance) without compromising circuit functionality, provided the substitute part meets all other parameters. The 1808AC153KAT1A qualifies as a direct substitute with enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808CC153MAT9A and 1808AC153KAT1A are Active status components manufactured by KYOCERA AVX with identical ROHS3 and REACH compliance certifications. Selection between these parts depends on application voltage requirements and tolerance specifications:

The 1808CC153MAT9A is suitable for applications operating at or below 630V with tolerance requirements of ±20%.

The 1808AC153KAT1A provides enhanced specifications with 1000V (1kV) voltage rating and ±10% tolerance, making it applicable to higher-voltage circuits or designs requiring tighter capacitance tolerance. The 1kV rating provides additional design margin in high-voltage applications. Both parts share identical physical dimensions, thermal characteristics, and moisture sensitivity ratings, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 1808AC153KAT1A replace 1808CC153MAT9A in all applications?

A: Yes, the 1808AC153KAT1A is a direct substitute. It maintains identical capacitance (0.015 µF), package dimensions (1808 / 4520 Metric), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The higher voltage rating (1kV vs. 630V) and tighter tolerance (±10% vs. ±20%) represent improvements that do not restrict compatibility.

Q: Are there physical footprint differences between these parts?

A: No. Both parts use the 1808 (4520 Metric) package with identical dimensions: 4.60mm length, 2.00mm width, and 2.20mm maximum thickness. PCB layouts require no modification when substituting between these parts.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates a temperature coefficient of ±15% across the -55°C to 125°C operating range. This specification is identical for both parts, ensuring equivalent capacitance stability across temperature variations in the application environment.

Q: Does the ±10% tolerance of 1808AC153KAT1A provide measurable advantages?

A: The ±10% tolerance of 1808AC153KAT1A is tighter than the ±20% tolerance of 1808CC153MAT9A. This tighter tolerance reduces capacitance variation across production batches, beneficial for applications with strict capacitance specifications or precision filtering requirements.

Q: Are both parts available in the same packaging format?

A: The 1808CC153MAT9A is available in standard packaging, while 1808AC153KAT1A is supplied in Tape & Reel (TR) format. Both are Surface Mount MLCCs suitable for automated assembly processes. Verify packaging format compatibility with your procurement and assembly requirements.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components. MSL 1 rating indicates unlimited moisture sensitivity protection for both parts.
