Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808AC153MAT9A is determined by the following critical parameters:

• Capacitance Value: Must be 0.015 µF
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 1808 (4520 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The identified substitute part 1808AC153KAT1A meets all these criteria. The primary difference is the tolerance specification, which is tighter (±10% versus ±20%), making it functionally compatible and suitable for applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808AC153MAT9A and 1808AC153KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and unlimited moisture sensitivity rating. The 1808AC153KAT1A offers improved tolerance performance (±10% versus ±20%), which provides tighter capacitance control without compromising any electrical or mechanical specifications. Both parts are suitable for general-purpose high-voltage applications within the specified operating temperature range. Selection between these parts depends on tolerance requirements and packaging preference (the substitute is supplied in Tape & Reel format).

Frequently Asked Questions (FAQ)

Q: Can 1808AC153KAT1A replace 1808AC153MAT9A in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, temperature coefficient, package dimensions, and operating temperature range. The substitute has tighter tolerance (±10% versus ±20%), which is a functional improvement.

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

A: No. Both parts use the 1808 (4520 Metric) package with identical dimensions (0.181" L x 0.079" W, 0.087" max thickness) and surface-mount mounting type.

Q: What is the difference in packaging between these parts?

A: The main part 1808AC153MAT9A uses standard packaging, while the substitute 1808AC153KAT1A is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements and supply chain availability. The 1808AC153KAT1A offers superior tolerance performance and has higher inventory availability (3100 units versus 1054 units).
