Substitute Part Grouping Explanation

The 1808AC153KAT1A qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• Capacitance: 0.015 µF (identical)
• Temperature Coefficient: X7R (identical)
• Package / Case: 1808 (4520 Metric) (identical)
• Physical Dimensions: 4.60mm L × 2.00mm W × 2.20mm Max Thickness (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Upgraded Parameter:

• Voltage Rating: 1000V (1kV) versus 630V (higher rating provides increased safety margin)
• Tolerance: ±10% versus ±20% (tighter tolerance specification)

The substitute part maintains full mechanical and electrical compatibility while providing enhanced voltage performance and improved capacitance tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both parts are Active products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for current and future applications. The 1808AC153KAT1A provides a higher voltage rating (1000V versus 630V) and tighter capacitance tolerance (±10% versus ±20%), making it suitable for applications requiring enhanced voltage margin or stricter capacitance specifications. The identical package footprint, mounting type, and thermal characteristics ensure direct PCB compatibility without layout modifications. Selection between these parts depends on circuit voltage requirements and tolerance specifications rather than mechanical or thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1808AC153KAT1A directly replace the 1808CC153MAT3A on existing PCBs?

A: Yes. Both parts use identical 1808 (4520 Metric) package dimensions and Surface Mount MLCC mounting type. No PCB layout changes are required.

Q: What is the primary difference between these two parts?

A: The 1808AC153KAT1A has a higher voltage rating (1000V versus 630V) and tighter capacitance tolerance (±10% versus ±20%). Capacitance value and temperature coefficient remain identical.

Q: Are there any thermal performance differences?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C with X7R temperature coefficient, ensuring equivalent thermal stability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 Compliant, REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. If the application operates at or below 630V, either part is acceptable. If higher voltage margin is desired or if tighter capacitance tolerance is required, the 1808AC153KAT1A is the appropriate choice.

Q: Is packaging different between these parts?

A: The main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Both contain identical components; packaging format differs only for handling and assembly automation.
