1808SC152KATME Equivalent & Substitute Parts

Part Overview

The 1808SC152KATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 1500 pF capacitance with 1.5 kV voltage rating and X7R temperature coefficient. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 1808 (4520 Metric) package is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The 1808GC152KAT1A qualifies as a direct substitute for the 1808SC152KATME based on the following matching parameters:

• Identical capacitance value: 1500 pF
• Identical tolerance: ±10%
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C to 125°C
• Identical package and case: 1808 (4520 Metric)
• Identical physical dimensions: 4.60mm L × 2.00mm W × 1.80mm Max Thickness
• Identical mounting type: Surface Mount, MLCC
• Identical RoHS and REACH compliance status
• Identical MSL rating: 1 (Unlimited)

The key differentiator is the voltage rating: the substitute part is rated at 2000V (2kV), which exceeds the original part's 1500V rating. This higher voltage rating maintains full backward compatibility while providing additional design margin in high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808SC152KATME and 1808GC152KAT1A are Active products from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1808GC152KAT1A provides a higher voltage rating (2kV versus 1.5kV) while maintaining all other electrical and mechanical specifications. Selection between these parts depends on circuit voltage requirements: use the 1808SC152KATME where the 1.5kV rating is sufficient, or select the 1808GC152KAT1A for applications requiring higher voltage margin or operating in elevated voltage environments. Both parts are suitable for general-purpose high-voltage applications with identical thermal stability and moisture handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1808GC152KAT1A replace the 1808SC152KATME in my circuit?

A: Yes. The 1808GC152KAT1A is a direct substitute with identical capacitance (1500 pF), tolerance (±10%), temperature coefficient (X7R), package dimensions (1808 / 4520 Metric), and operating temperature range (-55°C to 125°C). The substitute part has a higher voltage rating (2kV versus 1.5kV), which provides additional design margin and is fully backward compatible.

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

A: The primary difference is the voltage rating. The 1808SC152KATME is rated at 1500V, while the 1808GC152KAT1A is rated at 2000V. All other electrical parameters, physical dimensions, and compliance certifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1808 (4520 Metric) package with dimensions of 4.60mm length × 2.00mm width × 1.80mm maximum thickness. They are pin-compatible and require no PCB layout modifications.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and no special storage or handling requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1808SC152KATME and 1808GC152KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should I use for new designs?

A: For new designs, either part is acceptable based on your circuit voltage requirements. If your application operates at or below 1.5kV, either part is suitable. If higher voltage margin is desired or if the application may experience voltage transients, the 1808GC152KAT1A (2kV rating) is the preferred choice.
