1808SC182KATME Equivalent & Substitute Parts

Part Overview

The 1808SC182KATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 1800 pF, rated voltage of 1500V (1.5kV), and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts may be required due to inventory availability, voltage rating requirements, or specific application constraints.

Substitute Part Grouping Explanation

The substitute part 1808HC182KAT1A is qualified as an equivalent based on the following matching parameters:

• Capacitance: 1800 pF (identical)
• Tolerance: ±10% (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Package / Case: 1808 (4520 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Size / Dimension: 0.181" L x 0.079" W (4.60mm x 2.00mm) (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)
• Manufacturer: KYOCERA AVX (same manufacturer)
• Product Status: Active (identical)

The primary difference is the rated voltage: the substitute part is rated at 3000V (3kV), which exceeds the original 1500V (1.5kV) rating. This represents an upgrade in voltage capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both parts are manufactured by KYOCERA AVX and maintain active product status with full ROHS3 compliance and REACH unaffected designation. The 1808HC182KAT1A substitute provides a higher voltage rating (3000V versus 1500V) while maintaining identical capacitance, tolerance, temperature coefficient, and operating temperature specifications. The substitute part exhibits a marginal increase in maximum thickness (0.087" versus 0.071"), which remains within typical PCB assembly tolerances for 1808 package components. Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions. Selection between these parts depends on circuit voltage requirements: the main part is suitable for applications rated at 1500V or below, while the substitute accommodates applications requiring higher voltage margins or operating at elevated voltage levels.

Frequently Asked Questions (FAQ)

Q: Can 1808HC182KAT1A be used as a direct replacement for 1808SC182KATME?

A: Yes, the 1808HC182KAT1A is electrically and mechanically compatible as a substitute. Both parts share identical capacitance (1800 pF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and package dimensions (1808 / 4520 Metric). The substitute provides higher voltage rating (3000V versus 1500V), making it suitable for applications requiring greater voltage headroom.

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

A: The rated voltage differs: 1808SC182KATME is rated at 1500V (1.5kV), while 1808HC182KAT1A is rated at 3000V (3kV). The substitute also has a slightly greater maximum thickness (0.087" versus 0.071"), though both remain within standard 1808 package specifications.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Both maintain MSL 1 (unlimited) moisture sensitivity level and are classified as active products by the manufacturer.

Q: Does the thickness difference affect PCB assembly?

A: The thickness increase from 0.071" to 0.087" is minimal and remains within standard tolerances for 1808 package components. This difference should not impact PCB assembly processes or board-level clearances in typical applications.

Q: What packaging formats are available?

A: The main part (1808SC182KATME) is available in bulk packaging. The substitute (1808HC182KAT1A) is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments.

Q: Can the substitute be used in applications originally designed for the main part?

A: Yes, provided the circuit voltage rating does not exceed 1500V. The substitute's higher voltage rating (3000V) makes it suitable for any application within the original 1500V specification. For applications requiring exactly 1500V operation, the substitute provides additional voltage margin and reliability headroom.
