1808HC152MAT1A Equivalent & Substitute Parts

Part Overview

The 1808HC152MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 1500 pF and rated voltage of 3000V (3kV). This surface-mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient characteristics and is designed for general-purpose applications requiring high-voltage performance. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to inventory availability, packaging format preferences, or tolerance specification requirements.

Key Parameters

Substitute Part Grouping Explanation

The 1808HC152KAT1A qualifies as a direct substitute for the 1808HC152MAT1A based on the following critical parameters:

• Capacitance: Identical at 1500 pF
• Voltage Rating: Identical at 3000V (3kV)
• Temperature Coefficient: Identical X7R characteristic
• Operating Temperature Range: Identical -55°C ~ 125°C
• Package / Case: Identical 1808 (4520 Metric)
• Physical Dimensions: Identical footprint and thickness
• Compliance: Both ROHS3 compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary difference is the tolerance specification: the substitute part features ±10% tolerance compared to the original ±20% tolerance, representing a tighter tolerance specification. This difference does not prevent substitution; rather, it indicates the substitute part meets a more stringent tolerance requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808HC152MAT1A and 1808HC152KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1808HC152KAT1A is suitable for applications where tighter tolerance control (±10%) is beneficial or required. Selection between these parts should be based on tolerance requirements for the specific application and packaging format availability. Both parts meet identical electrical and mechanical specifications for high-voltage ceramic capacitor applications in the 1500 pF, 3kV category.

Frequently Asked Questions (FAQ)

Q: Can the 1808HC152KAT1A replace the 1808HC152MAT1A in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications. The substitute part features a tighter tolerance specification (±10% versus ±20%), which is compatible with applications designed for the original part.

Q: What is the difference between these two part numbers?

A: The primary difference is the capacitance tolerance: 1808HC152MAT1A specifies ±20% tolerance, while 1808HC152KAT1A specifies ±10% tolerance. Both parts are manufactured by KYOCERA AVX in the identical 1808 (4520 Metric) package with the same electrical ratings and compliance status.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical footprint dimensions of 0.181" L x 0.079" W (4.60mm x 2.00mm) and maximum thickness of 0.087" (2.20mm). They are fully compatible for PCB layout and assembly purposes.

Q: What packaging formats are available?

A: The 1808HC152MAT1A is available in standard packaging, while the 1808HC152KAT1A is supplied in Tape & Reel (TR) format. Selection depends on production volume and assembly equipment requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1808HC152MAT1A and 1808HC152KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
