KGM44FR73D103KS Equivalent & Substitute Parts

Part Overview

The KGM44FR73D103KS is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 10000 pF with a 2000V (2kV) voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 package format is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitute parts for the KGM44FR73D103KS are identified based on strict parametric equivalence. The substitution logic is based on the following critical parameters that must remain constant:

Electrical Parameters (Non-negotiable):

• Capacitance value: 10000 pF
• Voltage rating: 2000V (2kV)
• Temperature coefficient: X7R
• Tolerance: ±10%

Mechanical Parameters (Non-negotiable):

• Package type: 1825 (4564 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.181" L x 0.248" W (4.60mm x 6.30mm)
• Thickness: 0.110" (2.80mm) maximum

Compliance Parameters (Required):

• RoHS3 compliance status
• Moisture sensitivity level: MSL 1

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The KGM44FR73D103KV is identified as a parametric equivalent based on identical electrical specifications, mechanical dimensions, and compliance certifications.

Parameter Comparison
