MBJCU31LAB7225KTPA01 Equivalent & Substitute Parts

Part Overview

The MBJCU31LAB7225KTPA01 is a 2.2 µF ceramic capacitor manufactured by Taiyo Yuden, rated for 50V with X7R temperature coefficient and housed in a 1206 (3216 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) is designed for applications requiring boardflex sensitivity and operates across a temperature range of -55°C to 125°C. The part is currently in active production status with soft termination features and ROHS3 compliance. Equivalent and substitute parts are identified to provide design flexibility, ensure supply chain continuity, and support component procurement strategies when the primary part is unavailable or when alternative qualified sources are required.

Substitute Part Grouping Explanation

Substitution of the MBJCU31LAB7225KTPA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 2.2 µF
• Tolerance: ±10%
• Voltage rating: 50V
• Temperature coefficient: X7R

Mechanical Parameters:

• Package type: 1206 (3216 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Maximum thickness: 0.071" (1.80mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 125°C
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must match all electrical specifications, maintain identical package dimensions for PCB layout compatibility, and satisfy the same environmental and regulatory requirements. The CL31B225KBHVPJE from Samsung Electro-Mechanics meets all substitution criteria and is qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations
