Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB2012T150K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 15 µH
• Inductance tolerance: ±10%
• Current rating: 320 mA continuous
• Saturation current: 170 mA minimum
• DC resistance: 1.69 Ohm maximum
• Self-resonant frequency: 28 MHz

Mechanical & Package Parameters:

• Package type: 0805 (2012 Metric) surface mount
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Maximum seated height: 0.057" (1.45mm)
• Core construction: Ferrite, unshielded wirewound

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 105°C
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must match all electrical specifications, maintain identical package dimensions, and satisfy the same environmental and regulatory requirements. The LSQNA201212T150K meets these criteria as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LSQNA201212T150K is a direct electrical and mechanical equivalent to the CB2012T150K. Both components are manufactured by Taiyo Yuden and share identical specifications across all critical parameters: inductance value, current ratings, DC resistance, package dimensions, and operating temperature range.

The primary distinction between these parts is product status. The CB2012T150K is designated "Not For New Designs," while the LSQNA201212T150K carries an "Active" status. This indicates that the LSQNA201212T150K represents the current production equivalent and is the appropriate selection for ongoing applications.

Both parts satisfy ROHS3 compliance and maintain MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage environments. The electrical performance, thermal characteristics, and mechanical fit are identical, permitting direct substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the LSQNA201212T150K be used as a direct replacement for the CB2012T150K?
