CB2012T220K Equivalent & Substitute Parts

Part Overview

The CB2012T220K is a 22 µH unshielded drum core wirewound inductor manufactured by Taiyo Yuden, designed for surface mount applications in the 0805 (2012 Metric) package. This component is rated for 280 mA continuous current with a maximum DC resistance of 2.21 Ohm and operates across the temperature range of -40°C to 105°C.

The CB2012T220K carries a product status of "Not For New Designs," indicating that Taiyo Yuden has transitioned this part to end-of-life status. Identification of equivalent substitute parts is necessary for ongoing production support, maintenance applications, and design continuity where existing inventory requires replenishment or where new designs require active product alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB2012T220K is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters:

• Inductance value: 22 µH
• Inductance tolerance: ±10%
• Current rating: 280 mA minimum
• DC resistance: 2.21 Ohm maximum
• Self-resonant frequency: 16 MHz
• Saturation current: 135 mA minimum

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Mounting type: Surface Mount
• Core material: Ferrite
• Shielding configuration: Unshielded

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 105°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts must satisfy all electrical specifications within the stated tolerances, maintain identical package dimensions and mounting characteristics, and comply with the same environmental and regulatory standards. The LSQNA201212T220K meets these criteria as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LSQNA201212T220K is a direct functional equivalent to the CB2012T220K across all electrical, mechanical, and environmental specifications. Both components are manufactured by Taiyo Yuden and share identical inductance values, current ratings, DC resistance characteristics, package dimensions, and operating temperature ranges.

The primary distinction between these parts is product lifecycle status. The CB2012T220K is designated "Not For New Designs," while the LSQNA201212T220K maintains "Active" status. For applications requiring ongoing component availability and long-term supply chain stability, the LSQNA201212T220K is the appropriate selection. Both parts satisfy ROHS3 compliance and MSL Level 1 requirements, ensuring compatibility with standard surface mount assembly processes and environmental regulations.

The LSQNA201212T220K operates within the identical electrical performance envelope as the CB2012T220K, with no derating or performance adjustment required for direct substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the LSQNA201212T220K be used as a direct replacement for the CB2012T220K in existing designs?

A: Yes. The LSQNA201212T220K is electrically and mechanically identical to the CB2012T220K. All critical parameters including inductance, current rating, DC resistance, package dimensions, and operating temperature range are equivalent. Direct substitution requires no circuit modifications or performance adjustments.

Q: What is the significance of the "Not For New Designs" status on the CB2012T220K?

A: This designation indicates that Taiyo Yuden has transitioned the CB2012T220K to end-of-life status and is no longer recommending it for new product development. The LSQNA201212T220K, with "Active" product status, is the current production equivalent and is suitable for both new designs and ongoing production support.

Q: Are the physical dimensions and package specifications identical between these two parts?

A: Yes. Both the CB2012T220K and LSQNA201212T220K are packaged in the 0805 (2012 Metric) form factor with identical length (0.079"), width (0.049"), and maximum seated height (0.057"). They are mechanically interchangeable on standard surface mount assembly equipment.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both components are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity ratings, and operate across the identical temperature range of -40°C to 105°C. They satisfy equivalent regulatory and environmental requirements for industrial and commercial applications.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching inductance (22 µH), tolerance (±10%), current rating (280 mA), saturation current (135 mA), DC resistance (2.21 Ohm maximum), and self-resonant frequency (16 MHz). The LSQNA201212T220K meets all these specifications identically to the CB2012T220K.

Q: Is the LSQNA201212T220K available in the same packaging format (Tape & Reel)?

A: Yes. The LSQNA201212T220K is supplied in Tape & Reel (TR) packaging, consistent with the CB2012T220K, enabling compatibility with automated assembly processes and standard component handling procedures.
