CB2016T2R2M Equivalent & Substitute Parts

Part Overview

The CB2016T2R2M is a 2.2 µH unshielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 1 A continuous current with a maximum DC resistance of 169 mOhm. This component is packaged in the 0806 (2016 Metric) surface mount form factor and is designed for applications requiring fixed inductance in compact configurations.

The CB2016T2R2M carries a product status of "Not For New Designs," indicating that Taiyo Yuden has transitioned this model out of active production. For new circuit designs and ongoing production requirements, equivalent substitute parts with active product status are available that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB2016T2R2M is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Current rating: 1 A
• Current saturation (Isat): 510 mA
• Self-resonant frequency: 70 MHz
• Operating temperature range: -40°C to 105°C

Mechanical Parameters (Must Match):

• Package / Case: 0806 (2016 Metric)
• Mounting type: Surface Mount
• Shielding configuration: Unshielded
• Core material: Ferrite

Compliance Parameters (Must Match):

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The LSQNA201616T2R2M from Taiyo Yuden satisfies all substitution criteria. While the DC resistance specification differs (130 mOhm versus 169 mOhm maximum), this represents an improvement in performance characteristics and remains within acceptable design parameters for applications originally specified for the CB2016T2R2M.

Parameter Comparison

Engineering Selection Recommendations

The LSQNA201616T2R2M is the direct equivalent substitute for the CB2016T2R2M. Both components are manufactured by Taiyo Yuden and maintain identical electrical specifications across inductance, current rating, saturation current, self-resonant frequency, and operating temperature range. Both are packaged in the 0806 (2016 Metric) surface mount form factor with unshielded ferrite cores.

The primary distinction between these parts is product lifecycle status. The CB2016T2R2M is designated "Not For New Designs," while the LSQNA201616T2R2M carries "Active" product status. This designation indicates that Taiyo Yuden continues to manufacture, support, and maintain supply of the LSQNA201616T2R2M for ongoing production and new circuit designs.

Both components satisfy ROHS3 compliance requirements and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling precautions are required during storage or assembly.

The LSQNA201616T2R2M exhibits a lower maximum DC resistance specification (130 mOhm versus 169 mOhm), which represents an improvement in electrical performance and reduces resistive losses in the inductor. This characteristic makes the LSQNA201616T2R2M suitable for direct substitution in applications originally designed with the CB2016T2R2M.

Frequently Asked Questions (FAQ)

Q: Can the LSQNA201616T2R2M be used as a direct replacement for the CB2016T2R2M in existing designs?

A: Yes. The LSQNA201616T2R2M is electrically and mechanically equivalent to the CB2016T2R2M. Both components share identical inductance values (2.2 µH), current ratings (1 A), saturation current (510 mA), self-resonant frequency (70 MHz), operating temperature range (-40°C to 105°C), and package form factor (0806 / 2016 Metric). No circuit modifications are required for substitution.

Q: What is the significance of the different DC resistance values between these parts?

A: The CB2016T2R2M specifies a maximum DC resistance of 169 mOhm, while the LSQNA201616T2R2M specifies 130 mOhm. The lower DC resistance of the LSQNA201616T2R2M reduces resistive losses and heat generation during operation. This represents an improvement in performance and does not create compatibility issues with circuits designed for the higher resistance specification.

Q: Are both parts suitable for new product designs?

A: The LSQNA201616T2R2M is designated as "Active" product status and is suitable for new designs. The CB2016T2R2M is designated "Not For New Designs" and should not be selected for new circuit development. For new designs, the LSQNA201616T2R2M is the appropriate choice.

Q: Do these inductors require special handling during assembly?

A: Both the CB2016T2R2M and LSQNA201616T2R2M carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage, handling, or assembly. Standard surface mount assembly processes are applicable.

Q: Are both parts RoHS compliant?

A: Yes. Both the CB2016T2R2M and LSQNA201616T2R2M are ROHS3 compliant and meet environmental regulatory requirements for restricted substances.

Q: Can these inductors be used in high-frequency applications?

A: Both inductors have a self-resonant frequency of 70 MHz. Applications operating below this frequency can utilize these components. At frequencies approaching or exceeding the self-resonant frequency, the inductor behavior transitions from inductive to capacitive, and performance characteristics degrade. Circuit design must account for this frequency limitation.

Q: What is the maximum continuous current these inductors can handle?

A: Both inductors are rated for 1 A continuous current at the specified operating temperature range (-40°C to 105°C). The saturation current (Isat) is 510 mA, representing the current level at which the inductor begins to saturate and inductance value degrades.
