CBC2012T100K Equivalent & Substitute Parts

Part Overview

The CBC2012T100K is a 10 µH unshielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 340 mA continuous current with a maximum DC resistance of 1.56Ohm. This component is packaged in the 0805 (2012 Metric) surface mount form factor and operates across the temperature range of -40°C to 105°C.

The CBC2012T100K carries a product status designation of "Not For New Designs," indicating that Taiyo Yuden has discontinued active development and support for this series. Organizations requiring this inductance value and electrical performance specification must identify equivalent alternatives from the manufacturer's active product portfolio to ensure long-term supply chain reliability and continued technical support.

Substitute Part Grouping Explanation

Substitution of the CBC2012T100K is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 10 µH
• Inductance tolerance: ±10%
• Current rating: 340 mA minimum
• Current saturation (Isat): 240 mA minimum
• DC resistance (DCR): 1.56Ohm maximum
• Self-resonant frequency: 40 MHz minimum
• Operating temperature range: -40°C to 105°C minimum

Mechanical Equivalence Criteria:

• Package / Case: 0805 (2012 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Maximum seated height: 0.057" (1.45mm)

Compliance Equivalence Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The LSQPA201212T100K from Taiyo Yuden meets all specified electrical, mechanical, and compliance parameters and qualifies as a direct substitute. The primary distinction is that LSQPA201212T100K carries an "Active" product status, ensuring ongoing manufacturer support and supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The LSQPA201212T100K is the direct equivalent substitute for the CBC2012T100K. Both components are manufactured by Taiyo Yuden and exhibit identical electrical performance, mechanical form factor, and compliance certifications across all specified parameters.

The primary engineering consideration for component selection is product status. The CBC2012T100K is designated "Not For New Designs," which indicates that Taiyo Yuden has transitioned this part to end-of-life status. The LSQPA201212T100K carries an "Active" product status, confirming that this component remains in the manufacturer's current production portfolio with ongoing technical support and supply chain continuity.

For applications requiring a 10 µH unshielded ferrite wirewound inductor in the 0805 surface mount package with 340 mA current rating and 1.56Ohm maximum DC resistance, the LSQPA201212T100K provides full electrical and mechanical compatibility with the legacy CBC2012T100K while ensuring long-term availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the LSQPA201212T100K be used as a direct replacement for the CBC2012T100K in existing designs?

A: Yes. The LSQPA201212T100K meets all electrical specifications, mechanical dimensions, and compliance requirements of the CBC2012T100K. Both components share identical inductance (10 µH), current rating (340 mA), DC resistance (1.56Ohm maximum), operating temperature range (-40°C to 105°C), and package form factor (0805 / 2012 Metric). No circuit modifications are required.

Q: What is the difference between the CBC2012T100K and LSQPA201212T100K?

A: The components are electrically and mechanically identical. The primary difference is product status: CBC2012T100K is designated "Not For New Designs," while LSQPA201212T100K is "Active." The LSQPA series represents Taiyo Yuden's current production line for this inductance specification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CBC2012T100K and LSQPA201212T100K are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these inductors?

A: Both components carry Moisture Sensitivity Level (MSL) 1, which designates unlimited shelf life without moisture control requirements.

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

A: Both components have a self-resonant frequency of 40 MHz. Applications operating near or above this frequency will experience reduced inductance and increased impedance. The inductance test frequency is specified at 2.52 MHz.

Q: Are there any differences in packaging between these parts?

A: Both components are supplied in Tape & Reel (TR) packaging in the 0805 (2012 Metric) form factor. Physical dimensions and maximum seated height are identical: 0.079" L x 0.049" W (2.00mm x 1.25mm) with 0.057" (1.45mm) maximum seated height.

Q: What is the saturation current specification?

A: Both components have a saturation current (Isat) of 240 mA. This represents the current level at which the inductor begins to exhibit nonlinear behavior due to core saturation. The continuous current rating of 340 mA exceeds this saturation point.
