CBC2012T100M Equivalent & Substitute Parts

Part Overview

The CBC2012T100M 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 CBC2012T100M carries a product status designation of "Not For New Designs," indicating that Taiyo Yuden has discontinued active development and support for this particular model line. 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 CBC2012T100M is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 10 µH
• Current rating: 340 mA minimum
• DC resistance: 1.56Ohm maximum
• Current saturation rating: 240mA minimum
• Self-resonant frequency: 40MHz
• Inductance test frequency: 2.52 MHz
• 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

Substitute parts must satisfy all three equivalence categories to ensure direct functional and physical interchangeability within existing circuit designs and PCB layouts.

Both parts maintain full compliance with RoHS3 and REACH regulatory requirements. Both components feature identical moisture sensitivity classification (MSL 1 - Unlimited), eliminating any handling or storage requirement differences.

For applications currently utilizing the CBC2012T100M, direct substitution with the LSQPA201212T100M requires no circuit modifications, PCB layout changes, or thermal management adjustments. The components are physically and electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the LSQPA201212T100M be used as a direct replacement for the CBC2012T100M in existing designs?

A: Yes. The LSQPA201212T100M is electrically and mechanically equivalent to the CBC2012T100M. All critical parameters—inductance, current rating, DC resistance, saturation current, operating temperature range, and physical dimensions—are identical. No circuit modifications or PCB layout changes are required.

Q: Why is the CBC2012T100M marked "Not For New Designs"?

A: This designation indicates that Taiyo Yuden has discontinued active development and support for the CB series inductor line. The LSQPA201212T100M represents the active equivalent within Taiyo Yuden's current product portfolio.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the CBC2012T100M and LSQPA201212T100M are RoHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). No compliance-related substitution barriers exist.

Q: Do these inductors have identical physical dimensions?

A: Yes. Both components are packaged in the 0805 (2012 Metric) form factor with identical length (0.079"), width (0.049"), and maximum seated height (0.057"). They occupy identical PCB footprint space.

Q: What is the saturation current specification, and does it differ between these parts?

A: Both parts have a saturation current (Isat) rating of 240mA. This specification defines the current level at which the inductor begins to exhibit nonlinear behavior due to core saturation. The identical rating confirms electrical equivalence.

Q: Are there any frequency-dependent performance differences?

A: No. Both parts share identical self-resonant frequency (40MHz) and inductance test frequency (2.52 MHz) specifications. Frequency response characteristics are equivalent across the operating bandwidth.

Q: What is the tolerance specification for these inductors?

A: Both the CBC2012T100M and LSQPA201212T100M carry a ±20% inductance tolerance. This tolerance applies to the 10 µH nominal inductance value, establishing the acceptable range of inductance variation between individual components.
