Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CBL2012T100M are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters:

• Inductance value: 10 µH (exact match required)
• Inductance tolerance: ±20% (must match or be tighter)
• Current rating: 370 mA minimum (equal or higher acceptable)
• DC resistance: 1.3 Ohm maximum (equal or lower acceptable)
• Core material: Ferrite (unshielded)
• Self-resonant frequency: 32 MHz (exact match)
• Test frequency: 100 kHz (exact match)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -40°C to 105°C (must support or exceed)

Compliance Parameters:

• RoHS3 compliance (required)
• Moisture Sensitivity Level: 1 (Unlimited)

Substitutes are grouped into two categories: Direct Equivalents (matching all electrical and mechanical specifications) and Similar Parts (matching core specifications with minor parameter variations that remain within acceptable operating margins).

Engineering Selection Recommendations

LSQNA201209T100M (Direct Equivalent - Recommended for Active Designs)

The LSQNA201209T100M is the primary substitute for the CBL2012T100M. This part maintains identical electrical specifications across all critical parameters: 10 µH inductance, 370 mA current rating, 1.3 Ohm maximum DC resistance, and 32 MHz self-resonant frequency. Both components share the same 0805 (2012 Metric) package footprint, operating temperature range, and RoHS3 compliance status. The LSQNA201209T100M is classified as Active, making it suitable for new circuit designs and long-term supply chain planning. The part is available in Tape & Reel packaging, consistent with the original component.

L0805C100MDWLT (Similar Substitute - Limited Application)

The L0805C100MDWLT from KEMET provides functional equivalence for applications where current requirements do not exceed 205 mA. This part matches the 10 µH inductance, ±20% tolerance, and 32 MHz self-resonant frequency of the main part. The DC resistance is 1 Ohm, which is lower than the 1.3 Ohm maximum of the CBL2012T100M, resulting in reduced power dissipation. Physical dimensions are slightly larger (0.083" L x 0.059" W versus 0.079" L x 0.049" W), and height is marginally increased (0.041" versus 0.039"). The L0805C100MDWLT is classified as Obsolete and is supplied in Cut Tape packaging rather than Tape & Reel. This part is suitable only for legacy system repairs or applications with confirmed current requirements below 205 mA saturation current.

Product Status Considerations

The CBL2012T100M is designated Not For New Designs. For new circuit implementations, the LSQNA201209T100M is the appropriate selection due to its Active status and full parameter equivalence. The L0805C100MDWLT should be reserved for maintenance and repair of existing systems where the lower current rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the LSQNA201209T100M be used as a direct replacement for the CBL2012T100M?

A: Yes. The LSQNA201209T100M is a direct equivalent. Both parts share identical inductance (10 µH), current rating (370 mA), DC resistance (1.3 Ohm maximum), package format (0805 / 2012 Metric), and operating temperature range (-40°C to 105°C). The LSQNA201209T100M is Active, making it the recommended choice for new designs.

Q: What are the limitations of the L0805C100MDWLT as a substitute?

A: The L0805C100MDWLT has a reduced current rating of 205 mA compared to the 370 mA rating of the CBL2012T100M. This part is suitable only for applications where the maximum continuous current does not exceed 205 mA. Additionally, the L0805C100MDWLT is classified as Obsolete and has slightly larger physical dimensions. Use this part only for legacy system maintenance where current requirements are confirmed to be within its rating.

Q: Are there any PCB layout considerations when substituting these parts?

A: The LSQNA201209T100M has identical footprint dimensions to the CBL2012T100M and requires no PCB layout modifications. The L0805C100MDWLT has slightly larger dimensions (0.083" L x 0.059" W versus 0.079" L x 0.049" W) and marginally greater height (0.041" versus 0.039"). Verify that PCB pad spacing and component clearances accommodate the L0805C100MDWLT before substitution.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The CBL2012T100M, LSQNA201209T100M, and L0805C100MDWLT are all ROHS3 Compliant. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging is supplied as individual segments cut from the carrier tape, typically used for smaller quantity orders or manual assembly. The CBL2012T100M and LSQNA201209T100M are supplied in Tape & Reel format. The L0805C100MDWLT is supplied in Cut Tape format.

Q: Can the L0805C100MDWLT be used in high-current applications?

A: No. The L0805C100MDWLT is rated for a maximum continuous current of 205 mA with a saturation current (Isat) specification not provided. The CBL2012T100M and LSQNA201209T100M are both rated for 370 mA continuous current with 205 mA saturation current. For applications requiring the full 370 mA rating, use the LSQNA201209T100M.

Q: What is the self-resonant frequency, and why is it important?

A: The self-resonant frequency (SRF) is the frequency at which the inductor's parasitic capacitance resonates with its inductance, causing the component to behave as a capacitor rather than an inductor. All three parts have an SRF of 32 MHz. This specification ensures that the inductor maintains its intended inductive behavior across the operating frequency range of the circuit. For applications operating near or above 32 MHz, component behavior must be verified against detailed frequency response data.

Q: Are there any thermal considerations when selecting a substitute?

A: All three parts operate across the same temperature range (-40°C to 105°C). The DC resistance values differ slightly: CBL2012T100M and LSQNA201209T100M are 1.3 Ohm maximum, while L0805C100MDWLT is 1 Ohm. Lower DC resistance results in reduced power dissipation and heat generation. For thermally constrained applications, the L0805C100MDWLT offers a slight advantage if current requirements permit its use.
