L1008Q2R2MDMIT Equivalent & Substitute Parts

Part Overview

The L1008Q2R2MDMIT is a 2.2 µH shielded multilayer inductor manufactured by KEMET, designed for surface mount applications in the 1008 (2520 Metric) package. This component is rated for 1.1 A maximum current with 150mOhm DC resistance and operates across the temperature range of -40°C to 85°C. The part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability for new production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L1008Q2R2MDMIT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Package / Case: 1008 (2520 Metric)
• Core material: Ferrite
• Shielding: Shielded
• Mounting type: Surface Mount
• Inductance test frequency: 1 MHz

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 1.1 A
• DC resistance: Substitute must equal or be lower than 150mOhm
• Operating temperature range: Substitute must encompass or exceed the original range
• Product status: Active substitutes are preferred for obsolete parts

The CVH252009-2R2M from Bourns Inc. meets all mandatory matching criteria and provides improved electrical performance characteristics, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CVH252009-2R2M is a direct functional substitute for the L1008Q2R2MDMIT. The Bourns component provides superior electrical performance with lower DC resistance (80mOhm versus 150mOhm) and higher current rating (1.3 A versus 1.1 A), while maintaining identical inductance, tolerance, package dimensions, and core material specifications.

The substitute part is classified as active product status, ensuring ongoing availability and supply chain support. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The extended operating temperature range of the Bourns part (-55°C to 125°C) provides additional thermal margin compared to the original KEMET component (-40°C to 85°C).

Physical compatibility is confirmed through identical package designation (1008 / 2520 Metric) and surface mount mounting type. The substitute part height of 0.039" (1.00mm) is lower than the original 0.079" (2.00mm), which may require PCB layout verification for clearance in confined spaces.

Frequently Asked Questions (FAQ)

Q: Can the CVH252009-2R2M directly replace the L1008Q2R2MDMIT in existing designs?

A: Yes. Both components share identical inductance (2.2 µH), tolerance (±20%), package (1008 / 2520 Metric), core material (ferrite), and shielding characteristics. The substitute provides improved DC resistance and current rating specifications.

Q: What are the physical compatibility considerations?

A: Both parts use the 1008 (2520 Metric) surface mount package with identical length (0.098" / 2.50mm) and width (0.079" / 2.00mm). The CVH252009-2R2M has a lower seated height of 0.039" (1.00mm) compared to 0.079" (2.00mm) for the original part. PCB layout clearance should be verified if height-sensitive applications are present.

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

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Regulatory status is equivalent.

Q: What is the temperature operating range difference?

A: The L1008Q2R2MDMIT operates from -40°C to 85°C. The CVH252009-2R2M operates from -55°C to 125°C. The substitute provides extended thermal range coverage in both directions.

Q: How do the DC resistance specifications compare?

A: The L1008Q2R2MDMIT specifies 150mOhm maximum DC resistance. The CVH252009-2R2M specifies 80mOhm maximum, representing a 47% reduction in resistive losses. This improvement reduces heat generation and power dissipation in the inductor.

Q: Is the current rating difference significant?

A: The L1008Q2R2MDMIT is rated for 1.1 A maximum current. The CVH252009-2R2M is rated for 1.3 A maximum current. The substitute provides 18% additional current capacity, offering design margin for applications operating near the original current limit.

Q: What packaging format differences exist?

A: The L1008Q2R2MDMIT is supplied in Cut Tape (CT) & Digi-Reel® format. The CVH252009-2R2M is supplied in Tape & Reel (TR) format. Packaging format selection depends on production volume and assembly equipment compatibility.
