Substitute Part Grouping Explanation

Substitute components for the L1008C2R2MDMIT are identified based on strict equivalence across the following critical parameters:

Inductance Value: 2.2 µH (exact match required)
Current Rating: 1.3 A (minimum threshold)
Package / Case: 1008 (2520 Metric) (physical and electrical compatibility)
Shielding Type: Shielded (electromagnetic containment requirement)
Core Material: Ferrite (performance characteristic)
Mounting Type: Surface Mount (assembly compatibility)
DC Resistance: Must not exceed the application tolerance window

The CVH252009-2R2M from Bourns Inc. meets all substitution criteria with equivalent inductance, current rating, package dimensions, and shielding characteristics. The substitute component demonstrates improved DC resistance performance (80 mOhm Max versus 90 mOhm Max) and extended operating temperature range, making it suitable for direct replacement in existing designs.

Engineering Selection Recommendations

The CVH252009-2R2M from Bourns Inc. is the qualified substitute for the obsolete L1008C2R2MDMIT. Selection of this substitute component is supported by the following factors:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across supply chain transitions.

Product Availability: The CVH252009-2R2M maintains active product status with substantial inventory availability (87,900 pieces), providing supply chain security compared to the obsolete KEMET component.

Electrical Equivalence: Identical inductance value (2.2 µH), current rating (1.3 A), tolerance (±20%), and core material (ferrite) ensure functional compatibility in existing circuit designs.

Physical Compatibility: Matching package dimensions (1008 / 2520 Metric) and surface mount configuration enable direct PCB placement without layout modifications. The reduced seated height (1.00mm versus 2.00mm) presents a favorable design characteristic.

Performance Enhancement: The substitute component offers improved DC resistance (80 mOhm Max versus 90 mOhm Max) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), providing operational margin in thermal and electrical stress conditions.

Frequently Asked Questions (FAQ)

Q: Can the CVH252009-2R2M directly replace the L1008C2R2MDMIT in existing designs?

A: Yes. Both components share identical inductance (2.2 µH), current rating (1.3 A), tolerance (±20%), package dimensions (1008 / 2520 Metric), and shielding configuration. The substitute component is electrically and mechanically compatible for direct PCB replacement without circuit redesign.

Q: What is the significance of the DC resistance difference between the two components?

A: The CVH252009-2R2M exhibits lower maximum DC resistance (80 mOhm versus 90 mOhm). This represents improved electrical efficiency and reduced power dissipation in the inductor. Applications sensitive to resistive losses benefit from this performance characteristic.

Q: Does the reduced seated height of the CVH252009-2R2M affect PCB assembly?

A: The CVH252009-2R2M has a maximum seated height of 1.00mm compared to 2.00mm for the L1008C2R2MDMIT. This reduced profile is advantageous for space-constrained designs and does not create assembly compatibility issues. PCB footprints designed for the original component accommodate the substitute without modification.

Q: Are there temperature range considerations when substituting these components?

A: The CVH252009-2R2M operates across -55°C to 125°C, extending beyond the original component's -40°C to 85°C range. Applications operating within the original temperature specification experience no thermal compatibility issues. Designs requiring extended temperature operation benefit from the substitute component's broader operating range.

Q: What packaging formats are available for the CVH252009-2R2M?

A: The CVH252009-2R2M is supplied in Tape & Reel (TR) format. The original L1008C2R2MDMIT was available in Cut Tape (CT) and Digi-Reel® packaging. Procurement processes must account for packaging format differences when transitioning to the substitute component.

Q: Are both components compliant with current regulatory requirements?

A: Yes. Both the L1008C2R2MDMIT and CVH252009-2R2M maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement and use.
