Key Parameters

Substitute Part Grouping Explanation

Substitution of the L1008S2R2MDMIT is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 2.2 µH with ±20% tolerance
• Package / Case: 1008 (2520 Metric) surface mount form factor
• Shielding type: Shielded construction
• Core material: Ferrite
• Inductance test frequency: 1 MHz

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 1.2 A
• DC resistance: Substitute must not exceed 115mOhm
• Operating temperature range: Substitute must support minimum -40°C ~ 85°C envelope
• RoHS and REACH compliance: Substitute must maintain ROHS3 Compliant and REACH Unaffected status

The CVH252009-2R2M from Bourns Inc. meets all critical matching parameters and exceeds performance specifications in current rating (1.3 A vs. 1.2 A) and DC resistance (80mOhm vs. 115mOhm), while maintaining full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The CVH252009-2R2M from Bourns Inc. is the direct functional equivalent for the obsolete L1008S2R2MDMIT. Selection of this substitute is supported by the following factors:

Compliance and Regulatory Status: Both components maintain ROHS3 Compliant and REACH Unaffected certifications, ensuring compatibility with current environmental and regulatory requirements.

Product Availability: The CVH252009-2R2M carries Active product status with substantial inventory availability (87,900 pcs), whereas the L1008S2R2MDMIT is classified as Obsolete. This transition ensures long-term supply chain continuity.

Electrical Performance: The substitute component exceeds the original specification in current rating capacity (1.3 A vs. 1.2 A) and provides superior DC resistance performance (80mOhm vs. 115mOhm), resulting in lower power dissipation and improved thermal characteristics.

Thermal Operating Range: The CVH252009-2R2M supports an extended operating temperature range (-55°C ~ 125°C) compared to the original part (-40°C ~ 85°C), providing additional margin for demanding thermal environments.

Physical Compatibility: Both components utilize identical footprint dimensions (0.098" L x 0.079" W / 2.50mm x 2.00mm) and the 1008 (2520 Metric) package, ensuring direct PCB layout compatibility. The substitute exhibits reduced seated height (0.039" vs. 0.079"), which presents no clearance concerns for standard assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CVH252009-2R2M directly replace the L1008S2R2MDMIT in existing designs?

A: Yes. Both components share identical inductance values (2.2 µH), inductance tolerance (±20%), package footprint (1008 / 2520 Metric), and shielding characteristics. The substitute meets or exceeds all electrical specifications of the original part.

Q: What are the key differences between these two inductors?

A: The primary differences are: (1) Current rating: CVH252009-2R2M is rated for 1.3 A versus 1.2 A for the L1008S2R2MDMIT; (2) DC resistance: CVH252009-2R2M has 80mOhm maximum versus 115mOhm for the original; (3) Operating temperature range: CVH252009-2R2M supports -55°C ~ 125°C versus -40°C ~ 85°C; (4) Seated height: CVH252009-2R2M is 0.039" versus 0.079" for the original; (5) Product status: CVH252009-2R2M is Active while L1008S2R2MDMIT is Obsolete.

Q: Are there any PCB layout modifications required when substituting the CVH252009-2R2M?

A: No PCB layout modifications are required. Both components use identical footprint dimensions (0.098" L x 0.079" W / 2.50mm x 2.00mm) and the same 1008 (2520 Metric) surface mount package. The reduced height of the substitute (0.039" vs. 0.079") does not create clearance issues.

Q: Do both components meet the same regulatory and compliance standards?

A: Yes. Both the L1008S2R2MDMIT and CVH252009-2R2M are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the packaging difference between these parts?

A: The L1008S2R2MDMIT is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the CVH252009-2R2M is supplied in Tape & Reel (TR) packaging. Both formats are standard for surface mount component distribution and are compatible with automated assembly equipment.

Q: Why is the L1008S2R2MDMIT classified as Obsolete?

A: The L1008S2R2MDMIT has reached end-of-life status with KEMET. The CVH252009-2R2M from Bourns Inc. is the recommended active equivalent for new designs and ongoing production requirements.

Q: Is the lower DC resistance of the CVH252009-2R2M beneficial?

A: Yes. The lower DC resistance (80mOhm vs. 115mOhm) of the CVH252009-2R2M results in reduced power dissipation and lower operating temperatures under the same current conditions, improving component reliability and thermal performance.
