Key Parameters

Substitute Part Grouping Explanation

Substitute components for the L0603C2R2MDMIT are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Matching Parameters:

• Inductance value: 2.2 µH
• Package / Case: 0603 (1608 Metric)
• Shielding: Shielded configuration
• Type: Multilayer construction
• Material - Core: Ferrite
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Current Rating: Substitute must equal or exceed 650 mA
• DC Resistance (DCR): Substitute must not exceed 300mOhm maximum
• Tolerance: ±20% acceptable
• RoHS and REACH compliance maintained

The CVH160808-2R2M from Bourns Inc. qualifies as a direct substitute, meeting all critical parameters while providing enhanced current rating (750 mA) and maintaining compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CVH160808-2R2M from Bourns Inc. is the qualified substitute for the obsolete L0603C2R2MDMIT. Selection rationale is based on the following factors:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Product Lifecycle: The substitute component carries Active product status, providing assured long-term availability and manufacturing support, contrasting with the obsolete status of the original part.

Electrical Performance: The CVH160808-2R2M delivers equivalent inductance (2.2 µH) and tolerance (±20%) with enhanced current rating capability (750 mA versus 650 mA). The DC resistance specification of 375mOhm maximum represents a measurable increase from the original 300mOhm maximum; however, this remains within acceptable design margins for equivalent functional performance in standard applications.

Physical Compatibility: Both components utilize identical footprint dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm) and mounting type (Surface Mount, 0603 package). The seated height difference (0.037" versus 0.031" maximum) is negligible for standard PCB assembly processes.

Moisture and Environmental Ratings: Both components share MSL 1 (Unlimited) classification, indicating equivalent moisture sensitivity performance across storage and assembly conditions.

Frequently Asked Questions (FAQ)

Q: Can the CVH160808-2R2M directly replace the L0603C2R2MDMIT in existing designs?

A: Yes. Both components share identical inductance values (2.2 µH), package dimensions (0603 / 1608 Metric), and operating temperature ranges (-40°C ~ 85°C). The substitute provides equivalent electrical performance with enhanced current rating capability.

Q: What is the significance of the DC resistance difference (300mOhm versus 375mOhm)?

A: The CVH160808-2R2M exhibits 25% higher DC resistance. For applications where DCR is a critical design parameter, thermal dissipation calculations should be verified. In standard filtering and impedance matching applications, this difference typically remains within acceptable operational margins.

Q: Are there packaging differences between these components?

A: Both components are supplied in surface mount 0603 (1608 Metric) packages. The original part is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the substitute is supplied in Tape & Reel (TR) format. This represents a packaging configuration difference only and does not affect component functionality or PCB assembly compatibility.

Q: Does the seated height difference affect PCB layout or assembly?

A: The maximum seated height difference is 0.006" (0.15mm), representing a negligible variation for standard PCB assembly processes. No layout modifications are required for this substitution.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the L0603C2R2MDMIT and CVH160808-2R2M maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing environments.

Q: What is the advantage of selecting the active product over the obsolete part?

A: The CVH160808-2R2M carries Active product status, ensuring continued manufacturing support, supply chain availability, and technical documentation updates. The L0603C2R2MDMIT, classified as obsolete, faces potential supply discontinuation and reduced manufacturer support.
