CPL2508T2R2M Equivalent & Substitute Parts

Part Overview

The CPL2508T2R2M is a 2.2 µH shielded drum core, wirewound inductor manufactured by TDK Corporation, rated for 700 mA with a maximum DC resistance of 214.5 mOhm. This surface mount component operates across the temperature range of -40°C to 105°C and is housed in a nonstandard 2.50mm × 1.50mm package with a seated height of 0.80mm.

The CPL2508T2R2M is classified as obsolete. Locating equivalent or substitute parts is necessary to support ongoing production requirements, maintenance operations, and design continuity for applications currently utilizing this inductor.

Substitute Part Grouping Explanation

Substitution of the CPL2508T2R2M is based on the following critical parameters:

• Inductance Value: 2.2 µH (exact match required)
• Tolerance: ±20% (must be maintained)
• Core Type: Ferrite shielded drum core, wirewound construction
• Shielding: Shielded configuration
• Operating Temperature Range: -40°C to 105°C (minimum requirement)
• Mounting Type: Surface mount
• Current Handling Capability: Minimum 700 mA rating
• DC Resistance: Maximum 214.5 mOhm (electrical performance constraint)

The VLS252008ET-2R2M qualifies as a substitute based on matching inductance, tolerance, core material, shielding, temperature range, and mounting type. The substitute demonstrates improved current rating (840 mA) and saturation current (770 mA), providing enhanced performance margin. Physical dimensions differ slightly in width (2.00mm vs. 1.50mm), which must be evaluated for board layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The VLS252008ET-2R2M is a qualified substitute for the CPL2508T2R2M based on electrical parameter alignment and regulatory compliance. Both components are REACH unaffected and classified under ECCN EAR99.

The substitute part carries a "Not For New Designs" status, indicating it remains available but is not recommended for new product development. For applications currently using the obsolete CPL2508T2R2M, the VLS252008ET-2R2M provides functional equivalence with improved current handling margins.

The primary design consideration is the increased package width (2.00mm vs. 1.50mm). Board layout verification is required to confirm that the substitute component fits within existing PCB footprint constraints. The DC resistance increase from 214.5 mOhm to 290 mOhm must be evaluated against circuit performance requirements, particularly in applications sensitive to inductor losses.

Frequently Asked Questions (FAQ)

Q: Can the VLS252008ET-2R2M be used as a direct replacement for the CPL2508T2R2M?

A: Electrical substitution is valid based on matching inductance (2.2 µH), tolerance (±20%), core type (ferrite shielded), temperature range (-40°C to 105°C), and mounting type (surface mount). Physical board layout compatibility must be verified due to the 0.50mm increase in package width.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The VLS252008ET-2R2M exhibits 290 mOhm maximum DC resistance compared to 214.5 mOhm in the original part. This 35% increase in resistance results in higher power dissipation and heat generation. Circuit analysis is required to determine if this performance change is acceptable for the application.

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

A: Both components are REACH unaffected and classified as EAR99. Moisture sensitivity levels are identical (MSL 1, Unlimited). No regulatory barriers exist to substitution from a compliance perspective.

Q: Why does the substitute part have a higher current rating?

A: The VLS252008ET-2R2M is rated for 840 mA continuous current and 770 mA saturation current, compared to 700 mA for both parameters in the CPL2508T2R2M. The improved current handling capability provides additional design margin but does not alter the fundamental substitution criteria.

Q: What packaging format is the substitute available in?

A: The VLS252008ET-2R2M is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original CPL2508T2R2M used nonstandard packaging, making the substitute's standard packaging format advantageous for procurement and assembly operations.
