Substitute Part Grouping Explanation

Substitution of the CPL2508T150M is based on the following critical parameters that must remain constant or compatible:

Fixed Requirements:

• Inductance value: 15 µH (±20% tolerance maintained)
• Shielding: Shielded configuration required
• Operating temperature range: -40°C to 105°C minimum
• Mounting type: Surface mount
• Moisture sensitivity: MSL 1 or better

Allowable Variations:

• Current rating: May exceed 230 mA (higher current capability acceptable)
• DC resistance: May be lower than 2.6Ohm (improved performance acceptable)
• Package dimensions: Physical size may differ if mechanical constraints permit
• Packaging format: Cut tape or tape & reel formats both acceptable
• Product status: Active or not for new designs acceptable

The VLS2010ET-150M qualifies as a direct substitute based on matching inductance, shielding, temperature range, and surface mount configuration, while offering improved electrical performance through higher current rating and lower DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The VLS2010ET-150M is a qualified substitute for the obsolete CPL2508T150M based on electrical parameter equivalence and compliance status. Both components maintain identical inductance values, tolerance specifications, operating temperature ranges, and shielding characteristics required for functional compatibility.

The substitute part offers performance improvements through increased current rating (400 mA versus 230 mA) and reduced DC resistance (1.476Ohm versus 2.6Ohm maximum), resulting in lower power dissipation and improved thermal performance in the application circuit.

Physical footprint differences (2.00mm × 2.00mm versus 2.50mm × 1.50mm) require PCB layout verification to confirm mechanical fit within the available board space. The substitute part's increased height (1.00mm versus 0.80mm) must also be evaluated against clearance constraints.

Both components maintain REACH compliance and carry identical moisture sensitivity ratings, ensuring equivalent handling and storage requirements. The substitute part is classified as "Not For New Designs" but remains suitable for legacy system support and production continuity applications.

Frequently Asked Questions (FAQ)

Q: Can VLS2010ET-150M replace CPL2508T150M in existing designs?

A: Yes, provided PCB layout accommodates the different footprint dimensions (2.00mm × 2.00mm × 1.00mm versus 2.50mm × 1.50mm × 0.80mm). Electrical performance is equivalent or superior across all critical parameters.

Q: What are the key compatibility criteria for this substitution?

A: Inductance value (15 µH), inductance tolerance (±20%), shielding configuration, operating temperature range (-40°C to 105°C), and surface mount mounting type must all remain constant. Current rating and DC resistance may improve without affecting circuit function.

Q: Does the lower DC resistance of VLS2010ET-150M affect circuit operation?

A: Lower DC resistance (1.476Ohm versus 2.6Ohm) reduces power dissipation and heat generation, generally improving circuit performance. No adverse effects are introduced by this parameter improvement.

Q: Are packaging format differences significant?

A: Both cut tape and tape & reel formats are compatible with surface mount assembly processes. Format selection depends on production volume and handling equipment capabilities rather than electrical compatibility.

Q: What must be verified before implementing this substitution?

A: PCB layout must confirm adequate space for the substitute part's footprint and height. No additional electrical or thermal verification is required due to equivalent or improved electrical characteristics.
