Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPL2512T100M is determined by the following critical parameters:

• Inductance Value: Must be 10 µH with ±20% tolerance
• Shielding Configuration: Must be shielded to maintain electromagnetic isolation
• Core Material: Ferrite drum core construction required
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• Mounting Type: Surface mount configuration mandatory
• Current Handling Capability: Substitute must support minimum 300 mA continuous current rating

The VLS252012ET-100M qualifies as a direct substitute based on matching inductance, shielding, core material, temperature range, and mounting type. The substitute provides enhanced current rating (590 mA) and improved DC resistance characteristics (756mOhm), making it suitable for applications requiring the original CPL2512T100M specifications.

Parameter Comparison

Engineering Selection Recommendations

The VLS252012ET-100M serves as the primary substitute for the obsolete CPL2512T100M. Both components are manufactured by TDK Corporation and share identical inductance values, tolerance specifications, shielding configuration, and operating temperature range.

The VLS252012ET-100M provides superior electrical performance with a current rating of 590 mA compared to the original 300 mA specification, and reduced DC resistance of 756mOhm versus 1.17Ohm. These improvements ensure compatibility with the original design while offering enhanced thermal and current handling margins.

The VLS252012ET-100M is classified as "Not For New Designs," indicating limited availability for future production. For applications requiring long-term component sourcing, evaluation of additional alternatives from the VLS series or equivalent ferrite drum core inductors with matching electrical specifications is recommended.

Frequently Asked Questions (FAQ)

Q: Can the VLS252012ET-100M directly replace the CPL2512T100M in existing designs?

A: Yes. Both components share identical inductance (10 µH), tolerance (±20%), shielding, core material, operating temperature range (-40°C ~ 105°C), and surface mount configuration. The substitute provides higher current rating and lower DC resistance, making it electrically compatible.

Q: What is the primary difference between these two inductors?

A: The VLS252012ET-100M offers improved electrical performance with 590 mA current rating versus 300 mA, and 756mOhm DC resistance versus 1.17Ohm. Both maintain identical inductance and core specifications.

Q: Are there package dimension differences between CPL2512T100M and VLS252012ET-100M?

A: The CPL2512T100M uses a nonstandard package (0.098" L x 0.059" W, 2.50mm x 1.50mm). The VLS252012ET-100M uses a 1008 (2520 Metric) package (0.098" L x 0.079" W, 2.50mm x 2.00mm). The width dimension differs by 0.020" (0.50mm), requiring PCB layout verification before substitution.

Q: What compliance certifications apply to the VLS252012ET-100M?

A: The VLS252012ET-100M is RoHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (unlimited).

Q: Why is the CPL2512T100M classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by TDK Corporation. The VLS252012ET-100M represents the current equivalent offering with enhanced specifications.
