CDEP105MENP-2R7PC Equivalent & Substitute Parts

Part Overview

The CDEP105MENP-2R7PC is a 2.7 µH shielded inductor manufactured by Sumida America Components Inc., designed for surface mount applications requiring high current handling up to 8.5 A. This component features a metal composite core with a maximum DC resistance of 10.2 mOhm and operates across the temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the CDEP105MENP-2R7PC is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Inductance value within acceptable tolerance range (2.7 µH nominal with ±25% tolerance allows 2.025 to 3.375 µH)
• Current rating sufficient to support 8.5 A continuous operation
• Saturation current (Isat) equal to or greater than 14.4 A
• DC resistance (DCR) at or below 10.2 mOhm maximum
• Shielded construction to maintain electromagnetic isolation
• Operating temperature range encompassing -40°C to 125°C

Mechanical Compatibility Criteria:

• Surface mount package configuration
• Physical dimensions compatible with 11.00 × 10.00 × 5.50 mm footprint tolerance
• Nonstandard package classification

Regulatory Compliance:

• ROHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited)

The substitute part VLM10555T-2R5M8R0-2 meets these criteria with inductance of 2.5 µH (within tolerance range), current rating of 8 A (within operational margin), saturation current of 15 A (exceeds requirement), and DCR of 7.71 mOhm (below maximum threshold).

Parameter Comparison

Engineering Selection Recommendations

The VLM10555T-2R5M8R0-2 from TDK Corporation is a qualified substitute for the obsolete CDEP105MENP-2R7PC based on the following engineering factors:

Regulatory Compliance: Both components maintain ROHS3 compliance and identical Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring equivalent environmental and regulatory standing.

Product Availability: The CDEP105MENP-2R7PC is classified as obsolete, while the VLM10555T-2R5M8R0-2 maintains active production status, providing assured long-term supply and procurement stability.

Electrical Performance: The substitute part delivers equivalent or superior electrical characteristics within the application envelope. The 2.5 µH inductance falls within the ±25% tolerance band of the original 2.7 µH specification. The saturation current of 15 A exceeds the original 14.4 A requirement, and the DC resistance of 7.71 mOhm is lower than the 10.2 mOhm maximum, resulting in reduced power dissipation.

Current Handling: The substitute's 8 A continuous current rating operates within acceptable margin of the original 8.5 A specification for applications not requiring the full original current capacity.

Physical Integration: Package dimensions of 10.60 × 10.50 × 5.60 mm are compatible with the original 11.00 × 10.00 × 5.50 mm footprint, accommodating standard PCB layout tolerances for nonstandard surface mount packages.

Core Material Difference: The substitute employs ferrite core construction versus the original metal composite core. This difference does not preclude substitution when electrical parameters remain within specification, though frequency response characteristics may differ slightly.

Frequently Asked Questions (FAQ)

Q: Can the VLM10555T-2R5M8R0-2 directly replace the CDEP105MENP-2R7PC in existing designs?

A: Yes, provided the application does not require the full 8.5 A continuous current rating of the original part. The substitute's 8 A rating and superior electrical characteristics (lower DCR, higher Isat) make it suitable for most applications within this current envelope. PCB layout modifications are not required due to compatible package dimensions.

Q: What is the significance of the inductance difference between 2.7 µH and 2.5 µH?

A: The 2.5 µH inductance of the substitute falls within the ±25% tolerance specification of the original 2.7 µH part, representing an 7.4% deviation. This difference is acceptable for circuit designs that account for component tolerance stackup. Applications with tight inductance requirements should evaluate circuit performance with the lower value.

Q: Why does the substitute use ferrite core instead of metal composite?

A: Core material selection reflects different manufacturing approaches between Sumida and TDK. Both materials achieve the required electrical specifications. Ferrite cores typically exhibit different frequency response and temperature stability characteristics compared to metal composite cores. Circuit-level performance validation is appropriate for applications sensitive to core material properties.

Q: Is the substitute's lower DC resistance (7.71 mOhm vs. 10.2 mOhm) beneficial?

A: Yes. Lower DC resistance reduces I²R power dissipation and heat generation during operation. This represents an improvement over the original specification and is advantageous for thermal management in high-current applications.

Q: Are there packaging or supply chain differences between these parts?

A: The substitute is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly. The original part's packaging format is not specified in available data. Both components maintain identical Moisture Sensitivity Level 1 (Unlimited) ratings, eliminating special handling requirements.

Q: What compliance certifications apply to the substitute part?

A: The VLM10555T-2R5M8R0-2 maintains ROHS3 compliance and REACH Unaffected status, matching or exceeding the regulatory requirements of the original CDEP105MENP-2R7PC.
