CDEP105MENP-1R8PC Equivalent & Substitute Parts

Part Overview

The CDEP105MENP-1R8PC is a 1.8 µH shielded inductor manufactured by Sumida America Components Inc., designed for surface mount applications requiring high current handling up to 10.5 A with low DC resistance of 7.44 mOhm maximum. This component features a metal composite core construction and operates across the industrial temperature range of -40°C to 125°C.

The CDEP105MENP-1R8PC is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications currently utilizing this inductor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDEP105MENP-1R8PC is determined by strict alignment of the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Inductance value: 1.8 µH (exact match required)
• Current rating: minimum 10.5 A (substitute must meet or exceed)
• DC resistance: maximum 7.44 mOhm (substitute must not exceed)
• Saturation current: minimum 19 A (substitute must meet or exceed)
• Shielding: shielded construction (required)
• Operating temperature range: -40°C to 125°C (minimum requirement)
• Inductance test frequency: 100 kHz

Mechanical Compatibility Criteria:

• Mounting type: surface mount (required)
• Package dimensions: compatible with 11.00mm x 10.00mm x 5.50mm maximum envelope
• RoHS3 compliance: required
• MSL rating: 1 (Unlimited) or equivalent

The substitute part VLM10555T-1R8M8R8-2 meets the inductance specification and shielding requirement. However, the current rating of 8.8 A falls below the 10.5 A requirement of the original part, and the DC resistance of 6.44 mOhm is lower than the 7.44 mOhm maximum specification. Physical dimensions are within acceptable tolerance of the original footprint.

Parameter Comparison

Engineering Selection Recommendations

The VLM10555T-1R8M8R8-2 from TDK Corporation is listed as an active product with current manufacturing support, providing supply chain continuity for the obsolete CDEP105MENP-1R8PC.

Compliance Status: Both parts maintain ROHS3 compliance and MSL rating 1 (Unlimited), ensuring compatibility with modern manufacturing and storage requirements.

Electrical Performance Considerations: The substitute part achieves the required 1.8 µH inductance specification with a tighter tolerance of ±20% compared to the original ±25%. DC resistance performance is superior at 6.44 mOhm maximum versus 7.44 mOhm maximum.

Current Handling Limitation: The substitute part is rated for 8.8 A continuous current and 18 A saturation current, both below the original part's 10.5 A and 19 A ratings respectively. Applications requiring the full 10.5 A current capacity of the CDEP105MENP-1R8PC cannot be directly substituted with the VLM10555T-1R8M8R8-2 without circuit redesign or parallel configuration analysis.

Physical Compatibility: Footprint dimensions of 10.60mm x 10.50mm x 5.60mm maximum are compatible with PCB layouts designed for the original 11.00mm x 10.00mm x 5.50mm envelope, with minimal clearance adjustment required.

Frequently Asked Questions (FAQ)

Q: Can the VLM10555T-1R8M8R8-2 directly replace the CDEP105MENP-1R8PC in all applications?

A: Direct substitution is limited by current rating. The VLM10555T-1R8M8R8-2 is rated for 8.8 A continuous current versus the original 10.5 A. Applications operating at or above 8.8 A require circuit analysis to confirm the substitute part meets thermal and performance requirements. Applications below 8.8 A are compatible.

Q: What are the key electrical parameters that must match for substitution?

A: The inductance value of 1.8 µH must be exact. Shielding type must be shielded construction. Operating temperature range must support -40°C to 125°C minimum. DC resistance and current ratings must meet or exceed application requirements.

Q: Are there physical footprint compatibility concerns?

A: The substitute part dimensions of 10.60mm L x 10.50mm W x 5.60mm H are compatible with PCB layouts designed for 11.00mm x 10.00mm x 5.50mm. Verify clearance around the component on the PCB to confirm adequate spacing.

Q: What is the significance of the inductance tolerance difference?

A: The substitute part offers ±20% tolerance versus the original ±25%. This tighter tolerance provides more predictable inductance values across the manufacturing range, which may improve circuit performance in applications sensitive to inductance variation.

Q: Does the substitute part maintain the same compliance certifications?

A: Yes. Both the CDEP105MENP-1R8PC and VLM10555T-1R8M8R8-2 are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring compatibility with current manufacturing standards and storage requirements.

Q: What is the packaging difference between these parts?

A: The CDEP105MENP-1R8PC packaging format is not specified in the original documentation. The VLM10555T-1R8M8R8-2 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.
