CDEP63MENP-100MC Equivalent & Substitute Parts

Part Overview

The CDEP63MENP-100MC is a 10 µH shielded surface mount inductor manufactured by Sumida America Components Inc. This component is rated for 2.1 A continuous current with a maximum DC resistance of 113.8 mOhm and operates across the temperature range of -40°C to 125°C. The part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance within the specified inductance, current rating, and DC resistance parameters while meeting equivalent environmental and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the CDEP63MENP-100MC are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters:

• Inductance value of 10 µH (exact match required)
• Current rating equal to or greater than 2.1 A
• DC resistance at or below 113.8 mOhm maximum
• Saturation current (Isat) sufficient to support circuit peak current demands
• Shielded construction for EMI containment

Environmental & Compliance Parameters:

• Operating temperature range of -40°C to 125°C minimum
• ROHS3 compliance certification
• Moisture Sensitivity Level (MSL) of 1 or equivalent
• REACH unaffected status

Mechanical Parameters:

• Surface mount package configuration
• Physical dimensions compatible with PCB layout constraints

The SRP7030-100M from Bourns Inc. meets all substitution criteria and is classified as an active product, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

The SRP7030-100M is the qualified substitute for the obsolete CDEP63MENP-100MC based on the following engineering criteria:

Electrical Equivalence: The SRP7030-100M maintains the required 10 µH inductance with identical ±20% tolerance. The substitute's 3 A current rating exceeds the 2.1 A requirement of the main part, providing design margin. The DC resistance of 85 mOhm is lower than the 113.8 mOhm maximum specification, resulting in reduced power dissipation and improved thermal performance. Saturation current ratings (4.5 A vs. 4.6 A) are functionally equivalent.

Compliance & Certification: Both components maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. Operating temperature ranges are identical (-40°C to 125°C), ensuring thermal compatibility across all specified environments.

Supply Chain Continuity: The SRP7030-100M is classified as an active product with 3430 units in stock, compared to the obsolete CDEP63MENP-100MC status. This ensures long-term availability and procurement reliability.

Physical Compatibility: Both components are surface mount inductors with nonstandard packages. Dimensional differences are minimal (length difference of 0.022", width difference of 0.008", height difference of 0.008"). PCB layout verification is required to confirm footprint compatibility and clearance around the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the SRP7030-100M directly replace the CDEP63MENP-100MC without circuit modification?

A: The SRP7030-100M is electrically equivalent for the specified circuit parameters. The 10 µH inductance, operating temperature range, and shielding characteristics are identical. However, physical dimensions differ slightly. PCB layout verification is required to confirm that the substitute component fits within the existing footprint and clearance constraints. No circuit modifications are necessary if physical placement is compatible.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The SRP7030-100M has a maximum DC resistance of 85 mOhm compared to 113.8 mOhm in the main part. Lower DC resistance reduces I²R power losses and heat generation during operation. This represents an improvement in thermal performance and efficiency. The circuit will operate within specification with either value, as the main part's resistance is the maximum allowable limit.

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

A: Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL 1 ratings. No compliance or regulatory differences exist. Both parts are suitable for applications requiring these certifications.

Q: Why is the substitute part rated for 3 A when the original is only 2.1 A?

A: The higher current rating of the SRP7030-100M (3 A vs. 2.1 A) indicates improved thermal design or core material characteristics. This provides additional design margin and allows the component to handle transient current spikes without saturation. The circuit designed for 2.1 A operation will function reliably with the higher-rated substitute.

Q: What should be verified before implementing the SRP7030-100M as a substitute?

A: Verification steps include: (1) Confirm PCB footprint compatibility given the dimensional differences of 0.022" length and 0.008" width; (2) Verify vertical clearance, as the substitute is 0.008" taller; (3) Confirm that the slightly larger package does not interfere with adjacent components or assembly processes; (4) Validate that the lower DC resistance does not introduce unintended circuit behavior in current-limiting or impedance-matching applications.

Q: Is the SRP7030-100M available in the same packaging format?

A: The SRP7030-100M is supplied in Cut Tape (CT) and Digi-Reel® packaging, providing standard surface mount component handling and automated assembly compatibility. The main part packaging information was not specified in the original documentation. Both formats support standard PCB assembly processes.
