CDEP63MENP-R68MC Equivalent & Substitute Parts

Part Overview

The CDEP63MENP-R68MC is a 680 nH shielded surface mount inductor manufactured by Sumida America Components Inc. This component is rated for 9 A continuous current with a maximum DC resistance of 9.2 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 standards.

Substitute Part Grouping Explanation

Substitute parts for the CDEP63MENP-R68MC are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Primary Substitution Criteria:

• Inductance value: 680 nH (matching specification)
• Inductance tolerance: ±20% (matching specification)
• Shielding: Shielded construction required
• Mounting type: Surface Mount required
• Operating temperature range: -40°C to 125°C minimum
• RoHS3 compliance required
• Moisture Sensitivity Level: 1 (Unlimited) required

Secondary Compatibility Parameters:

• Current rating: Equal to or greater than 9 A
• DC resistance: Equal to or less than 9.2 mOhm
• Saturation current: Equal to or greater than 23.2 A
• Core material: Iron or Iron Powder acceptable

The substitute part SRP7030-R68M meets all primary criteria and demonstrates superior electrical performance in current rating and DC resistance, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SRP7030-R68M is a direct functional equivalent to the CDEP63MENP-R68MC. Both components share identical inductance specifications (680 nH ±20%), equivalent saturation current performance (23.2 A vs. 23 A), and matching environmental compliance certifications (ROHS3, REACH Unaffected, MSL 1).

Compliance and Regulatory Status:

Both the main part and substitute part maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental restrictions. Moisture sensitivity level 1 (unlimited) on both components indicates no special storage or handling requirements.

Performance Advantages of Substitute:

The SRP7030-R68M demonstrates superior electrical performance characteristics. The substitute part provides 15.5 A current rating compared to the main part's 9 A rating, and reduces DC resistance to 5.5 mOhm maximum versus 9.2 mOhm maximum. These improvements result in lower power dissipation and enhanced thermal performance in the application circuit.

Product Status Consideration:

The CDEP63MENP-R68MC is classified as obsolete, while the SRP7030-R68M maintains active product status with Bourns Inc. Active status ensures continued availability, technical support, and manufacturing consistency for long-term procurement requirements.

Physical Dimensions:

The substitute part exhibits minor dimensional variations. The SRP7030-R68M measures 7.80 x 7.00 mm with 3.20 mm maximum seated height, compared to the main part's 7.25 x 6.80 mm footprint with 3.00 mm height. PCB layout verification is required to confirm accommodation of these dimensional differences in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SRP7030-R68M directly replace the CDEP63MENP-R68MC in existing designs?

A: The SRP7030-R68M is electrically compatible as a direct substitute. Both components maintain 680 nH inductance at ±20% tolerance, operate across -40°C to 125°C, and provide shielded surface mount construction. Physical dimensions differ slightly; PCB layout verification is necessary to confirm footprint compatibility.

Q: What are the key electrical differences between these two inductors?

A: The SRP7030-R68M provides enhanced electrical performance. Current rating increases from 9 A to 15.5 A, and DC resistance decreases from 9.2 mOhm to 5.5 mOhm maximum. Saturation current remains equivalent at approximately 23 A. These improvements reduce power dissipation and thermal stress in the application circuit.

Q: Why is the CDEP63MENP-R68MC classified as obsolete?

A: The CDEP63MENP-R68MC is no longer in active production by Sumida America Components Inc. The SRP7030-R68M from Bourns Inc. maintains active status and provides equivalent or superior performance, making it the recommended alternative for new designs and ongoing procurement.

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

A: Both components maintain identical compliance certifications. ROHS3 compliance and REACH unaffected status apply to both the main part and substitute. Moisture sensitivity level 1 (unlimited) on both components indicates equivalent handling and storage requirements.

Q: What packaging options are available for the substitute part?

A: The SRP7030-R68M is supplied in Tape & Reel (TR) packaging format. The main part CDEP63MENP-R68MC packaging format is not specified in the technical data. Confirm packaging requirements for your procurement and assembly processes.

Q: How do the physical dimensions affect PCB design?

A: The SRP7030-R68M footprint (7.80 x 7.00 mm, 3.20 mm height) is slightly larger than the CDEP63MENP-R68MC (7.25 x 6.80 mm, 3.00 mm height). Verify that existing PCB layouts accommodate these dimensional increases. The nonstandard package format on both components requires confirmation of land pattern compatibility with your assembly specifications.

Q: What is the inductance test frequency for these components?

A: Both the CDEP63MENP-R68MC and SRP7030-R68M are tested at 100 kHz inductance frequency. This test frequency establishes the baseline inductance specification of 680 nH for both components.
