Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDH53NP-2R2MC is determined by the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 2.2 µH (within ±20% tolerance band)
• Core type: Ferrite drum core, wirewound construction
• Shielding configuration: Unshielded
• Mounting: Surface mount, nonstandard package
• Current rating: Minimum 2.03 A
• DC resistance: Maximum 66mOhm
• RoHS3 compliance required

The SDR6603-2R2M from Bourns Inc. meets all primary substitution criteria. This part maintains the same inductance value, ferrite core material, unshielded configuration, and surface mount technology. The substitute part exceeds the minimum current rating requirement (2.4 A versus 2.03 A) and operates within acceptable DC resistance limits (70mOhm maximum versus 66mOhm maximum). Both parts are Active status products with full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

CDH53NP-2R2MC (Primary Part): The original Sumida part is recommended when inventory availability is confirmed and design specifications are locked to the exact current rating of 2.03 A. This part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating suitable for standard manufacturing environments.

SDR6603-2R2M (Substitute Part): The Bourns SDR6603-2R2M is a qualified substitute when the primary part is unavailable. This part provides equivalent inductance and core characteristics with enhanced current handling capability (2.4 A versus 2.03 A) and extended operating temperature range (-40°C to 125°C versus -40°C to 100°C). The DC resistance specification (70mOhm maximum) is within acceptable engineering variance for this component category. Both parts maintain identical RoHS3 compliance status and moisture sensitivity ratings. Physical dimensions differ slightly; verification of PCB layout compatibility is required prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can SDR6603-2R2M be used as a direct replacement for CDH53NP-2R2MC?

A: Yes, the SDR6603-2R2M qualifies as a substitute part. Both components maintain identical inductance values (2.2 µH), ferrite core construction, unshielded configuration, and surface mount technology. The substitute part meets or exceeds all electrical requirements of the original part.

Q: What are the physical dimension differences between these parts?

A: CDH53NP-2R2MC dimensions are 0.236" L x 0.205" W x 0.126" H (6.00mm x 5.20mm x 3.20mm). SDR6603-2R2M dimensions are 0.260" L x 0.175" W x 0.115" H (6.60mm x 4.45mm x 2.92mm). PCB layout verification is necessary to confirm fit within the available mounting space.

Q: Are there compliance or certification differences?

A: Both parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. The substitute part carries REACH Unaffected status, while the original part lists REACH as Vendor Undefined. Both parts are classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: What is the DC resistance difference impact?

A: The substitute part has a maximum DC resistance of 70mOhm compared to 66mOhm for the original part. This 4mOhm difference represents approximately 6% variance and is within acceptable engineering tolerance for this inductor category. Power dissipation calculations should account for this specification when thermal management is critical.

Q: Can the substitute part handle higher current applications?

A: The SDR6603-2R2M is rated for 2.4 A continuous current versus 2.03 A for the original part. The substitute part includes saturation current specification (2.3 A) not provided for the original part. Applications requiring the full 2.4 A capability should verify saturation performance requirements independently.

Q: What is the operating temperature range difference?

A: The substitute part operates across -40°C to 125°C, providing 25°C additional high-temperature capability compared to the original part's -40°C to 100°C range. This extended range may be beneficial for applications in elevated ambient or self-heating environments.
