Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDH53NP-4R7MC are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value of 4.7 µH within ±20% tolerance
• Current rating sufficient to support the application (minimum 1.5 A acceptable for designs with margin)
• DC resistance within acceptable range for thermal and efficiency requirements
• Ferrite core construction with unshielded drum core topology

Mechanical Compatibility Criteria:

• Surface mount package configuration
• Nonstandard package dimensions compatible with PCB layout constraints
• Tape & Reel packaging for automated assembly

Compliance & Environmental Criteria:

• ROHS3 compliance
• MSL rating of 1 (Unlimited)
• Active product status ensuring continued availability

The SDR6603-4R7M from Bourns Inc. meets all substitution criteria within these parameters.

Engineering Selection Recommendations

CDH53NP-4R7MC Selection: Select the CDH53NP-4R7MC when the primary requirement is the 1.68 A current rating and the application operates within the -40°C to 100°C temperature window. This part is ROHS3 compliant and carries unlimited moisture sensitivity rating, suitable for standard manufacturing and storage conditions.

SDR6603-4R7M Selection: The SDR6603-4R7M from Bourns Inc. is suitable as a substitute when the application current requirement is 1.5 A or lower. This part offers an extended operating temperature range to 125°C and lower DC resistance (90 mOhm vs. 96 mOhm), providing improved thermal performance in current-limited applications. Both parts maintain ROHS3 compliance and MSL 1 rating. The SDR6603-4R7M is also currently in active production status.

Substitution Feasibility: Direct substitution of SDR6603-4R7M for CDH53NP-4R7MC is permissible in applications where the 1.5 A current rating is adequate. Applications requiring the full 1.68 A rating must retain the CDH53NP-4R7MC.

Frequently Asked Questions (FAQ)

Q: Can the SDR6603-4R7M replace the CDH53NP-4R7MC in all applications?

A: The SDR6603-4R7M can replace the CDH53NP-4R7MC only in applications where the circuit current does not exceed 1.5 A. The CDH53NP-4R7MC is rated for 1.68 A and must be used when higher current is required.

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

A: The CDH53NP-4R7MC measures 0.236" L x 0.205" W x 0.126" H (6.00mm x 5.20mm x 3.20mm). The SDR6603-4R7M measures 0.260" L x 0.175" W x 0.115" H (6.60mm x 4.45mm x 2.92mm). PCB layout must accommodate these dimensional variations.

Q: Are both parts available in Tape & Reel packaging?

A: Yes, both the CDH53NP-4R7MC and SDR6603-4R7M are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: Do both parts meet RoHS compliance requirements?

A: Yes, both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting standard environmental and regulatory requirements.

Q: What is the inductance tolerance for both parts?

A: Both parts carry an inductance tolerance of ±20%, ensuring equivalent performance within this specification window.

Q: Which part has better thermal performance?

A: The SDR6603-4R7M has lower DC resistance (90 mOhm vs. 96 mOhm) and an extended operating temperature range to 125°C, providing superior thermal characteristics in current-limited designs.
