Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD6030-4R2-R is determined by the following criteria:

Mandatory Compatibility Parameters:

• Inductance value within ±30% tolerance band (3.87 µH to 5.33 µH)
• DC resistance not exceeding 31 mOhm maximum
• Shielded construction to maintain EMI performance
• Surface mount package configuration
• Ferrite core material

Acceptable Variation Parameters:

• Current rating may be lower if circuit design permits reduced current capacity
• Operating temperature range may be narrower if application operates within the substitute part's specified limits
• Physical dimensions may vary within PCB layout constraints

The CDRH5D28NP-4R2NC from Sumida America Components Inc. qualifies as a substitute based on inductance value (4.2 µH falls within the ±30% tolerance band), matching DC resistance specification (31 mOhm max), shielded construction, and surface mount configuration. The lower current rating (2.2 A versus 3.11 A) and narrower operating temperature range (-40°C to 100°C versus -40°C to 125°C) require circuit-level verification for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (SD6030-4R2-R): Select the SD6030-4R2-R when the application requires the full 3.11 A current rating and extended operating temperature range to 125°C. This part is RoHS Compliant and maintains active product status with established supply availability (3054 pcs in stock).

Substitute Part (CDRH5D28NP-4R2NC): The CDRH5D28NP-4R2NC is suitable for applications where circuit design permits operation at 2.2 A maximum current and the upper operating temperature limit of 100°C is acceptable. This part is ROHS3 Compliant and maintains active product status (2741 pcs in stock). The slightly reduced footprint (5.70mm x 5.70mm versus 6.00mm x 6.00mm) may provide PCB layout advantages in space-constrained designs.

Both parts share identical DC resistance specifications, shielding characteristics, and inductance tolerance bands, ensuring functional equivalence within their respective current and temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can the CDRH5D28NP-4R2NC replace the SD6030-4R2-R in all applications?

A: The CDRH5D28NP-4R2NC is functionally equivalent for inductance and DC resistance performance. However, substitution is limited to applications where the circuit operates at or below 2.2 A and the maximum operating temperature does not exceed 100°C. If the design requires the full 3.11 A rating or temperatures above 100°C, the SD6030-4R2-R is required.

Q: What is the inductance tolerance band for substitution?

A: Both parts carry ±30% inductance tolerance. The SD6030-4R2-R nominal value of 4.1 µH and the CDRH5D28NP-4R2NC nominal value of 4.2 µH both fall within the acceptable tolerance band (3.87 µH to 5.33 µH), confirming inductance compatibility.

Q: Are there physical dimension differences between these parts?

A: Yes. The SD6030-4R2-R measures 6.00mm x 6.00mm, while the CDRH5D28NP-4R2NC measures 5.70mm x 5.70mm. Both share the same 3.00mm maximum seated height. The smaller footprint of the substitute part may be accommodated in existing PCB layouts, but pad spacing and trace routing must be verified for the specific design.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS Compliant (SD6030-4R2-R is RoHS Compliant; CDRH5D28NP-4R2NC is ROHS3 Compliant). Both carry MSL 1 (Unlimited) ratings and are classified under ECCN EAR99 and HTSUS 8504.50.4000. REACH status differs: SD6030-4R2-R is REACH Unaffected, while CDRH5D28NP-4R2NC is Vendor Undefined.

Q: What is the saturation current specification?

A: The SD6030-4R2-R specifies a saturation current (Isat) of 2.2 A. The CDRH5D28NP-4R2NC does not provide a saturation current specification in the available data. This parameter should be obtained from the manufacturer if saturation performance is critical to the application.

Q: Can these parts be used interchangeably in tape and reel packaging?

A: Both parts are supplied in Tape & Reel (TR) packaging, supporting automated assembly processes. Physical dimension differences require verification of reel compatibility and pick-and-place machine programming adjustments.
