Key Parameters

Substitute Part Grouping Explanation

Substitute inductors for the SCRH5D28R-220 are qualified based on the following electrical and mechanical criteria:

Electrical Compatibility Parameters:

• Inductance value within ±30% tolerance band (19.4 µH to 24.6 µH acceptable range)
• Current rating equal to or greater than 1.58 A
• DC resistance not exceeding 119mOhm maximum
• Saturation current (Isat) at or above 950mA
• Operating temperature range covering -40°C to 125°C
• Inductance test frequency at 100 kHz

Mechanical Compatibility Parameters:

• Surface mount mounting type
• Nonstandard package classification
• Shielded construction
• Height seated maximum of 3.00mm or less
• Tape & Reel packaging format

The identified substitute parts meet these criteria while maintaining functional equivalence for circuit applications requiring fixed inductance filtering, energy storage, or impedance matching in the 20–22 µH range.

Parameter Comparison

Engineering Selection Recommendations

SD6030-220-R (Eaton - Electronics Division): This substitute maintains inductance at 20.4 µH (within ±30% tolerance), current rating of 1.57 A (equivalent to main part), and DC resistance of 122mOhm (within acceptable margin). Saturation current of 900mA is slightly lower than the main part's 950mA. All compliance certifications (RoHS, REACH Unaffected, EAR99) align with the main part. Physical dimensions (6.00mm × 6.00mm × 3.00mm) are compatible with the main part's footprint requirements. Product status is Active with 1242 units in stock.

SD7030-220-R (Eaton - Electronics Division): This substitute provides inductance at 21 µH (within ±30% tolerance) and improved saturation current of 1.2A (exceeding the main part's 950mA specification). Current rating is 1.4 A, which is lower than the main part's 1.58 A rating. DC resistance is 128mOhm, representing a 7.6% increase over the main part's maximum. Physical dimensions (7.00mm × 7.00mm × 3.00mm) remain within surface mount compatibility. All compliance certifications match the main part. Product status is Active with 1090 units in stock.

Frequently Asked Questions (FAQ)

Q: What determines if an inductor can substitute for the SCRH5D28R-220?

A: Substitution is determined by inductance value within the ±30% tolerance band (19.4–24.6 µH), current rating equal to or exceeding 1.58 A, DC resistance not exceeding 119mOhm, saturation current at or above 950mA, identical operating temperature range (-40°C to 125°C), surface mount configuration, shielded construction, and compatible package height (3.00mm maximum).

Q: Can SD7030-220-R be used if the application requires 1.58 A continuous current?

A: The SD7030-220-R is rated for 1.4 A continuous current, which is below the main part's 1.58 A specification. Selection depends on actual circuit current requirements. If the application demands the full 1.58 A rating, the SD6030-220-R (1.57 A) is the more appropriate substitute.

Q: Are there differences in core material between the main part and substitutes?

A: The main part (SCRH5D28R-220) does not specify core material in the provided data. Both substitute parts (SD6030-220-R and SD7030-220-R) use ferrite drum core, wirewound construction. This difference does not affect electrical equivalence within the specified parameter tolerances.

Q: Do all parts have identical RoHS compliance?

A: The main part is ROHS3 Compliant. Both substitutes are RoHS Compliant. Both certifications satisfy RoHS requirements; ROHS3 represents a more recent revision of the standard.

Q: What is the significance of the ±30% inductance tolerance?

A: The ±30% tolerance means the actual inductance value can range from 15.4 µH to 25.3 µH for the main part and substitutes. All identified substitutes fall within this acceptable range, ensuring functional equivalence in circuits designed for the 22 µH nominal value.

Q: Are the physical dimensions compatible for PCB layout?

A: The main part measures 6.30mm × 6.20mm. The SD6030-220-R measures 6.00mm × 6.00mm (smaller footprint). The SD7030-220-R measures 7.00mm × 7.00mm (larger footprint). All three maintain 3.00mm maximum seated height. PCB layout compatibility depends on specific pad spacing and clearance requirements in the target application.

Q: What is the moisture sensitivity level, and does it affect storage?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard storage conditions are acceptable without special desiccant or humidity control requirements.
