Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCRH105RY-150 are qualified based on the following critical parameters:

• Inductance value of 15 µH with ±30% tolerance
• Current rating of 3.8 A or higher
• DC resistance of 41 mOhm or lower
• Shielded construction
• Surface mount configuration
• Nonstandard package dimensions compatible with 10.50mm x 10.30mm footprint
• Operating temperature range of -40°C minimum to 125°C maximum
• ROHS3 compliance

The identified substitute parts meet these electrical and mechanical criteria, ensuring functional equivalence in circuit applications requiring this inductor specification.

Parameter Comparison

Engineering Selection Recommendations

DR1050-150-R (Eaton - Electronics Division) is the primary substitute for SCRH105RY-150. This part maintains identical inductance, current rating, and operating temperature range. The DC resistance of 32.5 mOhm is lower than the 41 mOhm maximum specification, providing improved thermal performance. Physical dimensions and height are equivalent, ensuring PCB layout compatibility. Both parts are ROHS3 compliant with REACH Unaffected status and EAR99 classification.

CDRH105RNP-150NC (Sumida America Components Inc.) is a secondary substitute option. This part matches the inductance, tolerance, and DC resistance specifications. The current rating of 3.4 A is lower than the primary part's 3.8 A rating, making it suitable only for applications where the circuit current does not exceed 3.4 A. The operating temperature maximum is limited to 100°C compared to 125°C for the primary part. Physical dimensions are slightly smaller (10.20mm x 10.00mm versus 10.50mm x 10.30mm), which may require PCB layout verification. ROHS3 compliance is confirmed; REACH status is vendor undefined.

Selection should prioritize DR1050-150-R for applications requiring full current rating and extended temperature range. CDRH105RNP-150NC is acceptable only when circuit current remains below 3.4 A and operating temperature does not exceed 100°C.

Frequently Asked Questions (FAQ)

Q: Can CDRH105RNP-150NC be used in place of SCRH105RY-150 in all applications?

A: No. CDRH105RNP-150NC has a current rating of 3.4 A versus 3.8 A for SCRH105RY-150. Use CDRH105RNP-150NC only when circuit current does not exceed 3.4 A. Additionally, the maximum operating temperature is 100°C instead of 125°C.

Q: What are the physical compatibility considerations?

A: SCRH105RY-150 and DR1050-150-R share identical footprint dimensions (10.50mm x 10.30mm) and height (5.10mm), ensuring direct PCB compatibility. CDRH105RNP-150NC has slightly smaller dimensions (10.20mm x 10.00mm), requiring PCB layout verification before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SCRH105RY-150, CDRH105RNP-150NC, and DR1050-150-R are all ROHS3 compliant. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Which substitute offers the best thermal performance?

A: DR1050-150-R provides the lowest DC resistance at 32.5 mOhm maximum, compared to 41 mOhm for both SCRH105RY-150 and CDRH105RNP-150NC. Lower DC resistance reduces resistive heating in the inductor.

Q: What is the difference between the core materials?

A: SCRH105RY-150 core material is not specified in the provided data. CDRH105RNP-150NC and DR1050-150-R both use ferrite core material. DR1050-150-R is specifically identified as drum core, wirewound construction.

Q: Are there any export or regulatory restrictions?

A: All three parts are classified as EAR99 under ECCN regulations. SCRH105RY-150 and DR1050-150-R have REACH Unaffected status. CDRH105RNP-150NC has vendor undefined REACH status.
