Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH105RY-221 is determined by the following critical parameters:

• Inductance Value: 220 µH ±30% tolerance
• Current Rating: Minimum 930 mA continuous current capability
• Saturation Current (Isat): Minimum 940 mA
• DC Resistance: 500 mOhm maximum
• Shielding: Shielded construction required
• Mounting: Surface mount configuration
• Package: Nonstandard form factor with compatible footprint dimensions
• Compliance: RoHS3 compliant status

The CDRH105RNP-221NC meets all substitution criteria within these parameters and is therefore classified as an equivalent substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the SCRH105RY-221 and CDRH105RNP-221NC are Active product status components with RoHS3 compliance and EAR99 export classification. The CDRH105RNP-221NC provides equivalent electrical performance with a 10 mA higher current rating (940 mA vs. 930 mA) and identical saturation current specification. Physical dimensions are within acceptable tolerance for standard PCB footprints, with the substitute part measuring slightly smaller in length and width but marginally taller in seated height. The operating temperature range of the substitute part extends to 100°C maximum compared to 125°C for the original part; this difference must be evaluated against specific application thermal requirements. Both components feature ferrite core construction (where specified) and identical DC resistance ratings.

Frequently Asked Questions (FAQ)

Q: Can the CDRH105RNP-221NC be used as a direct replacement for the SCRH105RY-221?

A: Yes, the CDRH105RNP-221NC meets all critical electrical substitution parameters: identical 220 µH inductance value, equivalent ±30% tolerance, saturation current of 940 mA, and maximum DC resistance of 500 mOhm. Both components are shielded surface mount inductors with RoHS3 compliance and MSL 1 rating.

Q: What are the physical compatibility considerations?

A: The CDRH105RNP-221NC dimensions are 0.402" L x 0.394" W (10.20mm x 10.00mm) compared to the original 0.413" L x 0.406" W (10.50mm x 10.30mm). Seated heights are 0.205" (5.20mm) and 0.201" (5.10mm) respectively. These minor dimensional differences are typically accommodated within standard PCB design tolerances for nonstandard form factor inductors.

Q: Are there temperature rating differences?

A: The SCRH105RY-221 operates from -40°C to 125°C, while the CDRH105RNP-221NC operates from -40°C to 100°C. Applications requiring operation above 100°C must use the original SCRH105RY-221 part.

Q: Do both parts have identical current handling specifications?

A: The SCRH105RY-221 is rated for 930 mA continuous current with 940 mA saturation current. The CDRH105RNP-221NC is rated for 940 mA continuous current with identical 940 mA saturation current. The substitute part provides marginally higher current capacity.

Q: What is the packaging format for both parts?

A: Both components are supplied in Tape & Reel (TR) packaging with MSL 1 (Unlimited) moisture sensitivity level, suitable for automated assembly processes.
