SCRH105RY-220 Equivalent & Substitute Parts

Part Overview

The SCRH105RY-220 is a 22 µH shielded surface mount inductor manufactured by Signal Transformer, designed for applications requiring fixed inductance with moderate current handling. This component is rated for 3.07 A continuous current with a maximum DC resistance of 61 mOhm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting the same mechanical and environmental requirements.

Key Parameters

Substitute Part Grouping Explanation

The CDRH105RNP-220NC from Sumida America Components Inc. qualifies as a substitute based on the following alignment of critical parameters:

Inductance value matches at 22 µH with identical ±30% tolerance. DC resistance specification is equivalent at 61 mOhm maximum. Saturation current rating of 2.95 A meets the threshold for applications designed around the main part's 3.07 A rating. Both components feature shielded construction, surface mount configuration, and nonstandard package dimensions. Compliance certifications align: both parts carry ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The substitute part operates within -40°C to 100°C, which covers the lower portion of the main part's temperature range. Physical dimensions differ slightly but remain compatible with the same mounting footprint classification.

Parameter Comparison

Engineering Selection Recommendations

Both the SCRH105RY-220 and CDRH105RNP-220NC maintain Active product status with full regulatory compliance. Selection between these parts depends on application-specific current and temperature requirements.

The SCRH105RY-220 supports continuous operation at 3.07 A across the extended temperature range of -40°C to 125°C. The CDRH105RNP-220NC operates at a lower continuous current rating of 2.9 A with a maximum operating temperature of 100°C. Applications requiring sustained operation above 100°C or continuous currents exceeding 2.9 A must use the primary part. Applications operating within -40°C to 100°C and drawing maximum 2.9 A continuous current may use either part interchangeably.

Both components carry identical inductance, tolerance, saturation current, DC resistance, and compliance certifications, ensuring electrical equivalence within their respective operating envelopes.

Frequently Asked Questions (FAQ)

Q: Can CDRH105RNP-220NC replace SCRH105RY-220 in all applications?

A: Substitution is valid only when the application operates within -40°C to 100°C and does not require continuous current exceeding 2.9 A. Applications requiring the full 3.07 A rating or temperatures above 100°C must use the SCRH105RY-220.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use nonstandard package configurations with similar mounting footprints. SCRH105RY-220 measures 0.413" L × 0.406" W × 0.201" H (10.50mm × 10.30mm × 5.10mm). CDRH105RNP-220NC measures 0.402" L × 0.394" W × 0.201" H (10.20mm × 10.00mm × 5.10mm). Height is identical; length and width differ by approximately 1-2%, which may require PCB layout verification.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both SCRH105RY-220 and CDRH105RNP-220NC are ROHS3 compliant, REACH unaffected, carry EAR99 ECCN classification, and feature MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the significance of the saturation current specification?

A: Saturation current (Isat) of 2.95 A indicates the threshold at which inductance begins to degrade. Both parts share this specification, ensuring consistent performance characteristics up to this current level.

Q: How do the DC resistance values compare?

A: Both parts specify 61 mOhm maximum DC resistance at the test frequency of 100 kHz, ensuring equivalent power dissipation and thermal performance in equivalent circuit applications.
