Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH105RY-820 is determined by the following critical parameters:

• Inductance value of 82 µH within ±30% tolerance
• Current rating of 1.45 A or higher
• DC resistance maximum of 227mOhm or lower
• Saturation current (Isat) of 1.5 A or higher
• Shielded construction
• Surface mount nonstandard package configuration
• Operating temperature range that encompasses the application requirements
• RoHS3 compliance and MSL 1 rating

The identified substitute CDRH105RNP-820NC from Sumida America Components Inc. meets these substitution criteria with equivalent electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SCRH105RY-820 and CDRH105RNP-820NC are active production components with ROHS3 compliance and MSL 1 ratings, making them suitable for applications requiring environmental and regulatory compliance. The CDRH105RNP-820NC from Sumida features a ferrite core material and maintains equivalent electrical specifications with a current rating of 1.45 A, which is compatible with the original 1.53 A rating. The operating temperature range of the Sumida substitute extends to 100°C maximum, compared to 125°C for the Signal Transformer part; applications operating above 100°C require the original SCRH105RY-820. Dimensional compatibility is maintained with minor variations within acceptable PCB layout tolerances.

Frequently Asked Questions (FAQ)

Q: Can CDRH105RNP-820NC be used as a direct replacement for SCRH105RY-820?

A: Yes, for applications operating within -40°C to 100°C. Both parts maintain 82 µH inductance, 227mOhm maximum DC resistance, and 1.5 A saturation current. The CDRH105RNP-820NC current rating of 1.45 A is compatible with the original 1.53 A specification. Applications requiring operation above 100°C must use the original SCRH105RY-820.

Q: Are there mechanical compatibility concerns between these parts?

A: Mechanical compatibility is maintained. The CDRH105RNP-820NC dimensions (10.20mm L x 10.00mm W x 5.10mm H) are slightly smaller than the SCRH105RY-820 (10.50mm L x 10.30mm W x 5.10mm H). Both use identical height and nonstandard package configurations, allowing PCB layout accommodation without redesign.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SCRH105RY-820 and CDRH105RNP-820NC are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, suitable for applications requiring environmental compliance.

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

A: The ±30% tolerance defines the acceptable inductance range from 57.4 µH to 106.6 µH. Both substitute parts maintain this tolerance specification, ensuring circuit performance within design parameters.

Q: How do the DC resistance specifications compare?

A: Both parts specify 227mOhm maximum DC resistance at the test frequency of 100 kHz, ensuring equivalent power dissipation and thermal characteristics in circuit applications.
