Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCRH105RY-100 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance: 10 µH (exact match required)
• Inductance Tolerance: ±30% (exact match required)
• Current Rating: Minimum 4.5 A
• DC Resistance: Maximum 26 mOhm
• Shielding: Shielded configuration
• Mounting Type: Surface Mount
• Inductance Test Frequency: 100 kHz

Acceptable Variations:

• Packaging format (Tape & Reel vs. Cut Tape)
• Physical dimensions (within nonstandard package category)
• Manufacturer identity (different qualified suppliers)
• Operating temperature range (provided minimum -40°C is maintained)

The CDRH105RNP-100NC and CDRH125/LDNP-100NC meet these substitution criteria with matching or superior electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

CDRH105RNP-100NC is the primary substitute for SCRH105RY-100. This part maintains identical electrical specifications (10 µH, 4.5 A, 26 mOhm DCR) and physical height (5.10mm), with only minor dimensional variations in length and width. Both parts are RoHS3 compliant with MSL 1 rating. The operating temperature range of -40°C ~ 100°C is suitable for applications not requiring the extended 125°C upper limit of the original part. Packaging is available in Cut Tape and Digi-Reel formats.

CDRH125/LDNP-100NC is a secondary substitute option. While it maintains the 10 µH inductance and ±30% tolerance, it features a higher current rating (4.6 A) and slightly elevated DC resistance (29 mOhm Max). The larger physical footprint (12.00mm x 12.00mm, 6.00mm height) requires PCB layout verification. This part is suitable for applications where the increased current capacity provides design margin. RoHS3 compliance and MSL 1 rating are maintained.

Selection between substitutes depends on PCB space constraints and thermal operating requirements. Both substitutes are Active status products with full RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can CDRH105RNP-100NC be used as a direct replacement for SCRH105RY-100?

A: Yes. Both parts share identical inductance (10 µH), tolerance (±30%), current rating (4.5 A), and DC resistance (26 mOhm Max). Physical dimensions are comparable with matching seated height (5.10mm). Electrical performance is equivalent.

Q: What is the difference between CDRH105RNP-100NC and CDRH125/LDNP-100NC?

A: The primary differences are current rating (4.5 A vs. 4.6 A), DC resistance (26 mOhm vs. 29 mOhm), and physical size (10.20mm x 10.00mm vs. 12.00mm x 12.00mm). Both maintain 10 µH inductance. The CDRH125/LDNP-100NC is larger and has slightly higher resistance.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats do not affect component electrical characteristics. Selection is based on assembly process requirements and inventory handling preferences.

Q: Are there temperature range limitations with substitute parts?

A: CDRH105RNP-100NC operates from -40°C to 100°C, which is 25°C lower than the original SCRH105RY-100 (-40°C to 125°C). Applications requiring operation above 100°C must use the original part or verify thermal requirements with the substitute manufacturer.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. SCRH105RY-100, CDRH105RNP-100NC, and CDRH125/LDNP-100NC are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What PCB layout considerations apply to CDRH125/LDNP-100NC?

A: The CDRH125/LDNP-100NC has larger footprint dimensions (12.00mm x 12.00mm) compared to the original (10.50mm x 10.30mm). PCB pad layout and component placement must accommodate the larger package size. Seated height is also increased (6.00mm vs. 5.10mm).
