Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH105A-151 is determined by the following critical parameters:

• Inductance Value: Must be 150 µH with ±20% tolerance
• Current Rating: Minimum 1.17 A continuous current capability
• Saturation Current (Isat): Minimum 1.2 A
• DC Resistance: Maximum 510mOhm to maintain thermal and efficiency characteristics
• Shielding: Must be shielded to prevent electromagnetic interference
• Mounting Type: Surface mount configuration required
• Operating Temperature: Must support -40°C to 125°C range
• Compliance: RoHS3 compliance and MSL 1 rating required

The DR124-151-R from Eaton - Electronics Division meets all substitution criteria within these parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

The DR124-151-R qualifies as a direct substitute for the SCRH105A-151 based on electrical parameter equivalence and compliance certification alignment. Both components maintain identical inductance values, tolerance specifications, and operating temperature ranges. The substitute part demonstrates superior performance in current handling capacity (1.3 A vs. 1.17 A) and lower DC resistance (445.2 mOhm vs. 510 mOhm), providing margin for thermal management in the application circuit.

Both parts carry Active product status with full RoHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility. The substitute maintains shielded construction and surface mount packaging, preserving electromagnetic isolation and PCB integration requirements.

Frequently Asked Questions (FAQ)

Q: Can the DR124-151-R replace the SCRH105A-151 in existing designs?

A: Yes. The DR124-151-R meets all electrical and mechanical substitution criteria. Identical inductance values, tolerance specifications, operating temperature ranges, and compliance certifications ensure functional equivalence. The substitute provides improved current handling and lower DC resistance.

Q: What are the physical dimension differences between these parts?

A: The SCRH105A-151 measures 0.413" L × 0.413" W × 0.236" H (10.50mm × 10.50mm × 6.00mm). The DR124-151-R measures 0.492" L × 0.492" W × 0.177" H (12.50mm × 12.50mm × 4.50mm). PCB layout verification is required to confirm fit within available space constraints.

Q: Are there packaging differences between the main part and substitute?

A: The SCRH105A-151 is supplied in nonstandard packaging. The DR124-151-R is supplied in Tape & Reel (TR) format. Verify packaging compatibility with assembly and procurement workflows.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SCRH105A-151 and DR124-151-R are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry EAR99 ECCN classification.

Q: What is the saturation current difference, and does it matter?

A: The SCRH105A-151 has Isat of 1.2 A; the DR124-151-R has Isat of 1.44 A. For applications operating at or near the 1.17 A rated current, the higher saturation current of the substitute provides additional margin before inductance degradation occurs.
