Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCB63C-120 is determined by the following critical parameters:

• Inductance Value: Must be 12 µH to maintain circuit function
• Current Rating: Substitute must support minimum 1.8 A continuous current
• DC Resistance: Lower DCR values are acceptable; higher values may impact circuit performance
• Saturation Current: Must exceed application peak current requirements
• Physical Dimensions: Package footprint must match 6.20mm x 6.20mm with 3.00mm maximum height
• Shielding: Shielded construction required for EMI control
• Surface Mount Compatibility: Must be compatible with standard SMD assembly processes
• Environmental Compliance: RoHS3 compliance required

The SCRH5D28-120 meets these substitution criteria with improved electrical performance characteristics.

• Electrical Compatibility: Both components share identical inductance values and physical dimensions, enabling direct PCB footprint compatibility
• Performance Enhancement: The SCRH5D28-120 provides superior electrical characteristics with 30% higher current rating (2.35 A vs 1.8 A), 92% higher saturation current (1.15 A vs 600 mA), and 34% lower DC resistance (76 mOhm vs 115 mOhm)
• Compliance Alignment: Both components maintain ROHS3 compliance and identical environmental ratings
• Packaging: The SCRH5D28-120 is supplied in Tape & Reel format, supporting automated assembly processes

Frequently Asked Questions (FAQ)

Q: Can the SCRH5D28-120 be used as a direct replacement for SCB63C-120?

A: Yes. Both components have identical inductance values (12 µH), matching physical dimensions (6.20mm x 6.20mm footprint, 3.00mm height), and identical operating temperature ranges (-40°C to 125°C). The SCRH5D28-120 provides improved electrical performance with higher current rating and lower DC resistance.

Q: What are the key differences between these two inductors?

A: The primary differences are product status (SCB63C-120 is obsolete; SCRH5D28-120 is active), inductance tolerance (±20% vs ±30%), current rating (1.8 A vs 2.35 A), saturation current (600 mA vs 1.15 A), and DC resistance (115 mOhm vs 76 mOhm). The SCRH5D28-120 also uses Tape & Reel packaging.

Q: Are there any circuit design considerations when substituting these parts?

A: The lower DC resistance of the SCRH5D28-120 will reduce resistive losses in the circuit. The higher saturation current provides additional margin for transient current conditions. Both components maintain identical inductance values and thermal operating ranges, requiring no circuit redesign.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SCB63C-120 and SCRH5D28-120 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both have Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the significance of the inductance tolerance difference?

A: The SCB63C-120 has ±20% tolerance while the SCRH5D28-120 has ±30% tolerance. For applications requiring tighter inductance control, circuit design should account for the wider tolerance band of the substitute part.
