Key Parameters

Substitute Part Grouping Explanation

Substitution of the AISC-1210H-1R5N-T is determined by the following critical parameters:

• Inductance Value: Must be 1.5 µH to maintain circuit functionality
• Package Format: Must be 1210 (3225 Metric) for PCB compatibility
• Core Type: Must be drum core, wirewound with ferrite material
• Shielding Configuration: Must be unshielded
• Current Rating: Must meet or exceed 1.7 A
• DC Resistance: Should not significantly exceed 100mOhm to maintain performance characteristics
• Mounting Type: Must be surface mount

The BRL3225T1R5M from Taiyo Yuden meets all critical substitution criteria, offering improved electrical performance with higher current saturation capability and lower DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The BRL3225T1R5M serves as a direct functional substitute for the AISC-1210H-1R5N-T. Both components are ROHS3 compliant and carry MSL Level 1 ratings. The substitute part offers superior electrical characteristics, including lower DC resistance (54mOhm versus 100mOhm), higher current saturation capability (2.2A), and an extended operating temperature range (-40°C to 105°C versus -25°C to 85°C). The inductance tolerance is tighter on the substitute part (±20% versus ±30%), providing improved circuit predictability. Physical dimensions are comparable with the substitute featuring a lower profile (1.70mm versus 2.50mm seated height), which may provide layout advantages in space-constrained applications. Both parts maintain identical inductance values and package formats, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BRL3225T1R5M be used as a direct replacement for the AISC-1210H-1R5N-T?

A: Yes. Both components share identical inductance values (1.5 µH), package formats (1210/3225 Metric), core types (ferrite drum core wirewound), and shielding configurations (unshielded). The substitute meets or exceeds all critical electrical parameters required for functional equivalence.

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

A: The primary differences are DC resistance (54mOhm versus 100mOhm), current saturation rating (2.2A versus unspecified), inductance tolerance (±20% versus ±30%), operating temperature range (-40°C to 105°C versus -25°C to 85°C), and physical dimensions. The substitute provides improved performance across all measured parameters.

Q: Are there any PCB layout considerations when switching to the BRL3225T1R5M?

A: The substitute part has a lower seated height (1.70mm versus 2.50mm) and slightly smaller length dimension (3.20mm versus 4.60mm). These dimensional differences are minor and should not impact standard PCB layouts designed for 1210 package components. Verify clearance in your specific application if height-constrained.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AISC-1210H-1R5N-T and BRL3225T1R5M are ROHS3 compliant with MSL Level 1 ratings and EAR99 ECCN classification. Both carry the same HTSUS code (8504.50.8000).

Q: Why is the main part listed as obsolete?

A: The AISC-1210H-1R5N-T is classified as obsolete by the manufacturer. The BRL3225T1R5M, while marked as "Not For New Designs," remains available in production quantities and serves as the recommended equivalent for applications currently using the obsolete part.
