Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC414MF-2R2 is based on the following critical parameters:

• Inductance Value: 2.2 µH with ±20% tolerance
• Current Rating: Minimum 1.78 A continuous current capability
• Saturation Current (Isat): 1.9 A minimum
• Shielding: Shielded construction required
• Mounting: Surface mount configuration
• Operating Temperature: Compatibility within specified range
• Compliance: ROHS3 and REACH compliance maintained

The substitute part 1231AS-H-2R2M=P3 from Murata Electronics meets all critical electrical parameters while offering improved performance characteristics in DC resistance and current rating capacity.

Parameter Comparison

Engineering Selection Recommendations

The 1231AS-H-2R2M=P3 serves as a direct substitute for the obsolete SC414MF-2R2. Both components maintain identical inductance values, tolerance specifications, and saturation current ratings. The substitute part provides superior DC resistance performance at 48 mOhm maximum compared to 124 mOhm maximum of the original part, resulting in lower power dissipation and improved thermal characteristics.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage protocols. The substitute part is currently in active production status with established supply chain availability, addressing the obsolescence constraint of the original component.

The operating temperature range of the substitute part (-40°C to 85°C) covers the lower portion of the original part's range (-40°C to 125°C). Applications requiring operation above 85°C must evaluate thermal requirements independently.

Frequently Asked Questions (FAQ)

Q: Can the 1231AS-H-2R2M=P3 directly replace the SC414MF-2R2 in existing designs?

A: Yes. Both parts share identical inductance values (2.2 µH), tolerance (±20%), saturation current (1.9 A), and shielding characteristics. The substitute part exceeds the minimum current rating requirement (2.55 A vs. 1.78 A) and provides lower DC resistance, making it electrically compatible for direct substitution.

Q: What is the impact of the lower DC resistance in the substitute part?

A: The 1231AS-H-2R2M=P3 exhibits 48 mOhm maximum DC resistance compared to 124 mOhm maximum in the original part. This reduction decreases resistive losses and heat generation, improving overall circuit efficiency without affecting inductance or current handling characteristics.

Q: Are there packaging differences between these parts?

A: Both parts are surface mount components with nonstandard package configurations. The SC414MF-2R2 measures 0.169" L x 0.169" W x 0.059" H (4.30mm x 4.30mm x 1.50mm). The 1231AS-H-2R2M=P3 measures 0.146" L x 0.154" W x 0.071" H (3.70mm x 3.90mm x 1.80mm). Physical dimensions should be verified against PCB layout requirements.

Q: What is the temperature operating range consideration?

A: The original SC414MF-2R2 operates from -40°C to 125°C, while the substitute 1231AS-H-2R2M=P3 operates from -40°C to 85°C. Applications requiring sustained operation above 85°C must retain the original part specification or identify alternative solutions.

Q: Do both parts meet compliance requirements?

A: Yes. Both the SC414MF-2R2 and 1231AS-H-2R2M=P3 are ROHS3 compliant and REACH unaffected, meeting standard environmental and regulatory requirements for electronic component manufacturing and deployment.
