Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-1210H-221K-T is determined by the following critical parameters:

• Inductance value: 220 µH (±10% tolerance)
• Current rating: minimum 100 mA
• Package format: 1210 (3225 Metric) surface mount
• Shielding configuration: unshielded
• DC resistance: must not exceed application-specific limits
• Regulatory compliance: ROHS3 and REACH status alignment

The substitute part 82224C meets these core electrical and mechanical requirements while offering improved performance characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

The 82224C from Murata Power Solutions Inc. is an active production equivalent for the obsolete AISC-1210H-221K-T. Both components maintain identical inductance values, current ratings, package formats, and regulatory compliance certifications. The 82224C offers improved DC resistance performance (8Ohm maximum versus 14.4Ohm), lower self-resonant frequency, and an extended lower operating temperature limit (-40°C versus -25°C). Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment. The active production status of the 82224C provides supply chain continuity and long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can the 82224C directly replace the AISC-1210H-221K-T in existing designs?

A: Yes. Both components share identical inductance (220 µH), current rating (100 mA), package format (1210), and tolerance specifications (±10%). The 82224C features lower DC resistance and extended temperature range, making it functionally compatible for direct substitution.

Q: What is the significance of the lower DC resistance in the 82224C?

A: The 82224C exhibits 8Ohm maximum DC resistance compared to 14.4Ohm in the AISC-1210H-221K-T. Lower DC resistance reduces power dissipation and heat generation in the inductor, which may improve circuit efficiency and thermal performance depending on application current levels.

Q: Are there packaging or mounting differences between these parts?

A: No. Both components use the 1210 (3225 Metric) surface mount package with identical footprint dimensions and mounting requirements. PCB layout and assembly processes remain unchanged.

Q: Why is the AISC-1210H-221K-T classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. The 82224C represents the current production alternative that maintains electrical and mechanical compatibility while offering improved performance characteristics.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AISC-1210H-221K-T and 82224C are ROHS3 compliant and REACH unaffected, ensuring compliance with current environmental and hazardous substance regulations.
