Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-1210H-151K-T is determined by the following critical parameters:

• Inductance value: 150 µH (with ±10% tolerance allowance)
• Package format: 1210 (3225 Metric) surface mount
• Current rating: minimum 140 mA
• DC resistance: electrical performance within acceptable operating margins
• Shielding configuration: unshielded
• Environmental compliance: RoHS3 compliance required

The Murata Power Solutions 82154C meets these substitution criteria as an active product with identical inductance specification, compatible package dimensions, and equivalent electrical ratings within the defined tolerance band.

Parameter Comparison

Engineering Selection Recommendations

The 82154C from Murata Power Solutions is the designated substitute for the obsolete AISC-1210H-151K-T. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part is currently in active production with substantial inventory availability (10,312 pcs), providing supply chain continuity.

The 82154C exhibits lower DC resistance (5.9Ohm vs. 8.32Ohm), which reduces power dissipation in the inductor. The current rating of 130 mA is marginally lower than the original 140 mA specification; circuit designs operating at or near the 140 mA threshold require verification that the 130 mA rating remains acceptable for the intended application. The extended operating temperature range (-40°C to 85°C) of the substitute provides additional environmental margin compared to the original part (-25°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can the 82154C be used as a direct replacement for the AISC-1210H-151K-T?

A: The 82154C is functionally equivalent for applications where the 130 mA current rating is sufficient. Both parts share identical inductance values, package dimensions, and tolerance specifications. The lower DC resistance of the substitute is generally advantageous for thermal performance.

Q: What is the significance of the 10 mA difference in current rating?

A: The AISC-1210H-151K-T is rated for 140 mA maximum current, while the 82154C is rated for 130 mA. Applications operating below 130 mA experience no constraint. Designs requiring the full 140 mA rating must evaluate whether the 10 mA reduction impacts circuit performance or thermal margins.

Q: Are the physical dimensions compatible?

A: Both parts use the 1210 (3225 Metric) package format. The AISC-1210H-151K-T has a seated height of 2.50mm, while the 82154C has a seated height of 2.30mm. This 0.20mm difference is within typical PCB assembly tolerances and does not affect mechanical compatibility.

Q: What are the compliance and supply considerations?

A: The AISC-1210H-151K-T is obsolete with limited remaining inventory. The 82154C is an active product with robust supply availability, ensuring long-term procurement reliability. Both parts maintain ROHS3 compliance and REACH unaffected status.

Q: How do the DC resistance values affect circuit performance?

A: The 82154C exhibits 5.9Ohm maximum DC resistance compared to 8.32Ohm for the original part. Lower DC resistance reduces I²R losses and heat generation, which is beneficial for thermal management. Circuit designs should account for this difference if precise impedance matching is required.
