Murata Power Solutions 41330C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 41330C is a 33 µH unshielded toroidal inductor rated for 2.7 A with a maximum DC resistance of 38 mOhm, designed for surface mount applications in nonstandard packaging. This component operates across the temperature range of -40°C to 85°C and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 41330C is determined by the following critical parameters:

• Inductance tolerance: The substitute must maintain inductance within acceptable circuit operating margins. The 41330C specifies 33 µH; the PL8606NL provides 32.8 µH (±10% tolerance), representing a 0.6% deviation suitable for most applications.
• Current rating: The substitute must support the required circuit current. The 41330C is rated for 2.7 A; the PL8606NL is rated for 2.2 A, representing a 18.5% reduction in current capacity.
• DC resistance: The substitute's DCR must not introduce excessive losses. The 41330C specifies 38 mOhm Max; the PL8606NL specifies 101 mOhm Max, representing a 166% increase in resistance.
• Temperature range: The substitute must operate within the required thermal environment. The 41330C operates -40°C to 85°C; the PL8606NL operates -40°C to 130°C, providing extended high-temperature capability.
• Compliance certifications: Both parts must meet applicable regulatory requirements (RoHS, REACH, ECCN).

Parameter Comparison

Engineering Selection Recommendations

The PL8606NL from iNRCORE, LLC is designated as the manufacturer-recommended substitute for the 41330C. Selection of this substitute requires evaluation against specific circuit requirements:

Current capacity consideration: The PL8606NL current rating of 2.2 A is lower than the 41330C rating of 2.7 A. Applications operating at or above 2.2 A must verify that circuit current does not exceed the substitute's rating to prevent thermal stress and inductor saturation.

DC resistance impact: The PL8606NL exhibits significantly higher DC resistance (101 mOhm Max versus 38 mOhm Max). This 166% increase will result in higher I²R losses and elevated operating temperature. Circuit designs sensitive to inductor losses or thermal dissipation must account for this parameter change.

Temperature range advantage: The PL8606NL supports operation to 130°C, exceeding the 41330C maximum of 85°C. This extended range provides thermal margin for applications in elevated ambient or high-power environments.

Compliance status: Both parts maintain RoHS compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The PL8606NL carries ROHS3 certification, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the PL8606NL directly replace the 41330C in all applications?

A: Direct replacement requires verification of three critical parameters: (1) circuit current must not exceed 2.2 A; (2) circuit design must tolerate the increased 101 mOhm DCR and associated I²R losses; (3) thermal design must accommodate higher operating temperature from increased losses. If all three conditions are met, substitution is viable.

Q: What is the inductance difference between these parts, and does it matter?

A: The PL8606NL inductance is 32.8 µH with ±10% tolerance, compared to the 41330C at 33 µH. The -0.6% deviation falls within typical circuit tolerance margins for most applications. However, circuits with tight inductance specifications or resonant frequency requirements should verify compatibility through simulation or testing.

Q: Why is the DC resistance so much higher on the PL8606NL?

A: The PL8606NL exhibits 101 mOhm Max DCR compared to 38 mOhm Max on the 41330C. This difference reflects different core materials, winding geometry, or manufacturing processes between manufacturers. Higher DCR increases power dissipation proportionally to I². Applications operating near maximum current ratings will experience measurable temperature rise.

Q: Are there any packaging or mounting differences?

A: Both parts are surface mount toroidal inductors in nonstandard packaging. The 41330C measures 0.690" L × 0.660" W × 0.390" H; the PL8606NL measures 0.625" L × 0.525" W × 0.320" H. The PL8606NL is physically smaller. PCB layout and thermal management designs must account for these dimensional changes.

Q: What compliance certifications apply to both parts?

A: Both the 41330C and PL8606NL are RoHS compliant, REACH unaffected, and classified as EAR99 for export control purposes. The PL8606NL carries ROHS3 certification. Both maintain MSL 1 (unlimited) moisture sensitivity rating, requiring no special storage or handling beyond standard ESD precautions.

Q: Is the PL8606NL suitable for high-temperature applications?

A: The PL8606NL operates to 130°C maximum, compared to the 41330C at 85°C. This 45°C extended range provides thermal margin. However, the higher DCR will generate additional heat at rated current. Thermal analysis should confirm that the combination of ambient temperature, circuit current, and inductor losses does not exceed component or system thermal limits.
