Murata Power Solutions 35112C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 35112C is a 1.1 µH unshielded wirewound inductor rated for 8 A continuous current with a maximum DC resistance of 15mOhm. This component operates across the temperature range of -40°C to 125°C and is housed in a nonstandard surface mount package measuring 6.80mm x 6.80mm x 3.20mm (max height).

The 35112C has reached obsolete product status. Identifying qualified substitute components ensures design continuity and supply chain reliability for applications requiring equivalent inductance and current handling characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 35112C is determined by the following critical parameters:

• Inductance Value: Must match 1.1 µH
• Current Rating: Substitute must support minimum 8 A; higher ratings are acceptable
• DC Resistance: Lower DCR values improve efficiency and reduce thermal dissipation
• Tolerance: ±20% or tighter is acceptable
• Operating Temperature Range: Must encompass or exceed -40°C to 125°C
• Mounting Type: Surface mount configuration required
• Shielding Configuration: Unshielded or shielded variants are both acceptable for substitution purposes

The Würth Elektronik 744314110 qualifies as a substitute based on matching inductance value, exceeding current rating capability, providing superior DC resistance characteristics, and maintaining compatible operating temperature specifications.

Engineering Selection Recommendations

The Würth Elektronik 744314110 is the qualified substitute for the obsolete Murata 35112C. Selection is based on the following factors:

Electrical Compatibility: Both components provide 1.1 µH inductance. The 744314110 delivers superior performance with 15 A current rating versus 8 A, and significantly lower DC resistance of 3.15mOhm compared to 15mOhm maximum.

Temperature Performance: The 744314110 extends the upper operating temperature to 150°C, exceeding the original specification of 125°C.

Compliance & Certifications: The 744314110 carries AEC-Q200 qualification and ROHS3 compliance, supporting automotive and regulated applications. Both components maintain MSL 1 moisture sensitivity and REACH unaffected status.

Product Status: The 744314110 is active production, ensuring long-term availability and supply chain stability compared to the obsolete 35112C.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744314110 directly replace the Murata 35112C?

A: Yes. Both components share identical 1.1 µH inductance and surface mount configuration. The 744314110 exceeds the original current rating and provides lower DC resistance, making it electrically superior for the same application space.

Q: What is the impact of the shielding difference?

A: The 35112C is unshielded while the 744314110 is shielded. Shielding reduces electromagnetic interference emission and susceptibility. For applications sensitive to EMI, the shielded variant may provide improved performance. For applications where shielding is not required, both configurations are functionally equivalent at the specified inductance value.

Q: Are there package dimension considerations?

A: The 35112C measures 6.80mm x 6.80mm x 3.20mm (max height). The 744314110 measures 7.00mm x 6.90mm x 5.00mm (max height). PCB layout verification is required to confirm the increased height does not create clearance conflicts in the target application.

Q: Does the lower DC resistance of the 744314110 affect circuit operation?

A: Lower DC resistance reduces I²R losses and thermal dissipation. This is a performance improvement that does not negatively impact circuit function. Applications operating at or near the 8 A rating will benefit from reduced heat generation.

Q: What compliance certifications apply to the substitute?

A: The 744314110 carries AEC-Q200 qualification for automotive applications and ROHS3 compliance. Both components are REACH unaffected and classified as EAR99 for export control purposes.
