Parameter Comparison

Engineering Selection Recommendations

The LQM2HPN4R7MG0L from Murata Electronics is a direct substitute for the obsolete L1008C4R7MDMIT. Both components share identical electrical specifications for inductance, current rating, and tolerance. The Murata part offers a lower maximum DC resistance of 138mOhm compared to 150mOhm, which provides improved efficiency characteristics.

The Murata substitute maintains full ROHS3 compliance and Moisture Sensitivity Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The extended operating temperature range of -55°C to 125°C provides additional thermal margin beyond the original KEMET specification of -40°C to 85°C.

The LQM2HPN4R7MG0L maintains active product status with substantial inventory availability, ensuring long-term supply chain continuity for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the LQM2HPN4R7MG0L be used as a direct replacement for the L1008C4R7MDMIT?

A: Yes. Both components share identical inductance values (4.7 µH), current ratings (1.1 A), tolerance specifications (±20%), and package designations (1008 / 2520 Metric). The Murata part meets or exceeds all electrical and mechanical requirements of the KEMET original.

Q: What is the significance of the lower DC resistance in the Murata part?

A: The LQM2HPN4R7MG0L exhibits a maximum DC resistance of 138mOhm compared to 150mOhm in the original part. Lower DC resistance reduces resistive losses and heat generation during operation, improving overall circuit efficiency.

Q: Are there physical dimension differences between these components?

A: Both components use the 1008 (2520 Metric) package. The Murata part has a maximum seated height of 0.039" (1.00mm) compared to 0.079" (2.00mm) for the KEMET part. This reduced height may provide layout advantages in space-constrained applications while maintaining compatibility with standard 1008 footprints.

Q: Does the extended temperature range of the Murata part affect compatibility?

A: No. The extended operating temperature range of -55°C to 125°C in the Murata part is a superset of the original -40°C to 85°C specification. Applications operating within the original temperature range experience no compatibility issues.

Q: Are both parts RoHS compliant?

A: Yes. Both the L1008C4R7MDMIT and LQM2HPN4R7MG0L are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and manufacturing standards.

Q: What is the availability status of each part?

A: The L1008C4R7MDMIT is obsolete with limited remaining inventory. The LQM2HPN4R7MG0L is active with substantial inventory availability, making it the recommended choice for new designs and ongoing production.
