Substitute Part Grouping Explanation

Substitution of the L1008C1R5MDMIT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 1.5 µH
• Package / Case: 1008 (2520 Metric)
• Shielding type: Shielded
• Core material: Ferrite
• Mounting type: Surface Mount
• Tolerance: ±20%

Allowable Parameter Variations:

• Current Rating: Substitute must equal or exceed 1.3 A
• DC Resistance (DCR): Substitute must not exceed 90 mOhm
• Operating Temperature: Substitute range must encompass or exceed -40°C ~ 85°C
• Product Status: Active status preferred for ongoing availability

The Murata Electronics LQM2HPN1R5MG0L meets all mandatory matching parameters and provides improved electrical performance within allowable variation limits.

Parameter Comparison

Engineering Selection Recommendations

The LQM2HPN1R5MG0L from Murata Electronics is a direct functional substitute for the obsolete L1008C1R5MDMIT. Selection of this substitute is supported by the following factors:

Electrical Equivalence: Both components provide identical inductance values (1.5 µH) with matching tolerance specifications (±20%). The substitute exhibits lower DC resistance (88 mOhm versus 90 mOhm maximum), representing improved electrical performance within acceptable limits. Current rating of the substitute (1.5 A) exceeds the original requirement (1.3 A).

Physical Compatibility: Both parts utilize the identical 1008 (2520 Metric) surface mount package with matching footprint dimensions (0.098" L x 0.079" W). The substitute features a lower seated height (0.039" versus 0.079"), which may provide design flexibility for space-constrained applications without compromising compatibility.

Compliance and Availability: The substitute maintains ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing. Moisture sensitivity level remains at MSL 1 (Unlimited). The substitute is classified as active product status, ensuring ongoing availability and manufacturing support, addressing the obsolescence limitation of the original component.

Temperature Performance: The substitute operates across an extended temperature range (-55°C ~ 125°C) that encompasses and exceeds the original specification (-40°C ~ 85°C), providing enhanced thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the LQM2HPN1R5MG0L be used as a direct replacement for the L1008C1R5MDMIT in existing designs?

A: Yes. Both components share identical inductance values, tolerance specifications, package dimensions, and core material composition. The substitute meets or exceeds all electrical performance requirements of the original part.

Q: What are the key differences between these two inductors?

A: The primary differences are product status (substitute is active versus obsolete), current rating (1.5 A versus 1.3 A), DC resistance (88 mOhm versus 90 mOhm), seated height (0.039" versus 0.079"), and operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C). All differences favor the substitute.

Q: Are there any packaging differences that affect assembly?

A: Both parts use the 1008 (2520 Metric) surface mount package with identical footprint dimensions. The substitute features a lower profile (0.039" seated height versus 0.079"), which may require verification of clearance in space-constrained designs but does not affect PCB footprint compatibility.

Q: Does the substitute meet the same compliance requirements?

A: Yes. The LQM2HPN1R5MG0L maintains ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity level, matching the original part's regulatory certifications.

Q: Why is the original part classified as obsolete?

A: The L1008C1R5MDMIT is listed as obsolete by KEMET. The LQM2HPN1R5MG0L from Murata Electronics provides equivalent functionality with active manufacturing status, ensuring long-term availability for new designs and production support.

Q: Can the substitute handle higher current applications?

A: The substitute is rated for 1.5 A maximum current, compared to the original 1.3 A rating. Applications requiring current levels between 1.3 A and 1.5 A can utilize the substitute without derating.

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

A: Lower DC resistance (88 mOhm versus 90 mOhm) reduces resistive losses and heat generation during operation, improving overall circuit efficiency and thermal performance.
