Key Parameters

Substitute Part Grouping Explanation

Substitution of the L1008C1R0MDMIT is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Inductance value: 1 µH (exact match required)
• Inductance tolerance: ±20% (matching specification)
• Operating temperature range: -40°C to 85°C (minimum requirement)
• Shielding type: Shielded (electromagnetic containment requirement)
• Core material: Ferrite (performance characteristic)

Mechanical Compatibility Requirements:

• Package / Case: 1008 (2520 Metric) (PCB footprint compatibility)
• Mounting type: Surface Mount (assembly process compatibility)
• Physical dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm) (board layout constraint)

Performance Enhancement Criteria:

• Current rating: Substitute must equal or exceed 1.4 A
• DC resistance: Substitute should not exceed 80 mOhm Max (thermal and efficiency consideration)

Regulatory Compliance:

• RoHS3 compliance (environmental requirement)
• REACH unaffected status (chemical regulation requirement)

The LQM2HPN1R0MJHL from Murata Electronics qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering improved performance characteristics.

Engineering Selection Recommendations

The LQM2HPN1R0MJHL from Murata Electronics is a qualified substitute for the obsolete L1008C1R0MDMIT. Selection is based on the following engineering factors:

Electrical Equivalence: All critical electrical parameters match the original specification. The 1 µH inductance value, ±20% tolerance, and operating temperature range of -40°C to 85°C are identical. The substitute component exceeds the original current rating (2.3 A versus 1.4 A) and provides superior DC resistance performance (63 mOhm Max versus 80 mOhm Max), resulting in reduced thermal dissipation and improved efficiency in the application circuit.

Mechanical Compatibility: The 1008 (2520 Metric) package footprint, surface mount configuration, and planar dimensions (0.098" L x 0.079" W) are identical to the original part. The substitute exhibits a lower seated height (0.047" versus 0.079"), which presents no compatibility issue for standard PCB assembly processes and may provide clearance advantages in space-constrained layouts.

Regulatory and Compliance Status: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and chemical regulatory requirements. The substitute is classified as active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Packaging Consideration: The original part is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the substitute is supplied in Tape & Reel (TR) format. Both packaging formats are standard for surface mount component assembly and present no functional or compatibility constraints.

Frequently Asked Questions (FAQ)

Q: Can the LQM2HPN1R0MJHL directly replace the L1008C1R0MDMIT in existing designs?

A: Yes. The substitute component matches all critical electrical and mechanical parameters. Identical inductance value (1 µH), tolerance (±20%), operating temperature range (-40°C to 85°C), package footprint (1008 / 2520 Metric), and shielding configuration ensure direct compatibility. The substitute's improved current rating and reduced DC resistance provide performance enhancement without circuit modification.

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

A: The primary differences are product status and performance characteristics. The L1008C1R0MDMIT is obsolete, while the LQM2HPN1R0MJHL is active production. The substitute offers higher current capacity (2.3 A versus 1.4 A), lower DC resistance (63 mOhm versus 80 mOhm), and lower seated height (0.047" versus 0.079"). These differences represent performance improvements with no negative impact on circuit function.

Q: Are there any PCB layout considerations when substituting these parts?

A: No layout modifications are required. Both components use the identical 1008 (2520 Metric) package with matching planar dimensions (0.098" L x 0.079" W). The substitute's reduced height (0.047" versus 0.079") may provide additional clearance in space-constrained applications but does not require design changes.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both the L1008C1R0MDMIT and LQM2HPN1R0MJHL are ROHS3 compliant and REACH unaffected. They satisfy identical environmental and chemical regulatory standards for commercial and industrial applications.

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

A: Lower DC resistance (63 mOhm versus 80 mOhm) reduces resistive losses and heat generation during operation. This characteristic improves power efficiency and thermal performance in the application circuit, particularly in high-frequency switching applications where inductor losses contribute to overall system efficiency.

Q: Is the substitute part available in the same packaging format?

A: The original part is supplied in Cut Tape (CT) & Digi-Reel® format, while the substitute is supplied in Tape & Reel (TR) format. Both are standard surface mount packaging formats compatible with automated assembly equipment. Packaging format selection depends on production volume and assembly process requirements rather than component function.

Q: What is the moisture sensitivity level for both components?

A: Both components are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints. These parts do not require special moisture control during storage, handling, or assembly, simplifying supply chain management and manufacturing processes.
