Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806C4R7MDMIT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 4.7 µH
• Package / Case: 0806 (2016 Metric)
• Core material: Ferrite
• Shielding type: Shielded
• Tolerance: ±20%
• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance

Allowable Parameter Variations:

• Current rating must equal or exceed 900 mA
• DC resistance must not exceed 200mOhm
• Mounting type must be Surface Mount
• Moisture sensitivity level must be 1 (Unlimited) or equivalent

The substitute part ASMPH-0806-4R7M-T from Abracon LLC satisfies all mandatory matching criteria and demonstrates superior electrical performance in current rating (1.1 A versus 900 mA) and lower DC resistance (140mOhm versus 200mOhm maximum), making it functionally compatible for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The ASMPH-0806-4R7M-T from Abracon LLC is the qualified substitute for the obsolete L0806C4R7MDMIT. Selection is based on the following engineering factors:

Product Status: The L0806C4R7MDMIT is classified as obsolete, while the ASMPH-0806-4R7M-T maintains active product status, ensuring continued availability and manufacturing support.

Regulatory Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Electrical Performance: The substitute part delivers enhanced electrical characteristics with 1.1 A current rating (22% higher than the original 900 mA specification) and reduced DC resistance of 140mOhm (30% lower than the 200mOhm maximum of the original part). These improvements provide superior thermal performance and reduced power dissipation in circuit applications.

Physical Compatibility: Identical package dimensions (0806 / 2016 Metric), height specifications, and mounting type ensure direct PCB-level compatibility without layout modifications.

Packaging Format: The substitute is supplied in Tape & Reel (TR) format, standard for production environments, compared to the original Cut Tape (CT) & Digi-Reel® packaging.

Frequently Asked Questions (FAQ)

Q: Can the ASMPH-0806-4R7M-T directly replace the L0806C4R7MDMIT without circuit modifications?

A: Yes. Both components share identical inductance values (4.7 µH), tolerance (±20%), package dimensions (0806 / 2016 Metric), and operating temperature ranges (-40°C ~ 85°C). The substitute part meets or exceeds all electrical specifications of the original component.

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

A: The primary differences are product status (obsolete versus active), current rating (900 mA versus 1.1 A), and DC resistance (200mOhm maximum versus 140mOhm). The substitute part provides superior current handling capacity and lower resistance, resulting in reduced power loss and improved thermal characteristics.

Q: Are there any packaging compatibility concerns?

A: No. Both components use identical 0806 (2016 Metric) surface mount packages with matching physical dimensions (0.079" L x 0.063" W, 2.00mm x 1.60mm) and height specifications (0.039" / 1.00mm maximum seated height). PCB footprints are interchangeable.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the L0806C4R7MDMIT and ASMPH-0806-4R7M-T are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. They meet identical environmental and regulatory requirements.

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

A: The ASMPH-0806-4R7M-T exhibits 140mOhm DC resistance compared to the 200mOhm maximum of the original part. This 30% reduction in resistance decreases power dissipation (I²R losses) and improves thermal performance, particularly beneficial in high-current or thermally constrained applications.

Q: Is the substitute part suitable for new design implementations?

A: Yes. The ASMPH-0806-4R7M-T is classified as an active product with full manufacturing support. It is appropriate for both replacement of obsolete components and incorporation into new circuit designs requiring 4.7 µH shielded multilayer inductors in the 0806 package format.
