• Physical dimensions: 0.079" L × 0.063" W (2.00 mm × 1.60 mm)
• Maximum seated height: 0.071" (1.80 mm)
• Mounting type: Surface mount

Material & Construction:

• Core material: Ferrite
• Core type: Drum core, wirewound
• Shielding: Unshielded

Compliance & Environmental:

Substitute parts must satisfy all parameters within the specified tolerances and ratings to ensure functional and physical compatibility in the original application.

Parameter Comparison

Engineering Selection Recommendations

The CBC2016T4R7M manufactured by Taiyo Yuden serves as a direct functional equivalent to the obsolete L0806C4R7MDWIT. Both components share identical electrical specifications for inductance, current rating, saturation current, and self resonant frequency. Physical compatibility is confirmed through matching package designation, dimensions, and mounting type.

The primary distinction between the two parts is DC resistance: the L0806C4R7MDWIT specifies 370 mOhm, while the CBC2016T4R7M specifies 481 mOhm maximum. This difference of 111 mOhm represents approximately 30% higher resistance in the substitute part. Applications sensitive to resistive losses or thermal dissipation must evaluate this parameter against circuit requirements.

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical operating temperature specifications. The CBC2016T4R7M carries a "Not For New Designs" status, indicating limited long-term availability. For new designs, alternative suppliers should be evaluated; for legacy system maintenance, the CBC2016T4R7M provides immediate functional replacement capability.

Frequently Asked Questions (FAQ)

Q: Can the CBC2016T4R7M directly replace the L0806C4R7MDWIT in existing assemblies?

A: Yes, the CBC2016T4R7M provides direct physical and electrical replacement. Both components occupy identical 0806 (2016 Metric) package space with matching lead configurations. Electrical parameters including inductance, current rating, and saturation current are equivalent. The higher DC resistance of the substitute (481 mOhm vs. 370 mOhm) must be evaluated for applications where resistive losses impact performance.

Q: What is the significance of the DC resistance difference between these parts?

A: The CBC2016T4R7M exhibits 111 mOhm higher DC resistance than the L0806C4R7MDWIT. In circuits carrying the rated 530 mA current, this results in approximately 59 mW additional power dissipation in the substitute part. Applications operating near thermal limits or requiring minimal resistive losses should verify compatibility through circuit simulation or testing.

Q: Are both parts suitable for new product designs?

A: The L0806C4R7MDWIT carries Obsolete status and is unsuitable for new designs. The CBC2016T4R7M carries "Not For New Designs" status, indicating limited future availability. For new product development, alternative 4.7 µH inductors in the 0806 package from active manufacturers should be identified and qualified.

Q: Do these parts require different PCB footprints or assembly processes?

A: No. Both components use identical 0806 (2016 Metric) package specifications with matching physical dimensions of 2.00 mm × 1.60 mm and maximum seated height of 1.80 mm. Standard surface mount assembly processes and PCB footprints designed for 0806 inductors accommodate both parts without modification.

Q: What compliance certifications apply to both parts?

A: Both the L0806C4R7MDWIT and CBC2016T4R7M are ROHS3 compliant and REACH unaffected. Both carry moisture sensitivity level 1 (unlimited), indicating no special moisture control requirements during storage or handling. Operating temperature specifications are identical at -40°C to 105°C.
