Key Parameters

Substitute Part Grouping Explanation

Substitution of the DFE201610R-H-R47M=P2 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 470 nH (fixed specification)
• Package Type: 0806 (2016 Metric) surface mount form factor
• Core Configuration: Shielded drum core wirewound construction with iron powder core material
• Operating Temperature Range: -40°C to 125°C
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The substitute part DFE201610P-R47M=P2 maintains identical inductance, package, core type, and operating temperature specifications. Variations in current rating and DC resistance are permissible when the substitute part meets or exceeds the electrical performance requirements of the original design.

Parameter Comparison

Engineering Selection Recommendations

The DFE201610P-R47M=P2 is the direct substitute for the obsolete DFE201610R-H-R47M=P2. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility. The substitute part is currently in active production status with established supply availability, addressing the obsolescence of the original component.

The substitute part exceeds the current rating specification (4 A versus 3.8 A) and maintains identical inductance and package specifications. The increased DC resistance (40 mOhm Max versus 26 mOhm Max) represents the primary electrical difference and must be evaluated within the context of the specific circuit application to determine thermal and performance impact.

Frequently Asked Questions (FAQ)

Q: Can DFE201610P-R47M=P2 be used as a direct replacement for DFE201610R-H-R47M=P2?

A: Yes. Both parts share identical inductance (470 nH), tolerance (±20%), package (0806 2016 Metric), core type (shielded drum core wirewound), core material (iron powder), operating temperature range (-40°C to 125°C), and compliance certifications (ROHS3, MSL 1). The substitute part is actively manufactured and available.

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

A: The substitute part has a maximum DC resistance of 40 mOhm compared to 26 mOhm in the original part. This difference will result in increased resistive losses during operation. Circuit designers must evaluate whether this increased resistance is acceptable for their specific application, particularly in high-current or low-noise-sensitive circuits.

Q: Are the package dimensions identical between the two parts?

A: Yes. Both parts use the 0806 (2016 Metric) surface mount package with identical dimensions of 0.079" L x 0.063" W (2.00mm x 1.60mm) and a maximum seated height of 0.039" (1.00mm). PCB layout and assembly processes require no modification.

Q: What is the current rating difference, and does it affect substitution?

A: The substitute part is rated for 4 A continuous current compared to 3.8 A for the original part. This represents an improvement in current handling capability and does not restrict substitution in applications designed for the original 3.8 A rating.

Q: Are both parts RoHS compliant?

A: Yes. Both DFE201610R-H-R47M=P2 and DFE201610P-R47M=P2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring compatibility with modern manufacturing and environmental standards.
