Key Parameters

Substitute Part Grouping Explanation

Substitution of the DFE201612E-R68M=P2 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 680 nH
• Inductance tolerance: ±20%
• Current rating: 3.5 A minimum
• Saturation current (Isat): 4.3 A minimum
• DC resistance: 33 mOhm maximum
• Shielding requirement: Shielded

Mechanical Parameters:

• Package type: 0806 (2016 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.079" L x 0.063" W (2.00 mm x 1.60 mm)
• Height seated (max): 0.047" (1.20 mm)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 125°C
• RoHS3 compliance
• MSL Level 1 (Unlimited)
• REACH Unaffected status

A substitute part must satisfy all electrical specifications, fit within the defined mechanical envelope, and maintain the same compliance certifications. Parts that deviate from any of these parameters are not considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The DFE201612E-R68M=P2 is an Active product with full RoHS3 compliance and REACH Unaffected status, making it suitable for applications requiring regulatory adherence in restricted substance directives. The MSL Level 1 (Unlimited) rating indicates no moisture sensitivity constraints during storage or handling.

When selecting this component or its equivalents, confirm that the application requirements align with the specified electrical parameters: 680 nH inductance at ±20% tolerance, 3.5 A continuous current rating, and 4.3 A saturation current. The 33 mOhm maximum DC resistance is a critical parameter for power loss calculations in high-current applications.

The shielded wirewound construction with metal core provides electromagnetic interference (EMI) containment suitable for noise-sensitive circuits. The 0806 (2016 Metric) surface mount package is standard for compact PCB layouts with 2.00 mm length and 1.60 mm width constraints.

Component selection should prioritize parts with identical electrical specifications, matching package dimensions, and equivalent compliance certifications to ensure direct interchangeability without circuit redesign or re-qualification.

Frequently Asked Questions (FAQ)

Q: What makes DFE201612E-R68M=P2 a direct substitute for itself?

A: The DFE201612E-R68M=P2 is identical across all electrical, mechanical, and compliance parameters. It maintains the same 680 nH inductance value, 3.5 A current rating, 33 mOhm maximum DC resistance, shielded metal-core construction, 0806 (2016 Metric) package dimensions, RoHS3 compliance, and MSL Level 1 rating.

Q: Are there any differences in the substitute part listed?

A: No. The substitute part listed is the DFE201612E-R68M=P2, which is identical to the main part in all specifications. There are no parametric differences.

Q: What are the critical parameters that must match for substitution?

A: Critical parameters include inductance (680 nH ±20%), current rating (3.5 A minimum), saturation current (4.3 A minimum), DC resistance (33 mOhm maximum), shielding type (shielded), core material (metal), package type (0806 / 2016 Metric), mounting type (surface mount), physical dimensions (0.079" L x 0.063" W / 2.00 mm x 1.60 mm), height (0.047" / 1.20 mm maximum), operating temperature range (-40°C to 125°C), and compliance certifications (RoHS3, REACH Unaffected, MSL Level 1).

Q: Can this inductor be used in applications requiring lower current ratings?

A: Yes. The DFE201612E-R68M=P2 is rated for 3.5 A continuous current and 4.3 A saturation current. Applications requiring lower current levels operate within the component's specifications and thermal limits.

Q: What is the significance of the 0806 (2016 Metric) package designation?

A: The 0806 package is a surface mount inductor package with dimensions of 0.079" length by 0.063" width (2.00 mm x 1.60 mm) and a maximum seated height of 0.047" (1.20 mm). This standardized package ensures compatibility with automated assembly equipment and PCB layout constraints.

Q: Does the ±20% inductance tolerance affect circuit performance?

A: The ±20% tolerance defines the acceptable range of inductance values from the nominal 680 nH specification. Circuit designs must account for this tolerance range in frequency response, impedance matching, and filtering calculations.

Q: What does MSL Level 1 (Unlimited) mean for component handling?

A: MSL Level 1 indicates unlimited moisture sensitivity. The component requires no special moisture control during storage, handling, or assembly processes. Standard warehouse conditions are acceptable.

Q: Is the DFE201612E-R68M=P2 suitable for high-frequency applications?

A: The inductance is specified at 1 MHz test frequency. Applications operating at or near 1 MHz can use the published inductance value directly. For frequencies significantly above or below 1 MHz, frequency-dependent behavior should be evaluated using the component's frequency response characteristics.

Q: What compliance certifications does this inductor carry?

A: The DFE201612E-R68M=P2 is RoHS3 compliant, REACH Unaffected, and carries MSL Level 1 (Unlimited) moisture sensitivity rating. These certifications confirm compliance with European Union restricted substance directives and environmental regulations.
