Key Parameters

Substitute Part Grouping Explanation

The IRF36ER680K qualifies as a substitute based on the following criteria:

Matching Parameters:

• Inductance value: 68 µH (identical)
• Package type: Axial through-hole (identical)
• Manufacturer: Vishay Dale (same manufacturer)

Allowable Variations:

• Current rating: IRF36ER680K rated at 306 mA exceeds the 170 mA requirement of IMS05EB680K, providing margin for circuit operation
• DC resistance: IRF36ER680K at 1.47 Ohm maximum is lower than the 2.7 Ohm maximum of IMS05EB680K, reducing power dissipation
• Shielding: IRF36ER680K is unshielded, whereas IMS05EB680K is shielded; this difference requires evaluation based on electromagnetic interference considerations in the specific application

Parameter Comparison

Engineering Selection Recommendations

Selection between IMS05EB680K and IRF36ER680K depends on application-specific requirements:

The IMS05EB680K provides shielded construction, suitable for applications requiring electromagnetic interference suppression. The IRF36ER680K offers higher current capacity (306 mA versus 170 mA) and lower DC resistance (1.47 Ohm versus 2.7 Ohm), resulting in reduced thermal dissipation and improved efficiency in high-current applications.

Both components maintain identical inductance values and axial through-hole packaging, ensuring mechanical and electrical compatibility at the circuit board level. The choice between shielded and unshielded construction must be determined by the electromagnetic environment and noise immunity requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can IRF36ER680K replace IMS05EB680K in all applications?

A: Both parts share identical inductance values (68 µH) and package types (axial through-hole). The IRF36ER680K has higher current rating and lower DC resistance. The primary difference is shielding: IMS05EB680K is shielded while IRF36ER680K is unshielded. Substitution is valid where electromagnetic interference is not a design constraint.

Q: What is the significance of the current rating difference?

A: IMS05EB680K is rated for 170 mA maximum current, while IRF36ER680K is rated for 306 mA. The higher rating of IRF36ER680K provides operational margin in circuits drawing up to 170 mA, with no derating required.

Q: How does DC resistance affect circuit performance?

A: DC resistance determines power dissipation in the inductor. IRF36ER680K at 1.47 Ohm maximum dissipates less power than IMS05EB680K at 2.7 Ohm maximum when carrying the same current, resulting in lower heat generation and improved thermal performance.

Q: When should shielding be considered in the selection decision?

A: Shielded inductors (IMS05EB680K) reduce radiated electromagnetic interference and are preferred in noise-sensitive applications. Unshielded inductors (IRF36ER680K) are suitable for applications where EMI is not a primary concern and where the improved electrical characteristics are beneficial.

Q: Are both parts from the same manufacturer?

A: Yes, both IMS05EB680K and IRF36ER680K are manufactured by Vishay Dale, ensuring consistent quality and reliability standards across both components.
