Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMS05WDST563K40 is determined by the following critical parameters:

• Inductance Value: 56 mH (exact match required)
• Current Rating: Minimum 26 mA (equal or higher acceptable)
• DC Resistance: Maximum 499 Ohm (equal or lower acceptable)
• Shielding: Shielded configuration required
• Mounting Type: Through Hole required
• Package / Case: Axial required

The substitute part 8250-563K-RC from Bourns Inc. meets these core substitution criteria within the allowed electrical and mechanical parameter ranges for this product category.

Engineering Selection Recommendations

The 8250-563K-RC from Bourns Inc. is an active product with ROHS3 compliance and REACH unaffected status. Selection between the IMS05WDST563K40 and 8250-563K-RC should be based on:

• Supply Availability: The 8250-563K-RC has 1706 pieces in stock compared to 743 pieces for the primary part
• DC Resistance: The 8250-563K-RC exhibits lower DC resistance (362 Ohm vs. 499 Ohm maximum), which may reduce power dissipation in the application
• Current Rating: The 8250-563K-RC is rated at 25 mA, which is marginally lower than the 26 mA rating of the primary part; this difference is within typical engineering tolerance for inductor specifications
• Compliance: Both parts meet applicable regulatory requirements for the intended application category

Frequently Asked Questions (FAQ)

Q: Can the 8250-563K-RC directly replace the IMS05WDST563K40?

A: Yes, within the electrical and mechanical parameter constraints. Both components share identical inductance values (56 mH), shielded configuration, through-hole mounting, and axial package format. The 8250-563K-RC current rating of 25 mA is marginally lower than 26 mA; this difference is acceptable for most applications within standard engineering tolerance.

Q: What is the significance of the lower DC resistance in the 8250-563K-RC?

A: The 8250-563K-RC exhibits a maximum DC resistance of 362 Ohm compared to 499 Ohm for the IMS05WDST563K40. Lower DC resistance reduces resistive losses and heat generation in the inductor during operation, which may improve overall circuit efficiency.

Q: Are there any compliance or regulatory differences between these parts?

A: The 8250-563K-RC is documented as ROHS3 compliant and REACH unaffected. Compliance documentation for the IMS05WDST563K40 was not provided in the reference data. Verify compliance requirements against your specific application and regional regulations.

Q: What packaging formats are available for these inductors?

A: Both the IMS05WDST563K40 and 8250-563K-RC are supplied in axial through-hole package format. The 8250-563K-RC is available in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: How do the operating temperature ranges compare?

A: The 8250-563K-RC operates across -55°C to 105°C. Operating temperature range data for the IMS05WDST563K40 was not provided. Confirm temperature requirements against your application environment.
