Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMP5022-223M is permissible when the alternative component meets the following critical parameters:

• Inductance value of 220 µH within acceptable tolerance range
• Current rating sufficient for application requirements (minimum 1.1 A)
• DC resistance within acceptable operating limits
• Ferrite core material for equivalent frequency response
• Unshielded configuration to maintain EMI characteristics
• Surface mount capability with compatible footprint dimensions
• Operating temperature range covering -40°C minimum to 125°C
• Moisture sensitivity level MSL 1 or equivalent

The SDR1806-221KL from Bourns Inc. satisfies these substitution criteria as a drum core, wirewound inductor with matching inductance, compatible current ratings, and equivalent thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The SDR1806-221KL qualifies as a functional equivalent based on the following criteria:

• Both components maintain Active product status with confirmed inventory availability
• Electrical specifications align within acceptable engineering tolerances for 220 µH inductors
• RoHS3 compliance of the substitute part meets modern regulatory requirements
• Identical moisture sensitivity classification ensures equivalent handling and storage protocols
• Surface mount configuration and nonstandard package types support direct PCB integration
• Ferrite core construction provides equivalent frequency response characteristics

Selection between the main part and substitute should account for application-specific current requirements. The SMP5022-223M provides 1.2 A rated current versus 1.1 A for the SDR1806-221KL. Applications operating near maximum current specifications should verify margin adequacy with the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the SDR1806-221KL directly replace the SMP5022-223M in all applications?

A: Direct replacement is permissible when application current requirements do not exceed 1.1 A continuous operation. The substitute component has slightly lower current and saturation ratings. Verify your circuit's maximum operating current against the substitute's 1.1 A rating before implementation.

Q: What are the dimensional differences between these inductors?

A: The SMP5022-223M measures 19.04 mm (L) x 15.74 mm (W) x 7.11 mm (H), while the SDR1806-221KL measures 18.30 mm (L) x 14.00 mm (W) x 6.90 mm (H). Both are nonstandard packages. Verify PCB footprint compatibility and clearance requirements before substitution.

Q: How do the DC resistance values compare?

A: The SMP5022-223M specifies 380 mOhm maximum DC resistance, while the SDR1806-221KL specifies 420 mOhm maximum. The substitute has 40 mOhm higher resistance. For applications sensitive to resistive losses, calculate power dissipation impact at your operating current.

Q: Are there temperature range limitations with the substitute?

A: The SMP5022-223M operates from -55°C to 125°C, while the SDR1806-221KL operates from -40°C to 125°C. If your application requires operation below -40°C, the original part is required. For standard industrial temperature ranges, both components are compatible.

Q: What is the tolerance difference between these parts?

A: The SMP5022-223M has ±20% inductance tolerance, while the SDR1806-221KL has ±10% tolerance. The substitute provides tighter inductance control, which may benefit applications requiring precise inductance values.

Q: Are both components RoHS compliant?

A: The SMP5022-223M is not applicable for RoHS classification. The SDR1806-221KL is RoHS3 compliant. Verify your application's regulatory requirements before selecting the substitute.
