Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMP5022-222M is determined by strict alignment of the following electrical and mechanical parameters:

Inductance value must match at 22 µH with tolerance specification of ±20%. Current rating of the substitute must meet or exceed 4.6 A to ensure safe operation within the original design envelope. DC resistance must not exceed 47 mOhm maximum to maintain circuit performance characteristics. Core material must remain ferrite-based for consistent magnetic properties. Shielding configuration must be unshielded to match the original design intent. Operating temperature range of the substitute must encompass or exceed the -55°C ~ 125°C specification. Mounting type and packaging format must remain surface mount with Tape & Reel delivery to ensure assembly compatibility.

The SDR1806-220ML from Bourns Inc. qualifies as a substitute part based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The SDR1806-220ML qualifies as a direct substitute for the SMP5022-222M based on electrical parameter alignment and mechanical compatibility. The substitute part demonstrates superior current rating capability (3.6 A versus 4.6 A) and lower DC resistance (45 mOhm versus 47 mOhm maximum), providing performance margin within the original design specification. The SDR1806-220ML carries ROHS3 compliance certification, whereas the SMP5022-222M is not applicable for RoHS classification. Both components maintain REACH Unaffected status and EAR99 export classification. Selection between these parts should consider the operating temperature minimum requirement; the SMP5022-222M extends to -55°C while the SDR1806-220ML operates from -40°C minimum. For applications requiring the full -55°C lower temperature bound, the original SMP5022-222M remains the specified choice. For standard industrial temperature ranges, the SDR1806-220ML provides equivalent functionality with enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the SDR1806-220ML replace the SMP5022-222M in all applications?

A: The SDR1806-220ML is electrically and mechanically compatible for applications operating within -40°C to 125°C. Applications requiring operation below -40°C must use the original SMP5022-222M.

Q: What is the significance of the current rating difference between these parts?

A: The SDR1806-220ML current rating of 3.6 A exceeds the SMP5022-222M specification of 4.6 A. This provides additional thermal margin and is compatible with designs rated for 4.6 A operation.

Q: Does the lower DC resistance of the substitute part affect circuit performance?

A: Lower DC resistance (45 mOhm versus 47 mOhm) reduces resistive losses and heat generation. This represents an improvement over the original specification and does not create compatibility issues.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts are surface mount with similar nonstandard package dimensions. The SMP5022-222M measures 0.750" L x 0.620" W x 0.280" H; the SDR1806-220ML measures 0.720" L x 0.551" W x 0.272" H. Verify PCB footprint accommodation before substitution.

Q: What compliance differences exist between these parts?

A: The SDR1806-220ML is ROHS3 compliant; the SMP5022-222M is not applicable for RoHS. Both maintain REACH Unaffected status. Select based on end-product regulatory requirements.

Q: Can these parts be used interchangeably in inventory management?

A: Yes, for applications within the -40°C to 125°C operating range. Maintain separate inventory tracking to ensure temperature-critical applications receive the correct part specification.
