SMP5022-104M Equivalent & Substitute Parts

Part Overview

The SMP5022-104M is a 1 mH unshielded molded inductor manufactured by Gowanda Electronics, designed for surface mount applications. This component features a ferrite core with a current rating of 560 mA and a maximum DC resistance of 1.8Ohm. The part is currently active in production with 825 pieces available in new original stock.

Equivalent and substitute parts are identified when component availability changes, supply chain disruptions occur, or design flexibility allows for alternative sourcing while maintaining electrical and mechanical compatibility within specified tolerances.

Substitute Part Grouping Explanation

Substitution of the SMP5022-104M is based on the following critical parameters:

• Inductance value: 1 mH (within tolerance specifications)
• Current rating: Minimum 500 mA (substitute must support primary circuit current requirements)
• DC resistance: 1.8Ohm maximum (electrical performance and thermal characteristics)
• Core material: Ferrite (electromagnetic properties)
• Shielding configuration: Unshielded (EMI/RFI performance profile)
• Mounting type: Surface mount (assembly compatibility)
• Operating temperature range: Overlap with -55°C ~ 125°C specification
• Package form factor: Nonstandard surface mount dimensions within acceptable mechanical envelope

The SDR1806-102KL from Bourns Inc. qualifies as a substitute based on matching inductance, core material, shielding type, and surface mount configuration, with current rating and DC resistance specifications that satisfy the primary part's electrical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the SMP5022-104M and SDR1806-102KL are active production components with unlimited moisture sensitivity ratings and REACH unaffected status. The SDR1806-102KL carries ROHS3 compliance, which may be required for applications subject to RoHS regulations.

The SDR1806-102KL exhibits tighter inductance tolerance (±10% versus ±20%), which provides improved consistency in circuit performance. However, the current rating of 500 mA is 60 mA lower than the SMP5022-104M's 560 mA rating, and saturation current is 0.2A lower. Circuit design must confirm that operating current remains within the 500 mA specification of the substitute part.

The operating temperature range of the SDR1806-102KL extends to -40°C minimum, which is 15°C higher than the SMP5022-104M. Applications requiring operation below -40°C must retain the original SMP5022-104M specification.

Frequently Asked Questions (FAQ)

Q: Can the SDR1806-102KL directly replace the SMP5022-104M in all applications?

A: Substitution is valid only when circuit operating current does not exceed 500 mA and minimum operating temperature is not below -40°C. Both parts share identical inductance value, DC resistance, core material, and shielding configuration. Verify circuit current requirements before substitution.

Q: What is the significance of the inductance tolerance difference?

A: The SMP5022-104M specifies ±20% tolerance while the SDR1806-102KL specifies ±10% tolerance. Tighter tolerance in the substitute part results in more consistent inductance values across production batches, which may improve circuit performance stability. Applications with strict inductance requirements benefit from the substitute's tighter specification.

Q: Are there packaging differences between these parts?

A: Both parts are nonstandard surface mount packages. The SMP5022-104M measures 0.750" L x 0.620" W x 0.280" H (19.04mm x 15.74mm x 7.11mm). The SDR1806-102KL measures 0.720" L x 0.551" W x 0.272" H (18.30mm x 14.00mm x 6.90mm). Dimensional differences are minor; verify PCB layout and component placement clearances before substitution.

Q: What compliance certifications apply to each part?

A: The SMP5022-104M carries ECCN EAR99 and HTSUS 8504.50.8000 classifications. The SDR1806-102KL is ROHS3 compliant with ECCN EAR99 and HTSUS 8504.50.4000 classifications. Applications requiring RoHS compliance must use the SDR1806-102KL.

Q: How do the saturation current specifications compare?

A: The SMP5022-104M has saturation current (Isat) of 1.2A, while the SDR1806-102KL has Isat of 1A. The substitute part saturates at lower current levels. Circuits operating near saturation limits must account for this 0.2A difference in performance characteristics.
