Substitute Part Grouping Explanation

The SDR1806-681KL from Bourns Inc. qualifies as a substitute for the SMP5022-683M based on the following alignment of critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Inductance value: Both parts rated at 680 µH, matching the primary functional requirement
• Current rating: SDR1806-681KL rated at 700 mA versus SMP5022-683M at 720 mA, representing acceptable operational margin within the same application class
• DC resistance: SDR1806-681KL at 1.2 Ohm Max versus SMP5022-683M at 1.1 Ohm Max, a minor variance acceptable for equivalent circuit performance
• Saturation current: SDR1806-681KL at 1.2 A versus SMP5022-683M at 1.4 A, both providing adequate headroom for typical applications
• Core material: Both utilize ferrite cores, ensuring consistent magnetic properties
• Shielding: Both are unshielded configurations

Mechanical Compatibility Criteria:

• Mounting type: Both are surface mount components
• Package classification: Both are nonstandard packages
• Physical dimensions: Comparable footprints (19.04mm x 15.74mm versus 18.30mm x 14.00mm) and heights (7.11mm versus 6.90mm) suitable for equivalent PCB layouts
• Moisture sensitivity: Both rated MSL 1 (Unlimited)

Regulatory Alignment:

• Both components are REACH Unaffected and classified as EAR99

Parameter Comparison

Engineering Selection Recommendations

SMP5022-683M Selection Criteria:

• Primary choice when Gowanda Electronics supply availability is confirmed
• Preferred for applications requiring the extended lower temperature operating range (-55°C minimum versus -40°C)
• Suitable when the ±20% inductance tolerance meets circuit design specifications

SDR1806-681KL Selection Criteria:

• Applicable when Bourns Inc. supply chain provides better availability or lead time
• Preferred for applications where ROHS3 compliance is a design requirement
• Suitable for circuits where the tighter ±10% inductance tolerance provides design margin
• Acceptable when operating temperature minimum of -40°C satisfies application requirements
• Appropriate when the slightly reduced current rating (700 mA versus 720 mA) remains within circuit design parameters

Both components maintain Active product status and equivalent regulatory classification (EAR99, REACH Unaffected), supporting interchangeability within the specified electrical and mechanical parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can SDR1806-681KL directly replace SMP5022-683M in existing designs?

A: Direct substitution is supported when circuit design parameters accommodate the following differences: current rating of 700 mA (versus 720 mA), DC resistance of 1.2 Ohm Max (versus 1.1 Ohm Max), saturation current of 1.2 A (versus 1.4 A), and operating temperature minimum of -40°C (versus -55°C). Physical dimensions are comparable, supporting equivalent PCB layouts.

Q: What are the key electrical differences between these inductors?

A: The primary electrical differences are inductance tolerance (±10% for SDR1806-681KL versus ±20% for SMP5022-683M), DC resistance (1.2 Ohm Max versus 1.1 Ohm Max), and saturation current (1.2 A versus 1.4 A). Both maintain identical 680 µH inductance values and ferrite core construction.

Q: Are there mechanical compatibility concerns?

A: Physical dimensions differ slightly (18.30mm x 14.00mm versus 19.04mm x 15.74mm for length and width; 6.90mm versus 7.11mm for height). Both are nonstandard packages with comparable footprints suitable for equivalent surface mount PCB layouts. Verify specific board layout constraints before substitution.

Q: What compliance differences exist between these parts?

A: SDR1806-681KL carries ROHS3 compliance certification, while SMP5022-683M is marked as not applicable. Both are REACH Unaffected and classified as EAR99. Select based on specific design compliance requirements.

Q: Which part should be selected for temperature-critical applications?

A: SMP5022-683M supports the extended operating range of -55°C to 125°C, while SDR1806-681KL operates from -40°C to 125°C. Applications requiring operation below -40°C require SMP5022-683M.
