Key Parameters

Substitute Part Grouping Explanation

The SDR1806-150ML from Bourns Inc. qualifies as a direct substitute based on the following critical parameters:

• Inductance Match: Both parts specify 15 µH at 100 kHz test frequency with ±20% tolerance
• Current Rating Compatibility: SDR1806-150ML rated at 4.3 A exceeds the 4 A requirement of SMP5022-152M
• DC Resistance Specification: SDR1806-150ML maximum 35 mOhm is within acceptable range relative to SMP5022-152M at 36 mOhm maximum
• Core Material: Both utilize ferrite core construction
• Shielding Configuration: Both are unshielded designs
• Operating Temperature: SDR1806-150ML range of -40°C to 125°C covers the primary operating window, with upper limit matching SMP5022-152M
• Mounting and Package: Both are surface mount components with nonstandard package configurations
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

Selection between SMP5022-152M and SDR1806-150ML should be based on the following criteria:

SMP5022-152M (Primary Selection) is appropriate when:

• Extended low-temperature operation below -40°C is required
• Gowanda Electronics supply chain is preferred or established
• Molded inductor construction is specified in design requirements
• Current inventory availability is critical

SDR1806-150ML (Substitute Selection) is appropriate when:

• ROHS3 compliance certification is mandatory for the end application
• Bourns Inc. supply chain is preferred or established
• Drum core wirewound construction is acceptable
• Slightly lower DC resistance (35 mOhm vs 36 mOhm) provides thermal performance benefit
• Higher current rating (4.3 A vs 4 A) provides additional design margin

Both parts maintain Active product status and are available in Tape & Reel packaging for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SDR1806-150ML be used as a direct replacement for SMP5022-152M in existing designs?

A: Yes, SDR1806-150ML meets all critical electrical parameters. Physical dimensions differ slightly (SDR1806-150ML: 0.720" L x 0.551" W x 0.272" H vs SMP5022-152M: 0.750" L x 0.620" W x 0.280" H), requiring PCB layout verification for footprint compatibility.

Q: What is the primary difference between these two inductors?

A: SMP5022-152M uses molded construction while SDR1806-150ML uses drum core wirewound construction. Both achieve identical inductance and tolerance specifications. SDR1806-150ML provides ROHS3 compliance certification.

Q: Are there temperature range limitations when substituting?

A: SMP5022-152M operates from -55°C to 125°C while SDR1806-150ML operates from -40°C to 125°C. If application requires operation below -40°C, SMP5022-152M is required.

Q: How do the DC resistance values compare?

A: SDR1806-150ML at 35 mOhm maximum is slightly lower than SMP5022-152M at 36 mOhm maximum. This difference is negligible for most applications and provides marginal thermal benefit with the substitute part.

Q: What packaging formats are available for both parts?

A: Both SMP5022-152M and SDR1806-150ML are supplied in Tape & Reel (TR) packaging suitable for automated surface mount assembly processes.
