Key Parameters

Substitute Part Grouping Explanation

Substitution of the 23220C is determined by the following critical parameters:

• Inductance Value: 22 µH (exact match required)
• Current Rating: Minimum 740 mA continuous current capability
• DC Resistance: Maximum 361mOhm to maintain circuit performance
• Mounting Type: Surface Mount configuration
• Physical Dimensions: 4.50mm x 4.00mm footprint compatibility
• Shielding Classification: Unshielded topology
• Regulatory Compliance: RoHS3 and REACH status

The Bourns Inc. SDR0403-220ML meets these substitution criteria with equivalent inductance, compatible current rating, and matching physical footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the 23220C and SDR0403-220ML are Active status components with full RoHS3 compliance and REACH unaffected status. The SDR0403-220ML provides equivalent inductance and current rating performance with a wider operating temperature range (-40°C to 125°C versus -40°C to 85°C). The DC resistance specification of the SDR0403-220ML (380mOhm Max) is within acceptable tolerance relative to the 23220C (361mOhm Max). Physical footprint compatibility is confirmed with identical length and width dimensions (4.50mm x 4.00mm), though the seated height differs by 0.012" (0.30mm). Component selection should be based on circuit thermal requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the SDR0403-220ML directly replace the 23220C in existing designs?

A: The SDR0403-220ML is electrically compatible as a substitute based on matching inductance value (22 µH), equivalent current rating (760 mA versus 740 mA), and identical footprint dimensions (4.50mm x 4.00mm). The DC resistance specification (380mOhm Max) is within acceptable operating parameters. Physical clearance verification is required due to the 0.30mm height difference (4.60mm versus 3.20mm seated height).

Q: What are the critical parameters for substitution?

A: Substitution eligibility is determined by inductance value (22 µH exact match), minimum current rating of 740 mA, DC resistance not exceeding 361mOhm, unshielded topology, surface mount configuration, and 4.50mm x 4.00mm footprint compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes, both the 23220C and SDR0403-220ML are ROHS3 Compliant with REACH Unaffected status.

Q: What is the difference in operating temperature range?

A: The 23220C operates from -40°C to 85°C, while the SDR0403-220ML operates from -40°C to 125°C. The SDR0403-220ML provides extended high-temperature capability for applications requiring operation above 85°C.

Q: How do the DC resistance values compare?

A: The 23220C specifies 361mOhm Max DC resistance, while the SDR0403-220ML specifies 380mOhm Max. This 19mOhm difference represents approximately 5.3% variance and falls within acceptable tolerance for most circuit applications.
