Key Parameters

Substitute Part Grouping Explanation

Substitution of the 24221C is determined by strict equivalence across the following electrical parameters: inductance value of 220 µH, current rating of 350 mA, and maximum DC resistance of 1.57Ohm. The substitute part SDR0604-221KL from Bourns Inc. meets these core electrical specifications. Both parts are unshielded surface mount inductors with identical inductance and current ratings. Mechanical compatibility is confirmed through nonstandard package classification and surface mount mounting type. Compliance requirements are satisfied through ROHS3 certification and MSL Level 1 rating for both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the 24221C and SDR0604-221KL are active products with full RoHS3 compliance and REACH unaffected status. The SDR0604-221KL provides an extended operating temperature range of -40°C to 125°C compared to the 24221C range of -40°C to 85°C. Selection between these parts depends on the specific thermal requirements of the application. For applications operating within the -40°C to 85°C range, either part is suitable. For applications requiring operation above 85°C, the SDR0604-221KL is the appropriate selection. Both parts carry MSL Level 1 rating, indicating unlimited moisture sensitivity protection.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for the SDR0604-221KL to substitute the 24221C?

A: The inductance value (220 µH), current rating (350 mA), and maximum DC resistance (1.57Ohm) must remain identical. Both parts meet these specifications.

Q: Are there mechanical compatibility concerns between these parts?

A: Both parts are surface mount inductors with nonstandard package classification. The 24221C measures 0.228" L x 0.205" W x 0.177" H (5.80mm x 5.20mm x 4.50mm), while the SDR0604-221KL measures 0.228" L x 0.228" W x 0.189" H (5.80mm x 5.80mm x 4.80mm). Verify PCB layout and clearance requirements for your specific application.

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

A: The SDR0604-221KL features a drum core ferrite construction with an extended operating temperature range to 125°C, compared to the 24221C which operates to 85°C. The SDR0604-221KL also specifies saturation current (440mA) and quality factor (20 @ 796kHz).

Q: Are both parts available in the same packaging format?

A: Yes, both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: Do compliance certifications differ between these parts?

A: No, both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 moisture sensitivity rating.
