Parameter Comparison

Engineering Selection Recommendations

SD52-220-R (Eaton - Electronics Division)

Primary specification with highest current rating (860 mA) and saturation current (730 mA). Suitable for applications requiring maximum current handling within the 22 µH inductance class. RoHS Compliant status and Active product status support long-term availability. Operating temperature range extends to 125°C.

SRU5018-220Y (Bourns Inc.)

Substitute option with lower DC resistance (160 mOhm) compared to the primary part. Current rating of 680 mA and saturation current of 650 mA are suitable for applications with reduced current demands. ROHS3 Compliant and REACH Unaffected status. Identical package footprint (5.20mm x 5.20mm x 2.00mm) enables direct PCB layout compatibility. Higher inductance tolerance (±30%) requires circuit validation in precision-dependent applications.

VLCF5020T-220MR75-1 (TDK Corporation)

Substitute option with saturation current matching the primary part (750 mA). Slightly smaller footprint (5.00mm x 5.00mm) requires PCB layout verification. DC resistance of 496 mOhm maximum is higher than primary and Bourns alternatives. Operating temperature range limited to 105°C maximum. ROHS3 Compliant and REACH Unaffected status. Packaging available in Cut Tape (CT) & Digi-Reel® format.

Frequently Asked Questions (FAQ)

Q: Can SRU5018-220Y replace SD52-220-R in all applications?

A: SRU5018-220Y is suitable for applications where the current requirement does not exceed 680 mA continuous. The lower saturation current (650 mA vs. 730 mA) and higher inductance tolerance (±30% vs. ±20%) must be evaluated against circuit specifications. Identical package dimensions (5.20mm x 5.20mm x 2.00mm) support direct PCB substitution.

Q: What is the impact of DC resistance differences between these parts?

A: DC resistance affects power dissipation and thermal performance. SD52-220-R (204.2 mOhm) and SRU5018-220Y (160 mOhm) have comparable resistance values. VLCF5020T-220MR75-1 (496 mOhm maximum) exhibits significantly higher resistance, resulting in increased power loss. Applications sensitive to thermal performance or efficiency require DCR evaluation.

Q: Are package dimensions interchangeable between all three parts?

A: SD52-220-R and SRU5018-220Y share identical footprints (5.20mm x 5.20mm x 2.00mm). VLCF5020T-220MR75-1 has a slightly smaller footprint (5.00mm x 5.00mm x 2.00mm). PCB layout compatibility must be verified for the TDK part, particularly in space-constrained designs.

Q: What is the significance of inductance tolerance in substitution?

A: SD52-220-R and VLCF5020T-220MR75-1 both specify ±20% tolerance. SRU5018-220Y specifies ±30% tolerance. Applications requiring tighter inductance control (filter circuits, impedance matching) should prioritize parts with ±20% tolerance. General-purpose applications tolerate ±30% variation.

Q: How do operating temperature ranges affect part selection?

A: SD52-220-R and SRU5018-220Y both operate from -40°C to 125°C. VLCF5020T-220MR75-1 operates from -40°C to 105°C. Applications requiring operation above 105°C must use SD52-220-R or SRU5018-220Y.

Q: What packaging formats are available for these parts?

A: SD52-220-R and SRU5018-220Y are supplied in Tape & Reel (TR) format. VLCF5020T-220MR75-1 is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly process requirements and volume specifications.

Q: Are all three parts RoHS compliant?

A: SD52-220-R is RoHS Compliant. SRU5018-220Y and VLCF5020T-220MR75-1 are ROHS3 Compliant. All parts meet RoHS requirements for lead-free and restricted substance compliance. SRU5018-220Y and VLCF5020T-220MR75-1 also carry REACH Unaffected status.
