Key Parameters

Substitute Part Grouping Explanation

The SDR0604-390KL from Bourns Inc. qualifies as a direct substitute based on the following electrical and mechanical alignment:

Electrical Parameters: Both parts specify 39 µH inductance with ±10% tolerance, 800 mA current rating, and 320 mOhm maximum DC resistance. The SDR0604-390KL provides a saturation current of 1A, which exceeds the 800 mA requirement of the PD54R-393K.

Mechanical Parameters: Both components use ferrite drum core construction, unshielded configuration, and surface mount packaging. Physical dimensions are comparable (PD54R-393K: 5.70mm × 5.11mm × 4.50mm; SDR0604-390KL: 5.80mm × 5.80mm × 4.80mm), permitting board layout compatibility within standard PCB design tolerances.

Compliance: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.

Parameter Comparison

Engineering Selection Recommendations

Both the PD54R-393K and SDR0604-390KL are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on availability, lead time, and application-specific temperature requirements. The PD54R-393K supports operation down to -55°C, while the SDR0604-390KL operates from -40°C minimum. Applications requiring the extended low-temperature range must use the PD54R-393K. For standard commercial and industrial applications within the -40°C to 125°C window, either part is functionally equivalent. Current inventory levels show 4200 units of SDR0604-390KL available versus 1032 units of PD54R-393K.

Frequently Asked Questions (FAQ)

Q: Can SDR0604-390KL replace PD54R-393K in all applications?

A: Electrical and mechanical specifications are equivalent. The SDR0604-390KL operates at a minimum temperature of -40°C versus -55°C for the PD54R-393K. Applications requiring operation below -40°C must use the original PD54R-393K.

Q: Are there physical footprint differences between these inductors?

A: Dimensions differ slightly. PD54R-393K measures 5.70mm × 5.11mm × 4.50mm; SDR0604-390KL measures 5.80mm × 5.80mm × 4.80mm. Both are surface mount nonstandard packages. PCB layout should accommodate the larger footprint of the SDR0604-390KL if substitution is planned.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified as EAR99 with identical HTSUS codes (8504.50.4000).

Q: What is the saturation current difference, and does it matter?

A: PD54R-393K saturates at 800 mA; SDR0604-390KL saturates at 1 A. For circuits operating at or near 800 mA, the SDR0604-390KL provides additional margin before saturation occurs.

Q: Which part should be selected for new designs?

A: Selection depends on temperature range requirements and supply chain factors. For designs requiring -55°C operation, specify PD54R-393K. For standard industrial applications, either part is acceptable based on availability and lead time.
