Key Parameters

Substitute Part Grouping Explanation

Substitution of the LD2-560-R is based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 56 µH (exact match required)
• Core type: Ferrite drum core, wirewound, unshielded
• DC resistance: 240 mOhm maximum
• Saturation current: 1.5 A minimum
• Operating temperature range: -40°C to 125°C minimum
• Mounting: Surface mount configuration
• Compliance: RoHS status

The SDR0805-560KL from Bourns Inc. meets these core electrical specifications. However, the substitute part exhibits a lower continuous current rating of 940 mA compared to the main part's 1.96 A rating. This difference requires evaluation based on actual circuit requirements.

Engineering Selection Recommendations

LD2-560-R Selection Criteria: The LD2-560-R is the primary choice when continuous current requirements reach or exceed 1.5 A. This part carries Active product status with RoHS Compliant certification. The ±20% inductance tolerance is suitable for applications where tighter tolerance is not critical.

SDR0805-560KL Selection Criteria: The SDR0805-560KL from Bourns is suitable for applications where continuous current does not exceed 940 mA. This substitute offers improved inductance tolerance (±10% versus ±20%) and carries ROHS3 Compliant certification, indicating compliance with the latest RoHS directives. The part maintains identical DC resistance and saturation current specifications.

Compliance Considerations: Both parts are RoHS compliant and operate within the same temperature range. The SDR0805-560KL provides enhanced compliance status through ROHS3 certification and includes REACH Unaffected designation.

Frequently Asked Questions (FAQ)

Q: Can the SDR0805-560KL replace the LD2-560-R in all applications?

A: The SDR0805-560KL is electrically equivalent for inductance, DC resistance, and saturation current. However, the continuous current rating of 940 mA is lower than the LD2-560-R's 1.96 A rating. Substitution is valid only when circuit current requirements do not exceed 940 mA continuous operation.

Q: What are the physical differences between these parts?

A: The LD2-560-R measures 0.307" L x 0.276" W x 0.197" H (7.80mm x 7.00mm x 5.00mm). The SDR0805-560KL measures 0.307" L x 0.307" W x 0.209" H (7.80mm x 7.80mm x 5.30mm). The width and height differ slightly, requiring PCB layout verification before substitution.

Q: How do the inductance tolerances compare?

A: The LD2-560-R carries ±20% tolerance, while the SDR0805-560KL offers tighter ±10% tolerance. Applications requiring inductance accuracy benefit from the SDR0805-560KL specification.

Q: Are both parts suitable for high-temperature applications?

A: Both parts operate across -40°C to 125°C, meeting identical temperature requirements. No thermal performance differentiation exists between the two parts.

Q: What is the significance of the different RoHS certifications?

A: The LD2-560-R carries RoHS Compliant status, while the SDR0805-560KL carries ROHS3 Compliant status. ROHS3 represents the current RoHS directive version. Both certifications indicate lead-free and hazardous substance compliance; ROHS3 reflects the most recent regulatory framework.

Q: Can these parts be used interchangeably on the same PCB?

A: Physical dimensions differ slightly. PCB footprint and component placement must accommodate the SDR0805-560KL's larger width (7.80mm versus 7.00mm) and height (5.30mm versus 5.00mm) before substitution.
