Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD73R-562M is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 5.6 µH with ±20% tolerance
• Core type: Ferrite drum core, wirewound construction
• Shielding configuration: Unshielded
• Mounting technology: Surface mount

Secondary Compatibility Factors:

• Current rating must equal or exceed 1.9 A
• DC resistance must not exceed 65 mOhm
• Operating temperature range must encompass or match -55°C ~ 125°C
• RoHS and REACH compliance status

The SDR0805-5R6ML from Bourns Inc. qualifies as a substitute based on matching inductance, core material, shielding type, and mounting configuration. The substitute demonstrates superior electrical performance with higher current rating (4.6 A) and lower DC resistance (40 mOhm Max), providing enhanced capability for the same functional application.

Parameter Comparison

Engineering Selection Recommendations

The SDR0805-5R6ML is suitable for direct substitution in applications currently using the PD73R-562M. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part is actively manufactured and stocked, providing supply chain continuity for the obsolete PD73R-562M.

The SDR0805-5R6ML offers improved electrical performance with higher current rating and lower DC resistance, making it functionally superior for the same inductance specification. The operating temperature range of the substitute (-40°C ~ 125°C) covers the upper operational boundary of the original part; applications requiring the full -55°C lower limit must evaluate thermal performance requirements independently.

Physical dimensions differ slightly between the two components. The SDR0805-5R6ML measures 0.307" L x 0.307" W x 0.209" H (seated), compared to the PD73R-562M at 0.303" L x 0.272" W x 0.138" H (seated). PCB layout verification is required to confirm mechanical fit within existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SDR0805-5R6ML directly replace the PD73R-562M in existing designs?

A: The SDR0805-5R6ML matches the critical electrical parameters (inductance, tolerance, core type, shielding, and mounting technology) required for functional substitution. Physical dimensions differ, requiring PCB layout verification. The substitute provides superior current handling and lower resistance characteristics.

Q: What are the key differences between these two inductors?

A: Both components share identical inductance (5.6 µH), tolerance (±20%), core material (ferrite), shielding (unshielded), and mounting type (surface mount). The SDR0805-5R6ML provides higher current rating (4.6 A vs. 1.9 A), lower DC resistance (40 mOhm vs. 65 mOhm), and active product status versus obsolete. Operating temperature ranges differ at the lower limit (-40°C vs. -55°C).

Q: Are there packaging differences between these parts?

A: The PD73R-562M uses nonstandard packaging, while the SDR0805-5R6ML is supplied in Tape & Reel (TR) format. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Do both parts meet the same compliance standards?

A: Both the PD73R-562M and SDR0805-5R6ML are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for electronic component applications.

Q: What should be evaluated before implementing the SDR0805-5R6ML as a substitute?

A: Verify PCB layout compatibility due to dimensional differences. Confirm that the operating temperature range of -40°C to 125°C satisfies application requirements. Validate that the improved electrical performance (higher current rating, lower resistance) does not introduce unintended circuit behavior changes.
