Substitute Part Grouping Explanation

The SDR0805-820KL qualifies as a direct substitute for the PM75-820K-RC based on electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

• Inductance value matches: 82 µH with ±10% tolerance
• Current rating is equal or greater: 780 mA minimum
• Saturation current (Isat) is equal or greater: 1.2 A minimum
• DC resistance does not exceed specification: 370 mOhm maximum
• Core material and shielding configuration are identical: Ferrite, unshielded
• Q factor and self-resonant frequency characteristics are equivalent
• Operating temperature range encompasses or matches: -40°C to 125°C
• Physical dimensions and height are identical for PCB layout compatibility
• Compliance certifications are equivalent: ROHS3, MSL 1

Parameter Comparison

Engineering Selection Recommendations

Both the PM75-820K-RC and SDR0805-820KL are active production parts from Bourns Inc. with identical electrical specifications and mechanical dimensions. Selection between these parts may be based on inventory availability, supply chain considerations, or procurement preferences, as all functional and compliance parameters are equivalent.

The SDR0805-820KL currently maintains higher inventory availability (1936 pcs) compared to the PM75-820K-RC (1066 pcs), which may influence procurement decisions for high-volume applications. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing processes and long-term storage without moisture sensitivity constraints.
