Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM32-560M-RC is determined by the following critical parameters:

Inductance value must be 56 µH with tolerance specifications that maintain circuit performance within design margins. Current rating and saturation current must support 340 mA operation. DC resistance must not exceed 1.45Ohm maximum to ensure thermal and efficiency requirements are met. Core material must be ferrite with unshielded drum core construction. Physical dimensions must match 3.00mm x 2.80mm to ensure PCB footprint compatibility. Surface mount packaging and operating temperature range of -40°C to 125°C are mandatory for application compatibility. RoHS3 compliance and MSL rating of 1 (Unlimited) are required for manufacturing and supply chain standards.

The SDR0302-560KL meets all substitution criteria with identical electrical performance and physical specifications, with the distinction of tighter inductance tolerance (±10% versus ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both PM32-560M-RC and SDR0302-560KL are active production components from Bourns Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inductance tolerance requirements. The PM32-560M-RC provides ±20% tolerance, suitable for applications with broader tolerance margins. The SDR0302-560KL offers tighter ±10% tolerance, appropriate for circuits requiring more precise inductance values. Both parts maintain identical electrical performance across current rating, DC resistance, Q factor, and self-resonant frequency specifications. Inventory availability and lead time considerations may also influence part selection, as the SDR0302-560KL currently maintains higher stock levels (3600 pcs versus 648 pcs).

Frequently Asked Questions (FAQ)

Q: Can SDR0302-560KL be used as a direct replacement for PM32-560M-RC?

A: Yes. Both parts share identical inductance value (56 µH), current rating (340 mA), DC resistance (1.45Ohm max), core type (ferrite drum core unshielded), physical dimensions (3.00mm x 2.80mm), and operating temperature range (-40°C to 125°C). The SDR0302-560KL features tighter inductance tolerance (±10% versus ±20%), which provides improved performance consistency.

Q: What is the primary difference between these two part numbers?

A: The inductance tolerance specification differs. PM32-560M-RC carries ±20% tolerance while SDR0302-560KL carries ±10% tolerance. All other electrical and mechanical parameters are identical. The tighter tolerance of the SDR0302-560KL may be advantageous in precision circuit applications.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both parts have identical package dimensions of 3.00mm length x 2.80mm width with 2.80mm seated height, ensuring compatibility with the same surface mount footprint and reflow soldering process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PM32-560M-RC and SDR0302-560KL are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited), meeting identical regulatory and supply chain requirements.

Q: Which part should be selected for applications requiring precise inductance values?

A: The SDR0302-560KL with ±10% inductance tolerance is appropriate for applications where inductance precision is critical. The PM32-560M-RC with ±20% tolerance is suitable for applications with broader tolerance margins.
