Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD54R-224K is determined by the following critical parameters:

• Inductance value: 220 µH ±10%
• Current rating: minimum 350 mA continuous
• DC resistance: maximum 1.57Ohm
• Core material and type: Ferrite drum core wirewound
• Shielding configuration: Unshielded
• Mounting: Surface mount
• Package compatibility: Nonstandard form factor
• Compliance: ROHS3 and REACH requirements

The SDR0604-221KL from Bourns Inc. meets all substitution criteria with matching inductance, current rating, and DC resistance specifications. Both parts share identical core construction, shielding characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PD54R-224K and SDR0604-221KL are active production components with ROHS3 compliance and REACH unaffected status. The SDR0604-221KL provides a higher saturation current rating of 440 mA compared to the 350 mA specification of the PD54R-224K, offering improved current margin. The operating temperature range of the PD54R-224K extends to -55°C, providing broader low-temperature coverage than the SDR0604-221KL minimum of -40°C. Physical dimensions are similar with minor variations in footprint and height. Selection between these parts should account for specific application temperature requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-221KL directly replace the PD54R-224K in all applications?

A: The SDR0604-221KL meets all critical electrical specifications including inductance, current rating, and DC resistance. Physical dimensions are similar. Applications requiring operation below -40°C must retain the PD54R-224K due to its extended temperature range to -55°C.

Q: What are the key electrical parameters that define substitution eligibility?

A: Inductance value of 220 µH, current rating of 350 mA minimum, DC resistance maximum of 1.57Ohm, ferrite drum core construction, and unshielded configuration are the primary criteria. Both parts meet these specifications.

Q: Are there packaging or footprint considerations?

A: Both parts use surface mount packaging in nonstandard form factors. The SDR0604-221KL has a slightly larger footprint (0.228" x 0.228" versus 0.224" x 0.201") and greater seated height (0.189" versus 0.177"). PCB layout compatibility should be verified for space-constrained applications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the PD54R-224K and SDR0604-221KL are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

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

A: The SDR0604-221KL has a saturation current of 440 mA compared to 350 mA for the PD54R-224K. This provides additional headroom in the Bourns part for transient current conditions while maintaining the same continuous current rating of 350 mA.
