Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PD54R-562M is determined by the following critical parameters:

• Inductance Value: 5.6 µH (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Current Rating: 1.7 A minimum (equal or higher acceptable)
• DC Resistance: 85 mOhm maximum (lower values acceptable)
• Core Type: Ferrite, unshielded drum core wirewound
• Mounting: Surface mount, nonstandard package
• Compliance: ROHS3 compliant, REACH unaffected

The substitute part SDR0604-5R6ML meets all critical substitution criteria with equivalent inductance, tolerance, current rating, and compliance certifications. Minor variations in DC resistance (80 mOhm vs. 85 mOhm) and saturation current (2.7 A vs. 1.7 A) represent improvements in performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the PD54R-562M and SDR0604-5R6ML are Active products with ROHS3 compliance and REACH unaffected status, qualifying them for equivalent use in applications requiring 5.6 µH inductance at 1.7 A. The SDR0604-5R6ML offers lower DC resistance (80 mOhm vs. 85 mOhm) and higher saturation current (2.7 A vs. 1.7 A), representing equivalent or superior electrical performance. Selection between these parts should be based on availability, lead time, and procurement requirements rather than electrical limitations.

Frequently Asked Questions (FAQ)

Q: Can SDR0604-5R6ML replace PD54R-562M in all applications?

A: Yes. Both parts share identical inductance (5.6 µH), tolerance (±20%), current rating (1.7 A), core material (ferrite), shielding (unshielded), and mounting type (surface mount). The SDR0604-5R6ML exhibits lower DC resistance and higher saturation current, which are compatible with or beneficial to circuit performance.

Q: What is the difference in DC resistance between these parts?

A: The PD54R-562M has a maximum DC resistance of 85 mOhm, while the SDR0604-5R6ML has a maximum of 80 mOhm. The lower resistance of the substitute part reduces power dissipation and heat generation.

Q: Are there package dimension differences?

A: Both parts use nonstandard surface mount packages. The PD54R-562M measures 0.224" L x 0.201" W x 0.177" H (5.70mm x 5.11mm x 4.50mm). The SDR0604-5R6ML measures 0.228" L x 0.228" W x 0.189" H (5.80mm x 5.80mm x 4.80mm). Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PD54R-562M and SDR0604-5R6ML are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the operating temperature range difference?

A: The PD54R-562M operates from -55°C to 125°C, while the SDR0604-5R6ML operates from -40°C to 125°C. For applications requiring operation below -40°C, the PD54R-562M is required.
