Key Parameters

Substitute Part Grouping Explanation

The SDR0604-1R5ML from Bourns Inc. qualifies as a direct substitute for the PD54R-152M based on the following matching electrical and mechanical parameters:

Matching Parameters:

• Inductance: Both parts are rated at 1.5 µH with ±20% tolerance
• Core Type: Both are ferrite drum core wirewound inductors
• Shielding: Both are unshielded configurations
• Mounting: Both use surface mount technology
• Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited) rating
• Operating Temperature: Both support -40°C to 125°C minimum range (SDR0604 extends the lower bound from -55°C to -40°C)

Performance Differences:

• Current Rating: SDR0604-1R5ML provides 3.6 A versus 2.7 A (33% higher capacity)
• DC Resistance: SDR0604-1R5ML offers 30 mOhm Max versus 55 mOhm Max (45% lower resistance)
• Size: SDR0604-1R5ML measures 5.80mm x 5.80mm versus 5.70mm x 5.11mm (slightly larger footprint)

Parameter Comparison

Engineering Selection Recommendations

Both the PD54R-152M and SDR0604-1R5ML are Active products with identical ROHS3 compliance and MSL 1 (Unlimited) ratings, making them suitable for equivalent circuit substitution where the same inductance value is required.

The SDR0604-1R5ML provides superior electrical performance characteristics with 33% higher continuous current capacity and 45% lower DC resistance, presenting an upgrade path for designs requiring enhanced thermal efficiency or additional design margin on current handling.

The PD54R-152M maintains a lower operating temperature floor of -55°C compared to -40°C for the SDR0604-1R5ML, making it the necessary choice for applications requiring extended low-temperature performance.

Both parts maintain identical voltage and frequency performance envelopes at their rated inductance, supporting cross-substitution in standard boost converter, buck-boost, and filter applications where the inductance value is the primary circuit requirement.

Frequently Asked Questions (FAQ)

Q: Can SDR0604-1R5ML directly replace PD54R-152M in all applications?

A: Yes, for applications operating above -40°C. The SDR0604-1R5ML provides superior electrical performance with higher current rating and lower DC resistance. For applications requiring operation below -40°C, the PD54R-152M is required to meet the extended temperature specification.

Q: What are the footprint considerations for substitution?

A: The SDR0604-1R5ML measures 5.80mm x 5.80mm with 4.80mm maximum seated height, while the PD54R-152M measures 5.70mm x 5.11mm with 4.50mm maximum seated height. Both parts are nonstandard package configurations suitable for surface mount assembly, but PCB layout must accommodate the slightly larger SDR0604-1R5ML footprint.

Q: Does the lower DC resistance of SDR0604-1R5ML provide circuit advantages?

A: The SDR0604-1R5ML's 30 mOhm Max DC resistance versus 55 mOhm Max for the PD54R-152M reduces I²R losses by approximately 45%, directly lowering thermal dissipation and improving converter efficiency. This advantage applies to all current levels, making it advantageous for power-critical designs.

Q: Are both parts suitable for production use?

A: Both the PD54R-152M and SDR0604-1R5ML are Active products with ROHS3 compliance and unlimited moisture sensitivity level ratings, making them suitable for volume production without supply risk constraints.
