Substitute Part Grouping Explanation
Substitution eligibility for the PM54-100M is determined by the following critical parameters:
- Inductance value: 10 µH (exact match required)
- Inductance tolerance: ±20% or tighter
- Current rating: minimum 1.44 A
- DC resistance: 100mOhm or lower
- Core material: Ferrite
- Shielding: Unshielded
- Mounting type: Surface Mount
- Physical footprint: compatible with 5.80mm x 5.80mm x 4.80mm envelope
- Operating temperature range: must encompass or exceed -30°C to 100°C
Substitute parts are classified into two categories:
Direct Substitutes (Bourns Inc. PM54 and SDR0604 Series): Parts that maintain identical electrical specifications and physical dimensions, with improved product status (active) and enhanced compliance certifications.
Similar Substitutes (Sumida and API Delevan): Parts that meet core electrical requirements with minor dimensional variations and equivalent performance characteristics.

Engineering Selection Recommendations
Primary Recommendation: PM54-100M-RC
The PM54-100M-RC is the direct successor to the PM54-100M within the Bourns PM54 series. It maintains identical electrical specifications (10 µH, ±20% tolerance, 1.44 A rating, 100mOhm DCR) and physical dimensions. The part transitions from obsolete to active product status and achieves ROHS3 compliance. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin. This part is available in Tape & Reel packaging with 48,247 units in stock.
Secondary Recommendation: SDR0604-100ML
The SDR0604-100ML from the Bourns SDR0604 series provides equivalent electrical performance with identical inductance, tolerance, current rating, and DCR specifications. It is ROHS3 compliant and active. Available in Cut Tape and Digi-Reel packaging with 6,299 units in stock. The extended temperature range (-40°C to 125°C) exceeds the original part requirements.
Alternative Recommendation: CR54NP-100MC
The CR54NP-100MC from Sumida America Components Inc. meets all core electrical requirements with 10 µH inductance, ±20% tolerance, 1.44 A current rating, and 100mOhm maximum DCR. It is ROHS3 compliant and active. Physical dimensions are within acceptable tolerance (5.80mm x 5.30mm x 4.85mm). This option provides supply diversity with 5,208 units in stock.
Extended Temperature Range Option: PD54R-103K
The PD54R-103K from API Delevan Inc. offers the widest operating temperature range (-55°C to 125°C) and tighter inductance tolerance (±10%). It maintains 1.44 A current rating and 100mOhm maximum DCR. This part is suitable for applications requiring extended thermal performance. Physical dimensions are slightly smaller (5.70mm x 5.11mm x 4.50mm). 1,064 units are in stock.
Frequently Asked Questions (FAQ)
Q: Can PM54-100M-RC be used as a direct replacement for PM54-100M?
A: Yes. The PM54-100M-RC maintains identical inductance (10 µH), tolerance (±20%), current rating (1.45 A, exceeding the 1.44 A requirement), and DC resistance (100mOhm). Physical dimensions and mounting type are identical. The part is pin-compatible and functionally equivalent.
Q: What is the difference between PM54-100M-RC and SDR0604-100ML?
A: Both parts are manufactured by Bourns Inc. and meet identical electrical specifications. PM54-100M-RC is packaged in Tape & Reel format with higher inventory (48,247 units). SDR0604-100ML is available in Cut Tape and Digi-Reel packaging with lower inventory (6,299 units). Selection depends on packaging requirements and procurement lead times.
Q: Are the Sumida parts (CR54NP-100MC, CD54NP-100MC) compatible with the original PM54-100M?
A: Yes, both Sumida parts meet the electrical requirements: 10 µH inductance, ±20% tolerance, 1.44 A current rating, and 100mOhm maximum DCR. Physical dimensions are within acceptable tolerance. Both are ROHS3 compliant and active. These parts provide supply chain alternatives from a different manufacturer.
Q: Why does PD54R-103K have a ±10% tolerance instead of ±20%?
A: The PD54R-103K from API Delevan Inc. offers tighter inductance tolerance (±10%) compared to the original PM54-100M (±20%). This provides improved inductance accuracy and is suitable for applications with stricter tolerance requirements. The part remains fully compatible with designs accepting ±20% tolerance.
Q: What is the impact of the extended temperature range in substitute parts?
A: Most substitute parts extend the operating temperature range from -30°C to 100°C (original) to -40°C to 125°C. This provides additional thermal margin and is beneficial for applications in extreme environments. The PD54R-103K extends further to -55°C to 125°C. Extended temperature ranges do not negatively impact designs operating within the original specification.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts listed are ROHS3 compliant. The original PM54-100M is RoHS non-compliant. If RoHS compliance is required for your application, any of the substitute parts satisfy this requirement.
Q: What packaging options are available for these substitutes?
A: PM54-100M-RC is available in Tape & Reel (TR) format. SDR0604-100ML is available in Cut Tape (CT) and Digi-Reel format. CR54NP-100MC and PD54R-103K are available in Tape & Reel format. CD54NP-100MC is available in Tape & Reel format. Packaging selection depends on assembly equipment and procurement volume requirements.
