PM74SB-150M-RC Equivalent & Substitute Parts

Part Overview

The PM74SB-150M-RC is a 15 µH shielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.39 A continuous current with a maximum DC resistance of 80 mOhm. This surface mount component operates across the industrial temperature range of -40°C to 125°C and is ROHS3 compliant. The part is currently active in production with substantial inventory availability. Substitute parts are identified when equivalent inductance values, shielding characteristics, and operating temperature ranges align with application requirements while accommodating variations in current ratings and DC resistance within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM74SB-150M-RC is determined by the following critical parameters:

• Inductance value of 15 µH with ±20% tolerance
• Shielded construction to maintain electromagnetic isolation
• Surface mount packaging for PCB integration compatibility
• Operating temperature range of -40°C to 125°C minimum
• ROHS3 compliance for regulatory alignment

The substitute part PF0464.153NL meets these core criteria. While the substitute exhibits a higher current rating (2.35 A versus 1.39 A) and lower DC resistance (75 mOhm versus 80 mOhm), these variations represent improvements in performance headroom and are acceptable for applications where the PM74SB-150M-RC is specified. The substitute's self-resonant frequency of 24 MHz exceeds the original part's 20 MHz, indicating broader frequency response capability.

Parameter Comparison

Engineering Selection Recommendations

Both the PM74SB-150M-RC and PF0464.153NL are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The PF0464.153NL provides enhanced current handling capacity and reduced DC resistance, making it suitable for applications requiring additional thermal margin or lower power dissipation. Selection between these parts should be based on physical footprint constraints, as the PM74SB-150M-RC measures 7.80mm × 7.00mm × 4.90mm (height seated), while the PF0464.153NL measures 7.20mm × 7.20mm × 3.00mm (height seated). The substitute's lower profile may offer advantages in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can PF0464.153NL replace PM74SB-150M-RC in existing designs?

A: Yes, provided the physical dimensions and packaging format are compatible with the PCB layout. Both parts share identical inductance values, tolerance, operating temperature range, and shielding characteristics. The substitute's improved current rating and lower DC resistance represent performance enhancements.

Q: What are the key differences between these inductors?

A: The primary differences are current rating (2.35 A versus 1.39 A), DC resistance (75 mOhm versus 80 mOhm), self-resonant frequency (24 MHz versus 20 MHz), and physical dimensions. The substitute is more compact in height (3.00mm versus 4.90mm).

Q: Are both parts suitable for high-frequency applications?

A: Both inductors operate within acceptable frequency ranges for their respective self-resonant frequencies. The PM74SB-150M-RC is rated to 20 MHz, while the PF0464.153NL extends to 24 MHz, providing broader frequency response capability.

Q: Do packaging differences affect PCB assembly?

A: The PM74SB-150M-RC is supplied in Tape & Reel format, while the PF0464.153NL is supplied in Tray format. Assembly equipment compatibility should be verified with your manufacturing partner. Both are surface mount components suitable for automated placement.

Q: Are regulatory certifications equivalent?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control. Regulatory status is equivalent for both components.
