5627-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5627-RC is a 250 µH unshielded drum core wirewound inductor rated for 9 A continuous current with a maximum DC resistance of 40 mOhm. This through-hole radial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5627-RC is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for legacy systems and new designs requiring identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the 5627-RC is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish direct substitutability:

  • Inductance value: 250 µH at 1 kHz test frequency
  • Inductance tolerance: ±10%
  • Current rating: 9 A minimum
  • DC resistance: 40 mOhm maximum
  • Core material and shielding: Ferrite, unshielded
  • Mounting configuration: Through-hole radial
  • Package geometry: Vertical cylinder with 1.500" diameter
  • Regulatory compliance: ROHS3 compliant

The Hammond Manufacturing 1539M27 meets all specified electrical and mechanical parameters and qualifies as a direct equivalent.

Engineering Selection Recommendations

The Hammond Manufacturing 1539M27 is electrically and functionally equivalent to the Bourns 5627-RC across all critical parameters: inductance, current rating, DC resistance, core material, and mounting configuration. Both components are ROHS3 compliant and meet identical regulatory requirements.

The 1539M27 is currently in active production status with confirmed inventory availability, whereas the 5627-RC is obsolete. Selection of the 1539M27 ensures long-term supply chain continuity and component availability for production and repair applications.

The height difference (1.500" vs. 1.110") must be evaluated for mechanical fit within the target application. If vertical clearance is constrained, this dimension requires verification against PCB layout and enclosure specifications.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1539M27 directly replace the Bourns 5627-RC in existing designs?

A: Yes, the 1539M27 is electrically equivalent across all specified parameters: 250 µH inductance, 9 A current rating, and 40 mOhm maximum DC resistance. Both components use identical ferrite drum core construction and through-hole radial mounting. Mechanical fit must be confirmed, as the 1539M27 seated height is 1.500" compared to 1.110" for the 5627-RC.

Q: What is the significance of the product status difference?

A: The 5627-RC is classified as obsolete, indicating discontinued manufacturing. The 1539M27 is in active production with current inventory availability. For new designs and ongoing production, the 1539M27 provides assured supply and long-term component availability.

Q: Are both components RoHS compliant?

A: Yes, both the 5627-RC and 1539M27 are ROHS3 compliant and meet identical environmental and regulatory standards.

Q: What parameters determine substitutability for this inductor category?

A: Direct substitution is established by matching inductance value (250 µH), inductance tolerance (±10%), current rating (9 A), DC resistance (40 mOhm maximum), core material (ferrite, unshielded), and mounting type (through-hole radial). Package geometry and operating temperature range must also align with application requirements.

Q: Does the height difference affect electrical performance?

A: No, the height difference does not affect electrical characteristics. However, it impacts mechanical fit within the PCB layout and enclosure. Applications with vertical space constraints must verify clearance before component selection.
