Bourns 5523-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5523-RC is a 27 µH unshielded drum core wirewound inductor rated for 15 A continuous current with a maximum DC resistance of 10 mOhm. This through-hole radial component operates across the temperature range of -55°C to 105°C and is specified at 1 kHz inductance frequency. The 5523-RC is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 5523-RC is determined by the following critical parameters:

• Inductance value: 27 µH (exact match required)
• Current rating: 15 A minimum
• DC resistance: 10 mOhm maximum
• Physical form factor: Radial, horizontal cylinder configuration
• Mounting: Through-hole technology
• Shielding: Unshielded construction
• Regulatory compliance: ROHS3 compliant

The Hammond Manufacturing 1538M23 meets all substitution criteria within these electrical and mechanical boundaries. Both parts share identical inductance, current rating, DCR specification, physical dimensions, and mounting configuration, enabling direct functional replacement in circuit applications.

Engineering Selection Recommendations

The Hammond Manufacturing 1538M23 is the qualified substitute for the obsolete Bourns 5523-RC. Selection is based on:

• Product status: The 1538M23 maintains active manufacturing status, ensuring long-term availability and supply chain stability.
• Regulatory compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental standards.
• Electrical equivalence: Inductance, current rating, and DC resistance specifications are identical or superior (1538M23 offers tighter ±10% tolerance versus ±20%).
• Mechanical compatibility: Identical physical dimensions and radial through-hole configuration enable direct PCB mounting without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M23 directly replace the Bourns 5523-RC in existing designs?

A: Yes. Both inductors share identical electrical specifications (27 µH, 15 A, 10 mOhm DCR), physical dimensions (1.000" Dia x 1.380" L), and mounting configuration (radial through-hole). Direct substitution is supported without circuit redesign.

Q: What is the difference in tolerance between these parts?

A: The Bourns 5523-RC specifies ±20% inductance tolerance, while the Hammond 1538M23 specifies ±10%. The tighter tolerance of the substitute part provides improved circuit performance consistency.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the Bourns 5523-RC and Hammond 1538M23 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the primary reason for substitution?

A: The Bourns 5523-RC is classified as obsolete. The Hammond 1538M23 is an active product with confirmed inventory availability, ensuring reliable procurement for new production and field service applications.

Q: Are there any mechanical considerations for PCB integration?

A: No. Both inductors use identical radial, horizontal cylinder packaging with matching dimensions. Existing PCB footprints and mounting holes require no modification.
