Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5524-RC is determined by the following critical parameters:

• Inductance Value: 50 µH (exact match required)
• Current Rating: 15 A minimum
• DC Resistance: 13 mOhm maximum
• Mounting Configuration: Through-hole, radial horizontal cylinder
• Physical Dimensions: 1.000" Dia x 1.620" L (25.40mm x 41.15mm)
• Shielding Type: Unshielded
• Inductance Measurement Frequency: 1 kHz

The Hammond Manufacturing 1538M24 meets all substitution criteria. Both components share identical inductance, current rating, DC resistance specification, physical dimensions, and mounting configuration. The substitute maintains through-hole radial horizontal cylinder packaging and unshielded construction.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1538M24 is a direct functional equivalent to the obsolete Bourns 5524-RC. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Hammond 1538M24 carries active product status, ensuring ongoing availability and supply chain support.

The Hammond substitute provides tighter inductance tolerance (±10% versus ±20%), which represents an improvement in component consistency without introducing compatibility concerns. All electrical and mechanical parameters remain within specification for direct substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M24 replace the Bourns 5524-RC in existing designs?

A: Yes. Both inductors share identical inductance value (50 µH), current rating (15 A), DC resistance (13 mOhm max), physical dimensions (1.000" Dia x 1.620" L), and mounting configuration (through-hole radial horizontal cylinder). Direct substitution is electrically and mechanically compatible.

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

A: The Bourns 5524-RC specifies ±20% inductance tolerance, while the Hammond 1538M24 specifies ±10%. The tighter tolerance of the Hammond part provides improved consistency without affecting substitution compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the Bourns 5524-RC and Hammond 1538M24 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the product status difference between these inductors?

A: The Bourns 5524-RC is obsolete, while the Hammond 1538M24 is active. The active status of the Hammond part ensures continued availability and supply chain support for new designs and replacements.

Q: Are the physical dimensions identical?

A: Yes. Both inductors measure 1.000" diameter by 1.620" length (25.40mm x 41.15mm) and use identical radial horizontal cylinder packaging, ensuring direct mechanical compatibility in PCB layouts and enclosures.
