Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5506-RC is determined by the following critical parameters:

• Inductance value: 150 µH (exact match required)
• Current rating: 4.6 A (minimum threshold)
• DC resistance: 69 mOhm maximum (electrical performance constraint)
• Package / case: Radial, Horizontal Cylinder (mechanical fit requirement)
• Physical dimensions: 0.810" Dia x 1.380" L (PCB layout compatibility)
• Mounting type: Through Hole (assembly process compatibility)
• Shielding: Unshielded (electromagnetic environment requirement)

The Hammond Manufacturing 1538M06 meets all substitution criteria across these parameters, providing functional equivalence for applications currently using the 5506-RC.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M06 be used as a direct replacement for the Bourns 5506-RC?

A: Yes. Both components share identical inductance (150 µH), current rating (4.6 A), DC resistance (69 mOhm max), physical dimensions (0.810" Dia x 1.380" L), and package configuration (radial, horizontal cylinder through-hole). Electrical and mechanical compatibility is confirmed.

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

A: The Bourns 5506-RC specifies ±20% inductance tolerance, while the Hammond 1538M06 specifies ±10%. The tighter tolerance of the 1538M06 may improve circuit performance in applications sensitive to inductance variation.

Q: Are both parts RoHS compliant?

A: Yes. Both the Bourns 5506-RC and Hammond 1538M06 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Will the 1538M06 fit the same PCB footprint as the 5506-RC?

A: Yes. Both components have identical physical dimensions (0.810" Dia x 1.380" L / 20.57mm x 35.05mm) and radial, horizontal cylinder package configuration, ensuring mechanical compatibility with existing through-hole PCB layouts.

Q: Why is the 5506-RC listed as obsolete?

A: The Bourns 5506-RC has reached end-of-life status. The Hammond 1538M06 is an active product offering equivalent electrical and mechanical specifications with continued manufacturing support.
