Frequently Asked Questions (FAQ)

Q: Can the 1538M05 be used as a direct replacement for the 5505-RC? A: Yes. Both components share identical inductance (100 µH), current rating (4.9 A), DC resistance (61 mOhm Max), shielding characteristics (unshielded), mounting type (through hole), and physical dimensions (0.810" Dia x 1.120" L). The 1538M05 is electrically and mechanically compatible.

Q: What is the difference in inductance tolerance between these parts? A: The 5505-RC has a tolerance of ±20%, while the 1538M05 has a tolerance of ±10%. The tighter tolerance of the 1538M05 provides more precise inductance values within the specified range.

Q: Are both parts compliant with current environmental regulations? A: Yes. Both the 5505-RC and 1538M05 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the 5505-RC listed as obsolete? A: The 5505-RC is no longer in active production. The 1538M05 serves as the active equivalent, ensuring continued availability and support for this inductance value and current rating.

Q: Will the 1538M05 fit in the same PCB footprint as the 5505-RC? A: Yes. Both components have identical physical dimensions (0.810" Dia x 1.120" L / 20.57mm x 28.45mm) and the same radial, horizontal cylinder package configuration, ensuring direct PCB compatibility.
