Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5604-RC are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Electrical Parameters:

• Inductance value: 50 µH
• Inductance tolerance: ±10%
• Current rating: 6.6 A minimum
• DC resistance: 34 mOhm maximum

Mechanical Parameters:

• Core type: Ferrite, unshielded drum core
• Inductor construction: Wirewound
• Mounting: Through hole
• Package configuration: Radial, vertical cylinder
• Physical dimensions: 0.830" diameter, 0.910" height maximum

Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

The 1539M04 manufactured by Hammond Manufacturing is a direct equivalent to the 5604-RC. Both components share identical electrical specifications (50 µH inductance, 6.6 A current rating, 34 mOhm maximum DCR) and mechanical configurations (through-hole, radial vertical cylinder package, 0.830" diameter, 0.910" maximum height).

The 1539M04 is classified as an active product, providing supply chain continuity for applications currently using the obsolete 5604-RC. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacements.

Selection between these parts should be based on availability, lead time, and procurement cost, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 1539M04 be used as a direct replacement for the 5604-RC?

A: Yes. The 1539M04 meets all electrical and mechanical specifications of the 5604-RC, including inductance value, current rating, DC resistance, core type, and physical dimensions. Both components are ROHS3 compliant and REACH unaffected.

Q: Are there any differences in operating temperature ranges between these parts?

A: The 5604-RC specifies an operating temperature range of -55°C to 105°C. The 1539M04 operating temperature range is not provided in the available specifications. Verify operating temperature requirements for your specific application before selection.

Q: Do both parts have identical physical footprints?

A: Yes. Both the 5604-RC and 1539M04 share identical dimensions: 0.830" diameter and 0.910" maximum seated height. They are compatible with the same through-hole PCB layouts and mounting configurations.

Q: What is the significance of the ±10% inductance tolerance?

A: The ±10% tolerance indicates that the actual inductance value may vary between 45 µH and 55 µH. Both the 5604-RC and 1539M04 share this tolerance specification, ensuring equivalent performance in applications where this tolerance is acceptable.

Q: Why is the 5604-RC classified as obsolete?

A: Obsolete status indicates that the manufacturer (Bourns Inc.) has discontinued production. The 1539M04 is an active product from Hammond Manufacturing, providing continued availability for equivalent applications.
