Bourns 5602-RC 10µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5602-RC is a 10µH unshielded drum core wirewound inductor rated for 14A continuous current with 8mOhm maximum DC resistance. This through-hole radial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 5602-RC has reached obsolete product status. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for existing applications and new designs requiring compatible performance characteristics.

Substitute Part Grouping Explanation

Substitute parts for the 5602-RC are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent (Identical Electrical & Mechanical Specifications):

Hammond Manufacturing 1539M02 matches the 5602-RC across all critical parameters: 10µH inductance, 14A current rating, 8mOhm DCR, ±10% tolerance, ferrite drum core construction, and identical physical dimensions (0.830" diameter, 0.910" height). This part provides pin-compatible replacement capability.

Functional Equivalent (Enhanced Performance Parameters):

Bourns 1130-100K-RC maintains core electrical specifications (10µH inductance, ±10% tolerance, ferrite drum core, through-hole radial mounting) but offers improved current handling at 17A versus 14A and reduced DC resistance at 6mOhm maximum versus 8mOhm. Physical dimensions differ (1.100" diameter, 0.840" height), requiring PCB layout verification. This part is suitable for applications where higher current capacity or lower losses provide design margin.

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible Substitution): Select Hammond Manufacturing 1539M02. This part maintains identical electrical specifications (10µH, 14A, 8mOhm) and physical dimensions to the 5602-RC, enabling direct PCB substitution without layout modification. Both parts are ROHS3 compliant and carry active product status, ensuring long-term supply availability.

For Enhanced Performance Applications: Select Bourns 1130-100K-RC when design requirements permit physical dimension changes. The increased current rating (17A versus 14A) and reduced DC resistance (6mOhm versus 8mOhm) provide operational margin in high-current or low-loss applications. Verify PCB footprint compatibility due to larger diameter (1.100" versus 0.830") and slightly reduced height (0.840" versus 0.910"). This part maintains ROHS3 compliance and active product status.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements equivalent to the original 5602-RC specification.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1539M02 replace the Bourns 5602-RC without PCB modification? A: Yes. The 1539M02 maintains identical inductance (10µH), current rating (14A), DC resistance (8mOhm), and physical dimensions (0.830" diameter, 0.910" height), enabling direct pin-compatible substitution.

Q: What are the key differences between the 1539M02 and 1130-100K-RC substitutes? A: The 1539M02 provides identical electrical and mechanical specifications to the 5602-RC. The 1130-100K-RC offers improved current handling (17A versus 14A) and lower DC resistance (6mOhm versus 8mOhm) but requires PCB layout verification due to larger diameter (1.100" versus 0.830").

Q: Are all substitute parts RoHS compliant? A: Yes. The Hammond 1539M02 and Bourns 1130-100K-RC are both ROHS3 compliant, meeting the same environmental standards as the original 5602-RC.

Q: Which substitute should I select for new designs? A: For new designs, either active substitute is acceptable. Use the 1539M02 for form-factor compatibility with existing 5602-RC designs. Use the 1130-100K-RC for applications benefiting from higher current capacity or lower losses, provided PCB layout accommodates the larger package dimensions.

Q: What is the inductance tolerance for substitute parts? A: All substitute parts maintain ±10% inductance tolerance, matching the original 5602-RC specification.
