Bourns 5605-RC 100µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5605-RC is a 100µH unshielded drum core wirewound inductor rated for 4.5A continuous current with 72mOhm 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 5605-RC has reached obsolete product status. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for existing applications or new designs requiring compatible performance characteristics.

Substitute Part Grouping Explanation

Substitute parts for the 5605-RC are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent (1539M05): Identical electrical specifications (100µH, 4.5A, 72mOhm DCR) and mechanical form factor. Manufactured by Hammond Manufacturing. Provides pin-for-pin and footprint compatibility with the original 5605-RC.

Enhanced Performance Alternative (1130-101K-RC): Maintains core electrical parameters (100µH inductance, ±10% tolerance, ferrite drum core, through-hole radial mounting) but with improved current handling (9A vs 4.5A) and reduced DC resistance (34mOhm vs 72mOhm). Manufactured by Bourns Inc. Suitable for applications where higher current capacity or lower losses are beneficial. Physical dimensions differ slightly.

Engineering Selection Recommendations

For Direct Replacement: Select 1539M05 (Hammond Manufacturing) when exact electrical and mechanical specifications must be maintained. This part provides identical performance characteristics and form factor compatibility. Both the original 5605-RC and 1539M05 are ROHS3 compliant and REACH unaffected.

For Enhanced Performance Applications: Select 1130-101K-RC (Bourns Inc.) when circuit design permits higher current capacity or when reduced DC resistance losses are advantageous. This part maintains all core electrical parameters while offering improved thermal and current handling characteristics. Verify mechanical fit due to dimensional differences (1.100" diameter vs 0.830" diameter). Both parts maintain ROHS3 compliance and REACH unaffected status.

Both substitute parts are active products with established supply availability, ensuring long-term component sourcing reliability.

Frequently Asked Questions (FAQ)

Q: Can 1539M05 be used as a direct drop-in replacement for 5605-RC? A: Yes. The 1539M05 provides identical inductance (100µH), current rating (4.5A), DC resistance (72mOhm), tolerance (±10%), core type (ferrite drum core), and package configuration (radial through-hole). Physical dimensions are also identical.

Q: What is the primary difference between 1539M05 and 1130-101K-RC? A: Both maintain 100µH inductance and ±10% tolerance. The 1130-101K-RC offers doubled current capacity (9A vs 4.5A) and reduced DC resistance (34mOhm vs 72mOhm). Physical dimensions differ: 1130-101K-RC is larger (1.100" diameter, 0.840" height vs 0.830" diameter, 0.910" height).

Q: Are there mechanical compatibility concerns when substituting with 1130-101K-RC? A: Yes. The 1130-101K-RC has a larger diameter (1.100" vs 0.830") and slightly different height (0.840" vs 0.910"). Verify PCB layout and component spacing accommodate the larger form factor before selection.

Q: Do all three parts meet current regulatory requirements? A: Yes. The 5605-RC (obsolete), 1539M05, and 1130-101K-RC are all ROHS3 compliant and REACH unaffected.

Q: Which substitute should be selected for new designs? A: For new designs, either active part (1539M05 or 1130-101K-RC) is acceptable. Choose 1539M05 for exact performance matching or 1130-101K-RC if enhanced current capacity and lower losses provide circuit benefits.
