Bourns 5626-RC 100µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5626-RC is a 100µH unshielded drum core wirewound inductor rated for 14A continuous current with 18mOhm maximum DC resistance. This through-hole radial component is designed for applications requiring stable inductance values across the -55°C to 105°C operating temperature range. The 5626-RC series is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the Bourns 5626-RC is determined by the following critical parameters:

Inductance value: 100 µH (exact match required)
Current rating: minimum 14 A continuous
DC resistance: maximum 18 mOhm
Core type: Ferrite, unshielded drum core
Mounting: Through hole, radial vertical cylinder configuration
Package dimensions: 1.500" diameter (38.10mm)
Tolerance: ±10%
Operating temperature range: -55°C ~ 105°C

Two substitute parts meet these criteria with varying performance characteristics:

Direct Equivalent (1539M26): Identical electrical specifications and physical dimensions. Manufactured by Hammond Manufacturing. Active product status.

Functional Equivalent (1140-101K-RC): Matches inductance, core type, and mounting configuration. Reduced current rating (10.5A vs 14A) and increased DC resistance (25mOhm vs 18mOhm). Manufactured by Bourns Inc. Active product status.

Engineering Selection Recommendations

For Direct Replacement (1539M26): This Hammond Manufacturing inductor provides identical electrical and mechanical specifications to the obsolete 5626-RC. It maintains the 14A current rating, 18mOhm DC resistance, and 1.500" seated height. Both components are ROHS3 compliant and REACH unaffected. This part is the preferred choice for applications requiring exact performance matching.

For Functional Substitution (1140-101K-RC): This Bourns alternative maintains the same inductance value, core type, and mounting configuration. The reduced current rating (10.5A) and increased DC resistance (25mOhm) make this suitable only for applications where the circuit current does not exceed 10.5A and where the additional 7mOhm resistance is acceptable. The reduced seated height (1.030" vs 1.500") may affect PCB layout compatibility. Both components are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the 1140-101K-RC be used in place of the 5626-RC in all applications?

A: No. The 1140-101K-RC has a lower current rating (10.5A vs 14A) and higher DC resistance (25mOhm vs 18mOhm). Use only in circuits where the maximum current does not exceed 10.5A and where the increased resistance is acceptable for the application.

Q: What is the primary difference between the two substitute parts?

A: The 1539M26 is a direct electrical and mechanical equivalent with identical current rating and DC resistance. The 1140-101K-RC is a functional equivalent with reduced current capacity and increased resistance, plus a shorter seated height.

Q: Are both substitute parts compliant with current regulations?

A: Yes. Both the 1539M26 and 1140-101K-RC are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 5626-RC.

Q: Does the height difference between the 1140-101K-RC (1.030") and the original part (1.500") affect compatibility?

A: The reduced height may require PCB layout verification. Ensure the shorter component does not create clearance issues with adjacent components or enclosure constraints in your design.

Q: What is the inductance tolerance for all three parts?

A: All three inductors maintain ±10% inductance tolerance at 1 kHz test frequency.
