Equivalent & Substitute Parts for 5608-RC

Part Overview

The Bourns 5608-RC is a 1 mH unshielded drum core wirewound inductor rated for 1.3 A with a maximum DC resistance of 801 mOhm. 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 5608-RC is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5608-RC is determined by the following critical parameters: inductance value (1 mH), core material (ferrite), shielding configuration (unshielded), mounting type (through hole), and operating temperature range (-55°C to 105°C). Current rating and DC resistance are secondary selection criteria that influence application suitability.

Two substitute parts meet the primary substitution criteria:

Direct Equivalent (1539M08): Matches all critical parameters including inductance, core type, shielding, mounting, temperature range, current rating (1.3 A), and DC resistance (801 mOhm). Manufactured by Hammond Manufacturing with active product status.

Functional Substitute (1130-102K-RC): Matches inductance, core type, shielding, mounting, and temperature range. Differs in current rating (2 A vs. 1.3 A) and DC resistance (426 mOhm vs. 801 mOhm), providing enhanced current handling capability. Manufactured by Bourns Inc. with active product status.

Parameter Comparison

Engineering Selection Recommendations

The 1539M08 (Hammond Manufacturing) serves as the direct equivalent replacement for the obsolete 5608-RC. Both components share identical electrical specifications (1 mH inductance, 1.3 A current rating, 801 mOhm DC resistance) and mechanical form factors (radial vertical cylinder configuration). The 1539M08 maintains active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The 1130-102K-RC (Bourns Inc.) functions as a functional substitute where circuit design permits higher current capacity. This part reduces DC resistance to 426 mOhm and increases current rating to 2 A while maintaining the same 1 mH inductance and ferrite core construction. The 1130-102K-RC is suitable for applications where lower resistive losses or higher current margins are beneficial. Package dimensions differ slightly (radial configuration without specified vertical cylinder orientation), requiring mechanical fit verification in existing PCB layouts.

Both substitute parts carry ROHS3 compliance and active manufacturing status, supporting procurement continuity for designs transitioning from the obsolete 5608-RC.

Frequently Asked Questions (FAQ)

Q: Can the 1539M08 be used as a direct replacement for the 5608-RC without circuit modification?

A: Yes. The 1539M08 matches all critical electrical parameters (1 mH inductance, 1.3 A current rating, 801 mOhm DC resistance) and mechanical specifications (radial vertical cylinder package). No circuit redesign is required.

Q: What is the primary difference between the 1539M08 and 1130-102K-RC?

A: The 1130-102K-RC provides higher current capacity (2 A vs. 1.3 A) and lower DC resistance (426 mOhm vs. 801 mOhm) while maintaining the same 1 mH inductance. Both are ferrite core, unshielded, through-hole components. Package dimensions differ slightly.

Q: Is the 1130-102K-RC compatible with existing PCB layouts designed for the 5608-RC?

A: The 1130-102K-RC has different physical dimensions (1.100" diameter vs. 0.830" diameter for the 5608-RC). PCB footprint and mounting hole spacing must be verified before substitution. The radial package configuration is compatible with through-hole assembly processes.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 1539M08 and 1130-102K-RC are ROHS3 compliant, meeting regulatory requirements for restricted substances.

Q: What is the operating temperature range for the 1539M08?

A: Operating temperature specifications are not provided in the available technical data for the 1539M08. The 1130-102K-RC operates across -55°C to 105°C, matching the original 5608-RC range.
