Bourns 5707 75µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5707 is a 75µH unshielded toroidal inductor rated for 5A continuous current with a maximum DC resistance of 40mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 5707 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The 5707-RC serves as the direct active substitute, maintaining identical electrical specifications while offering improved compliance status and expanded inventory availability.

Key Parameters

Substitute Part Grouping Explanation

The 5707-RC qualifies as a direct substitute for the 5707 based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Inductance value and tolerance (75µH ±15%)
• Current rating (5A minimum)
• DC resistance specification (40mOhm maximum)
• Core material type (Iron Powder)
• Shielding configuration (Unshielded)
• Mounting type (Through Hole)
• Package configuration (Radial, Vertical Open)
• Operating temperature range (-55°C to 105°C)

The 5707-RC maintains all specified electrical characteristics and mechanical compatibility with the original 5707, with the distinction that 5707-RC is actively manufactured and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

The 5707-RC is the appropriate selection for new designs and component replacement applications. As an active product with RoHS3 compliance, the 5707-RC meets current regulatory requirements and ensures long-term supply chain availability. The original 5707, classified as obsolete, should be replaced with the 5707-RC in all applications where component refresh or new procurement is required. Both parts maintain identical electrical performance and mechanical compatibility, with the 5707-RC offering superior compliance status and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5707-RC be used as a direct replacement for the 5707? A: Yes. The 5707-RC maintains identical inductance (75µH ±15%), current rating (5A), DC resistance (40mOhm max), core material (iron powder), and mounting configuration (through-hole radial vertical). All electrical and mechanical parameters are equivalent.

Q: What is the primary difference between the 5707 and 5707-RC? A: The 5707 is obsolete and RoHS non-compliant, while the 5707-RC is an active product with RoHS3 compliance. Electrical specifications and physical dimensions remain functionally equivalent for circuit operation.

Q: Are there physical dimension differences between these parts? A: Yes. The 5707 has a diameter of 0.875" (22.22mm) with a width of 0.437" (11.10mm), while the 5707-RC has a diameter of 1.125" (28.58mm) with a width of 0.562" (14.27mm). PCB layout and mounting clearance must accommodate the larger 5707-RC footprint.

Q: Which part should be specified for new designs? A: The 5707-RC should be specified for all new designs. As an active, RoHS3-compliant product, it ensures regulatory compliance and supply chain continuity.

Q: Are both parts suitable for the same temperature operating range? A: Yes. Both the 5707 and 5707-RC operate across -55°C to 105°C, providing equivalent thermal performance.
