Bourns 5717 500µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5717 is a 500µH unshielded toroidal inductor rated for 4A continuous current with 150mOhm maximum DC resistance. This through-hole component features an iron powder core and operates across the industrial temperature range of -55°C to 105°C. The 5717 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The 5717-RC serves as the direct active substitute, maintaining identical electrical specifications while offering improved compliance status and availability.

Key Parameters

Substitute Part Grouping Explanation

The 5717-RC qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution criteria are determined by the following parameters:

• Inductance value and tolerance (500µH ±15%)
• Current rating (4A minimum)
• DC resistance specification (150mOhm maximum)
• Core material type (Iron Powder)
• Shielding configuration (Unshielded)
• Operating temperature range (-55°C to 105°C)
• Mounting type (Through Hole)
• Package configuration (Radial, Vertical Open)

The 5717-RC maintains all electrical specifications identical to the 5717. Physical dimensions differ between the two parts; however, both conform to the same radial, vertical open package classification suitable for through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

The 5717-RC is the appropriate selection for new designs and production continuity. The original 5717 is obsolete and no longer actively manufactured. The 5717-RC maintains complete electrical and thermal equivalence while offering ROHS3 compliance status, addressing regulatory requirements for modern applications. Both parts are manufactured by Bourns Inc. and share identical core specifications for inductance, current handling, and operating temperature range.

For applications requiring the obsolete 5717, direct substitution with the 5717-RC is electrically and mechanically valid. Physical dimensions differ between the two parts; PCB layout verification is necessary to confirm mechanical fit within the available mounting space.

Frequently Asked Questions (FAQ)

Q: Can the 5717-RC replace the 5717 in existing designs?

A: Yes. The 5717-RC provides complete electrical equivalence across all specified parameters: 500µH inductance, 4A current rating, 150mOhm DC resistance, iron powder core, and -55°C to 105°C operating range. Physical dimensions differ; verify PCB layout accommodates the larger 5717-RC package footprint.

Q: What is the primary difference between the 5717 and 5717-RC?

A: The 5717 is obsolete; the 5717-RC is active production. The 5717-RC achieves ROHS3 compliance, whereas the 5717 is non-compliant. Electrical specifications remain identical.

Q: Are there packaging differences between these parts?

A: Yes. The 5717 uses standard packaging; the 5717-RC uses bulk packaging. Both maintain the radial, vertical open through-hole configuration. Physical dimensions are 0.875" Dia x 0.437" W for the 5717 and 1.812" Dia x 0.750" W for the 5717-RC.

Q: What parameters determine substitution eligibility?

A: Inductance value and tolerance, current rating, DC resistance, core material, shielding type, operating temperature range, mounting type, and package configuration must match. All these parameters are identical between the 5717 and 5717-RC.

Q: Is the 5717-RC suitable for high-reliability applications?

A: The 5717-RC meets ROHS3 compliance requirements. Consult application-specific reliability standards and qualification requirements for your end-use environment.
