Bourns 5702 25µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5702 is a 25µH unshielded toroidal inductor rated for 5.5A continuous current with a maximum DC resistance of 14mOhm. This through-hole component features an iron powder core and operates across the temperature range of -55°C to 105°C. The 5702 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 5702 is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 25 µH with ±15% tolerance
• Current rating: 5.5 A minimum
• DC resistance: 14 mOhm maximum
• Core material: Iron powder
• Shielding configuration: Unshielded
• Mounting technology: Through hole
• Package geometry: Radial, vertical orientation
• Operating temperature range: -55°C to 105°C

The 5702-RC variant meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Engineering Selection Recommendations

The Bourns 5702-RC is the direct active equivalent for the obsolete 5702. Both parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on:

Product Status: The 5702-RC carries active product status, ensuring ongoing manufacturer support and availability. The 5702 is obsolete and should not be selected for new designs.

Regulatory Compliance: The 5702-RC meets ROHS3 compliance requirements, while the 5702 does not. For applications subject to RoHS directives, the 5702-RC is the required choice.

Packaging: The 5702-RC is supplied in tray packaging, while the 5702 uses bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can the 5702-RC be used as a direct replacement for the 5702 in existing designs?

A: Yes. The 5702-RC is electrically and mechanically identical to the 5702 across all specified parameters including inductance, current rating, DC resistance, core material, dimensions, and operating temperature range. No circuit modifications are required.

Q: What is the difference between the 5702 and 5702-RC?

A: The primary differences are product status (5702 is obsolete; 5702-RC is active), packaging format (bulk versus tray), and RoHS compliance (5702-RC is ROHS3 compliant; 5702 is not). Electrical and mechanical specifications are identical.

Q: Why should I transition from the 5702 to the 5702-RC?

A: The 5702 is obsolete, which limits future availability and manufacturer support. The 5702-RC is the active equivalent and ensures long-term supply chain continuity. Additionally, the 5702-RC meets current RoHS3 compliance standards.

Q: Are there any compatibility concerns when switching to the 5702-RC?

A: No compatibility concerns exist. Both parts share identical electrical characteristics, DC resistance, current handling capability, and physical dimensions. PCB layout and circuit design remain unchanged.

Q: Does packaging format affect component performance?

A: No. Tray and bulk packaging formats do not affect electrical or mechanical performance. Packaging selection is determined by assembly process requirements and inventory management practices.
