Key Parameters

Substitute Part Grouping Explanation

The Bourns 5715-RC qualifies as a direct substitute based on identical electrical and core specifications. Substitution is valid when the following parameters match:

• Inductance value: 1.6 mH
• Inductance tolerance: ±15%
• Current rating: 1.5 A
• DC resistance: 1.27 Ohm maximum
• Core material: Iron Powder
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Operating temperature range: -55°C to 105°C

The 5715-RC maintains all critical electrical parameters while offering improved product status (Active vs. Obsolete) and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5715-RC is the direct active equivalent for the obsolete 5715 model. Selection of the 5715-RC is supported by:

• Identical electrical specifications across all critical parameters
• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance, meeting current environmental and regulatory requirements
• Maintained through-hole mounting compatibility with existing PCB designs
• Equivalent thermal operating range for drop-in replacement applications

The transition from 5715 to 5715-RC does not require circuit redesign or performance re-evaluation when electrical parameters remain within specified tolerances.

Frequently Asked Questions (FAQ)

Q: Can the 5715-RC replace the 5715 in existing designs?

A: Yes. The 5715-RC maintains identical inductance, current rating, DC resistance, core material, and operating temperature specifications. Through-hole mounting compatibility is preserved.

Q: What is the primary reason to transition from 5715 to 5715-RC?

A: The 5715 is obsolete. The 5715-RC is an active product with guaranteed supply availability and ROHS3 compliance.

Q: Are there physical dimension differences between these parts?

A: Yes. The 5715 measures 0.875" diameter × 0.437" width (22.22mm × 11.10mm), while the 5715-RC measures 1.250" diameter × 0.625" width (31.75mm × 15.88mm). PCB layout verification is required before implementation.

Q: Do the packaging differences affect electrical performance?

A: No. Packaging format (bulk vs. tray) does not affect component electrical characteristics or circuit performance.

Q: Is the 5715-RC suitable for high-temperature applications?

A: Yes. The 5715-RC operates across -55°C to 105°C, matching the original 5715 specification.
