• Inductance tolerance: ±15%
• Current rating: 2.5 A minimum
• DC resistance: 550 mOhm maximum
• Core material: Iron powder
• Shielding configuration: Unshielded
• Mounting type: Through hole
• Package configuration: Radial, vertical (open)
• Operating temperature range: -55°C to 105°C
• Test frequency: 1 kHz

The Bourns 5723-RC meets all specified electrical and mechanical criteria and is classified as a direct substitute within the same product series (5700).

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5723-RC is the direct equivalent substitute for the obsolete Bourns 5723. Both components share identical electrical specifications and mechanical configurations. The primary distinction is product status: the 5723 is obsolete while the 5723-RC remains in active production with significantly higher inventory availability (35,530 units versus 941 units).

For new designs or ongoing production requiring this inductor specification, the 5723-RC is the appropriate selection. The 5723-RC additionally provides ROHS3 compliance, addressing regulatory requirements for new applications. Both components are REACH unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can the 5723-RC be used as a direct replacement for the 5723?

A: Yes. The 5723-RC is electrically and mechanically equivalent to the 5723 across all specified parameters: inductance, current rating, DC resistance, core material, shielding, mounting type, and operating temperature range.

Q: What is the primary reason to transition from the 5723 to the 5723-RC?

A: The 5723 is classified as obsolete. The 5723-RC is the active production equivalent, ensuring long-term supply availability and regulatory compliance (ROHS3).

Q: Are there physical dimension differences between these components?

A: Yes. The 5723 measures 0.875" diameter × 0.437" width (22.22 mm × 11.10 mm), while the 5723-RC measures 2.125" diameter × 0.937" width (53.97 mm × 23.80 mm). Both maintain the same radial, vertical (open) package configuration and are through-hole mounted. PCB layout and mounting hole spacing must be verified for physical compatibility in existing designs.

Q: Do these inductors require any special handling or storage conditions?

A: Moisture sensitivity level is not applicable to either component. Standard component storage practices are sufficient.

Q: What certifications apply to these inductors?

A: Both components are REACH unaffected and classified under ECCN EAR99. The 5723-RC additionally meets ROHS3 compliance requirements.
