Bourns 5722 900µH Toroidal Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5722 is a 900µH unshielded toroidal inductor rated for 3.75A continuous current with 175mOhm maximum DC resistance. This through-hole component operates across the industrial temperature range of -55°C to 105°C and is designed for radial, vertical mounting configurations.

The 5722 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems utilizing this inductor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5722 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 900 µH at 1 kHz test frequency
• Inductance Tolerance: ±15%
• Current Rating: 3.75 A minimum
• DC Resistance: 175 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

The Bourns 5722-RC meets all substitution criteria as a direct electrical and mechanical equivalent. The primary distinction is product status: the 5722 is obsolete while the 5722-RC is active production, and packaging format differs (tape/reel versus bulk).

Engineering Selection Recommendations

The Bourns 5722-RC is the direct substitute for the obsolete Bourns 5722. Both components are electrically and mechanically identical across all specified parameters.

Selection between these parts should be based on:

Product Status: The 5722-RC is in active production, ensuring long-term availability and supply chain stability. The 5722 is obsolete and subject to inventory depletion.

Regulatory Compliance: The 5722-RC meets ROHS3 compliance requirements, while the 5722 is non-compliant. For applications subject to RoHS directives or customer compliance mandates, the 5722-RC is the required choice.

Packaging Format: The 5722 is supplied in bulk packaging; the 5722-RC is supplied in tape/reel format. Packaging selection depends on assembly process requirements and order quantity.

Frequently Asked Questions (FAQ)

Q: Can the 5722-RC directly replace the 5722 in existing designs?

A: Yes. The 5722-RC is electrically and mechanically equivalent to the 5722 across all specified parameters: 900µH inductance, 3.75A current rating, 175mOhm DC resistance, iron powder core, unshielded configuration, through-hole mounting, and -55°C to 105°C operating range.

Q: What is the primary reason to transition from 5722 to 5722-RC?

A: The 5722 is obsolete. The 5722-RC is the active production equivalent, ensuring continued availability and supply chain support. Additionally, the 5722-RC meets ROHS3 compliance, addressing regulatory requirements.

Q: Are there dimensional differences between the 5722 and 5722-RC?

A: Yes. The 5722 has a physical dimension of 0.875" diameter × 0.437" width (22.22mm × 11.10mm). The 5722-RC has a dimension of 2.125" diameter × 0.937" width (53.97mm × 23.80mm). Physical mounting space and PCB layout must accommodate the larger 5722-RC footprint.

Q: What packaging formats are available?

A: The 5722 is supplied in bulk packaging. The 5722-RC is supplied in tape/reel format. Tape/reel packaging is standard for automated assembly processes; bulk packaging is suitable for manual assembly or low-volume applications.

Q: Are there any electrical performance differences?

A: No. Both components share identical electrical specifications: 900µH inductance at ±15% tolerance, 3.75A current rating, 175mOhm maximum DC resistance, and 1 kHz test frequency.
