Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5719 is determined by strict equivalence across the following critical parameters:

• Inductance value: 2.25 mH
• Inductance tolerance: ±15%
• Current rating: 1.75 A
• DC resistance: 920mOhm 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 5719-RC meets all electrical and mechanical substitution criteria. Physical dimensions differ between the main part and substitute, but both maintain the same electrical performance specifications and mounting interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5719-RC is the direct substitute for the obsolete Bourns 5719. Both parts are electrically and mechanically equivalent across all specified parameters. The 5719-RC offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the 5719-RC meets ROHS3 compliance requirements, whereas the original 5719 is non-compliant. For new designs or production transitions, the 5719-RC is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 5719-RC be used as a direct replacement for the Bourns 5719?

A: Yes. Both parts share identical electrical specifications: 2.25 mH inductance at ±15% tolerance, 1.75 A current rating, and 920mOhm maximum DC resistance. Both use iron powder cores, are unshielded, and operate across the same temperature range (-55°C to 105°C). Through-hole mounting and radial, vertical (open) package configurations are identical.

Q: What are the physical dimension differences between these parts?

A: The Bourns 5719 measures 0.875" diameter by 0.437" width (22.22mm x 11.10mm). The Bourns 5719-RC measures 1.812" diameter by 0.750" width (46.02mm x 19.05mm). Physical size differences do not affect electrical performance or substitution eligibility.

Q: Why is the original Bourns 5719 listed as obsolete?

A: The Bourns 5719 has been discontinued by the manufacturer. The Bourns 5719-RC is the active product replacement, offering the same electrical functionality with improved compliance status.

Q: Does packaging format affect substitution?

A: The Bourns 5719 uses standard packaging, while the Bourns 5719-RC is supplied in tray packaging. Packaging format does not affect electrical or mechanical compatibility. Component selection should be based on supply chain requirements and handling procedures.

Q: Are there RoHS compliance considerations for substitution?

A: The original Bourns 5719 is RoHS non-compliant. The Bourns 5719-RC is ROHS3 compliant. For applications requiring RoHS compliance, the 5719-RC is the appropriate selection.
