Key Parameters

Substitute Part Grouping Explanation

The 5711-RC serves as a direct functional equivalent to the 5711. Substitution eligibility is determined by matching the following critical parameters:

• Inductance value: 50 µH at 1 kHz test frequency
• Inductance tolerance: ±15%
• Current rating: 9.5 A minimum
• DC resistance: 12 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 5711-RC maintains identical electrical specifications and mechanical form factor compatibility with the original 5711, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 5711-RC is the appropriate selection for new designs and procurement activities. As an active product within the Bourns 5700 series, the 5711-RC provides continuity of supply and meets current regulatory compliance requirements. The 5711-RC achieves ROHS3 compliance, whereas the original 5711 does not, making it the preferred choice for applications subject to RoHS directives. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 5711-RC be used as a direct replacement for the 5711?

A: Yes. The 5711-RC maintains identical inductance (50 µH), current rating (9.5 A), DC resistance (12 mOhm max), core material (iron powder), and mechanical package configuration (radial, vertical through-hole). Direct substitution is supported without circuit modification.

Q: What is the primary difference between the 5711 and 5711-RC?

A: The 5711 is classified as obsolete, while the 5711-RC is an active product. The 5711-RC also achieves ROHS3 compliance, whereas the 5711 does not. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 5711 is supplied in standard packaging, while the 5711-RC is supplied in bulk packaging. Both maintain the same radial, vertical (open) through-hole configuration and physical dimensions are compatible for PCB mounting.

Q: What compliance certifications apply to the 5711-RC?

A: The 5711-RC is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification.

Q: Is the 5711-RC suitable for the full operating temperature range of the original 5711?

A: Yes. The 5711-RC operates across the identical temperature range of -55°C to 105°C, maintaining inductance specifications across this full range.
