Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5701 is determined by strict equivalence across the following critical parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±15%
• Current rating: 11 A minimum
• DC resistance: 8 mOhm maximum
• Core material: Iron powder
• Shielding configuration: Unshielded
• Mounting type: Through hole
• Package case: Radial, vertical (open)
• Physical dimensions: 0.875" Dia x 0.437" W
• Operating temperature range: -55°C to 105°C

The Bourns 5701-RC meets all substitution criteria as a direct functional equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5701-RC is the direct substitute for the obsolete Bourns 5701. Both components share identical electrical specifications and physical dimensions, ensuring pin-for-pin and form-factor compatibility in existing circuit designs.

The primary distinction between the two parts is product status and regulatory compliance. The 5701-RC is an active product with ROHS3 compliance, whereas the original 5701 is obsolete and RoHS non-compliant. For new designs and ongoing production requiring regulatory adherence, the 5701-RC is the appropriate selection.

Both parts maintain REACH unaffected status and EAR99 export classification. The 5701-RC is supplied in bulk packaging, whereas original 5701 specifications do not specify packaging format.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 5701-RC directly replace the Bourns 5701 in existing applications?

A: Yes. The 5701-RC is electrically and mechanically identical to the 5701. Both components feature 10µH inductance, 11A current rating, 8mOhm DC resistance, iron powder core construction, and identical physical dimensions. Through-hole mounting and radial vertical orientation are preserved.

Q: What is the primary reason to transition from the 5701 to the 5701-RC?

A: The 5701 is classified as obsolete, making long-term availability uncertain. The 5701-RC is an active product with current manufacturing support. Additionally, the 5701-RC achieves ROHS3 compliance, whereas the original 5701 does not.

Q: Are there packaging differences between the 5701 and 5701-RC?

A: The 5701-RC is supplied in bulk packaging. Original 5701 packaging specifications are not detailed in the component data.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the 5701 and 5701-RC operate from -55°C to 105°C.

Q: Are there any compliance or certification differences?

A: The 5701-RC is ROHS3 compliant, while the 5701 is RoHS non-compliant. Both maintain REACH unaffected status and EAR99 export classification.
