Bourns 2124-V Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 2124-V is a 1 mH unshielded toroidal inductor rated for 1.3 A with a maximum DC resistance of 400 mOhm. This through-hole component operates across a temperature range of -55°C to 105°C and is part of the 2100 series. The 2124-V has reached obsolete status, making identification of compatible alternatives essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2124-V is determined by strict equivalence across the following parameters:

• Inductance value: 1 mH
• Inductance tolerance: ±15%
• Current rating: 1.3 A minimum
• DC resistance: 400 mOhm maximum
• Type: Toroidal
• Shielding: Unshielded
• Mounting type: Through hole
• Package configuration: Radial, vertical (open)
• Operating temperature range: -55°C to 105°C
• Physical dimensions: 0.860" Dia x 0.450" W

The 2124-V-RC meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The 2124-V-RC is the direct equivalent for the obsolete 2124-V. Both parts share identical electrical and mechanical specifications, including inductance, current rating, DC resistance, and physical dimensions. The primary distinction is product status: the 2124-V-RC is active and available in bulk packaging, whereas the 2124-V is obsolete.

For new designs or production requiring compliance with modern regulatory standards, the 2124-V-RC is preferred due to its ROHS3 compliance status. The 2124-V is RoHS non-compliant. Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 2124-V-RC directly replace the 2124-V in existing designs?

A: Yes. The 2124-V-RC is electrically and mechanically identical to the 2124-V. All electrical parameters, physical dimensions, and mounting configurations are equivalent. The parts are pin-compatible and footprint-compatible.

Q: What is the difference between the 2124-V and 2124-V-RC?

A: The primary differences are product status and regulatory compliance. The 2124-V is obsolete and RoHS non-compliant. The 2124-V-RC is active, available in bulk packaging, and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: The 2124-V packaging specification is not provided. The 2124-V-RC is supplied in bulk packaging. Both parts use the same radial, vertical (open) case configuration for through-hole mounting.

Q: What inductance tolerance should be expected?

A: Both the 2124-V and 2124-V-RC carry an inductance tolerance of ±15%, measured at 1 kHz.

Q: What is the maximum current these inductors can handle?

A: Both parts are rated for 1.3 A maximum continuous current.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both the 2124-V and 2124-V-RC operate across the temperature range of -55°C to 105°C, making them suitable for industrial and extended-temperature applications.
