Bourns 5254 250µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5254 is a 250µH unshielded drum core wirewound inductor rated for 2.5A continuous current with a maximum DC resistance of 170mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in the 250µH range with moderate current handling.

The 5254 carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement. The substitute part 5254-RC provides functional continuity with improved compliance status while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 5254-RC qualifies as a direct substitute based on strict electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

Inductance value matches exactly at 250µH with identical ±20% tolerance. Current rating remains constant at 2.5A. DC resistance specification is identical at 170mOhm maximum. Core material, shielding configuration, and self-resonant frequency are unchanged. Physical dimensions and axial through-hole mounting remain identical. Operating temperature range is preserved across -55°C to 105°C.

The primary distinction between these parts is product status and compliance certification. The 5254 is obsolete and RoHS non-compliant, while the 5254-RC is active and ROHS3 compliant. Packaging differs between the original (standard) and substitute (bulk), but this does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 5254-RC is the appropriate selection for new designs and ongoing procurement. All electrical and mechanical parameters are identical to the 5254, ensuring direct functional compatibility in existing circuit applications. The 5254-RC maintains active product status with manufacturer support and availability.

The 5254-RC carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution. The original 5254, classified as obsolete and RoHS non-compliant, should be replaced in active designs and procurement cycles.

Both parts share identical REACH and ECCN classifications, indicating no change in export control or chemical substance restrictions. Packaging format differs (standard versus bulk), but this distinction does not affect electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the 5254-RC be used as a direct replacement for the 5254 in existing designs?

A: Yes. The 5254-RC is electrically and mechanically identical to the 5254. All critical parameters including inductance, current rating, DC resistance, core material, dimensions, and operating temperature range are unchanged. The substitute part fits the same PCB footprint and performs identically in circuit applications.

Q: What is the primary reason to transition from the 5254 to the 5254-RC?

A: The 5254 is obsolete and RoHS non-compliant. The 5254-RC is an active product with ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and manufacturing.

Q: Are there differences in packaging between these parts?

A: The 5254 uses standard packaging while the 5254-RC is supplied in bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

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

A: Yes. Both the 5254 and 5254-RC operate from -55°C to 105°C, maintaining identical thermal performance specifications.

Q: Is the physical size identical between the 5254 and 5254-RC?

A: Yes. Both parts measure 0.440" diameter by 1.250" length (11.18mm x 31.75mm) and use axial through-hole mounting, ensuring identical PCB layout compatibility.

Q: What compliance certifications apply to the 5254-RC?

A: The 5254-RC is ROHS3 compliant and REACH unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.
