Bourns 5252 125µH Wirewound Inductor - Equivalent & Substitute Parts

Part Overview

The Bourns 5252 is a 125µH unshielded drum core wirewound inductor rated for 4.6A continuous current with 80mOhm maximum DC resistance. This through-hole axial component operates across -55°C to 105°C and features ferrite core construction with ±20% inductance tolerance. The 5252 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Engineering Selection Recommendations

The Bourns 5252-RC is the direct functional equivalent for the obsolete 5252. Both components share identical electrical specifications and physical form factors. The 5252-RC offers two significant advantages: active product status ensuring continued availability, and ROHS3 compliance meeting current regulatory requirements. The 5252-RC is supplied in bulk packaging versus the original part's standard packaging configuration.

Frequently Asked Questions (FAQ)

Q: Can the 5252-RC be used as a direct replacement for the 5252? A: Yes. The 5252-RC maintains identical inductance (125µH), current rating (4.6A), DC resistance (80mOhm max), core material (ferrite), shielding (unshielded), and physical dimensions (0.500" Dia × 1.250" L). Both components are through-hole axial mounted with -55°C to 105°C operating range.

Q: What is the primary difference between these parts? A: The 5252 is obsolete with non-compliant RoHS status. The 5252-RC is an active product with ROHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Q: Are there packaging differences? A: The 5252-RC is supplied in bulk packaging, while the original 5252 used standard packaging. Both maintain identical component specifications and form factor.

Q: Does the 5252-RC meet the same electrical performance requirements? A: Yes. Inductance tolerance (±20%), self-resonant frequency (2.25MHz), and all current/resistance ratings are identical between both parts.
