744766233 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 744766233 is a 330 µH unshielded drum core wirewound inductor rated for 85 mA with a maximum DC resistance of 14 Ohm, packaged in the 1812 (4532 Metric) surface mount form factor. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same inductance value, current rating, DC resistance, package dimensions, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 744766233 is determined by strict equivalence across the following parameters: inductance value (330 µH), tolerance (±10%), current rating (85 mA), maximum DC resistance (14 Ohm), package form factor (1812 / 4532 Metric), core material (ferrite), shielding configuration (unshielded), and surface mount mounting type. The substitute part CM453232-331KL from Bourns Inc. meets all these criteria and maintains electrical and mechanical compatibility with the original Würth Elektronik component.

Parameter Comparison

Engineering Selection Recommendations

Both the 744766233 and CM453232-331KL are Active product status components with ROHS3 compliance and REACH unaffected status. The Bourns CM453232-331KL provides an extended operating temperature range of -40°C to 125°C compared to the Würth Elektronik component's -40°C to 105°C range. The Bourns part also features a reduced seated height of 0.134" (3.40mm) versus 0.142" (3.60mm), which may provide design flexibility in space-constrained applications. Both components maintain identical electrical specifications and package footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CM453232-331KL directly replace the 744766233 in existing designs? A: Yes. Both components share identical inductance (330 µH), current rating (85 mA), DC resistance (14 Ohm max), package dimensions (1812 / 4532 Metric), and core material specifications. The physical footprint and electrical performance are equivalent.

Q: What are the differences between these two parts? A: The primary differences are the operating temperature range (Bourns extends to 125°C versus Würth's 105°C) and seated height (Bourns 3.40mm versus Würth 3.60mm). Both differences favor the Bourns component in thermal and spatial considerations.

Q: Are there packaging differences between these parts? A: The 744766233 is supplied in Tape & Reel (TR) packaging, while the CM453232-331KL is available in Cut Tape (CT) & Digi-Reel® packaging. Both are surface mount compatible with identical case dimensions.

Q: Do both parts meet the same compliance standards? A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited).
