LPV1823-100ML Equivalent & Substitute Parts

Part Overview

The LPV1823-100ML is a 10 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 8 A continuous current with a maximum DC resistance of 9 mOhm. This component is designed for through-hole mounting in radial, vertical cylinder configuration. The part is currently obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPV1823-100ML is determined by the following core parameters:

• Inductance Value: Must be 10 µH (±20% tolerance acceptable)
• Current Rating: Minimum 8 A continuous current capability
• DC Resistance: Maximum 9 mOhm to maintain equivalent power dissipation characteristics
• Core Material: Ferrite drum core construction
• Mounting Configuration: Through-hole, radial vertical cylinder package
• Compliance: ROHS3 compliance required for regulatory alignment

The substitute part 744750530100 (Würth Elektronik WE-FAMI series) meets these core substitution criteria while offering enhanced specifications in current rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The 744750530100 (Würth Elektronik WE-FAMI) qualifies as a direct substitute for the obsolete LPV1823-100ML based on matching inductance value, tolerance, core material, and mounting configuration. Both components maintain ROHS3 compliance and REACH unaffected status.

The substitute part provides improved specifications: higher current rating (8.9 A versus 8 A) and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). The DC resistance differential (9.5 mOhm versus 9 mOhm maximum) remains within acceptable engineering margins for equivalent circuit performance.

The Würth Elektronik part features shielding, which provides electromagnetic interference mitigation not present in the original unshielded design. This characteristic may be advantageous in noise-sensitive applications or may require circuit layout verification if the original design relied on unshielded operation.

Frequently Asked Questions (FAQ)

Q: Can the 744750530100 directly replace the LPV1823-100ML in existing designs?

A: Yes. Both components share identical inductance values (10 µH), tolerance (±20%), core material (ferrite), and through-hole radial vertical cylinder mounting. Current rating and DC resistance specifications of the substitute meet or exceed the original part requirements.

Q: What is the significance of the shielding difference?

A: The LPV1823-100ML is unshielded, while the 744750530100 is shielded. Shielding reduces electromagnetic field radiation and susceptibility to external interference. If the original circuit design specifically required unshielded operation, the shielded substitute should be evaluated for potential circuit interaction changes.

Q: Are there temperature range considerations for substitution?

A: The substitute part operates across -40°C to 125°C, compared to the original -40°C to 85°C range. This extended range provides greater operational flexibility and is suitable for applications requiring higher temperature performance.

Q: How do the DC resistance values compare?

A: The original part specifies 9 mOhm maximum; the substitute specifies 9.5 mOhm maximum. This 0.5 mOhm difference represents approximately 5.6% variation and remains within acceptable engineering tolerances for equivalent power dissipation characteristics in most applications.

Q: What is the packaging difference between these parts?

A: The LPV1823-100ML is supplied in standard packaging; the 744750530100 is supplied in tray packaging. Tray packaging is standard for production environments and does not affect component electrical or mechanical performance.
