LPV2023-100ML Equivalent & Substitute Parts
Part Overview
The LPV2023-100ML is a 10 µH unshielded drum core wirewound inductor rated for 10 A continuous current with 8mOhm maximum DC resistance. Manufactured by Bourns Inc., this through-hole component is designed for radial vertical cylinder mounting in applications requiring fixed inductance values with ferrite core construction.
The LPV2023-100ML is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Substitute Part Grouping Explanation
Substitution eligibility for the LPV2023-100ML is determined by the following critical parameters:
- Inductance Value: Must be 10 µH (matched exactly)
- Current Rating: Must meet or exceed 10 A continuous rating
- DC Resistance: Must not exceed 8mOhm maximum
- Core Type: Ferrite drum core construction
- Shielding Configuration: Unshielded

Engineering Selection Recommendations
The DC780R-103K from API Delevan Inc. is a direct functional substitute for the obsolete LPV2023-100ML. Both components meet ROHS3 compliance and REACH unaffected status requirements.
The DC780R-103K provides performance advantages: higher current rating (11.4 A versus 10 A), tighter inductance tolerance (±10% versus ±20%), and extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C). The DC resistance specification (9mOhm Max) remains within acceptable limits for the application.
Physical dimensions differ slightly: the DC780R-103K measures 0.772" diameter (19.60mm) and 0.831" height (21.10mm), compared to the LPV2023-100ML at 0.787" diameter (20.00mm) and 0.906" height (23.00mm). PCB layout verification is required to confirm mechanical fit.
The DC780R-103K is currently in active production status with substantial inventory availability (500,400 pcs), ensuring supply chain continuity.
Frequently Asked Questions (FAQ)
Q: Can the DC780R-103K directly replace the LPV2023-100ML in existing designs?
A: The DC780R-103K meets all electrical substitution criteria: matched 10 µH inductance, current rating exceeding the 10 A requirement, and DC resistance within specification. Physical dimensions require verification for PCB layout compatibility due to minor size differences.
Q: What is the significance of the inductance tolerance difference?
A: The DC780R-103K features ±10% tolerance versus the LPV2023-100ML's ±20% tolerance. This tighter tolerance provides more precise inductance values, which may improve circuit performance in applications sensitive to inductance variation.
Q: Are there temperature range considerations for substitution?
A: The DC780R-103K operates across -55°C ~ 125°C, exceeding the LPV2023-100ML's -40°C ~ 85°C range. This extended range provides greater operational flexibility for applications in extreme temperature environments.
Q: How do the DC resistance specifications compare?
A: The LPV2023-100ML specifies 8mOhm maximum; the DC780R-103K specifies 9mOhm maximum. This 1mOhm difference is negligible for most applications and remains within acceptable power dissipation limits for the 10 A current rating.
Q: What compliance certifications apply to the substitute part?
A: The DC780R-103K maintains ROHS3 compliance and REACH unaffected status, matching the original component's regulatory requirements.
Q: Are there packaging or inventory considerations?
A: The DC780R-103K is supplied in bulk packaging and is currently in active production with 500,400 pcs available, ensuring reliable supply availability compared to the obsolete LPV2023-100ML.
