LPV1823-101KL Equivalent & Substitute Parts

Part Overview

The LPV1823-101KL is a 100 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 3 A continuous current with a maximum DC resistance of 90 mOhm. This through-hole component operates across the temperature range of -40°C to 85°C and is designed for radial, vertical cylinder mounting. The part is currently obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitute components for the LPV1823-101KL must satisfy the following electrical and mechanical criteria:

• Inductance value of 100 µH with ±10% tolerance
• Current rating equal to or greater than 3 A
• DC resistance (DCR) at or below 90 mOhm maximum
• Ferrite core, unshielded drum core construction
• Through-hole mounting with radial, vertical cylinder package configuration
• Operating temperature range encompassing -40°C to 85°C minimum
• Inductance measured at 1 kHz test frequency
• ROHS3 compliance

The AIUR-15-101K from Abracon LLC meets all substitution criteria and is classified as an active product with improved current rating and lower DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-15-101K is a direct substitute for the obsolete LPV1823-101KL. Both components are ROHS3 compliant and maintain identical inductance values and tolerances. The substitute part offers improved electrical performance with a higher current rating (3.2 A versus 3 A) and lower DC resistance (82 mOhm versus 90 mOhm maximum). The AIUR-15-101K is an active product with current manufacturing support and inventory availability.

Physical dimensions are compatible, with the substitute part featuring a reduced seated height (20.00 mm versus 23.00 mm), which may provide layout advantages in space-constrained applications. The operating temperature range of the substitute extends to -25°C minimum, which covers the majority of industrial applications, though designs requiring operation below -25°C should retain the original LPV1823-101KL specification if available from legacy inventory.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-15-101K replace the LPV1823-101KL in existing designs?

A: Yes. Both components share identical inductance values (100 µH ±10%), ferrite unshielded drum core construction, through-hole radial vertical cylinder mounting, and ROHS3 compliance. The substitute part meets or exceeds all electrical specifications of the original component.

Q: What are the physical compatibility considerations?

A: Both parts maintain the same diameter (18.00 mm). The AIUR-15-101K has a maximum seated height of 20.00 mm compared to 23.00 mm for the LPV1823-101KL. This 3 mm reduction in height is generally compatible with existing PCB layouts and component spacing. Verify clearance in applications with height-constrained mounting areas.

Q: Are there temperature range limitations with the substitute part?

A: The AIUR-15-101K operates from -25°C to 85°C, compared to -40°C to 85°C for the original part. Applications requiring operation below -25°C should evaluate alternative solutions or confirm that the lower temperature limit does not impact system performance.

Q: How do the electrical performance characteristics compare?

A: The AIUR-15-101K provides superior electrical performance with a current rating of 3.2 A (versus 3 A) and lower DC resistance of 82 mOhm maximum (versus 90 mOhm). These improvements reduce power dissipation and provide additional design margin in current-limited applications.

Q: What is the packaging difference between these components?

A: The LPV1823-101KL uses standard radial vertical cylinder packaging, while the AIUR-15-101K uses radial vertical cylinder (open) packaging. Both are through-hole components with compatible footprints and mounting characteristics.

Q: Is the substitute part currently available?

A: Yes. The AIUR-15-101K is an active product with 1526 pieces in current inventory, ensuring supply continuity for new production and design transitions from the obsolete LPV1823-101KL.
