LPV1620-251KL Equivalent & Substitute Parts

Part Overview

The LPV1620-251KL is a 250 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.5 A continuous current with a maximum DC resistance of 180 mOhm. This through-hole radial component operates across the temperature range of -40°C to 85°C and is designed for applications requiring fixed inductance in compact form factors.

The LPV1620-251KL 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 inductor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPV1620-251KL is determined by the following critical parameters:

• Inductance Value: Must be 250 µH with ±10% tolerance
• Core Type: Ferrite drum core, wirewound construction
• Shielding: Unshielded configuration
• Mounting: Through-hole radial, vertical cylinder orientation
• Operating Temperature Range: -40°C to 85°C minimum
• Current Rating: Must support the application's current requirements
• DC Resistance: Must be compatible with circuit performance specifications
• Compliance: RoHS3 compliant, REACH unaffected status

The RC-8 from Triad Magnetics meets the core substitution criteria across inductance, core material, shielding, mounting type, temperature range, and compliance standards. Variations in current rating and DC resistance are within acceptable engineering tolerances for equivalent component selection.

Parameter Comparison

Engineering Selection Recommendations

The RC-8 (Triad Magnetics) qualifies as a functional equivalent to the LPV1620-251KL based on matching inductance specifications, core material, shielding configuration, and mounting characteristics. Both components maintain identical operating temperature ranges and comply with RoHS3 and REACH regulatory requirements.

The RC-8 is classified as active product status, providing ongoing availability and supply chain continuity compared to the obsolete LPV1620-251KL. The RC-8 is suitable for applications where the 1.25 A current rating and 210 mOhm DC resistance are compatible with circuit design parameters. Applications requiring the full 1.5 A rating of the original part require verification that the RC-8's 1.25 A specification meets operational requirements.

Frequently Asked Questions (FAQ)

Q: Can the RC-8 directly replace the LPV1620-251KL in existing designs?

A: The RC-8 matches the LPV1620-251KL across inductance value, core material, shielding, mounting type, and temperature range. Substitution is valid when the application's current requirement does not exceed 1.25 A and the increased DC resistance of 210 mOhm (versus 180 mOhm maximum) is acceptable for circuit performance.

Q: What are the key differences between these two inductors?

A: The primary differences are current rating (1.5 A versus 1.25 A) and DC resistance (180 mOhm max versus 210 mOhm). Physical dimensions also vary slightly: the RC-8 has a 0.600" diameter and 0.930" height compared to the LPV1620-251KL's 0.630" diameter and 0.787" height. Both maintain identical inductance and tolerance specifications.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the LPV1620-251KL and RC-8 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the inductance test frequency for each part?

A: The LPV1620-251KL is tested at 1 kHz, while the RC-8 is tested at 10 kHz. Both maintain the specified 250 µH inductance value within ±10% tolerance at their respective test frequencies.

Q: Are there any physical installation considerations when substituting the RC-8?

A: The RC-8 has slightly different dimensions than the LPV1620-251KL. Verify that the 0.600" diameter and 0.930" height accommodate the available PCB footprint and component clearance in the target application before implementation.
