LPV1620-101KL Equivalent & Substitute Parts

Part Overview

The LPV1620-101KL is a 100 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 2 A continuous current with a maximum DC resistance of 90mOhm. This through-hole component operates across the temperature range of -40°C to 85°C and is designed for radial vertical cylinder mounting.

The LPV1620-101KL is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this inductor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPV1620-101KL is determined by the following critical parameters:

• Inductance value: 100 µH with ±10% tolerance
• Current rating: minimum 2 A continuous
• DC resistance: maximum 90mOhm
• Core material: Ferrite, unshielded drum core
• Winding configuration: Wirewound
• Mounting: Through hole, radial vertical cylinder package
• Operating temperature: -40°C to 85°C minimum range
• Regulatory compliance: ROHS3 compliant

The AIUR-06-101K from Abracon LLC meets these substitution criteria. It maintains the same inductance value, tolerance, core type, winding configuration, and mounting style. The substitute part exceeds the current rating requirement (2.1 A vs. 2 A) and operates within a compatible temperature range (-25°C to 85°C), though with a narrower lower temperature limit.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-06-101K is a qualified substitute for the obsolete LPV1620-101KL based on electrical and mechanical parameter alignment. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The substitute part maintains identical inductance specifications and core characteristics while providing improved current handling capacity (2.1 A vs. 2 A). The DC resistance of the AIUR-06-101K is 18mOhm higher than the original specification; this difference must be evaluated within the context of the specific circuit application to determine acceptability.

The operating temperature range of the substitute part is narrower at the lower end (-25°C vs. -40°C). Applications requiring operation below -25°C cannot use the AIUR-06-101K without additional thermal analysis.

Physical dimensions differ between the two parts. The AIUR-06-101K has a smaller diameter (0.500" vs. 0.630") and height (0.710" vs. 0.787"), which may affect PCB layout and mechanical fit. Verification of physical compatibility with the existing design is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-06-101K directly replace the LPV1620-101KL in all applications?

A: Direct replacement is possible for applications operating within the temperature range of -25°C to 85°C. Applications requiring operation below -25°C require evaluation of the narrower temperature specification. Physical dimensions must be verified for PCB layout compatibility.

Q: What is the significance of the DC resistance difference between the two parts?

A: The LPV1620-101KL has a maximum DC resistance of 90mOhm, while the AIUR-06-101K has a maximum of 108mOhm. This 18mOhm difference affects power dissipation and thermal performance. Circuit analysis is necessary to determine if this increase is acceptable for the specific application.

Q: Are both parts RoHS compliant?

A: Yes, both the LPV1620-101KL and AIUR-06-101K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What are the physical dimension differences?

A: The LPV1620-101KL measures 0.630" diameter by 0.787" height. The AIUR-06-101K measures 0.500" diameter by 0.710" height. These differences may affect board layout and mechanical clearance requirements.

Q: Why is the LPV1620-101KL classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. The AIUR-06-101K from Abracon LLC provides functional and electrical equivalence for ongoing design support and production requirements.

Q: What parameters must match for substitution eligibility?

A: Critical matching parameters include inductance value (100 µH ±10%), core type (ferrite unshielded drum core), winding configuration (wirewound), mounting style (through hole radial vertical cylinder), and regulatory compliance (ROHS3). Current rating and DC resistance must meet or exceed the original specification requirements.
