Equivalent & Substitute Parts for L1007R2R2MPWRT

Part Overview

The L1007R2R2MPWRT is a 2.2 µH unshielded drum core wirewound inductor manufactured by KEMET in the L-PWR series. This surface mount component is designed for applications requiring low inductance values with moderate current handling capabilities. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and design requirements. Substitute components must maintain electrical performance across inductance, current rating, DC resistance, and thermal operating range while conforming to the same physical package dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L1007R2R2MPWRT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 2.2 µH
• Package / Case: 1007 (2518 Metric)
• Core type: Drum core, wirewound, ferrite
• Shielding configuration: Unshielded
• DC Resistance: 70 mOhm
• Operating temperature range: -40°C to 105°C
• Tolerance: ±20%

Allowable Variation:

• Current rating may exceed the original specification (280 mA minimum), provided the substitute part maintains all other electrical and mechanical parameters

The substitute part LBR2518T2R2M from Taiyo Yuden meets all mandatory matching criteria and provides enhanced current handling capability (480 mA versus 280 mA), making it suitable for direct replacement in applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The L1007R2R2MPWRT is classified as obsolete. The LBR2518T2R2M from Taiyo Yuden is classified as not for new designs but remains available in production quantities. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications in restricted substance environments.

For applications currently using the L1007R2R2MPWRT, the LBR2518T2R2M provides direct functional substitution with identical electrical performance across inductance, DC resistance, frequency characteristics, and thermal operating range. The increased current rating of the substitute part (480 mA versus 280 mA) presents no compatibility constraint and may provide additional design margin in current-limited applications.

Physical dimensions, package footprint, and mounting characteristics are identical between both components, enabling direct PCB-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the LBR2518T2R2M replace the L1007R2R2MPWRT in existing designs?

A: Yes. The LBR2518T2R2M is electrically and mechanically equivalent to the L1007R2R2MPWRT across all critical parameters: inductance (2.2 µH), DC resistance (70 mOhm), package dimensions (1007/2518 Metric), operating temperature range (-40°C to 105°C), and frequency characteristics. No circuit modification or PCB redesign is required.

Q: What is the significance of the higher current rating on the substitute part?

A: The LBR2518T2R2M is rated for 480 mA continuous current, compared to 280 mA for the original L1007R2R2MPWRT. This higher rating indicates improved thermal performance and saturation characteristics in the substitute component. Applications operating at or below 280 mA experience no change in performance. Applications requiring current between 280 mA and 480 mA benefit from the substitute's enhanced capability.

Q: Are there packaging differences between these components?

A: Both components use identical package specifications: 1007 (2518 Metric) with dimensions of 0.098" L × 0.071" W (2.50 mm × 1.80 mm) and maximum seated height of 0.079" (2.00 mm). The L1007R2R2MPWRT is supplied in standard packaging, while the LBR2518T2R2M is supplied in tape and reel format. Both are compatible with automated assembly processes.

Q: Do both components meet environmental and compliance requirements?

A: Yes. Both the L1007R2R2MPWRT and LBR2518T2R2M are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.8000. Moisture sensitivity level is 1 (unlimited) for both components, indicating no special handling requirements during storage or assembly.

Q: What is the tolerance specification for inductance?

A: Both components specify ±20% inductance tolerance. This tolerance applies to the nominal 2.2 µH value, resulting in an acceptable inductance range of 1.76 µH to 2.64 µH for either component.
