LVM25FVR025E-TR Equivalent & Substitute Parts

Part Overview

The LVM25FVR025E-TR is a 1 watt, 25 milliohm current sense resistor manufactured by Ohmite in a 2512 (6432 Metric) package format. This metal foil chip resistor operates across a temperature range of -55°C to 170°C with ±1% tolerance and ±50ppm/°C temperature coefficient. The component is actively produced and RoHS compliant, designed for precision current sensing applications requiring low resistance values with high accuracy.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVM25FVR025E-TR is determined by the following critical parameters:

• Resistance value: 25 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 170°C (exact match required)
• Composition: Metal Foil or Metal Film (functionally equivalent for current sensing)
• RoHS Compliance: Required

The PE2512FKE7W0R025L qualifies as a substitute because it maintains all critical electrical parameters and mechanical compatibility. The power rating increase from 1W to 2W represents an upgrade that does not compromise functionality in the original application context.

Parameter Comparison

Engineering Selection Recommendations

Both the LVM25FVR025E-TR and PE2512FKE7W0R025L are active production components with current availability. The LVM25FVR025E-TR maintains Ohmite's metal foil construction with 1W power rating. The PE2512FKE7W0R025L provides equivalent electrical performance with increased power capacity (2W) and carries AEC-Q200 automotive qualification, along with ROHS3 compliance and REACH unaffected status.

Selection between these components should be based on application requirements for power dissipation capacity, supply chain availability, and any specific manufacturer qualification requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can PE2512FKE7W0R025L replace LVM25FVR025E-TR in all applications?

A: Yes, provided the application does not require metal foil composition specifically. Both components share identical resistance (25 mOhms), tolerance (±1%), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 170°C), and 2512 package dimensions. The PE2512FKE7W0R025L uses metal film composition and provides higher power rating (2W vs 1W).

Q: Are the physical dimensions compatible?

A: Yes. Both components use the 2512 (6432 Metric) package. Dimensional variations (0.252" vs 0.250" length, 0.126" vs 0.125" width, 0.90mm vs 0.89mm height) fall within standard PCB footprint tolerances for this package class.

Q: What is the significance of AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard. The PE2512FKE7W0R025L carries this certification, indicating it meets automotive reliability and quality requirements. This does not affect substitution eligibility for non-automotive applications.

Q: Does composition difference (Metal Foil vs Metal Film) affect substitution?

A: Both metal foil and metal film compositions are acceptable for current sensing applications when electrical parameters are identical. Composition selection depends on specific application requirements for temperature stability, frequency response, or noise characteristics not specified in the base parameters.
