Substitute Part Grouping Explanation

Substitution for the LVR03R0200FE70 is determined by strict equivalence across the following parameters:

• Resistance value: 20 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Package configuration: Axial through-hole
• Physical dimensions: 0.205" Dia × 0.560" L (5.21mm × 14.22mm)
• Operating temperature capability: minimum -55°C to 275°C
• RoHS3 compliance requirement
• Current sense application suitability

The MR3FT20L0 meets all substitution criteria. While composition differs (metal foil versus wirewound), both technologies satisfy the electrical and mechanical requirements for this application category.

Parameter Comparison

Engineering Selection Recommendations

The MR3FT20L0 is the direct substitute for the LVR03R0200FE70. Both parts maintain identical electrical specifications (20 mOhms ±1% at 3W) and physical dimensions required for axial through-hole mounting. The MR3FT20L0 is currently in active production status with 4752 units available in inventory, compared to the obsolete LVR03R0200FE70 with 831 units remaining.

Both parts satisfy ROHS3 compliance requirements. The MR3FT20L0 offers additional features including non-inductive and non-magnetic construction. The operating temperature range of the MR3FT20L0 extends to -55°C minimum, which covers the majority of industrial applications; the LVR03R0200FE70 extends to -65°C minimum for specialized low-temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the MR3FT20L0 directly replace the LVR03R0200FE70 in existing designs?

A: Yes. Both parts share identical resistance (20 mOhms), tolerance (±1%), power rating (3W), package type (axial), and physical dimensions (0.205" Dia × 0.560" L). Electrical and mechanical compatibility is confirmed.

Q: What is the difference between wirewound and metal foil composition?

A: Both compositions meet the specified electrical parameters for this application. Metal foil construction in the MR3FT20L0 provides non-inductive and non-magnetic characteristics. Wirewound construction in the LVR03R0200FE70 is the original design. Selection depends on application-specific requirements for inductance and magnetic properties.

Q: Does the MR3FT20L0 operate at the same temperature extremes as the LVR03R0200FE70?

A: The MR3FT20L0 operates from -55°C to 275°C, while the LVR03R0200FE70 operates from -65°C to 275°C. The MR3FT20L0 is suitable for applications requiring operation above -55°C. Applications requiring operation below -55°C require the LVR03R0200FE70 or alternative parts rated to -65°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the LVR03R0200FE70 and MR3FT20L0 are ROHS3 compliant.

Q: What is the current availability status?

A: The MR3FT20L0 is in active production with 4752 units in stock. The LVR03R0200FE70 is obsolete with 831 units remaining in inventory.
