Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVR03R0150FE70 is determined by strict equivalence across the following critical parameters:

• Resistance value: 15 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Package configuration: Axial through-hole
• Physical dimensions: 0.205" Dia x 0.560" L (5.21mm x 14.22mm)
• Termination count: 2
• Operating temperature range: minimum -55°C to maximum 275°C
• Current sense application suitability
• Moisture resistance capability
• RoHS3 compliance

The MR3FT15L0 from Stackpole Electronics Inc meets all substitution criteria. While the composition differs (metal foil versus wirewound), both constructions satisfy the electrical and mechanical requirements for this application category.

Parameter Comparison

Engineering Selection Recommendations

The MR3FT15L0 is the qualified substitute for the LVR03R0150FE70. Both parts maintain identical electrical specifications (15 mOhms ±1% at 3W) and physical form factor (axial, 0.205" Dia x 0.560" L). Both achieve ROHS3 compliance and support current sense applications with moisture resistance.

The MR3FT15L0 carries active product status, ensuring long-term availability and supply chain continuity. The operating temperature range of -55°C to 275°C covers the majority of applications; designs requiring operation below -55°C must evaluate the original LVR03R0150FE70 specification of -65°C minimum.

Frequently Asked Questions (FAQ)

Q: Can the MR3FT15L0 directly replace the LVR03R0150FE70 in existing designs?

A: Yes. Both parts share identical resistance (15 mOhms), tolerance (±1%), power rating (3W), axial package configuration, and physical dimensions (0.205" Dia x 0.560" L). PCB footprints and circuit performance remain unchanged.

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

A: The LVR03R0150FE70 uses wirewound construction; the MR3FT15L0 uses metal foil construction. Both compositions meet the specified electrical parameters and current sense application requirements. Metal foil construction in the MR3FT15L0 provides non-inductive and non-magnetic characteristics.

Q: Are there temperature range limitations when substituting?

A: The MR3FT15L0 operates from -55°C to 275°C, while the original part operates from -65°C to 275°C. Applications requiring operation below -55°C must retain the LVR03R0150FE70 or identify alternative solutions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LVR03R0150FE70 and MR3FT15L0 are ROHS3 compliant. The MR3FT15L0 additionally carries REACH Unaffected status.

Q: What packaging formats are available?

A: The LVR03R0150FE70 is supplied in Cut Tape (CT) packaging. The MR3FT15L0 is supplied in Tape & Reel (TR) packaging. Both formats are standard for through-hole axial resistors and accommodate different assembly processes.
