Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-MFBAF5M0X is determined by the following critical parameters:

• Resistance value: 5 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.333W minimum (1/3W)
• Package: 0402 (1005 Metric) form factor
• Composition: Metal foil or metal element construction
• Application class: Current sense rated
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

The LVT04R0050FER from Ohmite meets all substitution criteria. Both components share identical electrical specifications (5 mOhms, ±1%, 0.333W) and package geometry. The substitute offers an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and maintains equivalent moisture resistance classification.

Parameter Comparison

Engineering Selection Recommendations

The LVT04R0050FER is a direct functional equivalent for the ERJ-MFBAF5M0X. Both components satisfy identical electrical and mechanical requirements for 5 mOhm current sense applications in 0402 package form factor. The substitute maintains ROHS3 compliance and MSL 1 moisture sensitivity classification, ensuring regulatory and environmental compatibility.

The Ohmite LVT04R0050FER offers operational advantages: extended temperature range to 155°C (versus 125°C), improved temperature coefficient (±100ppm/°C versus ±150ppm/°C), and lower seated height (0.014" versus 0.016"). These characteristics provide enhanced performance margin without compromising compatibility.

Selection of the LVT04R0050FER is supported by active product status and established supply availability, eliminating obsolescence risk associated with the original Panasonic component.

Frequently Asked Questions (FAQ)

Q: Can the LVT04R0050FER be used as a direct replacement for the ERJ-MFBAF5M0X?

A: Yes. Both components share identical resistance (5 mOhms), tolerance (±1%), power rating (0.333W), and 0402 package geometry. Electrical and mechanical compatibility is confirmed.

Q: Are there any PCB layout considerations when substituting these parts?

A: The LVT04R0050FER has a lower seated height (0.014" versus 0.016"), which is compatible with existing PCB designs. No layout modifications are required.

Q: What is the significance of the temperature coefficient difference?

A: The LVT04R0050FER exhibits a lower temperature coefficient (±100ppm/°C versus ±150ppm/°C), indicating superior resistance stability across temperature variations. This provides improved measurement accuracy in current sense applications.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: No. The extended range (-55°C to 155°C versus -55°C to 125°C) represents an operational advantage. Applications operating within the original -55°C to 125°C specification remain fully compatible.

Q: Are both components RoHS compliant?

A: Yes. Both the ERJ-MFBAF5M0X and LVT04R0050FER are ROHS3 compliant with MSL 1 moisture sensitivity classification.

Q: What is the availability status of the substitute?

A: The LVT04R0050FER is in active production status with established supply channels, eliminating obsolescence concerns associated with the discontinued ERJ-MFBAF5M0X.
