Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTR10EVHFSR047 is determined by the following critical parameters:

• Resistance value: 47 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W minimum
• Package: 0805 (2012 metric) form factor
• Composition: Thick film construction
• Temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200 certification
• Application suitability: Current sense capability

The ERJ-6BWFR047V from Panasonic Electronic Components meets all substitution criteria. Both parts share identical electrical specifications, package dimensions, and automotive compliance ratings, enabling direct functional replacement in current sensing circuits.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-6BWFR047V is the qualified substitute for the obsolete LTR10EVHFSR047. Both components carry AEC-Q200 automotive certification and ROHS3 compliance, meeting regulatory and quality requirements for automotive current sensing applications. The Panasonic part maintains active production status, ensuring long-term availability and supply chain continuity. The temperature coefficient difference (±150 ppm/°C versus 0/+200 ppm/°C) falls within acceptable tolerances for current sense applications operating within the specified temperature range. Dimensional compatibility and identical electrical ratings enable direct board-level substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-6BWFR047V replace the LTR10EVHFSR047 in existing designs?

A: Yes. Both parts share identical resistance values, tolerance, power ratings, package dimensions, and AEC-Q200 automotive certification. Direct substitution is supported without circuit modification.

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

A: The LTR10EVHFSR047 specifies ±150 ppm/°C while the ERJ-6BWFR047V specifies 0/+200 ppm/°C. Both values are within acceptable ranges for current sensing circuits operating across the -55°C to 155°C temperature range. The difference does not affect functional compatibility.

Q: Are there packaging differences between these parts?

A: Both parts use the 0805 (2012 metric) package. The LTR10EVHFSR047 is designated as "wide 0805" while the ERJ-6BWFR047V uses standard 0805 dimensions. Dimensional specifications (length, width, height) are compatible for PCB placement and soldering.

Q: What is the product status significance?

A: The LTR10EVHFSR047 is obsolete, meaning Rohm Semiconductor no longer manufactures this part. The ERJ-6BWFR047V maintains active production status, ensuring continued availability and supply chain reliability for new procurement and design support.

Q: Are both parts compliant with automotive and environmental standards?

A: Yes. Both components are AEC-Q200 qualified, ROHS3 compliant, and REACH unaffected. Moisture sensitivity level is MSL 1 (unlimited) for both parts, indicating no special storage or handling requirements.
