Engineering Selection Recommendations

Panasonic ERJ-L06KF47MV: This substitute maintains identical electrical specifications to the original TE Connectivity part, including power rating and operating temperature range. The component is active in production with significantly higher inventory availability (15,492 pieces). The ERJ-L06KF47MV features improved temperature coefficient performance (±100ppm/°C versus ±350ppm/°C) and carries AEC-Q200 automotive qualification. RoHS3 compliance is provided. This part is suitable for direct replacement in applications where the original specification is maintained.

Rohm UCR10EVHFSR047: This substitute provides enhanced power rating capability (0.333W versus 0.25W) within the same 0805 package footprint, enabling operation in higher thermal stress environments. The component is active in production with AEC-Q200 automotive qualification and RoHS3 compliance. The extended operating temperature range (-55°C to 155°C) and improved temperature coefficient (0/+250ppm/°C) provide performance advantages. This part is suitable for applications requiring higher power dissipation or extended temperature operation while maintaining the same footprint and resistance value.

Both substitute parts are active products with established supply chains and compliance certifications, providing long-term availability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic ERJ-L06KF47MV be used as a direct replacement for the TE Connectivity 1-1622821-5?

A: Yes. Both parts share identical resistance (47 mOhms), tolerance (±1%), power rating (0.25W), package (0805), and operating temperature range (-55°C to 125°C). The Panasonic part is electrically and mechanically compatible for direct substitution.

Q: What is the primary advantage of the Rohm UCR10EVHFSR047 over the original part?

A: The Rohm part provides higher power rating (0.333W versus 0.25W) and extended maximum operating temperature (155°C versus 125°C), while maintaining identical resistance, tolerance, and package specifications. These enhancements enable operation in more demanding thermal environments.

Q: Are both substitute parts suitable for automotive applications?

A: Yes. Both the Panasonic ERJ-L06KF47MV and Rohm UCR10EVHFSR047 carry AEC-Q200 automotive qualification, making them suitable for automotive-grade applications.

Q: Do the substitute parts have the same physical footprint as the original?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm), ensuring PCB layout compatibility.

Q: What is the difference in temperature coefficient between the parts?

A: The original TE Connectivity part has a temperature coefficient of ±350ppm/°C. The Panasonic substitute offers ±100ppm/°C, and the Rohm substitute offers 0/+250ppm/°C. Lower temperature coefficients indicate better resistance stability across temperature variations.

Q: Are there any compliance or regulatory differences between the parts?

A: Both substitute parts are RoHS3 compliant and REACH unaffected. The original part's compliance status is not specified. Both substitutes provide established regulatory compliance for modern applications.

Q: Which substitute part should be selected for new designs?

A: For applications matching the original specification, either substitute is acceptable. The Panasonic part offers improved temperature coefficient stability. The Rohm part is preferred for applications requiring higher power dissipation or extended temperature operation beyond 125°C.
