Parameter Comparison

Engineering Selection Recommendations

Both CRCW08051R05FKTA and CRCW08051R05FKEA are electrically and mechanically equivalent and suitable for direct substitution in automotive applications requiring AEC-Q200 qualified components.

The primary distinction between these parts is compliance status. CRCW08051R05FKEA offers ROHS3 compliance and REACH unaffected status, making it the preferred choice for applications subject to environmental regulations or customer requirements mandating RoHS and REACH compliance. CRCW08051R05FKTA remains suitable for applications where such compliance is not required.

Selection should be based on specific application compliance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051R05FKEA be used as a direct replacement for CRCW08051R05FKTA?

A: Yes. Both parts share identical electrical specifications (1.05 Ohms ±1%, 0.125W), mechanical dimensions (0805 package), and automotive qualification (AEC-Q200). They are electrically and mechanically interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are compliance certifications. CRCW08051R05FKEA is ROHS3 compliant and REACH unaffected, while CRCW08051R05FKTA is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and operate across the -55°C ~ 155°C temperature range required for automotive use.

Q: Does the package type differ between these parts?

A: No. Both parts use the 0805 (2012 Metric) package with identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm).

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For applications requiring RoHS and REACH compliance, use CRCW08051R05FKEA. For applications without such requirements, either part is acceptable based on availability.
