Key Parameters

Substitute Part Grouping Explanation

The RHA02533R00FE02 qualifies as a parametric equivalent to the RH02533R00FC02 based on the following critical parameters:

• Electrical Specifications: Identical resistance value (33 Ohms), tolerance (±1%), and power rating (25W)
• Thermal Characteristics: Matching temperature coefficient (±20ppm/°C) and operating temperature range (-55°C ~ 250°C)
• Physical Dimensions: Identical size (1.062" L x 1.080" W) and height (0.561" max seated height)
• Mechanical Interface: Same mounting feature (flanges) and lead style (solder lugs)
• Construction: Both utilize wirewound composition with aluminum housing

The substitution is valid for applications where the electrical load, thermal environment, and mechanical mounting requirements are identical to the original specification.

Parameter Comparison

Engineering Selection Recommendations

The RHA02533R00FE02 is the direct substitute for the RH02533R00FC02 when regulatory compliance is a requirement. The RHA series variant provides ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to environmental regulations. Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility. The RHA02533R00FE02 additionally carries Automotive AEC-Q200 qualification, providing enhanced reliability documentation for automotive and mission-critical applications. Selection between these parts should be based on regulatory requirements and application certification needs rather than electrical or mechanical considerations.
