Key Parameters

Substitute Part Grouping Explanation

The CMF553K0000BHEB from Vishay Dale qualifies as a substitute based on the following matching parameters:

• Identical resistance value: 3 kOhms
• Identical tolerance: ±0.1%
• Identical temperature coefficient: ±50ppm/°C
• Identical composition: Metal Film
• Identical package type: Axial
• Identical number of terminations: 2
• Identical RoHS3 compliance status
• Identical REACH unaffected status

The CMF553K0000BHEB operates at a higher power rating (0.5W vs 0.25W) and extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C), making it suitable for applications where the RNF14BTC3K00 is specified, with the capability to handle increased thermal stress.
