Parameter Comparison

Engineering Selection Recommendations

CMF601K5000FKBF64 Selection: Select this part for applications where standard tolerance (±1%) and moderate temperature coefficient (±100ppm/°C) specifications are acceptable. Both the main part and substitute maintain active product status with RoHS non-compliant designation and REACH affected classification.

CMF601K5000BEBF Selection: Select this substitute part for applications requiring improved tolerance accuracy (±0.1%) and superior temperature stability (±25ppm/°C). The substitute provides enhanced precision performance while maintaining identical electrical power rating, mechanical package configuration, and operating temperature range. Both parts are manufactured by Vishay Dale within the CMF series.

Frequently Asked Questions (FAQ)

Q: Can CMF601K5000BEBF replace CMF601K5000FKBF64 in existing designs?

A: Yes. Both parts share identical resistance value (1.5 kOhms), power rating (1W), axial package configuration, and physical dimensions (0.145" Dia x 0.344" L).
