Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14CTC2K00 are qualified based on the following criteria:

Resistance value must be 2 kOhms. Package type must be Axial to ensure mechanical and electrical compatibility with existing PCB layouts. Tolerance must be equal to or tighter than ±0.25% to maintain circuit performance specifications. Power rating must be equal to or greater than 0.25W. Composition must be metal film. Operating temperature range must encompass or exceed -55°C to 155°C. RoHS3 compliance is required. All substitute parts identified meet these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both CMF552K0000BEEB and CMF552K0000BHEB are qualified substitutes for the RNF14CTC2K00. The Vishay Dale CMF series parts provide tighter tolerance (±0.1% versus ±0.25%), higher power rating (0.5W versus 0.25W), and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). Both substitute parts include moisture resistant features in addition to flame retardant coating. All three parts are ROHS3 compliant and Active status. Physical dimensions are comparable with minimal variation. Selection between CMF552K0000BEEB and CMF552K0000BHEB depends on temperature coefficient requirements: CMF552K0000BEEB offers ±25ppm/°C while CMF552K0000BHEB matches the original ±50ppm/°C specification.

Frequently Asked Questions (FAQ)

Q: Can CMF552K0000BEEB and CMF552K0000BHEB be used interchangeably with RNF14CTC2K00?

A: Yes. Both parts meet or exceed all critical electrical parameters: 2 kOhms resistance, metal film composition, axial package, and ROHS3 compliance. The substitute parts provide improved tolerance and higher power rating, making them suitable for direct replacement in applications using the RNF14CTC2K00.

Q: What is the difference between CMF552K0000BEEB and CMF552K0000BHEB?

A: Both parts are identical except for temperature coefficient. CMF552K0000BEEB has ±25ppm/°C while CMF552K0000BHEB has ±50ppm/°C. Select CMF552K0000BEEB for applications requiring tighter temperature stability. Select CMF552K0000BHEB if temperature coefficient matching the original RNF14CTC2K00 specification is required.

Q: Are there physical compatibility concerns with the substitute parts?

A: Physical dimensions are comparable. RNF14CTC2K00 measures 0.093" Dia x 0.250" L while substitute parts measure 0.090" Dia x 0.240" L. These minor differences do not affect PCB mounting or circuit board layout compatibility for standard through-hole applications.

Q: Do the substitute parts maintain compliance certifications?

A: Yes. Both CMF552K0000BEEB and CMF552K0000BHEB are ROHS3 compliant and REACH unaffected, matching the compliance status of the RNF14CTC2K00.

Q: What advantage do the substitute parts offer?

A: The Vishay Dale CMF series provides tighter tolerance (±0.1%), higher power dissipation capability (0.5W), moisture resistant coating, and extended operating temperature range (to 175°C). These enhancements support applications with stricter performance requirements while maintaining backward compatibility.
