Key Parameters

Substitute Part Grouping Explanation

The CMF5593K100FHEB qualifies as a direct substitute for the RNF14FTD93K1 based on the following critical parameters:

• Resistance Value: Both parts are 93.1 kOhms
• Tolerance: Both maintain ±1% tolerance
• Composition: Both are metal film resistors
• Package Configuration: Both use axial through-hole package
• Compliance: Both are ROHS3 compliant and REACH unaffected
• Termination Count: Both have 2 terminations

The CMF5593K100FHEB provides an upgrade path with increased power rating (0.5W vs 0.25W) and improved temperature coefficient (±50ppm/°C vs ±100ppm/°C), while maintaining identical electrical specifications for resistance and tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTD93K1 and CMF5593K100FHEB are active production components with full ROHS3 compliance and REACH unaffected status, making either suitable for new designs and production applications. The CMF5593K100FHEB offers enhanced performance characteristics including higher power dissipation capability (0.5W vs 0.25W), improved temperature stability (±50ppm/°C vs ±100ppm/°C), and extended operating temperature range (-55°C to 175°C vs -55°C to 155°C). Physical dimensions are comparable with minimal variation, supporting direct board-level substitution. Selection between these parts should be based on application power dissipation requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can CMF5593K100FHEB replace RNF14FTD93K1 in existing designs?
