Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC5K76 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance value: 5.76 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package type: Axial through-hole
• Temperature coefficient: ±50ppm/°C

Allowable Variations:

• Power rating: Equal or higher than 0.25W
• Operating temperature range: Equal or higher upper limit than 155°C
• Physical dimensions: Axial package form factor maintained
• Compliance certifications: ROHS3 and REACH status maintained

Two substitute parts meet these criteria: CMF505K7600FHEB (manufacturer-recommended direct equivalent) and CMF555K7600FHEB (upgraded power rating variant).

Parameter Comparison

Engineering Selection Recommendations

CMF505K7600FHEB (Manufacturer-Recommended Equivalent): This Vishay Dale part provides direct electrical equivalence to the RNF14FTC5K76 with identical resistance, tolerance, power rating, and temperature coefficient. The extended operating temperature range (-55°C ~ 175°C) provides additional thermal margin. Moisture-resistant construction enhances reliability in humid environments. Smaller physical dimensions (0.065" Dia x 0.150" L) may require PCB layout verification for existing designs. This part is recommended for direct replacement in new designs or when supply of the original part is constrained. ROHS3 and REACH compliance maintained.

CMF555K7600FHEB (Upgraded Power Rating Variant): This Vishay Dale part maintains all electrical specifications while providing doubled power dissipation capability (0.5W vs 0.25W). The higher power rating reduces thermal stress in applications with elevated ambient temperatures or higher current conditions. Extended operating temperature range (-55°C ~ 175°C) and moisture-resistant features provide enhanced environmental performance. Physical dimensions (0.090" Dia x 0.240" L) are comparable to the original part. Selection of this variant is appropriate when thermal margin improvement is required or when standardizing on higher-rated components across a product line. ROHS3 and REACH compliance maintained.

Frequently Asked Questions (FAQ)

Q: Can CMF505K7600FHEB be used as a direct drop-in replacement for RNF14FTC5K76? A: CMF505K7600FHEB is electrically equivalent with identical resistance, tolerance, power rating, and temperature coefficient. Physical dimensions differ (0.065" Dia x 0.150" L vs 0.093" Dia x 0.250" L), requiring PCB layout verification. Axial package form factor is maintained.

Q: What is the difference between CMF505K7600FHEB and CMF555K7600FHEB? A: Both parts share identical electrical specifications (5.76 kOhms ±1%, ±50ppm/°C). The primary difference is power rating: CMF505K7600FHEB is rated 0.25W (1/4W), while CMF555K7600FHEB is rated 0.5W (1/2W). Physical dimensions also differ slightly. Select CMF555K7600FHEB when higher power dissipation capability is required.

Q: Are the substitute parts ROHS3 and REACH compliant? A: Yes. Both CMF505K7600FHEB and CMF555K7600FHEB are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the RNF14FTC5K76.

Q: What is the temperature coefficient specification, and does it differ among these parts? A: All three parts (RNF14FTC5K76, CMF505K7600FHEB, and CMF555K7600FHEB) have a temperature coefficient of ±50ppm/°C, ensuring consistent resistance stability across temperature variations.

Q: Do the substitute parts have moisture-resistant features? A: CMF505K7600FHEB and CMF555K7600FHEB both feature moisture-resistant construction in addition to flame retardant coating. The RNF14FTC5K76 specifies flame retardant coating and safety features without explicit moisture resistance designation.

Q: What is the operating temperature range for each part? A: RNF14FTC5K76 operates from -55°C to 155°C. Both substitute parts (CMF505K7600FHEB and CMF555K7600FHEB) operate from -55°C to 175°C, providing 20°C additional upper temperature margin.
