Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC9K76 are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 9.76 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)

Secondary Compatibility Parameters:

• Power rating: Equal or greater than 0.25W
• Operating temperature range: Equal or greater than -55°C ~ 155°C
• Compliance: ROHS3 Compliant, REACH Unaffected

Two substitute parts meet these criteria with variations in power rating and physical dimensions, enabling selection based on thermal requirements and board layout constraints.

Parameter Comparison

Engineering Selection Recommendations

CMF509K7600FHEB (MFR Recommended Substitute): This part provides direct electrical equivalence to the RNF14FTC9K76 with identical power rating (0.25W), resistance, tolerance, 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) enable space-constrained applications. ROHS3 compliance and REACH unaffected status maintain regulatory alignment. This substitute is suitable for direct replacement in existing designs without thermal or layout modifications.

CMF559K7600FHEB (Upgrade Substitute): This part offers increased power dissipation capability (0.5W versus 0.25W), making it suitable for applications requiring higher thermal headroom or operating at elevated ambient temperatures. Electrical parameters remain identical to the main part. Extended operating temperature range (-55°C ~ 175°C) and moisture-resistant features provide enhanced environmental performance. Slightly larger physical dimensions (0.090" Dia x 0.240" L) require verification of board layout compatibility. ROHS3 compliance and REACH unaffected status maintain regulatory requirements. Select this substitute when thermal margin or environmental protection is a design priority.

Frequently Asked Questions (FAQ)

Q: Can CMF509K7600FHEB be used as a direct replacement for RNF14FTC9K76? A: Yes. Both parts share identical electrical specifications: 9.76 kOhms ±1%, 0.25W power rating, ±50ppm/°C temperature coefficient, and metal film composition. The CMF509K7600FHEB features moisture-resistant construction and extended temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). Physical dimensions differ; verify board layout compatibility before substitution.

Q: When should CMF559K7600FHEB be selected over CMF509K7600FHEB? A: Select CMF559K7600FHEB when the application requires higher power dissipation (0.5W versus 0.25W) or operates at elevated ambient temperatures. Both parts meet the same electrical specifications and compliance requirements. The increased power rating provides thermal margin for high-current or high-temperature environments.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RNF14FTC9K76, CMF509K7600FHEB, and CMF559K7600FHEB are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the impact of physical dimension differences on board design? A: The RNF14FTC9K76 measures 0.093" Dia x 0.250" L. CMF509K7600FHEB is smaller (0.065" Dia x 0.150" L), enabling space optimization. CMF559K7600FHEB (0.090" Dia x 0.240" L) is comparable in size. Verify hole spacing, component clearance, and thermal dissipation paths before substitution in existing PCB layouts.

Q: Do packaging format differences affect component selection? A: RNF14FTC9K76 is supplied in Tape & Reel (TR) format. Both substitute parts use Cut Tape (CT) packaging. Verify procurement and assembly process compatibility with your manufacturing workflow. Electrical and mechanical performance are unaffected by packaging format.

Q: Can these parts be used interchangeably in high-reliability applications? A: All three parts meet ROHS3 compliance and share identical electrical specifications. CMF509K7600FHEB and CMF559K7600FHEB include moisture-resistant features not specified for RNF14FTC9K76. Extended operating temperature ranges on substitute parts provide additional margin. Verify specific application requirements and qualification standards before final selection.
