Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC976R is determined by the following critical parameters:

• Resistance Value: Must be 976 Ohms
• Tolerance: Must be ±1% or tighter
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Must be Metal Film
• Package: Must be Axial Through-Hole configuration
• Temperature Coefficient: Must be ±50ppm/°C or better
• Regulatory Compliance: Must maintain RoHS3 compliance and REACH unaffected status
• Termination Count: Must have 2 terminations (standard axial leads)

The CMF50976R00FHEB from Vishay Dale meets all substitution criteria with identical electrical specifications and compatible mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The CMF50976R00FHEB qualifies as a direct substitute for the RNF14FTC976R based on matching electrical specifications (976 Ohms ±1%, 0.25W, ±50ppm/°C) and identical axial through-hole package configuration. Both components maintain Active product status with full RoHS3 compliance and REACH unaffected certification. The Vishay Dale substitute provides an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and includes moisture-resistant properties as an additional feature. Selection between these components should be based on availability, packaging format preference (Tape & Reel versus Cut Tape), and specific application environmental requirements within the stated operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the CMF50976R00FHEB replace the RNF14FTC976R in all applications?

A: Yes, the CMF50976R00FHEB meets all electrical and mechanical substitution criteria. Both components share identical resistance values (976 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±50ppm/°C), and axial through-hole package configuration. Both maintain RoHS3 compliance and REACH unaffected status.

Q: What are the physical dimension differences between these parts?

A: The RNF14FTC976R measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). The CMF50976R00FHEB measures 0.065" Dia x 0.150" L (1.65mm x 3.81mm). The substitute part is physically smaller, which may affect board layout considerations in space-constrained applications.

Q: Are there packaging format differences?

A: Yes. The RNF14FTC976R is supplied in Tape & Reel (TR) format, while the CMF50976R00FHEB is supplied in Cut Tape (CT) format. Both are standard through-hole component packaging options suitable for automated assembly.

Q: Does the extended temperature range of the substitute part affect compatibility?

A: No. The CMF50976R00FHEB operating range (-55°C ~ 175°C) encompasses the RNF14FTC976R range (-55°C ~ 155°C). The extended upper temperature limit provides additional margin and does not create compatibility issues for applications within the original part's specified range.

Q: Are both parts suitable for safety-critical applications?

A: Both components feature safety-grade construction with flame retardant coating. Regulatory compliance (RoHS3, REACH unaffected) is identical. Application-specific safety requirements should be evaluated against component datasheets and relevant industry standards.
