Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC825R is determined by the following critical parameters:

• Resistance value: 825 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: RoHS3 Compliant (minimum requirement)

The CMF50825R00FHEB from Vishay Dale meets all electrical and mechanical substitution criteria. Both components share identical resistance, tolerance, power rating, composition, and temperature coefficient specifications. Both maintain RoHS3 compliance and axial package configuration. Physical dimensions differ due to manufacturing design variations, but both are compatible with standard through-hole PCB layouts for axial resistors.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC825R and CMF50825R00FHEB are Active products with full RoHS3 compliance and REACH Unaffected status. Selection between these components should be based on:

• Availability and lead time requirements
• PCB layout constraints related to physical dimensions (RNF14FTC825R: 0.093" Dia x 0.250" L; CMF50825R00FHEB: 0.065" Dia x 0.150" L)
• Operating temperature ceiling (CMF50825R00FHEB supports up to 175°C versus 155°C for RNF14FTC825R)
• Moisture resistance requirements (CMF50825R00FHEB includes moisture resistant feature)
• Packaging format preference (RNF14FTC825R supplied in Tape & Reel; CMF50825R00FHEB supplied in Cut Tape)

Both components satisfy identical electrical specifications and regulatory requirements for direct substitution in 825 Ohm ±1% 1/4W axial resistor applications.

Frequently Asked Questions (FAQ)

Q: Can CMF50825R00FHEB replace RNF14FTC825R in all applications?

A: Yes, for applications requiring 825 Ohm ±1% metal film axial resistors rated at 0.25W. Both components share identical electrical specifications, tolerance, temperature coefficient, and regulatory compliance. Physical dimension differences do not affect electrical performance but may impact PCB layout spacing.

Q: What are the physical dimension differences?

A: RNF14FTC825R measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). CMF50825R00FHEB measures 0.065" Dia x 0.150" L (1.65mm x 3.81mm). The Vishay Dale component is more compact in both diameter and length.

Q: Does the higher operating temperature range of CMF50825R00FHEB affect compatibility?

A: No. The CMF50825R00FHEB supports -55°C ~ 175°C while RNF14FTC825R supports -55°C ~ 155°C. The substitute part's extended upper temperature limit provides equal or greater capability for any application within the original part's temperature range.

Q: Are there packaging differences I should consider?

A: RNF14FTC825R is supplied in Tape & Reel (TR) format. CMF50825R00FHEB is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and volume needs.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are RoHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0090.
