Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC102R is determined by the following critical parameters:

• Resistance Value: Must be 102 Ohms
• Tolerance: Must be ±1%
• Composition: Must be Metal Film
• Package Type: Must be Axial
• Temperature Coefficient: Must be ±50ppm/°C
• Compliance: Must maintain ROHS3 compliance

The substitute parts identified (CMF55102R00FHEB and CMF50102R00FHEB) satisfy all core electrical and mechanical requirements. Variations in power rating and operating temperature range represent enhancements that do not compromise compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

CMF50102R00FHEB is the direct functional equivalent to RNF14FTC102R. Both components share identical resistance, tolerance, power rating, and operating temperature coefficient. The CMF50102R00FHEB provides an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and includes moisture-resistant features while maintaining full ROHS3 compliance. This part is recommended for applications requiring direct replacement with enhanced environmental protection.

CMF55102R00FHEB is a higher-power variant rated at 0.5W (1/2W) compared to the original 0.25W specification. This part is suitable for applications where the circuit can accommodate increased power dissipation capability or where thermal margin is a design consideration. The CMF55102R00FHEB maintains all other electrical specifications and compliance requirements.

Both substitute parts are manufactured by Vishay Dale and carry active product status with ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can CMF50102R00FHEB be used as a direct replacement for RNF14FTC102R?

A: Yes. Both parts have identical resistance (102 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±50ppm/°C), and package type (Axial). The CMF50102R00FHEB provides extended operating temperature range and moisture resistance as additional features.

Q: What is the difference between CMF55102R00FHEB and CMF50102R00FHEB?

A: The primary difference is power rating. CMF55102R00FHEB is rated at 0.5W (1/2W), while CMF50102R00FHEB is rated at 0.25W (1/4W), matching the original RNF14FTC102R specification. All other electrical parameters are identical.

Q: Are there packaging differences between these parts?

A: Yes. RNF14FTC102R is supplied in Tape & Reel (TR) packaging, while both Vishay Dale substitutes (CMF55102R00FHEB and CMF50102R00FHEB) are supplied in Cut Tape (CT) packaging. Both packaging formats are suitable for through-hole axial component assembly.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. RNF14FTC102R, CMF55102R00FHEB, and CMF50102R00FHEB are all ROHS3 compliant.

Q: What is the operating temperature difference between the original and substitute parts?

A: RNF14FTC102R operates from -55°C to 155°C. Both Vishay Dale substitutes operate from -55°C to 175°C, providing a 20°C extended upper temperature limit.
