RNF14FTC60R4 Equivalent & Substitute Parts

Part Overview

The RNF14FTC60R4 is a 60.4 Ohms ±1% 0.25W (1/4W) through-hole axial resistor manufactured by Stackpole Electronics Inc. This metal film resistor features flame retardant coating and safety construction, designed for applications requiring precision resistance values in compact form factors. The part is Active status and RoHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts may be required due to inventory availability, packaging format preferences, or performance envelope requirements in specific circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC60R4 is determined by the following critical parameters:

Core Electrical Parameters (Must Match):

• Resistance value: 60.4 Ohms
• Tolerance: ±1%
• Composition: Metal Film
• Temperature Coefficient: ±50ppm/°C

Allowable Variations:

• Power rating may be equal or higher (0.25W or greater)
• Operating temperature range may be equal or extended
• Package format remains Axial (through-hole)
• Physical dimensions may vary within axial form factor constraints

Compliance Requirements:

• RoHS3 compliance maintained
• REACH Unaffected status maintained
• Flame retardant coating and safety features preserved

Two substitute parts meet these criteria: CMF5560R400FHEB (upgraded power rating) and CMF5060R400FHEB (manufacturer-recommended equivalent).

Parameter Comparison

Engineering Selection Recommendations

CMF5060R400FHEB (Manufacturer-Recommended Equivalent): This part is the primary substitute option. It maintains identical electrical specifications (60.4 Ohms ±1%, 0.25W, ±50ppm/°C) and extends the operating temperature range to -55°C ~ 175°C. The addition of moisture-resistant features provides enhanced environmental protection. RoHS3 and REACH compliance are maintained. This part is suitable for direct replacement in applications where the original RNF14FTC60R4 is specified.

CMF5560R400FHEB (Upgraded Power Rating): This part provides the same resistance and tolerance specifications but with doubled power rating (0.5W vs 0.25W). The extended operating temperature range (-55°C ~ 175°C) and moisture-resistant features offer improved performance margins. This substitute is appropriate for applications where thermal headroom or environmental robustness is beneficial, provided circuit board layout accommodates the slightly larger physical dimensions. RoHS3 and REACH compliance are maintained.

Both substitutes are Active status products with full compliance certifications matching the original part.

Frequently Asked Questions (FAQ)

Q: Can CMF5560R400FHEB replace RNF14FTC60R4 in all applications? A: Yes, from an electrical standpoint. The CMF5560R400FHEB maintains the same resistance (60.4 Ohms ±1%) and temperature coefficient (±50ppm/°C). The higher power rating (0.5W vs 0.25W) is a non-limiting upgrade. Physical dimensions differ slightly (0.090" Dia x 0.240" L vs 0.093" Dia x 0.250" L), so verify PCB layout compatibility.

Q: What is the difference between the two substitute parts? A: CMF5060R400FHEB matches the original power rating (0.25W) and is the manufacturer-recommended equivalent. CMF5560R400FHEB provides doubled power capacity (0.5W) for applications requiring additional thermal margin. Both maintain identical resistance, tolerance, and temperature coefficient specifications.

Q: Are there packaging format differences? A: Yes. The original RNF14FTC60R4 is supplied in Tape & Reel (TR) format. Both substitutes (CMF5560R400FHEB and CMF5060R400FHEB) are supplied in Cut Tape (CT) format. Verify your assembly process compatibility with the packaging format change.

Q: Do the substitute parts meet the same compliance requirements? A: Yes. Both CMF5560R400FHEB and CMF5060R400FHEB are RoHS3 compliant and REACH Unaffected, matching the original part's regulatory status.

Q: What is the significance of the extended operating temperature range in the substitutes? A: The substitutes extend the upper operating temperature limit from 155°C to 175°C. This provides additional thermal margin in high-temperature applications but does not affect performance in standard operating conditions.

Q: Are moisture-resistant features a requirement for substitution? A: No. The moisture-resistant coating in the substitute parts is an additional feature that does not prevent substitution. It provides enhanced environmental protection in humid or corrosive environments but is not mandatory for basic electrical equivalence.
