Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD60K4 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 60.4 kOhms (exact match required)
• Tolerance: ±1% (maintains precision specification)
• Composition: Metal Film (ensures performance characteristics)
• Package: Axial (mechanical compatibility)
• Termination count: 2 (functional equivalence)

Allowable Variations:

• Power rating: May be equal or higher (0.25W or greater)
• Operating temperature range: May be equal or wider
• Temperature coefficient: May be equal or lower (tighter tolerance acceptable)
• Physical dimensions: Minor variations acceptable within axial package constraints
• Coating features: Flame retardant and safety features maintained or enhanced

The CMF5560K400FHEB qualifies as a substitute based on matching resistance, tolerance, composition, and package type, with enhanced power rating (0.5W vs 0.25W) and improved temperature coefficient performance.

Parameter Comparison

Engineering Selection Recommendations

RNF14FAD60K4 Selection Criteria:

• Primary choice when 0.25W power rating is specified and space constraints are critical
• Preferred for applications with strict form factor requirements
• Suitable for standard operating temperature range up to 155°C
• Active production status ensures long-term availability

CMF5560K400FHEB Selection Criteria:

• Recommended when higher power dissipation margin is required (0.5W rating)
• Preferred for applications requiring extended temperature operation to 175°C
• Superior temperature coefficient (±50ppm/°C) provides enhanced stability
• Moisture-resistant construction adds environmental protection
• Higher inventory availability (2092 units) supports rapid procurement

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets.

Frequently Asked Questions (FAQ)

Q: Can CMF5560K400FHEB replace RNF14FAD60K4 in all applications? A: Yes, within the electrical and mechanical parameters specified. The substitute maintains identical resistance (60.4 kOhms) and tolerance (±1%), with enhanced power rating and temperature range. Physical dimensions are comparable within axial package specifications.

Q: What is the significance of the higher power rating in the substitute part? A: The CMF5560K400FHEB's 0.5W rating provides additional thermal margin compared to the 0.25W specification of the RNF14FAD60K4. This allows operation in higher dissipation environments without thermal stress, though it does not change the electrical performance at equivalent current levels.

Q: Are there packaging differences between these parts? A: Yes. The RNF14FAD60K4 is supplied in Tape & Box (TB) format, while the CMF5560K400FHEB is supplied in Cut Tape (CT) format. Both are axial through-hole components with compatible mechanical interfaces.

Q: How do temperature coefficients affect part selection? A: The CMF5560K400FHEB features a ±50ppm/°C coefficient compared to ±100ppm/°C for the RNF14FAD60K4. Lower temperature coefficient indicates better resistance stability across temperature variations, beneficial for precision applications.

Q: Are both parts compliant with current regulatory standards? A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations for electronic components in global markets.
