Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC13K3 is determined by the following critical parameters:

• Electrical Specifications: Resistance value (13.3 kOhms), tolerance (±1%), and power rating (0.5W) must be identical
• Composition & Construction: Metal film composition with flame retardant coating required
• Package Configuration: Axial through-hole package mandatory
• Temperature Performance: Temperature coefficient (±50ppm/°C) and operating range compatibility
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The CMF5513K300FHEB from Vishay Dale meets all substitution criteria, maintaining identical electrical and mechanical specifications while offering enhanced moisture resistance and extended operating temperature range to 175°C.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC13K3 and CMF5513K300FHEB are active production components with full ROHS3 compliance and REACH unaffected status. The primary distinction lies in physical dimensions and packaging format. The RNF12FTC13K3 measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm) in Tape & Reel packaging, while the CMF5513K300FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm) in Cut Tape format. The CMF5513K300FHEB provides extended operating temperature capability to 175°C and moisture resistance, making it suitable for applications requiring enhanced environmental performance. Selection should be based on PCB layout constraints, thermal requirements, and packaging logistics.

Frequently Asked Questions (FAQ)

Q: Can the CMF5513K300FHEB replace the RNF12FTC13K3 in existing designs?

A: Yes, provided that PCB layout accommodates the smaller physical dimensions (0.090" diameter × 0.240" length versus 0.108" diameter × 0.344" length). Electrical performance is identical across all critical parameters.

Q: What is the significance of the different packaging formats (Tape & Reel vs. Cut Tape)?

A: Tape & Reel (TR) packaging is optimized for automated assembly processes, while Cut Tape (CT) packaging is suitable for manual assembly or lower-volume production. This distinction affects procurement and assembly workflow but does not impact component performance.

Q: Are there any thermal performance differences between these parts?

A: Both components operate at ±50ppm/°C temperature coefficient. The CMF5513K300FHEB extends the maximum operating temperature to 175°C compared to 155°C for the RNF12FTC13K3, providing additional thermal margin in high-temperature applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RNF12FTC13K3 and CMF5513K300FHEB are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: What does the ±1% tolerance specification mean for circuit design?

A: The ±1% tolerance indicates that the actual resistance value will fall within the range of 13.167 kOhms to 13.433 kOhms. Both parts maintain this specification, ensuring equivalent circuit performance.
