Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC2K15 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.15 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (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, REACH Unaffected (minimum requirement)

The CMF552K1500FHEB from Vishay Dale meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC2K15 and CMF552K1500FHEB are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The CMF552K1500FHEB offers an extended operating temperature range to 175°C compared to 155°C for the RNF12FTC2K15, and includes moisture-resistant construction. Physical dimensions differ, with the CMF552K1500FHEB being more compact. Selection between these parts should account for available board space, thermal environment requirements, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CMF552K1500FHEB replace the RNF12FTC2K15 in all applications?

A: Yes, provided that the smaller physical dimensions (0.090" Dia x 0.240" L versus 0.108" Dia x 0.344" L) and extended temperature rating of the CMF552K1500FHEB are compatible with your circuit design and assembly requirements.

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 runs. Packaging format selection depends on your manufacturing process capabilities.

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

A: No. Both parts share identical resistance (2.15 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), and temperature coefficient (±50ppm/°C). Electrical performance is equivalent.

Q: Why does the CMF552K1500FHEB have a higher maximum operating temperature?

A: The CMF552K1500FHEB is rated to 175°C versus 155°C for the RNF12FTC2K15. This extended range reflects the design and material specifications of the Vishay Dale part and may provide additional thermal margin in high-temperature applications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the RNF12FTC2K15 and CMF552K1500FHEB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
