Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC374R is determined by the following critical parameters:

• Resistance value: 374 Ohms (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 (minimum requirement)

The CMF55374R00FHEB from Vishay Dale meets all critical substitution criteria. Both parts share identical electrical specifications and axial package configuration, enabling direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC374R and CMF55374R00FHEB are active production components with ROHS3 compliance and REACH unaffected status. The CMF55374R00FHEB offers an extended operating temperature range to 175°C and includes moisture resistant properties in addition to flame retardant coating. Physical dimensions differ between the two parts, with the CMF55 series featuring a more compact profile. 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 CMF55374R00FHEB be used as a direct replacement for the RNF12FTC374R?

A: Yes. Both parts share identical electrical specifications: 374 Ohms ±1% tolerance, 0.5W power rating, metal film composition, and ±50ppm/°C temperature coefficient. Both are axial through-hole components with ROHS3 compliance. Physical dimensions and packaging formats differ, requiring verification of board layout and assembly equipment compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are physical size (RNF12FTC374R is larger), operating temperature maximum (CMF55 extends to 175°C versus 155°C), moisture resistance feature (CMF55 includes this; RNF12FTC does not), and packaging format (Tape & Reel versus Cut Tape).

Q: Are there any compatibility concerns with axial package dimensions?

A: Axial resistors are mechanically compatible in through-hole applications. However, the CMF55374R00FHEB is physically smaller. Verify that the reduced dimensions do not conflict with board layout spacing, lead bend radius requirements, or automated insertion equipment specifications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical HTSUS codes (8533.21.0090).

Q: Which part should be selected for high-temperature applications?

A: The CMF55374R00FHEB supports operation to 175°C, compared to 155°C for the RNF12FTC374R. For applications approaching or exceeding 155°C, the CMF55 series is the appropriate selection.
