Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC6K34 is determined by the following critical parameters:

• Resistance Value: Must be 6.34 kOhms
• Tolerance: Must be ±1%
• Power Rating: Must be 0.5W (1/2W)
• Composition: Must be Metal Film
• Package Type: Must be Axial (through-hole)
• Temperature Coefficient: Must be ±50ppm/°C
• Regulatory Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The CMF556K3400FHEB from Vishay Dale meets all electrical and mechanical substitution criteria. Both parts share identical resistance, tolerance, power rating, composition, and temperature coefficient specifications. Both are ROHS3 compliant and REACH unaffected. Physical dimensions differ slightly, but both maintain axial package compatibility for standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC6K34 and CMF556K3400FHEB are active production components with full ROHS3 compliance and REACH unaffected status, making either suitable for regulated applications. The CMF556K3400FHEB offers an extended operating temperature range to 175°C compared to 155°C for the RNF12FTC6K34, and includes moisture resistant properties in addition to flame retardant coating. The CMF556K3400FHEB is available in higher inventory (2240 units) versus the RNF12FTC6K34 (766 units). Physical dimensions are smaller for the CMF556K3400FHEB, which may be advantageous for space-constrained PCB layouts. Selection between these parts should be based on specific application requirements regarding temperature exposure, moisture environment, available board space, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the CMF556K3400FHEB directly replace the RNF12FTC6K34 in existing designs?

A: Yes. Both parts share identical electrical specifications (6.34 kOhms ±1%, 0.5W, ±50ppm/°C metal film construction) and axial through-hole package compatibility. The CMF556K3400FHEB has smaller physical dimensions and an extended temperature range, which are compatible with standard through-hole PCB footprints designed for the RNF12FTC6K34.

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

A: The primary differences are physical size (CMF556K3400FHEB is more compact), operating temperature range (CMF556K3400FHEB extends to 175°C versus 155°C), and additional moisture resistant properties on the CMF556K3400FHEB. Electrical performance is identical.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the RNF12FTC6K34 and CMF556K3400FHEB are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: Does packaging format affect substitution compatibility?

A: The RNF12FTC6K34 is supplied in Tape & Reel (TR) format while the CMF556K3400FHEB is supplied in Cut Tape (CT) format. Both packaging formats are standard for through-hole component distribution and do not affect PCB assembly compatibility. Packaging selection depends on manufacturing process requirements and volume considerations.

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

A: The CMF556K3400FHEB is rated to 175°C, providing a 20°C advantage over the RNF12FTC6K34 (155°C maximum). For applications approaching or exceeding 155°C, the CMF556K3400FHEB is the appropriate selection.
