Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MF1/4DC2R00F are qualified based on the following criteria:

• Identical resistance value: 2 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.25W (1/4W)
• Same composition: Metal Film
• Compatible package: Axial through-hole
• Matching temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C to 155°C
• Equivalent regulatory compliance: ROHS3 Compliant

The RNF14FTD2R00 from Stackpole Electronics Inc meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the MF1/4DC2R00F and RNF14FTD2R00 are active production components with ROHS3 compliance and REACH unaffected status. The MF1/4DC2R00F carries automotive AEC-Q200 qualification. The RNF14FTD2R00 features flame retardant coating and safety designation. Selection between these parts should be based on specific application requirements regarding automotive qualification or flame retardant properties, as both meet the core electrical and mechanical specifications for 2 Ohm ±1% 0.25W axial metal film resistor applications.

Frequently Asked Questions (FAQ)

Q: Can the RNF14FTD2R00 replace the MF1/4DC2R00F in automotive applications?

A: Both parts meet identical electrical specifications (2 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). The MF1/4DC2R00F carries AEC-Q200 automotive qualification, while the RNF14FTD2R00 does not. Application requirements should determine whether AEC-Q200 qualification is mandatory.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The MF1/4DC2R00F measures 0.091" Dia x 0.248" L (2.30mm x 6.30mm), while the RNF14FTD2R00 measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). Both are axial through-hole packages with compatible PCB footprints for standard 0.25W resistor applications.

Q: What is the difference between AEC-Q200 and flame retardant coating?

A: AEC-Q200 is an automotive qualification standard ensuring reliability in automotive environments. Flame retardant coating is a safety feature that reduces flammability. These are distinct specifications; selection depends on whether automotive qualification or flame retardant properties are required.

Q: Are both parts ROHS3 compliant?

A: Yes, both the MF1/4DC2R00F and RNF14FTD2R00 are ROHS3 compliant and REACH unaffected.
