Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC2M00 are qualified based on the following electrical and mechanical parameters:

• Resistance Value: Must be 2 MOhms
• Tolerance: Must be ±1%
• Power Rating: Must be 0.5W (1/2W)
• Composition: Must be Metal Film
• Package Type: Must be Axial
• Temperature Coefficient: Must be ±50ppm/°C
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status
• Termination Count: Must be 2 terminations

The CMF552M0000FHEB from Vishay Dale meets all these criteria and qualifies as a direct substitute. Physical dimensions may vary within the axial package specification, and operating temperature range may extend beyond the minimum requirement without affecting substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC2M00 and CMF552M0000FHEB are active production components with full ROHS3 compliance and REACH unaffected status. The CMF552M0000FHEB provides an extended operating temperature range to 175°C and includes moisture resistant properties in addition to flame retardant coating. Selection between these parts should be based on packaging requirements (Tape & Reel versus Cut Tape format) and specific application temperature demands. Both components satisfy the core electrical and mechanical specifications for direct substitution in axial through-hole resistor applications.

Frequently Asked Questions (FAQ)

Q: Can CMF552M0000FHEB replace RNF12FTC2M00 in all applications?

A: Yes, provided the packaging format (Cut Tape versus Tape & Reel) is compatible with your assembly process. Both parts share identical electrical specifications and mechanical compatibility as axial resistors.

Q: What is the difference in physical dimensions between these parts?

A: The RNF12FTC2M00 measures 0.108" Dia x 0.344" L (2.75mm x 8.75mm), while the CMF552M0000FHEB measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). Both are axial package types and fit standard through-hole footprints, though the CMF552M0000FHEB is more compact.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.

Q: Does the extended temperature range of CMF552M0000FHEB affect substitution?

A: No. The extended operating range (-55°C ~ 175°C versus -55°C ~ 155°C) does not restrict substitution. It provides additional operational margin for applications requiring higher temperature tolerance.

Q: What packaging considerations should I account for?

A: The RNF12FTC2M00 is supplied in Tape & Reel format, while CMF552M0000FHEB is supplied in Cut Tape format. Verify your assembly equipment compatibility with the packaging format before selection.
