Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNMF12FTC130R is determined by the following critical parameters:

• Electrical Equivalence: Resistance value (130 Ohms), tolerance (±1%), and power rating (0.5W/1/2W) must match exactly
• Composition: Metal film construction required for thermal stability and precision
• Package Configuration: Axial through-hole form factor for PCB compatibility
• Temperature Coefficient: ±50ppm/°C specification for circuit performance consistency
• Compliance: ROHS3 compliance and EAR99 classification maintained
• Mechanical Compatibility: Physical dimensions must accommodate standard PCB hole spacing and component placement

The CMF55130R00FHEB from Vishay Dale meets all electrical and functional requirements for direct substitution, with minor dimensional variations within acceptable tolerances for axial resistor applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNMF12FTC130R and CMF55130R00FHEB maintain Active product status with full ROHS3 compliance and REACH unaffected classification. The CMF55130R00FHEB provides an extended operating temperature range to 175°C compared to 155°C for the RNMF12FTC130R, offering additional thermal margin in high-temperature applications. The CMF55 series includes moisture-resistant features beyond the base flame retardant coating. Dimensional differences are minimal and fall within standard PCB design tolerances for axial component placement. Selection between these parts should be based on supply availability, packaging format requirements (Tape & Reel versus Cut Tape), and specific thermal operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can the CMF55130R00FHEB replace the RNMF12FTC130R in existing designs?

A: Yes. Both components share identical electrical specifications (130 Ohms, ±1%, 0.5W, ±50ppm/°C) and axial through-hole package configuration. Dimensional variations (0.093" vs 0.090" diameter; 0.250" vs 0.240" length) are within standard PCB design tolerances for axial resistor placement.

Q: What is the difference in operating temperature range?

A: The RNMF12FTC130R operates from -55°C to 155°C, while the CMF55130R00FHEB extends to 175°C. For applications requiring operation above 155°C, the CMF55 series provides additional thermal headroom.

Q: Are there packaging differences between these parts?

A: The RNMF12FTC130R is supplied in Tape & Reel (TR) format, while the CMF55130R00FHEB is available in Cut Tape (CT) format. Both are suitable for automated assembly; packaging selection depends on production volume and handling requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What additional features does the CMF55130R00FHEB provide?

A: The CMF55 series includes moisture-resistant properties in addition to flame retardant coating, offering enhanced environmental protection compared to the base RNMF specification.
