Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14BAC2K00 are qualified based on the following criteria:

Electrical Equivalence:

• Identical resistance value: 2 kOhms
• Matching tolerance: ±0.1%
• Metal film composition maintained
• Flame retardant coating and safety features present

Mechanical Compatibility:

• Axial package configuration
• Through-hole termination (2 terminations)
• Physical dimensions compatible with standard PCB layouts

Compliance & Certification:

• ROHS3 compliance maintained
• REACH unaffected status
• Active product status

The substitute parts CMF552K0000BEEB and CMF552K0000BHEB from Vishay Dale meet these criteria. Both are rated at 0.5W (1/2W), which represents a higher power capability than the original 0.25W specification. This upgrade in power rating is permissible as it maintains backward compatibility in applications where the original 0.25W rating is sufficient, while providing additional thermal margin.

Parameter Comparison

Engineering Selection Recommendations

Both CMF552K0000BEEB and CMF552K0000BHEB are qualified substitutes for the RNF14BAC2K00 based on electrical and mechanical equivalence. Selection between these options depends on application-specific requirements:

CMF552K0000BEEB features a temperature coefficient of ±25ppm/°C, providing superior stability across temperature variations compared to the original ±50ppm/°C specification. This option is suitable for precision applications requiring enhanced thermal stability.

CMF552K0000BHEB maintains the ±50ppm/°C temperature coefficient matching the original part, offering direct thermal performance equivalence while providing the additional benefits of higher power rating and extended operating temperature range to 175°C.

Both substitute parts include moisture-resistant features in addition to flame retardant coating, enhancing reliability in humid environments. All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can CMF552K0000BEEB or CMF552K0000BHEB be used as direct replacements for RNF14BAC2K00?

A: Yes. Both substitute parts maintain identical resistance (2 kOhms) and tolerance (±0.1%) specifications. The axial package configuration and through-hole termination are mechanically compatible. The higher power rating (0.5W vs. 0.25W) provides additional thermal capability without affecting circuit performance in applications designed for the original 0.25W part.

Q: What is the difference between the two substitute parts?

A: CMF552K0000BEEB has a temperature coefficient of ±25ppm/°C, while CMF552K0000BHEB has ±50ppm/°C. Both are rated at 0.5W and operate across -55°C to 175°C. Selection depends on whether enhanced temperature stability (BEEB) or thermal coefficient matching (BHEB) is required for the application.

Q: Are there packaging differences between the main part and substitutes?

A: The RNF14BAC2K00 is supplied in Tape & Box (TB) packaging, while both substitute parts use Cut Tape (CT) packaging. Both packaging formats are standard for through-hole axial resistors and do not affect component functionality or PCB assembly compatibility.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. Regulatory and environmental compliance requirements are maintained across the main part and both substitutes.

Q: What is the significance of the moisture-resistant feature on the substitute parts?

A: The substitute parts include moisture-resistant coating in addition to flame retardant coating. This provides enhanced protection in humid or corrosive environments, representing an improvement over the original part specification while maintaining full backward compatibility.
