Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC41K2 is determined by the following critical parameters:

• Resistance value: 41.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (minimum requirement)

The CMF5041K200FHEB from Vishay Dale meets all substitution criteria. Both parts share identical electrical specifications and axial package configuration. Differences in physical dimensions and operating temperature range do not preclude substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC41K2 and CMF5041K200FHEB are Active status components with full ROHS3 compliance and REACH Unaffected certification. Selection between these parts is based on application-specific requirements:

The RNF14FTC41K2 is suitable for applications where the standard operating temperature range of -55°C to 155°C is sufficient and where the larger axial package dimensions are acceptable or preferred for board layout.

The CMF5041K200FHEB is suitable for applications requiring extended temperature operation up to 175°C, compact board space, or where moisture resistance is a design requirement. The smaller physical dimensions of the CMF5041K200FHEB may necessitate layout verification in existing designs.

Both parts maintain identical electrical performance and regulatory compliance status, ensuring functional interchangeability within their respective thermal and spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can CMF5041K200FHEB replace RNF14FTC41K2 in existing designs?

A: Yes, provided the operating temperature does not exceed 155°C and the smaller physical dimensions (0.065" Dia x 0.150" L versus 0.093" Dia x 0.250" L) are compatible with board layout and mechanical constraints. Electrical specifications are identical.

Q: What is the primary difference between these two parts?

A: The CMF5041K200FHEB has a higher maximum operating temperature (175°C versus 155°C), smaller physical dimensions, and includes moisture resistance as an additional feature. All electrical parameters remain identical.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are Active status components with flame retardant coating, safety features, and full ROHS3 compliance. Selection depends on specific thermal and environmental requirements of the application.

Q: Does packaging format affect substitution?

A: The RNF14FTC41K2 is supplied in Tape & Reel (TR) format, while CMF5041K200FHEB is supplied in Cut Tape (CT) format. This affects procurement and handling but does not impact electrical or mechanical compatibility in the final assembly.

Q: What tolerance and temperature coefficient specifications apply to both parts?

A: Both parts maintain ±1% tolerance and ±50ppm/°C temperature coefficient, ensuring equivalent performance stability across the operating temperature range.
