RNF14FTC2M00 Equivalent & Substitute Parts

Part Overview

The RNF14FTC2M00 is a 2 MOhms ±1% 0.25W (1/4W) through-hole resistor with axial leads, manufactured by Stackpole Electronics Inc. This metal film resistor features flame retardant coating and safety construction, designed for applications requiring precision resistance values in compact form factors. The part is currently active in production with ROHS3 compliance and maintains broad operating temperature range from -55°C to 155°C. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC2M00 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 2 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Package/Case: Axial (exact match required)
• Number of Terminations: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

The CMF552M0000FHEB from Vishay Dale qualifies as a substitute because it meets all critical electrical parameters and maintains axial package compatibility. Differences in power rating (0.5W vs 0.25W) and maximum operating temperature (175°C vs 155°C) represent upgrades that do not compromise circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

The CMF552M0000FHEB qualifies as a direct substitute for the RNF14FTC2M00 based on matching electrical specifications and axial package compatibility. Both parts maintain ROHS3 compliance and identical resistance, tolerance, and temperature coefficient values. The CMF552M0000FHEB provides enhanced specifications with higher power rating (0.5W vs 0.25W) and extended maximum operating temperature (175°C vs 155°C), along with additional moisture resistance features. Physical dimensions are comparable within standard axial resistor tolerances. Selection between these parts depends on circuit design requirements, availability, and packaging preferences (Tape & Reel vs Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can the CMF552M0000FHEB replace the RNF14FTC2M00 in all applications?

A: Yes, the CMF552M0000FHEB meets all critical electrical parameters (2 MOhms, ±1% tolerance, ±50ppm/°C temperature coefficient) and maintains axial package compatibility. The higher power rating and extended temperature range represent performance upgrades that do not restrict substitution.

Q: What are the physical dimension differences between these parts?

A: The RNF14FTC2M00 measures 0.093" diameter x 0.250" length (2.35mm x 6.35mm). The CMF552M0000FHEB measures 0.090" diameter x 0.240" length (2.29mm x 6.10mm). Both are standard axial resistor dimensions with minimal variation suitable for PCB layouts designed for either part.

Q: Are there packaging format differences?

A: The RNF14FTC2M00 is supplied in Tape & Reel (TR) format, while the CMF552M0000FHEB is supplied in Cut Tape (CT) format. Both formats are standard for through-hole resistor distribution and do not affect component performance or PCB assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes, both the RNF14FTC2M00 and CMF552M0000FHEB are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry identical HTSUS classification (8533.21.0090).

Q: What is the significance of the moisture resistant feature in the CMF552M0000FHEB?

A: The moisture resistant feature in the CMF552M0000FHEB provides additional environmental protection beyond the flame retardant coating present in both parts. This feature enhances reliability in humid or moisture-prone operating environments without affecting electrical performance or substitution compatibility.
