Key Parameters

Substitute Part Grouping Explanation

The RNMF14FTC100R qualifies as a substitute for the RNF18FTC100R based on the following criteria:

• Identical resistance value: 100 Ohms
• Identical tolerance: ±1%
• Identical composition: Metal Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical package type: Axial
• Identical features: Flame Retardant Coating, Safety
• Identical RoHS compliance: ROHS3 Compliant

The primary difference is the power rating: RNMF14FTC100R is rated at 0.25W (1/4W), which is higher than the RNF18FTC100R at 0.125W (1/8W). This allows the substitute to handle greater power dissipation in the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC100R is suitable as a substitute when circuit design permits the use of a higher power-rated component. Both parts maintain identical electrical characteristics including resistance, tolerance, temperature coefficient, and operating temperature range. Both are ROHS3 compliant and manufactured by Stackpole Electronics Inc. The substitute offers increased power dissipation capability at 0.25W compared to the original 0.125W rating. Selection between these parts depends on the actual power dissipation requirements of the application and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC100R replace RNF18FTC100R in any application?

A: The RNMF14FTC100R can replace the RNF18FTC100R when the circuit design permits a higher power rating. The electrical characteristics are identical, making it suitable for applications where the original 0.125W rating is adequate or where additional power handling margin is beneficial.

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

A: The primary difference is the power rating. The RNF18FTC100R is rated at 0.125W (1/8W), while the RNMF14FTC100R is rated at 0.25W (1/4W). All other electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Yes. The RNF18FTC100R is supplied in Tape & Reel (TR) format, while the RNMF14FTC100R is supplied in Cut Tape (CT) format. Both use axial package configuration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RNF18FTC100R and RNMF14FTC100R are ROHS3 compliant and REACH unaffected, with identical ECCN and HTSUS classifications.

Q: What is the temperature coefficient for both parts?

A: Both parts have a temperature coefficient of ±50ppm/°C and operate across the same temperature range of -55°C to 155°C.
