Key Parameters

Substitute Part Grouping Explanation

The RNMF14FTC2K00 qualifies as a substitute for the RNF18FTC2K00 based on the following electrical and mechanical parameters:

• Identical resistance value: 2 kOhms
• Identical tolerance: ±1%
• Identical composition: Metal Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C to 155°C
• Identical package type: Axial
• Identical features: Flame Retardant Coating, Safety
• Identical RoHS compliance: ROHS3 Compliant

The primary difference is the power rating upgrade from 0.125W to 0.25W, which represents a higher power dissipation capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF18FTC2K00 and RNMF14FTC2K00 maintain Active product status from Stackpole Electronics Inc and satisfy ROHS3 and REACH compliance requirements. The RNMF14FTC2K00 provides increased power dissipation capability at 0.25W compared to the 0.125W rating of the RNF18FTC2K00, while maintaining identical electrical characteristics and operating parameters. Selection between these parts depends on circuit power dissipation requirements and available board space, as both components are mechanically compatible in axial through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC2K00 directly replace the RNF18FTC2K00 in existing designs?

A: Yes. Both resistors share identical resistance, tolerance, temperature coefficient, operating temperature range, and axial package configuration. The RNMF14FTC2K00 offers higher power rating capability, making it suitable for applications where the original part's 0.125W rating may be marginal.

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

A: The power rating differs: RNF18FTC2K00 is rated at 0.125W (1/8W), while RNMF14FTC2K00 is rated at 0.25W (1/4W). All other electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: Both parts use axial package configuration suitable for through-hole mounting. The RNF18FTC2K00 is supplied in Tape & Reel (TR) packaging, while the RNMF14FTC2K00 is supplied in Cut Tape (CT) packaging. This difference affects procurement and handling but does not impact component functionality or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RNF18FTC2K00 and RNMF14FTC2K00 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for electronic component applications.

Q: What determines whether a substitute part is acceptable?

A: Substitution is based on matching resistance value, tolerance, composition, temperature coefficient, operating temperature range, package type, and compliance certifications. Power rating can be upgraded without affecting compatibility, provided the higher rating does not create thermal or space constraints in the application.
