Key Parameters

Substitute Part Grouping Explanation

The RNMF14FTC200K qualifies as a substitute for the RNF18FTC200K based on the following matching parameters:

• Identical resistance value: 200 kOhms
• Identical tolerance: ±1%
• Identical composition: Metal Film
• Identical package type: Axial
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• 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 RNF18FTC200K and RNMF14FTC200K maintain Active product status from Stackpole Electronics Inc and satisfy ROHS3 compliance requirements. The RNMF14FTC200K provides equivalent electrical performance with enhanced power dissipation capability at 0.25W versus 0.125W. Selection between these components depends on circuit power requirements and available board space, as both components are certified for identical operating temperature ranges and feature identical flame retardant safety coatings.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC200K replace RNF18FTC200K in existing designs?

A: Yes. The RNMF14FTC200K provides identical electrical specifications (200 kOhms ±1%, metal film composition, ±50ppm/°C temperature coefficient) and operates across the same temperature range (-55°C ~ 155°C). Both components feature flame retardant coating and maintain ROHS3 compliance.

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

A: The power rating differs: RNF18FTC200K is rated at 0.125W (1/8W), while RNMF14FTC200K is rated at 0.25W (1/4W). The RNMF14FTC200K offers higher power dissipation capability while maintaining all other specifications.

Q: Are there physical dimension differences?

A: Both components use axial package configuration with nearly identical dimensions (RNF18FTC200K: 0.071" Dia x 0.130" L; RNMF14FTC200K: 0.070" Dia x 0.130" L). Physical compatibility is maintained for standard through-hole PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RNF18FTC200K and RNMF14FTC200K are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8533.21.0090).

Q: Which part should be selected for new designs?

A: Component selection depends on circuit power dissipation requirements. If the circuit requires only 0.125W dissipation, either part is suitable. If higher power dissipation is anticipated or required, the RNMF14FTC200K provides additional margin.
