Substitute Part Grouping Explanation

The RNMF14FTC6K80 qualifies as a direct substitute for the RNF18FTC6K80 based on the following matching parameters:

• Resistance value: 6.8 kOhms (identical)
• Tolerance: ±1% (identical)
• Composition: Metal Film (identical)
• Temperature Coefficient: ±50ppm/°C (identical)
• Operating Temperature Range: -55°C ~ 155°C (identical)
• Features: Flame Retardant Coating, Safety (identical)
• Package Type: Axial (identical)
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected (identical)

The primary difference is the power rating upgrade from 0.125W to 0.25W, which represents a higher capability within the same electrical and mechanical envelope. The RNMF14FTC6K80 belongs to the RNMF (Mini) series and is supplied in Cut Tape (CT) packaging versus Tape & Reel (TR) for the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF18FTC6K80 and RNMF14FTC6K80 maintain Active product status and satisfy ROHS3 and REACH compliance requirements. The RNMF14FTC6K80 provides increased power dissipation capability at 0.25W compared to the 0.125W rating of the RNF18FTC6K80, making it suitable for applications requiring higher thermal headroom within the same electrical specification. Selection between these parts should be based on circuit power requirements and packaging format availability. Both components are manufactured by Stackpole Electronics Inc and share identical electrical characteristics including resistance, tolerance, temperature coefficient, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC6K80 replace the RNF18FTC6K80 in existing designs?

A: Yes. The RNMF14FTC6K80 is electrically and mechanically compatible. Both parts share identical resistance (6.8 kOhms), tolerance (±1%), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part provides higher power rating (0.25W versus 0.125W), which is a capability upgrade that does not compromise circuit function.

Q: What is the difference in physical dimensions between these parts?

A: Both parts use axial package configuration with nearly identical dimensions. The RNF18FTC6K80 measures 0.071" Dia x 0.130" L (1.80mm x 3.30mm), while the RNMF14FTC6K80 measures 0.070" Dia x 0.130" L (1.78mm x 3.30mm). These dimensions are functionally equivalent for PCB layout and mounting purposes.

Q: Are there packaging format differences between these parts?

A: Yes. The RNF18FTC6K80 is supplied in Tape & Reel (TR) format, while the RNMF14FTC6K80 is supplied in Cut Tape (CT) format. Packaging format selection depends on assembly process requirements and order quantity considerations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RNF18FTC6K80 and RNMF14FTC6K80 are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for electronic component applications.

Q: What determines substitution eligibility between these resistors?

A: Substitution is based on matching resistance value, tolerance, composition, temperature coefficient, operating temperature range, package type, and compliance certifications. The RNMF14FTC6K80 meets all these criteria while providing enhanced power rating capability.
