Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical equivalence to the RNF14FTC110R across critical parameters: 110 Ohms resistance, ±1% tolerance, metal film composition, and ±50ppm/°C temperature coefficient. All parts are active products with ROHS3 compliance.

RNMF14FTC110R (Stackpole Electronics Inc): Direct electrical equivalent with identical power rating and operating temperature range. Differs in physical dimensions (smaller form factor) and packaging format (Cut Tape vs. Tape & Reel). Suitable for applications where space constraints favor compact dimensions.

CMF50110R00FHEB (Vishay Dale): Direct electrical equivalent with identical power rating and tolerance. Extended operating temperature range (-55°C ~ 175°C) provides enhanced thermal performance. Smallest physical dimensions among substitutes. Packaging format is Cut Tape.

CMF55110R00FHEB (Vishay Dale): Electrical equivalent with elevated power rating (0.5W vs. 0.25W) and extended operating temperature range (-55°C ~ 175°C). Suitable for applications requiring higher power dissipation capability or enhanced thermal margin. Packaging format is Cut Tape.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC110R replace RNF14FTC110R in my circuit?

A: Yes. RNMF14FTC110R is electrically equivalent with identical resistance, tolerance, power rating, and temperature coefficient. The primary difference is physical size (smaller) and packaging format (Cut Tape instead of Tape & Reel). Verify that the smaller dimensions do not conflict with PCB layout constraints.

Q: What is the difference between CMF50110R00FHEB and CMF55110R00FHEB?

A: Both are Vishay Dale metal film resistors with 110 Ohms ±1% specification. CMF50110R00FHEB has 0.25W power rating, while CMF55110R00FHEB has 0.5W power rating. CMF55110R00FHEB provides higher power dissipation capability and is suitable for applications requiring greater thermal headroom.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RNF14FTC110R and all listed substitutes (RNMF14FTC110R, CMF50110R00FHEB, CMF55110R00FHEB) are ROHS3 compliant.

Q: Can I use CMF55110R00FHEB (0.5W) in place of RNF14FTC110R (0.25W)?

A: Yes. The 0.5W rated resistor is electrically compatible and provides equivalent or superior performance in all electrical parameters. The higher power rating does not create incompatibility; it provides additional thermal margin.

Q: What are the physical dimension differences between substitutes?

A: RNF14FTC110R measures 0.093" Dia x 0.250" L. RNMF14FTC110R is the smallest at 0.070" Dia x 0.130" L. CMF50110R00FHEB measures 0.065" Dia x 0.150" L. CMF55110R00FHEB measures 0.090" Dia x 0.240" L. Verify PCB layout compatibility before selection.

Q: What packaging formats are available?

A: RNF14FTC110R is supplied in Tape & Reel (TR) format. RNMF14FTC110R, CMF50110R00FHEB, and CMF55110R00FHEB are supplied in Cut Tape (CT) format. Both formats are suitable for automated assembly; verify compatibility with your procurement and assembly processes.

Q: Do all substitutes have the same operating temperature range?

A: No. RNF14FTC110R and RNMF14FTC110R operate from -55°C to 155°C. CMF50110R00FHEB and CMF55110R00FHEB extend to -55°C to 175°C, providing enhanced high-temperature performance.
