Substitute Part Grouping Explanation

Substitute parts for the RMCF0201FT18R2 are qualified based on the following criteria:

Electrical Parameters: Resistance value of 18.2 Ohms with ±1% tolerance, power rating of 0.05W (1/20W), and temperature coefficient of ±200ppm/°C must match exactly.

Mechanical Parameters: Package designation of 0201 (0603 Metric) with identical footprint dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and two terminations.

Environmental & Compliance: RoHS3 compliance, MSL rating of 1 (Unlimited), REACH unaffected status, and EAR99 ECCN classification must be maintained.

Composition: Thick film construction is required for all substitutes.

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the RMCF0201FT18R2 in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW020118R2FNED be used as a direct replacement for RMCF0201FT18R2?

A: Yes. Both parts share identical resistance (18.2 Ohms ±1%), power rating (0.05W), package dimensions (0201 / 0603 Metric), and operating temperature range (-55°C ~ 155°C). Electrical and mechanical interchangeability is confirmed.

Q: What is the difference between ERJ-1GNF18R2C and RC0201FR-0718R2L?

A: Both parts are electrically equivalent with 18.2 Ohms ±1% resistance and 0.05W power rating in 0201 package. The primary difference is that RC0201FR-0718L features moisture-resistant thick film construction. Both have operating temperature ranges of -55°C ~ 125°C, which is 30°C lower than the RMCF0201FT18R2 maximum rating.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Does the 0.001" difference in seated height between RMCF0201FT18R2 and substitute parts affect circuit board assembly?

A: No. The RMCF0201FT18R2 has a maximum seated height of 0.011" (0.28mm), while substitute parts measure 0.010" (0.26mm). This 0.001" variation is within standard PCB assembly tolerances and does not impact component placement or solder joint integrity.

Q: Can these parts be used interchangeably in high-temperature applications?

A: CRCW020118R2FNED and RMCF0201FT18R2 both support -55°C ~ 155°C operation and are suitable for extended temperature applications. ERJ-1GNF18R2C and RC0201FR-0718R2L are rated to -55°C ~ 125°C and should be evaluated against specific application temperature requirements.
