RMCF0201FT178R Equivalent & Substitute Parts

Part Overview

The RMCF0201FT178R is a 178 Ohm ±1% thick film chip resistor manufactured by Stackpole Electronics Inc in the 0201 (0603 Metric) package format. This component is rated for 0.05W (1/20W) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and carries ROHS3 compliance with AEC-Q200 qualification. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF0201FT178R is determined by strict alignment of the following parameters: resistance value (178 Ohms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), and compliance certifications (ROHS3). All identified substitute parts match these core electrical and mechanical specifications. Operating temperature range variations and minor dimensional differences in seated height do not preclude substitution when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original RMCF0201FT178R. The CRCW0201178RFNED and RMCF0201FT178R share identical operating temperature ranges (-55°C to 155°C), providing direct thermal compatibility. The ERJ-1GNF1780C and RC0201FR-07178RL operate to 125°C maximum, which represents a reduced upper temperature limit suitable for applications not requiring the full 155°C capability. The RC0201FR-07178RL includes moisture-resistant composition as an additional feature. All parts carry MSL 1 (Unlimited) rating and are available in Tape & Reel packaging format.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the RMCF0201FT178R? A: Substitution requires matching resistance value (178 Ohms), tolerance (±1%), power rating (0.05W), package format (0201), thick film composition, temperature coefficient (±200ppm/°C), and ROHS3 compliance. Operating temperature range and seated height variations do not prevent substitution when all primary parameters align.

Q: Can ERJ-1GNF1780C and RC0201FR-07178RL be used in applications requiring 155°C operation? A: No. These parts are rated to 125°C maximum operating temperature. Applications requiring operation above 125°C must use RMCF0201FT178R or CRCW0201178RFNED, both rated to 155°C.

Q: Are all substitute parts available in the same packaging format? A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the original component format.

Q: What is the significance of the moisture-resistant feature on the RC0201FR-07178RL? A: The RC0201FR-07178RL includes moisture-resistant thick film composition. All parts carry MSL 1 (Unlimited) rating. The moisture-resistant feature provides additional protection in high-humidity environments but does not affect substitution eligibility based on core electrical parameters.

Q: Do seated height differences affect PCB assembly compatibility? A: The RMCF0201FT178R has a maximum seated height of 0.011" (0.28mm), while substitute parts measure 0.010" (0.26mm). This 0.001" difference is within standard PCB assembly tolerances and does not affect placement or soldering processes for 0201 package components.
