RMCF0805FG511K Equivalent & Substitute Parts

Part Overview

The RMCF0805FG511K is a 511 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This automotive-grade component meets AEC-Q200 specifications and operates across -55°C to 155°C. Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when alternative manufacturers' components are preferred for procurement flexibility while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (511 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99). All listed substitute parts meet these criteria. Physical dimensions and height variations within the 0805 package specification do not affect electrical performance or PCB assembly compatibility. Packaging format (Tape & Reel or Cut Tape) represents a procurement variable only and does not impact functional substitution.

Engineering Selection Recommendations

RMCF0805FT511K (Stackpole Electronics Inc) provides direct manufacturer continuity with identical specifications and active product status. CRCW0805511KFKEA (Vishay Dale), ERJ-6ENF5113V (Panasonic Electronic Components), CR0805-FX-5113ELF (Bourns Inc.), and RC0805FR-07511KL (YAGEO) are all active products with full compliance certifications (ROHS3, REACH Unaffected, EAR99). MCR10ERTF5113 (Rohm Semiconductor) is discontinued at DiGi Electronics and should be avoided for new designs requiring long-term availability. All active substitutes maintain identical electrical performance and 0805 package compatibility. Selection should prioritize active product status and supplier availability for procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FG511K be replaced with CRCW0805511KFKEA? A: Yes. Both components share identical resistance (511 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 0805 package specification. Physical height variation (0.020" vs 0.026") remains within 0805 package tolerances and does not affect PCB assembly or electrical performance.

Q: What is the difference between RMCF0805FG511K and RMCF0805FT511K? A: Both are Stackpole Electronics Inc products with identical electrical specifications and active status. The difference lies in internal manufacturing parameters (indicated by the FG vs FT designation) that do not affect functional performance or substitution eligibility.

Q: Why is MCR10ERTF5113 listed if it is discontinued? A: MCR10ERTF5113 meets all electrical and mechanical substitution criteria but is discontinued at DiGi Electronics. It is included for reference in legacy designs or when existing inventory is available from alternative sources. New designs should select from active products.

Q: Are automotive AEC-Q200 specifications maintained across all substitutes? A: RMCF0805FG511K, RMCF0805FT511K, CRCW0805511KFKEA, and ERJ-6ENF5113V explicitly list AEC-Q200 compliance. CR0805-FX-5113ELF and RC0805FR-07511KL do not specify AEC-Q200 but maintain equivalent electrical and thermal performance. MCR10ERTF5113 does not list automotive ratings. For automotive applications requiring AEC-Q200 certification, select from the first four options.

Q: Does packaging format (Tape & Reel vs Cut Tape) affect substitution? A: Packaging format is a procurement and handling variable only. Tape & Reel and Cut Tape formats contain identical components and do not affect electrical performance or PCB assembly compatibility. Selection should be based on manufacturing equipment and inventory management requirements.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. All substitute parts maintain the -55°C to 155°C operating temperature range and ±100ppm/°C temperature coefficient. Electrical performance remains stable across this range for all listed components.
