RMCF0805FT866K Equivalent & Substitute Parts

Part Overview

The RMCF0805FT866K is a 866 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently active in production. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility across multiple qualified suppliers is required for production resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RMCF0805FT866K is determined by strict equivalence across the following parameters: resistance value (866 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 substitute parts listed maintain identical electrical specifications and mechanical compatibility. Physical dimensions (length, width, and seated height) may vary within acceptable tolerances for PCB assembly. Automotive AEC-Q200 qualification is present in the primary part and two direct substitutes; one substitute (MCR10ERTF8663) does not specify AEC-Q200 features. One substitute (RC0805FR-07866KL) includes moisture-resistant construction as an additional feature. All parts are packaged in Tape & Reel format and are RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, CRCW0805866KFKEA (Vishay Dale) and ERJ-6ENF8663V (Panasonic Electronic Components) are direct equivalents with active product status and full automotive compliance. CRCW0805866KFKEA offers the highest inventory availability at 17,299 units. ERJ-6ENF8663V provides an alternative with 7,413 units in stock.

RC0805FR-07866KL (YAGEO) is suitable for applications where automotive AEC-Q200 qualification is not required. This part features moisture-resistant construction and maintains all core electrical parameters. YAGEO RC0805FR-07866KL has the largest inventory position at 64,787 units, providing maximum supply availability.

MCR10ERTF8663 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs or production orders requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805866KFKEA replace RMCF0805FT866K in automotive applications? A: Yes. Both parts share identical electrical specifications (866 kOhms ±1%, 0.125W), operate across -55°C to 155°C, and carry AEC-Q200 automotive qualification. The 0805 package is mechanically compatible. Physical height differences (0.020" vs 0.026") are within PCB assembly tolerances.

Q: Is RC0805FR-07866KL suitable for automotive designs? A: RC0805FR-07866KL does not carry AEC-Q200 automotive qualification. It is suitable for non-automotive applications requiring the specified electrical parameters and moisture-resistant construction. For automotive applications, use CRCW0805866KFKEA or ERJ-6ENF8663V.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 parts? A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. Parts with AEC-Q200 rating (RMCF0805FT866K, CRCW0805866KFKEA, ERJ-6ENF8663V) are qualified for automotive use. Non-qualified parts lack this certification and should not be used in automotive designs without engineering review.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed parts, including the primary RMCF0805FT866K and all substitutes, are ROHS3 compliant and REACH unaffected.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry MSL 1 rating.

Q: Can I use ERJ-6ENF8663V and CRCW0805866KFKEA interchangeably? A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, and operating temperature range. Both carry AEC-Q200 qualification. Minor physical height variations (0.028" vs 0.020") are within standard PCB assembly tolerances.

Q: Why is MCR10ERTF8663 listed if it is discontinued? A: MCR10ERTF8663 is included for reference purposes only. It is discontinued at DiGi Electronics and should not be selected for new designs or production. Use active alternatives: CRCW0805866KFKEA, ERJ-6ENF8663V, or RC0805FR-07866KL.
