Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4640CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (464 Ohms), tolerance (±1%), and power rating (0.125W / 1/8W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 1.25mm W), and number of terminations (2) ensure physical and electrical compatibility with printed circuit board layouts and assembly processes.

Material & Composition: All substitute parts utilize thick film construction, maintaining consistent electrical behavior and reliability characteristics.

Compliance & Environmental: ROHS3 compliance and MSL 1 rating are maintained across all qualified substitutes. Operating temperature range remains constant at -55°C ~ 155°C.

The four identified substitute parts (CRCW0805464RFKEA, ERJ-6ENF4640V, RC0805FR-07464RL, RMCF0805FT464R) meet all these criteria and are therefore electrically and mechanically interchangeable with the RCS2012F4640CS.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are qualified equivalents to the RCS2012F4640CS based on matching electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

Automotive Applications: The CRCW0805464RFKEA (Vishay Dale), ERJ-6ENF4640V (Panasonic), and RMCF0805FT464R (Stackpole) carry AEC-Q200 automotive qualification ratings. These parts are suitable for automotive and high-reliability applications requiring automotive-grade component certification.

General Industrial Applications: The RC0805FR-07464RL (YAGEO) is qualified for general industrial use with moisture-resistant construction and does not carry automotive certification.

Availability & Supply Chain: Inventory levels vary across manufacturers. ERJ-6ENF4640V (Panasonic) offers the highest inventory availability at 117,693 pieces. CRCW0805464RFKEA (Vishay Dale) provides 8,078 pieces, RC0805FR-07464RL (YAGEO) provides 44,580 pieces, and RMCF0805FT464R (Stackpole) provides 3,989 pieces.

Physical Height Variation: Seated height specifications range from 0.020" (0.50mm) to 0.028" (0.70mm). In applications with strict height constraints or high-density PCB layouts, the CRCW0805464RFKEA offers the lowest profile at 0.020" maximum seated height.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature range (-55°C ~ 155°C), ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS2012F4640CS with any of these four parts without circuit redesign?

A: Yes. All four substitute parts (CRCW0805464RFKEA, ERJ-6ENF4640V, RC0805FR-07464RL, RMCF0805FT464R) are electrically and mechanically equivalent. They share identical resistance value (464 Ohms), tolerance (±1%), power rating (0.125W), package type (0805), and operating temperature range (-55°C ~ 155°C). No circuit redesign is required for direct substitution.

Q: What is the difference between the main part and the substitutes?

A: The primary differences are manufacturer identity and optional automotive certification. The RCS2012F4640CS (Samsung) features anti-sulfur construction. Three substitutes (Vishay Dale, Panasonic, Stackpole) carry AEC-Q200 automotive qualification, while the YAGEO part does not. Physical height varies slightly (0.020" to 0.028" maximum seated height) but remains within standard 0805 package specifications.

Q: Are these parts suitable for automotive applications?

A: Three of the four substitutes carry AEC-Q200 automotive qualification: CRCW0805464RFKEA (Vishay Dale), ERJ-6ENF4640V (Panasonic), and RMCF0805FT464R (Stackpole). The RC0805FR-07464RL (YAGEO) does not carry automotive certification and is suitable for general industrial applications. The original RCS2012F4640CS does not carry automotive certification.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. All five parts (main part and four substitutes) are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), meeting environmental and regulatory requirements for industrial and consumer electronics applications.

Q: What is the temperature coefficient specification, and is it identical across all parts?

A: The temperature coefficient is ±100ppm/°C for all parts, including the main RCS2012F4640CS and all four substitutes. This specification defines the resistance change per degree Celsius across the operating temperature range of -55°C ~ 155°C.

Q: Are there any physical dimension differences that could affect PCB assembly?

A: All parts conform to the 0805 (2012 Metric) package standard with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Seated height varies from 0.020" to 0.028" maximum. In high-density layouts or applications with strict height constraints, the CRCW0805464RFKEA (0.020" maximum height) offers the lowest profile option.

Q: Which substitute part offers the best availability?

A: ERJ-6ENF4640V (Panasonic) provides the highest inventory availability at 117,693 pieces in stock. RC0805FR-07464RL (YAGEO) offers 44,580 pieces, CRCW0805464RFKEA (Vishay Dale) offers 8,078 pieces, and RMCF0805FT464R (Stackpole) offers 3,989 pieces.

Q: Can I mix these parts in the same production batch?

A: Yes. All parts are electrically and mechanically equivalent and can be used interchangeably in the same circuit design and PCB layout. However, manufacturing and quality documentation should reflect the specific part number used in each production batch for traceability and compliance purposes.
