Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F4640CS is determined by strict equivalence across the following critical parameters:

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

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and number of terminations (2) ensure physical and electrical interface compatibility. Seated height variations within the 0.020" to 0.028" range do not affect circuit board assembly or performance.

Environmental & Compliance Requirements: All substitute parts maintain RoHS3 compliance, Moisture Sensitivity Level 1, and REACH Unaffected status. Composition (Thick Film) and moisture resistance features are preserved across all qualified substitutes.

Packaging Format: Tape & Reel (TR) packaging is the primary delivery method for all listed substitutes, ensuring compatibility with automated assembly processes.

The four identified substitute parts (RC0805FR-07464RL, CRCW0805464RFKEA, ERJ-6ENF4640V, RMCF0805FT464R) meet all electrical and mechanical parameters. Two substitutes (CRCW0805464RFKEA, ERJ-6ENF4640V, RMCF0805FT464R) include Automotive AEC-Q200 qualification, providing additional reliability certification for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are qualified for direct replacement of the RC2012F4640CS based on identical electrical and mechanical specifications. Selection among substitutes should be based on the following factors:

General-Purpose Applications: RC0805FR-07464RL (YAGEO) offers the lowest seated height (0.024" / 0.60mm) and represents a direct functional equivalent without additional automotive qualification. This part is suitable for standard consumer and industrial applications.

Automotive Applications: CRCW0805464RFKEA (Vishay Dale), ERJ-6ENF4640V (Panasonic), and RMCF0805FT464R (Stackpole) all carry Automotive AEC-Q200 qualification. These parts are specified for automotive-grade reliability requirements and should be selected when designs require AEC-Q200 certification. ERJ-6ENF4640V provides the highest inventory availability (117,693 pcs) among automotive-qualified options.

Compliance Verification: All substitute parts maintain RoHS3 compliance and REACH Unaffected status, matching the environmental and regulatory requirements of the original part. Moisture Sensitivity Level 1 (Unlimited) is consistent across all options, eliminating moisture-related handling constraints.

Product Continuity: All parts maintain Active product status, ensuring long-term availability and supply chain stability for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07464RL be used as a direct replacement for RC2012F4640CS in all applications?

A: Yes. RC0805FR-07464RL matches all critical electrical parameters (464 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical specifications (0805 package, 2 terminations). The 0.002" (0.06mm) difference in seated height is within acceptable circuit board assembly tolerances and does not affect performance or compatibility.

Q: What is the difference between the standard RC0805FR-07464RL and the automotive-qualified alternatives?

A: CRCW0805464RFKEA, ERJ-6ENF4640V, and RMCF0805FT464R include Automotive AEC-Q200 qualification, indicating compliance with automotive industry reliability and testing standards. Electrical and mechanical specifications remain identical. Standard applications do not require AEC-Q200 qualification; automotive designs should specify AEC-Q200 qualified parts.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All four substitute parts are supplied in Tape & Reel (TR) format, compatible with automated surface-mount assembly equipment. CRCW0805464RFKEA is also available in Cut Tape (CT) & Digi-Reel® format as an alternative packaging option.

Q: Do seated height variations affect circuit board design or assembly?

A: No. Seated height variations range from 0.020" to 0.028" (0.50mm to 0.70mm) across all parts. These variations fall within standard PCB assembly tolerances and do not require design modifications. Component placement and reflow profiles remain unchanged.

Q: Which substitute part offers the best inventory availability?

A: ERJ-6ENF4640V (Panasonic) provides the highest inventory level at 117,693 pcs. RC0805FR-07464RL (YAGEO) offers 44,580 pcs. Both parts ensure supply continuity for high-volume production requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts carry RoHS3 compliance certification and REACH Unaffected status, matching the environmental requirements of the original RC2012F4640CS.
