Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC0603F683CS are qualified based on the following critical parameters:

Electrical Equivalence: Resistance value of 68 kOhms, tolerance of ±1%, and power rating of 0.05W (1/20W) are mandatory matching criteria.

Mechanical Compatibility: Package type 0201 (0603 Metric), physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm), and maximum seated height of 0.010" (0.26mm) ensure direct board-level compatibility.

Composition & Construction: Thick film construction maintains functional equivalence in circuit performance.

Compliance & Certification: ROHS3 compliance and MSL 1 rating are required for environmental and handling compatibility.

Temperature Performance: Operating temperature range must support the application's thermal requirements.

Substitutes are categorized as Direct or Similar based on alignment with these parameters. Direct substitutes maintain identical or superior specifications across all critical dimensions. Similar substitutes meet core electrical and mechanical requirements but may differ in secondary parameters such as temperature coefficient or packaging format.

Engineering Selection Recommendations

CRCW020168K0FKED (Vishay Dale) - Direct Substitute

This component qualifies as a direct substitute. All electrical specifications (68 kOhms, ±1%, 0.05W) and mechanical dimensions match the RC0603F683CS. The Vishay part offers an extended operating temperature range (-55°C to 155°C) and superior temperature coefficient (±100ppm/°C), providing enhanced performance margin. ROHS3 compliance and MSL 1 rating ensure regulatory and handling compatibility. Active product status supports long-term availability. Tape & Reel packaging is suitable for high-volume production environments.

MCR006YRTF6802 (Rohm Semiconductor) - Similar Substitute

This component meets core electrical and mechanical requirements with identical resistance, tolerance, power rating, and package dimensions. Temperature coefficient (±250ppm/°C) and operating range (-55°C to 125°C) match the original Samsung part. ROHS3 compliance and MSL 1 rating are equivalent. However, this part is classified as Discontinued at DiGi Electronics, which may impact long-term supply chain reliability. Use is appropriate for applications where existing inventory is available or where alternative sourcing channels are established.

Frequently Asked Questions (FAQ)

Q: Can CRCW020168K0FKED replace RC0603F683CS in all applications?

A: Yes. Both components share identical electrical specifications (68 kOhms ±1%, 0.05W), mechanical dimensions (0201 package, 0.024" x 0.012"), and compliance certifications (ROHS3, MSL 1). The Vishay part's extended temperature range and lower temperature coefficient provide equivalent or superior performance.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging is supplied in individual strips suitable for manual assembly or small-batch operations. Tape & Reel (TR) packaging is wound on reels for automated pick-and-place assembly in high-volume production. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Why is MCR006YRTF6802 marked as Discontinued?

A: Discontinued at DiGi Electronics indicates this part number is no longer actively stocked by that distributor. However, the component may remain available through alternative suppliers or existing inventory channels. Verify availability through your supply chain before design selection.

Q: Are all three parts interchangeable at the board level?

A: Yes. All three components conform to the 0201 (0603 Metric) package standard with identical physical dimensions (0.024" L x 0.012" W, 0.010" max height). Direct substitution on PCBs is mechanically and electrically compatible.

Q: What does MSL 1 (Unlimited) mean for handling?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. No baking or desiccant storage is required before assembly.

Q: How do temperature coefficients affect circuit performance?

A: Temperature coefficient (ppm/°C) specifies resistance change per degree Celsius. The Samsung and Rohm parts (±250ppm/°C) and Vishay part (±100ppm/°C) all operate within acceptable tolerance bands for standard applications. Selection depends on circuit sensitivity to resistance drift across the operating temperature range.
