Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC0603J682CS is based on the following critical parameters that must remain constant or improve:

Mandatory Compatibility Parameters:

• Resistance value: 6.8 kOhms (exact match required)
• Power rating: 0.05W minimum (1/20W)
• Package / Case: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W maximum
• Number of terminations: 2 (exact match required)
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited) or equivalent

Parameters Allowed to Improve:

• Tolerance: ±5% (main part) can be substituted with ±1% (tighter tolerance)
• Temperature coefficient: ±250ppm/°C can be substituted with ±100ppm/°C (lower coefficient)
• Operating temperature range: -55°C ~ 125°C can be extended to -55°C ~ 155°C

Parameters Allowed to Vary:

• Packaging format: Tape & Reel (TR) or Cut Tape (CT) are interchangeable for component selection
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters align

Substitute parts are classified as:

• Upgrade: Improved tolerance (±1%) with same or better temperature performance
• Similar: Equivalent specifications with potential product status or availability considerations

Parameter Comparison

Engineering Selection Recommendations

RC0603F682CS (Samsung Electro-Mechanics)

This upgrade substitute provides improved tolerance specification (±1% versus ±5%) while maintaining identical electrical and mechanical characteristics. Both parts are manufactured by Samsung Electro-Mechanics within the same RC series, ensuring design consistency. The RC0603F682CS is supplied in Cut Tape (CT) format with higher inventory availability (2307 pieces). Product status is Active with full RoHS3 compliance and MSL 1 rating. Selection of this part is appropriate when tighter tolerance requirements are specified in circuit design without operational temperature extension needs.

CRCW02016K80FKED (Vishay Dale)

This upgrade substitute offers the most extended operating temperature range (-55°C ~ 155°C) and lowest temperature coefficient (±100ppm/°C) among all alternatives. The CRCW02016K80FKED maintains ±1% tolerance with identical package dimensions and power rating. Manufactured by Vishay Dale within the CRCW series, this part is supplied in Tape & Reel (TR) format with the highest inventory availability (27223 pieces). Product status is Active with full RoHS3 compliance and MSL 1 rating. Selection of this part is appropriate for applications requiring extended temperature performance or superior temperature stability.

MCR006YRTF6801 (Rohm Semiconductor)

This similar substitute provides ±1% tolerance with identical operating temperature range and temperature coefficient as the main part. Manufactured by Rohm Semiconductor within the MCR series, this part is supplied in Cut Tape (CT) & Digi-Reel® format with moderate inventory availability (5239 pieces). Product status is Discontinued at DiGi Electronics, indicating limited future availability. This part is suitable for applications where tolerance improvement is required but extended temperature performance is not necessary, with the understanding that long-term procurement may become constrained.

Frequently Asked Questions (FAQ)

Q: Can RC0603F682CS be used as a direct replacement for RC0603J682CS?

A: Yes. The RC0603F682CS is a direct electrical and mechanical substitute with improved tolerance specification (±1% versus ±5%). Both parts share identical resistance value (6.8 kOhms), power rating (0.05W), package dimensions (0201 / 0603 Metric), and operating temperature range (-55°C ~ 125°C). The primary difference is packaging format (Cut Tape versus Tape & Reel), which does not affect component functionality.

Q: What is the advantage of CRCW02016K80FKED over RC0603J682CS?

A: The CRCW02016K80FKED provides three performance improvements: (1) tighter tolerance specification (±1% versus ±5%), (2) extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C), and (3) lower temperature coefficient (±100ppm/°C versus ±250ppm/°C). These improvements result in superior temperature stability and wider operational envelope. The trade-off is manufacturer change from Samsung Electro-Mechanics to Vishay Dale.

Q: Is MCR006YRTF6801 still available for new designs?

A: MCR006YRTF6801 is currently discontinued at DiGi Electronics, indicating limited future procurement availability. While 5239 pieces remain in stock, this part should not be selected for new designs requiring long-term component supply. RC0603F682CS or CRCW02016K80FKED are recommended alternatives for ongoing production requirements.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect component selection?

A: Packaging format does not affect electrical or mechanical performance. Tape & Reel (TR) format is optimized for automated assembly processes with high-volume production. Cut Tape (CT) format is suitable for lower-volume applications or manual assembly. Selection between formats depends on manufacturing process requirements, not component functionality.

Q: Can these substitutes be used interchangeably in existing PCB designs?

A: Yes, all substitute parts maintain identical package dimensions (0201 / 0603 Metric), footprint, and pin configuration. PCB layout and component placement require no modification. Electrical performance differences (tolerance and temperature coefficient) do not affect PCB physical compatibility.

Q: What is the significance of RoHS3 compliance and MSL 1 rating?

A: RoHS3 compliance indicates the part meets European Union Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. MSL 1 (Unlimited) rating indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All substitute parts maintain these compliance certifications, ensuring regulatory and environmental compatibility.

Q: Which substitute part should be selected for high-temperature applications?

A: CRCW02016K80FKED is the appropriate selection for applications requiring extended temperature performance. This part operates across -55°C ~ 155°C (30°C extended upper limit) with the lowest temperature coefficient (±100ppm/°C) among all alternatives, providing superior stability across the full operating range.
