RC0603J202CS Equivalent & Substitute Parts Reference

Part Overview

The RC0603J202CS is a 2 kOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0201 (0603 Metric) package format with 0.05W power rating. This component is classified as Active product status with 625 pieces currently in stock. The part is designed for moisture-resistant applications with unlimited moisture sensitivity level (MSL 1) and operates across the temperature range of -55°C to 125°C.

Equivalent and substitute parts are necessary when the original manufacturer part becomes unavailable, when design requirements demand improved tolerance specifications, or when supply chain optimization requires alternative sourcing from qualified manufacturers. Substitute parts must maintain electrical compatibility through matching resistance value, power rating, and package dimensions while accommodating tolerance and temperature coefficient variations within acceptable design margins.

• Package / Case: 0201 (0603 Metric) (physical compatibility requirement)
• Power Rating: 0.05W minimum (1/20W)
• Composition: Thick Film (performance consistency)
• Number of Terminations: 2 (standard configuration)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Allowable Variation Parameters:

• Tolerance: ±5% (original specification) or ±1% (improved specification acceptable as upgrade)
• Operating Temperature Range: -55°C to 125°C (minimum) or -55°C to 155°C (extended range acceptable)
• Temperature Coefficient: ±250ppm/°C (original) or ±100ppm/°C (improved specification acceptable)
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® (format variation acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) (must maintain or improve)

Product Status Consideration: Substitute parts may be Active or Discontinued at DiGi Electronics, provided all electrical and mechanical parameters remain compatible with the original specification.

Engineering Selection Recommendations

CRCW02012K00FKED (Vishay Dale) - Upgrade Substitute:

The CRCW02012K00FKED is classified as an upgrade substitute due to improved tolerance specification (±1% versus ±5%) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). This part maintains all critical electrical and mechanical parameters including 2 kOhms resistance, 0.05W power rating, 0201 package format, and thick film composition. The temperature coefficient is improved to ±100ppm/°C. Product status is Active with 57461 pieces in stock. RoHS3 compliance and MSL 1 rating are maintained. This substitute is suitable for applications requiring higher accuracy and extended thermal operating range.

MCR006YRTF2001 (Rohm Semiconductor) - Similar Substitute:

The MCR006YRTF2001 provides electrical equivalence with improved tolerance (±1%) and matching temperature coefficient (±250ppm/°C) to the original part. All critical parameters align: 2 kOhms resistance, 0.05W power rating, 0201 package, and thick film composition. Operating temperature range matches the original specification (-55°C to 125°C). Product status is Discontinued at DiGi Electronics with 678 pieces in stock. RoHS3 compliance and MSL 1 rating are maintained. This substitute is suitable for direct replacement in applications where tolerance improvement is beneficial and discontinued status is acceptable.

MCR006YRTJ202 (Rohm Semiconductor) - Similar Substitute:

The MCR006YRTJ202 provides direct electrical equivalence with matching tolerance (±5%) and temperature coefficient (±250ppm/°C) to the original RC0603J202CS. All critical parameters are identical: 2 kOhms resistance, 0.05W power rating, 0201 package, and thick film composition. Operating temperature range matches (-55°C to 125°C). Product status is Discontinued at DiGi Electronics with 8774 pieces in stock. RoHS3 compliance and MSL 1 rating are maintained. This substitute is suitable for direct replacement in applications requiring identical electrical specifications.

Frequently Asked Questions (FAQ)

Q1: Can CRCW02012K00FKED replace RC0603J202CS in all applications?

A: CRCW02012K00FKED is electrically and mechanically compatible with RC0603J202CS. The improved tolerance (±1% versus ±5%) and extended temperature range (-55°C to 155°C) make it suitable for applications where the original part is specified. The ±1% tolerance is tighter than the original ±5%, which may affect circuit tuning or calibration procedures designed around the original tolerance band. Verify circuit design requirements before substitution.

Q2: What is the difference between the two Rohm Semiconductor parts (MCR006YRTF2001 and MCR006YRTJ202)?

A: Both parts are manufactured by Rohm Semiconductor in 0201 package with 2 kOhms resistance and 0.05W power rating. The primary difference is tolerance specification: MCR006YRTF2001 has ±1% tolerance while MCR006YRTJ202 has ±5% tolerance matching the original RC0603J202CS. Both parts are discontinued at DiGi Electronics but maintain adequate inventory. Selection depends on tolerance requirements for the specific application.

Q3: Are packaging format differences between Tape & Reel and Cut Tape significant for substitution?

A: Packaging format differences (Tape & Reel versus Cut Tape or Digi-Reel®) do not affect electrical or mechanical compatibility. Format selection is determined by assembly process requirements and handling procedures. All substitute parts maintain identical physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and height (0.010" maximum, 0.26mm), ensuring PCB footprint compatibility regardless of packaging format.

Q4: Why does CRCW02012K00FKED have a lower temperature coefficient (±100ppm/°C) compared to the original (±250ppm/°C)?

A: Temperature coefficient specification indicates the rate of resistance change per degree Celsius. The lower temperature coefficient (±100ppm/°C) in CRCW02012K00FKED represents improved stability across temperature variations. This is a performance enhancement, not a limitation. Applications sensitive to temperature-induced resistance drift benefit from the improved specification.

Q5: Can discontinued parts be used as substitutes in new designs?

A: Discontinued parts (MCR006YRTF2001 and MCR006YRTJ202) maintain full electrical and mechanical compatibility with the original RC0603J202CS. However, discontinued status indicates limited future availability. For new designs, Active status parts (RC0603J202CS or CRCW02012K00FKED) are recommended to ensure long-term supply chain stability. Discontinued parts are suitable for legacy system maintenance or short-term production runs where current inventory is sufficient.

Q6: What does RoHS3 compliance mean for component substitution?

A: RoHS3 compliance indicates the component meets Restriction of Hazardous Substances directive requirements, restricting lead and other hazardous materials. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory compatibility for applications subject to RoHS requirements. This compliance status is maintained across all substitute options.

Q7: Is MSL 1 (Unlimited) rating the same across all substitute parts?

A: Yes, all substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level rating, identical to the original RC0603J202CS. This rating indicates the component does not require special moisture control during storage or handling, simplifying logistics and assembly procedures. No additional moisture barrier packaging or baking procedures are required for any of the listed substitutes.
