RC0603F112CS Equivalent & Substitute Parts Reference

Part Overview

The RC0603F112CS is a 1.1 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics. This 0201 (0603 Metric) surface mount resistor is rated for 0.05W (1/20W) power dissipation and operates across the temperature range of -55°C to 125°C. The component features moisture-resistant construction with unlimited moisture sensitivity level (MSL 1) and maintains ROHS3 compliance.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size, termination count), and environmental operating parameters. Alternative sources become necessary when the primary part experiences inventory constraints, extended lead times, or when design flexibility permits component sourcing from multiple qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following parameters:

Mandatory Matching Criteria:

• Resistance value: 1.1 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Allowable Variation:

• Operating temperature range: Substitute parts may extend the upper or lower temperature limit beyond the main part specification without affecting substitution validity
• Temperature coefficient: Variation permitted within industry-standard ranges for thick film resistors
• Packaging format: Cut Tape (CT), Tape & Reel (TR), and Digi-Reel® formats are interchangeable for equivalent parts

Identified Substitutes:

1. CRCW02011K10FKED (Vishay Dale) – Direct equivalent with extended upper operating temperature (155°C vs. 125°C) and improved temperature coefficient (±100ppm/°C vs. ±250ppm/°C)

2. MCR006YRTF1101 (Rohm Semiconductor) – Functional equivalent with identical operating temperature range and temperature coefficient; product status is discontinued at DiGi Electronics

Engineering Selection Recommendations

CRCW02011K10FKED (Vishay Dale) – Preferred Substitute

This part is the recommended primary substitute for RC0603F112CS. It maintains full electrical and mechanical compatibility while offering superior performance characteristics. The extended operating temperature range to 155°C provides additional thermal margin for applications requiring higher ambient or component-level temperatures. The improved temperature coefficient of ±100ppm/°C (versus ±250ppm/°C) delivers enhanced frequency stability and reduced drift over the operating temperature range. The part is actively manufactured and widely available in Tape & Reel packaging format. ROHS3 compliance and MSL 1 rating ensure regulatory and handling compatibility with the original specification.

MCR006YRTF1101 (Rohm Semiconductor) – Secondary Substitute

This part provides functional equivalence with identical electrical specifications and operating temperature range. However, the product status is listed as discontinued at DiGi Electronics, which may limit long-term availability and future procurement. The temperature coefficient matches the original part at ±250ppm/°C. This substitute is suitable for applications where inventory exists or where alternative distribution channels provide reliable supply. ROHS3 compliance and MSL 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can CRCW02011K10FKED be used as a direct replacement for RC0603F112CS in all applications?

A: Yes. Both parts meet the mandatory electrical specifications (1.1 kOhms ±1%, 0.05W), occupy identical physical footprints (0201 package), and maintain equivalent regulatory compliance (ROHS3, MSL 1). The CRCW02011K10FKED offers extended temperature range capability, making it suitable for all applications where RC0603F112CS is specified.

Q: What is the significance of the temperature coefficient difference between RC0603F112CS (±250ppm/°C) and CRCW02011K10FKED (±100ppm/°C)?

A: Temperature coefficient defines the rate of resistance change per degree Celsius. The lower coefficient of CRCW02011K10FKED (±100ppm/°C) indicates superior frequency stability and reduced resistance drift across temperature variations. For precision analog circuits, timing networks, or applications with wide temperature operation, the improved coefficient provides better performance. For general-purpose digital applications, both coefficients are acceptable.

Q: Are packaging format differences (Cut Tape vs. Tape & Reel) significant for substitution?

A: Packaging format differences do not affect electrical or mechanical compatibility. Cut Tape (CT) and Tape & Reel (TR) formats contain identical components with different presentation for automated assembly. Selection between formats depends on manufacturing process requirements and volume handling capabilities, not component performance.

Q: Why is MCR006YRTF1101 listed as a substitute if it is discontinued?

A: MCR006YRTF1101 is included as a documented equivalent based on electrical and mechanical parameter matching. The discontinued status indicates it is no longer actively manufactured by Rohm Semiconductor at DiGi Electronics. Existing inventory may remain available through alternative distributors or secondary markets. This part is suitable for applications where current stock is accessible or for reference in legacy design documentation.

Q: What compliance certifications are maintained across all three parts?

A: All three parts (RC0603F112CS, CRCW02011K10FKED, MCR006YRTF1101) maintain ROHS3 compliance, indicating conformance to Restriction of Hazardous Substances regulations. All parts carry MSL 1 (Unlimited) moisture sensitivity level, requiring no special moisture control during storage or handling. REACH status is unaffected for all parts, and all carry ECCN classification EAR99 with HTSUS code 8533.21.0030.
