RC0603F750CS Equivalent & Substitute Parts

Part Overview

The RC0603F750CS is a 75 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.05W (1/20W) in a 0201 (0603 Metric) surface mount package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). The part is designed for applications requiring precision resistive elements in compact form factors with moisture resistance characteristics. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when supply chain diversification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F750CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 75 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Termination count: 2
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height (seated max): 0.010" (0.26mm)

Compliance Parameters:

• RoHS3 Compliant
• MSL 1 (Unlimited)
• REACH Unaffected
• ECCN: EAR99

The substitute part CRCW020175R0FKED from Vishay Dale meets all mandatory matching parameters and compliance requirements. Variations in temperature coefficient and maximum operating temperature do not disqualify substitution when the application operating range remains within the substitute's specified limits.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: RC0603F750CS (Samsung Electro-Mechanics)

Selection criteria:

• Active product status with established supply chain
• RoHS3 compliant for regulated applications
• MSL 1 rating permits unlimited shelf life without baking
• Moisture resistant thick film composition
• Current inventory: 1089 pieces

Substitute Part: CRCW020175R0FKED (Vishay Dale)

Selection criteria:

• Active product status with extended availability
• RoHS3 compliant with identical regulatory standing
• MSL 1 rating with unlimited moisture tolerance
• Superior temperature coefficient (±100ppm/°C vs ±250ppm/°C)
• Extended operating temperature range (-55°C to 155°C vs -55°C to 125°C)
• Current inventory: 35344 pieces
• Suitable for applications requiring tighter temperature stability or higher temperature operation within the substitute's specified range

Both parts are suitable for direct substitution in applications where the operating temperature does not exceed 125°C. For applications operating above 125°C but below 155°C, only CRCW020175R0FKED is appropriate. Selection between the two should be based on application temperature requirements, supply availability, and procurement lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can CRCW020175R0FKED replace RC0603F750CS in all applications?

A: CRCW020175R0FKED is a direct substitute for RC0603F750CS when the application operating temperature remains within -55°C to 125°C. The substitute part's extended temperature range (-55°C to 155°C) provides additional operational margin. Both parts are electrically and mechanically equivalent at 75 Ohms ±1%, 0.05W, 0201 package.

Q: What is the significance of the different temperature coefficients?

A: RC0603F750CS has a temperature coefficient of ±250ppm/°C, while CRCW020175R0FKED has ±100ppm/°C. The substitute exhibits superior temperature stability. For precision applications sensitive to resistance drift over temperature, CRCW020175R0FKED provides tighter tolerance maintenance across the operating range.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0.024" L x 0.012" W (0.60mm x 0.30mm) with a maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable in PCB layouts designed for 0201 (0603 Metric) packages.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC0603F750CS and CRCW020175R0FKED are RoHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (unlimited) moisture sensitivity ratings. They are equivalent for regulated applications.

Q: What is the difference in available inventory?

A: RC0603F750CS has 1089 pieces in stock, while CRCW020175R0FKED has 35344 pieces available. The substitute offers significantly higher inventory availability for high-volume production requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Both parts are pin-compatible, package-compatible, and electrically equivalent at the specified 75 Ohm ±1% rating. No design modifications are required for substitution.

Q: What packaging format is used for both parts?

A: Both RC0603F750CS and CRCW020175R0FKED are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
