Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC0603F431CS are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Primary Matching Parameters:

• Resistance value: 430 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package type: 0201 (0603 Metric)
• Composition: Thick Film
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Secondary Compatibility Parameters:

• Operating temperature range (minimum -55°C required)
• Temperature coefficient (within acceptable tolerance drift)
• Product status (Active or equivalent availability)

Parts are classified as Direct Equivalents when all primary parameters match exactly. Parts with identical primary specifications but different secondary parameters (such as temperature coefficient or maximum operating temperature) are classified as Similar equivalents, with differences explicitly noted.

Engineering Selection Recommendations

CRCW0201430RFKED (Vishay Dale) - Direct Equivalent

The CRCW0201430RFKED is a direct electrical and mechanical equivalent to the RC0603F431CS. All primary substitution parameters match exactly: 430 Ohms ±1%, 0.05W power rating, 0201 package, and identical physical dimensions. The part maintains ROHS3 compliance and MSL 1 rating. The Vishay Dale part features a superior temperature coefficient of ±100ppm/°C compared to the Samsung part's ±250ppm/°C, and an extended maximum operating temperature of 155°C versus 125°C. The part is currently Active in product status. Packaging is supplied as Tape & Reel (TR) format.

MCR006YRTF4300 (Rohm Semiconductor) - Similar Equivalent

The MCR006YRTF4300 matches all primary electrical and mechanical specifications: 430 Ohms ±1%, 0.05W power rating, 0201 package, and identical physical dimensions. RoHS3 compliance and MSL 1 rating are maintained. The temperature coefficient (±250ppm/°C) and operating temperature range (-55°C ~ 125°C) are identical to the Samsung part. However, this part is listed as Discontinued at DiGi Electronics, indicating limited future availability. Packaging is supplied as Cut Tape (CT) & Digi-Reel® format.

Selection Basis:

For applications requiring continued product availability and superior temperature stability, the CRCW0201430RFKED is the preferred substitute. For applications with existing supply chains or specific packaging requirements, the MCR006YRTF4300 remains functionally equivalent, subject to availability constraints.

Frequently Asked Questions (FAQ)

Q: Can CRCW0201430RFKED be used as a direct replacement for RC0603F431CS in PCB assembly?

A: Yes. Both parts share identical electrical specifications (430 Ohms ±1%, 0.05W), mechanical dimensions (0.024" L x 0.012" W), and package type (0201). Physical footprints are identical, and both parts are RoHS3 compliant with MSL 1 rating. No circuit redesign or PCB layout modification is required.

Q: What is the difference between the temperature coefficients of these parts?

A: The RC0603F431CS and MCR006YRTF4300 both have a temperature coefficient of ±250ppm/°C, while the CRCW0201430RFKED has ±100ppm/°C. This means the Vishay Dale part exhibits lower resistance drift across temperature variations, resulting in improved stability in temperature-sensitive applications. For applications operating across the full -55°C to 125°C range, this difference may be significant.

Q: Are there packaging differences between the substitute parts?

A: Yes. The RC0603F431CS is supplied in Cut Tape (CT) format. The CRCW0201430RFKED is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The MCR006YRTF4300 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format does not affect electrical or mechanical compatibility; it only impacts procurement and assembly logistics.

Q: Why is MCR006YRTF4300 listed as discontinued?

A: The MCR006YRTF4300 is discontinued at DiGi Electronics, indicating that this distributor no longer actively stocks or supports this part. However, the part remains functionally equivalent and may be available through alternative suppliers or existing inventory. For new designs, the CRCW0201430RFKED is recommended due to active product status and continued availability.

Q: Can these parts be used in high-temperature applications above 125°C?

A: The RC0603F431CS and MCR006YRTF4300 are rated for maximum operating temperature of 125°C. The CRCW0201430RFKED supports operation up to 155°C. For applications requiring operation above 125°C, only the CRCW0201430RFKED is suitable.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts—RC0603F431CS, CRCW0201430RFKED, and MCR006YRTF4300—are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, making them suitable for standard PCB assembly and storage conditions without special handling requirements.
