Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F273CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27 kOhms (exact match required)
• Tolerance: ±1% (no deviation permitted)
• Power rating: 0.05W / 1/20W (thermal equivalence)
• Package: 0201 (0603 Metric) (physical and electrical compatibility)
• Composition: Thick Film (technology platform consistency)
• Termination count: 2 (standard configuration)

Acceptable Variation Parameters:

• Temperature coefficient: RC0603F273CS operates at ±250ppm/°C; CRCW020127K0FKED operates at ±100ppm/°C (substitute provides superior temperature stability)
• Operating temperature range: RC0603F273CS rated -55°C ~ 125°C; CRCW020127K0FKED rated -55°C ~ 155°C (substitute provides extended upper temperature limit)

Compliance Requirements:

• RoHS3 compliance (both parts meet requirement)
• MSL 1 rating (both parts meet requirement)
• REACH Unaffected status (both parts meet requirement)

The CRCW020127K0FKED from Vishay Dale qualifies as a direct substitute based on identical electrical specifications and package form factor, with enhanced performance characteristics in temperature stability and operating range.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RC0603F273CS): The RC0603F273CS remains the specified component for applications where the original design parameters are maintained. This part carries Active product status with established supply availability (721 pcs in stock) and meets all regulatory requirements including RoHS3 compliance and REACH unaffected status.

Substitute Part Selection (CRCW020127K0FKED): The CRCW020127K0FKED from Vishay Dale is selected as the equivalent substitute when supply constraints affect the primary part. This substitution is valid based on:

• Identical electrical specifications (27 kOhms ±1%, 0.05W)
• Identical physical package (0201 / 0603 Metric)
• Identical composition (Thick Film)
• Full regulatory compliance (RoHS3, REACH Unaffected)
• Enhanced performance characteristics (lower temperature coefficient ±100ppm/°C vs ±250ppm/°C; extended operating range to 155°C vs 125°C)
• Superior inventory availability (27,308 pcs in stock)

Both parts are classified as Active products with unlimited moisture sensitivity rating (MSL 1), ensuring compatibility in standard manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: Can CRCW020127K0FKED be used as a direct replacement for RC0603F273CS in production?

A: Yes. Both parts meet identical electrical specifications (27 kOhms ±1%, 0.05W), use the same package form factor (0201 / 0603 Metric), and comply with all regulatory requirements (RoHS3, REACH Unaffected). The substitute part provides enhanced temperature stability and extended operating range.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Samsung vs. Vishay Dale) and performance enhancements in the substitute. The CRCW020127K0FKED features a lower temperature coefficient (±100ppm/°C vs. ±250ppm/°C) and extended maximum operating temperature (155°C vs. 125°C). All other electrical and physical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.024" L x 0.012" W (0.60mm x 0.30mm) with a maximum seated height of 0.010" (0.26mm). They are fully compatible for PCB placement and soldering processes.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both RC0603F273CS and CRCW020127K0FKED carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or manufacturing.

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

A: The CRCW020127K0FKED is suitable for applications requiring operation up to 155°C, compared to the RC0603F273CS maximum of 125°C. However, both parts meet the specified operating range of -55°C ~ 125°C for standard applications.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are RoHS3 compliant, REACH Unaffected, and carry EAR99 ECCN classification with identical HTSUS codes (8533.21.0030).

Q: Can these parts be mixed in the same production batch?

A: Yes. Both parts are electrically and physically equivalent, carry identical regulatory compliance, and are classified as Active products. They may be used interchangeably within the same design without circuit modification.
