Substitute Part Grouping Explanation

Substitute parts for the RC0603J273CS are classified based on strict electrical and mechanical parameter alignment:

Upgrade Substitute (CRCW020127K0FKED): This Vishay Dale component maintains identical resistance value (27 kOhms), power rating (0.05W), package format (0201), and physical dimensions. The primary difference is improved tolerance specification (±1% versus ±5%), lower temperature coefficient (±100ppm/°C versus ±250ppm/°C), and extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C). This part qualifies as an upgrade substitute where tighter tolerance and improved thermal performance are acceptable or beneficial.

Similar Substitute (MCR006YRTJ273): This Rohm Semiconductor component matches the RC0603J273CS in resistance (27 kOhms), tolerance (±5%), power rating (0.05W), package (0201), physical dimensions, temperature coefficient (±250ppm/°C), and operating temperature range (-55°C ~ 125°C). This part is functionally equivalent with identical electrical specifications. Product status is Discontinued at DiGi Electronics; however, 7,620 pieces remain in stock.

Substitution Criteria: All substitute parts share the following mandatory parameters with the main part:

• Resistance value: 27 kOhms
• Power rating: 0.05W (1/20W)
• Package / Case: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Number of terminations: 2
• Composition: Thick Film
• RoHS3 Compliance
• MSL Level 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC0603J273CS): Recommended for new designs and standard applications. Active product status ensures long-term availability and supply chain stability. Samsung Electro-Mechanics manufacturing provides established quality and reliability documentation. ROHS3 compliance and MSL Level 1 rating support unrestricted use in moisture-sensitive environments.

Upgrade Selection (CRCW020127K0FKED): Select this Vishay Dale substitute when circuit design specifications require tighter tolerance control (±1% versus ±5%) or improved temperature stability (±100ppm/°C versus ±250ppm/°C). Extended operating temperature range (-55°C ~ 155°C) accommodates high-temperature applications beyond the RC0603J273CS capability. Active product status and higher inventory (27,308 pieces) support immediate procurement. ROHS3 compliance and MSL Level 1 rating maintain environmental and moisture handling standards.

Alternative Selection (MCR006YRTJ273): This Rohm Semiconductor part provides functional equivalence with identical electrical specifications (27 kOhms ±5%, ±250ppm/°C, -55°C ~ 125°C). Use this substitute only when inventory constraints or supply chain disruptions affect primary options. Product status is Discontinued at DiGi Electronics; verify long-term availability before design commitment. Existing stock of 7,620 pieces supports near-term requirements only. ROHS3 compliance and MSL Level 1 rating remain consistent with primary part.

Compliance Verification: All three parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications, ensuring regulatory and export compliance across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can CRCW020127K0FKED replace RC0603J273CS in existing designs without circuit modification?

A: Yes. Both parts share identical resistance (27 kOhms), power rating (0.05W), package format (0201), and physical dimensions (0.024" L x 0.012" W). The CRCW020127K0FKED offers improved tolerance (±1% versus ±5%) and lower temperature coefficient (±100ppm/°C versus ±250ppm/°C), which are compatible enhancements. No circuit modification is required.

Q: What is the key difference between the RC0603J273CS and CRCW020127K0FKED?

A: The primary differences are tolerance specification and temperature performance. CRCW020127K0FKED provides ±1% tolerance compared to ±5%, and ±100ppm/°C temperature coefficient compared to ±250ppm/°C. Operating temperature range extends to 155°C versus 125°C. These represent performance improvements suitable for precision and high-temperature applications.

Q: Is MCR006YRTJ273 a direct equivalent to RC0603J273CS?

A: Yes, MCR006YRTJ273 is a direct functional equivalent. Both parts share identical resistance (27 kOhms), tolerance (±5%), power rating (0.05W), package (0201), temperature coefficient (±250ppm/°C), and operating temperature range (-55°C ~ 125°C). However, MCR006YRTJ273 is Discontinued at DiGi Electronics; use only when primary options are unavailable.

Q: Are all three parts compatible with moisture-sensitive assembly processes?

A: Yes. All three parts carry MSL Level 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements. ROHS3 compliance is maintained across all substitutes, supporting standard PCB assembly and environmental standards.

Q: What packaging formats are available for these parts?

A: RC0603J273CS is supplied in Cut Tape (CT) format. CRCW020127K0FKED is supplied in Tape & Reel (TR) format. MCR006YRTJ273 is available in Cut Tape (CT) and Digi-Reel® format. Select packaging based on production volume and assembly equipment compatibility.

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

A: Only CRCW020127K0FKED supports operation up to 155°C. RC0603J273CS and MCR006YRTJ273 are rated to 125°C maximum. For applications requiring sustained operation above 125°C, CRCW020127K0FKED is the only qualified substitute.
