Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603J111CS is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance Value: 110 Ohms (exact match required)
• Package / Case: 0201 (0603 Metric) (mechanical compatibility)
• Power Rating: 0.05W minimum (thermal capacity)
• Composition: Thick Film (construction method)
• RoHS3 Compliance: Required (regulatory requirement)
• MSL Rating: 1 or equivalent (handling and storage)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±5% or better)
• Temperature Coefficient: May be lower (improved stability)
• Operating Temperature Range: May be equal or extended (broader capability)

The identified substitute CRCW0201110RFKED from Vishay Dale meets all mandatory parameters with improved tolerance specification (±1% versus ±5%) and extended upper operating temperature limit (155°C versus 125°C), representing an upgrade-compatible alternative.

Parameter Comparison

Engineering Selection Recommendations

RC0603J111CS (Samsung Electro-Mechanics) is the primary specification component. Selection is appropriate when:

• Design tolerance requirement is ±5% or broader
• Operating temperature maximum does not exceed 125°C
• Standard temperature coefficient performance (±250ppm/°C) is acceptable
• Samsung supply chain and inventory availability are prioritized

CRCW0201110RFKED (Vishay Dale) is a direct substitute with performance enhancements. Selection is appropriate when:

• Tighter tolerance specification (±1%) is required or beneficial
• Operating temperature may reach or exceed 125°C up to 155°C
• Lower temperature coefficient (±100ppm/°C) improves circuit stability
• Vishay Dale supply chain availability is preferred
• Design specifications permit component upgrade

Both parts maintain identical mechanical compatibility, identical power rating, identical package form factor, and equivalent regulatory compliance (ROHS3, MSL 1). Substitution is electrically and mechanically valid in either direction within the stated parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can CRCW0201110RFKED replace RC0603J111CS in existing designs?

A: Yes. The CRCW0201110RFKED is mechanically and electrically compatible. It features identical package dimensions (0201 / 0603 Metric), identical power rating (0.05W), and identical resistance value (110 Ohms). The substitute offers tighter tolerance (±1% versus ±5%) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C), making it a direct upgrade-compatible alternative.

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

A: The primary differences are tolerance specification and temperature performance. The RC0603J111CS has ±5% tolerance and ±250ppm/°C temperature coefficient with 125°C maximum operating temperature. The CRCW0201110RFKED has ±1% tolerance and ±100ppm/°C temperature coefficient with 155°C maximum operating temperature. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC0603J111CS and CRCW0201110RFKED are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting identical regulatory and environmental handling requirements.

Q: Can RC0603J111CS replace CRCW0201110RFKED?

A: Substitution in this direction requires design review. The RC0603J111CS has broader tolerance (±5% versus ±1%) and lower maximum operating temperature (125°C versus 155°C). If the design specification requires ±1% tolerance or operation above 125°C, the RC0603J111CS does not meet those requirements. If the design permits ±5% tolerance and operates within -55°C to 125°C, substitution is valid.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts are packaged in 0201 (0603 Metric) with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and identical maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCB layouts.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient measures resistance drift with temperature change. The RC0603J111CS has ±250ppm/°C while CRCW0201110RFKED has ±100ppm/°C. Lower temperature coefficient indicates better stability across temperature variations. For precision circuits or wide temperature range applications, the lower coefficient of CRCW0201110RFKED provides superior performance.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both RC0603J111CS and CRCW0201110RFKED are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
