CRL0805-FW-R220ELF Equivalent & Substitute Parts

Part Overview

The CRL0805-FW-R220ELF is a 220 mOhms ±1% thick film chip resistor manufactured by Bourns Inc. in the 0805 (2012 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and operates across the temperature range of -55°C to 125°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when they share identical electrical specifications and compatible mechanical characteristics within the 0805 package family.

Substitute Part Grouping Explanation

Substitute parts for the CRL0805-FW-R220ELF are identified based on the following critical parameters:

• Resistance Value: 220 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package Format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity: MSL 1 (minimum requirement)

The RMCF0805FTR220 from Stackpole Electronics Inc. qualifies as a substitute part. While this part carries a lower power rating (0.125W vs. 0.25W) and an extended operating temperature range (-55°C to 155°C), it maintains all critical electrical parameters and package specifications. The reduced power rating represents a constraint that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

The RMCF0805FTR220 serves as a functional substitute for the CRL0805-FW-R220ELF in applications where the reduced power rating does not exceed circuit requirements. Both parts maintain Active product status, ROHS3 compliance, and identical electrical specifications for resistance, tolerance, and temperature coefficient.

The Stackpole part includes Automotive AEC-Q200 qualification, which provides additional reliability assurance for automotive-grade applications. The extended operating temperature range (-55°C to 155°C) of the RMCF0805FTR220 offers broader thermal coverage compared to the Bourns part (-55°C to 125°C).

The primary constraint for substitution is the power rating differential: the RMCF0805FTR220 is rated at 0.125W versus the CRL0805-FW-R220ELF at 0.25W. This difference must be evaluated against actual power dissipation requirements in the target application. The marginal height difference (0.026" vs. 0.024") is within typical PCB assembly tolerances for 0805 packages.

Frequently Asked Questions (FAQ)

Q: Can the RMCF0805FTR220 replace the CRL0805-FW-R220ELF in all applications?

A: Substitution is valid only when the application power dissipation does not exceed 0.125W. The RMCF0805FTR220 carries a lower power rating (1/8W vs. 1/4W). If the circuit requires the full 0.25W capacity of the original part, the Stackpole substitute is not appropriate.

Q: Are there differences in physical dimensions that affect PCB assembly?

A: Both parts use the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The seated height differs by 0.002" (0.026" vs. 0.024"), which is negligible for standard PCB assembly processes and does not affect footprint compatibility.

Q: What is the significance of the AEC-Q200 qualification on the RMCF0805FTR220?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. This certification is relevant only if the application requires automotive-grade components. For non-automotive applications, this feature provides no functional advantage.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the CRL0805-FW-R220ELF and RMCF0805FTR220 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. They are equivalent in regulatory compliance.

Q: What is the temperature coefficient, and why is it important?

A: Both parts have a temperature coefficient of ±200ppm/°C, meaning the resistance value changes by up to 200 parts per million for each degree Celsius change in operating temperature. This specification is identical between the two parts and does not affect substitution decisions.
