• Tolerance: ±1%
• Power rating: 0.25W (1/4W)

Physical Specifications:

• Package format: 0805 (2012 Metric)
• Number of terminations: 2
• Composition: Thick Film

Environmental & Compliance:

• Operating temperature range: minimum -55°C to 125°C
• RoHS3 compliance
• Moisture Sensitivity Level 1

Substitute parts must match all electrical specifications and package format. Operating temperature range and temperature coefficient may exceed the original specification without compromising compatibility. Compliance certifications must be maintained at ROHS3 level or higher.

Parameter Comparison

Engineering Selection Recommendations

The CRM0805-FX-R082ELF is a direct electrical and mechanical substitute for the CRL0805-FW-R082ELF. Both components are manufactured by Bourns Inc. and share identical resistance, tolerance, power rating, and package specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The CRM0805-FX-R082ELF provides enhanced performance characteristics compared to the original part. The temperature coefficient is improved at ±100ppm/°C versus ±200ppm/°C, and the maximum operating temperature extends to 155°C compared to 125°C. These enhancements do not introduce compatibility issues and are fully backward compatible with designs specified for the CRL0805-FW-R082ELF.

Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 rating. The substitute part is designated as a current sense resistor, indicating suitability for precision current measurement applications while maintaining all baseline electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CRM0805-FX-R082ELF be used as a direct replacement for the CRL0805-FW-R082ELF?

A: Yes. Both parts share identical resistance (82 mOhms), tolerance (±1%), power rating (0.25W), and 0805 package format. Electrical and mechanical compatibility is complete.

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

A: The CRL0805-FW-R082ELF has a temperature coefficient of ±200ppm/°C, while the CRM0805-FX-R082ELF has ±100ppm/°C. The substitute part exhibits superior temperature stability. This difference does not prevent substitution and may improve circuit performance in temperature-sensitive applications.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The CRM0805-FX-R082ELF operates from -55°C to 155°C, compared to -55°C to 125°C for the original part. The extended upper temperature limit is a performance enhancement that does not compromise compatibility with designs specified for the original temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both the CRL0805-FW-R082ELF and CRM0805-FX-R082ELF are ROHS3 compliant and carry Moisture Sensitivity Level 1 rating.

Q: What is the physical size difference between these parts?

A: Both parts use the 0805 (2012 Metric) package. The CRL0805-FW-R082ELF measures 0.079" L x 0.049" W (2.00mm x 1.25mm), while the CRM0805-FX-R082ELF measures 0.079" L x 0.047" W (2.00mm x 1.20mm). The width difference of 0.002" (0.05mm) is within standard PCB pad tolerance and does not affect board-level compatibility.

Q: Why is the original part listed as obsolete?

A: The CRL0805-FW-R082ELF is no longer in active production. The CRM0805-FX-R082ELF is the current active equivalent from Bourns Inc., offering identical electrical specifications with enhanced performance characteristics and assured long-term availability.
