• Identical ECCN and HTSUS classifications

The CRM0805-FX-R075ELF represents an enhanced alternative with improved temperature coefficient (±100ppm/°C versus ±200ppm/°C) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C), while maintaining all core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CRM0805-FX-R075ELF is the appropriate substitute for the obsolete CRL0805-FW-R075ELF based on the following engineering criteria:

Product Status & Availability: The CRM0805-FX-R075ELF maintains active product status, ensuring continued availability and supply chain reliability. The CRL0805-FW-R075ELF is designated obsolete, presenting potential procurement challenges.

Electrical & Mechanical Compatibility: Both parts share identical electrical specifications (75 mOhms, ±1%, 0.25W) and mechanical form factor (0805 package). The substitute part maintains full compatibility with existing PCB layouts and assembly processes.

Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements. No compliance barriers exist for substitution in regulated applications.

Performance Enhancement: The CRM0805-FX-R075ELF provides improved temperature stability (±100ppm/°C versus ±200ppm/°C) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C), offering superior performance margins in thermal environments.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) format, standard for automated assembly operations. Dimensional variations (width: 1.20mm versus 1.25mm) remain within 0805 package tolerance specifications and do not affect PCB placement or functionality.

Frequently Asked Questions (FAQ)

Q: Can the CRM0805-FX-R075ELF directly replace the CRL0805-FW-R075ELF in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (75 mOhms), tolerance (±1%), power rating (0.25W), and package designation (0805). The substitute part is compatible with existing PCB layouts and assembly processes without design modification.

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

A: The primary differences are product status and thermal specifications. The CRM0805-FX-R075ELF is active production status versus obsolete for the CRL0805-FW-R075ELF. The substitute offers improved temperature coefficient (±100ppm/°C versus ±200ppm/°C) and extended operating range (-55°C to 155°C versus -55°C to 125°C). Physical width differs slightly (1.20mm versus 1.25mm), remaining within 0805 package specifications.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN and HTSUS classifications. Substitution presents no regulatory or environmental compliance barriers.

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

A: The CRM0805-FX-R075ELF exhibits half the temperature coefficient (±100ppm/°C) compared to the CRL0805-FW-R075ELF (±200ppm/°C). This indicates superior resistance stability across temperature variations, beneficial in precision current-sensing and measurement applications.

Q: Does the Tape & Reel packaging of the substitute affect compatibility?

A: No. Tape & Reel (TR) packaging is standard for automated surface mount assembly. The packaging format does not affect electrical performance or PCB compatibility. Component dimensions and termination specifications remain identical.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. Standard handling and storage procedures apply without special desiccant or humidity control requirements.

Q: Are the physical dimensions of the substitute compatible with 0805 footprints?

A: Yes. The substitute width (1.20mm) versus original width (1.25mm) represents a 0.05mm reduction, well within 0805 (2012 Metric) package tolerance specifications. Height and length remain identical. PCB footprints designed for 0805 components accommodate both parts without modification.
