Substitute Part Grouping Explanation

Substitution of the CRL0805-FW-R068ELF is based on electrical and mechanical parameter equivalence within the 0805 thick film resistor category. The primary substitute, CRM0805-FX-R068ELF, maintains identical resistance value (68 mOhms), tolerance (±1%), power rating (0.25W), package format (0805), and composition (thick film). Both parts satisfy the same electrical requirements and physical footprint constraints.

The substitution is valid based on the following matching parameters:

• Resistance: 68 mOhms (identical)
• Tolerance: ±1% (identical)
• Power Rating: 0.25W (identical)
• Package: 0805 (2012 Metric) (identical)
• Composition: Thick Film (identical)
• Termination Count: 2 (identical)
• RoHS Compliance: ROHS3 (identical)
• Moisture Sensitivity: MSL 1 (identical)

Parameter Comparison

Engineering Selection Recommendations

The CRM0805-FX-R068ELF serves as the direct substitute for the obsolete CRL0805-FW-R068ELF. Selection of the substitute part is supported by the following factors:

Product Status: The CRM0805-FX-R068ELF maintains active product status with Bourns Inc., ensuring continued availability and supply chain support. The original CRL0805-FW-R068ELF is classified as obsolete, making the substitute necessary for ongoing procurement.

Electrical Equivalence: Both parts deliver identical electrical performance with 68 mOhms resistance, ±1% tolerance, and 0.25W power rating. The substitute exhibits superior temperature stability with ±100ppm/°C coefficient compared to the original ±200ppm/°C specification.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

Physical Compatibility: The 0805 package format, termination count, and maximum seated height are identical, ensuring direct footprint compatibility on printed circuit boards. Minor dimensional variations in width (1.25mm versus 1.20mm) remain within standard 0805 package tolerances.

Extended Operating Range: The substitute part supports an extended upper operating temperature limit of 155°C compared to the original 125°C, providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the CRM0805-FX-R068ELF be used as a direct replacement for the CRL0805-FW-R068ELF?

A: Yes. Both parts share identical resistance (68 mOhms), tolerance (±1%), power rating (0.25W), package format (0805), and composition (thick film). The substitute is electrically and mechanically compatible for direct board-level substitution.

Q: What is the primary difference between these two parts?

A: The CRL0805-FW-R068ELF is obsolete, while the CRM0805-FX-R068ELF is active product. The substitute offers improved temperature coefficient (±100ppm/°C versus ±200ppm/°C) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). The substitute also includes current sense functionality designation.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format. Both maintain identical 0805 package dimensions and footprint. The width dimension differs slightly (1.25mm versus 1.20mm), remaining within standard 0805 tolerances.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the CRL0805-FW-R068ELF and CRM0805-FX-R068ELF are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory standards.

Q: Is the substitute part suitable for high-temperature applications?

A: The CRM0805-FX-R068ELF supports operating temperatures up to 155°C, compared to 125°C for the original part. This extended range makes the substitute suitable for applications requiring higher thermal performance.

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

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
