Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete CRL1206-FW-R068ELF is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 68 mOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Termination count: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Temperature coefficient: The substitute part may have a lower (improved) temperature coefficient value
• Operating temperature range: The substitute part may have an extended upper temperature limit
• Physical dimensions: Minor variations within the 1206 package specification are acceptable
• Product status: Active parts are preferred over obsolete classifications

The CRM1206-FX-R068ELF meets all mandatory matching criteria and qualifies as a direct substitute with enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The CRM1206-FX-R068ELF is the direct substitute for the obsolete CRL1206-FW-R068ELF. Both parts are manufactured by Bourns Inc. and share identical electrical specifications for resistance, tolerance, and power rating. The substitute part offers enhanced performance characteristics with a lower temperature coefficient (±100ppm/°C versus ±200ppm/°C) and an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C).

Both parts maintain ROHS3 compliance and MSL rating 1 status, ensuring compatibility with standard manufacturing and assembly processes. The substitute part is currently in active production status, providing long-term availability and supply chain stability compared to the obsolete main part.

Physical dimensions are within acceptable tolerances for the 1206 package specification, with the substitute part featuring slightly reduced length and height while maintaining identical width. These dimensional variations do not impact PCB layout or assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CRM1206-FX-R068ELF be used as a direct replacement for the CRL1206-FW-R068ELF?

A: Yes. Both parts share identical resistance (68 mOhms), tolerance (±1%), power rating (0.5W), package type (1206), composition (thick film), and compliance certifications. The substitute part is electrically and mechanically compatible.

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

A: The substitute part features a lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), an extended operating temperature range (up to 155°C versus 125°C), and slightly reduced physical dimensions. The substitute part is also in active production status.

Q: Are there any PCB layout considerations when switching to the CRM1206-FX-R068ELF?

A: No. Both parts use the 1206 (3216 Metric) package with identical width (0.063"). The substitute part is slightly shorter in length and height, which presents no compatibility issues for standard PCB designs.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Why is the substitute part preferred despite the main part being in stock?

A: The main part is classified as obsolete, which indicates discontinued production and limited future availability. The substitute part is in active production, ensuring long-term supply chain continuity and procurement reliability.

Q: Are the thermal characteristics of the substitute part suitable for high-temperature applications?

A: The substitute part operates to 155°C, providing a 30°C higher maximum temperature rating than the main part. The improved temperature coefficient (±100ppm/°C) also provides better stability across the operating range.
