Key Parameters

Substitute Part Grouping Explanation

Substitution of the CRL2010-FW-R050ELF is based on the following critical parameters:

• Resistance Value: 50 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package Type: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (maintained)

The CR2010-FW-R050ELF qualifies as a direct substitute. While the power rating is reduced from 0.75W to 0.5W, all other electrical and mechanical parameters remain identical. The substitute part is active in production status and extends the maximum operating temperature to 155°C.

Parameter Comparison

Engineering Selection Recommendations

The CR2010-FW-R050ELF is the appropriate substitute for the obsolete CRL2010-FW-R050ELF. Both parts maintain identical electrical characteristics (50 mOhms, ±1% tolerance, ±200ppm/°C temperature coefficient) and mechanical compatibility (2010 package, identical footprint and height). The substitute part is currently in active production status, ensuring supply chain continuity.

The reduced power rating (0.5W versus 0.75W) requires circuit-level evaluation to confirm thermal margin adequacy in the target application. The extended maximum operating temperature (155°C versus 125°C) provides additional thermal headroom in high-temperature environments. Both parts maintain equivalent compliance certifications (ROHS3, REACH Unaffected, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can CR2010-FW-R050ELF be used as a direct replacement for CRL2010-FW-R050ELF?

A: Yes, for applications where the 0.5W power rating is sufficient. All electrical parameters (resistance, tolerance, temperature coefficient) and mechanical dimensions are identical. PCB footprint compatibility is guaranteed.

Q: What is the primary difference between these parts?

A: The main difference is power rating (0.75W versus 0.5W) and product status (obsolete versus active). The substitute part also supports higher maximum operating temperature (155°C versus 125°C).

Q: Are the physical packages identical?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical dimensions (5.00mm x 2.50mm) and height (0.70mm maximum). No PCB layout modifications are required.

Q: Do compliance certifications differ between the parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Should I consider the power rating difference in my design?

A: Yes. Verify that your circuit's maximum power dissipation at the resistor does not exceed 0.5W. If your design requires the full 0.75W capability, alternative parts with higher power ratings in the same package should be evaluated.
