Substitute Part Grouping Explanation

Substitution of CRL2010-FW-4R70ELF with CR2010-F/-4R70ELF is based on the following critical parameters:

• Resistance Value: Both parts specify 4.7 Ohms with ±1% tolerance
• Package Format: Both use 2010 (5025 Metric) package with identical physical dimensions (0.197" L x 0.098" W, 0.028" max height)
• Composition: Both are thick film resistors
• Temperature Coefficient: Both maintain ±200ppm/°C
• Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited)
• Termination Count: Both have 2 terminations

The primary difference is power rating: CRL2010-FW-4R70ELF is rated at 0.75W while CR2010-F/-4R70ELF is rated at 0.5W. The substitute part operates within a wider temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C) and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

CR2010-F/-4R70ELF is the direct substitute for CRL2010-FW-4R70ELF based on the following factors:

• Both parts are manufactured by Bourns Inc. and maintain identical electrical specifications (4.7 Ohms ±1%, ±200ppm/°C)
• Physical footprint and package dimensions are identical, ensuring PCB compatibility without layout modifications
• Both parts meet ROHS3 compliance and carry MSL 1 rating
• CR2010-F/-4R70ELF maintains active product status with current manufacturing and availability
• The substitute part offers extended operating temperature range (-55°C ~ 155°C)

The 0.5W power rating of the substitute part is lower than the original 0.75W specification. Component selection must ensure that circuit power dissipation requirements do not exceed 0.5W at the specified resistance value.

Frequently Asked Questions (FAQ)

Q: Can CR2010-F/-4R70ELF be used as a direct replacement for CRL2010-FW-4R70ELF?

A: Yes, for applications where power dissipation does not exceed 0.5W. Both parts share identical resistance value, tolerance, package dimensions, and thermal coefficient. PCB layout and footprint remain unchanged.

Q: What is the primary limitation when substituting with CR2010-F/-4R70ELF?

A: The substitute part has a lower power rating (0.5W vs. 0.75W). Circuit designs must ensure that actual power dissipation at 4.7 Ohms remains within the 0.5W limit.

Q: Are the package dimensions identical between both parts?

A: Yes. Both parts use 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both CRL2010-FW-4R70ELF and CR2010-F/-4R70ELF are ROHS3 compliant with MSL 1 (Unlimited) rating.

Q: What is the temperature operating range difference?

A: CRL2010-FW-4R70ELF operates from -55°C to 125°C, while CR2010-F/-4R70ELF operates from -55°C to 155°C. The substitute part supports a wider high-temperature range.

Q: Is the packaging format different between the two parts?

A: The main part (CRL2010-FW-4R70ELF) is supplied in standard packaging, while the substitute (CR2010-F/-4R70ELF) is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.
