Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0711R8L is determined by the following critical parameters:

• Resistance value: Must be 11.8 Ohms
• Package type: Must be 0402 (1005 Metric)
• Composition: Must be thin film
• Power rating: Must be 0.063W (1/16W) or higher
• Operating temperature range: Must encompass -55°C to 155°C
• Termination count: Must be 2
• RoHS compliance: Must meet ROHS3 standard

The CPF0402B11R8E1 qualifies as a direct substitute because it matches all critical parameters while offering improved electrical performance characteristics (tighter tolerance and lower temperature coefficient).

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0711R8L and CPF0402B11R8E1 are active production components with full ROHS3 compliance and unlimited moisture sensitivity rating. The CPF0402B11R8E1 offers superior electrical performance with ±0.1% tolerance versus ±1%, and a lower temperature coefficient of ±25ppm/°C compared to ±50ppm/°C. Selection between these parts should be based on application tolerance requirements and thermal stability needs. Both components are suitable for applications requiring compliance with environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B11R8E1 be used as a direct replacement for RT0402FRE0711R8L?

A: Yes. Both components share identical resistance value, package type, power rating, operating temperature range, and physical dimensions. The substitute offers improved tolerance and temperature coefficient specifications.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use the 0402 (1005 Metric) package with identical physical dimensions of 0.039" L x 0.020" W and maximum seated height of 0.014" (0.35mm). PCB footprints are interchangeable.

Q: What is the significance of the tolerance difference?

A: The CPF0402B11R8E1 provides ±0.1% tolerance compared to the RT0402FRE0711R8L's ±1% tolerance. This tighter tolerance reduces resistance value variation and improves circuit accuracy in precision applications.

Q: How do the temperature coefficients compare?

A: The CPF0402B11R8E1 has a temperature coefficient of ±25ppm/°C, half that of the RT0402FRE0711R8L at ±50ppm/°C. This means the substitute maintains more stable resistance across the full operating temperature range of -55°C to 155°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the RT0402FRE0711R8L and CPF0402B11R8E1 are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: What is the moisture sensitivity rating for these components?

A: Both components have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life and no special moisture control requirements during storage or handling.
