Parameter Comparison

Engineering Selection Recommendations

The CPF0402B11R3E1 manufactured by TE Connectivity Passive Product qualifies as a direct substitute for the RT0402FRE0711R3L. Both components maintain identical mechanical compatibility, identical power ratings, and identical operating temperature ranges. Both components carry Active product status and full RoHS3 compliance with MSL 1 rating.

The CPF0402B11R3E1 provides improved tolerance specification (±0.1% versus ±1%) and superior temperature coefficient performance (±25ppm/°C versus ±50ppm/°C). These enhancements represent performance upgrades suitable for applications requiring tighter resistance accuracy and improved thermal stability.

Selection between these components should be based on application requirements for tolerance and temperature coefficient performance, availability, and cost considerations. Both components are suitable for direct PCB substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the CPF0402B11R3E1 be used as a direct replacement for the RT0402FRE0711R3L?

A: Yes. Both components share identical 11.3 Ohm resistance, 0.063W power rating, 0402 package dimensions, and operating temperature range (-55°C ~ 155°C). Mechanical and electrical compatibility is confirmed. The CPF0402B11R3E1 offers tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C).

Q: Are there any PCB layout or soldering considerations when substituting these parts?

A: No. Both components use identical 0402 (1005 Metric) package specifications with matching footprint dimensions (0.039" L x 0.020" W) and maximum seated height (0.014"). Existing PCB layouts and assembly processes require no modification.

Q: What is the significance of the tolerance difference between these parts?

A: The CPF0402B11R3E1 tolerance of ±0.1% provides tighter resistance accuracy compared to the RT0402FRE0711R3L tolerance of ±1%. Applications requiring precise resistance values benefit from the improved tolerance specification. For applications with ±1% tolerance requirements, both components are functionally equivalent.

Q: Do both components meet the same compliance standards?

A: Yes. Both components are RoHS3 Compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are classified as EAR99 for export control purposes. Regulatory and environmental compliance is equivalent.

Q: What is the temperature coefficient and why does it matter?

A: Temperature coefficient measures resistance change per degree Celsius. The CPF0402B11R3E1 at ±25ppm/°C exhibits half the temperature-induced resistance drift compared to the RT0402FRE0711R3L at ±50ppm/°C. Applications operating across wide temperature ranges benefit from lower temperature coefficient values.
