Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07143RL is determined by the following mandatory parameters:

• Resistance Value: Must be 143 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 cover -55°C to 155°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status
• MSL Rating: Must be Level 1 or equivalent

Tolerance and temperature coefficient may vary within acceptable ranges for substitute parts, provided the substitute meets or exceeds the performance envelope of the original specification. Two substitute parts meet these criteria with enhanced tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

CPF0402B143RE1 (TE Connectivity Passive Product): This substitute provides improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature specifications. Selection is appropriate for applications requiring tighter resistance tolerance and improved temperature stability. ROHS3 compliance and MSL Level 1 rating are maintained.

ERA-2AEB1430X (Panasonic Electronic Components): This substitute offers the same tolerance and temperature coefficient improvements as the TE Connectivity option, with the addition of AEC-Q200 automotive qualification. Selection is appropriate for automotive applications or designs requiring automotive-grade component reliability. All electrical and environmental specifications remain compatible with the original part.

Both substitute parts are active products with established supply availability and maintain full compliance with RoHS and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B143RE1 or ERA-2AEB1430X be used as direct replacements for RT0402FRE07143RL?

A: Yes. Both substitute parts maintain identical resistance value, package type, power rating, and operating temperature range. The improved tolerance and temperature coefficient specifications of the substitutes are compatible with applications designed for the original part.

Q: What is the difference between the two substitute parts?

A: CPF0402B143RE1 and ERA-2AEB1430X are electrically equivalent with identical tolerance (±0.1%) and temperature coefficient (±25ppm/°C) specifications. The primary distinction is that ERA-2AEB1430X carries AEC-Q200 automotive qualification, making it suitable for automotive applications where this certification is required.

Q: Does the improved tolerance of the substitute parts affect circuit design?

A: The ±0.1% tolerance of both substitutes is tighter than the ±1% tolerance of the original part. This represents an improvement in resistance accuracy and does not introduce incompatibility. Circuits designed for ±1% tolerance will function correctly with ±0.1% components.

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

A: All three parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W). The ERA-2AEB1430X has a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for the other parts. This minor difference does not affect standard PCB assembly processes.

Q: What is the significance of the AEC-Q200 rating on ERA-2AEB1430X?

A: AEC-Q200 is an automotive industry qualification standard for passive components. This rating indicates the part has been tested and qualified for automotive applications. Selection of ERA-2AEB1430X is necessary only if your application requires automotive-grade components or AEC-Q200 certification.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT0402FRE07143RL, CPF0402B143RE1, and ERA-2AEB1430X are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.
