RT0402FRE0747R5L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0747R5L is a 47.5 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This component is actively produced and widely used in precision analog circuits requiring stable resistance values across temperature ranges from -55°C to 155°C. Finding equivalent or substitute parts may be necessary due to supply chain considerations, inventory availability, or application-specific requirements such as tighter tolerance specifications or automotive-grade reliability certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0747R5L is determined by the following critical parameters:

• Resistance Value: Must be 47.5 Ohms
• Package Type: Must be 0402 (1005 Metric)
• Composition: Must be Thin Film
• Power Rating: Must be 0.063W (1/16W) minimum
• Operating Temperature Range: Must cover -55°C to 155°C
• RoHS Compliance: Must be ROHS3 Compliant

The identified substitute parts meet all mandatory electrical and mechanical parameters. Two alternatives are available: CPF0402B47R5E1 from TE Connectivity Passive Product and ERA-2AEB47R5X from Panasonic Electronic Components. Both maintain the same resistance value, package footprint, and power rating while offering enhanced tolerance specifications (±0.1% versus ±1%) and improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are functionally compatible with the RT0402FRE0747R5L based on electrical and mechanical specifications. Selection between alternatives depends on application requirements:

CPF0402B47R5E1 offers improved tolerance (±0.1%) and temperature coefficient (±25ppm/°C) performance while maintaining identical package dimensions and height specifications. This part is suitable for general precision applications requiring tighter resistance tolerances.

ERA-2AEB47R5X provides the same tolerance and temperature coefficient improvements as the TE Connectivity alternative, with the additional qualification of AEC-Q200 automotive-grade reliability. The seated height is 0.016" (0.40mm) compared to 0.014" (0.35mm) for the main part and TE Connectivity substitute. This part is appropriate for automotive and mission-critical applications requiring automotive-grade component certification.

All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B47R5E1 be used as a direct replacement for RT0402FRE0747R5L?

A: Yes. Both parts share identical resistance value (47.5 Ohms), package type (0402), power rating (0.063W), and operating temperature range (-55°C to 155°C). The CPF0402B47R5E1 offers superior tolerance (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a compatible upgrade.

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

A: CPF0402B47R5E1 and ERA-2AEB47R5X are electrically equivalent with identical tolerance and temperature coefficient specifications. The primary difference is that ERA-2AEB47R5X carries AEC-Q200 automotive qualification and has a maximum seated height of 0.016" (0.40mm) versus 0.014" (0.35mm) for the TE Connectivity part. Select ERA-2AEB47R5X for automotive applications requiring AEC-Q200 certification.

Q: Will the 0.002" (0.05mm) height difference of ERA-2AEB47R5X affect PCB assembly?

A: The height difference is within typical PCB assembly tolerances. However, verify clearance requirements for your specific application, particularly if components are mounted near low-profile connectors or shielding structures.

Q: Are all three parts RoHS compliant?

A: Yes. RT0402FRE0747R5L, CPF0402B47R5E1, and ERA-2AEB47R5X are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Can I use these parts interchangeably in the same design?

A: Yes, provided your application does not require automotive-grade certification. If AEC-Q200 qualification is mandatory, use only ERA-2AEB47R5X. For general applications, all three parts are mechanically and electrically interchangeable at the PCB level.
