RT0402FRE07523RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07523RL is a 523 Ohm thin film chip resistor manufactured by YAGEO in 0402 (1005 Metric) package format. This component is rated at 1/16W (0.063W) with ±1% tolerance and operates across -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to address inventory availability, enhanced tolerance specifications, or automotive-grade requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following parameters: resistance value (523 Ohms), package format (0402/1005 Metric), power rating (0.063W minimum), composition (thin film), operating temperature range (-55°C to 155°C minimum), and compliance certifications (ROHS3, MSL 1). All identified substitutes maintain these core electrical and mechanical specifications. Tolerance and temperature coefficient variations represent performance enhancements rather than functional incompatibilities. Physical dimensions remain consistent across all listed alternatives, ensuring PCB layout compatibility without redesign.

Engineering Selection Recommendations

RT0402BRD07523RL (YAGEO) serves as a direct upgrade path, offering improved tolerance (±0.1% vs ±1%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical package geometry and power rating. This option is suitable for applications requiring tighter resistance accuracy without automotive qualification requirements.

CPF0402B523RE1 (TE Connectivity Passive Product) provides equivalent performance specifications to the YAGEO upgrade option with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Selection of this alternative depends on supply chain preferences and TE Connectivity component availability within procurement channels.

ERA-2AEB5230X (Panasonic Electronic Components) incorporates AEC-Q200 automotive qualification, making it the appropriate selection for automotive applications or systems requiring automotive-grade component certification. This part maintains ±0.1% tolerance and ±25ppm/°C temperature coefficient with a maximum seated height of 0.016" (0.40mm), representing a 0.002" increase compared to other alternatives. All parts maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07523RL replace RT0402FRE07523RL in any application? A: Yes. Both parts share identical resistance value (523 Ohms), package format (0402), power rating (0.063W), operating temperature range (-55°C to 155°C), and compliance certifications. The RT0402BRD07523RL offers superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it functionally compatible for direct substitution.

Q: What is the difference between the three substitute parts? A: All three substitutes maintain identical resistance, package, and power specifications. RT0402BRD07523RL and CPF0402B523RE1 differ only by manufacturer (YAGEO vs TE Connectivity). ERA-2AEB5230X adds AEC-Q200 automotive qualification and has a maximum seated height of 0.016" (0.40mm) versus 0.014" (0.35mm) for the other options.

Q: Is ERA-2AEB5230X suitable for non-automotive applications? A: Yes. AEC-Q200 certification represents an additional qualification level and does not restrict use in non-automotive circuits. The part meets all electrical and mechanical requirements for general-purpose applications.

Q: Will substituting these parts require PCB layout changes? A: No. All substitute parts maintain the 0402 (1005 Metric) package format with identical length and width dimensions (0.039" x 0.020"). ERA-2AEB5230X has a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for other options; verify clearance in height-constrained applications.

Q: Are all parts ROHS3 compliant? A: Yes. RT0402FRE07523RL, RT0402BRD07523RL, CPF0402B523RE1, and ERA-2AEB5230X all maintain ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.
