RT0402FRE0788R7L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0788R7L is a 0402 (1005 Metric) thin film chip resistor manufactured by YAGEO, rated at 88.7 Ohms with ±1% tolerance and 0.063W (1/16W) power dissipation. This component is actively produced and widely used in precision analog circuits, signal conditioning, and measurement applications where stable resistance values are required across the operating temperature range of -55°C to 155°C. Substitute parts are identified to provide alternatives with improved tolerance specifications, enhanced temperature stability, or automotive-grade certifications while maintaining electrical and mechanical compatibility.

Optimal for precision measurement circuits and applications with stringent temperature stability requirements. ROHS3 compliant with active product status.

All substitute parts maintain identical electrical performance in terms of resistance value, power rating, and operating temperature range. Selection should be based on tolerance requirements, temperature stability needs, and any automotive or mission-critical certifications required by the application.

Frequently Asked Questions (FAQ)

Q: Can RT0402FRE0788R7L be directly replaced with CPF0402B88R7E1?

A: Yes. Both components share identical resistance value (88.7 Ω), power rating (0.063W), package type (0402), and operating temperature range (-55°C to 155°C). CPF0402B88R7E1 offers improved tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25 ppm/°C vs. ±50 ppm/°C), making it a direct upgrade for applications requiring tighter specifications.

Q: What is the difference between ERA-2AEB88R7X and other substitutes?

A: ERA-2AEB88R7X is the only substitute with automotive AEC-Q200 certification, making it suitable for automotive applications. Its maximum seated height is 0.40mm compared to 0.35mm for other options. Temperature coefficient and tolerance match CPF0402B88R7E1 at ±25 ppm/°C and ±0.1% respectively.

Q: Which substitute offers the best temperature stability?

A: RN73C1E88R7BTDF provides the lowest temperature coefficient at ±10 ppm/°C, compared to ±25 ppm/°C for CPF0402B88R7E1 and ERA-2AEB88R7X, and ±50 ppm/°C for the original RT0402FRE0788R7L. This makes it the optimal choice for precision analog circuits requiring maximum temperature stability.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts (CPF0402B88R7E1, ERA-2AEB88R7X, and RN73C1E88R7BTDF) are ROHS3 compliant, matching the compliance status of the original RT0402FRE0788R7L.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, all parts share the 0402 (1005 Metric) package footprint and identical termination configuration (2 terminations). Physical dimensions are compatible for standard PCB assembly processes. The maximum seated height variation (0.35mm to 0.40mm) is negligible for typical PCB designs.

Q: What is the moisture sensitivity level for substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited) rating, identical to the original RT0402FRE0788R7L, indicating no moisture sensitivity restrictions during storage or handling.
