RT0603FRE0784R5L Equivalent & Substitute Parts

Part Overview

The RT0603FRE0784R5L is a 0603 (1608 Metric) thin film chip resistor manufactured by YAGEO, rated at 84.5 Ohms with ±1% tolerance and 0.1W 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 when equivalent electrical performance, mechanical compatibility, and compliance certifications align with the original specification.

Substitute Part Grouping Explanation

Substitute parts for the RT0603FRE0784R5L are qualified based on the following criteria:

• Resistance Value: Exact match at 84.5 Ohms
• Package / Case: Identical 0603 (1608 Metric) form factor
• Power Rating: Equal or greater at 0.1W minimum
• Composition: Thin film construction
• Operating Temperature Range: Minimum -55°C to 155°C coverage
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

Two substitute parts meet these criteria with enhanced tolerance specifications and automotive-grade qualification available.

Parameter Comparison

Engineering Selection Recommendations

RT0603BRD0784R5L provides a direct upgrade path within the YAGEO RT series. This part maintains identical mechanical and thermal characteristics while offering improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating. Selection of this substitute is appropriate for applications requiring tighter resistance tolerance without changing supplier or package specifications.

ERA-3AEB84R5V is a Panasonic equivalent qualified to AEC-Q200 automotive standards. This part delivers the same tolerance and temperature coefficient improvements as the RT0603BRD0784R5L while adding automotive-grade reliability certification. The ERA-3A series maintains identical package dimensions, power rating, and operating temperature range. Selection of this substitute is appropriate for automotive applications or systems requiring automotive-grade component qualification.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0784R5L be used as a direct replacement for RT0603FRE0784R5L?

A: Yes. Both parts share identical resistance value (84.5 Ohms), package (0603), power rating (0.1W), and operating temperature range (-55°C to 155°C). The RT0603BRD0784R5L offers improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), making it suitable for applications where the original tolerance specification is acceptable or where tighter tolerance is beneficial.

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

A: RT0603BRD0784R5L is a standard industrial-grade thin film resistor from YAGEO. ERA-3AEB84R5V is an automotive-grade equivalent from Panasonic qualified to AEC-Q200 standards. Both offer identical electrical performance (84.5 Ohms ±0.1%, ±25ppm/°C). Selection depends on application requirements: use RT0603BRD0784R5L for general industrial applications, or ERA-3AEB84R5V for automotive or mission-critical systems requiring automotive qualification.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts use the 0603 (1608 Metric) package with identical dimensions (0.063" L × 0.031" W, 1.60mm × 0.80mm) and maximum seated height (0.022", 0.55mm). They are mechanically interchangeable on standard PCB layouts designed for 0603 components.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity). ERA-3AEB84R5V additionally carries AEC-Q200 automotive qualification. All parts are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Which substitute should I select for a new design?

A: Selection depends on application class. For general industrial applications, RT0603BRD0784R5L provides improved tolerance and temperature stability at standard industrial grade. For automotive applications or systems requiring automotive-grade component qualification, ERA-3AEB84R5V is the appropriate selection. Both substitutes are actively produced with strong inventory availability.
