RT0805FRE07549KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07549KL is a 549 kOhms ±1% thin film chip resistor manufactured by YAGEO in 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across -55°C to 155°C. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while offering improved tolerance specifications or enhanced reliability certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07549KL is determined by the following mandatory parameters:

• Resistance value: 549 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (equal or greater acceptable)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider range acceptable)
• RoHS compliance: ROHS3 or equivalent (required)

The ERA-6AEB5493V qualifies as a direct substitute by meeting all mandatory parameters. This part maintains identical resistance, package, power rating, and composition specifications while offering improved tolerance (±0.1% versus ±1%) and automotive-grade reliability certification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-6AEB5493V serves as a direct substitute for the RT0805FRE07549KL in applications where component specifications are interchangeable. Both parts maintain Active product status and full ROHS3 compliance. The ERA-6AEB5493V provides enhanced performance characteristics through tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), with automotive-grade AEC-Q200 certification. Selection between these parts depends on application requirements for tolerance precision and environmental qualification standards.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB5493V replace RT0805FRE07549KL in existing designs?

A: Yes. Both parts share identical resistance value (549 kOhms), package format (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). Physical dimensions and termination count are equivalent, enabling direct PCB substitution.

Q: What are the key differences between these parts?

A: The ERA-6AEB5493V offers improved tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). The Panasonic part includes AEC-Q200 automotive qualification, while the YAGEO part does not specify this certification.

Q: Are both parts suitable for high-precision applications?

A: The ERA-6AEB5493V is better suited for applications requiring tight tolerance control due to its ±0.1% specification. The RT0805FRE07549KL with ±1% tolerance is appropriate for general-purpose applications where wider tolerance is acceptable.

Q: Do these parts have identical moisture sensitivity ratings?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any package or footprint differences?

A: No. Both parts use 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.024" / 0.60mm).
