RT0805FRE07340KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07340KL is a 340 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface-mount resistor is rated for 0.125W (1/8W) power dissipation and operates across -55°C to 155°C. The component is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection. As an active product with established supply availability, equivalent and substitute parts are identified based on matching resistance value, package form factor, and electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07340KL is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 340 kOhms (exact match required)
• Package form factor: 0805 (2012 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Secondary Compatibility Parameters:

• Tolerance: ±1% or better (lower tolerance values are acceptable)
• Power rating: 0.125W minimum (higher ratings are acceptable)
• Temperature coefficient: ±50ppm/°C or better
• MSL rating: 1 (Unlimited)

Two substitute parts meet these criteria with enhanced electrical specifications and certifications.

Parameter Comparison

Engineering Selection Recommendations

4-2176094-4 (TE Connectivity Passive Product): This direct substitute offers improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W) while maintaining identical package dimensions and operating temperature range. ROHS3 compliance and MSL 1 rating are preserved. The enhanced temperature coefficient (±25ppm/°C) provides superior stability. This part is suitable for applications requiring tighter tolerance specifications or higher thermal headroom.

ERA-6AEB3403V (Panasonic Electronic Components): This upgrade substitute combines ±0.1% tolerance and ±25ppm/°C temperature coefficient with automotive AEC-Q200 qualification. Power rating matches the original specification (0.125W). The AEC-Q200 certification indicates qualification for automotive-grade reliability and environmental stress testing. This part is appropriate for applications requiring automotive-grade components or enhanced reliability documentation.

Both substitutes maintain full electrical and mechanical compatibility with the original RT0805FRE07340KL within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can 4-2176094-4 replace RT0805FRE07340KL in all applications? A: Yes, within the electrical and thermal design margins of your circuit. The higher power rating (0.25W) and improved tolerance (±0.1%) make it a direct functional substitute. Verify that the circuit design does not depend on the original ±1% tolerance specification.

Q: What is the advantage of ERA-6AEB3403V over the other options? A: ERA-6AEB3403V carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental stress testing standards. The ±0.1% tolerance and ±25ppm/°C temperature coefficient provide enhanced precision and stability. Select this part for automotive applications or systems requiring documented reliability qualification.

Q: Are the physical dimensions identical across all three parts? A: All three parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height varies slightly: RT0805FRE07340KL and ERA-6AEB3403V are 0.024" (0.60mm), while 4-2176094-4 is 0.026" (0.65mm). This minimal difference does not affect PCB layout compatibility.

Q: What packaging formats are available? A: RT0805FRE07340KL and 4-2176094-4 are supplied in Tape & Reel (TR) format. ERA-6AEB3403V is available in Cut Tape (CT) and Digi-Reel® format. Confirm packaging requirements with your procurement process.

Q: Do all parts meet RoHS3 compliance? A: Yes, all three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions.
