RT0805FRE07357KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07357KL is a 357 kOhms ±1% thin film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This surface-mount device is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The component is ROHS3 compliant with MSL 1 rating and maintains active product status.

Equivalent and substitute parts are identified to address inventory availability, performance upgrades, or specific application requirements while maintaining electrical and mechanical compatibility within the 0805 package specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07357KL is determined by the following mandatory parameters:

• Resistance value: 357 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent
• RoHS compliance: ROHS3 or equivalent

Tolerance and power rating may vary within acceptable engineering margins. Temperature coefficient and additional certifications (such as AEC-Q200) represent performance enhancements rather than substitution barriers.

Two substitute parts meet these criteria:

1. 4-2176094-6 (TE Connectivity Passive Product): Direct substitute with improved tolerance (±0.1%) and higher power rating (0.25W). Temperature coefficient improved to ±25ppm/°C.

2. ERA-6AEB3573V (Panasonic Electronic Components): Upgrade substitute with improved tolerance (±0.1%), automotive-grade AEC-Q200 certification, and enhanced temperature coefficient (±25ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

RT0805FRE07357KL (YAGEO) remains the primary specification. This part is active, ROHS3 compliant, and meets all stated electrical and mechanical requirements.

4-2176094-6 (TE Connectivity Passive Product) serves as a direct substitute with performance enhancements. The improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W) provide margin for applications requiring tighter resistance accuracy or higher thermal dissipation. The reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) improves stability across the operating temperature range. Physical height increases marginally to 0.026" (0.65mm), which remains within typical PCB assembly tolerances. This part is ROHS3 compliant and active.

ERA-6AEB3573V (Panasonic Electronic Components) represents an upgrade substitute with automotive-grade AEC-Q200 certification. This certification indicates qualification for automotive applications with enhanced reliability requirements. The tolerance and temperature coefficient match the TE Connectivity part (±0.1% and ±25ppm/°C respectively), while maintaining the original 0.125W power rating and 0.024" (0.60mm) height. This part is ROHS3 compliant and active. Selection of this part is appropriate for applications requiring automotive-grade component qualification.

All three parts share identical resistance value, package format, composition, operating temperature range, and moisture sensitivity rating, ensuring direct electrical and mechanical compatibility within the 0805 form factor.

Frequently Asked Questions (FAQ)

Q: Can 4-2176094-6 be used as a direct replacement for RT0805FRE07357KL?

A: Yes. Both parts share identical resistance (357 kOhms), package (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The TE Connectivity part offers improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W). The physical height increases from 0.024" to 0.026", which remains within standard PCB assembly clearances.

Q: What is the difference between 4-2176094-6 and ERA-6AEB3573V?

A: Both parts provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. The primary difference is that ERA-6AEB3573V carries AEC-Q200 automotive certification, while 4-2176094-6 does not. The TE Connectivity part has a higher power rating (0.25W versus 0.125W) and slightly greater height (0.026" versus 0.024"). Selection depends on whether automotive qualification is required for the application.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts conform to the 0805 (2012 Metric) package specification with identical footprint dimensions (0.079" L x 0.049" W). Height variations (0.024" to 0.026") are within standard assembly tolerances and do not require layout modification. Solder pad and via spacing remain unchanged.

Q: Does tolerance difference affect circuit performance?

A: Tolerance affects the precision of the resistance value. The RT0805FRE07357KL provides ±1% tolerance, resulting in a resistance range of 353.57 kOhms to 360.43 kOhms. The substitute parts provide ±0.1% tolerance, resulting in a range of 356.643 kOhms to 357.357 kOhms. Applications requiring tighter resistance accuracy benefit from the substitute parts.

Q: Can ERA-6AEB3573V be used in non-automotive applications?

A: Yes. AEC-Q200 certification indicates automotive-grade reliability and does not restrict use in non-automotive applications. The part meets all electrical and mechanical requirements for general industrial and commercial use.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates resistance change per degree Celsius. The RT0805FRE07357KL has ±50ppm/°C, while both substitute parts have ±25ppm/°C. Lower temperature coefficient means the resistance value remains more stable across the -55°C to 155°C operating range, reducing drift in temperature-sensitive circuits.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for commercial and industrial applications.
