RT0805FRE073K24L Equivalent & Substitute Parts

Part Overview

The RT0805FRE073K24L is a 3.24 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part is active in production status and ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate alternative tolerance or power rating specifications.

Substitute Part Grouping Explanation

Substitution of the RT0805FRE073K24L is determined by the following critical parameters: resistance value (3.24 kOhms), package type (0805), composition (thin film), and operating temperature range (-55°C to 155°C). Parts are grouped into three categories based on tolerance and power rating specifications:

Upgrade Tolerance Parts (±0.1% tolerance): RT0805BRD073K24L and ERA-6AEB3241V provide tighter tolerance specifications while maintaining identical resistance, package, and power rating. These parts are direct functional upgrades suitable for applications requiring higher precision.

Intermediate Tolerance Part (±0.5% tolerance): RT0805DRE073K24L offers a tolerance specification between the main part and upgrade options, maintaining all other electrical characteristics.

Higher Power Rating Part (0.25W): 6-2176092-1 from TE Connectivity maintains the same resistance, tolerance (±0.1%), and package but provides increased power dissipation capability (0.25W versus 0.125W).

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance and identical operating temperature ranges (-55°C to 155°C). Selection between substitutes depends on application-specific requirements:

RT0805BRD073K24L is suitable for applications requiring improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) while maintaining the same power rating as the original part.

RT0805DRE073K24L provides an intermediate tolerance option (±0.5%) when tighter specifications than ±1% are needed but ±0.1% is not required.

6-2176092-1 is appropriate for circuits where power dissipation exceeds 0.125W but remains within 0.25W capacity. This part maintains ±0.1% tolerance and ±25ppm/°C temperature coefficient.

ERA-6AEB3241V is specified for automotive applications requiring AEC-Q200 qualification. It provides ±0.1% tolerance and ±25ppm/°C temperature coefficient in the same 0.125W power rating.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD073K24L replace RT0805FRE073K24L directly? A: Yes. Both parts share identical resistance (3.24 kOhms), power rating (0.125W), package (0805), and operating temperature range. RT0805BRD073K24L provides improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between RT0805DRE073K24L and RT0805BRD073K24L? A: Both are YAGEO thin film resistors with 3.24 kOhms resistance and 0.125W power rating in 0805 package. RT0805DRE073K24L has ±0.5% tolerance, while RT0805BRD073K24L has ±0.1% tolerance. RT0805BRD073K24L also features a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Q: Can 6-2176092-1 be used in place of RT0805FRE073K24L? A: Yes, with consideration for physical dimensions. Both parts are 0805 package with 3.24 kOhms resistance and ±0.1% tolerance. The TE Connectivity part has a maximum seated height of 0.026" (0.65mm) versus 0.024" (0.60mm) for the YAGEO part, and provides higher power rating (0.25W versus 0.125W). Verify PCB layout clearance before substitution.

Q: Is ERA-6AEB3241V suitable for non-automotive applications? A: Yes. ERA-6AEB3241V meets all electrical specifications for the 3.24 kOhms 0805 resistor requirement. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits. It provides ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures. All listed substitute parts share this MSL rating, requiring no special storage or handling precautions.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RT0805FRE073K24L and all listed substitutes (RT0805BRD073K24L, RT0805DRE073K24L, 6-2176092-1, and ERA-6AEB3241V) are ROHS3 compliant.
