Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE0741K2L are qualified based on the following criteria:

Core Matching Parameters:

• Resistance value: 41.2 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 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Allowable Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Power rating: 0.125W or higher (0.25W acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or tighter (±25ppm/°C acceptable as upgrade)
• Manufacturer: Different manufacturers permitted if all core parameters match

Three substitute parts meet these criteria: RT0805BRD0741K2L (YAGEO), 5-2176093-9 (TE Connectivity), and ERA-6AEB4122V (Panasonic).

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0741K2L (YAGEO Upgrade): This part offers improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical power rating and package dimensions. Both parts are YAGEO products with active production status and ROHS3 compliance. Selection is appropriate for applications requiring tighter resistance tolerance and improved temperature stability.

5-2176093-9 (TE Connectivity Direct Substitute): This part matches the core electrical specifications with ±0.1% tolerance and ±25ppm/°C temperature coefficient. The power rating is upgraded to 0.25W (1/4W), providing additional thermal margin. The seated height is 0.026" (0.65mm) compared to 0.024" (0.60mm) for the main part. TE Connectivity RP73P series maintains active production status and ROHS3 compliance. Selection is appropriate for applications where increased power dissipation capability is beneficial.

ERA-6AEB4122V (Panasonic Upgrade): This part provides ±0.1% tolerance and ±25ppm/°C temperature coefficient with AEC-Q200 automotive qualification. The package dimensions and power rating match the main part exactly. Panasonic ERA-6A series maintains active production status and ROHS3 compliance. Selection is appropriate for automotive applications or where AEC-Q200 certification is required.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0741K2L replace RT0805FRE0741K2L in any application?

A: Yes. RT0805BRD0741K2L is a direct upgrade with tighter tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C). Both parts share identical package dimensions, power rating, and operating temperature range. The improved specifications make it suitable for all applications where the original part is used.

Q: What is the difference between the 0.125W and 0.25W power ratings?

A: The 5-2176093-9 is rated for 0.25W (1/4W) power dissipation compared to 0.125W (1/8W) for the main part. This provides additional thermal margin and allows the component to dissipate more power without exceeding temperature limits. The 0.25W rating does not affect electrical performance in circuits designed for 0.125W operation.

Q: Are there height differences between substitute parts?

A: The 5-2176093-9 has a maximum seated height of 0.026" (0.65mm) compared to 0.024" (0.60mm) for RT0805FRE0741K2L, RT0805BRD0741K2L, and ERA-6AEB4122V. This 0.002" (0.05mm) difference is within typical PCB assembly tolerances but should be verified for applications with strict height constraints.

Q: When should ERA-6AEB4122V be selected over other substitutes?

A: ERA-6AEB4122V includes AEC-Q200 automotive qualification. Selection is appropriate for automotive applications, safety-critical systems, or designs requiring automotive-grade component certification. All other electrical and mechanical parameters are equivalent to RT0805BRD0741K2L.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed are available in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the significance of ±1% versus ±0.1% tolerance?

A: Tolerance defines the maximum deviation from the nominal resistance value. RT0805FRE0741K2L with ±1% tolerance allows resistance between 40.792 kOhms and 41.608 kOhms. Substitute parts with ±0.1% tolerance allow resistance between 41.1588 kOhms and 41.2412 kOhms. Tighter tolerance is beneficial for precision analog circuits, measurement applications, and feedback networks where resistance accuracy directly affects circuit performance.
