Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original RT0805FRE0712K4L specification.

RT0805BRD0712K4L and ERA-6AEB1242V offer improved tolerance performance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C), making them suitable for applications requiring enhanced precision and thermal stability.

RT0805DRE0712K4L provides intermediate tolerance improvement (±0.5%) while maintaining the original temperature coefficient specification, offering a balanced upgrade path.

1-2176093-3 from TE Connectivity Passive Product delivers higher power dissipation capability (0.25W versus 0.125W) alongside improved tolerance and temperature coefficient performance. This part is suitable for applications requiring increased thermal headroom within the 0805 package footprint.

ERA-6AEB1242V from Panasonic Electronic Components includes automotive AEC-Q200 qualification, making it the appropriate selection for automotive and high-reliability applications requiring formal qualification documentation.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0712K4L replace RT0805FRE0712K4L in any application?

A: Yes. RT0805BRD0712K4L is a direct substitute with identical resistance, package, power rating, and operating temperature range. The tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) represent performance improvements compatible with all applications designed for the original part.

Q: What is the difference between RT0805DRE0712K4L and RT0805BRD0712K4L?

A: Both parts share identical resistance, package, power rating, and operating temperature. RT0805BRD0712K4L offers tighter tolerance (±0.1% versus ±0.5%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Selection depends on application precision requirements.

Q: Why would 1-2176093-3 be selected over other substitutes?

A: 1-2176093-3 provides higher power rating (0.25W versus 0.125W) while maintaining the 0805 package footprint. This is beneficial for applications where thermal margin is critical or where component stress must be minimized. The improved tolerance and temperature coefficient are additional advantages.

Q: Is ERA-6AEB1242V suitable for non-automotive applications?

A: Yes. ERA-6AEB1242V meets all electrical and mechanical requirements for the RT0805FRE0712K4L. The automotive AEC-Q200 qualification represents an additional certification that does not restrict use in non-automotive applications. The part is fully compatible with standard industrial and consumer applications.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original RT0805FRE0712K4L packaging specification. Physical dimensions and termination count are identical across all parts.

Q: What is the impact of temperature coefficient differences on circuit performance?

A: Temperature coefficient defines resistance change per degree Celsius. The original RT0805FRE0712K4L exhibits ±50ppm/°C change, while substitute parts with ±25ppm/°C offer improved stability across temperature extremes. For a 12.4 kOhm resistor over a 100°C temperature swing, this represents a maximum variation difference of approximately 0.062% between the two specifications.
