Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07243KL is determined by the following mandatory parameters:

• Resistance Value: Must be 243 kOhms
• Package Type: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Tolerance: ±1% or better (tighter tolerance is acceptable)
• Power Rating: Must be ≥0.125W (higher power rating is acceptable)
• RoHS Compliance: Must maintain ROHS3 Compliant status

All identified substitute parts meet these criteria. Tolerance improvements and temperature coefficient enhancements represent performance upgrades rather than functional deviations.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07243KL (YAGEO): Direct upgrade within the same manufacturer series. Offers improved tolerance (±0.1% vs ±1%) and superior temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package specifications. Recommended for applications requiring enhanced precision without changing supplier relationships.

3-2176094-0 (TE Connectivity): Functionally equivalent with enhanced power rating (0.25W vs 0.125W). Tolerance and temperature coefficient match RT0805BRD07243KL. Height specification increases marginally (0.026" vs 0.024"). Suitable for designs with higher thermal dissipation requirements or when TE Connectivity supply chain is preferred.

ERA-6AEB2433V (Panasonic): Upgrade option with automotive-grade AEC-Q200 qualification. Delivers ±0.1% tolerance and ±25ppm/°C temperature coefficient. Recommended for automotive applications, safety-critical systems, or designs requiring enhanced reliability certification. Highest inventory availability among substitutes.

All substitute parts maintain full RoHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07243KL replace RT0805FRE07243KL in existing designs?

A: Yes. Both components share identical resistance value, package type, power rating, and operating temperature range. The substitute offers improved tolerance (±0.1% vs ±1%) and temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade with no circuit modifications required.

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

A: The 3-2176094-0 is rated for twice the power dissipation (0.25W vs 0.125W). This allows operation in higher-current applications without thermal stress. The 0805 package dimensions remain identical. Use the higher-rated component only if circuit analysis confirms power dissipation exceeds 0.125W.

Q: Is ERA-6AEB2433V suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents an additional quality assurance layer and does not restrict use to automotive circuits. The component meets all standard industrial specifications and is suitable for general-purpose applications.

Q: Are there any height or footprint differences between these parts?

A: Maximum seated heights are 0.024" (RT0805FRE07243KL, RT0805BRD07243KL, ERA-6AEB2433V) and 0.026" (3-2176094-0). All components use identical 0805 package footprints. The 0.002" height variance for the TE Connectivity part is negligible for standard PCB assembly processes.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing environments and storage conditions.
