Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07243KL is determined by the following critical parameters:

• Resistance Value: Must be 243 kOhms
• Package Format: Must be 1206 (3216 Metric) with compatible footprint dimensions
• Power Rating: Must be 0.25W (1/4W) or higher
• Operating Temperature Range: Must encompass -55°C ~ 155°C
• Composition: Thin film construction
• Termination Count: 2 terminations

Identified substitute parts maintain these core specifications while offering enhanced tolerance grades or automotive-grade certifications. All substitutes are thin film resistors in identical package format with equivalent or superior electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRE07243KL (YAGEO): This upgrade substitute offers improved tolerance specification (±0.5% versus ±1%) while maintaining identical package dimensions, power rating, and operating temperature range. Both YAGEO parts share the same thermal coefficient and RoHS3 compliance. Selection is appropriate for applications requiring tighter resistance tolerance without additional certification requirements.

ERA-8AEB2433V (Panasonic): This substitute provides the highest tolerance grade (±0.1%) and superior temperature coefficient performance (±25ppm/°C versus ±50ppm/°C). The part carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and qualification for automotive applications. Physical dimensions are within acceptable tolerance (3.20mm L × 1.60mm W versus 3.10mm × 1.60mm). Selection is appropriate for automotive applications or systems requiring precision resistor performance with automotive-grade reliability assurance.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRE07243KL directly replace RT1206FRE07243KL on existing PCBs?

A: Yes. Both parts share identical 1206 (3216 Metric) package footprints, termination configuration, and mounting requirements. The improved ±0.5% tolerance of the RT1206DRE07243KL is a direct upgrade with no PCB layout modifications required.

Q: Is ERA-8AEB2433V compatible with the same PCB footprint?

A: Yes. The ERA-8AEB2433V maintains the 1206 (3216 Metric) package format with compatible footprint dimensions. Physical dimensions (3.20mm L × 1.60mm W) are within standard PCB design tolerances for 1206 components. No layout changes are necessary.

Q: What is the significance of the AEC-Q200 rating on ERA-8AEB2433V?

A: AEC-Q200 is an automotive industry qualification standard indicating the component has undergone enhanced reliability testing and screening. This certification is relevant for automotive applications or systems requiring automotive-grade component reliability assurance.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE07243KL, RT1206DRE07243KL, and ERA-8AEB2433V are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the practical difference between ±1%, ±0.5%, and ±0.1% tolerance?

A: Tolerance specifies the maximum allowable deviation from the nominal 243 kOhms resistance value. ±1% allows ±2.43 kOhms deviation; ±0.5% allows ±1.215 kOhms deviation; ±0.1% allows ±0.243 kOhms deviation. Tighter tolerance grades are appropriate for precision analog circuits, measurement instrumentation, or applications with strict impedance matching requirements.

Q: Do all three parts operate across the same temperature range?

A: Yes. All three parts operate from -55°C to 155°C. However, ERA-8AEB2433V exhibits superior temperature stability with ±25ppm/°C coefficient compared to ±50ppm/°C for both YAGEO parts, resulting in lower resistance drift across temperature extremes.
