Parameter Comparison

Engineering Selection Recommendations

RT1206DRE0718K2L (YAGEO): This part provides tighter tolerance (±0.5%) compared to the original RT1206FRE0718K2L (±1%) while maintaining identical power rating, package, and operating temperature specifications. Both parts share YAGEO manufacturing and ROHS3 compliance. Selection is appropriate for applications requiring improved resistance accuracy without automotive qualification requirements.

ERA-8AEB1822V (Panasonic Electronic Components): This part offers the tightest tolerance (±0.1%) and lowest temperature coefficient (±25ppm/°C) among the three options. It carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. Physical dimensions are within standard 1206 package tolerance. Selection is appropriate for precision circuits and automotive-grade designs where enhanced stability and certification are required.

All three parts maintain identical 0.25W power rating, 1206 package footprint, and -55°C to 155°C operating range, ensuring direct functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRE0718K2L replace RT1206FRE0718K2L in any application?

A: Yes. RT1206DRE0718K2L is a direct substitute with improved tolerance (±0.5% vs ±1%). It maintains identical power rating (0.25W), package (1206), operating temperature range (-55°C ~ 155°C), and composition (thin film). The tighter tolerance makes it suitable for all applications where the original part is used.

Q: What is the primary difference between RT1206DRE0718K2L and ERA-8AEB1822V?

A: Both parts provide tighter tolerance than the original. ERA-8AEB1822V offers superior tolerance (±0.1% vs ±0.5%), lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), and AEC-Q200 automotive certification. RT1206DRE0718K2L is a standard industrial-grade part. Selection depends on application precision requirements and automotive qualification needs.

Q: Are there physical footprint differences between these parts?

A: All three parts use the 1206 (3216 Metric) package. ERA-8AEB1822V has slightly larger dimensions (0.126" L x 0.063" W vs 0.122" L x 0.063" W) and height (0.028" vs 0.026"), but these remain within standard 1206 package tolerance and are compatible with standard 1206 PCB footprints.

Q: Which part should be selected for automotive applications?

A: ERA-8AEB1822V is the appropriate choice for automotive applications due to AEC-Q200 qualification. It also provides the best tolerance (±0.1%) and temperature stability (±25ppm/°C) among the three options.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts—RT1206FRE0718K2L, RT1206DRE0718K2L, and ERA-8AEB1822V—are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).
