Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0791KL is determined by the following criteria:

• Resistance Value: Must be 91 kOhms
• Package / Case: Must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Power Rating: Must be ≥0.25W (1/4W)
• Composition: Thin film construction
• Operating Temperature Range: Must cover or exceed -55°C ~ 155°C
• Compliance: RoHS3 compliance required; MSL rating of 1 or equivalent

The ERA-8AEB913V qualifies as a direct substitute based on matching resistance value, package type, power rating, composition, operating temperature range, and regulatory compliance. Enhanced specifications (±0.1% tolerance, ±25ppm/°C temperature coefficient, AEC-Q200 automotive qualification) represent performance upgrades that maintain full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

RT1206FRE0791KL (YAGEO): Select for general-purpose applications where standard ±1% tolerance and ±50ppm/°C temperature coefficient meet circuit requirements. Active product status ensures continued availability. ROHS3 compliance and MSL-1 rating support standard manufacturing and storage conditions.

ERA-8AEB913V (Panasonic): Select when enhanced precision (±0.1% tolerance) and improved temperature stability (±25ppm/°C) are required. AEC-Q200 automotive qualification provides additional reliability assurance for demanding environments. Identical package, power rating, and operating temperature range ensure direct mechanical and electrical substitution. ROHS3 compliance and MSL-1 rating maintain compatibility with standard assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB913V replace RT1206FRE0791KL in existing designs?

A: Yes. Both components share identical resistance value (91 kOhms), package type (1206), power rating (0.25W), composition (thin film), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB913V offers tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), representing performance improvements with no compatibility issues.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both components use the 1206 (3216 Metric) package with identical termination count (2). Dimensional variations (RT1206FRE0791KL: 3.10mm × 1.60mm × 0.65mm max height; ERA-8AEB913V: 3.20mm × 1.60mm × 0.70mm max height) are within standard PCB layout tolerances and do not affect placement or soldering.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. Moisture sensitivity level is 1 (unlimited) for both, indicating no special storage or handling requirements beyond standard manufacturing practices.

Q: When should ERA-8AEB913V be preferred over RT1206FRE0791KL?

A: Select ERA-8AEB913V for applications requiring precision analog circuits, high-stability reference networks, or automotive-grade reliability (AEC-Q200 qualification). The ±0.1% tolerance and ±25ppm/°C temperature coefficient reduce circuit drift and improve long-term performance stability.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components operate across -55°C ~ 155°C, supporting industrial and automotive temperature ranges. ERA-8AEB913V's lower temperature coefficient (±25ppm/°C) provides superior performance stability across this range compared to RT1206FRE0791KL (±50ppm/°C).
