Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07309RL is determined by the following critical parameters:

• Resistance Value: Must be 309 Ohms
• Package Format: Must be 1206 (3216 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Thin film technology maintains performance characteristics
• Operating Temperature Range: Must cover or exceed -55°C ~ 155°C
• Compliance: RoHS3 compliance and MSL Level 1 rating required for standard applications

The ERA-8AEB3090V qualifies as a direct substitute because it matches all critical parameters while offering enhanced tolerance (±0.1% versus ±1%) and automotive-grade certification (AEC-Q200). The improved tolerance and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) make this an upgrade option for precision-critical applications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB3090V serves as a direct substitute for the RT1206FRE07309RL in all standard applications. Both parts are actively produced, RoHS3 compliant, and rated for identical operating temperature ranges and power dissipation.

Selection between these parts should be based on application requirements:

• RT1206FRE07309RL: Suitable for general-purpose applications where ±1% tolerance is acceptable and cost optimization is a priority.
• ERA-8AEB3090V: Recommended for precision circuits, automotive applications, or designs requiring tighter tolerance control (±0.1%) and lower temperature coefficient drift (±25ppm/°C). The AEC-Q200 automotive qualification provides additional reliability assurance for mission-critical systems.

Both parts maintain identical physical dimensions and electrical performance within their specified tolerances, ensuring drop-in compatibility at the PCB level.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3090V be used as a direct replacement for RT1206FRE07309RL?

A: Yes. Both parts share identical resistance values (309 Ohms), power ratings (0.25W), package formats (1206), and operating temperature ranges (-55°C ~ 155°C). The ERA-8AEB3090V offers improved tolerance and temperature stability, making it a compatible upgrade.

Q: What are the physical dimension differences between these parts?

A: The RT1206FRE07309RL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with a maximum seated height of 0.026" (0.65mm). The ERA-8AEB3090V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with a maximum seated height of 0.028" (0.70mm). These minor variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Why does ERA-8AEB3090V have a lower temperature coefficient?

A: The ERA-8AEB3090V employs automotive-grade thin film technology with tighter manufacturing controls, resulting in a temperature coefficient of ±25ppm/°C compared to ±50ppm/°C for the RT1206FRE07309RL. This provides superior stability across the full operating temperature range.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RT1206FRE07309RL and ERA-8AEB3090V are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting standard environmental and regulatory requirements.

Q: Which part should I select for automotive applications?

A: The ERA-8AEB3090V is the appropriate choice for automotive applications due to its AEC-Q200 certification, which ensures compliance with automotive reliability and quality standards. The RT1206FRE07309RL is suitable for general-purpose applications without automotive requirements.
