Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT1206FRE07309KL is determined by the following critical parameters:

• Resistance Value: Must be 309 kOhms
• Package Type: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be 0.25W minimum
• Composition: Thin film technology for stability
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Compliance: RoHS3 and REACH compliance required

The ERA-8AEB3093V qualifies as a direct substitute based on matching all critical parameters. Enhanced specifications (±0.1% tolerance, ±25ppm/°C temperature coefficient, AEC-Q200 automotive qualification) represent performance upgrades while maintaining full compatibility with the original part's electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB3093V is a qualified substitute for the RT1206FRE07309KL in applications where the original part is unavailable or where enhanced performance specifications are required. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

The ERA-8AEB3093V offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for precision applications. The part carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications where the original part may not be specified.

Dimensional differences are minimal (length 3.20mm versus 3.10mm, height 0.70mm versus 0.65mm) and remain within standard 1206 package tolerances. Both parts are thin film resistors with identical power ratings and operating temperature ranges, ensuring functional equivalence in circuit design.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3093V replace RT1206FRE07309KL in any application?

A: Yes, the ERA-8AEB3093V is electrically and mechanically compatible with the RT1206FRE07309KL. Both parts share identical resistance value, power rating, package type, and operating temperature range. The substitute offers improved tolerance and temperature coefficient specifications.

Q: Are there any dimensional compatibility concerns?

A: Dimensional differences are within standard 1206 package tolerances. The ERA-8AEB3093V is 0.1mm longer and 0.05mm taller than the RT1206FRE07309KL. These variations do not affect PCB footprint compatibility or assembly processes for standard 1206 applications.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard. The ERA-8AEB3093V meets automotive-grade reliability requirements. This qualification is not present on the RT1206FRE07309KL but does not prevent use of the substitute in non-automotive applications.

Q: Do both parts require identical handling and storage conditions?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to both components.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For general-purpose applications, either part is suitable. For precision circuits requiring tighter tolerance control, the ERA-8AEB3093V (±0.1%) is preferred. For automotive applications, the ERA-8AEB3093V is the appropriate choice due to AEC-Q200 qualification.
