Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07649KL is determined by the following critical parameters:

• Resistance value must be 649 kOhms
• Package must be 1206 (3216 Metric) surface mount
• Power rating must be 0.25W minimum
• Composition must be thin film
• Operating temperature range must encompass -55°C to 155°C
• RoHS3 compliance required
• Tolerance may be equal to or tighter than ±1%
• Temperature coefficient may be equal to or lower than ±50ppm/°C

The ERA-8AEB6493V qualifies as a direct substitute based on matching all critical parameters while offering improved tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB6493V from Panasonic Electronic Components is a qualified substitute for the RT1206FRE07649KL. Both components maintain Active product status and full RoHS3 compliance. The ERA-8AEB6493V provides enhanced specifications with ±0.1% tolerance versus ±1%, and a lower temperature coefficient of ±25ppm/°C compared to ±50ppm/°C. The ERA-8AEB6493V carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. Physical dimensions are compatible within standard PCB assembly tolerances (length 3.20mm versus 3.10mm, height 0.70mm versus 0.65mm).

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB6493V be used as a direct replacement for RT1206FRE07649KL?

A: Yes. Both components share identical resistance value (649 kOhms), power rating (0.25W), package type (1206), composition (thin film), and operating temperature range (-55°C to 155°C). The ERA-8AEB6493V meets or exceeds all electrical specifications of the RT1206FRE07649KL.

Q: What are the physical dimension differences?

A: RT1206FRE07649KL dimensions are 3.10mm L × 1.60mm W × 0.65mm H (max). ERA-8AEB6493V dimensions are 3.20mm L × 1.60mm W × 0.70mm H (max). These differences fall within standard PCB assembly and land pattern tolerances for 1206 packages.

Q: Does tolerance difference affect circuit performance?

A: The ERA-8AEB6493V offers tighter tolerance (±0.1% versus ±1%), which reduces resistor value variation. This is an improvement for precision applications but does not prevent substitution in circuits designed for ±1% tolerance.

Q: Are both components RoHS compliant?

A: Yes. Both RT1206FRE07649KL and ERA-8AEB6493V are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the significance of AEC-Q200 qualification on the ERA-8AEB6493V?

A: AEC-Q200 is an automotive industry qualification standard. The ERA-8AEB6493V meets automotive reliability requirements, making it suitable for automotive and high-reliability applications. The RT1206FRE07649KL does not carry this designation.
