Substitute Part Grouping Explanation

The ERA-8AEB6490V qualifies as a direct substitute for the RT1206FRE07649RL based on the following critical parameters:

• Resistance Value: Both parts are 649 Ohms
• Package Format: Both use 1206 (3216 Metric) surface mount package
• Power Rating: Both rated at 0.25W (1/4W)
• Composition: Both are thin film resistors
• Operating Temperature Range: Both support -55°C to 155°C
• Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited)
• Termination Count: Both have 2 terminations

The ERA-8AEB6490V represents an upgrade option with improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), while maintaining full mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07649RL and ERA-8AEB6490V are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for standard industrial and commercial applications. The ERA-8AEB6490V carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Selection between these parts should be based on application requirements: the RT1206FRE07649RL for general-purpose use, and the ERA-8AEB6490V for applications requiring tighter tolerance control, lower temperature coefficient drift, or automotive compliance.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB6490V directly replace the RT1206FRE07649RL in existing designs?

A: Yes. Both parts share identical resistance values, power ratings, package formats, and operating temperature ranges. The ERA-8AEB6490V is mechanically and electrically compatible as a direct substitute.

Q: What are the key differences between these two parts?

A: The ERA-8AEB6490V offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Additionally, the ERA-8AEB6490V carries AEC-Q200 automotive qualification, while the RT1206FRE07649RL does not specify automotive ratings.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variations exist. The RT1206FRE07649RL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with a maximum seated height of 0.026" (0.65mm). The ERA-8AEB6490V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with a maximum seated height of 0.028" (0.70mm). Both dimensions remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which part should be selected for high-precision applications?

A: The ERA-8AEB6490V is the appropriate choice for applications requiring tighter tolerance control and lower temperature coefficient performance.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. The ERA-8AEB6490V additionally meets AEC-Q200 automotive standards.
