Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07665KL is determined by the following mandatory parameters:

• Resistance value: 665 kOhms (exact match required)
• Power rating: 0.25W minimum
• Package: 1206 (3216 Metric) form factor
• Composition: Thin film technology
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS3 compliance status

The ERA-8AEB6653V qualifies as a direct substitute based on these criteria. Enhanced specifications such as improved tolerance (±0.1% vs ±1%) and automotive qualification (AEC-Q200) represent performance upgrades that do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07665KL and ERA-8AEB6653V maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity ratings. The ERA-8AEB6653V provides enhanced tolerance performance (±0.1% vs ±1%) and includes AEC-Q200 automotive qualification. Selection between these components should be based on application requirements for tolerance precision and automotive-grade reliability certification.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB6653V replace RT1206FRE07665KL in existing designs?

A: Yes. Both components share identical resistance value (665 kOhms), power rating (0.25W), package type (1206), and operating temperature range (-55°C to 155°C). Physical dimensions are within acceptable tolerance for PCB footprint compatibility.

Q: What are the dimensional differences between these parts?

A: RT1206FRE07665KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. ERA-8AEB6653V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. Both fit standard 1206 PCB pads.

Q: Does the improved tolerance of ERA-8AEB6653V affect circuit performance?

A: The ERA-8AEB6653V tolerance of ±0.1% is tighter than the RT1206FRE07665KL tolerance of ±1%. This represents improved accuracy and may benefit precision analog circuits, but does not create incompatibility with designs specified for ±1% tolerance.

Q: Are both components suitable for automotive applications?

A: The ERA-8AEB6653V carries AEC-Q200 automotive qualification. The RT1206FRE07665KL does not specify automotive qualification. For automotive designs, ERA-8AEB6653V is the appropriate selection.

Q: What is the significance of temperature coefficient differences?

A: RT1206FRE07665KL has ±50ppm/°C temperature coefficient while ERA-8AEB6653V has ±25ppm/°C. Lower temperature coefficient indicates better resistance stability across the operating temperature range, beneficial for precision applications.
