Key Parameters

Substitute Part Grouping Explanation

Substitution of the KAI-08051-AXA-JP-BA is determined by the following critical parameters:

• Sensor Technology: CCD versus CMOS architecture affects signal processing and integration requirements
• Active Pixel Array: Resolution in horizontal and vertical dimensions (3296H x 2472V)
• Pixel Size: Physical dimensions of individual photosensitive elements (5.5µm x 5.5µm)
• Frames per Second: Data throughput capability (16 fps)
• Supply Voltage: Operating voltage range (14.5V ~ 15.5V)
• Package Type: Physical form factor and pin configuration (68-BPGA)
• Operating Temperature Range: Thermal operating limits (-50°C ~ 70°C)
• Product Status and Compliance: RoHS3 compliance and availability status

The identified substitute part NOIX1SN8000B-LTI represents a technology transition from CCD to CMOS architecture while maintaining optical sensor functionality within the onsemi product family.

Parameter Comparison

Engineering Selection Recommendations

The NOIX1SN8000B-LTI is listed as an active product with current manufacturing status, whereas the KAI-08051-AXA-JP-BA is obsolete. Both components maintain ROHS3 compliance and are manufactured by onsemi, ensuring regulatory alignment.

Selection of NOIX1SN8000B-LTI as a substitute requires evaluation of the following design-level differences:

• Sensor Architecture: Transition from interline CCD to CMOS technology introduces different signal characteristics and integration methodologies
• Pixel Array and Resolution: Horizontal resolution increases from 3296 to 4096 pixels; vertical resolution decreases from 2472 to 2160 pixels
• Pixel Pitch: Reduction from 5.5µm to 3.2µm affects optical system design and light collection efficiency
• Frame Rate: Increase from 16 fps to 128 fps provides enhanced temporal resolution
• Supply Voltage: Significant reduction from 14.5V–15.5V to 1.7V–1.9V and 2.7V–2.9V requires power supply redesign
• Package Footprint: Change from 68-BPGA (40x29) to 163-BCLGA (20.88x19.9) affects PCB layout and mechanical integration
• Operating Temperature: Upper limit extends from 70°C to 85°C; lower limit increases from -50°C to -40°C

Frequently Asked Questions (FAQ)

Q: Can NOIX1SN8000B-LTI directly replace KAI-08051-AXA-JP-BA without design modifications?

A: No. The substitute part requires design-level changes including power supply reconfiguration, PCB layout revision due to different package geometry, and optical system adjustment for the reduced pixel pitch. Signal processing firmware may require adaptation for CMOS versus CCD operation.

Q: What are the key differences between CCD and CMOS sensor types?

A: CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor) represent different image sensor architectures. CCD sensors use sequential charge transfer for signal readout, while CMOS sensors employ per-pixel amplification. These architectural differences affect power consumption, noise characteristics, and integration requirements.

Q: How does the pixel size reduction from 5.5µm to 3.2µm impact optical design?

A: Smaller pixel pitch requires optical system redesign to maintain proper light collection and focus characteristics. Lens specifications, aperture settings, and sensor-to-lens distance may require adjustment to achieve equivalent optical performance.

Q: Are there compatibility concerns with the package change from 68-BPGA to 163-BCLGA?

A: Yes. The package change requires PCB layout redesign, including trace routing, via placement, and mechanical mounting modifications. Pin count and arrangement differ between the two packages.

Q: What is the impact of the supply voltage reduction from 14.5V–15.5V to 1.7V–1.9V and 2.7V–2.9V?

A: The substitute part requires a completely different power supply architecture. Existing 14.5V–15.5V power delivery systems cannot be used directly. New voltage regulation and power distribution design is necessary.

Q: Does the increased frame rate of 128 fps versus 16 fps affect system integration?

A: Yes. Higher frame rates increase data throughput requirements, necessitating evaluation of interface bandwidth, data storage capacity, and processing pipeline capability to handle the increased data volume.

Q: Are both parts compliant with current regulatory standards?

A: Both KAI-08051-AXA-JP-BA and NOIX1SN8000B-LTI maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.
