Key Parameters

Substitute Part Grouping Explanation

Substitution of the KAI-0340-AAA-CF-AA-DUAL is determined by the following critical parameters:

• Sensor Type: CCD versus CMOS technology
• Active Pixel Array: Resolution matching or compatibility with system requirements
• Pixel Size: Optical characteristics affecting image quality and field of view
• Frame Rate: Temporal performance requirements
• Supply Voltage: Power delivery compatibility
• Package Configuration: Physical and electrical interface constraints
• Operating Temperature Range: Environmental operating conditions
• Product Status and Compliance: Availability and regulatory adherence

The identified substitute, NOIP1SN0480A-STI, represents a technology transition from CCD to CMOS architecture. While both sensors are manufactured by onsemi and maintain ROHS3 compliance, they differ in sensor type, pixel dimensions, resolution, frame rate, and supply voltage requirements. Substitution requires system-level evaluation of these parameter differences.

Parameter Comparison

Engineering Selection Recommendations

Selection between the KAI-0340-AAA-CF-AA-DUAL and NOIP1SN0480A-STI must account for the following factors:

Product Status: The KAI-0340-AAA-CF-AA-DUAL is obsolete, while NOIP1SN0480A-STI is active. For new designs or long-term production support, the active status of NOIP1SN0480A-STI provides supply chain continuity.

Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent regulatory requirements.

Technology Architecture: The transition from CCD to CMOS represents a fundamental sensor architecture change. CCD sensors and CMOS sensors operate on different principles and have distinct electrical interfaces, timing requirements, and signal characteristics.

Electrical Interface: Supply voltage differs significantly (14.75V–15.25V versus 1.8V and 3.3V), requiring redesign of power delivery circuits.

Optical Characteristics: Pixel size reduction from 7.4µm to 4.8µm and resolution increase from 640H x 480V to 808H x 608V alter optical performance and system integration requirements.

Performance Parameters: Frame rate reduction from 210 fps to 120 fps may impact temporal resolution in motion-critical applications.

Frequently Asked Questions (FAQ)

Q: Can NOIP1SN0480A-STI directly replace KAI-0340-AAA-CF-AA-DUAL in existing designs?

A: Direct replacement is not possible. The sensors differ in type (CCD versus CMOS), supply voltage, pixel size, resolution, and frame rate. System redesign is required, including signal processing circuits, power delivery, and timing control.

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

A: CCD and CMOS are distinct sensor architectures with different charge transfer mechanisms, signal readout methods, and electrical interfaces. They require different support circuitry and signal processing approaches.

Q: Does the higher resolution of NOIP1SN0480A-STI (808H x 608V) make it a direct upgrade?

A: Higher resolution does not constitute a direct upgrade. The smaller pixel size (4.8µm versus 7.4µm) affects optical performance, light sensitivity, and noise characteristics. System optical design must be re-evaluated.

Q: Are there package compatibility concerns?

A: Yes. The KAI-0340-AAA-CF-AA-DUAL uses a 22-CDIP module package, while NOIP1SN0480A-STI package information is not specified in the provided data. Physical and electrical interface compatibility must be verified.

Q: What is the impact of the lower frame rate in NOIP1SN0480A-STI?

A: Frame rate reduction from 210 fps to 120 fps affects temporal resolution. Applications requiring high-speed image capture may not be compatible with the lower frame rate.

Q: Are both components suitable for the same operating temperature range?

A: No. KAI-0340-AAA-CF-AA-DUAL operates from -50°C to 70°C, while NOIP1SN0480A-STI operates from -40°C to 85°C. Temperature range requirements must be evaluated for specific applications.

Q: What power supply modifications are needed for substitution?

A: KAI-0340-AAA-CF-AA-DUAL requires 14.75V to 15.25V, while NOIP1SN0480A-STI requires 1.8V and 3.3V. Complete power delivery circuit redesign is necessary.
