Substitute Part Grouping Explanation

Substitution of the MLX90615SSG-DAG-000-SP is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Package Compatibility: Both the main part and substitute must utilize the TO-46-4 through-hole metal can package to ensure mechanical fit and thermal interface consistency.

Sensor Technology: The MLX90615SSG-DAG-000-SP employs digital infrared sensing with dual-channel temperature measurement (local and remote). Substitute parts must provide infrared temperature sensing capability to maintain functional equivalence.

Temperature Range Coverage: The main part covers local sensing from -40°C to 85°C and remote IR sensing to 115°C. Substitute parts must support overlapping or equivalent temperature ranges for the intended application.

Output Protocol: The MLX90615SSG-DAG-000-SP provides PWM and SMBus digital outputs. Substitute parts with different output types (such as analog voltage) represent functional alternatives rather than direct equivalents, requiring circuit-level design modifications.

Supply Voltage: The main part operates at 2.6V to 3.4V. Substitute parts must operate within compatible voltage ranges to ensure direct integration into existing power distribution networks.

Compliance and Certification: The MLX90615SSG-DAG-000-SP holds AEC-Q100 automotive qualification and ROHS3 compliance. Substitute parts should maintain equivalent or superior compliance status for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Limitations: The ZTP-135BS cannot serve as a direct pin-compatible replacement for the MLX90615SSG-DAG-000-SP due to fundamental differences in output architecture. The MLX90615SSG-DAG-000-SP provides digital outputs (PWM and SMBus), while the ZTP-135BS provides analog voltage output. This difference requires circuit-level modifications including signal conditioning and analog-to-digital conversion stages.

Package Compatibility: Both components utilize TO-46-4 through-hole metal can packages, ensuring mechanical fit within existing sensor mounting interfaces. The ZTP-135BS features a lens top variant, which may affect thermal coupling characteristics compared to the standard metal can of the MLX90615SSG-DAG-000-SP.

Temperature Range Considerations: The MLX90615SSG-DAG-000-SP supports extended low-temperature operation (-40°C local sensing) and high remote IR sensing (115°C). The ZTP-135BS operates from -20°C to 100°C for both local and remote sensing. Applications requiring operation below -20°C or remote sensing above 100°C cannot utilize the ZTP-135BS as a substitute.

Compliance Status: The MLX90615SSG-DAG-000-SP holds AEC-Q100 automotive qualification. The ZTP-135BS is listed as active with RoHS compliance but does not specify AEC-Q100 qualification. For automotive applications requiring AEC-Q100 certification, the ZTP-135BS may not meet regulatory requirements.

Product Availability: The MLX90615SSG-DAG-000-SP is obsolete with 1155 units in stock. The ZTP-135BS is active with 1461 units available, providing improved long-term supply chain continuity for new designs or redesigned systems.

Frequently Asked Questions (FAQ)

Q: Can the ZTP-135BS replace the MLX90615SSG-DAG-000-SP in an existing circuit without modifications?

A: No. The ZTP-135BS cannot serve as a direct replacement without circuit modifications. The MLX90615SSG-DAG-000-SP outputs digital signals (PWM and SMBus), while the ZTP-135BS provides analog voltage output. Any substitution requires redesign of signal processing and microcontroller interface stages.

Q: What are the key differences in temperature sensing capability between these two sensors?

A: The MLX90615SSG-DAG-000-SP measures local temperatures from -40°C to 85°C and remote IR temperatures from -40°C to 115°C. The ZTP-135BS measures temperatures from -20°C to 100°C for both local and remote sensing. Applications requiring operation below -20°C or remote sensing above 100°C must retain the MLX90615SSG-DAG-000-SP or identify alternative sensors.

Q: Are both sensors suitable for automotive applications?

A: The MLX90615SSG-DAG-000-SP is qualified to AEC-Q100 automotive standards. The ZTP-135BS does not specify AEC-Q100 qualification. For automotive applications requiring AEC-Q100 certification, the MLX90615SSG-DAG-000-SP is the appropriate choice. The ZTP-135BS may be suitable for non-automotive or less stringent applications.

Q: What is the significance of the TO-46-4 package difference between these sensors?

A: Both sensors use TO-46-4 through-hole metal can packages, ensuring mechanical compatibility with existing mounting interfaces. The ZTP-135BS features a lens top variant, which may alter thermal coupling and field-of-view characteristics compared to the standard metal can. Thermal performance should be validated for the specific application.

Q: Why is the MLX90615SSG-DAG-000-SP classified as obsolete?

A: The MLX90615SSG-DAG-000-SP is listed as obsolete by the manufacturer, indicating discontinued production. Despite obsolete status, 1155 units remain in stock. For long-term supply chain planning, alternative sensors with active production status should be evaluated for new designs.

Q: What supply voltage does the ZTP-135BS require?

A: The supply voltage specification for the ZTP-135BS is not provided in the available technical parameters. This information must be obtained from the manufacturer's datasheet before circuit integration to ensure compatibility with existing power distribution networks.
