Key Parameters

Substitute Part Grouping Explanation

Substitution of the MLX90615SSG-DAA-000-SP is determined by the following critical parameters:

Mechanical Compatibility: Package type (TO-46-4), mounting method (Through Hole), and physical form factor must match to ensure direct replacement without circuit board redesign.

Functional Capability: The substitute must provide infrared temperature sensing with comparable local and remote temperature measurement ranges. The MLX90615SSG-DAA-000-SP operates with local sensing from -40°C to 85°C and remote IR sensing to 115°C.

Electrical Interface: Output type, supply voltage range, and communication protocol determine system integration feasibility. The MLX90615SSG-DAA-000-SP uses PWM and SMBus outputs with 2.6V to 3.4V supply voltage.

Performance Specifications: Resolution (15 bit) and accuracy (±0.5°C in nominal range, ±3°C in extended range) establish measurement precision requirements.

Compliance and Status: RoHS compliance, automotive grade qualification (AEC-Q100), and product availability status affect suitability for regulated applications and long-term supply assurance.

The identified substitute ZTP-148SRC1 shares the TO-46-4 package, through-hole mounting, infrared sensing capability, and RoHS compliance, though with differing output type and temperature range specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MLX90615SSG-DAA-000-SP is classified as obsolete. The ZTP-148SRC1 maintains active product status with 94,377 units in stock, providing supply continuity and manufacturer support.

Compliance Alignment: Both components meet RoHS compliance requirements. The MLX90615SSG-DAA-000-SP carries automotive-grade qualification (AEC-Q100), while the ZTP-148SRC1 compliance status is limited to RoHS designation. Applications requiring automotive-grade certification must evaluate whether the ZTP-148SRC1 meets specific qualification requirements.

Package and Mounting: Both components utilize TO-46-4 through-hole packages, enabling mechanical compatibility without board redesign. The ZTP-148SRC1 features a lens top variant, which may affect optical performance characteristics in specific applications.

Output Interface Differences: The MLX90615SSG-DAA-000-SP provides digital output (PWM, SMBus), while the ZTP-148SRC1 delivers analog voltage output. System integration requires corresponding changes to signal conditioning and microcontroller interface logic.

Temperature Range Differences: The ZTP-148SRC1 extends the local operating range to 100°C compared to the MLX90615SSG-DAA-000-SP's 85°C maximum. However, remote IR sensing specifications are not provided for the ZTP-148SRC1, limiting direct functional equivalence for dual-sensor applications.

Frequently Asked Questions (FAQ)

Q: Can the ZTP-148SRC1 directly replace the MLX90615SSG-DAA-000-SP without circuit modifications?

A: No. While both components share the TO-46-4 through-hole package, the ZTP-148SRC1 outputs analog voltage whereas the MLX90615SSG-DAA-000-SP outputs PWM and SMBus digital signals. Signal conditioning and microcontroller interface logic must be redesigned.

Q: What are the key mechanical compatibility factors?

A: Both components use TO-46-4 metal can packages with through-hole mounting. The ZTP-148SRC1 includes a lens top variant. Physical dimensions and pin configurations must be verified against specific board layouts.

Q: Does the ZTP-148SRC1 support remote infrared temperature measurement?

A: Remote IR sensing specifications are not provided for the ZTP-148SRC1. The MLX90615SSG-DAA-000-SP explicitly supports remote IR sensing to 115°C. Applications requiring dual-sensor capability must confirm ZTP-148SRC1 remote sensing capability through manufacturer documentation.

Q: Are both components suitable for automotive applications?

A: The MLX90615SSG-DAA-000-SP carries AEC-Q100 automotive-grade qualification. The ZTP-148SRC1 is designated RoHS compliant but lacks specified automotive qualification. Automotive applications must verify whether the ZTP-148SRC1 meets required qualification standards.

Q: What supply voltage does the ZTP-148SRC1 require?

A: Supply voltage specifications are not provided for the ZTP-148SRC1. The MLX90615SSG-DAA-000-SP operates at 2.6V to 3.4V. Voltage compatibility must be confirmed through manufacturer datasheets before implementation.

Q: How do the temperature sensing ranges compare?

A: The MLX90615SSG-DAA-000-SP provides local sensing from -40°C to 85°C with remote IR sensing to 115°C. The ZTP-148SRC1 provides local sensing from -20°C to 100°C. The ZTP-148SRC1 extends the upper local temperature limit but does not reach the lower temperature extreme of the MLX90615SSG-DAA-000-SP.

Q: What is the inventory status for each component?

A: The MLX90615SSG-DAA-000-SP is obsolete with 1,025 units in stock. The ZTP-148SRC1 is active with 94,377 units in stock, providing superior long-term supply assurance.
