TARS-LCASS Equivalent & Substitute Parts Reference

Part Overview

The TARS-LCASS is a 6-axis inertial measurement unit (IMU) combining accelerometer and gyroscope functionality with CAN J1939 bus output, manufactured by Honeywell Sensing and Productivity Solutions. This motion sensor is designed for chassis-mounted applications requiring dual-axis acceleration and rotation measurement across an operating temperature range of -40°C to 85°C.

The TARS-LCASS has reached obsolete product status. Identifying equivalent substitute components is necessary to maintain system compatibility, ensure continued supply chain availability, and support ongoing production or maintenance requirements for applications currently utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TARS-LCASS is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Honeywell Sensing and Productivity Solutions (same manufacturer ensures design continuity)
• Series: TARS (same product family)
• Category: Motion Sensors (functional classification)
• Package / Case: Module (physical form factor)
• Mounting Type: Chassis Mount (installation compatibility)
• Operating Temperature Range: -40°C to 85°C (thermal envelope)
• Output Type: CAN Bus (communication protocol)

Substitution Logic: The TARS-LCASS specifies 6-axis sensor capability with CAN J1939 output. Substitute parts must maintain the same series designation, module packaging, chassis mount configuration, and operating temperature specifications. Output protocol compatibility (CAN bus variants) and RoHS compliance status are evaluated to ensure regulatory and system-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

TARS-BAASS as Primary Substitute:

The TARS-BAASS is the manufacturer-recommended substitute for the obsolete TARS-LCASS. Both components share identical operating temperature specifications (-40°C to 85°C), module packaging, chassis mount configuration, and CAN bus output protocol. Both are manufactured by Honeywell Sensing and Productivity Solutions within the TARS series.

Key Differentiation:

The TARS-BAASS operates as an active product with current manufacturing support, whereas the TARS-LCASS is obsolete. The TARS-BAASS provides ROHS3 compliance, representing a more current regulatory standard than the RoHS compliance of the TARS-LCASS. The TARS-BAASS specifies a moisture sensitivity level of 1 (Unlimited), indicating enhanced environmental tolerance.

Functional Consideration:

The TARS-BAASS provides 3-axis accelerometer and gyroscope measurement, whereas the TARS-LCASS provides 6-axis measurement. This represents a reduction in measurement dimensionality. Applications requiring full 6-axis data output must evaluate whether 3-axis measurement satisfies system requirements.

Supply Chain Status:

The TARS-BAASS maintains active inventory (852 pieces new original in stock) compared to the TARS-LCASS obsolete status, ensuring long-term component availability and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the TARS-BAASS directly replace the TARS-LCASS in existing applications?

A: The TARS-BAASS shares identical operating temperature range, module packaging, chassis mount configuration, and CAN bus output protocol with the TARS-LCASS. However, the TARS-BAASS provides 3-axis measurement capability versus the 6-axis capability of the TARS-LCASS. Direct replacement is possible only if the application requires 3-axis data or can operate with reduced measurement dimensionality.

Q: What is the difference between CAN J1939 and CAN bus output?

A: The TARS-LCASS specifies CAN J1939 output, which is a specific CAN protocol variant commonly used in heavy-duty vehicle and industrial applications. The TARS-BAASS specifies CAN bus output. Both are CAN-based communication protocols. Protocol compatibility must be verified at the system integration level.

Q: Are there inventory considerations for the TARS-BAASS?

A: The TARS-BAASS maintains 852 pieces of new original inventory in stock, providing immediate availability. The TARS-LCASS, being obsolete, has limited remaining inventory (914 pieces). For new designs or long-term production, the TARS-BAASS active status ensures sustained supply chain support.

Q: Does the TARS-BAASS meet the same regulatory requirements as the TARS-LCASS?

A: The TARS-LCASS is RoHS Compliant. The TARS-BAASS is ROHS3 Compliant, representing a more current regulatory standard. The TARS-BAASS also specifies REACH Unaffected status. Both components meet RoHS-level environmental compliance requirements, with the TARS-BAASS representing a more current compliance posture.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1 (Unlimited) on the TARS-BAASS?

A: MSL 1 (Unlimited) indicates that the TARS-BAASS has no moisture sensitivity restrictions and does not require controlled humidity storage or handling. The TARS-LCASS specifies MSL as Not Applicable, indicating no moisture sensitivity constraints. Both components are suitable for standard industrial storage and handling environments.

Q: Are both parts available in the same physical package?

A: Both the TARS-LCASS and TARS-BAASS are specified as Module package type with Chassis Mount mounting configuration. Physical form factor compatibility is confirmed, allowing mechanical interchangeability in chassis-mounted applications.
