HG4930CS25 Equivalent & Substitute Parts

Part Overview

The HG4930CS25 is a 6-axis motion sensor manufactured by Honeywell Aerospace, integrating accelerometer and gyroscope functionality with RS-422 serial output. This component is classified as obsolete and is no longer in active production. Due to its obsolete status, sourcing original units becomes increasingly difficult. Identifying equivalent substitute parts ensures design continuity and maintains system performance in applications requiring 6-axis inertial measurement capabilities with RS-422 communication protocol.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HG4930CS25 are identified based on strict parameter matching across the following critical criteria:

Functional Equivalence Parameters:

• Sensor Type: Accelerometer and Gyroscope, 6-axis configuration
• Output Interface: RS-422 serial communication protocol
• Operating Temperature Range: -54°C to 85°C
• Mounting Configuration: Chassis Mount
• Package Form Factor: Module

Series Continuity:

• Base Product Number: HG4930 series designation

The HG4930CA51 qualifies as a substitute part because it maintains identical specifications across all functional and environmental parameters. Both components operate within the same temperature envelope, utilize identical RS-422 output protocol, and share the same 6-axis sensor architecture. The primary distinction lies in product status and packaging configuration.

Engineering Selection Recommendations

Primary Substitute: HG4930CA51

The HG4930CA51 is the direct functional equivalent for the obsolete HG4930CS25. Selection of this substitute is based on the following engineering criteria:

Functional Compatibility: Both components share identical sensor architecture (6-axis accelerometer/gyroscope), output protocol (RS-422), and environmental operating range (-54°C to 85°C). No signal conditioning or interface modifications are required for direct substitution.

Product Status Advantage: The HG4930CA51 maintains active production status with Honeywell Aerospace, ensuring long-term availability and supply chain reliability. Current inventory of 751 pieces supports immediate procurement requirements.

Compliance Alignment: Both components maintain identical RoHS non-compliance status, ensuring regulatory consistency within existing system designs. The HG4930CA51 includes REACH Unaffected designation and ECCN 7A994 classification.

Mechanical Compatibility: Chassis mount configuration and module form factor remain unchanged, permitting direct mechanical integration without enclosure or mounting structure modifications.

Frequently Asked Questions (FAQ)

Q: Can the HG4930CA51 replace the HG4930CS25 without design modifications?

A: Yes. The HG4930CA51 provides direct functional substitution. Identical sensor type, output protocol, temperature range, and mounting configuration eliminate the requirement for circuit design or mechanical changes. Direct pin-to-pin or connector-to-connector replacement is applicable.

Q: What is the primary difference between HG4930CS25 and HG4930CA51?

A: The HG4930CS25 is obsolete and no longer manufactured. The HG4930CA51 is the active production equivalent from the same HG4930 series. Both components are functionally identical across all electrical and mechanical parameters. Packaging configuration differs (unspecified versus bulk), but this does not affect component performance or integration.

Q: Are there RoHS compliance considerations for this substitution?

A: Both the HG4930CS25 and HG4930CA51 are RoHS non-compliant. If your application requires RoHS-compliant components, neither part satisfies this requirement. Substitution maintains existing compliance status without improvement or degradation.

Q: What is the operating temperature compatibility?

A: Both components operate across the identical temperature range of -54°C to 85°C. No thermal performance variation exists between the main part and substitute. System thermal design remains unchanged.

Q: Is the RS-422 output protocol identical between both parts?

A: Yes. Both the HG4930CS25 and HG4930CA51 utilize RS-422 serial communication protocol. Signal levels, timing, and protocol specifications are identical. No interface adapter or signal conditioning is required.

Q: What inventory status should influence my selection?

A: The HG4930CA51 has 751 pieces in current stock with active production status. The HG4930CS25 has 943 pieces in stock but is obsolete. For new designs or long-term production requirements, the HG4930CA51 is the appropriate selection due to sustained availability.
