Engineering Selection Recommendations

The HPB200R5DA barometer sensor is a direct functional equivalent to the HPB100R5DA. Selection of the HPB200R5DA is supported by the following engineering factors:

Product Status Consideration: The HPB100R5DA is classified as obsolete, while the HPB200R5DA maintains active product status with Honeywell Aerospace. Active status ensures continued manufacturer support, documentation availability, and supply chain reliability.

Compliance Alignment: Both components share identical RoHS non-compliance status and moisture sensitivity classification, ensuring no regulatory or environmental handling changes are required during substitution.

Performance Enhancement: The HPB200R5DA provides improved accuracy specification (±0.006PSI versus ±0.012PSI), representing a 50% reduction in tolerance band. This enhanced accuracy is achievable without modification to system integration, power supply requirements, or communication protocols.

Interface Compatibility: Complete mechanical and electrical interface compatibility is maintained across all connection parameters, including port geometry, termination style, and RS-485 communication protocol.

For applications where the HPB100R5DA is currently specified, direct substitution with HPB200R5DA is supported without system redesign or recalibration.
