HSCMRRN001PDAA3 Equivalent & Substitute Parts

Part Overview

The HSCMRRN001PDAA3 is an active, board-mount pressure sensor from Honeywell's TruStability® HSC series. This differential pressure sensor operates within ±1PSI (±6.89kPa) range with analog voltage output (0.33V ~ 2.97V) and is designed for surface-mount applications requiring amplified, temperature-compensated measurements. The sensor features dual barbed ports on the same side with J-lead termination in an 8-SMD package configuration.

Identifying equivalent and substitute parts is necessary when addressing inventory constraints, supply chain disruptions, or when alternative output formats better suit system integration requirements while maintaining core pressure measurement specifications.

Frequently Asked Questions (FAQ)

Q: Can HSCMRRN001PDSA3 directly replace HSCMRRN001PDAA3 on an existing PCB?

A: Physical and mechanical replacement is possible due to identical package configuration (8-SMD, J-Lead, Dual Ports, Same Side) and port specifications. However, the output interface differs: HSCMRRN001PDAA3 outputs analog voltage (0.33V ~ 2.97V), while HSCMRRN001PDSA3 outputs 12-bit SPI digital data. Circuit-level modifications are required to accommodate the different signal formats. Verify that your system's signal conditioning and data acquisition stages support SPI protocol before substitution.

Q: Are the pressure measurement specifications identical between these parts?

A: Yes. Both parts operate within ±1PSI (±6.89kPa) differential pressure range with ±0.25% accuracy, ±10PSI maximum pressure rating, and identical supply voltage requirements (3V ~ 3.6V). Pressure measurement performance is equivalent.

Q: What is the significance of the different RoHS certifications?

A: HSCMRRN001PDAA3 carries RoHS Compliant certification, while HSCMRRN001PDSA3 carries ROHS3 Compliant certification. Both meet their respective regulatory requirements. ROHS3 represents a more recent compliance framework. Selection should align with your product's regulatory requirements and target market specifications.

Q: Are both parts suitable for new product designs?

A: Yes. Both parts maintain Active product status within Honeywell's TruStability® HSC series and are appropriate for new designs, production applications, and ongoing inventory management.
