HSCMRRN001PD3A3

Pressure Sensors Transducers Overview

The HSCMRRN001PD3A3 is a discontinued differential pressure sensor from the Honeywell TruStability HSC series. It features an I2C digital output with 12-bit resolution and ±0.25% accuracy. The device operates on a 3V to 3.6V supply and supports a working pressure of ±1PSI (±6.89kPa) with a maximum pressure of ±10PSI (±68.95kPa). It utilizes dual radial barbed ports sized at 0.08 inches (1.93mm) and is housed in an 8-SMD, J-lead package for surface mount board installation. The unit includes amplified output and temperature compensation, functioning within a temperature range of -20°C to 85°C.

Pressure Sensors Transducers Procurement Notes

This component is officially discontinued and no longer supplied by DigiKey. Verification of availability requires checking secondary market distributors or authorized agents for remaining stock. Engineers must confirm the part status before initiating procurement processes, as standard ordering channels do not support this item. Cross-reference with equivalent active parts is recommended for new designs.

Pressure Sensors Transducers Selection Notes

Select this component only for legacy system maintenance or repair where specific form-factor compatibility is required. The 8-SMD J-lead package and dual-port configuration are unique physical constraints. For new developments, consider active equivalents within the TruStability family that offer identical electrical specifications but utilize currently supported packaging and manufacturing statuses.

Pressure Sensors Transducers Part Context

Part of the Honeywell TruStability HSC series, designed for low-pressure differential applications. This specific model represents a surface-mount variant with J-leads, distinguishing it from through-hole SIP versions like the HSCSRRD series. It integrates MEMS sensing elements with on-chip signal processing to deliver calibrated digital readings.

Pressure Sensors Transducers Replacement Considerations

HSCMRRN001PD2A3 is documented as a parameter-equivalent substitute. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement part meets the same I2C protocol and voltage requirements.
