HSCSRRD001PD2A3

Pressure Sensors Transducers Overview

The Honeywell HSCSRRD001PD2A3 is a differential piezoresistive pressure sensor from the TruStability® HSC series. It features a ±1 PSI (±6.89 kPa) working pressure range with a maximum overload capacity of ±10 PSI (±68.95 kPa). The device provides a digital I2C output with 12-bit resolution and ±0.25% accuracy. Powered by a 3V to 3.6V supply, it includes integrated signal amplification and temperature compensation. The component utilizes a 4-SIP package with PC pin termination for through-hole mounting.

Pressure Sensors Transducers Procurement Notes

Verify that the specific suffix A3 corresponds to the required I2C address configuration and port style specifications. Confirm that the 4-SIP package dimensions align with the target PCB footprint. Ensure the operating voltage range of 3V to 3.6V matches the system power supply rails. Check that the through-hole mounting method is compatible with the assembly process. Validate that the ±1 PSI range meets the application's dynamic pressure requirements.

Pressure Sensors Transducers Selection Notes

Select this model when a digital I2C output is preferred over analog signals to simplify microcontroller interfacing. Choose the 4-SIP package for robust through-hole mechanical stability in industrial environments. Consider the ±0.25% accuracy specification for applications demanding high precision in low-pressure differentials. Evaluate the -20°C to 85°C operating temperature range against environmental conditions. Compare the 12-bit resolution against system noise requirements to ensure adequate signal fidelity.

Pressure Sensors Transducers Part Context

This component belongs to the Honeywell TruStability® HSC family, which specializes in miniature, high-performance pressure sensors. The HSCSRRD base indicates a differential pressure sensor with specific port configurations. The series is engineered for compact designs where space constraints and electrical noise immunity are critical factors in sensor selection.

Pressure Sensors Transducers Replacement Considerations

HSCSNBN001PD4A3 offers similar differential pressure characteristics but features a different port size (0.19 inch vs 0.08 inch) and potentially different port styles. Verify mechanical compatibility before substitution. Other HSC series variants may share electrical parameters but differ in pressure ranges or package types.
