Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDX030G24R-DO requires evaluation based on the following critical parameters that define functional equivalence within the ASDX series:

Pressure Rating Compatibility: The substitute must operate within the same pressure measurement range or provide equivalent full-scale deflection capability for the application.

Output Interface: The ASDX030G24R-DO provides I2C digital output at 12-bit resolution. Substitutes with different output types (analog voltage, different digital protocols) represent functional alternatives rather than direct equivalents.

Supply Voltage: Both parts operate within the 4.75V ~ 5.25V range, ensuring power supply compatibility.

Mechanical Interface: Port size (0.09" male barbless tube), package type (8-DIP through-hole), and mounting configuration must align with PCB design constraints.

Environmental Specifications: Operating temperature range (-20°C ~ 105°C) and accuracy (±2%) are consistent across ASDX series variants.

Compliance: RoHS compliance and product status determine long-term availability and regulatory suitability.

The ASDXRRX001PGAA5 is identified as a substitute within the ASDX series but operates at a different pressure rating (1PSI versus 30PSI) and provides analog voltage output rather than I2C digital output, making it a functional alternative for applications with different pressure measurement requirements and interface specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ASDX030G24R-DO is classified as obsolete. The ASDXRRX001PGAA5 maintains active product status with Honeywell, ensuring continued availability, technical support, and supply chain reliability for new designs or production continuations.

Compliance and Certification: Both parts maintain RoHS compliance and carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, satisfying regulatory requirements for equivalent substitution in compliant applications.

Functional Equivalence Limitations: Direct substitution of the ASDXRRX001PGAA5 for the ASDX030G24R-DO is limited by significant differences in pressure rating (1PSI versus 30PSI) and output interface (analog voltage versus I2C digital). Selection of the substitute requires application-level compatibility verification for pressure measurement range and signal processing architecture.

Inventory and Lead Time: The ASDXRRX001PGAA5 demonstrates higher inventory availability (2580 Pcs) compared to the obsolete main part (858 Pcs), supporting procurement continuity for ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the ASDXRRX001PGAA5 directly replace the ASDX030G24R-DO in existing designs?

A: Direct replacement is not recommended without design modification. The substitute operates at 1PSI full-scale pressure versus 30PSI for the main part, resulting in different measurement sensitivity and resolution. Additionally, the analog voltage output (0.5V ~ 4.5V) differs from the I2C digital output, requiring signal conditioning and firmware changes in the host system.

Q: What are the key compatibility factors for ASDX series pressure sensor substitution?

A: Critical compatibility factors include: operating pressure range, output interface type and specification, supply voltage requirements, port size and style, package footprint, and operating temperature range. All parameters must align with application requirements and PCB design constraints.

Q: Are both parts suitable for the same mechanical mounting configuration?

A: Both parts use 8-DIP through-hole packaging with 0.09" male barbless tube ports, supporting identical PCB mounting. However, the ASDXRRX001PGAA5 features a dual port configuration, which may require mechanical accommodation in the application.

Q: What is the significance of the obsolete product status for the ASDX030G24R-DO?

A: Obsolete status indicates that Honeywell has discontinued production and support for this part. Existing inventory may be limited, and long-term availability cannot be assured. Active alternatives such as the ASDXRRX001PGAA5 provide supply chain continuity and ongoing manufacturer support.

Q: Do both sensors provide equivalent accuracy specifications?

A: Both parts specify ±2% accuracy and operate within identical temperature ranges (-20°C ~ 105°C) with temperature compensation. Accuracy equivalence is maintained across the ASDX series, though absolute measurement error scales with the full-scale pressure rating of each sensor.

Q: What output interface differences exist between these sensors?

A: The ASDX030G24R-DO provides I2C digital output at 12-bit resolution, enabling direct digital communication with microcontroller I2C interfaces. The ASDXRRX001PGAA5 provides analog voltage output (0.5V ~ 4.5V), requiring analog-to-digital conversion in the host system. These interfaces are not interchangeable without signal conditioning modifications.
