ASDX030A24R-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX030A24R-DO is a 30PSI absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component features 12-bit I2C digital output, temperature compensation, and through-hole mounting in an 8-DIP package with a 0.09" male tube port. The product is currently classified as obsolete, necessitating identification of active equivalent alternatives for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASDX030A24R-DO is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pressure Type: Absolute (required match)
• Operating Pressure: 30PSI (206.84kPa) (required match)
• Output Type: I2C digital interface (required match)
• Output Resolution: 12-bit (required match)
• Supply Voltage: 4.75V ~ 5.25V (required match)
• Accuracy: ±2% (required match)
• Operating Temperature Range: -20°C ~ 105°C (required match)
• Mounting Type: Through Hole (required match)
• Port Style: Barbless (required match)
• Temperature Compensation: Required feature

Secondary Compatibility Criteria:

• Port Size: 0.09" male tube (minor tolerance variation acceptable: 2.29mm to 2.31mm)
• Package Form: 8-DIP module configuration
• RoHS Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

Substitutes are classified into two categories:

Direct Substitutes: Parts meeting all primary and secondary compatibility criteria with active product status.

Similar Parts: Components sharing the ASDX series platform and core electrical specifications but differing in pressure type, output interface, or pressure range. These require application-level verification before implementation.

Engineering Selection Recommendations

ASDXACX030PA7A5 (Direct Substitute - Recommended)

The ASDXACX030PA7A5 is the primary equivalent for the obsolete ASDX030A24R-DO. This part maintains identical electrical specifications across all critical parameters: 30PSI absolute pressure measurement, 12-bit I2C digital output, ±2% accuracy, and 4.75V ~ 5.25V supply voltage range. The operating temperature range (-20°C ~ 105°C) and maximum pressure rating (60PSI) are identical. Port configuration differs minimally (2.31mm versus 2.29mm tube diameter), representing a negligible mechanical tolerance variation within standard tubing specifications. The ASDXACX030PA7A5 carries active product status with RoHS compliance and unlimited moisture sensitivity rating. Current inventory availability is 925 units. This part is suitable for direct PCB layout substitution with no firmware or signal conditioning modifications required.

ASDXRRX001PGAA5 (Similar Part - Application-Dependent)

The ASDXRRX001PGAA5 shares the ASDX series platform and common electrical infrastructure (supply voltage, temperature range, RoHS compliance, 8-DIP through-hole mounting) but differs fundamentally in pressure measurement characteristics. This sensor operates at 1PSI vented gauge pressure with 0.5V ~ 4.5V analog voltage output, contrasting with the 30PSI absolute pressure and I2C digital interface of the main part. The maximum pressure rating is 2PSI, one-thirtieth of the ASDX030A24R-DO specification. This part is not suitable as a direct substitute. Selection of ASDXRRX001PGAA5 requires complete application redesign including signal conditioning circuitry, firmware rewrite, and pressure range validation. High inventory availability (2580 units) does not offset the incompatibility of output interface and pressure specifications.

Frequently Asked Questions (FAQ)

Q: Can ASDXACX030PA7A5 replace ASDX030A24R-DO without PCB modifications?

A: Yes. The ASDXACX030PA7A5 maintains identical 8-DIP through-hole pin configuration, I2C interface protocol, and electrical specifications. The 0.02mm tube port diameter difference (2.31mm versus 2.29mm) is within standard tubing tolerance and does not require mechanical redesign. No firmware changes are necessary.

Q: What is the significance of the port size difference between ASDX030A24R-DO (2.29mm) and ASDXACX030PA7A5 (2.31mm)?

A: The 0.02mm difference represents a tolerance variation within standard barbed and barbless tubing specifications. Both sizes accommodate 0.09" nominal tubing. Tubing compatibility is determined by the barb geometry and material properties rather than the absolute diameter specification. Barbless port style on both parts ensures consistent sealing performance across this minor dimensional variation.

Q: Why is ASDXRRX001PGAA5 listed as a similar part rather than a direct substitute?

A: ASDXRRX001PGAA5 differs in three critical parameters: (1) Pressure Type is Vented Gauge rather than Absolute, (2) Operating Pressure is 1PSI versus 30PSI, and (3) Output Type is Analog Voltage (0.5V ~ 4.5V) rather than I2C digital. These differences require complete application redesign including signal conditioning and firmware rewrite. The part is not interchangeable at the PCB level.

Q: Are all three parts RoHS compliant?

A: Yes. ASDX030A24R-DO, ASDXACX030PA7A5, and ASDXRRX001PGAA5 all carry RoHS Compliant status. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Q: What is the current availability status for substitutes?

A: ASDXACX030PA7A5 (direct substitute) has 925 units in stock. ASDXRRX001PGAA5 (similar part) has 2580 units in stock. The original ASDX030A24R-DO has 986 units remaining in inventory but carries obsolete product status.

Q: Does the ASDXACX030PA7A5 require I2C address reconfiguration?

A: No information regarding I2C address configuration is provided in the component specifications. Consult the device datasheet for I2C address settings and protocol compatibility verification with existing host controller firmware.

Q: Can ASDXACX030PA7A5 operate in the same temperature range as the original part?

A: Yes. Both ASDX030A24R-DO and ASDXACX030PA7A5 operate across -20°C to 105°C. Temperature compensation is implemented in both designs. No thermal performance degradation occurs with substitution.
