Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASDX015D44R are identified based on strict parameter compatibility within the ASDX series. The substitution logic is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Output Type: Analog Voltage
• Output Range: 0.5V ~ 4.5V
• Supply Voltage: 4.75V ~ 5.25V
• Accuracy: ±2%

Mechanical & Physical Compatibility Parameters:

• Package / Case: 8-DIP Module
• Termination Style: PC Pin
• Mounting Type: Through Hole
• Port Style: Barbless
• Operating Temperature: -20°C ~ 105°C

Pressure Measurement Parameters:

• Operating Pressure Range
• Pressure Type (Differential vs. Vented Gauge)
• Maximum Pressure Rating

The ASDX015D44R operates as a differential pressure sensor. Direct substitutes must maintain the same electrical output characteristics, 8-DIP package format, and through-hole mounting configuration. Parts with different pressure types (vented gauge vs. differential) or significantly different pressure ranges are classified as similar alternatives rather than direct equivalents, as they serve different measurement applications.

Engineering Selection Recommendations

ASDXRRX015PGAA5 - Direct Substitute (Recommended for Active Designs)

The ASDXRRX015PGAA5 is the primary substitute for the obsolete ASDX015D44R. This part maintains electrical and mechanical compatibility across all critical parameters: identical 8-DIP package, PC pin termination, 0.5V to 4.5V output range, ±2% accuracy, and 4.75V to 5.25V supply voltage specification. The ASDXRRX015PGAA5 is currently in active production status with 10,100 units in stock, ensuring long-term availability and supply chain continuity.

The primary functional difference is the pressure measurement type: ASDXRRX015PGAA5 operates as a vented gauge pressure sensor, whereas ASDX015D44R measures differential pressure. Both maintain the same 15PSI operating pressure rating and 30PSI maximum pressure specification. The port size differs marginally (2.31mm vs. 2.29mm), which is within standard manufacturing tolerance for barbless tube connections.

Both parts are RoHS Compliant with MSL Rating 1 (Unlimited), ensuring regulatory compliance and moisture handling compatibility.

ASDXRRX001PGAA5 - Similar Alternative (Limited Compatibility)

The ASDXRRX001PGAA5 shares the same electrical output characteristics, 8-DIP package format, and through-hole mounting configuration as the ASDX015D44R. However, this part operates at a significantly lower pressure range (1PSI operating pressure, 2PSI maximum) and is classified as a similar alternative rather than a direct substitute. Selection of ASDXRRX001PGAA5 is appropriate only for applications requiring low-pressure measurement within the 1PSI range and is not suitable for systems designed for 15PSI differential or gauge pressure measurement.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX015PGAA5 directly replace ASDX015D44R in existing designs?

A: The ASDXRRX015PGAA5 provides electrical and mechanical compatibility for PCB integration and signal processing. The primary consideration is the pressure measurement type difference: ASDXRRX015PGAA5 measures vented gauge pressure while ASDX015D44R measures differential pressure. Applications requiring differential pressure measurement must evaluate whether vented gauge measurement is functionally equivalent for the specific system requirement.

Q: What is the difference between differential and vented gauge pressure measurement?

A: Differential pressure sensors measure the pressure difference between two independent pressure sources applied to separate ports. Vented gauge pressure sensors measure pressure relative to atmospheric pressure through a vent port. System design determines which measurement type is appropriate.

Q: Are the port sizes compatible between ASDX015D44R and ASDXRRX015PGAA5?

A: Both parts feature male barbless tube connections with nominal 0.09" diameter. The ASDX015D44R specifies 2.29mm while ASDXRRX015PGAA5 specifies 2.31mm. This 0.02mm difference is within standard manufacturing tolerance for barbless tube fittings and does not affect mechanical compatibility.

Q: Is ASDXRRX001PGAA5 suitable as a substitute for ASDX015D44R?

A: ASDXRRX001PGAA5 is not suitable as a direct substitute. This part operates at 1PSI maximum pressure compared to the 15PSI operating pressure of ASDX015D44R. Selection of ASDXRRX001PGAA5 is limited to applications requiring low-pressure measurement within its 1PSI range specification.

Q: What are the regulatory compliance considerations for these parts?

A: All three parts (ASDX015D44R, ASDXRRX015PGAA5, and ASDXRRX001PGAA5) are RoHS Compliant and carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions. REACH Status is Unaffected for all parts, and ECCN classification is EAR99.

Q: What is the supply voltage tolerance for these sensors?

A: All parts operate within a 4.75V to 5.25V supply voltage range. System power supply design must maintain voltage within this specification to ensure accurate sensor operation and output linearity.

Q: Are there temperature compensation features in these sensors?

A: ASDXRRX015PGAA5 and ASDXRRX001PGAA5 include temperature compensation. ASDX015D44R includes both amplified output and temperature compensation features. All parts operate across -20°C to 105°C temperature range.
