Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDXL10D44R is determined by alignment across the following critical parameters:

Output Characteristics: Both the main part and substitute must provide analog voltage output in the 0.5 V ~ 4.5 V range with ±2% accuracy to ensure signal compatibility with existing analog-to-digital conversion circuits and signal conditioning electronics.

Electrical Supply: Supply voltage range of 4.75 V ~ 5.25 V must be maintained to ensure proper sensor operation within the specified power budget.

Physical Interface: Port configuration (Male - 0.09" tube, dual barbless design) and termination style (PC Pin) must match to enable direct mechanical and electrical connection without adapter modifications.

Package and Mounting: The 8-DIP module package with through-hole mounting type ensures compatibility with existing PCB layouts and assembly processes.

Environmental Performance: Operating temperature range of -20°C ~ 105°C and temperature compensation features must be preserved for applications requiring stable performance across thermal variations.

Compliance: RoHS compliance and MSL rating of 1 (Unlimited) must be maintained for regulatory and manufacturing process compatibility.

The substitute part ASDXRRX001PGAA5 shares these core electrical, mechanical, and environmental specifications. However, the pressure type differs: the main part measures differential pressure (0.36 PSI), while the substitute measures vented gauge pressure (1 PSI). This distinction affects application suitability and must be evaluated against system requirements.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The ASDXRRX001PGAA5 is classified as an active product from the same manufacturer, providing long-term availability and supply chain continuity compared to the obsolete ASDXL10D44R. Both components maintain RoHS compliance and identical MSL ratings, ensuring compatibility with current manufacturing and environmental standards.

Pressure Measurement Consideration: The primary distinction between these components is the pressure measurement type and operating range. The ASDXL10D44R measures differential pressure at 0.36 PSI, while the ASDXRRX001PGAA5 measures vented gauge pressure at 1 PSI. Selection between these parts must be based on the specific pressure measurement requirement of the application. Differential pressure measurement and vented gauge pressure measurement are fundamentally different measurement modes and cannot be interchanged without system-level evaluation.

Electrical and Mechanical Compatibility: Both parts share identical output voltage ranges (0.5 V ~ 4.5 V), supply voltage specifications (4.75 V ~ 5.25 V), accuracy (±2%), and termination characteristics (PC Pin, 8-DIP module, through-hole mounting). The port size difference of 0.02 mm (2.29 mm versus 2.31 mm) falls within standard manufacturing tolerances for male tube connectors.

Temperature Performance: Both components operate across the identical temperature range (-20°C ~ 105°C) with temperature compensation, ensuring stable performance in thermally variable environments.

Frequently Asked Questions (FAQ)

Q: Can the ASDXRRX001PGAA5 directly replace the ASDXL10D44R in an existing circuit?

A: Direct electrical and mechanical replacement is possible due to matching output voltage ranges, supply voltage specifications, accuracy ratings, PC Pin termination, and 8-DIP module packaging. However, the pressure measurement type differs: differential versus vented gauge. System-level evaluation is required to confirm that vented gauge pressure measurement satisfies the original application requirements.

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

A: Differential pressure measurement (ASDXL10D44R) compares pressure between two separate input ports and outputs the difference. Vented gauge pressure measurement (ASDXRRX001PGAA5) measures pressure relative to atmospheric pressure through a single vented port. These are distinct measurement modes applicable to different system architectures.

Q: Are the port sizes compatible between these two sensors?

A: The port sizes are 0.09" (2.29 mm) for the ASDXL10D44R and 0.09" (2.31 mm) for the ASDXRRX001PGAA5. The 0.02 mm difference is within standard manufacturing tolerances for male tube connectors and does not prevent mechanical connection.

Q: Do both sensors require the same supply voltage?

A: Yes. Both the ASDXL10D44R and ASDXRRX001PGAA5 require a supply voltage of 4.75 V ~ 5.25 V and produce identical output voltage ranges of 0.5 V ~ 4.5 V, ensuring compatibility with existing power supply and signal conditioning circuits.

Q: What is the significance of the product status difference?

A: The ASDXL10D44R is classified as obsolete, indicating discontinued manufacturing and limited future availability. The ASDXRRX001PGAA5 is classified as active, indicating current production and long-term supply chain availability. For new designs or long-term system support, the active product is preferred.

Q: Are both sensors RoHS compliant?

A: Yes. Both the ASDXL10D44R and ASDXRRX001PGAA5 are RoHS compliant and carry an MSL rating of 1 (Unlimited), ensuring compatibility with current manufacturing processes and environmental regulations.

Q: What is the maximum pressure rating difference between these sensors?

A: The ASDXL10D44R has a maximum pressure rating of 3 PSI (20.68 kPa), while the ASDXRRX001PGAA5 has a maximum pressure rating of 2 PSI (13.79 kPa). Applications exposing the sensor to pressures between 2 PSI and 3 PSI must use the ASDXL10D44R to remain within safe operating limits.

Q: Do both sensors provide temperature compensation?

A: Yes. Both the ASDXL10D44R and ASDXRRX001PGAA5 feature temperature compensation and operate across the identical temperature range of -20°C ~ 105°C, ensuring stable output across thermal variations.
