ASDXRRX015PD7A5 Equivalent & Substitute Parts

Part Overview

The ASDXRRX015PD7A5 is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component operates within a ±15PSI (±103.42kPa) range with 12-bit digital output via I2C interface. The sensor features a male barbless tube port (0.09" / 2.31mm) and is housed in an 8-DIP module with through-hole PC pin termination.

The ASDXRRX015PD7A5 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this sensor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASDXRRX015PD7A5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Pressure Type: Differential
• Operating Pressure Range: ±15PSI (±103.42kPa)
• Output Type: I2C
• Output Resolution: 12-bit
• Supply Voltage: 4.75V ~ 5.25V
• Package Type: 8-DIP Module
• Termination Style: PC Pin
• Mounting Type: Through Hole

Allowable Variation Parameters:

• Port Size and Style (tube diameter and barb configuration)
• Accuracy specification (may be equal or superior)
• Operating Temperature range (may be wider or narrower)
• Features (additional features such as amplified output are acceptable)

The SSCDANV015PD4A5 qualifies as a substitute part because it maintains all mandatory matching parameters while offering improved accuracy (±0.25% versus ±2%) and enhanced features (amplified output). The port configuration differs (0.19" barbed versus 0.09" barbless), which requires mechanical interface verification during integration.

Parameter Comparison

Engineering Selection Recommendations

SSCDANV015PD4A5 as Primary Substitute:

The SSCDANV015PD4A5 is the designated substitute for the obsolete ASDXRRX015PD7A5. Both components are manufactured by Honeywell and maintain identical electrical specifications for pressure range, output protocol, resolution, and supply voltage. Both are RoHS compliant with MSL rating 1.

The SSCDANV015PD4A5 carries active product status, ensuring ongoing availability and manufacturer support. This component offers superior accuracy (±0.25% versus ±2%) and includes amplified output capability, providing enhanced signal integrity.

Integration Considerations:

The primary difference between these components is the port configuration. The ASDXRRX015PD7A5 features a 0.09" barbless dual port, while the SSCDANV015PD4A5 features a 0.19" barbed top port. Mechanical interface adaptation is required. The operating temperature range differs: the ASDXRRX015PD7A5 operates to 105°C maximum, while the SSCDANV015PD4A5 operates to 85°C maximum. Verify that the application's maximum operating temperature does not exceed 85°C.

Both components are through-hole mounted 8-DIP modules with PC pin termination, ensuring PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SSCDANV015PD4A5 directly replace the ASDXRRX015PD7A5 without modification?

A: Electrical and protocol compatibility is direct. However, the port configuration differs (tube diameter and barb style), requiring mechanical interface verification. PCB footprint and pin assignment are compatible for through-hole mounting.

Q: What is the significance of the accuracy difference (±2% versus ±0.25%)?

A: The SSCDANV015PD4A5 provides tighter accuracy specification. If the original application design tolerates ±2% accuracy, the substitute's ±0.25% accuracy is acceptable and represents improved performance. If the application requires exactly ±2% accuracy for specific reasons, this difference must be evaluated.

Q: Are there temperature range limitations when substituting?

A: The ASDXRRX015PD7A5 operates to 105°C; the SSCDANV015PD4A5 operates to 85°C maximum. If the application requires operation above 85°C, the SSCDANV015PD4A5 is not suitable. Verify maximum operating temperature requirements before selection.

Q: What does "amplified output" mean on the SSCDANV015PD4A5?

A: Amplified output refers to signal conditioning integrated into the sensor module, providing enhanced signal strength and noise immunity compared to the standard temperature-compensated output of the ASDXRRX015PD7A5. This is a performance enhancement.

Q: Are both components RoHS compliant?

A: Yes. Both the ASDXRRX015PD7A5 and SSCDANV015PD4A5 are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the port size difference impact?

A: The ASDXRRX015PD7A5 uses 0.09" (2.31mm) barbless tubing; the SSCDANV015PD4A5 uses 0.19" (4.93mm) barbed tubing. Tubing adapters or reconfiguration of pressure line connections may be necessary. Barbed ports provide mechanical retention; barbless ports require alternative securing methods.
