SCX15AN Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCX15AN is an active, board-mount absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component operates at 15 PSI (103.42 kPa) absolute pressure with a Wheatstone Bridge output of 0 mV to 90 mV at 12V supply. The sensor features temperature compensation, PC pin termination, and a 6-SIP module package with a barbed male tube port (0.19" / 4.8mm). Identification of equivalent and substitute parts is necessary to support design flexibility, supply chain continuity, and component availability across manufacturing cycles.

Substitute Part Grouping Explanation

Substitution of the SCX15AN with the 15 PSI-A-HGRADE-MINI is based on the following critical parameters that must align for functional equivalence:

Matching Parameters:

Operating Pressure: 15 PSI (103.42 kPa) absolute
Pressure Type: Absolute
Output Type: Wheatstone Bridge
Output Range: 0 mV ~ 90 mV (12V)
Temperature Compensation: Present
Mounting Type: Through Hole
Termination Style: PC Pin

Engineering Selection Recommendations

Both the SCX15AN and 15 PSI-A-HGRADE-MINI are active products with RoHS compliance and equivalent electrical output characteristics. Selection between these components is determined by specific application constraints:

SCX15AN Selection Criteria:

Applications requiring integrated barbed tube port (0.19" / 4.8mm male)
Systems operating at extended low temperatures (-40°C minimum)
Designs with 20V supply voltage availability
6-SIP module package compatibility

15 PSI-A-HGRADE-MINI Selection Criteria:

Applications with no integrated port requirement
Systems operating within -25°C to 85°C temperature range
Designs with 16V supply voltage availability
Compact 4-SIP module package requirement
Applications benefiting from ±0.5% accuracy specification
Systems requiring higher maximum pressure rating (60 PSI)

Both components maintain identical pressure measurement range, Wheatstone Bridge output topology, and temperature compensation functionality. The 15 PSI-A-HGRADE-MINI provides superior accuracy and higher overpressure capability, while the SCX15AN offers integrated pneumatic connection and extended low-temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-A-HGRADE-MINI directly replace the SCX15AN in existing PCB designs?

A: Direct replacement requires evaluation of port interface requirements. The SCX15AN includes a barbed male tube port (0.19" / 4.8mm), while the 15 PSI-A-HGRADE-MINI has no integrated port. If pneumatic connection is required, external tubing adaptation is necessary. Both components use PC pin termination and through-hole mounting, supporting footprint compatibility.

Q: What are the electrical output differences between these sensors?

A: Both sensors deliver identical Wheatstone Bridge output of 0 mV to 90 mV at 12V supply. The 15 PSI-A-HGRADE-MINI specifies ±0.5% accuracy compared to the SCX15AN's ±1% accuracy. This represents improved measurement precision in the substitute component.

Q: Are there temperature range limitations when substituting?

A: The SCX15AN operates from -40°C to 85°C, while the 15 PSI-A-HGRADE-MINI operates from -25°C to 85°C. Applications requiring operation below -25°C must use the SCX15AN. Both sensors maintain temperature compensation across their respective operating ranges.

Q: What supply voltage considerations apply to substitution?

A: The SCX15AN requires 20V supply, while the 15 PSI-A-HGRADE-MINI requires 16V supply. Circuit design must accommodate the specific voltage requirement of the selected component. Both sensors deliver identical output range at their respective supply voltages.

Q: How do the package types differ?

A: The SCX15AN uses a 6-SIP module package, while the 15 PSI-A-HGRADE-MINI uses a 4-SIP module package. The 4-SIP configuration is more compact. PCB layout and footprint design must account for the selected package type.

Q: Are both components suitable for board-mount applications?

A: Yes, both sensors are specified for board-mount applications with through-hole mounting type and PC pin termination. Both are RoHS compliant and suitable for standard PCB assembly processes.
