ASCX100AN Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASCX100AN is a pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for absolute pressure measurement applications. This component features a 100 PSI (689.48 kPa) operating range with analog voltage output (0.25 V ~ 4.75 V) and is configured as a 6-SIP module with through-hole mounting. The ASCX100AN is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASCX100AN is determined by strict alignment of the following critical parameters:

Pressure Specifications: Operating pressure of 100 PSI (689.48 kPa) absolute, maximum pressure rating of 150 PSI (1034.21 kPa), and absolute pressure type are non-negotiable requirements.

Electrical Interface: Output voltage range of 0.25 V ~ 4.75 V and analog voltage output type establish the signal compatibility with existing circuit designs.

Mechanical Interface: Male barbless port configuration with 0.19" (4.8 mm) tube size ensures direct compatibility with pneumatic connections.

Environmental Compliance: Operating temperature range of -25°C ~ 105°C and RoHS compliance status must be maintained.

Mounting Configuration: Through-hole termination style with PC pin configuration is required for board-level integration.

The substitute part 100 PSI-A-4V-ASCX meets all critical pressure, electrical output, mechanical port, environmental, and mounting requirements. Variations in package configuration (4-SIP versus 6-SIP), accuracy specification (±0.5% versus ±1%), supply voltage range (4.5 V ~ 5.5 V versus 4.5 V ~ 16 V), and output type classification (Wheatstone Bridge versus Analog Voltage) do not preclude functional substitution when the primary electrical output characteristics and pressure specifications remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ASCX100AN is classified as obsolete. The substitute part 100 PSI-A-4V-ASCX carries active product status from Amphenol All Sensors Corporation, ensuring ongoing availability and manufacturing support.

Compliance Status: Both components maintain RoHS compliance. The substitute part carries ROHS3 certification, representing current regulatory alignment. Both components are REACH unaffected and classified under ECCN EAR99.

Functional Compatibility: The substitute part delivers equivalent pressure measurement capability across the 100 PSI operating range with identical output voltage characteristics (0.25 V ~ 4.75 V). Mechanical interface compatibility is confirmed through identical port configuration (male barbless 0.19" tube).

Performance Differential: The substitute part provides improved accuracy (±0.5% versus ±1%), which represents enhanced measurement precision without introducing incompatibility. The restricted supply voltage range (4.5 V ~ 5.5 V versus 4.5 V ~ 16 V) requires verification that existing power supply designs operate within the narrower specification window.

Package Configuration: The transition from 6-SIP to 4-SIP packaging requires PCB layout modification. Pin-to-pin electrical functionality remains compatible; physical board footprint redesign is necessary.

Frequently Asked Questions (FAQ)

Q: Can the 100 PSI-A-4V-ASCX directly replace the ASCX100AN without circuit modification?

A: Electrical output characteristics are compatible (0.25 V ~ 4.75 V analog voltage output). However, the package transition from 6-SIP to 4-SIP requires PCB footprint redesign. Additionally, verify that the system power supply operates within the substitute part's 4.5 V ~ 5.5 V range, as the original part accepts 4.5 V ~ 16 V.

Q: What is the significance of the accuracy difference (±1% versus ±0.5%)?

A: The substitute part provides tighter accuracy specification, representing improved measurement precision. This does not create incompatibility; systems designed for ±1% accuracy will function correctly with ±0.5% components.

Q: Are the pressure specifications identical between the two parts?

A: Yes. Both components operate at 100 PSI (689.48 kPa) absolute pressure with 150 PSI (1034.21 kPa) maximum pressure rating. Pressure type, port size, and port style are identical.

Q: What does the output type difference (Analog Voltage versus Wheatstone Bridge) mean?

A: Both parts deliver 0.25 V ~ 4.75 V output. The classification difference reflects internal signal conditioning architecture but does not affect external circuit compatibility when output voltage characteristics match.

Q: Is the supply voltage range restriction a concern?

A: The substitute part requires 4.5 V ~ 5.5 V supply voltage, compared to the original part's 4.5 V ~ 16 V range. Confirm that existing power supply designs operate within 5.5 V maximum. If the system requires higher supply voltages, the substitute part is not suitable.

Q: Are both parts RoHS compliant?

A: Yes. The ASCX100AN is RoHS compliant. The substitute part 100 PSI-A-4V-ASCX carries ROHS3 certification, representing current regulatory compliance standards.

Q: What is the impact of the 4-SIP versus 6-SIP package difference?

A: Package configuration affects PCB footprint and pin count. The 4-SIP configuration requires board redesign. Verify pin assignment compatibility and ensure the reduced pin count does not eliminate required functionality in your application.
