ASCX15DN Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The ASCX15DN is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, rated for 15PSI (103.42kPa) differential measurement with analog voltage output (0.25V ~ 4.75V). The sensor features a 6-SIP module package with male barbless tube ports (0.19" / 4.8mm) and is designed for through-hole board mount applications.

The ASCX15DN is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASCX15DN requires matching the following critical parameters:

Pressure Measurement Characteristics:

• Operating pressure rating of 15PSI (103.42kPa)
• Differential or vented gauge pressure type
• Analog voltage output with 0.25V ~ 4.75V range

Physical and Electrical Interface:

• Male barbless tube ports, 0.19" (4.8mm) diameter, dual configuration
• Through-hole mounting capability
• PC pin termination style
• Supply voltage compatibility (4.5V minimum)

Environmental and Compliance Requirements:

• Operating temperature range spanning -25°C to 105°C
• RoHS compliance
• Amplified output with temperature compensation

The substitute parts identified below satisfy these critical parameters with variations in pressure type (vented gauge vs. differential), package configuration (4-SIP vs. 6-SIP), and accuracy specifications.

Parameter Comparison

Engineering Selection Recommendations

SSCSNBN015PGAB5 (Primary Substitute - Honeywell TruStability® SSC Series)

The SSCSNBN015PGAB5 is the recommended primary substitute for the ASCX15DN. This part maintains identical operating pressure (15PSI), output voltage range (0.25V ~ 4.75V), port configuration (male barbless 0.19" dual tubes), and through-hole mounting. The SSCSNBN015PGAB5 is active product status with RoHS compliance. The primary difference is pressure type (vented gauge vs. differential) and package format (4-SIP vs. 6-SIP). The vented gauge configuration is suitable for applications measuring pressure relative to atmospheric conditions. The improved accuracy specification (±0.25% vs. ±1%) provides enhanced measurement precision.

SSCSNBN015PGAA5 (Secondary Substitute - Honeywell TruStability® SSC Series)

The SSCSNBN015PGAA5 offers identical mechanical and electrical interface characteristics to SSCSNBN015PGAB5, with the exception of output voltage range (0.5V ~ 4.5V vs. 0.25V ~ 4.75V). This part is suitable when the reduced output span is compatible with system signal conditioning. Active product status and RoHS compliance are confirmed.

15 PSI-D-4V-ASCX (Differential Pressure Alternative - Amphenol All Sensors)

The 15 PSI-D-4V-ASCX maintains differential pressure measurement type matching the ASCX15DN, with identical operating pressure (±15PSI), output range (0.25V ~ 4.75V), and operating temperature span (-25°C ~ 105°C). This part is manufactured by Amphenol All Sensors Corporation and carries ROHS3 compliance. The 4-SIP package differs from the 6-SIP module of the ASCX15DN. Output type is specified as Wheatstone Bridge with ±0.5% accuracy. This part is active product status.

All three substitute parts are currently in active production with confirmed inventory availability and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can SSCSNBN015PGAB5 directly replace ASCX15DN in existing designs?

A: Direct replacement requires evaluation of pressure type compatibility. SSCSNBN015PGAB5 measures vented gauge pressure (relative to atmosphere), while ASCX15DN measures differential pressure (between two independent ports). If the application requires differential measurement, SSCSNBN015PGAB5 is not suitable. The 15 PSI-D-4V-ASCX maintains differential measurement capability. Package footprint differs (4-SIP vs. 6-SIP), requiring PCB layout verification.

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

A: Differential pressure sensors measure the pressure difference between two independent input ports. Vented gauge pressure sensors measure pressure relative to atmospheric pressure through a vent port. Application requirements determine which measurement type is appropriate.

Q: Are the Honeywell TruStability® SSC parts (SSCSNBN015PGAA5 and SSCSNBN015PGAB5) interchangeable?

A: Both parts share identical mechanical interfaces, electrical termination, and operating characteristics. The primary difference is output voltage range: SSCSNBN015PGAA5 outputs 0.5V ~ 4.5V, while SSCSNBN015PGAB5 outputs 0.25V ~ 4.75V. Selection depends on signal conditioning requirements and ADC input specifications.

Q: Does the reduced operating temperature range of SSCSNBN015PGAB5 (-40°C ~ 85°C vs. -25°C ~ 105°C) affect substitution suitability?

A: The SSCSNBN015PGAB5 operating range is narrower than ASCX15DN. If the application requires operation at temperatures below -40°C or above 85°C, SSCSNBN015PGAB5 is not suitable. The 15 PSI-D-4V-ASCX maintains the full -25°C ~ 105°C range.

Q: What is the significance of the improved accuracy specification in substitute parts?

A: SSCSNBN015PGAB5 and SSCSNBN015PGAA5 specify ±0.25% accuracy compared to ASCX15DN's ±1%. This represents a four-fold improvement in measurement precision. Enhanced accuracy reduces measurement uncertainty and may improve system performance in applications with tight tolerance requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. SSCSNBN015PGAB5 and SSCSNBN015PGAA5 carry RoHS compliance certification. The 15 PSI-D-4V-ASCX carries ROHS3 compliance certification. All parts meet current environmental and regulatory requirements.

Q: What inventory status should be considered for production planning?

A: ASCX15DN (obsolete) has 1033 pcs available. SSCSNBN015PGAB5 has 1022 pcs available. SSCSNBN015PGAA5 has 859 pcs available. 15 PSI-D-4V-ASCX has 1138 pcs available. All substitute parts are active production items with confirmed stock levels.
