XPC15DTC Pressure Sensor Equivalent & Substitute Parts

Part Overview

The XPC15DTC is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 15 PSI (103.42 kPa) differential pressure measurement. The sensor outputs a Wheatstone Bridge signal of 0 mV to 90 mV at 12V supply voltage with ±1% accuracy and temperature compensation across the -25°C to 85°C operating range.

The XPC15DTC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this sensor.

Engineering Selection Recommendations

The 15 PSI-D-CGRADE-MINI from Amphenol All Sensors Corporation is a functional equivalent to the obsolete XPC15DTC. Selection of this substitute is supported by the following engineering factors:

Product Status: The substitute part is classified as Active, ensuring ongoing availability and supply chain support compared to the obsolete XPC15DTC.

Electrical Compatibility: Both sensors provide identical Wheatstone Bridge output (0 mV ~ 90 mV at 12V) with ±1% accuracy, enabling direct signal processing without circuit modification.

Mechanical Compatibility: Both sensors are packaged as 4-SIP Through Hole modules with identical operating temperature ranges (-25°C ~ 85°C) and temperature compensation features.

Compliance: Both parts are RoHS Compliant with MSL Rating 1 (Unlimited), meeting environmental and reliability standards.

Port Configuration Consideration: The substitute part features a 0.18" (4.57 mm) barbless tube connection compared to the original 0.19" (4.83 mm) barbed configuration. This represents a minor dimensional variation that may require tubing adapter evaluation during integration.

Supply Voltage: The substitute part specifies 16V supply voltage, which is within the operational range of the original part's 3V ~ 16V specification, ensuring compatibility with existing power supplies.

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-D-CGRADE-MINI directly replace the XPC15DTC without circuit modifications?

A: Yes. Both sensors provide identical Wheatstone Bridge output signals (0 mV ~ 90 mV at 12V) with ±1% accuracy. No signal conditioning circuit changes are required.

Q: What is the significance of the port size difference (0.19" vs. 0.18")?

A: The port size difference is minor (0.26 mm). The substitute part uses a barbless tube configuration compared to the original barbed design. Tubing compatibility should be verified during integration. Adapter fittings may be required depending on existing tubing specifications.

Q: Is the substitute part suitable for the same operating temperature range?

A: Yes. Both sensors operate across -25°C to 85°C with temperature compensation, ensuring equivalent thermal performance.

Q: What is the difference in maximum pressure ratings?

A: The substitute part has a higher maximum pressure rating (60 PSI vs. 45 PSI). This provides additional safety margin and does not affect compatibility for 15 PSI differential pressure applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the XPC15DTC and 15 PSI-D-CGRADE-MINI are RoHS Compliant with MSL Rating 1 (Unlimited), meeting environmental and reliability requirements.

Q: What supply voltage should be used with the substitute part?

A: The substitute part is specified for 16V supply. The original part accepts 3V ~ 16V. Both sensors operate correctly at 12V, which is the standard supply voltage for the Wheatstone Bridge output specification.

Q: Is the 4-SIP Through Hole package identical between both parts?

A: Yes. Both sensors use the same 4-SIP Module package type with Through Hole mounting, ensuring PCB footprint compatibility.
