XPC15DTH Equivalent & Substitute Parts Reference

Part Overview

The XPC15DTH 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. This component features a Wheatstone Bridge output with 0 mV to 90 mV signal range at 12V supply, temperature compensation, and barbed male tube connections at 0.19" (4.83mm) diameter.

The XPC15DTH is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing system maintenance, repair, and new design implementations where this sensor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XPC15DTH is determined by the following critical parameters:

Primary Matching Criteria:

• Differential pressure type at 15 PSI (103.42 kPa) operating pressure
• Wheatstone Bridge output configuration
• 0 mV to 90 mV output signal range at 12V supply
• ±1% accuracy specification
• 4-SIP Module package format
• Through hole mounting capability
• Temperature compensation feature
• Operating temperature range of -25°C to 85°C

Secondary Compatibility Factors:

• Supply voltage range (minimum 12V support required)
• Port style and size (mechanical interface considerations)
• Maximum pressure rating (must equal or exceed 15 PSI operating point)
• RoHS compliance status

The substitute part 15 PSI-D-CGRADE-MINI from Amphenol All Sensors Corporation meets all primary matching criteria. Minor variations in port diameter (0.18" versus 0.19") and port style (barbless versus barbed) represent mechanical interface differences that require system-level evaluation during integration.

Parameter Comparison

Engineering Selection Recommendations

The 15 PSI-D-CGRADE-MINI qualifies as a functional equivalent to the XPC15DTH based on matching electrical specifications, output characteristics, and environmental operating parameters. The substitute part is currently in active production status, ensuring supply chain availability for ongoing applications.

Compliance Considerations: Both parts maintain RoHS compliance and identical moisture sensitivity ratings (MSL 1), supporting deployment in regulated manufacturing environments without additional qualification requirements.

Electrical Compatibility: The substitute part operates at a fixed 16V supply voltage, compared to the XPC15DTH's 3V to 16V range. System designs currently operating the XPC15DTH at 12V supply will function identically with the 15 PSI-D-CGRADE-MINI. Designs utilizing supply voltages below 16V require verification that the substitute part's fixed 16V specification aligns with available power distribution architecture.

Mechanical Interface Differences: The port diameter reduction from 0.19" to 0.18" and transition from barbed to barbless connection style represent physical interface variations. Tubing compatibility and connection retention characteristics must be evaluated within the specific application context. These differences do not affect electrical performance or sensor accuracy.

Maximum Pressure Rating: The 15 PSI-D-CGRADE-MINI provides a higher maximum pressure rating (60 PSI versus 45 PSI), offering enhanced overpressure protection without affecting nominal operating characteristics at 15 PSI.

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-D-CGRADE-MINI directly replace the XPC15DTH in existing designs?

A: Electrical and functional compatibility is confirmed. The substitute part produces identical output signals (0 mV to 90 mV at 12V) with matching accuracy (±1%) and temperature compensation across the -25°C to 85°C operating range. Mechanical interface compatibility depends on tubing diameter tolerance and connection method requirements in the specific application. Port diameter difference (0.19" to 0.18") and barbed-to-barbless transition require physical integration assessment.

Q: What is the impact of the fixed 16V supply voltage on the 15 PSI-D-CGRADE-MINI?

A: The substitute part operates at a single 16V supply specification, whereas the XPC15DTH accepts 3V to 16V. Applications currently powered at 12V will function without modification. Systems requiring operation below 16V or utilizing variable supply voltage must confirm that 16V supply availability exists in the target application architecture.

Q: Are there differences in output signal characteristics between these parts?

A: No. Both parts deliver identical Wheatstone Bridge output in the 0 mV to 90 mV range at 12V supply. Accuracy specifications (±1%), temperature compensation, and operating temperature ranges are equivalent. Signal conditioning and interface electronics require no modification.

Q: How do the port configuration differences affect substitution?

A: The XPC15DTH features barbed male connections at 0.19" diameter; the 15 PSI-D-CGRADE-MINI uses barbless connections at 0.18" diameter. Barbed connections provide mechanical retention through tubing deformation; barbless connections rely on compression or adhesive methods. Tubing compatibility and connection reliability must be verified for the specific application. Diameter tolerance may require tubing adapter evaluation.

Q: Is the higher maximum pressure rating of the 15 PSI-D-CGRADE-MINI a concern?

A: No. The 60 PSI maximum pressure rating on the substitute part exceeds the 45 PSI rating of the XPC15DTH. This provides additional overpressure protection margin without affecting performance at the 15 PSI nominal operating point. Both parts maintain identical accuracy and output characteristics within the 15 PSI operating specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the XPC15DTH and 15 PSI-D-CGRADE-MINI are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity ratings, supporting deployment in regulated manufacturing and environmental compliance requirements.
