XPC100GTC Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The XPC100GTC is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 100 PSI (689.48 kPa) pressure measurement. This sensor features a Wheatstone Bridge output with 0 mV to 100 mV signal range at 12V supply, temperature compensation, and barbed male connection at 0.19" (4.83mm) tube diameter.

The XPC100GTC is classified as an obsolete product. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure continued availability, and support legacy equipment maintenance where direct replacement with the original part number is no longer feasible.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPC100GTC pressure sensor is determined by the following critical parameters that must align between the original and substitute part:

Primary Substitution Criteria:

• Operating pressure rating: 100 PSI (689.48 kPa)
• Pressure type: Vented gauge configuration
• Output type: Wheatstone Bridge
• Port connection: Male barbed tube, 0.19" (4.83mm) diameter
• Mounting configuration: Through hole, 4-SIP package
• Temperature compensation: Required
• RoHS compliance: Required

Secondary Compatibility Parameters:

• Supply voltage range must overlap with system requirements
• Output signal range must be compatible with signal conditioning circuits
• Operating temperature range must encompass application environment
• Maximum pressure rating must equal or exceed 100 PSI nominal rating

The TSCSHNN100PGUCV qualifies as a substitute part because it maintains the same operating pressure, pressure type, output type, port configuration, mounting style, and package format. Differences in output signal range, supply voltage, accuracy, and temperature range represent design variations that do not preclude substitution when system signal conditioning and power supply specifications are verified.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The TSCSHNN100PGUCV pressure sensor is a valid substitute for the obsolete XPC100GTC based on matching core functional parameters: identical 100 PSI operating pressure, vented gauge configuration, Wheatstone Bridge output topology, barbed male port connection, through-hole 4-SIP mounting, and temperature compensation.

Critical Verification Requirements:

1. Supply Voltage Compatibility: The XPC100GTC operates across 3V to 16V; the TSCSHNN100PGUCV operates across 1.5V to 12V. Verify that the system power supply voltage falls within the 1.5V to 12V overlap range. If the original system supplies voltage above 12V, substitution is not feasible without power supply modification.

2. Signal Conditioning Adjustment: The XPC100GTC produces 0 mV to 100 mV output at 12V supply; the TSCSHNN100PGUCV produces 0 mV to 30.5 mV output at 5V supply. The signal conditioning circuit must be recalibrated to accommodate the lower output voltage range of the substitute part.

3. Package Port Orientation: Both parts use 4-SIP packages; however, the TSCSHNN100PGUCV specifies "Side Port" configuration. Verify that the port orientation is compatible with the existing tubing and mounting layout.

4. Product Status and Availability: The TSCSHNN100PGUCV is an active product with current manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete XPC100GTC.

5. Compliance Verification: Both parts are RoHS compliant with MSL 1 rating, maintaining regulatory and environmental compliance requirements.

Performance Enhancements with Substitution:

The TSCSHNN100PGUCV offers improved accuracy (±0.15% versus ±1%) and extended low-temperature operation (-40°C versus -25°C minimum), providing performance advantages in precision measurement and cold environment applications.

Frequently Asked Questions (FAQ)

Q: Can the TSCSHNN100PGUCV directly replace the XPC100GTC without any circuit modifications?

A: Direct mechanical and electrical substitution requires verification of three factors: (1) system supply voltage must be within the 1.5V to 12V range of the substitute part, (2) signal conditioning circuits must be recalibrated for the lower 0 mV to 30.5 mV output range, and (3) package port orientation (side port configuration) must be compatible with existing tubing connections. If all three conditions are met, substitution is feasible.

Q: What is the significance of the output signal range difference between these two sensors?

A: The XPC100GTC produces 100 mV full-scale output at 12V supply, while the TSCSHNN100PGUCV produces 30.5 mV full-scale output at 5V supply. This represents a different sensor sensitivity design. The signal conditioning circuit (amplifier, analog-to-digital converter, or measurement instrument) must be adjusted to accommodate the lower output voltage of the substitute part to maintain measurement accuracy and resolution.

Q: Are both sensors suitable for the same pressure range applications?

A: Yes. Both sensors are rated for 100 PSI (689.48 kPa) operating pressure with vented gauge configuration. Maximum pressure ratings are equivalent (250 PSI for XPC100GTC, 245 PSI for TSCSHNN100PGUCV), providing equivalent overpressure protection. Both are suitable for identical pressure measurement applications.

Q: What does "vented gauge" pressure type mean?

A: Vented gauge pressure measurement references atmospheric pressure through a vent port. Both the XPC100GTC and TSCSHNN100PGUCV measure pressure relative to ambient atmospheric conditions rather than absolute vacuum. This configuration is appropriate for applications such as fluid level measurement, filter pressure monitoring, and process pressure control where atmospheric reference is acceptable.

Q: Why is the TSCSHNN100PGUCV classified as "Active" while the XPC100GTC is "Obsolete"?

A: The XPC100GTC has been discontinued by the manufacturer and is no longer in production. The TSCSHNN100PGUCV is part of Honeywell's current TruStability® TSC product line and continues to be manufactured. For new designs and legacy equipment maintenance, the active substitute part ensures ongoing availability and manufacturer support.

Q: Does the improved accuracy of the TSCSHNN100PGUCV (±0.15% versus ±1%) require system recalibration?

A: The improved accuracy specification of the substitute part does not require recalibration if the original system was designed to tolerate ±1% accuracy. The substitute part will perform within the original system's accuracy requirements while offering better measurement precision. However, if the application requires full utilization of the improved ±0.15% accuracy, signal conditioning and calibration procedures should be reviewed.

Q: Are there any moisture sensitivity or handling differences between these sensors?

A: Both sensors have identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly. Standard component handling practices are sufficient for both parts.

Q: What is the significance of the port size difference (4.83mm versus 4.78mm)?

A: Both sensors feature male barbed tube connections at nominally 0.19" (approximately 4.8mm) diameter. The 0.05mm dimensional variation is within normal manufacturing tolerance for barbed tubing connections and does not affect functional compatibility. Standard tubing sized for 0.19" connections will function with both sensors.
