CPC15GFC Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The CPC15GFC is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 15 PSI (103.42 kPa) pressure measurement. This sensor outputs a Wheatstone Bridge signal of 0 mV to 90 mV at 12V supply voltage and features temperature compensation across an operating range of -25°C to 85°C.

The CPC15GFC is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support legacy equipment maintenance where direct replacement availability is limited.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC15GFC pressure sensor is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Operating Pressure: 15 PSI (103.42 kPa)
• Pressure Type: Vented Gauge
• Output Type: Wheatstone Bridge
• Output Signal: 0 mV ~ 90 mV (12V)
• Mounting Type: Through Hole
• Package / Case: 4-SIP Module
• Operating Temperature Range: -25°C ~ 85°C

Allowable Variation Parameters:

• Port Size and Port Style: Minor dimensional differences in tube diameter and connection style are permissible if the barbed or barbless connection maintains functional compatibility with the application's tubing specifications
• Accuracy: Substitute parts may have equal or superior accuracy (lower tolerance)
• Voltage Supply Range: Substitute parts must support the 12V nominal supply; extended supply voltage ranges are acceptable
• Maximum Pressure: Substitute parts must equal or exceed the original maximum pressure rating

The substitute part 15 PSI-GF-CGRADE-MINI meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 15 PSI-GF-CGRADE-MINI manufactured by Amphenol All Sensors Corporation is a functional equivalent for the obsolete CPC15GFC. Selection of this substitute is supported by the following engineering criteria:

Compliance and Certification: Both the original part and substitute are RoHS Compliant and carry MSL Rating 1 (Unlimited), ensuring equivalent environmental and reliability standards.

Product Status: The CPC15GFC is obsolete, whereas the 15 PSI-GF-CGRADE-MINI is active. Selection of an active product ensures ongoing availability, technical support, and supply chain stability for new procurements and system maintenance.

Electrical and Functional Equivalence: The substitute part delivers identical output signal characteristics (0 mV ~ 90 mV at 12V), identical pressure measurement range (15 PSI vented gauge), and identical operating temperature range (-25°C ~ 85°C). Both employ Wheatstone Bridge output topology and 4-SIP Module packaging.

Performance Enhancement: The substitute part offers superior accuracy (±1% versus ±2%) and higher maximum pressure rating (60 PSI versus 45 PSI), providing enhanced measurement precision and overpressure protection without compromising functional compatibility.

Port Configuration Consideration: The substitute part features a 0.18" (4.57 mm) barbless tube connection versus the original 0.15" (3.8 mm) barbed connection. System integration requires verification that tubing diameter and connection method are compatible with the application's pneumatic interface. Adapter fittings or tubing replacement may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-GF-CGRADE-MINI directly replace the CPC15GFC without circuit modifications?

A: Yes, the substitute part provides identical Wheatstone Bridge output signal (0 mV ~ 90 mV at 12V) and operates within the same voltage supply range. No signal conditioning circuit modifications are required. However, the pneumatic port connection differs in diameter and style, requiring tubing compatibility assessment.

Q: What is the significance of the port size difference (0.15" versus 0.18")?

A: The port size difference reflects the tube outer diameter for pneumatic connections. The original CPC15GFC uses 0.15" (3.8 mm) barbed tubing, while the substitute uses 0.18" (4.57 mm) barbless tubing. System integration requires either tubing replacement or use of appropriate adapter fittings to maintain pneumatic seal integrity.

Q: Does the substitute part's superior accuracy (±1% versus ±2%) affect system compatibility?

A: No. Superior accuracy is a performance enhancement that does not compromise compatibility. Systems designed for ±2% accuracy will function correctly with a ±1% accurate sensor, as the substitute meets or exceeds the original specification.

Q: Is the substitute part's higher maximum pressure rating (60 PSI versus 45 PSI) relevant to system selection?

A: The higher maximum pressure rating provides additional overpressure protection margin. This is beneficial for system reliability but does not affect functional compatibility, as the operating pressure remains 15 PSI in both cases.

Q: Are there supply chain advantages to selecting the active substitute part?

A: Yes. The 15 PSI-GF-CGRADE-MINI is an active product with ongoing manufacturing and distribution support. The CPC15GFC is obsolete, making future procurement difficult. Selection of the active substitute ensures long-term availability and technical support.

Q: What is the difference between barbed and barbless port styles?

A: Barbed ports feature inward-facing barbs that grip tubing when inserted, relying on friction for retention. Barbless ports require external hose clamps or compression fittings for secure tubing attachment. System design must accommodate the appropriate connection method for the selected sensor.

Q: Can the substitute part operate at the original part's minimum supply voltage (3V)?

A: The substitute part is specified for 16V supply voltage. While the original part supports 3V ~ 16V range, the substitute operates at 16V nominal. System power supply must provide 16V to the substitute part. Verify that the application's power supply is compatible with this requirement.
