CPCL04GFC Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The CPCL04GFC is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement up to 0.15 PSI (1 kPa). The sensor outputs a Wheatstone Bridge signal of 0 mV to 25 mV at 12V supply voltage with ±2% accuracy and temperature compensation across the -25°C to 85°C operating range.

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

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPCL04GFC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Pressure Type: Vented Gauge
• Operating Pressure: 0.15 PSI (1 kPa)
• Output Type: Wheatstone Bridge
• Output Signal: 0 mV ~ 25 mV (12V)
• Package / Case: 4-SIP Module
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -25°C ~ 85°C
• Maximum Pressure: 3 PSI (20.68 kPa)

Allowable Variations:

• Port Size: Tube diameter may vary (0.15" to 0.18") provided barbed or barbless connection is mechanically compatible with system tubing
• Port Style: Barbed or barbless configurations are interchangeable based on tubing compatibility
• Accuracy: ±1% to ±2% (tighter tolerance acceptable)
• Supply Voltage: 3V ~ 16V range (16V fixed supply acceptable for 3V ~ 16V rated device)
• Manufacturer: Different qualified manufacturers acceptable

The substitute part 4 INCH-GF-CGRADE-MINI (Amphenol All Sensors Corporation) meets all mandatory matching parameters with allowable variations in port diameter and accuracy specification.

Parameter Comparison

Engineering Selection Recommendations

The 4 INCH-GF-CGRADE-MINI from Amphenol All Sensors Corporation is a qualified substitute for the obsolete CPCL04GFC based on the following engineering criteria:

Functional Equivalence: Both sensors provide identical Wheatstone Bridge output (0 mV ~ 25 mV at 12V) for 0.15 PSI vented gauge pressure measurement with matching maximum pressure ratings (3 PSI) and operating temperature ranges (-25°C ~ 85°C).

Compliance Status: The substitute part maintains RoHS compliance and is currently in active production status, ensuring long-term supply chain availability and support compared to the obsolete CPCL04GFC.

Accuracy Improvement: The substitute part offers ±1% accuracy versus the original ±2%, providing enhanced measurement precision without requiring circuit redesign.

Mechanical Considerations: The port diameter increases from 0.15" (3.8 mm) to 0.18" (4.57 mm) and the port style changes from barbed to barbless. System integration requires verification that tubing connectors are compatible with the larger diameter and barbless connection method.

Electrical Compatibility: The substitute part operates at a fixed 16V supply, which falls within the original device's 3V ~ 16V range. Existing power supply configurations are compatible without modification.

Frequently Asked Questions (FAQ)

Q: Can the 4 INCH-GF-CGRADE-MINI directly replace the CPCL04GFC without any modifications?

A: Direct pin-for-pin and electrical replacement is possible. However, the tubing port diameter increases from 0.15" to 0.18" and the connection style changes from barbed to barbless. Verify that system tubing connectors are compatible with these mechanical differences before installation.

Q: What is the significance of the accuracy difference (±2% vs ±1%)?

A: The substitute part provides tighter accuracy specification. This represents an improvement in measurement precision and does not create compatibility issues. Existing system calibration and signal processing will function with the enhanced accuracy.

Q: Are there any electrical circuit modifications required?

A: No. Both sensors output identical Wheatstone Bridge signals (0 mV ~ 25 mV at 12V). The substitute part operates at a fixed 16V supply, which is within the original device's rated supply range (3V ~ 16V). Existing signal conditioning and measurement circuits require no modification.

Q: How do the port style differences affect installation?

A: The CPCL04GFC uses a barbed male connector (0.15" tube), while the 4 INCH-GF-CGRADE-MINI uses a barbless male connector (0.18" tube). Barbed connectors rely on barbs to grip tubing; barbless connectors typically require compression fittings or push-to-connect adapters. Verify that your tubing and connector hardware are compatible with the 0.18" diameter and barbless design.

Q: Is the substitute part currently available?

A: Yes. The 4 INCH-GF-CGRADE-MINI is classified as active product status and is currently manufactured by Amphenol All Sensors Corporation, ensuring ongoing availability and supply chain support.

Q: What is the difference between the CPCL series and the ACPC series?

A: The CPCL04GFC belongs to the CPCL series (Honeywell). The substitute 4 INCH-GF-CGRADE-MINI belongs to the ACPC series (Amphenol All Sensors). Both series provide equivalent vented gauge pressure sensors with Wheatstone Bridge output for low-pressure applications. The series designation reflects different manufacturers and product lines.

Q: Are both parts RoHS compliant?

A: Yes. Both the CPCL04GFC and 4 INCH-GF-CGRADE-MINI are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
