CPCL04GC Pressure Sensor Equivalent & Substitute Parts

Part Overview

The CPCL04GC is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. It operates in the 0.15PSI (1kPa) range with a Wheatstone Bridge output of 0–25 mV at 12V supply. The device is designed for board-mount applications requiring temperature-compensated pressure measurement in industrial and embedded systems.

The CPCL04GC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPCL04GC is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure of 0.15PSI (1kPa), vented gauge type, and maximum pressure rating of 3PSI (20.68kPa) must be maintained.

Electrical Characteristics: Wheatstone Bridge output topology with 0–25 mV signal range at 12V supply voltage. Supply voltage compatibility within the 3V–16V range is required.

Mechanical Compatibility: 4-SIP Module package, through-hole mounting, and no-port configuration ensure direct PCB integration without redesign.

Environmental Performance: Temperature compensation and operating range of −25°C to +85°C must be preserved.

Regulatory Compliance: RoHS compliance and EAR99 classification must be maintained.

The substitute part identified below meets all these criteria while offering improved product status and availability.

Parameter Comparison

Engineering Selection Recommendations

The 4 INCH-G-CGRADE-MINI from Amphenol All Sensors Corporation is a direct functional equivalent to the CPCL04GC. Both devices share identical pressure specifications, electrical output characteristics, mechanical form factor, and environmental operating parameters.

Product Status Advantage: The substitute part maintains active production status, ensuring long-term supply chain availability and support compared to the obsolete CPCL04GC.

Performance Improvement: The 4 INCH-G-CGRADE-MINI offers enhanced accuracy of ±1% versus the CPCL04GC's ±2%, providing tighter measurement tolerance without requiring circuit modifications.

Regulatory Compliance: Both parts are RoHS compliant and classified under ECCN EAR99, maintaining regulatory alignment for existing applications.

Voltage Supply Consideration: The substitute part specifies 16V supply voltage, which falls within the CPCL04GC's 3V–16V range. Applications operating at the lower end of the original voltage range (below 16V) require verification that the substitute part's fixed 16V specification is compatible with the power supply design.

Packaging Format: The substitute is supplied in tube packaging versus bulk, which may affect procurement and handling procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 4 INCH-G-CGRADE-MINI replace the CPCL04GC in existing designs without PCB modifications?

A: Yes. Both parts use identical 4-SIP Module packaging with through-hole mounting and no-port configuration. Pin-to-pin compatibility is maintained, allowing direct substitution on existing PCBs.

Q: What is the difference in accuracy between these two sensors?

A: The CPCL04GC provides ±2% accuracy, while the 4 INCH-G-CGRADE-MINI provides ±1% accuracy. The substitute offers improved measurement precision. Both accuracies are specified across the operating temperature range.

Q: Are there voltage supply differences I need to address?

A: The CPCL04GC accepts 3V–16V supply voltage. The 4 INCH-G-CGRADE-MINI is specified for 16V supply. If your application uses a supply voltage below 16V, confirm that the substitute part operates correctly at your specific supply voltage before implementation.

Q: Do both sensors have the same output signal characteristics?

A: Yes. Both sensors provide Wheatstone Bridge output with 0–25 mV signal range at 12V supply. Signal conditioning and interface circuits require no modification.

Q: What is the significance of the "vented gauge" pressure type?

A: Vented gauge configuration means the sensor measures pressure relative to atmospheric pressure through a vent port. Both the CPCL04GC and 4 INCH-G-CGRADE-MINI use this configuration, ensuring identical pressure measurement behavior in the application.

Q: Are both parts temperature compensated?

A: Yes. Both sensors include temperature compensation and operate across −25°C to +85°C. Temperature-related drift is managed internally in both devices.

Q: What is the difference in packaging format?

A: The CPCL04GC is supplied in bulk packaging, while the 4 INCH-G-CGRADE-MINI is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the CPCL04GC and 4 INCH-G-CGRADE-MINI are RoHS compliant and classified under ECCN EAR99, maintaining regulatory requirements for restricted substance use and export control.
