CPC15AC Pressure Sensor Equivalent & Substitute Parts

Part Overview

The CPC15AC is an absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 15 PSI (103.42 kPa) absolute pressure measurement. The sensor outputs a Wheatstone Bridge signal of 0 mV to 90 mV at 12V supply voltage with ±2% accuracy and temperature compensation across the -25°C to 85°C operating range.

The CPC15AC 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 eligibility for the CPC15AC is determined by the following critical parameters:

Pressure Specification: The substitute must measure 15 PSI (103.42 kPa) absolute pressure. This is the primary functional requirement.

Output Characteristics: The substitute must provide a Wheatstone Bridge output signal of 0 mV to 90 mV at 12V supply voltage to ensure signal compatibility with existing signal conditioning circuits.

Electrical Interface: The substitute must operate within the 3V to 16V supply voltage range and maintain output specifications across this range.

Mechanical Compatibility: The substitute must use Through Hole mounting and a 4-SIP Module package to ensure physical compatibility with existing printed circuit board layouts.

Environmental Performance: The substitute must maintain specified accuracy and output characteristics across the -25°C to 85°C operating temperature range with temperature compensation.

Regulatory Compliance: The substitute must maintain RoHS Compliance and MSL 1 (Unlimited) moisture sensitivity rating.

The 15 PSI-A-CGRADE-MINI from Amphenol All Sensors Corporation meets all critical substitution criteria.

Engineering Selection Recommendations

The 15 PSI-A-CGRADE-MINI is a direct functional equivalent to the CPC15AC for applications requiring 15 PSI absolute pressure measurement with Wheatstone Bridge output.

Supply Voltage Consideration: The CPC15AC operates across 3V to 16V, while the 15 PSI-A-CGRADE-MINI is specified at 16V. Systems operating the original sensor at voltages below 16V must verify that the substitute performs within specification at the intended supply voltage.

Accuracy Enhancement: The 15 PSI-A-CGRADE-MINI provides ±1% accuracy compared to the CPC15AC's ±2% accuracy, representing improved measurement precision without requiring circuit modifications.

Pressure Margin: The 15 PSI-A-CGRADE-MINI has a maximum pressure rating of ±60 PSI compared to the CPC15AC's 45 PSI, providing additional overpressure protection margin.

Regulatory Status: Both sensors maintain RoHS Compliance and MSL 1 ratings. The 15 PSI-A-CGRADE-MINI is currently in active production status, ensuring long-term availability and supply chain continuity.

Packaging: Both sensors use identical 4-SIP Module through-hole packages, permitting direct physical substitution on existing printed circuit boards without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-A-CGRADE-MINI directly replace the CPC15AC on existing circuit boards?

A: Yes. Both sensors use identical 4-SIP Module through-hole packages with the same pin configuration and spacing. Physical substitution requires no printed circuit board modifications.

Q: Are the output signals identical between these sensors?

A: Both sensors provide 0 mV to 90 mV Wheatstone Bridge output at 12V supply voltage. Signal conditioning circuits designed for the CPC15AC will function with the 15 PSI-A-CGRADE-MINI without modification.

Q: What is the difference in supply voltage specifications?

A: The CPC15AC operates across 3V to 16V, while the 15 PSI-A-CGRADE-MINI is specified at 16V. Applications using supply voltages below 16V must confirm the substitute operates within specification at the intended voltage before implementation.

Q: Does the improved accuracy of the 15 PSI-A-CGRADE-MINI require circuit recalibration?

A: The ±1% accuracy of the 15 PSI-A-CGRADE-MINI is superior to the CPC15AC's ±2% accuracy. Existing signal conditioning and calibration circuits will function correctly with the substitute. System-level accuracy may improve without requiring modifications.

Q: Are both sensors temperature compensated?

A: Yes. Both the CPC15AC and 15 PSI-A-CGRADE-MINI include temperature compensation and maintain specified performance across the -25°C to 85°C operating temperature range.

Q: What is the availability status of the substitute part?

A: The 15 PSI-A-CGRADE-MINI is in active production status. The CPC15AC is obsolete. Transitioning to the substitute ensures continued supply chain access and long-term component availability.

Q: Are there any regulatory or compliance differences?

A: Both sensors are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity ratings. No compliance differences exist between the two parts.
