CPC15AFH Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The CPC15AFH is a 15 PSI absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This device operates as a Wheatstone Bridge output sensor with a barbed male tube connection (0.15" / 3.8mm) and delivers 0 mV to 90 mV output at 12V supply. The sensor is mounted through-hole in a 4-SIP module package and includes temperature compensation across an operating range of -25°C to 85°C.

The CPC15AFH is classified as obsolete. Equivalent substitute parts are available from Amphenol All Sensors Corporation within the ACPC series, which maintain functional compatibility while offering improved accuracy specifications and active product status.

Mounting type: Through hole, 4-SIP module
Operating temperature range: -25°C ~ 85°C

Termination style: PC pin
RoHS compliance: Yes

Allowable Variations:

Port size: 0.18" (4.57mm) tube versus 0.15" (3.8mm) tube (minor dimensional difference)
Port style: Barbless versus barbed (functional equivalence for pressure containment)
Supply voltage: 16V fixed versus 3V ~ 16V range (substitute operates within original range)
Maximum pressure: 60 PSI (413.69 kPa) versus 45 PSI (higher safety margin)
Accuracy: ±0.3% to ±1% versus ±2% (improved performance)

Three substitute part numbers are available, differentiated by accuracy grade: 15 PSI-AF-PRIME-MINI (±0.3%), 15 PSI-AF-HGRADE-MINI (±0.5%), and 15 PSI-AF-CGRADE-MINI (±1%).

Engineering Selection Recommendations

Product Status Consideration: The CPC15AFH is obsolete. All three Amphenol All Sensors Corporation substitute parts (15 PSI-AF-PRIME-MINI, 15 PSI-AF-HGRADE-MINI, 15 PSI-AF-CGRADE-MINI) maintain active product status, ensuring long-term availability and supply chain continuity.

Compliance and Certification: All substitute parts maintain RoHS compliance and MSL rating 1 (unlimited moisture sensitivity level), matching the original CPC15AFH specifications. ECCN and HTSUS classifications remain consistent across all parts.

Accuracy Grade Selection:

15 PSI-AF-PRIME-MINI (±0.3%): Select for applications requiring highest measurement precision and tightest tolerance control.
15 PSI-AF-HGRADE-MINI (±0.5%): Select for applications requiring improved accuracy over the original ±2% specification with balanced cost considerations.
15 PSI-AF-CGRADE-MINI (±1%): Select for applications where the original ±2% accuracy is acceptable and cost optimization is prioritized.

Port Connection Compatibility: The substitute parts feature a 0.18" (4.57mm) barbless male tube connection compared to the original 0.15" (3.8mm) barbed connection. Tubing compatibility must be verified for the specific application. The barbless design provides equivalent pressure containment functionality.

Voltage Supply: Substitute parts operate at fixed 16V supply, which falls within the original 3V ~ 16V range. Applications using the full 3V ~ 16V range of the CPC15AFH must confirm 16V operation is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-AF-PRIME-MINI, 15 PSI-AF-HGRADE-MINI, and 15 PSI-AF-CGRADE-MINI be used interchangeably with the CPC15AFH?

A: Yes, all three Amphenol All Sensors Corporation parts are functionally equivalent substitutes for the CPC15AFH. They share identical pressure ratings, output types, output ranges, mounting configurations, and operating temperature ranges. Selection between the three grades depends on accuracy requirements for the specific application.

Q: What is the difference between the three substitute part numbers?

A: The three substitute parts differ only in accuracy specification: 15 PSI-AF-PRIME-MINI provides ±0.3% accuracy, 15 PSI-AF-HGRADE-MINI provides ±0.5% accuracy, and 15 PSI-AF-CGRADE-MINI provides ±1% accuracy. All other electrical and mechanical parameters are identical.

Q: Does the port size difference (0.15" versus 0.18") affect substitution?

A: The port size difference requires verification of tubing compatibility in the specific application. The 0.18" (4.57mm) tube connection of the substitute parts is slightly larger than the original 0.15" (3.8mm) connection. Tubing adapters or replacement may be necessary depending on the existing pneumatic or hydraulic system configuration.

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

A: Both barbed and barbless port styles provide pressure-tight connections to tubing. The barbed design uses mechanical retention through barbs on the connector; the barbless design relies on compression fitting. Both are functionally equivalent for pressure containment. Tubing compatibility must be verified for the specific application.

Q: Can the CPC15AFH operate at voltages below 16V if substituted with the Amphenol parts?

A: The substitute parts are specified for 16V fixed supply voltage, whereas the original CPC15AFH operates across 3V ~ 16V. Applications requiring operation below 16V must confirm that 16V operation is acceptable for the system design.

Q: Are all parts RoHS compliant?

A: Yes, the CPC15AFH and all three substitute parts are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the inventory status of these parts?

A: The CPC15AFH has 1,308 pieces in stock (obsolete status). The substitute parts have active status with the following inventory: 15 PSI-AF-PRIME-MINI (1,116 pieces), 15 PSI-AF-HGRADE-MINI (966 pieces), and 15 PSI-AF-CGRADE-MINI (958 pieces).
