Equivalent & Substitute Parts for CPC05DFC Pressure Sensor

Part Overview

The CPC05DFC is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 5 PSI (34.47 kPa) differential pressure measurement. The sensor outputs a Wheatstone Bridge signal of 0 mV to 60 mV at 12V supply voltage and features temperature compensation across an operating range of -25°C to 85°C.

The CPC05DFC 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 CPC05DFC is determined by the following critical parameters:

Primary Matching Criteria:

• Pressure Type: Differential
• Operating Pressure: 5 PSI (34.47 kPa)
• Output Type: Wheatstone Bridge
• Output Signal: 0 mV ~ 60 mV (12V)
• Mounting Type: Through Hole
• Package Type: 4-SIP Module
• Operating Temperature Range: -25°C ~ 85°C

Secondary Compatibility Factors:

• Voltage Supply Range: Must accommodate 12V nominal operation
• Port Style: Barbed or equivalent mechanical interface
• Termination Style: PC Pin
• Temperature Compensation: Required

The substitute part 5 PSI-D-CGRADE-MINI manufactured by Amphenol All Sensors Corporation satisfies all primary matching criteria. Variations in port size (0.18" versus 0.16"), accuracy specification (±1% versus ±2%), and maximum pressure rating (20 PSI versus 15 PSI) represent acceptable engineering tolerances within the differential pressure sensor category and do not preclude functional substitution.

Parameter Comparison

Engineering Selection Recommendations

CPC05DFC (Honeywell): This part is classified as obsolete. While 884 pieces remain in current inventory, long-term availability cannot be assured. Selection of this part is appropriate only for immediate replacement needs or legacy system maintenance where no design modifications are permissible.

5 PSI-D-CGRADE-MINI (Amphenol All Sensors): This part is classified as active with 988 pieces in current inventory. It satisfies all functional requirements of the CPC05DFC and offers improved accuracy (±1% versus ±2%) and higher maximum pressure rating (20 PSI versus 15 PSI). Both parts are RoHS Compliant and carry identical ECCN and HTSUS classifications. The Amphenol part is the preferred selection for new designs, redesigns, or ongoing production requiring supply chain continuity.

Mechanical Interface Consideration: The port size difference (0.18" versus 0.16") and port style variation (barbless versus barbed) require verification of tubing compatibility in the target application. Tubing inner diameter and connection method must be confirmed before final component selection.

Frequently Asked Questions (FAQ)

Q: Can the 5 PSI-D-CGRADE-MINI directly replace the CPC05DFC without circuit modifications?

A: Both sensors output identical Wheatstone Bridge signals (0 mV ~ 60 mV at 12V) and operate across the same temperature range (-25°C ~ 85°C). Circuit-level compatibility is established. Mechanical interface compatibility (tubing connection) must be verified independently.

Q: What is the significance of the port size difference (0.16" versus 0.18")?

A: Port size affects tubing compatibility. The CPC05DFC uses 0.16" (4.06 mm) barbed ports, while the 5 PSI-D-CGRADE-MINI uses 0.18" (4.57 mm) barbless ports. Tubing inner diameter and connection method must match the selected sensor. Adapter fittings may be required if existing tubing is sized for the original part.

Q: Why does the 5 PSI-D-CGRADE-MINI specify 16V supply while the CPC05DFC specifies 3V ~ 16V?

A: The Amphenol part is rated for 16V nominal supply. The Honeywell part accepts a wider supply range (3V ~ 16V). Both sensors operate correctly at 12V, which is the standard operating voltage for the Wheatstone Bridge output specification. The narrower specification for the Amphenol part does not preclude substitution in 12V applications.

Q: What does the ±1% accuracy improvement in the 5 PSI-D-CGRADE-MINI mean for system performance?

A: The Amphenol part provides tighter accuracy tolerance (±1% versus ±2%), resulting in reduced measurement uncertainty. For a 5 PSI sensor, this represents approximately 0.05 PSI versus 0.10 PSI maximum error. This improvement is beneficial but not required for substitution compatibility.

Q: Are both parts RoHS Compliant?

A: Yes. Both the CPC05DFC and 5 PSI-D-CGRADE-MINI are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications.

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

A: Barbed ports (CPC05DFC) grip tubing mechanically through barb engagement. Barbless ports (5 PSI-D-CGRADE-MINI) require alternative retention methods such as hose clamps or compression fittings. Port style selection depends on the tubing connection method specified in the target application.
