CPC15DFC Equivalent & Substitute Parts

Part Overview

The CPC15DFC is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 15 PSI (103.42 kPa) differential pressure measurement. The sensor outputs a Wheatstone Bridge signal of 0 mV to 90 mV at 12V supply voltage and features temperature compensation across an operating range of -25°C to 85°C.

The CPC15DFC is classified as obsolete. Identifying equivalent and 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 CPC15DFC is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Pressure Type: Differential
• Operating Pressure: 15 PSI (103.42 kPa)
• Output Type: Wheatstone Bridge
• Output Signal: 0 mV ~ 90 mV (12V)
• Package Type: 4-SIP Module
• Mounting Type: Through Hole
• Temperature Compensation: Required

Allowable Variation Parameters:

• Accuracy: May improve (lower tolerance value acceptable)
• Voltage Supply Range: May expand (wider range acceptable)
• Maximum Pressure: May increase (higher rating acceptable)
• Port Size: Minor dimensional variation acceptable within mechanical compatibility constraints
• Port Style: Barbed or barbless both acceptable for functional equivalence

The substitute part 15 PSI-D-CGRADE-MINI manufactured by Amphenol All Sensors Corporation meets all mandatory equivalence parameters and demonstrates improvements in accuracy (±1% versus ±2%) and maximum pressure rating (60 PSI versus 45 PSI).

Parameter Comparison

Engineering Selection Recommendations

The 15 PSI-D-CGRADE-MINI from Amphenol All Sensors Corporation is a functional equivalent to the obsolete CPC15DFC. Selection of this substitute is supported by the following engineering factors:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete CPC15DFC.

Compliance: Both parts maintain RoHS compliance and identical ECCN/HTSUS classifications, supporting regulatory and export requirements without modification.

Performance Characteristics: The substitute demonstrates equivalent or superior performance across all critical parameters. The improved accuracy specification (±1% versus ±2%) and higher maximum pressure rating (60 PSI versus 45 PSI) provide enhanced measurement precision and safety margin without compromising functional compatibility.

Mechanical Compatibility: Port configuration differences (0.18" barbless versus 0.16" barbed) require mechanical interface verification during integration. Tubing adapter compatibility must be confirmed for specific application requirements.

Electrical Compatibility: Voltage supply specification for the substitute (16V fixed) is within the operating range of the original part (3V ~ 16V). System power supply design must confirm 16V availability.

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-D-CGRADE-MINI directly replace the CPC15DFC without circuit modifications?

A: Electrical compatibility is confirmed. Both sensors output identical Wheatstone Bridge signals (0 mV ~ 90 mV at 12V) with identical 4-SIP pinout and through-hole mounting. No circuit modifications are required. Mechanical interface verification is necessary due to port size and style differences (0.18" barbless versus 0.16" barbed).

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

A: The port size difference represents a 0.02" (0.51 mm) increase in tube diameter. This requires verification of tubing compatibility and adapter requirements for the specific application. Barbed versus barbless port styles may affect tubing retention characteristics and require different connection methods.

Q: Is the improved accuracy (±1% versus ±2%) significant for my application?

A: Accuracy improvement depends on application requirements. The substitute provides tighter measurement tolerance, which may benefit high-precision applications. For applications where ±2% accuracy is sufficient, both parts are functionally equivalent.

Q: Does the higher maximum pressure rating (60 PSI versus 45 PSI) affect sensor selection?

A: The higher maximum pressure rating provides additional safety margin and overpressure protection. This does not negatively impact applications designed for 15 PSI operation and represents an engineering advantage.

Q: Are there supply chain considerations for the substitute part?

A: The 15 PSI-D-CGRADE-MINI maintains active production status with documented inventory availability (737 pieces in stock). The CPC15DFC is obsolete with limited remaining inventory (940 pieces). Active production status ensures long-term availability for ongoing requirements.

Q: What certifications and compliance standards apply to both parts?

A: Both parts maintain RoHS compliance and identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications. Regulatory and export requirements are equivalent between the two parts.
