Equivalent & Substitute Parts: CPC01DFH

Part Overview

The CPC01DFH is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 1PSI (6.89kPa) operating pressure range. The sensor features a Wheatstone Bridge output configuration with dual barbed male ports (0.16" tube diameter) and operates across a supply voltage range of 3V to 16V, delivering 0 mV to 18 mV output at 12V.

This part is classified as obsolete. Locating equivalent substitute components is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC01DFH is determined by the following critical parameters:

Pressure Compatibility: The operating pressure range must accommodate the 1PSI (6.89kPa) differential specification. Substitute parts must support this pressure range within their maximum pressure rating.

Output Configuration: The Wheatstone Bridge output type is a fundamental functional requirement. Substitute sensors must maintain this output topology to ensure circuit compatibility.

Package and Termination: The 4-SIP module package with PC pin termination and through-hole mounting must be preserved to maintain PCB compatibility without redesign.

Port Interface: Dual barbed male ports are required for pneumatic connection. Port diameter variations are acceptable if mechanical adapters are available, but port style and configuration must remain consistent.

Electrical Characteristics: Supply voltage range and output voltage specifications must overlap with the original design operating window. Temperature compensation is a required feature.

Compliance: RoHS compliance status must be maintained for regulatory adherence.

The substitute part TSCSAAN001PDUCV meets these criteria while offering improved specifications in accuracy and pressure range.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TSCSAAN001PDUCV is the qualified equivalent for CPC01DFH replacement applications.

Justification:

Both sensors are manufactured by Honeywell Sensing and Productivity Solutions and share identical output topology (Wheatstone Bridge), package format (4-SIP), and termination style (PC pin through-hole). Both are RoHS compliant and temperature compensated.

The TSCSAAN001PDUCV offers superior specifications: accuracy of ±0.2% compared to ±2%, extended maximum pressure rating of ±12.5PSI versus 5PSI, and expanded operating temperature range of -40°C to 85°C versus -25°C to 85°C. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity.

Design Considerations:

The TSCSAAN001PDUCV operates at 5V nominal output versus the CPC01DFH's 12V nominal output. The supply voltage range of 1.5V to 12V overlaps with the original 3V to 16V specification within the 1.5V to 12V window. Signal conditioning circuits must be verified to accommodate the 0 mV to 15 mV output range instead of 0 mV to 18 mV.

Port configuration differs: the substitute features dual ports on opposite sides versus same-side configuration on the original. Mechanical integration must account for this dimensional change. Port diameter increases from 0.16" (4.06mm) to 0.19" (4.93mm), requiring verification of tubing compatibility or adapter availability.

Both parts are classified as MSL 1 (Unlimited moisture sensitivity), eliminating moisture-related handling concerns.

Frequently Asked Questions (FAQ)

Q: Can TSCSAAN001PDUCV directly replace CPC01DFH without circuit modification?

A: Functional substitution is possible with signal conditioning adjustments. The output voltage range differs (15 mV versus 18 mV at nominal supply), and the nominal supply voltage is lower (5V versus 12V). Analog signal processing circuits must be recalibrated to accommodate these differences. Mechanical port configuration and diameter changes require integration verification.

Q: What is the impact of the port configuration change from same-side to opposite-side?

A: Port placement on opposite sides affects PCB layout and tubing routing. The 0.19" (4.93mm) port diameter on the substitute is larger than the original 0.16" (4.06mm). Existing tubing connections may require adapters or replacement. Mechanical clearance around the sensor must be re-evaluated during integration.

Q: Is the accuracy improvement from ±2% to ±0.2% significant for this application?

A: Accuracy improvement is a specification enhancement. If the original design operated within ±2% tolerance margins, the substitute's ±0.2% accuracy provides additional measurement precision. System calibration procedures should be reviewed to leverage this improvement.

Q: Are both parts RoHS compliant?

A: Yes. Both CPC01DFH and TSCSAAN001PDUCV are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, meeting regulatory requirements for electronics manufacturing.

Q: What is the supply voltage compatibility window?

A: The CPC01DFH operates at 3V to 16V; the TSCSAAN001PDUCV operates at 1.5V to 12V. The overlapping range is 3V to 12V. If the original design supplies voltage above 12V, the substitute cannot be used without power supply modification.

Q: Why is the CPC01DFH obsolete?

A: The CPC01DFH is classified as obsolete by the manufacturer. The TSCSAAN001PDUCV from the active TruStability® TSC series represents the current generation equivalent, offering improved specifications and guaranteed long-term availability.
