Equivalent & Substitute Parts for CPC0.3GFC Pressure Sensor

Part Overview

The CPC0.3GFC is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement up to 0.3 PSI (2.07 kPa). This sensor features a Wheatstone Bridge output with 0 mV to 20 mV signal range at 12V supply, temperature compensation, and through-hole mounting in a 4-SIP module package.

The CPC0.3GFC 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 CPC0.3GFC is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Operating Pressure: 0.3 PSI (2.07 kPa) nominal rating
• Pressure Type: Vented Gauge configuration
• Output Type: Wheatstone Bridge signal conditioning
• Output Signal Range: 0 mV ~ 20 mV at 12V supply
• Package Type: 4-SIP Module form factor
• Mounting Type: Through Hole
• Temperature Compensation: Required feature
• Operating Temperature Range: -25°C ~ 85°C minimum coverage

Secondary Compatibility Factors:

• Supply Voltage: Minimum 12V operation capability within specified range
• RoHS Compliance: Required for regulatory alignment
• Port Configuration: Male barbed or equivalent connection style

The substitute part 0.3 PSI-GF-CGRADE-MINI (Amphenol All Sensors Corporation) meets these criteria with documented equivalence in pressure rating, output characteristics, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The 0.3 PSI-GF-CGRADE-MINI from Amphenol All Sensors Corporation qualifies as a functional equivalent to the obsolete CPC0.3GFC based on matching pressure rating, output characteristics, package configuration, and operating specifications.

Selection Basis:

1. Product Status Alignment: The substitute part maintains active manufacturing status, ensuring long-term supply availability and support compared to the obsolete CPC0.3GFC.

2. Regulatory Compliance: Both parts maintain RoHS Compliant certification, satisfying environmental and regulatory requirements for equivalent component substitution.

3. Electrical Compatibility: Identical Wheatstone Bridge output type and 0 mV to 20 mV signal range at 12V supply ensure direct signal compatibility with existing circuit designs and signal conditioning electronics.

4. Mechanical Compatibility: Both sensors utilize 4-SIP Module packaging with through-hole mounting, supporting direct PCB integration without redesign of mounting infrastructure.

5. Performance Characteristics: The substitute part delivers ±1% accuracy compared to the original ±2%, representing improved measurement precision while maintaining all other functional parameters.

Design Considerations:

Port configuration differences exist between the two sensors. The CPC0.3GFC features a 0.16" (4.06 mm) barbed male tube connection, while the 0.3 PSI-GF-CGRADE-MINI provides a 0.18" (4.57 mm) barbless male tube connection. These differences require evaluation of existing tubing interfaces and connection methodology in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 0.3 PSI-GF-CGRADE-MINI directly replace the CPC0.3GFC without circuit modifications?

A: Yes, for signal processing and electrical integration. Both sensors provide identical Wheatstone Bridge output with 0 mV to 20 mV range at 12V supply. However, the port connection style differs (barbed versus barbless), requiring assessment of tubing compatibility and connection method in your specific application.

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

A: The 0.02" (0.51 mm) difference in tube diameter represents a minor variation in the barbed connection interface. Existing tubing sized for 0.16" barbed connections may require adjustment or replacement to accommodate the 0.18" barbless connection of the substitute part. Verify tubing specifications and connection requirements before implementation.

Q: Why does the substitute part specify 16V supply voltage while the original supports 3V to 16V?

A: The CPC0.3GFC supports a wider supply voltage range (3V to 16V), while the 0.3 PSI-GF-CGRADE-MINI is specified at 16V. Both sensors operate at 12V, which falls within the original part's range and matches the substitute's specification. If your application requires operation below 16V, verify that the substitute part's fixed 16V specification aligns with your power supply design.

Q: Is the improved accuracy (±1% versus ±2%) a concern for substitution?

A: No. The substitute part's ±1% accuracy represents improved performance compared to the original ±2% specification. This enhanced accuracy does not create compatibility issues and may benefit measurement precision in your application.

Q: What is the MSL (Moisture Sensitivity Level) rating for both parts?

A: Both the CPC0.3GFC and 0.3 PSI-GF-CGRADE-MINI carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the CPC0.3GFC and 0.3 PSI-GF-CGRADE-MINI are RoHS Compliant, meeting environmental and regulatory requirements for equivalent component substitution in regulated applications.

Q: What is the maximum pressure rating difference between these sensors?

A: The CPC0.3GFC has a maximum pressure rating of 5 PSI (34.47 kPa), while the 0.3 PSI-GF-CGRADE-MINI is rated to 3 PSI (20.68 kPa). Both sensors are designed for 0.3 PSI nominal operation. The lower maximum rating of the substitute part does not affect performance at the 0.3 PSI operating point but indicates a narrower overpressure margin.
