Equivalent & Substitute Parts for Honeywell CPC0.3GFH Pressure Sensor

Part Overview

The Honeywell CPC0.3GFH is a vented gauge pressure sensor designed for low-pressure applications requiring 0.3 PSI (2.07 kPa) measurement capability. This sensor features a Wheatstone Bridge output with 0 mV to 20 mV signal range at 12V supply, temperature compensation, and through-hole PC pin termination for board-mount applications.

The CPC0.3GFH is classified as an obsolete product. 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 CPC0.3GFH is determined by the following critical parameters:

Primary Matching Criteria:

• Operating pressure rating of 0.3 PSI (2.07 kPa)
• Vented gauge pressure type
• Wheatstone Bridge output configuration
• Output signal range of 0 mV ~ 20 mV at 12V supply
• 4-SIP module package format
• PC pin through-hole termination
• Temperature compensation feature
• Operating temperature range of -25°C ~ 85°C

Secondary Compatibility Factors:

• Supply voltage compatibility within the 3V ~ 16V range
• Port style and size (barbed or barbless male tube configurations)
• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The Amphenol All Sensors Corporation part number 0.3 PSI-GF-HGRADE-MINI qualifies as a direct substitute based on matching all primary criteria. Variations in port size (0.15" versus 0.18" tube diameter) and port style (barbed versus barbless) represent mechanical interface differences that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol All Sensors Corporation 0.3 PSI-GF-HGRADE-MINI is an active product with current manufacturing support, making it the primary substitute for the obsolete Honeywell CPC0.3GFH.

Compliance and Certification Alignment: Both parts maintain RoHS compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with existing design standards. The Amphenol substitute carries REACH Unaffected status, providing additional regulatory clarity for international applications.

Performance Considerations: The Amphenol substitute provides improved accuracy (±0.5% versus ±2%), representing enhanced measurement precision. The substitute operates at a fixed 16V supply voltage rather than the CPC0.3GFH's 3V to 16V range. Applications requiring variable supply voltage operation must verify compatibility with the fixed 16V requirement.

Mechanical Interface Differences: The port size increases from 0.15" (3.8mm) to 0.18" (4.57mm) tube diameter, and the port style changes from barbed to barbless configuration. These mechanical differences require evaluation of tubing compatibility and connection method within the specific application. Maximum pressure rating decreases from 5 PSI to 3 PSI, which is acceptable for 0.3 PSI operating pressure applications with standard safety margins.

Supply Chain Status: The Amphenol substitute is available in active production with documented inventory, supporting immediate procurement and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol 0.3 PSI-GF-HGRADE-MINI directly replace the Honeywell CPC0.3GFH without circuit modifications?

A: The electrical interface is compatible. Both sensors provide identical Wheatstone Bridge output at 0 mV to 20 mV (12V). The Amphenol part operates at fixed 16V supply, which falls within the CPC0.3GFH's 3V to 16V range. Existing signal conditioning circuits designed for the Honeywell sensor will function with the Amphenol substitute. Mechanical tubing connections require evaluation due to port size and style differences.

Q: What are the mechanical interface differences between these two sensors?

A: The Honeywell CPC0.3GFH features a 0.15" (3.8mm) barbed male tube port, while the Amphenol 0.3 PSI-GF-HGRADE-MINI has a 0.18" (4.57mm) barbless male tube port. Barbed ports create mechanical retention through tubing deformation, while barbless ports rely on tubing compression or secondary fastening. Tubing diameter compatibility must be verified for the specific application.

Q: How do the accuracy specifications compare?

A: The Honeywell CPC0.3GFH specifies ±2% accuracy, while the Amphenol substitute provides ±0.5% accuracy. The Amphenol sensor delivers improved measurement precision. For applications where the original ±2% accuracy is a design requirement, the enhanced ±0.5% accuracy of the substitute is acceptable and provides additional performance margin.

Q: Are there supply voltage compatibility concerns?

A: The Honeywell CPC0.3GFH accepts 3V to 16V supply voltage. The Amphenol substitute operates at fixed 16V. If the application circuit provides variable supply voltage between 3V and 16V, the fixed 16V requirement of the Amphenol sensor must be accommodated through circuit design or voltage regulation. At 16V operation, both sensors produce identical 0 mV to 20 mV output range.

Q: What is the significance of the maximum pressure rating difference?

A: The Honeywell CPC0.3GFH has a 5 PSI maximum pressure rating, while the Amphenol substitute is rated to 3 PSI. Both sensors operate at 0.3 PSI nominal pressure. The 3 PSI maximum rating of the Amphenol sensor provides adequate overpressure protection for typical 0.3 PSI applications with standard safety margins. Applications requiring higher overpressure protection must evaluate this specification against system requirements.

Q: Are both sensors RoHS compliant?

A: Yes. Both the Honeywell CPC0.3GFH and Amphenol 0.3 PSI-GF-HGRADE-MINI are RoHS compliant. The Amphenol substitute additionally carries REACH Unaffected status, providing regulatory clarity for European and international markets.

Q: What is the packaging and inventory status?

A: The Honeywell CPC0.3GFH is obsolete with 914 pieces available in current inventory. The Amphenol 0.3 PSI-GF-HGRADE-MINI is an active product with 805 pieces in current inventory and ongoing manufacturing support, ensuring long-term availability for future production requirements.
