CPC01GFH Pressure Sensor Equivalent & Substitute Parts

Part Overview

The CPC01GFH is a 1PSI vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component features a Wheatstone Bridge output with 0 mV to 18 mV signal range at 12V supply, designed for board mount applications with through-hole termination. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility across critical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC01GFH is determined by strict equivalence across the following parameters: operating pressure rating (1PSI), pressure type (vented gauge), output type (Wheatstone Bridge), output signal range (0 mV ~ 18 mV at 12V), package configuration (4-SIP Module), termination style (PC Pin), mounting type (through hole), and operating temperature range (-25°C ~ 85°C).

The three substitute parts listed—1 PSI-GF-PRIME-MINI, 1 PSI-GF-CGRADE-MINI, and 1 PSI-GF-HGRADE-MINI—are manufactured by Amphenol All Sensors Corporation under the ACPC series. All three maintain identical pressure ratings, output characteristics, package types, and thermal operating ranges as the original CPC01GFH. These substitutes are classified as active products, ensuring ongoing availability and supply chain continuity.

Differences between substitute options are limited to accuracy specifications, supply voltage fixed point, port tube diameter, port style configuration, maximum pressure rating, and regulatory compliance status. These variations do not affect functional substitution capability within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

All three Amphenol All Sensors Corporation substitutes maintain functional equivalence to the CPC01GFH across core pressure sensing parameters. Selection between substitute options should be based on regulatory compliance requirements and accuracy specifications.

1 PSI-GF-PRIME-MINI is recommended for applications requiring highest accuracy performance (±0.25%) and RoHS compliance certification. This part is suitable for precision measurement applications where signal fidelity is critical.

1 PSI-GF-CGRADE-MINI provides balanced accuracy (±1%) with full RoHS compliance, offering cost-effective substitution for general industrial applications where moderate accuracy is acceptable.

1 PSI-GF-HGRADE-MINI delivers intermediate accuracy (±0.5%) but carries RoHS non-compliant status. This option is applicable only in applications where RoHS compliance is not mandated by design or regulatory requirements.

All substitutes feature improved maximum pressure ratings (10PSI versus 5PSI) and fixed 16V supply voltage specification compared to the original CPC01GFH. Port tube diameter increases from 0.15" to 0.18" and port style changes from barbed to barbless configuration; tubing interface compatibility must be verified during integration.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol substitutes directly replace the CPC01GFH without circuit modifications?

A: Electrical substitution is direct. Both the original and substitute parts output 0 mV to 18 mV signal range at 12V supply with identical Wheatstone Bridge output type and 4-SIP module package. However, the supply voltage specification differs: CPC01GFH accepts 3V to 16V, while Amphenol substitutes are fixed at 16V. Verify that your circuit supplies exactly 16V to the substitute part. Additionally, port tube diameter and style differ (0.15" barbed versus 0.18" barbless), requiring tubing interface verification.

Q: What is the difference between the three Amphenol substitute options?

A: The three parts differ in accuracy specification and regulatory compliance. 1 PSI-GF-PRIME-MINI offers ±0.25% accuracy with RoHS compliance. 1 PSI-GF-CGRADE-MINI provides ±1% accuracy with RoHS compliance. 1 PSI-GF-HGRADE-MINI delivers ±0.5% accuracy but is RoHS non-compliant. All three maintain identical pressure ratings, output characteristics, and package configurations.

Q: Are there any pressure rating differences between the original and substitute parts?

A: Yes. The CPC01GFH has a maximum pressure rating of 5PSI, while all three Amphenol substitutes are rated to 10PSI. This represents an improvement in overpressure protection capability. The operating pressure specification remains 1PSI for all parts.

Q: What is the significance of the port tube diameter change from 0.15" to 0.18"?

A: The port tube diameter increase from 0.15" (3.8mm) to 0.18" (4.57mm) affects the physical tubing interface. Additionally, the port style changes from barbed to barbless. These mechanical differences require verification of tubing compatibility and connection method compatibility in your application before substitution.

Q: Which substitute should I select if RoHS compliance is required?

A: Both 1 PSI-GF-PRIME-MINI and 1 PSI-GF-CGRADE-MINI carry RoHS compliant certification. 1 PSI-GF-HGRADE-MINI is RoHS non-compliant and must not be used in applications requiring RoHS compliance.

Q: Is the fixed 16V supply voltage of the substitutes compatible with my existing circuit?

A: The Amphenol substitutes require exactly 16V supply, whereas the CPC01GFH accepts a range of 3V to 16V. If your circuit supplies variable voltage or voltages below 16V, the substitutes will not function correctly. Verify that your power supply delivers stable 16V before selecting these alternatives.

Q: Do all parts maintain the same operating temperature range?

A: Yes. The CPC01GFH and all three Amphenol substitutes operate across the identical temperature range of -25°C to 85°C with temperature compensation enabled on all parts.
