CPC01GH Pressure Sensor Equivalent & Substitute Parts

Part Overview

The CPC01GH is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 1 PSI (6.89 kPa) operating pressure range and Wheatstone Bridge output. The sensor delivers 0 mV to 18 mV output at 12V supply with ±2% accuracy and operates across -25°C to 85°C. The CPC01GH is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support, maintenance, and new design implementations where this sensor specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CPC01GH are identified based on strict parameter matching across the following critical specifications:

Core Compatibility Parameters:

• Pressure Type: Vented Gauge
• Operating Pressure: 1 PSI (6.89 kPa)
• Output Type: Wheatstone Bridge
• Output Range: 0 mV ~ 18 mV (12V)
• Operating Temperature: -25°C ~ 85°C
• Mounting Type: Through Hole
• Package / Case: 4-SIP Module
• Features: Temperature Compensated

All three substitute parts (1 PSI-G-HGRADE-MINI, 1 PSI-G-CGRADE-MINI, 1 PSI-G-PRIME-MINI) manufactured by Amphenol All Sensors Corporation meet these core parameters. Differences exist in accuracy specifications, maximum pressure ratings, supply voltage specifications, RoHS compliance status, and product status (all substitutes are active products). These variations allow selection based on application-specific accuracy requirements and regulatory compliance needs.

Parameter Comparison

Engineering Selection Recommendations

For RoHS-Compliant Applications: Select either 1 PSI-G-CGRADE-MINI or 1 PSI-G-PRIME-MINI. Both parts maintain RoHS compliance status matching the original CPC01GH specification. The 1 PSI-G-CGRADE-MINI provides ±1% accuracy with active product status and full inventory availability. The 1 PSI-G-PRIME-MINI offers superior ±0.25% accuracy for applications requiring tighter tolerance control, also with active product status.

For Non-RoHS-Restricted Applications: The 1 PSI-G-HGRADE-MINI is available as an alternative, offering ±0.5% accuracy with active product status. This part does not carry RoHS compliance certification.

Supply Voltage Consideration: All substitute parts operate at fixed 16V supply, compared to the CPC01GH's 3V to 16V range. Verify that system designs accommodate this fixed voltage specification.

Maximum Pressure Rating: All substitute parts support 10 PSI (68.95 kPa) maximum pressure, providing higher overpressure protection compared to the CPC01GH's 5 PSI (34.47 kPa) rating.

Product Status: All three substitute parts carry active product status, ensuring ongoing availability and manufacturer support, contrasting with the obsolete CPC01GH.

Frequently Asked Questions (FAQ)

Q: Can the 1 PSI-G-CGRADE-MINI directly replace the CPC01GH in existing designs?

A: The 1 PSI-G-CGRADE-MINI matches all core functional parameters: vented gauge pressure type, 1 PSI operating pressure, Wheatstone Bridge output, 0 mV to 18 mV output range, -25°C to 85°C operating temperature, through-hole mounting, and 4-SIP module package. The fixed 16V supply voltage specification differs from the CPC01GH's 3V to 16V range; verify system power supply compatibility. RoHS compliance status matches the original part.

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

A: The three parts differ in accuracy specification and RoHS compliance. The 1 PSI-G-PRIME-MINI provides ±0.25% accuracy (highest precision), the 1 PSI-G-HGRADE-MINI provides ±0.5% accuracy, and the 1 PSI-G-CGRADE-MINI provides ±1% accuracy (closest to the CPC01GH's ±2%). The 1 PSI-G-HGRADE-MINI is RoHS non-compliant, while the other two are RoHS compliant. All three are active products with full inventory availability.

Q: Are there any mechanical compatibility concerns with the 4-SIP module package?

A: All substitute parts use the same 4-SIP module package and through-hole mounting type as the CPC01GH. No mechanical redesign is required for PCB layout or mounting hardware. Verify termination style compatibility; substitute parts feature PC Pin termination.

Q: Why do the substitute parts have a higher maximum pressure rating?

A: The substitute parts support 10 PSI (68.95 kPa) maximum pressure compared to the CPC01GH's 5 PSI (34.47 kPa). This provides additional overpressure protection margin and does not affect normal operation at the 1 PSI operating pressure specification.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring RoHS compliance, select either 1 PSI-G-CGRADE-MINI for standard accuracy applications or 1 PSI-G-PRIME-MINI for high-precision applications. Both parts are active products with established supply chains. Verify that the fixed 16V supply voltage specification aligns with system power architecture.
