Mandatory Matching Parameters:

• Operating Pressure: 1PSI (6.89kPa)
• Pressure Type: Vented Gauge
• Output Type: Analog Voltage
• Output Range: 0.25V ~ 4.25V
• Port Size: Male - 0.19" (4.8mm) Tube
• Port Style: Barbless
• Package / Case: 4-SIP Module
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Maximum Pressure: 5PSI (34.47kPa)
• Features: Amplified Output, Temperature Compensated

The substitute part 1 PSI-G-4V-PRIME meets all mandatory matching parameters and is therefore classified as a direct equivalent for the obsolete 1 PSI-G-4V-PRIME-REF.

Parameter Comparison

Engineering Selection Recommendations

The 1 PSI-G-4V-PRIME is the direct substitute for the obsolete 1 PSI-G-4V-PRIME-REF. Both components are manufactured by Amphenol All Sensors Corporation and share identical functional specifications for pressure sensing, output characteristics, and mechanical interfaces.

The substitute part 1 PSI-G-4V-PRIME is currently in active production status with confirmed inventory availability (1111 pcs), ensuring reliable sourcing for replacement or new applications. The substitute carries RoHS Compliance certification, meeting current environmental and regulatory standards.

Differences between the main part and substitute are limited to supply voltage range and accuracy specification. The substitute operates within a narrower supply voltage window (4.5V ~ 5.5V versus 5.5V ~ 16V) and specifies ±0.5% accuracy compared to ±0.25% for the main part. These differences must be evaluated against specific system requirements prior to implementation.
