Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5 PSI-D-4V-PRIME-REF is determined by the following critical parameters:

Mandatory Matching Parameters:

• Pressure Type: Differential
• Operating Pressure: ±5PSI (±34.47kPa)
• Output Type: Analog Voltage
• Output Range: 0.25V ~ 4.25V
• Port Size: Male - 0.19" Tube, Dual
• Port Style: Barbless
• Package Type: 4-SIP Module
• Termination Style: PC Pin
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 125°C
• Maximum Pressure: ±15PSI (±103.42kPa)

Allowable Variation Parameters:

• Accuracy: May vary within engineering tolerance
• Supply Voltage: May differ if compatible with system design
• Product Status: Active status preferred for new sourcing
• RoHS Compliance: May differ based on application requirements

The substitute part 5 PSI-D-4V-PRIME meets all mandatory matching criteria and is therefore classified as a direct equivalent.

Engineering Selection Recommendations

For New Designs and Production: The 5 PSI-D-4V-PRIME is the recommended substitute for the obsolete 5 PSI-D-4V-PRIME-REF. This part maintains functional equivalence across all critical pressure measurement parameters while offering the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• RoHS Compliant designation meets current environmental and regulatory requirements
• Identical pressure measurement specifications (±5PSI differential, 0.25V ~ 4.25V output)
• Matching mechanical interface (male barbless 0.19" dual tube ports)
• Identical thermal operating range (-40°C ~ 125°C)
• Same package configuration (4-SIP module, through-hole mounting)

Design Consideration: The substitute part operates on a narrower supply voltage range (4.5V ~ 5.5V) compared to the original part (5.5V ~ 16V). System designs must verify that the power supply voltage falls within the 4.5V ~ 5.5V window. The substitute part exhibits ±0.5% accuracy versus ±0.25% for the original; applications requiring the higher accuracy specification must evaluate whether this difference impacts system performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5 PSI-D-4V-PRIME directly replace the 5 PSI-D-4V-PRIME-REF in existing assemblies?

A: Yes, the 5 PSI-D-4V-PRIME is a direct mechanical and functional equivalent. Both parts feature identical pressure measurement ranges (±5PSI), output voltage specifications (0.25V ~ 4.25V), port configurations (male barbless 0.19" dual tube), and package types (4-SIP module through-hole). No PCB modifications or mechanical redesign is required.

Q: What is the primary difference between these two parts?

A: The 5 PSI-D-4V-PRIME-REF is obsolete, while the 5 PSI-D-4V-PRIME is an active product. The substitute part is RoHS Compliant, whereas the original is RoHS non-compliant. The substitute operates on a narrower supply voltage range (4.5V ~ 5.5V versus 5.5V ~ 16V) and has a slightly lower accuracy specification (±0.5% versus ±0.25%).

Q: Are there any supply voltage compatibility issues?

A: The substitute part requires a supply voltage between 4.5V and 5.5V. If your system supplies voltage outside this range, the substitute part will not function. Verify your system's power supply voltage specification before implementing this substitution.

Q: Does the accuracy difference affect system performance?

A: The substitute part specifies ±0.5% accuracy compared to ±0.25% for the original. For applications where measurement precision is critical, evaluate whether the doubled accuracy tolerance impacts your system's performance requirements or calibration procedures.

Q: Are the tube port dimensions identical?

A: Both parts feature male barbless tube ports of 0.19" nominal diameter. The original specifies 4.83mm while the substitute specifies 4.8mm. This 0.03mm difference is within standard manufacturing tolerance and does not affect mechanical compatibility.

Q: What is the inventory status for each part?

A: The 5 PSI-D-4V-PRIME-REF has 655 pieces in stock. The 5 PSI-D-4V-PRIME substitute has 694 pieces in stock. Both are available as new original components.
