Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5 PSI-G-4V-PRIME-REF is determined by strict alignment of the following critical parameters:

Pressure Specifications: Operating pressure of 5PSI (34.47kPa) and vented gauge pressure type must be maintained. Maximum pressure rating of 15PSI (103.42kPa) establishes the overpressure protection threshold.

Electrical Interface: Output type must remain analog voltage with output range of 0.25V to 4.25V. Supply voltage compatibility must be verified within the operating range of each part.

Mechanical Interface: Port size (Male - 0.19" tube), port style (barbless), and tube diameter specifications must match to ensure pneumatic connection compatibility.

Package and Termination: 4-SIP module package with PC pin through-hole termination is required for board mount applications.

Environmental Performance: Operating temperature range of -40°C to 125°C and temperature compensation feature must be maintained.

The 5 PSI-G-4V-PRIME is identified as a direct substitute based on alignment across all critical parameters within allowable tolerances.

Parameter Comparison

Engineering Selection Recommendations

The 5 PSI-G-4V-PRIME serves as the direct substitute for the obsolete 5 PSI-G-4V-PRIME-REF. Both components share identical pressure specifications, output characteristics, package configuration, and environmental operating parameters.

Product Status Consideration: The 5 PSI-G-4V-PRIME maintains active product status with current manufacturing support, ensuring long-term component availability compared to the obsolete reference part.

Compliance and Certification: The 5 PSI-G-4V-PRIME is RoHS Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement. Both parts carry identical moisture sensitivity classification (MSL 1 - Unlimited) and ECCN/HTSUS designations.

Supply Voltage Difference: The substitute part operates within a narrower supply voltage range (4.5V ~ 5.5V) compared to the main part (5.5V ~ 16V). System designs must verify that power supply specifications fall within the 4.5V to 5.5V window for compatibility.

Accuracy Specification: The substitute part specifies ±0.5% accuracy versus ±0.25% for the main part. Applications requiring the tighter accuracy tolerance of the original part must evaluate whether the ±0.5% specification meets functional requirements.

Mechanical Compatibility: Port tube diameter specifications are nominally equivalent (4.83mm versus 4.8mm), maintaining pneumatic interface compatibility within standard tubing tolerances.

Frequently Asked Questions (FAQ)

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

A: The 5 PSI-G-4V-PRIME is compatible for substitution provided that system power supply operates within the 4.5V to 5.5V range and the ±0.5% accuracy specification satisfies application requirements. The narrower supply voltage range of the substitute part is the primary design consideration.

Q: What are the key differences between these two pressure sensors?

A: The primary differences are product status (obsolete versus active), supply voltage operating range (5.5V ~ 16V versus 4.5V ~ 5.5V), accuracy specification (±0.25% versus ±0.5%), and regulatory compliance documentation (RoHS status explicitly stated for the substitute). All pressure, output, package, and termination specifications are identical.

Q: Are the pneumatic port connections identical between these parts?

A: Both sensors feature male barbless tube ports with nominal dimensions of 0.19" (approximately 4.8mm). The specifications are mechanically compatible for standard tubing connections.

Q: Does the substitute part require any circuit modifications?

A: Circuit modifications are not required for the analog voltage output interface. However, power supply design must be verified to operate within the 4.5V to 5.5V specification of the substitute part. If the original design utilized the extended voltage range (5.5V ~ 16V) of the main part, power supply adjustment may be necessary.

Q: What is the packaging difference between these parts?

A: The main part is specified with packaging designation "-" while the substitute part is packaged in tubes. Both components use identical 4-SIP module package types with PC pin through-hole termination for board mount applications.

Q: Are there any temperature or environmental performance differences?

A: Both sensors operate across the identical temperature range (-40°C to 125°C) and include temperature compensation features. Moisture sensitivity classification (MSL 1 - Unlimited) is identical for both parts.
