Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 15 PSI-G-4V-PRIME-REF is determined by strict alignment of the following critical parameters:

Pressure Specification: Operating pressure must be 15 PSI (103.42 kPa) vented gauge configuration.

Output Characteristics: Analog voltage output in the 0.25 V ~ 4.25 V range with amplified, temperature-compensated signal conditioning.

Mechanical Interface: Male barbless tube port at 0.19" (4.83 mm) nominal diameter for pneumatic connection.

Electrical Package: 4-SIP module with PC pin termination for through-hole board mounting.

Environmental Performance: Operating temperature range of -40°C ~ 125°C and maximum pressure rating of 45 PSI (310.26 kPa).

The substitute part 15 PSI-G-4V-PRIME meets all these core functional requirements while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The 15 PSI-G-4V-PRIME serves as the direct active equivalent for the obsolete 15 PSI-G-4V-PRIME-REF. Both components are manufactured by Amphenol All Sensors Corporation and share identical pressure specifications, output characteristics, and mechanical interfaces.

Supply Chain Consideration: The substitute part maintains current production status with 1037 units in stock, compared to the obsolete main part with 968 units remaining inventory. For new designs and ongoing production requirements, the 15 PSI-G-4V-PRIME is the appropriate selection.

Compliance Status: The substitute part carries RoHS Compliant certification, providing regulatory advantage for applications subject to environmental compliance requirements. Both parts maintain EAR99 export classification and identical HTSUS coding (9026.20.4000).

Parameter Variance: The substitute exhibits a wider supply voltage tolerance (4.5 V ~ 5.5 V versus 5.5 V ~ 16 V) and slightly reduced accuracy specification (±0.5% versus ±0.25%). These differences require evaluation against specific application requirements. The mechanical port dimensions are nominally equivalent (4.83 mm versus 4.8 mm).

Frequently Asked Questions (FAQ)

Q: Can the 15 PSI-G-4V-PRIME directly replace the 15 PSI-G-4V-PRIME-REF in existing designs?

A: Yes. Both components share identical pressure ratings, output voltage ranges, package configurations, and mechanical interfaces. The substitute is electrically and mechanically compatible for board-level integration.

Q: What are the differences in supply voltage requirements?

A: The main part accepts 5.5 V ~ 16 V input, while the substitute operates on 4.5 V ~ 5.5 V. Applications using the wider voltage range of the obsolete part require circuit redesign to accommodate the narrower specification of the substitute.

Q: How do the accuracy specifications differ?

A: The main part specifies ±0.25% accuracy, while the substitute specifies ±0.5%. Applications requiring the tighter tolerance of the original part must evaluate whether the substitute's accuracy meets system-level performance requirements.

Q: Are the tube port dimensions identical?

A: The dimensions are nominally equivalent. The main part specifies 0.19" (4.83 mm), and the substitute specifies 0.19" (4.8 mm). Both use barbless male tube connections and are compatible with standard pneumatic tubing interfaces.

Q: What is the significance of RoHS Compliance on the substitute part?

A: The substitute carries RoHS Compliant certification, indicating compliance with Restriction of Hazardous Substances regulations. This provides regulatory advantage for applications subject to environmental compliance requirements in regulated markets.

Q: Are both parts available in the same packaging format?

A: Yes. Both components are supplied in 4-SIP module packages with PC pin termination for through-hole mounting. The substitute is available in tube packaging with 1037 units in current stock.
