ST150PG2BPCF Equivalent & Substitute Parts

Part Overview

The ST150PG2BPCF is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for industrial automation applications. This sensor provides analog voltage output in the 0.5 V to 4.5 V range with ±1% accuracy across a 0–150 PSI operating pressure range. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for continued system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the ST150PG2BPCF is determined by the following critical parameters:

Mandatory Matching Parameters:

Operating pressure range: 0–150 PSI minimum
Pressure type: Vented gauge configuration
Output type: Analog voltage signal
Port size and style: Male 1/4" NPT threaded connection
Package form factor: Cylinder configuration

Compatible Variation Parameters:

Output voltage range: May differ from 0.5–4.5 V if system signal conditioning accommodates the alternative range
Supply voltage: May differ if power supply capability exists
Accuracy: May be superior (tighter tolerance) to ±1%
Operating temperature range: May be narrower than –40°C to 100°C
Maximum pressure rating: May exceed 450 PSI

The IPSU-GP150-6 manufactured by Sensata-Cynergy3 satisfies all mandatory matching parameters and qualifies as a functional equivalent.

Engineering Selection Recommendations

ST150PG2BPCF (Original Part): Retain for applications where the specific output voltage range (0.5–4.5 V), 5 V single supply voltage, extended low-temperature operation (–40°C), and 450 PSI overpressure rating are system requirements. Product status is obsolete; procurement availability is limited.

IPSU-GP150-6 (Substitute Part): Select for new designs or system upgrades where the following conditions are met:

Signal conditioning or analog-to-digital conversion can accommodate the 0–5 V output range
Power supply infrastructure supports 9–32 V operation
Operating temperature range of –20°C to 80°C satisfies application requirements
Maximum pressure exposure does not exceed 300 PSI
Current RoHS3 compliance is required for regulatory or procurement standards

Both parts are classified as obsolete. The IPSU-GP150-6 offers superior accuracy (±0.25% versus ±1%) and current regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the IPSU-GP150-6 directly replace the ST150PG2BPCF without circuit modifications?

A: Direct replacement is not possible without signal conditioning modifications. The output voltage ranges differ (0–5 V versus 0.5–4.5 V), and the supply voltage requirements differ (9–32 V versus 5 V). System electronics must be evaluated and adjusted accordingly.

Q: What is the impact of the different output voltage ranges?

A: The ST150PG2BPCF outputs 0.5–4.5 V across 0–150 PSI, while the IPSU-GP150-6 outputs 0–5 V across the same pressure range. Analog-to-digital converters, signal conditioning circuits, or calibration tables must be reconfigured to correctly interpret pressure values from the substitute part.

Q: Is the narrower operating temperature range of the IPSU-GP150-6 a limitation?

A: The IPSU-GP150-6 operates from –20°C to 80°C, compared to the ST150PG2BPCF range of –40°C to 100°C. If the application requires operation below –20°C or above 80°C, the IPSU-GP150-6 is not suitable. Verify actual system temperature exposure before selection.

Q: Why does the IPSU-GP150-6 have a lower maximum pressure rating?

A: The IPSU-GP150-6 maximum pressure is 300 PSI versus 450 PSI for the ST150PG2BPCF. This difference reflects different sensor design specifications. If system overpressure conditions may exceed 300 PSI, the IPSU-GP150-6 does not provide equivalent protection.

Q: Are both parts suitable for industrial automation applications?

A: Both parts are specified for industrial automation. However, both are classified as obsolete products. For new system designs, consult current product lines from Honeywell and Sensata-Cynergy3 to identify non-obsolete alternatives with extended availability and support.

Q: What is the significance of RoHS3 compliance on the IPSU-GP150-6?

A: RoHS3 compliance indicates the IPSU-GP150-6 meets current European Union Restriction of Hazardous Substances regulations. The ST150PG2BPCF carries RoHS compliance status, which may reflect an earlier regulatory framework. For procurement requiring current compliance certification, the IPSU-GP150-6 is the appropriate selection.

Q: Can the IPSU-GP150-6 be used in applications requiring the full –40°C to 100°C temperature range?

A: No. The IPSU-GP150-6 is rated only to –20°C to 80°C. Applications requiring the full extended temperature range of the ST150PG2BPCF require alternative components or the original part if procurement is possible.
