Substitute Part Grouping Explanation

Substitution of the ST015PG2BPCF is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure of 15 PSI, vented gauge type, and maximum pressure rating of 45 PSI must be maintained.

Electrical Interface: Output type must be analog voltage with 0.5V to 4.5V range. Supply voltage must be compatible with 5V systems.

Mechanical Interface: Port size must be Male 1/4" NPT threaded connection to ensure direct installation compatibility.

Performance Characteristics: Amplified output and temperature compensation features must be present. Operating temperature range must cover -40°C to 100°C minimum.

Compliance Requirements: RoHS compliance status must be maintained for regulatory adherence.

The substitute part US331-000005-015PG from TE Connectivity Measurement Specialties meets all these critical parameters and is classified as an active product, providing a viable replacement for the obsolete ST015PG2BPCF.

Frequently Asked Questions (FAQ)

Q: Can the US331-000005-015PG directly replace the ST015PG2BPCF without system modifications?

A: Yes. Both sensors share identical pressure specifications (0-15 PSI), output range (0.5V-4.5V), and mechanical interface (Male 1/4" NPT). Direct installation is possible without circuit or mechanical changes.

Q: What is the significance of the improved accuracy specification in the substitute part?

A: The US331-000005-015PG provides ±0.25% accuracy versus the original ±1%. This represents a four-fold improvement in measurement precision. Systems requiring higher accuracy benefit from this enhancement, while applications tolerating ±1% accuracy remain fully compatible.

Q: Does the extended temperature range of the US331-000005-015PG affect compatibility?

A: No. The substitute part's -40°C to 105°C range encompasses the original -40°C to 100°C specification. Extended range provides additional operational margin without affecting existing system performance.

Q: Are there termination differences between these parts?

A: The ST015PG2BPCF termination style is not specified in available documentation. The US331-000005-015PG uses cable termination. Verify termination compatibility with your specific application requirements before selection.

Q: What is the significance of the supply voltage range difference?

A: The ST015PG2BPCF requires 5V nominal supply. The US331-000005-015PG accepts 4.75V to 5.25V, providing ±2.5% tolerance. This wider tolerance improves compatibility with real-world power supplies that may not deliver exactly 5V.

Q: Are both parts RoHS compliant?

A: Yes. The ST015PG2BPCF is RoHS Compliant. The US331-000005-015PG is ROHS3 Compliant, representing the current RoHS directive standard. Both meet environmental and regulatory requirements for industrial applications.

Q: What packaging differences exist between these sensors?

A: The ST015PG2BPCF is specified as Cylinder, Metal. The US331-000005-015PG is specified as Cylinder. Both use cylindrical metal housings suitable for industrial pressure measurement applications.
