Substitute Part Grouping Explanation

Substitution of the ST250PG2BPCF is determined by strict equivalence across the following critical parameters:

Pressure Measurement Specifications: Operating pressure range of 0-250 PSI and maximum pressure rating of 500 PSI must be maintained.

Electrical Interface: Output type must be analog voltage with signal range of 0.5V to 4.5V. Supply voltage tolerance must accommodate the 5V requirement.

Accuracy and Compensation: Accuracy specification of ±1% and temperature compensation are mandatory for functional equivalence.

Mechanical Interface: Port connection must be Male 1/4" (6.35mm) NPT threaded to ensure direct installation compatibility.

Environmental Compliance: RoHS compliance status must match the original specification.

The M5131-000005-250PG from TE Connectivity Measurement Specialties meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

The M5131-000005-250PG qualifies as a direct functional substitute for the obsolete ST250PG2BPCF based on the following engineering criteria:

Product Status Alignment: The substitute part carries active product status, ensuring ongoing manufacturer support, availability, and continued compliance updates. The original ST250PG2BPCF is classified as obsolete, creating supply chain risk for maintenance and new installations.

Electrical Compatibility: The substitute operates within a 4.75V to 5.25V supply voltage range, which encompasses the 5V requirement of the original design. Output signal characteristics remain identical at 0.5V to 4.5V, ensuring direct signal compatibility with existing control systems and data acquisition interfaces.

Mechanical and Functional Equivalence: Identical pressure measurement range (0-250 PSI), port configuration (Male 1/4" NPT), and accuracy specification (±1%) enable direct installation without mechanical or electrical interface modifications.

Environmental Performance: The substitute extends the operating temperature range to -40°C to 125°C, providing enhanced thermal performance compared to the original -40°C to 100°C specification. Both devices maintain RoHS compliance and equivalent moisture sensitivity ratings.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the M5131-000005-250PG directly replace the ST250PG2BPCF without circuit modifications?

A: Yes. Both sensors deliver identical 0.5V to 4.5V output signals with ±1% accuracy across the 0-250 PSI measurement range. The substitute's 4.75V to 5.25V supply voltage range is compatible with 5V power supplies. No signal conditioning or interface changes are required.

Q: What is the difference in termination between these two sensors?

A: The ST250PG2BPCF termination style is not specified in the available data. The M5131-000005-250PG includes a 2-foot cable termination. Integration requirements should be evaluated based on the specific installation environment and control system interface specifications.

Q: Are there temperature performance differences between these sensors?

A: The M5131-000005-250PG operates across -40°C to 125°C, extending 25°C above the ST250PG2BPCF's -40°C to 100°C range. Both sensors include temperature compensation. The extended range of the substitute provides additional operational margin in high-temperature industrial environments.

Q: Do both sensors use the same port connection type?

A: Yes. Both sensors feature Male 1/4" (6.35mm) NPT threaded ports, enabling direct mechanical installation compatibility without adapter requirements.

Q: What is the inventory status for the substitute part?

A: The M5131-000005-250PG is available with 994 pieces in new original stock, compared to 888 pieces for the obsolete ST250PG2BPCF. The substitute's active product status ensures continued availability for future orders.

Q: Are both sensors RoHS compliant?

A: Yes. Both the ST250PG2BPCF and M5131-000005-250PG carry RoHS compliance certification with identical moisture sensitivity level (MSL) ratings of 1 (Unlimited).
