Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST250PG1SPRF is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Operating pressure range: 250 PSI nominal
• Pressure type: Vented gauge configuration
• Output type: Analog voltage signal
• Accuracy specification: ±1%
• Port connection: Male 1/8" NPT threaded interface
• Maximum pressure rating: 500 PSI minimum
• Features: Amplified output with temperature compensation

Allowable Variation Parameters:

• Output voltage range (within system signal conditioning tolerance)
• Supply voltage range (within available power supply capability)
• Operating temperature range (application-dependent minimum requirements)
• Package configuration (mechanical form factor compatibility)
• Termination style (connector type compatibility)

The substitute part M3041-000006-250PG meets all mandatory matching parameters while maintaining functional equivalence for industrial automation pressure measurement applications.

Parameter Comparison

Engineering Selection Recommendations

The M3041-000006-250PG from TE Connectivity Measurement Specialties (MSP300 series) qualifies as a direct functional substitute for the obsolete ST250PG1SPRF based on the following engineering criteria:

Compliance and Availability:

• The substitute part maintains active product status with current manufacturing availability, eliminating supply chain risk associated with the obsolete main part
• Both parts carry equivalent RoHS compliance certifications (RoHS Compliant and ROHS3 Compliant), satisfying regulatory requirements
• Both parts share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications

Functional Equivalence:

• Identical operating pressure specification (250 PSI) and pressure type (vented gauge)
• Matching accuracy specification (±1%) and output type (analog voltage)
• Identical port interface (Male 1/8" NPT threaded connection)
• Identical maximum pressure rating (500 PSI)
• Identical feature set (amplified output with temperature compensation)

Parameter Compatibility Considerations:

• Output voltage range difference (0.5-4.5 V vs. 1-5 V) is compatible within typical signal conditioning systems
• Supply voltage range difference (7-35 V vs. 10-30 V) is compatible within the overlapping 10-30 V window
• Operating temperature range of the substitute (-20°C to 85°C) is narrower than the main part (-40°C to 100°C); applications requiring operation below -20°C or above 85°C require alternative solutions

Selection of the M3041-000006-250PG is appropriate for industrial automation pressure measurement applications operating within the -20°C to 85°C temperature window with supply voltages in the 10-30 V range.

Frequently Asked Questions (FAQ)

Q: What makes M3041-000006-250PG a valid substitute for ST250PG1SPRF?

A: Both sensors share identical operating pressure (250 PSI), pressure type (vented gauge), output type (analog voltage), accuracy (±1%), port interface (Male 1/8" NPT), maximum pressure rating (500 PSI), and feature set (amplified output with temperature compensation). These parameters define functional equivalence for industrial automation pressure measurement applications.

Q: Are there differences in output voltage between these sensors?

A: Yes. The ST250PG1SPRF outputs 0.5-4.5 V, while the M3041-000006-250PG outputs 1-5 V. Both ranges overlap significantly (1-4.5 V), making them compatible with standard industrial signal conditioning and analog-to-digital conversion systems. System design must account for the different output scaling.

Q: What is the temperature operating range difference?

A: The ST250PG1SPRF operates from -40°C to 100°C, while the M3041-000006-250PG operates from -20°C to 85°C. The substitute part has a narrower range. Applications requiring operation below -20°C or above 85°C cannot use the M3041-000006-250PG and require alternative solutions.

Q: Are the supply voltage requirements compatible?

A: The ST250PG1SPRF requires 7-35 V, while the M3041-000006-250PG requires 10-30 V. The overlapping range is 10-30 V. Systems operating within this window are compatible. Systems requiring operation below 10 V or above 30 V must evaluate alternative parts.

Q: Can I use the M3041-000006-250PG as a direct mechanical replacement?

A: Both sensors use identical Male 1/8" NPT threaded port connections and cylinder metal package configurations, enabling direct mechanical installation. Termination style differs (the substitute includes cable termination), requiring evaluation of connector compatibility with existing wiring harnesses.

Q: What is the inventory status of these parts?

A: The ST250PG1SPRF (obsolete) has 829 pieces in stock. The M3041-000006-250PG (active product) has 866 pieces in stock. The active product status of the substitute ensures long-term availability for future procurement.

Q: Are both parts RoHS compliant?

A: Yes. The ST250PG1SPRF is RoHS Compliant, and the M3041-000006-250PG is ROHS3 Compliant. Both meet current regulatory requirements for restricted substance elimination.
