Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MPX2050GSX is determined by alignment across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (MPX2050)
• Output type (Wheatstone Bridge)
• Output range (0 mV ~ 40 mV at 10V supply)
• Supply voltage range (10V ~ 16V)
• Operating pressure rating (7.25 PSI / 50 kPa)
• Maximum pressure rating (29.01 PSI / 200 kPa)
• Operating temperature range (-40°C ~ 125°C)
• Mounting type (Through Hole)
• Package type (4-SIP Module)
• Termination style (PC Pin)

Allowable Variation Parameters:

• Pressure type (Vented Gauge vs. Differential)
• Port size tolerance (0.19" tube diameter with minor dimensional variation)
• Product status (Active substitutes acceptable for obsolete parts)
• Packaging format (Tray acceptable for component sourcing)

The MPX2050DP qualifies as a direct substitute based on matching all mandatory parameters while differing only in pressure type classification and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The MPX2050DP is the qualified substitute for the obsolete MPX2050GSX based on electrical and mechanical parameter alignment. Both components maintain identical output characteristics, supply voltage requirements, and thermal operating specifications. The MPX2050DP carries Active product status, ensuring continued availability and manufacturing support.

The primary functional distinction is pressure type classification: the MPX2050GSX operates as a vented gauge sensor, while the MPX2050DP functions as a differential pressure sensor. This difference reflects the measurement reference point rather than output signal characteristics. Both components deliver equivalent Wheatstone Bridge output within the 0 mV to 40 mV range at 10V supply.

Compliance certifications remain consistent between both parts, with ROHS3 compliance and REACH unaffected status maintained. The substitute part is available in Tray packaging format, suitable for production component sourcing.

Frequently Asked Questions (FAQ)

Q: Can the MPX2050DP directly replace the MPX2050GSX in existing designs?

A: The MPX2050DP matches all critical electrical parameters including output type, output range, supply voltage, and operating temperature specifications. Both components use identical 4-SIP Module packaging with PC Pin termination and Through Hole mounting. The primary consideration is the pressure type difference: vented gauge versus differential measurement. System integration feasibility depends on whether the application requires vented gauge or differential pressure measurement capability.

Q: What is the difference between vented gauge and differential pressure types?

A: Vented gauge pressure sensors reference atmospheric pressure as the zero point, measuring pressure relative to ambient conditions. Differential pressure sensors measure the pressure difference between two independent pressure inputs. Both sensor types in the MPX2050 series deliver identical electrical output characteristics and signal conditioning.

Q: Are the port sizes compatible between these two parts?

A: Both parts feature male barbed tube ports designed for 0.19" tubing. The MPX2050GSX specifies 4.92 mm port diameter, while the MPX2050DP specifies 4.93 mm port diameter with dual port configuration. This minor dimensional variation remains within standard tubing compatibility tolerances.

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

A: The MPX2050DP is currently in Active product status with 3011 pieces available in new original condition. The obsolete MPX2050GSX has 678 pieces in stock. The substitute part's active status ensures ongoing manufacturing availability.

Q: Do both parts meet the same compliance requirements?

A: Both the MPX2050GSX and MPX2050DP maintain ROHS3 compliance and REACH unaffected status. Regulatory compliance specifications are identical between the two components.
