Substitute Part Grouping Explanation

Substitution eligibility for the MPX5050GP1 is determined by the following critical parameters:

Primary Substitution Criteria:

Pressure Type: Vented Gauge (distinguishes from differential pressure variants)
Operating Pressure: 7.25 PSI (50 kPa)
Output Type: Analog Voltage
Output Range: 0.2 V ~ 4.7 V
Supply Voltage: 4.75 V ~ 5.25 V
Port Size: Male - 0.19" (4.93 mm) Tube
Port Style: Barbed
Package / Case: 6-SIP Module
Mounting Type: Through Hole

Substitute Classification:

MPX5050GP (Parametric Equivalent): Matches all critical parameters including pressure type (vented gauge), operating pressure, output characteristics, and physical form factor. This part is the direct active equivalent with identical functional specifications.

MPX5050DP (Functional Variant): Shares the same series, operating pressure, output range, supply voltage, port size, and package configuration. However, this part operates as a differential pressure sensor rather than vented gauge, making it suitable only for applications where differential pressure measurement is acceptable.

Engineering Selection Recommendations

Primary Selection: MPX5050GP

The MPX5050GP is the recommended substitute for the obsolete MPX5050GP1. Both parts are vented gauge pressure sensors with identical electrical and mechanical specifications. The MPX5050GP maintains active product status with NXP USA Inc., ensuring ongoing availability and supply chain continuity. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The parametric equivalence eliminates design modification requirements.

Secondary Selection: MPX5050DP

The MPX5050DP is suitable only for applications where differential pressure measurement replaces vented gauge measurement. This substitution requires circuit design review and application validation. The dual port configuration (differential measurement) differs fundamentally from the single-port vented gauge design. Selection of this variant is appropriate only when differential pressure sensing aligns with system requirements.

Frequently Asked Questions (FAQ)

Q: Can MPX5050GP directly replace MPX5050GP1 without circuit modification?

A: Yes. The MPX5050GP is a parametric equivalent with identical electrical output characteristics (0.2 V ~ 4.7 V), supply voltage requirements (4.75 V ~ 5.25 V), accuracy (±2.5%), and physical form factor (6-SIP Module, through-hole mounting). No circuit redesign is required.

Q: What is the key difference between MPX5050GP and MPX5050DP?

A: The MPX5050GP measures vented gauge pressure (single port referenced to atmosphere), while the MPX5050DP measures differential pressure (dual ports). Vented gauge sensors require only one pressure input; differential sensors require two independent pressure inputs. Application requirements determine which type is appropriate.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 6-SIP Module package with through-hole termination and identical pin configuration. PCB layout compatibility is maintained across MPX5050GP1, MPX5050GP, and MPX5050DP.

Q: Does the packaging difference (obsolete part vs. active parts) affect electrical performance?

A: No. Packaging format (tray vs. other configurations) affects supply chain and handling procedures but does not alter electrical specifications or performance characteristics.

Q: Are there supply voltage or temperature range limitations when substituting?

A: No. All three parts operate across identical supply voltage (4.75 V ~ 5.25 V) and temperature ranges (-40°C ~ 125°C). Operating conditions remain unchanged.
