Substitute Part Grouping Explanation

Substitution of the MPXM12GST1 is determined by the following critical parameters that must remain compatible:

Mechanical Compatibility:

Pressure type (vented gauge)
Port size and style (male 0.12" barbless tube)
Mounting type (surface mount)
Package configuration (5-SMD module, top port)
Termination style (gull wing)

Electrical Compatibility:

Output type (Wheatstone Bridge)
Operating pressure range (1.45 PSI / 10 kPa)
Maximum pressure rating (10.88 PSI / 75 kPa)
Operating temperature range (-40°C ~ 125°C)

The MPXM2010GST1 qualifies as a substitute based on matching all mechanical parameters and core electrical specifications. However, differences exist in supply voltage requirements, output voltage range, and accuracy specifications that must be evaluated for specific application requirements.

Engineering Selection Recommendations

The MPXM2010GST1 is the manufacturer-recommended substitute for the obsolete MPXM12GST1. Both components maintain identical mechanical compatibility and core pressure specifications. The MPXM2010GST1 is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

Supply Voltage Difference: The MPXM12GST1 operates at 3V ~ 6V, while the MPXM2010GST1 requires 10V ~ 16V. Circuit design modifications are necessary to accommodate this voltage requirement change.

Output Voltage Difference: The MPXM12GST1 produces 0 mV ~ 55 mV output at 3V supply, while the MPXM2010GST1 produces 0 mV ~ 25 mV output at 10V supply. Signal conditioning and analog-to-digital conversion parameters must be adjusted accordingly.

Accuracy Improvement: The MPXM2010GST1 provides ±1% accuracy compared to the MPXM12GST1's ±5% accuracy, representing enhanced measurement precision.

Temperature Compensation: The MPXM2010GST1 includes temperature compensation features not specified for the MPXM12GST1.

Both components maintain ROHS3 compliance and identical mechanical interfaces, supporting direct physical substitution with appropriate electrical circuit modifications.

Frequently Asked Questions (FAQ)

Q: Can the MPXM2010GST1 be used as a direct drop-in replacement for the MPXM12GST1?

A: Physical and mechanical compatibility is maintained. However, electrical circuit modifications are required due to different supply voltage requirements (3V ~ 6V versus 10V ~ 16V) and output voltage ranges (0 mV ~ 55 mV versus 0 mV ~ 25 mV). Signal conditioning circuits must be redesigned to accommodate these differences.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by pressure type (vented gauge), operating pressure (1.45 PSI), port configuration (male 0.12" barbless), package type (5-SMD module, top port), and output type (Wheatstone Bridge). All these parameters match between the MPXM12GST1 and MPXM2010GST1.

Q: Why is the MPXM12GST1 listed as obsolete?

A: The MPXM12GST1 has been discontinued by the manufacturer. The MPXM2010GST1 represents the active production alternative within the NXP pressure sensor portfolio.

Q: Are there packaging differences between these components?

A: Both components use identical 5-SMD module packaging with top port configuration and gull wing termination style. Packaging compatibility is maintained.

Q: What compliance certifications apply to both parts?

A: Both the MPXM12GST1 and MPXM2010GST1 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.
