MPX4200A Equivalent & Substitute Parts

Part Overview

The MPX4200A is an absolute pressure sensor manufactured by NXP Semiconductors, designed for board mount applications with a pressure range of 2.9PSI to 29.01PSI (20kPa to 200kPa). The sensor outputs analog voltage from 0.3V to 4.9V and operates across a temperature range of -40°C to 125°C. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring similar functionality.

Key Parameters

Substitute Part Grouping Explanation

The MPX4250AP qualifies as a substitute for the MPX4200A based on the following critical parameters:

Matching Parameters:

• Pressure Type: Both are absolute pressure sensors
• Output Type: Both provide analog voltage output
• Supply Voltage: Both operate at 4.85V ~ 5.35V
• Operating Temperature: Both function across -40°C ~ 125°C
• Package / Case: Both use 6-SIP Module configuration
• Mounting Type: Both are through hole mounted
• Termination Style: Both use PC Pin termination
• Features: Both include temperature compensation
• Manufacturer: Both manufactured by NXP (NXP USA Inc. is part of NXP Semiconductors)
• Compliance: Both are ROHS3 Compliant and REACH Unaffected

Allowable Differences:

• Operating Pressure Range: MPX4250AP extends to 36.26PSI (250kPa), which encompasses the MPX4200A range of 29.01PSI (200kPa)
• Output Voltage Range: MPX4250AP outputs 0.2V ~ 4.9V versus MPX4200A's 0.3V ~ 4.9V
• Maximum Pressure: MPX4250AP rated to 145.04PSI (1000kPa) versus MPX4200A's 116.03PSI (800kPa)
• Port Configuration: MPX4250AP includes a barbed male port (0.19" / 4.93mm tube) while MPX4200A has no port
• Accuracy: MPX4250AP specifies ±1.5% accuracy

Parameter Comparison

Engineering Selection Recommendations

Both the MPX4200A and MPX4250AP are obsolete products. Selection between these parts depends on application-specific requirements:

Choose MPX4200A if:

• Existing inventory is available and cost is the primary consideration
• The application requires no external port connection
• The system is designed specifically for the 0.3V minimum output threshold

Choose MPX4250AP if:

• Higher pressure range capability (up to 36.26PSI / 250kPa) is beneficial for system margin
• External pneumatic or hydraulic connections are required via the barbed port
• The lower 0.2V minimum output voltage provides better signal resolution
• Higher maximum pressure rating (145.04PSI / 1000kPa) offers additional safety margin

Both parts maintain identical electrical interface characteristics, supply voltage requirements, operating temperature range, and package configuration. Both comply with ROHS3 and REACH requirements. The primary design consideration is the presence of the barbed port on the MPX4250AP and the extended pressure range capability.

Frequently Asked Questions (FAQ)

Q: Can MPX4250AP directly replace MPX4200A in existing designs?

A: Electrical compatibility is confirmed across supply voltage, operating temperature, output type, and package configuration. However, the MPX4250AP includes a barbed male port (0.19" tube) while the MPX4200A has no port. Physical board layout and pneumatic/hydraulic connections must be evaluated for your specific application.

Q: What is the significance of the different output voltage ranges?

A: The MPX4200A outputs 0.3V to 4.9V while the MPX4250AP outputs 0.2V to 4.9V. This difference affects signal conditioning and analog-to-digital conversion scaling. Systems designed for the MPX4200A's 0.3V minimum may require recalibration for the MPX4250AP's 0.2V minimum to maintain measurement accuracy.

Q: Why does the MPX4250AP have a higher maximum pressure rating?

A: The MPX4250AP is rated to 145.04PSI (1000kPa) maximum pressure versus the MPX4200A's 116.03PSI (800kPa). This provides additional overpressure protection margin. The operating pressure range of the MPX4250AP (2.9PSI ~ 36.26PSI) fully encompasses the MPX4200A range (2.9PSI ~ 29.01PSI).

Q: Are both parts suitable for new designs?

A: Both the MPX4200A and MPX4250AP are obsolete products. For new designs, consult NXP's current pressure sensor product line for active alternatives with ongoing manufacturing support and availability.

Q: What are the compliance implications of substitution?

A: Both parts are ROHS3 Compliant and REACH Unaffected. Substitution does not introduce compliance concerns from a regulatory standpoint. However, application-specific certifications or qualifications may require re-evaluation based on the physical and electrical differences noted.
