Sensata Technologies P993-1 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The Sensata Technologies P993-1 is an active, board-mount differential pressure sensor designed for applications requiring low-pressure measurement with analog voltage output. This 3-SIP module sensor operates across a temperature range of -10°C to 60°C and delivers output signals between 0.25 V and 4 V. The part is RoHS compliant and currently in active production status with 974 units available in inventory.

Substitute parts are identified to provide design flexibility when the primary part number becomes unavailable or when application requirements necessitate alternative pressure measurement ranges within the same package and electrical interface specifications.

Key Parameters

Substitute Part Grouping Explanation

The P993-1B qualifies as a direct substitute based on the following critical parameters that remain constant across both parts:

• Package configuration: 3-SIP Module
• Mounting method: Through Hole
• Termination interface: PC Pin
• Port connection: Barbed style
• Output signal type: Analog Voltage (0.25 V ~ 4 V)
• Operating temperature range: -10°C ~ 60°C
• Temperature compensation: Enabled
• Compliance certifications: RoHS Compliant, MSL 1
• Manufacturer: Sensata Technologies

The primary difference between P993-1 and P993-1B is the operating pressure range. The P993-1 measures unidirectional differential pressure (0.04 PSI), while the P993-1B measures bidirectional differential pressure (-0.04 ~ 0.04 PSI). Both operate within the same voltage output window and share identical mechanical and electrical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both P993-1 and P993-1B are active production parts from Sensata Technologies with full RoHS compliance and identical MSL ratings. Selection between these parts depends on the application's pressure measurement requirements:

Select P993-1 for applications requiring measurement of positive differential pressure only, with a maximum range of 0.04 PSI.

Select P993-1B for applications requiring bidirectional differential pressure measurement, capable of detecting both positive and negative pressure differentials within the range of -0.04 to +0.04 PSI.

Both parts maintain identical electrical output characteristics (0.25 V ~ 4 V), mechanical interfaces, and thermal operating specifications, ensuring seamless integration into existing PCB designs and signal conditioning circuits.

Frequently Asked Questions (FAQ)

Q: Can P993-1B replace P993-1 in an existing design?

A: Yes, provided the application can accommodate the bidirectional pressure measurement range of P993-1B. The electrical output, package, mounting, and termination are identical. Verify that your pressure source does not exceed the ±0.04 PSI range of the P993-1B.

Q: What is the key difference between these two parts?

A: The operating pressure range differs. P993-1 measures 0.04 PSI unidirectional differential pressure, while P993-1B measures -0.04 to +0.04 PSI bidirectional differential pressure. Both output the same 0.25 V to 4 V signal range.

Q: Are the 3-SIP module packages physically identical?

A: Yes. Both parts use the same 3-SIP Module package with Through Hole mounting and PC Pin termination, ensuring identical PCB footprints and assembly compatibility.

Q: Do both parts require the same signal conditioning circuitry?

A: Yes. Both parts output analog voltage in the 0.25 V to 4 V range with temperature compensation enabled. Signal conditioning requirements are identical.

Q: Are there any compliance differences between P993-1 and P993-1B?

A: No. Both parts are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating and share identical ECCN and HTSUS classifications.

Q: What is the inventory status for these parts?

A: P993-1 has 974 units in stock, and P993-1B has 900 units in stock, both listed as new original inventory.
