XPX150D Equivalent & Substitute Parts

Part Overview

The XPX150D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 150PSI (1034.21kPa) differential pressure measurement. The sensor outputs a Wheatstone Bridge signal in the range of 0 mV to 262.5 mV at 5V supply, with ±1% accuracy across an operating temperature range of -25°C to 85°C.

The XPX150D carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain system functionality, ensure continued availability for production and repair applications, and access improved performance characteristics available in active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPX150D is determined by strict alignment of the following critical parameters:

Pressure Specifications: Operating pressure of 150PSI differential and maximum pressure rating of 250PSI must be maintained. The NSCSMNN150PDUNV operates at ±150PSI differential with ±250PSI maximum pressure, satisfying this requirement.

Output Characteristics: Both the main part and substitute must employ Wheatstone Bridge output topology. Output voltage range compatibility is evaluated within acceptable system tolerance margins.

Electrical Interface: Supply voltage range, termination style (PC Pin), and package configuration (4-SIP Module) must remain consistent to ensure direct board-level compatibility without circuit redesign.

Environmental Compliance: RoHS compliance status must be maintained. Both parts meet RoHS requirements.

Physical Form Factor: Through-hole mounting and 4-SIP module packaging ensure mechanical interchangeability without PCB layout modification.

The NSCSMNN150PDUNV qualifies as a direct substitute based on these parameters while offering improved accuracy (±0.25% versus ±1%) and extended lower temperature operating range (-40°C versus -25°C).

Parameter Comparison

Engineering Selection Recommendations

The NSCSMNN150PDUNV is the qualified substitute for the obsolete XPX150D. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain identical RoHS compliance status and moisture sensitivity classification.

The NSCSMNN150PDUNV carries active product status, ensuring ongoing availability and supply chain continuity. This part is part of the TruStability® NSC series, representing current-generation technology from the manufacturer.

From a compliance perspective, both parts carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, maintaining regulatory consistency in procurement and export documentation.

The substitute part provides enhanced performance characteristics including improved accuracy specification (±0.25% versus ±1%) and extended lower temperature operating capability (-40°C versus -25°C). The output voltage range difference (258.5 mV versus 262.5 mV) represents a 1.5% variation within typical system calibration tolerances for Wheatstone Bridge sensor applications.

Frequently Asked Questions (FAQ)

Q: Can the NSCSMNN150PDUNV be used as a direct replacement for the XPX150D without circuit modification?

A: Yes. Both parts employ identical 4-SIP module packaging, PC pin termination, through-hole mounting, and Wheatstone Bridge output topology. No PCB layout changes are required for physical installation.

Q: What is the significance of the output voltage range difference between the two parts?

A: The XPX150D outputs 0 mV to 262.5 mV while the NSCSMNN150PDUNV outputs 0 mV to 258.5 mV. This 1.5% difference is typical in Wheatstone Bridge sensor design and falls within standard system calibration ranges. Existing signal conditioning circuits will accommodate this variation.

Q: Does the NSCSMNN150PDUNV support the same supply voltage range as the XPX150D?

A: The NSCSMNN150PDUNV supports 1.5V to 12V supply, which encompasses the XPX150D range of 3V to 12V. The substitute part offers extended lower voltage capability.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts carry identical RoHS compliance status, ECCN classification (EAR99), and HTSUS code (9026.20.4000). Regulatory documentation remains consistent.

Q: What is the practical impact of the improved accuracy specification in the NSCSMNN150PDUNV?

A: The NSCSMNN150PDUNV provides ±0.25% accuracy compared to the XPX150D's ±1% accuracy. This represents a four-fold improvement in measurement precision, beneficial for applications requiring tighter pressure measurement tolerances.

Q: Is the extended temperature range of the NSCSMNN150PDUNV (-40°C to 85°C) relevant for typical applications?

A: The extended lower temperature capability (-40°C versus -25°C) provides operational margin for applications in cold environments or equipment subjected to thermal cycling. This enhancement does not negatively impact existing system designs.

Q: What is the inventory status of these parts?

A: The XPX150D is obsolete with 715 pieces in stock. The NSCSMNN150PDUNV is an active product with 982 pieces in stock, providing superior long-term availability assurance.
