SX150D Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The SX150D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 100PSI (689.48kPa) differential pressure range and 0 mV ~ 110 mV output. The device operates on a 12V supply and features a Wheatstone Bridge output configuration in a 4-SIP module package.

The SX150D is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SX150D is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 4-SIP Module package with Through Hole mounting to ensure physical and electrical compatibility with existing PCB designs.

Output Configuration: Both parts must feature Wheatstone Bridge output type to maintain signal conditioning compatibility with existing amplification and measurement circuits.

Operating Environment: Temperature range (-40°C ~ 85°C) and supply voltage compatibility must be maintained or exceeded.

Pressure Range Consideration: The substitute part may operate at a different pressure range provided the application does not require the full 100PSI differential range of the original part, or if the substitute's range encompasses the required operating point.

Regulatory Compliance: Both parts must maintain RoHS compliance and equivalent ECCN/HTSUS classifications for regulatory continuity.

The NSCSSNN150PDUNV qualifies as a substitute based on matching package type, output configuration, temperature range, and regulatory status, while offering enhanced accuracy and flexible supply voltage operation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SX150D is obsolete, while the NSCSSNN150PDUNV is active. Selection of the active substitute part ensures long-term component availability and ongoing manufacturer support.

Regulatory Compliance: Both parts maintain RoHS compliance and equivalent ECCN/HTSUS classifications (EAR99 / 9026.20.4000), ensuring regulatory continuity in applications subject to export control or environmental compliance requirements.

Supply Voltage Flexibility: The NSCSSNN150PDUNV operates across a 1.5V ~ 12V supply range, providing broader design flexibility compared to the SX150D's fixed 12V requirement. Existing 12V supply designs remain fully compatible.

Accuracy Enhancement: The NSCSSNN150PDUNV provides ±0.25% accuracy versus the SX150D's ±0.5%, offering improved measurement precision without requiring circuit redesign.

Pressure Range: The NSCSSNN150PDUNV's ±150PSI operating range exceeds the SX150D's 100PSI range. Applications operating within the original 100PSI specification will function within the substitute's operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN150PDUNV directly replace the SX150D in existing designs?

A: Physical and electrical compatibility is established through matching 4-SIP Module package, Through Hole mounting, Wheatstone Bridge output configuration, and identical operating temperature range. The substitute operates on the same 12V supply used by the original part. Signal output scaling differs due to higher pressure range; signal conditioning circuits may require calibration adjustment.

Q: What is the primary difference in output between these two sensors?

A: The SX150D outputs 0 mV ~ 110 mV across its 100PSI range. The NSCSSNN150PDUNV outputs 0 mV ~ 258.5 mV across its ±150PSI range. For equivalent pressure inputs within the 100PSI specification, the NSCSSNN150PDUNV produces proportionally higher output voltage.

Q: Does the NSCSSNN150PDUNV require different supply voltage?

A: No. The NSCSSNN150PDUNV accepts 1.5V ~ 12V supply voltage, making it compatible with existing 12V supply designs. The broader voltage range provides design flexibility for future applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the SX150D and NSCSSNN150PDUNV are RoHS compliant and share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications.

Q: Why is the NSCSSNN150PDUNV classified as active while the SX150D is obsolete?

A: The NSCSSNN150PDUNV is part of Honeywell's active TruStability® NSC series, ensuring ongoing manufacturing, technical support, and component availability. The SX150D has been discontinued and is no longer in active production.

Q: What packaging format is used for the NSCSSNN150PDUNV?

A: The NSCSSNN150PDUNV is supplied in Bulk packaging with PC Pin termination, maintaining the 4-SIP Module form factor required for Through Hole board mount applications.
