SX15D Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SX15D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications. This 4-SIP module sensor measures differential pressure up to 15PSI (103.42kPa) with a Wheatstone Bridge output of 0 mV to 110 mV at 5V supply. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Engineering Selection Recommendations

The NSCSSNN015PDUNV is the designated substitute for the obsolete SX15D. Selection of this replacement component is supported by:

Product Status Consideration: The SX15D is classified as obsolete, whereas the NSCSSNN015PDUNV maintains active product status with ongoing manufacturer support and availability.

Compliance Alignment: Both components maintain identical RoHS compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Functional Compatibility: The 4-SIP module package, through-hole mounting configuration, and Wheatstone Bridge output topology are preserved in the substitute, enabling direct integration into existing PCB designs without layout modifications.

Performance Enhancement: The NSCSSNN015PDUNV provides improved accuracy specification (±0.25% versus ±0.5%) and expanded supply voltage flexibility (1.5V to 12V range), offering design flexibility for future applications while maintaining backward compatibility with 12V supply systems.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN015PDUNV be used as a direct replacement for the SX15D in existing designs?

A: Yes. Both sensors share identical 4-SIP module packaging, through-hole mounting, and Wheatstone Bridge output configuration. The substitute maintains the same operating pressure range (15PSI differential) and temperature operating window (-40°C to 85°C), enabling direct PCB substitution without layout changes.

Q: What are the key differences between the SX15D and NSCSSNN015PDUNV?

A: The primary differences are product status (obsolete versus active), accuracy specification (±0.5% versus ±0.25%), supply voltage range (fixed 12V versus 1.5V to 12V), and output voltage range (0-110 mV versus 0-155 mV). The substitute offers improved performance characteristics while maintaining functional compatibility.

Q: Are there any output signal differences that require circuit modification?

A: The output voltage ranges differ slightly (110 mV maximum for SX15D versus 155 mV for NSCSSNN015PDUNV). Analog signal conditioning circuits may require recalibration to account for the increased output span, though both sensors operate on identical Wheatstone Bridge principles.

Q: Does the NSCSSNN015PDUNV support the same supply voltage as the SX15D?

A: Yes. The NSCSSNN015PDUNV accepts 12V supply voltage, matching the SX15D requirement. Additionally, the substitute supports extended supply voltage operation from 1.5V to 12V, providing design flexibility for lower-power applications.

Q: Are both components RoHS compliant?

A: Yes. Both the SX15D and NSCSSNN015PDUNV are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with lead-free manufacturing processes and environmental compliance requirements.

Q: What is the termination style difference between these sensors?

A: The SX15D uses a button-style supplier package, while the NSCSSNN015PDUNV specifies PC pin termination. Both employ through-hole mounting in 4-SIP module configuration, with the termination style difference reflecting internal lead frame design rather than functional incompatibility.
