Equivalent & Substitute Parts for SX7015D Pressure Sensor

Part Overview

The SX7015D 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 SX7015D is classified as obsolete product status, making identification of equivalent substitute components necessary for ongoing system support and new design implementations where this sensor specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SX7015D is determined by the following critical parameters that must align between the main part and substitute components:

Pressure Measurement Capability: Operating pressure range of ±15PSI (±103.42kPa) differential with maximum pressure rating of ±30PSI (±206.84kPa)

Output Interface: Wheatstone Bridge output configuration with voltage output in the 0 mV to 155 mV range at 5V supply

Physical Form Factor: 4-SIP Module package with through-hole mounting configuration and no port style

Environmental Compliance: RoHS Compliant status and operating temperature range of -40°C to 85°C

Electrical Supply: Compatible supply voltage range supporting the sensor's operational requirements

The NSCSSNN015PDUNV qualifies as a direct substitute based on matching pressure type, differential measurement range, package configuration, mounting method, temperature range, and compliance certifications. The substitute maintains functional equivalence while offering enhanced specifications in accuracy and supply voltage flexibility.

Parameter Comparison

Engineering Selection Recommendations

The NSCSSNN015PDUNV pressure sensor serves as the direct equivalent substitute for the obsolete SX7015D. Both components share identical pressure measurement specifications, package configuration, and environmental operating parameters. The substitute part is manufactured by the same supplier and maintains RoHS compliance certification.

The NSCSSNN015PDUNV offers improved accuracy specification (±0.25% versus ±0.5%) and expanded supply voltage range (1.5V to 12V versus fixed 12V), providing enhanced flexibility for system integration. The substitute's active product status ensures ongoing availability and manufacturing support, addressing the obsolescence constraint of the original SX7015D.

Both sensors employ identical 4-SIP through-hole mounting and Wheatstone Bridge output architecture, supporting direct functional replacement in existing board designs. The output voltage range difference (155 mV maximum versus 110 mV maximum) requires verification of signal conditioning and analog-to-digital conversion circuits to confirm compatibility with existing measurement electronics.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN015PDUNV directly replace the SX7015D in existing circuit boards?

A: The NSCSSNN015PDUNV maintains identical 4-SIP through-hole package dimensions and pinout configuration as the SX7015D. Both sensors provide Wheatstone Bridge output with matching pressure measurement ranges. The substitute part operates within the same temperature range and supply voltage specification. Direct physical and electrical substitution is supported.

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

A: The SX7015D provides 0 mV to 110 mV output at 5V supply, while the NSCSSNN015PDUNV provides 0 mV to 155 mV output at 5V supply. This difference reflects enhanced sensitivity in the substitute part. Signal conditioning circuits and analog-to-digital converters must accommodate the higher maximum output voltage to prevent signal clipping or measurement errors.

Q: Why is the SX7015D classified as obsolete?

A: The SX7015D has reached end-of-life status in Honeywell's product portfolio. The NSCSSNN015PDUNV represents the current active equivalent within the TruStability® NSC series, offering improved specifications and ongoing manufacturing support.

Q: Are both sensors RoHS compliant?

A: Both the SX7015D and NSCSSNN015PDUNV are RoHS Compliant, meeting environmental and regulatory requirements for electronic component manufacturing and deployment.

Q: What is the moisture sensitivity level for these sensors?

A: Both sensors carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage, handling, or deployment.

Q: How do the accuracy specifications compare?

A: The SX7015D provides ±0.5% accuracy, while the NSCSSNN015PDUNV provides ±0.25% accuracy. The substitute part offers improved measurement precision, beneficial for applications requiring tighter pressure measurement tolerances.

Q: Is the supply voltage range compatible?

A: The SX7015D requires 12V supply. The NSCSSNN015PDUNV accepts 1.5V to 12V supply range. Systems designed for 12V operation remain fully compatible. The substitute part provides additional flexibility for lower voltage applications.
