Key Parameters

Substitute Part Grouping Explanation

Substitution of the SX7030D is based on the following critical parameters that must align for functional equivalence:

Pressure Specifications: Operating pressure range of 30PSI differential and maximum pressure rating of 60PSI are the primary functional requirements.

Output Characteristics: Wheatstone Bridge output type with voltage-based signal output in the 0-200 mV range at 5V supply.

Physical Form Factor: 4-SIP Module package with through-hole PC pin termination for direct board mount compatibility.

Environmental Compliance: RoHS compliance and operating temperature range of -40°C to 85°C.

Supply Voltage Compatibility: The SX7030D operates at 12V supply. Substitute parts must support this voltage or provide compatible voltage ranges.

The NSCSSNN030PDUNV qualifies as a direct substitute based on matching pressure specifications, output type, package configuration, and environmental operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The NSCSSNN030PDUNV is the direct substitute for the obsolete SX7030D. Both components are manufactured by Honeywell Sensing and Productivity Solutions and share identical pressure specifications, package form factors, and environmental operating ranges.

The NSCSSNN030PDUNV offers improved accuracy (±0.25% versus ±0.5%) and extended supply voltage compatibility (1.5V to 12V versus fixed 12V). The substitute part is currently in active production status with confirmed inventory availability, ensuring long-term component sourcing reliability.

Both parts maintain RoHS compliance and identical moisture sensitivity ratings, supporting equivalent reliability and regulatory requirements for board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN030PDUNV directly replace the SX7030D without circuit modifications?

A: The NSCSSNN030PDUNV is pin-compatible and functionally equivalent for the specified 30PSI differential pressure application. Both components use identical 4-SIP through-hole PC pin termination and Wheatstone Bridge output. The substitute part operates within the same temperature range and maintains RoHS compliance. Circuit validation is required to confirm output signal compatibility, as the NSCSSNN030PDUNV produces 0-207 mV output compared to the SX7030D's 0-110 mV output at 5V supply.

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

A: The SX7030D is an obsolete product from the SX7 series, while the NSCSSNN030PDUNV is an active product from the TruStability® NSC series. The substitute offers improved accuracy specification (±0.25% versus ±0.5%) and broader supply voltage range (1.5V-12V versus fixed 12V). Both maintain identical pressure ratings, package configuration, and operating temperature specifications.

Q: Are there any compatibility concerns with the output voltage difference?

A: The NSCSSNN030PDUNV produces a higher output voltage range (0-207 mV) compared to the SX7030D (0-110 mV). Signal conditioning or amplifier circuits may require adjustment to accommodate the increased output sensitivity. The substitute part's improved accuracy may also affect system calibration requirements.

Q: Is the NSCSSNN030PDUNV available for immediate procurement?

A: The NSCSSNN030PDUNV is classified as an active product with confirmed new original inventory. Availability and lead times should be verified with authorized Honeywell distributors.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both the SX7030D and NSCSSNN030PDUNV are RoHS compliant with identical moisture sensitivity level ratings (MSL 1 - Unlimited). Both carry ECCN EAR99 classification and HTSUS code 9026.20.4000, supporting equivalent regulatory compliance for industrial and commercial applications.
