SXP01GSMTP Equivalent & Substitute Parts

Part Overview

The SXP01GSMTP is a surface-mount pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for vented gauge pressure measurement applications. This 8-SMD module sensor operates at 1PSI (6.89kPa) with a Wheatstone Bridge output of 0 mV to 20 mV at 5V supply. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support, maintenance, and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SXP01GSMTP are identified based on the following critical parameters that define functional equivalence:

Primary Matching Criteria:

• Operating pressure range: 1PSI (6.89kPa) nominal
• Pressure measurement type: Vented gauge configuration
• Output signal type: Wheatstone Bridge
• Operating temperature range: -40°C ~ 125°C
• Supply voltage compatibility: 12V operation supported

Secondary Considerations:

• Output sensitivity and full-scale voltage range
• Measurement accuracy specification
• Termination style and mounting configuration
• Product status and availability

The NBPDPNS001PGUNV qualifies as a substitute based on matching the primary operating pressure, pressure type, output signal type, and temperature range. Differences in output range, accuracy, mounting style, and maximum pressure rating represent trade-offs that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SXP01GSMTP is obsolete, while the NBPDPNS001PGUNV is active and in production. For new designs or long-term system support, the active product status of NBPDPNS001PGUNV provides supply chain continuity and manufacturing support.

Compliance and Certification: The NBPDPNS001PGUNV carries RoHS Compliant certification, meeting current environmental and regulatory standards. This status is advantageous for applications subject to RoHS requirements or future regulatory compliance mandates.

Functional Compatibility: Both sensors operate at the same nominal pressure (1PSI / 6.89kPa) with vented gauge configuration and Wheatstone Bridge output. Both support the full -40°C to 125°C operating temperature range and accept 12V supply voltage. The NBPDPNS001PGUNV offers improved accuracy (±0.25% versus ±0.5%) and wider supply voltage range (1.8V to 12V).

Application-Specific Factors: The primary trade-off involves mounting configuration: SXP01GSMTP uses surface-mount SMD termination, while NBPDPNS001PGUNV uses through-hole PC pin termination. PCB layout and assembly process compatibility must be evaluated. The NBPDPNS001PGUNV has a lower maximum pressure rating (10PSI versus 20PSI), which is acceptable for applications operating at or below 1PSI nominal pressure but may limit overpressure margin.

Frequently Asked Questions (FAQ)

Q: Can NBPDPNS001PGUNV directly replace SXP01GSMTP in existing PCB assemblies?

A: Direct PCB replacement is not possible due to different mounting technologies. SXP01GSMTP uses surface-mount SMD termination on an 8-SMD module, while NBPDPNS001PGUNV uses through-hole PC pins in a 4-DIP package. PCB redesign is required to accommodate the different footprint and mounting method.

Q: Are the output signals compatible between these two sensors?

A: Both sensors use Wheatstone Bridge output at the same nominal pressure (1PSI). However, output sensitivity differs: SXP01GSMTP provides 0-20 mV full scale, while NBPDPNS001PGUNV provides 0-32.5 mV full scale. Signal conditioning and analog-to-digital conversion circuits must be recalibrated to accommodate the different output range.

Q: What is the significance of the lower maximum pressure rating on NBPDPNS001PGUNV?

A: NBPDPNS001PGUNV has a maximum pressure rating of 10PSI compared to 20PSI for SXP01GSMTP. For applications operating at the nominal 1PSI pressure, this difference does not affect normal operation. However, if the system experiences pressure transients or overpressure conditions exceeding 10PSI, the NBPDPNS001PGUNV may be damaged. System pressure protection must be evaluated.

Q: Does the improved accuracy of NBPDPNS001PGUNV (±0.25% vs ±0.5%) require system recalibration?

A: The improved accuracy specification of NBPDPNS001PGUNV does not require system recalibration but may improve overall measurement precision. If the original system was designed around ±0.5% accuracy, the substitute part will perform within or better than the original specification. System validation should confirm that improved accuracy does not introduce unexpected behavior in signal processing or control algorithms.

Q: Is the RoHS Compliant status of NBPDPNS001PGUNV important for my application?

A: RoHS compliance is mandatory for products sold in the European Union and increasingly required by global manufacturers and customers. If your application or supply chain requires RoHS compliance, NBPDPNS001PGUNV meets this requirement while SXP01GSMTP status is unspecified. For legacy systems without RoHS requirements, this difference may not be relevant.

Q: Can NBPDPNS001PGUNV operate on lower supply voltages than SXP01GSMTP?

A: Yes. NBPDPNS001PGUNV supports supply voltage from 1.8V to 12V, while SXP01GSMTP operates at 12V. This wider voltage range provides flexibility for battery-powered or low-voltage applications. However, both sensors function correctly at 12V, so this advantage is only relevant if lower supply voltages are required.
