SXP100ASMTP Equivalent & Substitute Parts

Part Overview

The SXP100ASMTP is an absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 100 PSI (689.48 kPa) absolute pressure measurement. The sensor outputs a Wheatstone Bridge signal in the range of 0 mV to 150 mV at 5V supply voltage with ±0.5% accuracy. The device is packaged in an 8-SMD module format with SMD termination style and operates across -40°C to 125°C.

The SXP100ASMTP has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SXP100ASMTP is evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Pressure measurement range: 100 PSI (689.48 kPa) absolute
• Output type: Wheatstone Bridge configuration
• Mounting technology: Surface mount (SMD/SMT)
• Operating temperature range: -40°C ~ 125°C minimum
• Supply voltage compatibility: 12V operation capability

Secondary Compatibility Considerations:

• Output signal range and accuracy specifications
• Package form factor and pin configuration
• Maximum pressure rating (overload protection)
• Product status and availability

The NBPLPNN100PAUNV qualifies as a substitute part because it maintains the same operating pressure specification (100 PSI absolute), identical Wheatstone Bridge output type, surface mount termination, matching temperature range, and compatible supply voltage range that includes 12V operation. The substitute part demonstrates improved specifications in accuracy (±0.25% versus ±0.5%), higher maximum pressure rating (240 PSI versus 150 PSI), and active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The NBPLPNN100PAUNV is the qualified substitute for the obsolete SXP100ASMTP based on the following engineering factors:

Product Status and Supply Continuity: The SXP100ASMTP is classified as obsolete, creating supply chain risk. The NBPLPNN100PAUNV maintains active product status with confirmed inventory availability (935 pcs), ensuring long-term sourcing capability.

Functional Equivalence: Both sensors operate at identical 100 PSI absolute pressure specifications with Wheatstone Bridge output configuration. Both support the required -40°C to 125°C operating temperature range and 12V supply voltage operation. Surface mount termination and SMD packaging are consistent across both parts.

Specification Improvements: The substitute part provides enhanced accuracy (±0.25% versus ±0.5%) and higher maximum pressure rating (240 PSI versus 150 PSI), offering improved performance margins without compromising existing application requirements.

Compliance and Environmental Standards: The NBPLPNN100PAUNV carries RoHS compliance certification and EAR99 ECCN classification. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Output Signal Consideration: The substitute part outputs 0 mV to 86 mV versus the original 0 mV to 150 mV. Circuit design review is required to confirm signal conditioning and analog-to-digital conversion compatibility with the reduced output range.

Frequently Asked Questions (FAQ)

Q: Can the NBPLPNN100PAUNV directly replace the SXP100ASMTP without circuit modifications?

A: Both sensors share identical operating pressure (100 PSI absolute), output type (Wheatstone Bridge), supply voltage compatibility (12V), and temperature range (-40°C to 125°C). However, the output signal range differs: SXP100ASMTP outputs 0-150 mV while NBPLPNN100PAUNV outputs 0-86 mV. Signal conditioning circuits and analog-to-digital converter scaling must be reviewed and adjusted accordingly.

Q: What are the key differences in package configuration?

A: The SXP100ASMTP uses an 8-SMD module package, while the NBPLPNN100PAUNV uses a 6-SMD, No Lead, Top Port configuration. Both employ SMD (SMT) Tab termination for surface mount assembly. Physical footprint and PCB layout modifications may be required.

Q: Is the NBPLPNN100PAUNV suitable for applications requiring the original ±0.5% accuracy specification?

A: The substitute part provides ±0.25% accuracy, which exceeds the original ±0.5% requirement. Applications specifying ±0.5% accuracy or lower precision tolerance will operate within acceptable parameters with the substitute part.

Q: What is the significance of the higher maximum pressure rating on the substitute part?

A: The NBPLPNN100PAUNV has a maximum pressure rating of 240 PSI compared to 150 PSI on the original part. This provides additional overload protection margin. Applications operating at or near the original 150 PSI maximum rating benefit from the increased safety margin.

Q: Are there supply voltage differences that affect circuit design?

A: The SXP100ASMTP requires 12V supply voltage. The NBPLPNN100PAUNV operates across 1.8V to 12V range, offering greater supply voltage flexibility. Existing 12V supply designs remain fully compatible.

Q: What is the impact of the different port configurations?

A: The SXP100ASMTP has no port (sealed design). The NBPLPNN100PAUNV features a top port configuration. For sealed pressure measurement applications, the top port design maintains functional equivalence while providing alternative mounting orientation options.
