SXP15ASMTP Equivalent & Substitute Parts

Part Overview

The SXP15ASMTP is a surface-mount pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for absolute pressure measurement applications with a rated operating pressure of 15 PSI (103.42 kPa). The sensor outputs a Wheatstone Bridge signal in the range of 0 mV to 112.5 mV at 5V supply voltage and operates across a temperature range of -40°C to 125°C.

The SXP15ASMTP is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to support ongoing maintenance, repair, and redesign requirements for systems currently utilizing this component. Substitute parts must maintain compatibility with the specified pressure range, output characteristics, and surface-mount packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SXP15ASMTP must satisfy the following criteria based on provided specifications:

Mandatory Compatibility Parameters:

• Pressure Type: Absolute
• Operating Pressure: 15 PSI (103.42 kPa)
• Output Type: Wheatstone Bridge
• Mounting Type: Surface Mount (SMD/SMT)
• Operating Temperature Range: -40°C to 125°C
• Maximum Pressure: 30 PSI (206.84 kPa)
• RoHS Compliance: Required

Allowable Variations:

• Voltage Supply: The substitute may operate across a different supply voltage range provided it includes 12V operation or can be configured for 12V operation
• Output Signal Range: The substitute may have a different output voltage range (0 mV to 75 mV versus 0 mV to 112.5 mV) as long as the sensor maintains the specified pressure measurement range
• Accuracy: The substitute may have equal or better accuracy than ±0.5%
• Package Configuration: The substitute may differ in SMD package style and pin count provided it maintains surface-mount compatibility

The NBPLPNN015PAUNV meets these substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The NBPLPNN015PAUNV is a qualified substitute for the SXP15ASMTP based on the following engineering criteria:

Pressure Measurement Compatibility: Both sensors measure absolute pressure at 15 PSI (103.42 kPa) with identical maximum pressure ratings of 30 PSI (206.84 kPa). The Wheatstone Bridge output topology is identical, ensuring signal conditioning compatibility.

Temperature and Environmental Compliance: Both parts operate across the identical temperature range of -40°C to 125°C and maintain RoHS compliance with MSL 1 (Unlimited) moisture sensitivity rating, supporting equivalent reliability in environmental conditions.

Supply Voltage Consideration: The NBPLPNN015PAUNV operates across a wider supply voltage range (1.8V to 12V) compared to the fixed 12V specification of the SXP15ASMTP. This provides operational flexibility while maintaining full compatibility at the 12V supply level.

Accuracy Enhancement: The NBPLPNN015PAUNV provides improved accuracy of ±0.25% compared to the SXP15ASMTP's ±0.5%, representing a measurable performance advantage.

Product Status: The NBPLPNN015PAUNV maintains active product status, ensuring ongoing availability and manufacturing support, whereas the SXP15ASMTP is obsolete.

Package and Integration: The NBPLPNN015PAUNV uses a 6-SMD, no-lead, top-port configuration compared to the 8-SMD module of the main part. PCB layout and signal routing must be evaluated for compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the NBPLPNN015PAUNV directly replace the SXP15ASMTP in existing designs?

A: The NBPLPNN015PAUNV is functionally equivalent for pressure measurement at 15 PSI absolute with identical Wheatstone Bridge output and temperature range. However, the package configuration differs (6-SMD no-lead versus 8-SMD module), requiring PCB layout verification and potential redesign of the sensor mounting footprint.

Q: What is the significance of the different output signal ranges (112.5 mV versus 75 mV)?

A: Both sensors operate at 5V supply and measure the same 15 PSI pressure range. The different output ranges reflect different sensor sensitivities. Signal conditioning and analog-to-digital conversion circuits must be calibrated for the specific output range of the selected part. The NBPLPNN015PAUNV's 75 mV range provides proportionally equivalent pressure resolution.

Q: Why does the NBPLPNN015PAUNV have a wider supply voltage range?

A: The NBPLPNN015PAUNV is designed to operate across 1.8V to 12V, providing design flexibility for systems with variable supply voltages. The SXP15ASMTP requires a fixed 12V supply. Both parts function identically at 12V operation.

Q: Is the improved accuracy of the NBPLPNN015PAUNV (±0.25% versus ±0.5%) significant for my application?

A: Accuracy improvement depends on application requirements. The NBPLPNN015PAUNV provides tighter tolerance specifications, which may be beneficial for precision measurement applications. Existing system designs based on ±0.5% accuracy will function with the improved accuracy of the substitute part.

Q: What are the port configuration differences between these sensors?

A: The SXP15ASMTP features a male barbless port for 0.08" (2.05mm) tube connection. The NBPLPNN015PAUNV is specified as "no port" with top-port configuration, indicating an integrated pressure inlet design. System integration must account for these different pressure coupling methods.

Q: Are both parts suitable for the same environmental and temperature conditions?

A: Yes. Both sensors operate across -40°C to 125°C, maintain RoHS compliance, and carry MSL 1 (Unlimited) ratings, ensuring equivalent environmental performance and reliability characteristics.
