FXPQ3115BVT1 Equivalent & Substitute Parts

Part Overview

The FXPQ3115BVT1 is an absolute pressure sensor manufactured by NXP Semiconductors, designed for board mount applications with a measurement range of 2.9PSI to 15.95PSI (20kPa to 110kPa). The device features digital I2C output, operates at 2.5V supply voltage, and is housed in an 8-TLGA surface mount package. This part is classified as obsolete, making equivalent substitute components necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FXPQ3115BVT1 is based on the following critical parameters:

Pressure Measurement Capability: The substitute parts must support absolute pressure measurement within or overlapping the operating range of 2.9PSI to 15.95PSI (20kPa to 110kPa).

Digital Communication Interface: The FXPQ3115BVT1 uses I2C output. Substitute parts must support I2C protocol to maintain firmware and circuit compatibility.

Supply Voltage Compatibility: The original part operates at 2.5V. Substitute parts with wider supply voltage ranges (1.8V to 3.6V) are compatible when the system can accommodate the extended range.

Surface Mount Packaging: Both substitute parts use 8-SMD surface mount packages, maintaining compatibility with existing PCB layouts designed for surface mount assembly.

Operating Temperature Range: The substitute parts maintain the same -40°C to 85°C operating temperature specification.

Compliance Standards: Both substitute parts meet ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original component.

The two substitute parts identified (MS560702BA03-50 and MS561101BA03-50) are functionally equivalent TE Connectivity Measurement Specialties sensors that satisfy these substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Both MS560702BA03-50 and MS561101BA03-50 are active production components from TE Connectivity Measurement Specialties, providing long-term availability compared to the obsolete FXPQ3115BVT1. Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

The substitute parts offer extended supply voltage ranges (1.8V to 3.6V) compared to the fixed 2.5V of the original part, providing design flexibility for systems with variable power supplies. Both substitutes support I2C communication protocol, maintaining compatibility with existing firmware implementations.

The operating pressure range of the substitute parts (0.15PSI to 17.4PSI) encompasses the original part's range (2.9PSI to 15.95PSI), ensuring measurement capability across the required operating window. The higher maximum pressure rating (87.02PSI versus 72.52PSI) provides additional safety margin.

Package differences exist between the original 8-TLGA and substitute 8-SMD configurations. PCB layout modifications may be required to accommodate the different package footprints, though both maintain surface mount assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can MS560702BA03-50 and MS561101BA03-50 be used interchangeably with FXPQ3115BVT1?

A: Both substitute parts support the same absolute pressure measurement type, I2C digital output, and operating temperature range as the original component. The primary consideration is PCB layout compatibility with the 8-SMD package versus the original 8-TLGA package. Firmware compatibility depends on I2C protocol implementation, which both substitutes support.

Q: What is the difference between MS560702BA03-50 and MS561101BA03-50?

A: Both parts are functionally equivalent pressure sensors from TE Connectivity with identical electrical specifications: 0.15PSI to 17.4PSI operating range, 24-bit output resolution, I2C/SPI interface, and 1.8V to 3.6V supply voltage. The primary difference is the base product number (MS5607 versus MS5611), which may reflect different internal calibration or manufacturing batches. Both are active production components with equivalent availability.

Q: Are the substitute parts compatible with 2.5V supply voltage systems?

A: Yes. Both MS560702BA03-50 and MS561101BA03-50 operate across 1.8V to 3.6V supply voltage range, which includes the original 2.5V specification. Systems designed for 2.5V operation can use these substitutes without power supply modifications.

Q: What packaging considerations apply when switching from FXPQ3115BVT1 to the substitute parts?

A: The original FXPQ3115BVT1 uses 8-TLGA packaging, while both substitute parts use 8-SMD packaging. PCB footprint redesign is required to accommodate the different package geometry. Both packages are surface mount compatible, but land pattern, solder pad dimensions, and component placement coordinates will differ.

Q: Do the substitute parts maintain the same regulatory compliance?

A: Yes. Both MS560702BA03-50 and MS561101BA03-50 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original FXPQ3115BVT1. Moisture sensitivity level (MSL 1 - Unlimited) is also equivalent across all three parts.

Q: What is the advantage of the higher maximum pressure rating in the substitute parts?

A: The substitute parts have a maximum pressure rating of 87.02PSI (600kPa) compared to 72.52PSI (500kPa) for the original part. This provides additional overpressure protection and safety margin in applications where transient pressure spikes may occur above the normal operating range.
