Frequently Asked Questions (FAQ)

Q: Can the FXPQ3115BVST1 directly replace the FXPQ3115BV in existing designs?

A: The FXPQ3115BVST1 provides functional substitution for the obsolete FXPQ3115BV based on equivalent pressure measurement range (20 kPa ~ 110 kPa), absolute pressure type, and compatible supply voltage operation (2.5V falls within the 1.95V ~ 3.6V range). Circuit integration requires verification of I2C output compatibility with the original application interface.

Q: What is the primary difference between these two components?

A: The FXPQ3115BV is obsolete, while the FXPQ3115BVST1 is an active product. The substitute implements I2C digital output and operates across an expanded supply voltage range (1.95V ~ 3.6V) compared to the original 2.5V specification. Package configuration differs between TSON and 8-TLGA formats.

Q: Are there packaging considerations for substitution?

A: Yes. The FXPQ3115BV uses TSON packaging, while the FXPQ3115BVST1 uses 8-TLGA (3x5) packaging in Tape & Reel format. PCB layout and footprint modifications are required for physical integration of the substitute component.

Q: Does the FXPQ3115BVST1 maintain the same compliance certifications?

A: The FXPQ3115BVST1 maintains REACH unaffected status consistent with the original component. RoHS compliance status for the substitute is not specified in the provided documentation.

Q: What is the maximum pressure rating for the substitute component?

A: The FXPQ3115BVST1 has a maximum pressure rating of 500 kPa (72.52 PSI), providing overpressure protection beyond the 20 kPa ~ 110 kPa operating range.

Q: Is the supply voltage range expansion significant for circuit design?

A: The FXPQ3115BVST1 operates from 1.95V to 3.6V, compared to the original 2.5V specification. This expanded range provides design flexibility for applications with variable supply voltage conditions while maintaining operation at the original 2.5V level.
