Key Parameters

Substitute Part Grouping Explanation

Substitution of the FXPS7250DI4T1 is determined by strict equivalence across the following critical parameters:

• Pressure Type & Range: Absolute pressure measurement capability within 2.9 PSI to 36.26 PSI (20 kPa to 250 kPa)
• Output Interface: I2C digital communication protocol
• Output Resolution: 32-bit data format
• Accuracy Specification: ±0.51 PSI (±4.6 kPa) tolerance
• Supply Voltage Compatibility: 3.1V to 5.25V operating range
• Temperature Range: -40°C to 130°C operational capability
• Package Compatibility: 16-QFN Exposed Pad form factor with Surface Mount, Wettable Flank mounting
• Regulatory Compliance: ROHS3 and REACH compliance status

The FXPS7250DI4ST1 qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status (active versus obsolete) and packaging format (Tape & Reel versus individual unit).

Parameter Comparison

Engineering Selection Recommendations

The FXPS7250DI4ST1 is the direct active equivalent for the obsolete FXPS7250DI4T1. Both parts maintain identical electrical performance specifications, package geometry, and regulatory compliance certifications. The FXPS7250DI4ST1 is currently in active production status with confirmed inventory availability.

Selection of the FXPS7250DI4ST1 is appropriate for new designs and production continuity where the FXPS7250DI4T1 is no longer available. The substitute part satisfies all functional and mechanical requirements established by the original specification. The higher maximum pressure rating (44.61 PSI versus 6.38 PSI) of the substitute part does not affect compatibility within the specified operating pressure range of 2.9 to 36.26 PSI.

Both parts maintain ROHS3 compliance and identical moisture sensitivity classification, ensuring compatibility with existing assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the FXPS7250DI4ST1 be used as a direct replacement for the FXPS7250DI4T1?

A: Yes. The FXPS7250DI4ST1 is electrically and mechanically equivalent to the FXPS7250DI4T1 across all critical parameters including pressure range, I2C output, 32-bit resolution, accuracy, supply voltage, temperature range, and package configuration. The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel versus individual unit).

Q: What is the significance of the different maximum pressure ratings?

A: The FXPS7250DI4T1 specifies a maximum pressure of 6.38 PSI (44 kPa), while the FXPS7250DI4ST1 specifies 44.61 PSI (300 kPa). Both parts operate identically within the specified operating pressure range of 2.9 to 36.26 PSI (20 to 250 kPa). The higher maximum pressure rating of the substitute part indicates improved overpressure protection capability and does not affect functional performance within the operating specification.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the FXPS7250DI4T1 and FXPS7250DI4ST1 maintain identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 3 (168 Hours) classification. No additional qualification or testing is required when transitioning from the obsolete part to the active substitute.

Q: What packaging considerations apply to the FXPS7250DI4ST1?

A: The FXPS7250DI4ST1 is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments. The original FXPS7250DI4T1 was supplied as individual units. Both maintain the identical 16-QFN Exposed Pad package geometry and Surface Mount, Wettable Flank mounting configuration, ensuring compatibility with existing PCB designs and assembly equipment.
