Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5525DSO-SB001GS is determined by alignment of critical electrical and mechanical parameters within the MS5525DSO series. The primary substitution candidate shares the following key parameters:

Matching Parameters:

• Manufacturer and series (TE Connectivity MS5525DSO)
• Operating pressure rating (1PSI / 6.89kPa)
• Digital output interfaces (I2C, SPI)
• Output resolution (24-bit)
• Accuracy specification (±0.25%)
• Supply voltage range (1.8V ~ 3.6V)
• Port configuration (Male - 0.12" barbed tube)
• Maximum pressure rating (20PSI / 137.9kPa)
• Operating temperature range (-40°C ~ 125°C)
• Package type (14-SMD Module)
• Termination style (Gull Wing)
• Temperature compensation feature
• MSL rating (3)

Differentiating Parameter:

• Pressure type: The main part is vented gauge; the substitute is differential

The substitute part 5525DSO-SB001DS maintains active product status and full electrical compatibility while differing only in pressure measurement type. This distinction is critical for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

The 5525DSO-SB001DS serves as the direct substitute for the obsolete 5525DSO-SB001GS based on active product status within the same manufacturer series and full alignment of electrical and mechanical specifications. The substitute maintains identical output interfaces, resolution, accuracy, voltage supply requirements, package configuration, and environmental operating parameters.

Selection between these parts depends exclusively on application pressure measurement requirements. The original part measures vented gauge pressure (referenced to atmospheric pressure through a vent), while the substitute measures differential pressure (referenced between two independent pressure inputs). Applications requiring vented gauge measurement cannot use the differential variant without circuit redesign. Conversely, applications requiring differential pressure measurement benefit from the active product status of the 5525DSO-SB001DS.

Both parts carry identical MSL ratings and comply with the same regulatory classifications (ECCN: EAR99; HTSUS: 9026.20.4000), ensuring equivalent handling and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5525DSO-SB001DS directly replace the 5525DSO-SB001GS in existing designs?

A: Direct replacement is possible only if the application does not depend on vented gauge pressure measurement. The substitute measures differential pressure instead of gauge pressure. If the original design requires gauge pressure measurement, circuit modifications are necessary to accommodate the differential measurement type.

Q: What is the difference between vented gauge and differential pressure measurement?

A: Vented gauge pressure is measured relative to atmospheric pressure through an internal vent. Differential pressure is measured as the difference between two independent pressure inputs. These measurement types produce different output values for the same physical pressure condition.

Q: Are the I2C and SPI output interfaces identical between both parts?

A: Yes. Both the 5525DSO-SB001GS and 5525DSO-SB001DS provide I2C and SPI digital output interfaces with 24-bit resolution. Firmware and software implementations for data communication are compatible.

Q: Do both parts have the same supply voltage requirements?

A: Yes. Both parts operate on 1.8V to 3.6V supply voltage with identical accuracy and temperature compensation characteristics across this range.

Q: What is the significance of the active product status for the 5525DSO-SB001DS?

A: Active product status indicates ongoing manufacturer support, availability through distribution channels, and continued compliance with current regulatory standards. The obsolete status of the original part means it is no longer manufactured and availability is limited to existing inventory.

Q: Are the physical packages and mounting requirements identical?

A: Yes. Both parts use 14-SMD surface mount modules with gull wing termination style and identical port configurations (male 0.12" barbed tube). PCB footprints and mounting procedures are compatible.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL rating 3 (168 hours), requiring identical moisture control and handling procedures during storage and assembly.
