SHT33-DIS-B10KS Equivalent & Substitute Parts

Part Overview

The SHT33-DIS-B10KS is a 3-point calibrated humidity and temperature sensor manufactured by Sensirion AG with ISO17025 certification. This surface mount component operates across a 0–100% RH humidity range with ±2% RH accuracy and provides digital output via I2C interface. The sensor is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Alternative part numbers are available to address specific application requirements or inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

The SHT33-DIS-B10KS has one parametric equivalent: SHT33-DIS-B2.5KS. Substitution eligibility is determined by the following criteria:

Substitution-Determining Parameters:

• Sensor Type (Humidity, Temperature)
• Humidity Range (0–100% RH)
• Output Type (I2C)
• Output Resolution (16-bit)
• Accuracy (±2% RH)
• Response Time (2 s)
• Supply Voltage Range (2.15V–5.5V)
• Operating Temperature Range (−40°C to +125°C)
• Mounting Type (Surface Mount)
• Package Type (8-VFDFN Exposed Pad)
• Compliance Status (RoHS3, REACH Unaffected)
• Moisture Sensitivity Level (1)

The substitute part SHT33-DIS-B2.5KS matches all electrical and mechanical parameters with the main part. The difference in part number designation reflects internal manufacturing or calibration variants that do not affect functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the SHT33-DIS-B10KS and SHT33-DIS-B2.5KS are active products from Sensirion AG with identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts should be based on:

Inventory Availability: The SHT33-DIS-B10KS maintains 10,812 units in stock, while the SHT33-DIS-B2.5KS has 5,867 units available. Choose based on procurement lead time requirements and supply chain strategy.

Compliance Requirements: Both parts satisfy RoHS3 and REACH requirements. Both carry ISO17025 3-point calibration certification. No compliance differentiation exists between the two options.

Application Compatibility: Identical I2C interface, 16-bit output resolution, ±2% RH accuracy, and 2-second response time ensure functional interchangeability in all circuit designs. Pin-to-pin compatibility and package dimensions (8-DFN 2.5×2.5 mm) are identical.

Moisture Handling: Both parts feature MSL 1 (unlimited) rating, eliminating moisture sensitivity constraints during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can SHT33-DIS-B2.5KS be used as a direct replacement for SHT33-DIS-B10KS in existing designs?

A: Yes. All electrical parameters, I2C communication protocol, output resolution, accuracy specifications, and physical package dimensions are identical. No circuit modifications or firmware changes are required.

Q: What is the difference between the B10KS and B2.5KS designations?

A: The part number suffix reflects internal manufacturing or calibration batch variants. Both parts meet identical functional and performance specifications as defined by Sensirion AG. The difference does not affect electrical or mechanical compatibility.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both the SHT33-DIS-B10KS and SHT33-DIS-B2.5KS operate across −40°C to +125°C, supporting industrial and extended temperature range applications.

Q: Do these sensors require different PCB layouts or footprints?

A: No. Both parts use the 8-VFDFN Exposed Pad package with identical 2.5×2.5 mm dimensions and pin configuration. PCB layouts are fully compatible.

Q: Which part should be selected for high-volume production?

A: Selection should be based on current inventory levels and supply chain availability. The SHT33-DIS-B10KS currently has higher stock (10,812 units). Consult with your supplier regarding lead times and production schedules for both variants.

Q: Are calibration certificates available for both parts?

A: Both parts carry 3-point calibration with ISO17025 certification. Calibration documentation should be requested from Sensirion AG or your authorized distributor.

Q: What is the moisture sensitivity level for both sensors?

A: Both parts have MSL 1 (Unlimited), meaning they can be stored and handled without moisture bake-out procedures prior to reflow soldering.
