SHT10 Equivalent & Substitute Parts

Part Overview

The SHT10 is a humidity and temperature sensor manufactured by Sensirion, classified as an obsolete product. It provides digital output with 12-bit resolution and operates across a 0–100% RH range with ±4.5% RH accuracy. The sensor is housed in a 10-SMD Module package and supports supply voltages from 2.4V to 5.5V. Due to its obsolete status, equivalent substitute parts from the SHT3 series are available to maintain design continuity and ensure long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SHT10 is based on the following allowed parameters:

• Sensor Type: Humidity and Temperature measurement capability
• Humidity Range: Full 0–100% RH coverage
• Mounting Type: Surface Mount compatibility
• Voltage Supply: Overlap within 2.4V–5.5V range
• Operating Temperature: Coverage of −40°C to 123°C minimum
• RoHS and MSL Compliance: ROHS3 Compliant, MSL 1 rating
• Response Time: 8 s specification maintained

The SHT3 series substitutes meet these criteria. However, output type differs: the SHT10 provides digital output, while substitutes offer either I2C digital interface (SHT30-DIS variants) or analog voltage output (SHT30-ARP-B). These output differences require circuit-level evaluation during integration.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are manufactured by Sensirion AG and carry Active product status, ensuring long-term availability and supply chain stability. All substitutes maintain ROHS3 compliance and MSL 1 rating, matching the SHT10 environmental and regulatory requirements.

The SHT30-DIS series (SHT30-DIS-P2.5KS, SHT30-DIS-B2.5KS, SHT30-DIS-F2.5KS) provide I2C digital interface with 16-bit resolution and improved ±2% RH accuracy. These variants differ only in packaging format: Tape & Reel (TR) for P2.5KS and F2.5KS, and Cut Tape (CT) & Digi-Reel® for B2.5KS. Selection among these three depends on procurement and assembly requirements.

The SHT30-ARP-B provides analog voltage output with ±2% RH accuracy and Tape & Reel packaging. This variant is suitable for designs requiring analog signal conditioning rather than digital communication protocols.

All substitutes operate within the SHT10's voltage supply range and maintain the 8 s response time specification. Operating temperature range extends to 125°C, exceeding the SHT10's 123°C maximum. Package form factor changes from 10-SMD Module to 8-VFDFN Exposed Pad require PCB layout revision.

Frequently Asked Questions (FAQ)

Q: Can the SHT30-DIS series directly replace the SHT10 without circuit modification?

A: No. The SHT10 outputs digital signals via a proprietary interface, while SHT30-DIS variants use I2C protocol. Microcontroller firmware and signal conditioning circuits must be redesigned to accommodate I2C communication and 16-bit data format.

Q: What is the difference between SHT30-DIS-P2.5KS, SHT30-DIS-B2.5KS, and SHT30-DIS-F2.5KS?

A: These three parts are electrically identical. Differences exist only in packaging format: P2.5KS and F2.5KS are supplied in Tape & Reel (TR), while B2.5KS is supplied in Cut Tape (CT) & Digi-Reel®. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Is the SHT30-ARP-B suitable as a substitute if my design uses analog signal processing?

A: Yes. The SHT30-ARP-B provides analog voltage output with ±2% RH accuracy and maintains all environmental and compliance specifications of the SHT10. However, the output signal format differs; analog voltage conditioning circuits are required instead of digital interface circuits.

Q: Do all substitutes maintain the same operating temperature range as the SHT10?

A: The SHT10 operates from −40°C to 123°C. All SHT3 series substitutes extend this range to −40°C to 125°C, providing additional thermal margin. This is a functional improvement with no compatibility concerns.

Q: What is the impact of changing from 10-SMD Module to 8-VFDFN Exposed Pad packaging?

A: Package form factor change requires PCB layout revision, including footprint redesign, trace routing, and thermal management evaluation. The 8-VFDFN package is smaller and includes an exposed pad for improved thermal dissipation. Assembly process parameters may also require adjustment.

Q: Are all substitutes RoHS3 compliant and MSL 1 rated like the SHT10?

A: Yes. All SHT3 series substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the SHT10's environmental and regulatory certifications.
