SHT35-DIS-B10KS Equivalent & Substitute Parts

Part Overview

The SHT35-DIS-B10KS is an active, automotive-grade humidity and temperature sensor manufactured by Sensirion AG. This Surface Mount Device (SMD) integrates dual sensing capability with I2C digital output, operating across a 0–100% RH humidity range and -40°C to 125°C temperature range. The part is qualified to AEC-Q100 automotive standards and maintains ROHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across the SHT3 series, allowing for design flexibility, supply chain optimization, and inventory management without compromising functional requirements.

• Product Status: Active

The substitute parts differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability, with no impact on electrical performance or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SHT35-DIS-B10KS, SHT35-DIS-B2.5KS, and SHT35-DIS-F2.5KS—are active products within the Sensirion SHT3 series and maintain identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements rather than functional performance.

SHT35-DIS-B10KS is supplied in Tape & Reel (TR) format with 9905 units in stock. This packaging is standard for automated assembly processes requiring continuous reel feed.

SHT35-DIS-B2.5KS is supplied in Tape & Reel (TR) format with 2000 units in stock. This part is functionally equivalent to the main part number with identical electrical performance and mechanical fit.

SHT35-DIS-F2.5KS is supplied in Cut Tape (CT) & Digi-Reel® format with 114331 units in stock. This packaging option provides the highest inventory availability and is suitable for applications requiring flexible quantity procurement or manual assembly processes.

All three parts comply with ROHS3, maintain REACH Unaffected status, and carry unlimited moisture sensitivity level (MSL 1) rating. Selection should be based on assembly process requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SHT35-DIS-B2.5KS or SHT35-DIS-F2.5KS be used as direct replacements for SHT35-DIS-B10KS in existing designs?

A: Yes. Both substitute parts maintain identical electrical performance, mechanical fit, and compliance certifications. The only differences are packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory levels. PCB layout, firmware, and system integration require no modification.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components in cut tape format with optional reel configuration, offering flexibility for lower-volume or mixed-assembly processes.

Q: Are all three parts automotive-grade qualified?

A: The SHT35-DIS-B10KS is specified as automotive-grade with AEC-Q100 qualification. The SHT35-DIS-B2.5KS and SHT35-DIS-F2.5KS do not list automotive grade or AEC-Q100 qualification in their specifications. For automotive applications requiring AEC-Q100 certification, SHT35-DIS-B10KS is the specified part.

Q: Do these parts have identical I2C communication protocols?

A: Yes. All three parts use I2C digital output with 16-bit resolution, identical supply voltage range (2.15V–5.5V), and identical operating temperature range (-40°C to 125°C). No firmware or protocol changes are required when substituting between these parts.

Q: What is the significance of the 8-DFN (2.5x2.5) package designation?

A: This specifies the physical footprint and pin configuration. All three parts use the same 8-pin Dual Flat No-lead (DFN) package with 2.5mm × 2.5mm dimensions. PCB footprints and solder reflow profiles are identical across all three parts.

Q: Which part should be selected for maximum supply availability?

A: SHT35-DIS-F2.5KS offers the highest inventory level at 114331 units. This part is suitable for applications where supply chain flexibility and availability are primary considerations.

Q: Are there any differences in humidity or temperature measurement accuracy between these parts?

A: No. All three parts maintain ±1.5% RH accuracy across the 0–100% RH humidity range and -40°C to 125°C operating temperature range with 8-second response time.
