SHT35A-DIS-B10KS Equivalent & Substitute Parts

Part Overview

The SHT35A-DIS-B10KS is an automotive-grade humidity and temperature sensor manufactured by Sensirion AG. This surface-mount component operates across a 0 to 100% RH humidity range with ±1.5% RH accuracy and provides digital output via I2C interface. The sensor is qualified to AEC-Q100 automotive standards and operates across an extended temperature range of -40°C to 125°C. The part is currently active in production with 804 units in stock. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and automotive qualification are maintained across the component family.

Substitute Part Grouping Explanation

Substitution eligibility for the SHT35A-DIS-B10KS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical sensor type (Humidity, Temperature)
• Matching humidity measurement range (0 ~ 100% RH)
• Identical output interface (I2C)
• Matching output resolution (16-bit)
• Identical accuracy specification (±1.5% RH)
• Identical response time (8 seconds)
• Matching supply voltage range (2.4V ~ 5.5V)
• Identical operating temperature range (-40°C ~ 125°C)

Mechanical & Compliance Equivalence Requirements:

• Identical mounting type (Surface Mount)
• Identical package specification (8-VFDFN Exposed Pad, 2.5x2.5)
• Same manufacturer (Sensirion AG)
• Same series designation (SHT3)
• Identical automotive grade and AEC-Q100 qualification
• Matching RoHS and REACH compliance status

The SHT35A-DIS-B10KS and SHT35A-DIS-B2.5KS are members of the same SHT3 series and share identical electrical and mechanical specifications. The difference in part number designation reflects packaging quantity variations (tape reel specifications) only, with no impact on component performance or compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SHT35A-DIS-B10KS and SHT35A-DIS-B2.5KS are active production components with full AEC-Q100 automotive qualification. Selection between these parts is based on supply chain availability and packaging requirements rather than functional performance.

The SHT35A-DIS-B10KS currently maintains 804 units in stock inventory. The SHT35A-DIS-B2.5KS provides higher inventory availability with 3,087 units in stock. Both components are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) ratings, indicating no special storage or handling requirements.

For applications requiring immediate component availability or high-volume procurement, the SHT35A-DIS-B2.5KS offers superior stock position. For applications with existing supply agreements or specific tape reel configurations, the SHT35A-DIS-B10KS remains a direct equivalent.

Both parts maintain identical electrical performance across the full automotive temperature range (-40°C to 125°C) and deliver equivalent I2C interface functionality with 16-bit resolution and ±1.5% RH accuracy.

Frequently Asked Questions (FAQ)

Q: Are the SHT35A-DIS-B10KS and SHT35A-DIS-B2.5KS electrically identical?

A: Yes. Both components deliver identical electrical performance including I2C output, 16-bit resolution, ±1.5% RH accuracy, 8-second response time, and 2.4V to 5.5V supply voltage operation. The part number suffix reflects packaging tape reel specifications only.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both components use identical 8-VFDFN surface-mount packages with 2.5x2.5mm dimensions and exposed pad configuration. PCB footprints, solder reflow profiles, and assembly processes are identical.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the SHT35A-DIS-B10KS and SHT35A-DIS-B2.5KS carry AEC-Q100 automotive qualification and are rated for -40°C to 125°C operating temperature. Both are ROHS3 compliant.

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

A: The suffix designates tape reel packaging specifications. The B10KS and B2.5KS variants differ in tape reel configuration and quantity per reel, not in component performance or specifications.

Q: Are there any moisture sensitivity or storage differences?

A: No. Both parts carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions and no special storage or handling requirements.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on supply chain availability, existing inventory positions, and packaging requirements. Both maintain active production status and full automotive qualification.
