Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTU31D 10142048-02 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Sensor Type: Humidity, Temperature
• Humidity Range: 0 ~ 100% RH
• Output Type: Digital, I2C
• Accuracy: ±2% RH
• Response Time: 5 s
• Voltage Supply: 3V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C
• Mounting Type: Surface Mount
• Package / Case: 6-VDFN Exposed Pad
• Supplier Device Package: 6-DFN (2.5x2.5)
• Series: HTU31
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 10142048-22 satisfies all mandatory matching parameters. The primary distinction between the main part and its substitute is product status (obsolete versus active) and packaging configuration (bulk versus tape & reel).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity HTU31D 10142048-22 is the direct functional equivalent for applications currently specified with part number 10142048-02.

Compliance and Status Considerations:

The 10142048-02 carries obsolete product status, indicating discontinued manufacturing and limited long-term availability. The substitute part 10142048-22 maintains active product status with TE Connectivity Measurement Specialties, ensuring ongoing supply chain access and manufacturing support.

Both parts maintain identical ROHS3 compliance and Moisture Sensitivity Level (MSL) 1 rating, confirming equivalent environmental and regulatory standing. The ECCN classification (EAR99) and HTSUS code (9025.80.1000) remain consistent across both variants.

Packaging Distinction:

The primary operational difference is packaging configuration. The 10142048-02 is supplied in bulk form, while the 10142048-22 is supplied in Tape & Reel (TR) format. This distinction affects procurement, handling, and automated assembly processes but does not alter electrical or thermal performance characteristics.

For new designs, production ramp-up, or inventory replenishment, the 10142048-22 is the appropriate selection. For existing applications with established supply chains using bulk packaging, transition planning to the tape & reel format may be required.

Frequently Asked Questions (FAQ)

Q: Are the HTU31D 10142048-02 and 10142048-22 electrically identical?

A: Yes. Both parts share identical electrical specifications including I2C output protocol, ±2% RH accuracy, 5-second response time, 3V–5.5V supply voltage range, and -40°C to 125°C operating temperature. Pin configuration and package footprint (6-DFN 2.5x2.5) are identical.

Q: What is the significance of the product status difference?

A: The 10142048-02 is classified as obsolete, indicating TE Connectivity has discontinued active manufacturing. The 10142048-22 maintains active status, ensuring continued availability, technical support, and manufacturing consistency. For long-term production requirements, the active part is the appropriate selection.

Q: Can I use 10142048-22 as a direct replacement in existing PCB designs?

A: Yes. The 6-VDFN Exposed Pad package and pin configuration are identical. No PCB layout modifications are required. The substitute part is mechanically and electrically compatible with existing designs.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging supplies components in loose form, suitable for manual assembly or small-volume production. Tape & Reel (TR) packaging supplies components on continuous carrier tape within a reel, optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging affects handling and assembly methodology only.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and identical ECCN and HTSUS classifications. Regulatory and environmental standing is equivalent.

Q: Should I transition existing inventory to the substitute part?

A: Transition decisions depend on production volume, assembly methodology, and supply chain strategy. For automated assembly operations, Tape & Reel format (10142048-22) offers operational efficiency. For manual or low-volume assembly, bulk format may remain suitable until inventory depletion. Both parts are functionally equivalent for application performance.
