HS4011 Equivalent & Substitute Parts

Part Overview

The HS4011 is a surface mount humidity and temperature sensor manufactured by Renesas Electronics Corporation. This component integrates relative humidity measurement across the 0–100% RH range with temperature sensing capability, communicating via I2C interface. The HS4011 operates within a supply voltage range of 1.71V to 3.6V and maintains ±1.5% RH accuracy with a 4-second response time across an operating temperature range of -40°C to 125°C. The device is packaged in an 8-VFDFN exposed pad configuration (8-LGA 2.5x2.5mm) and is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component interchangeability in designs requiring humidity and temperature sensing functionality.

Substitute Part Grouping Explanation

Substitute parts for the HS4011 are identified based on matching electrical and mechanical parameters that define functional equivalence. The primary substitution criteria are:

Electrical Parameters:

• Humidity measurement range: 0–100% RH
• Output interface: I2C protocol
• Output resolution: 14-bit
• Humidity accuracy: ±1.5% RH
• Response time: 4 seconds
• Supply voltage range: 1.71V–3.6V
• Operating temperature range: -40°C–125°C

Mechanical Parameters:

• Mounting type: Surface Mount
• Package type: 8-VFDFN Exposed Pad
• Physical footprint: 8-LGA (2.5x2.5mm)
• Moisture sensitivity level: MSL 3 (168 Hours)

The HS4001 and HS4003 satisfy all electrical and mechanical equivalence criteria. Both devices operate within identical supply voltage, temperature, and humidity ranges, provide I2C output with 14-bit resolution, maintain ±1.5% RH accuracy, and share the same 4-second response time. Both are packaged in the 8-VFDFN exposed pad configuration with matching MSL ratings. Packaging format differences (Cut Tape & Digi-Reel® for HS4011 and HS4003; Tape & Reel for HS4001) do not affect electrical or mechanical compatibility and represent supply chain variations only.

Parameter Comparison

Engineering Selection Recommendations

All three devices—HS4011, HS4001, and HS4003—are classified as Active product status, indicating ongoing manufacturer support and availability. Component selection among these equivalents is determined by packaging format availability and regulatory compliance requirements.

HS4011: Supplied in Cut Tape (CT) & Digi-Reel® packaging format. ROHS3 compliant. Suitable for applications requiring tape-and-reel supply chain formats with RoHS3 certification requirements.

HS4001: Supplied in Tape & Reel (TR) packaging format. RoHS status not specified in provided data. Suitable for high-volume production environments utilizing standard tape-and-reel handling equipment.

HS4003: Supplied in Cut Tape (CT) & Digi-Reel® packaging format. ROHS3 compliant. Suitable for applications requiring cut tape supply with RoHS3 certification requirements.

All three devices maintain identical electrical performance characteristics, including I2C interface, 14-bit resolution, ±1.5% RH accuracy, and 4-second response time. Selection between HS4011 and HS4003 depends on packaging availability and inventory status. Selection of HS4001 is appropriate when Tape & Reel format is required and RoHS3 compliance is not a design constraint.

Frequently Asked Questions (FAQ)

Q: Can HS4001, HS4003, and HS4011 be used interchangeably in the same circuit design?

A: Yes. All three devices share identical electrical parameters including I2C interface, 14-bit output resolution, ±1.5% RH accuracy, 4-second response time, and 1.71V–3.6V supply voltage range. The 8-VFDFN exposed pad package and 8-LGA (2.5x2.5mm) footprint are identical across all three parts. No circuit modifications are required for substitution.

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

A: Cut Tape & Digi-Reel® and Tape & Reel are supply chain packaging formats that do not affect component electrical or mechanical performance. Cut Tape format is suitable for lower-volume applications and manual assembly. Tape & Reel format is optimized for automated pick-and-place equipment in high-volume production. Component functionality remains identical regardless of packaging format.

Q: Are all three parts RoHS3 compliant?

A: HS4011 and HS4003 are specified as ROHS3 compliant. HS4001 RoHS status is not specified in the provided data. Applications requiring RoHS3 certification should utilize HS4011 or HS4003.

Q: Do these devices require different PCB footprints?

A: No. All three devices use the 8-VFDFN exposed pad package with 8-LGA (2.5x2.5mm) footprint. A single PCB design accommodates all three part numbers without layout modifications.

Q: What is the Moisture Sensitivity Level (MSL) rating, and does it affect substitution?

A: All three devices are rated MSL 3 (168 Hours), indicating identical moisture sensitivity and storage requirements. No substitution constraints exist based on MSL rating.

Q: Can I substitute these parts based on supply availability?

A: Yes. Provided that packaging format and regulatory compliance requirements are satisfied, any of the three devices can be selected based on current inventory availability and lead time considerations. Electrical and mechanical compatibility is maintained across all substitutions.
