HS4014 Humidity and Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The HS4014 is a combined humidity and temperature sensor manufactured by Renesas Electronics Corporation, designed for applications requiring simultaneous measurement of relative humidity and ambient temperature. The device features I2C digital output with 14-bit resolution and operates across a wide humidity range of 0 to 100% RH with ±3.5% RH accuracy. The HS4014 is classified as Last Time Buy, indicating discontinued production status. Identification of equivalent substitute parts is necessary to ensure continued component availability for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS4014 is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Sensor Type: Humidity and Temperature measurement capability
• Output Type: I2C digital interface
• Output Resolution: 14-bit data format
• Accuracy: ±3.5% RH specification
• Response Time: 4-second measurement cycle

Electrical Parameters:

• Supply Voltage Range: 1.71V ~ 3.6V
• Operating Temperature Range: -40°C ~ 125°C

Physical and Packaging Parameters:

• Mounting Type: Surface Mount
• Package / Case: 8-VFDFN Exposed Pad
• Supplier Device Package: 8-LGA (2.5x2.5)
• Moisture Sensitivity Level: 3 (168 Hours)
• Packaging Format: Tape & Reel (TR)

Measurement Capability:

• Humidity Range: 0 ~ 100% RH

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The HS4004 is a direct parametric equivalent to the HS4014 across all specified electrical, functional, and physical parameters. Both devices share identical sensor type, I2C output interface, 14-bit resolution, ±3.5% RH accuracy, 4-second response time, supply voltage range, operating temperature range, and package specifications.

The primary distinction between these parts is product lifecycle status: the HS4014 is designated Last Time Buy, indicating end-of-life production, while the HS4004 maintains Active status with ongoing manufacturing and availability. Both devices are manufactured by Renesas Electronics Corporation within the same sensor series family (HS401x and HS400x respectively).

For applications currently using the HS4014, the HS4004 provides full functional and electrical compatibility without design modification. The identical package footprint (8-VFDFN Exposed Pad, 8-LGA 2.5x2.5) and MSL rating (3, 168 Hours) ensure direct PCB-level compatibility. No firmware, software, or protocol changes are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the HS4004 be used as a direct replacement for the HS4014 in existing designs?

A: Yes. The HS4004 is a parametric equivalent with identical electrical specifications, I2C protocol implementation, 14-bit output format, accuracy rating, response time, supply voltage requirements, operating temperature range, and physical package dimensions. No design modifications are necessary.

Q: Are there any differences in I2C communication protocol between the HS4014 and HS4004?

A: Both devices implement I2C digital output with 14-bit resolution. The provided parameters confirm identical output type and resolution specifications. No protocol differences are indicated in the supplied technical parameters.

Q: What is the significance of the different series designations (HS401x vs HS400x)?

A: The HS4014 belongs to the HS401x series while the HS4004 belongs to the HS400x series. Both are Renesas humidity and temperature sensor families with equivalent functional and electrical specifications. The series designation reflects product line organization rather than functional capability differences.

Q: Is the package footprint identical between these two parts?

A: Yes. Both the HS4014 and HS4004 use the 8-VFDFN Exposed Pad package with 8-LGA (2.5x2.5) supplier device package specification. PCB layout and reflow soldering parameters remain unchanged.

Q: What does the Last Time Buy status of the HS4014 mean for component sourcing?

A: Last Time Buy designation indicates that the HS4014 has reached end-of-life production. Existing inventory may be limited, and future availability cannot be guaranteed. The HS4004, with Active product status, represents the recommended alternative for new designs and ongoing production requirements.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both devices specify MSL 3 (168 Hours), indicating identical moisture handling and storage requirements. Standard moisture control procedures for MSL 3 components apply to both parts.

Q: Can these parts be used interchangeably in production?

A: Yes. The HS4004 provides full electrical, functional, and physical compatibility with the HS4014. Both devices meet identical accuracy, response time, and environmental specifications. Production line substitution requires no process changes.
