HS3004 Humidity and Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The HS3004 is a surface-mount humidity and temperature sensor manufactured by Renesas Electronics Corporation, designed for applications requiring combined environmental monitoring. The sensor operates across a 0–100% RH range with I2C digital output and supports supply voltages from 1.8V to 5.5V. The HS3004 is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The HS3003 serves as the manufacturer-recommended alternative, offering improved accuracy specifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS3004 is determined by strict alignment of the following critical parameters:

• Sensor Type: Both humidity and temperature sensing capability required
• Humidity Range: Full 0–100% RH coverage mandatory
• Output Interface: I2C digital communication protocol
• Output Resolution: 14-bit data format
• Supply Voltage Range: 1.8V–5.5V compatibility
• Operating Temperature Range: −40°C to +125°C coverage
• Mounting Type: Surface mount configuration
• Package Specification: 6-VLGA (6-LGA 3×2.41 mm) form factor

The HS3003 meets all mandatory substitution criteria. While the HS3003 provides improved accuracy (±2.5% RH versus ±4.6% RH), all other electrical, mechanical, and interface parameters remain identical to the HS3004, ensuring direct functional replacement without circuit redesign.

Engineering Selection Recommendations

The HS3003 is the appropriate substitute for the obsolete HS3004 based on the following engineering criteria:

Product Status Alignment: The HS3003 maintains active product status with Renesas Electronics Corporation, ensuring continued availability, technical support, and manufacturing consistency. The HS3004 obsolescence status creates supply chain risk and limits access to updated documentation.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for current production environments.

Electrical and Mechanical Compatibility: The HS3003 provides identical supply voltage range (1.8V–5.5V), operating temperature range (−40°C to +125°C), I2C interface protocol, and 14-bit output resolution. No circuit modifications or firmware changes are required for substitution.

Performance Enhancement: The HS3003 delivers improved humidity accuracy (±2.5% RH) compared to the HS3004 (±4.6% RH), providing tighter measurement tolerance without additional design complexity.

Packaging Consistency: Both components use the 6-VLGA (6-LGA 3×2.41 mm) package, ensuring PCB layout compatibility and eliminating mechanical redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the HS3003 be used as a direct replacement for the HS3004 without PCB modifications?

A: Yes. The HS3003 and HS3004 share identical package geometry (6-VLGA 3×2.41 mm), pin configuration, supply voltage range (1.8V–5.5V), I2C interface protocol, and operating temperature range (−40°C to +125°C). No PCB layout changes or circuit redesign are necessary.

Q: What is the primary difference between the HS3004 and HS3003?

A: The HS3003 provides improved humidity measurement accuracy of ±2.5% RH compared to the HS3004's ±4.6% RH specification. All other functional parameters, including sensor type, output resolution (14-bit), response time (6 s), and environmental operating range, remain identical.

Q: Why is the HS3004 classified as obsolete?

A: The HS3004 has reached end-of-life status within Renesas Electronics Corporation's product portfolio. The HS3003 supersedes it as the current production alternative, offering equivalent functionality with enhanced accuracy specifications.

Q: Are there any firmware or software changes required when substituting the HS3003 for the HS3004?

A: No. Both components implement the same I2C communication protocol and 14-bit output format. Existing firmware and software drivers designed for the HS3004 operate without modification on the HS3003.

Q: Do the HS3003 and HS3004 have identical moisture sensitivity levels?

A: Yes. Both components carry an MSL (Moisture Sensitivity Level) rating of 3 with a 168-hour floor life specification, requiring identical handling and storage protocols during manufacturing and assembly.

Q: What is the humidity measurement range for both sensors?

A: Both the HS3004 and HS3003 measure humidity across the full 0–100% RH range with I2C digital output, supporting applications requiring comprehensive environmental monitoring.
