HS3102-ML1 Equivalent & Substitute Parts Reference

Part Overview

The HS3102-ML1 is a humidity and temperature sensor module manufactured by Renesas Electronics Corporation. This integrated circuit module combines dual sensing functionality with I2C digital output, designed for applications requiring simultaneous environmental monitoring across a wide humidity range (0 to 100% RH) and extended temperature operating window (-40°C to 125°C). The HS3102-ML1 is classified as an obsolete product status, necessitating identification of active equivalent alternatives to ensure design continuity and supply chain reliability for new production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS3102-ML1 is determined by strict compliance with the following critical parameters:

Mandatory Matching Parameters:

• Sensor Type: Humidity and Temperature dual sensing
• Output Interface: I2C digital communication protocol
• Output Resolution: 14-bit data format
• Humidity Range: 0 to 100% RH full-scale coverage
• Response Time: 6 seconds
• Supply Voltage Range: 2.3V to 5.5V compatibility
• Operating Temperature Range: -40°C to 125°C
• Mounting Type: Through Hole configuration
• Package Type: 4-SIP Module form factor

Acceptable Variation Parameter:

• Humidity Accuracy: Tolerance specifications may vary within engineering acceptable limits, provided the substitute part maintains equal or superior accuracy performance

The HS3101-ML1 qualifies as a direct substitute based on full compliance with all mandatory parameters while offering improved humidity accuracy specification (±1.5% RH versus ±1.8% RH).

Engineering Selection Recommendations

The HS3101-ML1 is the designated active substitute for the obsolete HS3102-ML1. Selection of the HS3101-ML1 is based on the following engineering criteria:

Product Status Compliance: The HS3101-ML1 maintains active product status with Renesas Electronics Corporation, ensuring ongoing manufacturing support, supply chain availability, and technical documentation accessibility. The HS3102-ML1 obsolete status creates supply risk and limits access to manufacturer support resources.

Functional Equivalence: Both parts operate within the HS310x-ML1 series architecture and share identical electrical and mechanical specifications across all critical parameters. The I2C interface, 14-bit output resolution, and environmental operating ranges are fully compatible.

Performance Enhancement: The HS3101-ML1 provides superior humidity accuracy specification (±1.5% RH) compared to the HS3102-ML1 (±1.8% RH), representing a 16.7% improvement in measurement precision without any corresponding performance degradation in other parameters.

Physical Compatibility: Identical 4-SIP Module packaging and through-hole mounting configuration ensure direct mechanical and electrical interchangeability in existing PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the HS3101-ML1 be used as a direct replacement for HS3102-ML1 in existing designs?

A: Yes. The HS3101-ML1 is electrically and mechanically compatible with the HS3102-ML1. Both parts share identical I2C interface protocols, 14-bit output format, supply voltage requirements (2.3V to 5.5V), operating temperature range (-40°C to 125°C), and 4-SIP Module package configuration. No PCB modifications or firmware changes are required.

Q: What is the difference in humidity accuracy between these two parts?

A: The HS3102-ML1 specifies ±1.8% RH accuracy, while the HS3101-ML1 specifies ±1.5% RH accuracy. The HS3101-ML1 provides improved measurement precision. Both accuracies cover the full 0 to 100% RH humidity range.

Q: Why is the HS3102-ML1 classified as obsolete?

A: The HS3102-ML1 has reached end-of-life status with Renesas Electronics Corporation. The manufacturer has transitioned production to the HS3101-ML1, which offers equivalent functionality with enhanced accuracy specifications. Obsolete classification indicates that new manufacturing runs are no longer available, though existing inventory may remain available through authorized distributors.

Q: Are there any firmware or software compatibility issues when switching from HS3102-ML1 to HS3101-ML1?

A: No. Both parts implement identical I2C communication protocols and 14-bit output data formats. Existing firmware and software drivers designed for the HS3102-ML1 operate without modification on the HS3101-ML1.

Q: What is the current inventory status for the HS3101-ML1?

A: The HS3101-ML1 maintains active production status with 849 pieces of new original stock currently available through authorized Renesas distributors.

Q: Can the HS3101-ML1 be used in applications originally designed for the HS3102-ML1 without design review?

A: Yes. The HS3101-ML1 meets or exceeds all electrical and mechanical specifications of the HS3102-ML1. The improved accuracy specification represents a performance enhancement rather than a limitation. Direct substitution is appropriate for all applications within the specified operating parameters.
