HS1100 Humidity Sensor Equivalent & Substitute Parts

Part Overview

The HS1100 is a capacitive humidity sensor manufactured by TE Connectivity Measurement Specialties, designed for surface mount applications. This sensor measures humidity across the range of 1 to 99% RH with a capacitance output and ±2% RH accuracy. The device operates at 5V supply voltage with a 5-second response time. Finding equivalent or substitute parts becomes necessary when the HS1100 reaches end-of-life status, inventory depletion occurs, or specific application requirements necessitate alternative mounting configurations or electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

The HPP801A031 is identified as a substitute for the HS1100 based on the following shared electrical and mechanical parameters:

Common Parameters:

• Manufacturer: TE Connectivity Measurement Specialties
• Sensor Type: Humidity
• Humidity Range: 1 ~ 99% RH
• Output Type: Capacitance
• Accuracy: ±2% RH
• Operating Temperature: -40°C ~ 140°C

Differentiating Parameters: The HPP801A031 differs from the HS1100 in supply voltage (10V versus 5V), response time (3 s versus 5 s), mounting type (Through Hole versus Surface Mount), and packaging format (Tube versus standard packaging). These differences establish the HPP801A031 as a functional substitute when application requirements permit operation at 10V supply voltage and through-hole mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HS1100 and HPP801A031 depends on circuit design constraints and application requirements:

HS1100 Selection Criteria:

• Applications requiring 5V supply voltage operation
• Surface mount PCB assembly processes
• Standard response time tolerance of 5 seconds
• Current inventory availability of 16713 units

HPP801A031 Selection Criteria:

• Applications requiring 10V supply voltage operation
• Through-hole mounting assembly processes
• Faster response time requirement of 3 seconds
• ROHS3 compliance requirement
• Unlimited moisture sensitivity level tolerance
• Current inventory availability of 2400 units

Both parts maintain identical humidity measurement range (1 ~ 99% RH), capacitance output type, and ±2% RH accuracy specification. The HPP801A031 carries active product status and documented ROHS3 compliance certification, establishing its suitability for applications with regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the HPP801A031 directly replace the HS1100 in existing designs?

A: Direct replacement requires circuit modification. The HPP801A031 operates at 10V supply voltage compared to the HS1100's 5V requirement. Additionally, the HPP801A031 uses through-hole mounting while the HS1100 uses surface mount configuration. PCB redesign is necessary for mechanical and electrical compatibility.

Q: What is the significance of the 3-second versus 5-second response time difference?

A: The HPP801A031 provides a 2-second faster response time (3 s versus 5 s). This parameter determines how quickly the sensor detects and reports humidity changes. Applications requiring rapid humidity measurement response benefit from the HPP801A031's faster specification.

Q: Are both sensors suitable for the same temperature operating range?

A: Yes. Both the HS1100 and HPP801A031 operate across the identical temperature range of -40°C to 140°C, ensuring thermal compatibility across standard industrial and commercial applications.

Q: What does ROHS3 compliance indicate for the HPP801A031?

A: ROHS3 compliance certifies that the HPP801A031 meets Restriction of Hazardous Substances Directive requirements, restricting specific hazardous materials in electrical and electronic equipment. This certification is relevant for applications subject to European Union environmental regulations.

Q: How do the packaging formats differ between these sensors?

A: The HS1100 uses standard surface mount packaging for automated PCB assembly. The HPP801A031 is supplied in tube packaging and features through-hole mounting, requiring manual or selective soldering assembly processes.

Q: Do both sensors provide identical humidity measurement accuracy?

A: Yes. Both the HS1100 and HPP801A031 deliver ±2% RH accuracy across the 1 to 99% RH measurement range, ensuring equivalent measurement precision for humidity sensing applications.
