SEN-10167 Equivalent & Substitute Parts

Part Overview

The SEN-10167 is a humidity and temperature sensor manufactured by SparkFun Electronics, designed for digital output applications with ±2% RH accuracy across a 0–100% RH range. This component operates on 3.3V to 6V supply voltage and features through-hole mounting for integration into embedded systems and environmental monitoring applications.

The SEN-10167 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SEN-10167 is determined by the following critical parameters:

• Sensor Type: Must provide humidity and temperature measurement capability
• Humidity Range: Must cover 0–100% RH
• Mounting Type: Must support through-hole installation for PCB integration
• Operating Temperature Range: Must encompass -40°C to 80°C
• Supply Voltage Compatibility: Must operate within or overlap the 3.3V–6V range
• Output Protocol: Digital output formats (including I2C) are acceptable for digital sensor applications
• Accuracy: Tolerance specifications must be documented and suitable for the application

The SEN-18364 meets these substitution criteria as an active product offering equivalent humidity and temperature sensing with compatible mounting, operating range, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The SEN-18364 is an active product offering from SparkFun Electronics and serves as the designated substitute for the obsolete SEN-10167. Both components share identical humidity measurement ranges, operating temperature specifications, and through-hole mounting configurations.

Key differences requiring design consideration:

• Output Protocol: The SEN-18364 uses I2C communication instead of direct digital output. Firmware or microcontroller interface modifications may be required to accommodate serial communication protocols.
• Accuracy: The SEN-18364 specifies ±3% RH accuracy compared to ±2% RH for the SEN-10167. Applications requiring ±2% RH precision must evaluate whether the reduced accuracy is acceptable.
• Supply Voltage Range: The SEN-18364 operates from 2.2V–5.5V, which overlaps with the SEN-10167 range but has a lower minimum threshold. Existing 3.3V–6V supply designs remain compatible.
• Package Form Factor: The SEN-18364 is packaged as a 4-SIP module, differing from the housed sensor configuration of the SEN-10167. PCB layout and mechanical mounting must be verified for compatibility.
• RoHS Compliance: The SEN-10167 is ROHS3 compliant; the SEN-18364 status is not applicable. Regulatory requirements should be confirmed for the target application.

Frequently Asked Questions (FAQ)

Q: Can the SEN-18364 directly replace the SEN-10167 without design modifications?

A: Physical and electrical compatibility exists; however, the I2C output protocol of the SEN-18364 requires firmware changes compared to the direct digital output of the SEN-10167. PCB layout adjustments may also be necessary due to different package form factors.

Q: What is the impact of the ±3% RH accuracy specification on the SEN-18364 versus the ±2% RH of the SEN-10167?

A: The SEN-18364 has a 1% RH wider tolerance band. Applications with strict humidity measurement requirements must evaluate whether this specification change affects system performance or regulatory compliance.

Q: Are both parts compatible with 5V supply designs?

A: Yes. Both the SEN-10167 (3.3V–6V) and SEN-18364 (2.2V–5.5V) operate within 5V supply specifications. Designs using 3.3V supplies are also compatible with both components.

Q: What is the response time difference between these sensors?

A: The SEN-18364 specifies an 8-second response time. The SEN-10167 response time is not provided in the available specifications. Applications with time-critical measurements should confirm response time requirements independently.

Q: Is the SEN-18364 suitable for applications requiring ROHS3 compliance?

A: The SEN-18364 RoHS status is listed as not applicable. Designs requiring ROHS3 certification must verify compliance status with the manufacturer or select alternative components with explicit ROHS3 certification.
