A/RH5-CP-R2L Humidity and Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The A/RH5-CP-R2L is an active product humidity and temperature sensor manufactured by Automation Components, Inc. This chassis-mounted module provides dual analog outputs (current and voltage) for relative humidity measurement across the 0 to 100% RH range with ±5% RH accuracy. The sensor operates with supply voltages of 18–28VAC or 12–40VDC and delivers a 20-second response time, making it suitable for industrial environmental monitoring and control applications. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative packaging, series designations, or operating temperature ranges better serve specific application constraints.

Substitute Part Grouping Explanation

Substitute parts for the A/RH5-CP-R2L are classified based on strict electrical and mechanical parameter equivalence. All substitute candidates maintain identical sensor type, humidity range, output type, output signals, accuracy, response time, supply voltage, and mounting type specifications. Substitution logic is organized into two primary categories:

Series A/RHx-CP (Chassis Mount, Connector-based): Parts A/RH5-CP-D, A/RH5-CP-R, and A/RH5-CP-R2 share the same series designation and connector-based architecture as the main part. These differ only in packaging format (Tape & Box versus module supplier packaging) and operating temperature range extensions.

Series A/RHx-AN (Chassis Mount, Alternative Configuration): Parts A/RH5-AN-D, A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, and A/RH5-AN-RSO-A03-A1 maintain all critical electrical parameters but represent an alternative series designation within the same product family. These parts are functionally equivalent for humidity and temperature measurement applications.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and are manufactured by Automation Components, Inc., ensuring consistent quality and support. Selection between the A/RH5-CP-R2L and its substitutes depends on application-specific requirements:

For applications requiring extended low-temperature operation (-40°C): Select A/RH5-CP-D or A/RH5-AN-D. Both parts extend the lower operating temperature limit from 1.5°C to -40°C while maintaining all other electrical specifications.

For applications within the standard operating temperature range (1.5°C ~ 60°C) with identical series requirements: Select A/RH5-CP-R or A/RH5-CP-R2. Both maintain the A/RHx-CP series designation and differ only in packaging format (Tape & Box versus module supplier packaging).

For applications within the standard operating temperature range with alternative series configuration: Select from A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, or A/RH5-AN-RSO-A03-A1. These A/RHx-AN series parts provide equivalent electrical performance with alternative connector or configuration options.

Packaging considerations: The main part A/RH5-CP-R2L is supplied in module format. Substitutes A/RH5-CP-R and A/RH5-CP-R2 are supplied in Tape & Box (TB) packaging, suitable for high-volume assembly operations. All A/RHx-AN series substitutes are also supplied in Tape & Box (TB) format.

Frequently Asked Questions (FAQ)

Q: Can A/RH5-CP-R2L be directly replaced with A/RH5-CP-R or A/RH5-CP-R2?

A: Yes. A/RH5-CP-R and A/RH5-CP-R2 are direct electrical and mechanical equivalents within the same A/RHx-CP series. The primary difference is packaging format: the main part uses module supplier packaging, while the substitutes use Tape & Box (TB) format. Operating temperature range remains identical at 1.5°C ~ 60°C.

Q: What is the difference between A/RHx-CP and A/RHx-AN series parts?

A: Both series maintain identical electrical specifications for humidity measurement, output types, accuracy, response time, and supply voltage. The series designation indicates alternative connector or configuration architectures. Selection between series depends on system integration requirements and connector compatibility.

Q: Can I use A/RH5-CP-D or A/RH5-AN-D in applications requiring operation below 0°C?

A: A/RH5-CP-D and A/RH5-AN-D extend the lower operating temperature limit to -40°C, making them suitable for cold environment applications. All other electrical parameters remain equivalent to the main part. Verify that your application's humidity measurement requirements remain within 0 ~ 100% RH at the extended temperature range.

Q: Are all substitute parts in active product status?

A: Yes. All listed substitute parts maintain active product status with Automation Components, Inc., ensuring continued availability and technical support.

Q: What packaging format should I select for high-volume manufacturing?

A: Tape & Box (TB) packaging is standard for high-volume assembly operations. A/RH5-CP-R, A/RH5-CP-R2, and all A/RHx-AN series parts are supplied in Tape & Box format. The main part A/RH5-CP-R2L uses module supplier packaging, suitable for lower-volume or direct integration scenarios.

Q: Do all substitute parts support the same output signal ranges?

A: Yes. All substitute parts support identical output signal ranges: 0V ~ 5V, 0V ~ 10V, and 4mA ~ 20mA. Output configuration selection depends on your system's analog input requirements and is independent of part number selection.

Q: Can I mix A/RHx-CP and A/RHx-AN series parts in the same system?

A: Yes, provided that connector and configuration compatibility is verified for your specific application. Both series maintain identical electrical performance for humidity and temperature measurement. Consult system integration documentation to confirm mechanical and electrical interface compatibility.
