A/RH5-20K-RO Humidity and Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The A/RH5-20K-RO is an active humidity and temperature sensor manufactured by Automation Components, Inc. This chassis-mounted module provides analog current and voltage outputs for relative humidity measurement across the 0 to 100% RH range with ±5% accuracy and a 20-second response time. The part operates on dual voltage supplies (18–28VAC or 12–40VDC) and is currently in active production status with 836 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the A/RHx sensor series, enabling direct replacement in applications where packaging or operating temperature ranges do not impose additional constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A/RH5-20K-RO is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters (Must Match):

• Humidity measurement range: 0 ~ 100% RH
• Output type: Analog Current and Analog Voltage
• Output signal levels: 0V ~ 5V, 0V ~ 10V, 4mA ~ 20mA
• Measurement accuracy: ±5% RH
• Response time: 20 seconds
• Supply voltage compatibility: 18 ~ 28VAC, 12 ~ 40VDC

Core Mechanical Parameters (Must Match):

• Mounting configuration: Chassis Mount
• Package form factor: Module

Variable Parameters (Allowed to Differ):

• Operating temperature range (provided the application temperature falls within the substitute's range)
• Packaging format (Tape & Box vs. Module packaging)
• Series designation (A/RHx-20K, A/RHx-AN, A/RHx-CP)

All substitute parts listed maintain identical sensor type, humidity range, output type, accuracy, response time, voltage supply, and mounting type. Differences in operating temperature range and packaging format do not affect functional substitution when application requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and are functionally equivalent to the A/RH5-20K-RO across core electrical and mechanical specifications. Selection among substitutes is based on the following criteria:

Operating Temperature Requirement:

• For applications operating within 1.5°C to 60°C: A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, A/RH5-AN-RSO-A03-A1, A/RH5-CP-R, and A/RH5-CP-R2 are suitable.
• For applications requiring extended low-temperature operation (-40°C to 60°C): A/RH5-AN-D and A/RH5-CP-D are suitable.

Packaging Format:

• Module packaging (standard): A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, A/RH5-AN-RSO-A03-A1, A/RH5-CP-R, A/RH5-CP-R2
• Tape & Box packaging: A/RH5-AN-D, A/RH5-CP-D

Inventory Availability:

• Highest stock levels: A/RH5-AN-R2O (1084 Pcs), A/RH5-AN-RSO-A03-A1 (1076 Pcs), A/RH5-CP-R2 (840 Pcs)

All parts are manufactured by Automation Components, Inc. and carry active product status, ensuring continued support and availability.

Frequently Asked Questions (FAQ)

Q: Can A/RH5-AN-D substitute for A/RH5-20K-RO in all applications?

A: A/RH5-AN-D is electrically and mechanically equivalent but differs in two aspects: operating temperature range (-40°C to 60°C versus 1.5°C to 60°C) and packaging format (Tape & Box versus Module). If your application operates within 1.5°C to 60°C and Module packaging is required, A/RH5-AN-D is suitable. If extended low-temperature operation is needed, A/RH5-AN-D provides additional capability.

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

A: Both series maintain identical electrical parameters (humidity range, output type, accuracy, response time, supply voltage) and mounting type. The series designation reflects internal design or configuration differences that do not affect functional substitution. Selection between series is based on operating temperature range and packaging availability.

Q: Does packaging format affect electrical performance?

A: No. Module and Tape & Box packaging formats contain identical sensor and output electronics. Packaging format affects only handling, storage, and installation procedures. Electrical performance and output specifications remain unchanged.

Q: Which substitute part has the highest inventory availability?

A: A/RH5-AN-R2O has the highest inventory with 1084 units in stock, followed by A/RH5-AN-RSO-A03-A1 with 1076 units.

Q: Are all substitute parts currently in active production?

A: Yes. All listed substitute parts carry active product status, ensuring continued manufacturing support and availability.

Q: Can I use A/RH5-CP-D in applications requiring Module packaging?

A: A/RH5-CP-D is supplied in Tape & Box packaging. If your application specifically requires Module packaging format, select from A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, A/RH5-AN-RSO-A03-A1, A/RH5-CP-R, or A/RH5-CP-R2.

Q: What is the response time for all substitute parts?

A: All substitute parts maintain a 20-second response time, identical to the A/RH5-20K-RO.
