A/RH5-CP-RS-A01-C5 Humidity and Temperature Sensor Module: Equivalent and Substitute Parts

Part Overview

The A/RH5-CP-RS-A01-C5 is an active humidity and temperature sensor module manufactured by Automation Components, Inc. This chassis-mounted module provides dual analog outputs (current and voltage) for relative humidity measurement across the 0–100% RH range with ±5% RH accuracy. The sensor operates across a supply voltage range of 18–28VAC or 12–40VDC and delivers a 20-second response time, making it suitable for industrial control and monitoring applications requiring integrated humidity and temperature sensing. The product maintains active status with 863 units in current inventory.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for assembly processes, or when extended operating temperature ranges are needed for specific environmental conditions.

Engineering Selection Recommendations

All substitute parts listed maintain active product status with Automation Components, Inc. and are manufactured to identical electrical and functional specifications as the primary part A/RH5-CP-RS-A01-C5.

Selection Criteria Based on Application Requirements:

For Standard Operating Conditions (1.5°C–60°C): Parts A/RH5-CP-R, A/RH5-CP-R2, A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, and A/RH5-AN-RSO-A03-A1 are direct functional equivalents. These parts differ only in packaging format (Tape & Box) and series designation. Selection among these options depends on assembly process requirements and inventory availability.

For Extended Temperature Operation (–40°C–60°C): Parts A/RH5-CP-D and A/RH5-AN-D provide expanded operating temperature range capability. These parts are suitable for applications requiring operation below 1.5°C or for systems designed with thermal margin specifications.

Packaging Considerations: The primary part A/RH5-CP-RS-A01-C5 is supplied in standard module packaging. All substitute parts are available in Tape & Box (TB) format, which is compatible with automated assembly equipment and tape-and-reel handling systems.

Inventory Availability: Current stock levels range from 750 to 1084 units across all substitute options, ensuring supply continuity for production requirements.

Frequently Asked Questions (FAQ)

Q1: Can A/RH5-AN series parts substitute for A/RH5-CP series parts?

A: Yes. Both A/RHx-AN and A/RHx-CP series maintain identical sensor type, humidity range, output type, accuracy, response time, and supply voltage specifications. Series designation does not affect electrical or mechanical compatibility.

Q2: What is the difference between the operating temperature ranges of –40°C–60°C and 1.5°C–60°C?

A: Parts with –40°C–60°C operating range (A/RH5-CP-D and A/RH5-AN-D) are qualified for operation at lower temperatures. For applications operating only within 1.5°C–60°C, both temperature-rated variants are functionally equivalent.

Q3: Does Tape & Box (TB) packaging affect sensor performance?

A: No. Tape & Box packaging is a distribution and assembly format only. It does not alter the electrical characteristics, output signals, accuracy, or response time of the sensor module.

Q4: Are all substitute parts manufactured by the same company?

A: Yes. All parts listed are manufactured by Automation Components, Inc., ensuring consistent quality standards and specifications.

Q5: Which substitute part should be selected for maximum inventory availability?

A: A/RH5-AN-R2O currently maintains the highest inventory level at 1084 units, followed by A/RH5-AN-RSO-A03-A1 at 1076 units. Both parts meet all electrical and mechanical requirements of the primary part.

Q6: Can substitute parts be mixed in the same application or system?

A: Yes. All substitute parts deliver identical output signals (0V–5V, 0V–10V, 4mA–20mA), accuracy (±5% RH), and response time (20 s). They are electrically interchangeable within the same circuit or control system.

Q7: What determines whether a part qualifies as a substitute?

A: Substitution is based on matching core parameters: sensor type, humidity range, output type, output signals, accuracy, response time, supply voltage, and mounting type. Packaging format and operating temperature range variations are allowed differences that do not affect substitution eligibility.
