A/RH5-20K-D-BB Humidity and Temperature Sensor: Equivalent and Substitute Parts

Part Overview

The A/RH5-20K-D-BB 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. The sensor operates across a wide supply voltage range (18–28VAC, 12–40VDC) and temperature range (−40°C to 60°C), making it suitable for industrial environmental monitoring applications. With 807 units in current stock and active product status, substitute parts are identified to support procurement flexibility, inventory management, and application-specific packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A/RH5-20K-D-BB are identified based on strict parametric equivalence across the following critical criteria:

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
• Accuracy: ±5% RH
• Response time: 20 s
• Supply voltage: 18 ~ 28VAC, 12 ~ 40VDC
• Sensor type: Humidity, Temperature

Mechanical Parameters (Must Match):

• Mounting type: Chassis Mount
• Package / Case: Module

Allowed Variation:

• Operating temperature range: The main part operates −40°C to 60°C. Substitute parts with operating range 1.5°C to 60°C are acceptable as they cover the upper operational envelope; however, they do not extend to the lower −40°C limit.
• Packaging format: Tape & Box (TB) packaging is acceptable for substitution in applications where the original packaging format is not a constraint.

All seven substitute parts listed below meet the core electrical and mechanical parameters. Differences in operating temperature lower limit and packaging format are noted in the comparison table.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with Automation Components, Inc. and are in current stock inventory. Selection among the substitute parts should be based on the following engineering criteria:

Operating Temperature Requirement:

• If the application requires operation at temperatures below 1.5°C, only A/RH5-AN-D and A/RH5-CP-D are suitable, as they maintain the full −40°C to 60°C operating range of the original A/RH5-20K-D-BB.
• If the application operates only within the 1.5°C to 60°C range, all seven substitute parts are functionally equivalent.

Packaging Format:

• A/RH5-AN-D and A/RH5-CP-D are supplied in Tape & Box (TB) packaging, which differs from the original module packaging. Verify that TB packaging is compatible with procurement, storage, and assembly workflows.
• All other substitutes are also supplied in Tape & Box (TB) format.

Inventory Availability:

• A/RH5-AN-R2O (1084 units) and A/RH5-AN-RSO-A03-A1 (1076 units) offer the highest inventory levels for applications requiring extended lead-time protection.
• A/RH5-AN-R (750 units) and A/RH5-CP-R (768 units) offer the lowest inventory levels.

Series Designation:

• Parts designated A/RHx-AN series (A/RH5-AN-D, A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, A/RH5-AN-RSO-A03-A1) and A/RHx-CP series (A/RH5-CP-D, A/RH5-CP-R, A/RH5-CP-R2) represent different product lines within the A/RH5 humidity sensor family. Selection between series should be based on application-specific requirements not detailed in the parametric data.

Frequently Asked Questions (FAQ)

Q1: Can A/RH5-AN-R be used as a direct replacement for A/RH5-20K-D-BB in all applications?

A: A/RH5-AN-R is parametrically equivalent for humidity measurement, output signals, accuracy, and supply voltage. However, its operating temperature range (1.5°C to 60°C) does not extend to the −40°C lower limit of the original part. Use A/RH5-AN-R only in applications where the minimum operating temperature is 1.5°C or higher.

Q2: What is the difference between A/RH5-AN-D and A/RH5-CP-D?

A: Both parts maintain the full −40°C to 60°C operating temperature range and are supplied in Tape & Box (TB) packaging. The primary difference is their series designation (AN versus CP). All other electrical and mechanical parameters are identical. Selection between these parts should be based on application-specific requirements or design specifications that reference a particular series.

Q3: Why do some substitute parts have a lower operating temperature limit of 1.5°C instead of −40°C?

A: The substitute parts 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 specified with a 1.5°C lower operating limit. This represents a design or manufacturing variation within the A/RH5 product family. These parts are suitable for applications operating within the 1.5°C to 60°C range but are not suitable for applications requiring operation below 1.5°C.

Q4: Is Tape & Box (TB) packaging compatible with my assembly process?

A: Tape & Box (TB) packaging is a standard format for component distribution and is compatible with automated pick-and-place assembly equipment. However, if your procurement or assembly workflow requires a specific packaging format, verify compatibility with your supplier or assembly partner before substitution.

Q5: Which substitute part offers the best inventory availability?

A: A/RH5-AN-R2O has the highest inventory level at 1084 units, followed by A/RH5-AN-RSO-A03-A1 at 1076 units. Both parts are parametrically equivalent to the original A/RH5-20K-D-BB for applications operating within the 1.5°C to 60°C temperature range.

Q6: Are all substitute parts manufactured by Automation Components, Inc.?

A: Yes. All substitute parts listed are manufactured by Automation Components, Inc. and maintain active product status.

Q7: Can I mix substitute parts from different series (AN versus CP) in the same application?

A: All substitute parts meet the same electrical and mechanical specifications for humidity measurement, output signals, accuracy, response time, and supply voltage. Mixing parts from different series is permissible from a parametric standpoint. However, verify that your application design or procurement specifications do not mandate a single series designation.
