A/RH5-O-BB Humidity Sensor Module - Equivalent & Substitute Parts

Part Overview

The A/RH5-O-BB is an active humidity sensor module manufactured by Automation Components, Inc., designed for analog output applications requiring relative humidity measurement across the full 0 to 100% RH range. This chassis-mounted module provides dual analog output options (voltage and current) with ±5% RH accuracy and a 20-second response time. The part is currently in active product status with 1005 units in stock.

Substitute parts are identified when design requirements necessitate alternative packaging configurations, extended operating temperature ranges, or inventory optimization while maintaining identical core sensor functionality and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A/RH5-O-BB is determined by equivalence across the following critical parameters:

Core Functional Parameters (Must Match):

• Humidity measurement range: 0 ~ 100% RH
• Output type: Analog Current and Analog Voltage
• Output levels: 0V ~ 5V, 0V ~ 10V, 4mA ~ 20mA
• Accuracy: ±5% RH
• Response time: 20 seconds
• Supply voltage: 18 ~ 28VAC, 12 ~ 40VDC
• Mounting type: Chassis Mount
• Package type: Module

Variable Parameters (Allowed to Differ):

• Operating temperature range
• Packaging format (Module vs. Tape & Box)
• Supplier device package designation

All identified substitute parts maintain identical sensor functionality and electrical output specifications. Differences exist only in packaging configuration and operating temperature ratings, which do not affect core humidity measurement capability.

Parameter Comparison

Engineering Selection Recommendations

Standard Operating Environment (1.5°C ~ 60°C):

For applications operating within the standard temperature range of 1.5°C to 60°C, the following parts are functionally equivalent to the A/RH5-O-BB:

• A/RH5-O: Identical operating temperature range with Tape & Box packaging. Inventory: 1032 units.
• A/RH5-R: Identical operating temperature range with Tape & Box packaging. Inventory: 1036 units.
• A/RH5-R2: Identical operating temperature range with Tape & Box packaging. Inventory: 1124 units.

Extended Temperature Environment (-40°C ~ 60°C):

For applications requiring operation at temperatures below 1.5°C or down to -40°C, the following parts provide extended low-temperature capability:

• A/RH5-AN-O: Extended operating range with Tape & Box packaging. Inventory: 1067 units.
• A/RH5-CP-O: Extended operating range with Tape & Box packaging. Inventory: 1015 units.
• A/RH5-D: Extended operating range with Tape & Box packaging. Inventory: 661 units.

All substitute parts maintain active product status and are manufactured by Automation Components, Inc. Selection between equivalent parts should be based on packaging requirements and operating temperature specifications for the target application.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the A/RH5-O-BB?

A: A substitute part must maintain identical humidity measurement range (0 ~ 100% RH), output type (Analog Current and Analog Voltage), accuracy (±5% RH), response time (20 seconds), and supply voltage specifications (18 ~ 28VAC, 12 ~ 40VDC). Differences in packaging format and operating temperature range do not affect substitution eligibility.

Q: Can I use A/RH5-AN-O or A/RH5-CP-O in place of A/RH5-O-BB in a standard temperature environment?

A: Yes. Both A/RH5-AN-O and A/RH5-CP-O are functionally equivalent to A/RH5-O-BB for applications operating between 1.5°C and 60°C. These parts provide extended low-temperature capability (-40°C) but are fully compatible with standard temperature applications.

Q: What is the difference between the A/RH5-O-BB and A/RH5-O?

A: The primary difference is packaging format. A/RH5-O-BB is supplied in Module packaging, while A/RH5-O is supplied in Tape & Box (TB) packaging. All electrical and functional specifications are identical.

Q: Which substitute part has the highest inventory availability?

A: A/RH5-R2 has the highest inventory with 1124 units in stock, followed by A/RH5-AN-O with 1067 units.

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

A: Yes. All substitute parts listed are manufactured by Automation Components, Inc., the same manufacturer as the A/RH5-O-BB.

Q: Can I use a substitute part with an extended temperature range in a standard temperature application?

A: Yes. Parts rated for extended temperature ranges (-40°C ~ 60°C) are fully compatible with standard temperature applications (1.5°C ~ 60°C). Extended temperature capability does not restrict use in narrower temperature ranges.

Q: What should I consider when selecting between substitute parts with identical specifications?

A: Selection criteria should include: (1) packaging format requirements for your assembly process, (2) operating temperature range of your application, and (3) inventory availability for production scheduling.
