A/RH5-AN-D-NIST Humidity and Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The A/RH5-AN-D-NIST is an active humidity and temperature sensor manufactured by Automation Components, Inc., designed for chassis mount applications requiring analog current and voltage outputs. This sensor measures relative humidity across the full 0 to 100% RH range with ±5% RH accuracy and includes integrated temperature measurement capability. The product is currently in active status with 899 pieces in new original stock inventory.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when operational temperature range requirements differ from the standard specification.

Secondary Variation Parameters:

Operating Temperature Range: Substitutes may operate at 1.5°C ~ 60°C (narrower low-temperature limit) or -40°C ~ 60°C (full range)

All substitute parts listed maintain full parametric equivalence across humidity measurement, output characteristics, accuracy, response time, and supply voltage specifications. Differences in operating temperature range and connector type (suffix designations) represent the only allowed variations.

Engineering Selection Recommendations

Full Temperature Range Substitutes (-40°C ~ 60°C):

The A/RH5-AN-D and A/RH5-CP-D maintain identical operating temperature specifications to the A/RH5-AN-D-NIST. These parts are direct substitutes for applications requiring operation across the full extended low-temperature range. Both parts are in active product status with confirmed inventory availability.

Restricted Temperature Range Substitutes (1.5°C ~ 60°C):

The 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 where the minimum operating temperature requirement does not extend below 1.5°C. All are active product status with higher inventory levels than the primary part number. These substitutes are appropriate for indoor environmental monitoring, HVAC systems, and controlled facility applications where sub-zero operation is not required.

Connector Type Variations:

The A/RH5-AN series (suffix -AN-) and A/RH5-CP series (suffix -CP-) represent different connector interface types. Selection between these series depends on the specific connector requirements of the target application. Both series maintain identical sensor performance and output characteristics.

All substitute parts are manufactured by Automation Components, Inc., and are supplied in Tape & Box (TB) packaging format suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can A/RH5-AN-R2 be used as a direct replacement for A/RH5-AN-D-NIST?

A: The A/RH5-AN-R2 is parametrically equivalent across all humidity measurement, output, accuracy, and supply voltage specifications. The difference is the operating temperature range: A/RH5-AN-R2 operates from 1.5°C to 60°C, while A/RH5-AN-D-NIST operates from -40°C to 60°C. Use A/RH5-AN-R2 only if your application does not require operation below 1.5°C.

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

A: Both parts maintain identical humidity measurement range, output types, accuracy, response time, and operating temperature specifications. The difference is the connector type designated by the suffix: -AN- versus -CP-. Select based on the connector interface required by your application circuit.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts listed are supplied in Tape & Box (TB) packaging format. The primary part A/RH5-AN-D-NIST is also supplied in this format, ensuring compatibility with automated assembly equipment.

Q: Which substitute part has the highest inventory availability?

A: The A/RH5-AN-R2O has the highest inventory with 1084 pieces in stock, followed by A/RH5-AN-RSO-A03-A1 with 1076 pieces. Both maintain the 1.5°C to 60°C operating temperature range.

Q: Can I use A/RH5-CP-R2 in place of A/RH5-AN-D-NIST?

A: The A/RH5-CP-R2 is parametrically equivalent for humidity measurement, output characteristics, accuracy, and supply voltage. However, it uses the CP-series connector type instead of the AN-series connector, and operates from 1.5°C to 60°C instead of -40°C to 60°C. Use only if both the connector type and temperature range are compatible with your application.

Q: What parameters remain constant across all substitute parts?

A: All substitute parts maintain constant specifications for humidity range (0 ~ 100% RH), output type (Analog Current, Analog Voltage), output signals (0V ~ 5V, 0V ~ 10V, 4mA ~ 20mA), accuracy (±5% RH), response time (20 s), supply voltage (18 ~ 28VAC, 12 ~ 40VDC), mounting type (Chassis Mount), and package type (Module).
