Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A/RH5-AN-RO are identified based on strict electrical and mechanical parameter equivalence. All substitute candidates share the following critical parameters with the main part:

Core Equivalence Criteria:

• Sensor Type: Humidity, Temperature
• 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
• Voltage Supply: 18 ~ 28VAC, 12 ~ 40VDC
• Mounting Type: Chassis Mount
• Package / Case: Module
• Product Status: Active

Substitution Groups:

Group 1: A/RHx-AN Series (Analog Voltage/Current Output, Standard Temperature Range) Parts A/RH5-AN-D, A/RH5-AN-R, A/RH5-AN-R2, and A/RH5-AN-R2O maintain identical electrical specifications and operating temperature range (1.5°C ~ 60°C) as the main part. These differ only in packaging configuration and internal connector designations. All are supplied in Tape & Box (TB) packaging.

Group 2: Extended Temperature Range Variants Parts A/RH5-AN-D and A/RH5-CP-D extend the operating temperature range to –40°C ~ 60°C, providing cold-environment capability beyond the standard 1.5°C ~ 60°C range. These are suitable for applications requiring sub-zero operation.

Group 3: A/RHx-CP Series (Connector Panel Mount Variants) Parts A/RH5-CP-R and A/RH5-CP-R2 belong to the CP series designation, indicating connector panel mounting configuration. These maintain all electrical parameters and standard operating temperature (1.5°C ~ 60°C) but differ in mechanical mounting interface from the AN series.

Group 4: Specialized Configuration Part A/RH5-AN-RSO-A03-A1 represents a fully specified variant with integrated connector and calibration designation (A03-A1). All electrical and thermal parameters remain equivalent to the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (No Thermal Compromise): Parts A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, A/RH5-CP-R, and A/RH5-CP-R2 are direct functional equivalents to the A/RH5-AN-RO. All maintain identical humidity measurement range, output signal types, accuracy, response time, and supply voltage specifications. These parts are suitable for direct substitution in applications operating within the 1.5°C to 60°C temperature envelope. Selection among these variants depends on connector type (AN series versus CP series) and internal configuration designation (R, R2, R2O).

Extended Temperature Capability: Parts A/RH5-AN-D and A/RH5-CP-D extend the lower operating temperature limit to –40°C, enabling deployment in cold-storage, outdoor, and arctic environments. These variants are electrically and functionally identical to the main part but provide enhanced thermal performance. Use these variants when application requirements specify sub-zero operation.

Specialized Configuration: Part A/RH5-AN-RSO-A03-A1 includes integrated connector and calibration designation. This variant maintains full electrical equivalence and is suitable for applications requiring pre-configured connector interfaces and documented calibration traceability.

Packaging Considerations: The main part A/RH5-AN-RO is supplied in Module packaging. All substitute parts are available in Tape & Box (TB) packaging, which is standard for component distribution and automated assembly processes. Verify packaging compatibility with procurement and assembly workflows before selection.

Inventory Availability: All substitute parts maintain active product status with substantial stock levels (750–1084 units). Part A/RH5-AN-R2O offers the highest inventory availability (1084 units), followed by A/RH5-AN-RSO-A03-A1 (1076 units), supporting high-volume procurement and supply chain continuity.

Frequently Asked Questions (FAQ)

Q1: Can A/RH5-AN-R, A/RH5-AN-R2, and A/RH5-AN-R2O be used interchangeably with A/RH5-AN-RO?

A: Yes. These parts share identical electrical specifications, humidity measurement range (0–100% RH), output signal types (0V–5V, 0V–10V, 4mA–20mA), accuracy (±5% RH), response time (20 s), supply voltage (18–28VAC, 12–40VDC), and operating temperature range (1.5°C–60°C). Differences in part number suffixes (R, R2, R2O) indicate internal connector or configuration variants, not functional differences. Substitution is valid for applications within the specified temperature range.

Q2: What is the difference between A/RHx-AN and A/RHx-CP series?

A: The AN and CP designations indicate different mechanical mounting interfaces. AN series uses standard chassis mounting, while CP series uses connector panel mounting. Both series maintain identical electrical specifications and humidity measurement performance. Selection depends on the mechanical mounting requirement of the application. Verify the mounting interface compatibility before substitution.

Q3: When should I use A/RH5-AN-D or A/RH5-CP-D instead of the standard variants?

A: Use the D-suffix variants (A/RH5-AN-D or A/RH5-CP-D) when the application requires operation below 1.5°C. These parts extend the lower operating temperature limit to –40°C, enabling deployment in cold environments. All other electrical and performance parameters remain identical to standard variants. If your application operates only within 1.5°C to 60°C, standard variants are sufficient.

Q4: Are there any compatibility issues when substituting between AN and CP series?

A: Electrical compatibility is complete; both series deliver identical humidity and temperature measurement performance. However, mechanical compatibility depends on the mounting interface design of your application. AN series requires standard chassis mounting provisions, while CP series requires connector panel mounting provisions. Verify the mechanical mounting interface before substitution to avoid installation conflicts.

Q5: What does the RSO-A03-A1 designation in A/RH5-AN-RSO-A03-A1 indicate?

A: The RSO-A03-A1 suffix indicates a specialized configuration with integrated connector (RSO) and calibration designation (A03-A1). This variant maintains full electrical equivalence to the main part and is suitable for applications requiring pre-configured connector interfaces and documented calibration traceability. Electrical performance and humidity measurement specifications are identical to standard AN series variants.

Q6: Does packaging type (Module versus Tape & Box) affect electrical performance?

A: No. Packaging type affects only procurement, storage, and assembly processes. Module packaging and Tape & Box (TB) packaging contain identical components with identical electrical specifications. Selection should be based on compatibility with your procurement and automated assembly workflows, not on electrical performance.

Q7: Can I substitute A/RH5-AN-RO with any of the listed alternatives without design changes?

A: Yes, for applications operating within 1.5°C to 60°C. All listed alternatives maintain identical humidity measurement range, output signal types, accuracy, response time, and supply voltage specifications. Verify only the mechanical mounting interface (AN versus CP series) matches your application design. If your application requires operation below 1.5°C, use D-suffix variants (A/RH5-AN-D or A/RH5-CP-D).

Q8: Which substitute part offers the best inventory availability?

A: Part A/RH5-AN-R2O offers the highest current inventory with 1084 units in stock, followed by A/RH5-AN-RSO-A03-A1 with 1076 units. Both parts maintain identical electrical specifications to the main part and are suitable for high-volume procurement and supply chain continuity planning.
