Engineering Selection Recommendations

All substitute parts listed are qualified for direct replacement of the A/RH5-CSI-RO based on electrical and mechanical parameter equivalence. Selection among substitute options is determined by application-specific requirements:

For Standard Operating Temperature Range (1.5°C to 60°C): Select from A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, A/RH5-CP-R, or A/RH5-CP-R2. These parts maintain identical operating temperature specifications to the A/RH5-CSI-RO and are available in Tape & Box packaging with inventory levels ranging from 750 to 1084 units.

For Extended Low-Temperature Operation (-40°C to 60°C): Select A/RH5-AN-D or A/RH5-CP-D. These parts extend the lower operating temperature limit to -40°C, supporting applications requiring cold environment performance. Both are available in Tape & Box packaging with 800 and 801 units in stock respectively.

For Series-Specific Requirements: A/RHx-AN series parts (A/RH5-AN-R, A/RH5-AN-R2, A/RH5-AN-R2O, A/RH5-AN-RSO-A03-A1) and A/RHx-CP series parts (A/RH5-CP-R, A/RH5-CP-R2) are available as alternatives to the A/RHx-CSI series. All maintain identical functional specifications and active product status.

All substitute parts are new original components in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q1: Can A/RH5-AN-D or A/RH5-CP-D be used as direct replacements for A/RH5-CSI-RO in standard temperature environments?

A: Yes. A/RH5-AN-D and A/RH5-CP-D are electrically and mechanically equivalent to A/RH5-CSI-RO. The extended operating temperature range (-40°C to 60°C) does not prevent operation in standard temperature environments (1.5°C to 60°C). These parts are suitable for applications where extended cold-temperature capability is not required but may be preferred for inventory consolidation or supply availability.

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

A: Series designations reflect internal product line classifications within Automation Components, Inc. All three series (CSI, AN, CP) deliver identical electrical performance: 0–100% RH measurement range, ±5% RH accuracy, 20-second response time, and dual analog output capability. Series differences do not affect functional substitution eligibility.

Q3: Are Tape & Box packaged parts (A/RH5-AN-R, A/RH5-CP-R2, etc.) compatible with applications designed for the standard module packaging of A/RH5-CSI-RO?

A: Yes. Tape & Box packaging is a distribution and storage format that does not affect the module's electrical or mechanical interface. The sensor module itself maintains identical chassis-mount configuration and connector specifications across all packaging formats. Tape & Box packaging is suitable for high-volume procurement and automated assembly environments.

Q4: Which substitute part offers the highest current inventory availability?

A: A/RH5-AN-R2O provides the highest inventory level with 1084 units in stock, followed by A/RH5-AN-RSO-A03-A1 with 1076 units. Both parts maintain identical specifications to A/RH5-CSI-RO within the standard operating temperature range (1.5°C to 60°C).

Q5: Can substitute parts be mixed within a single system or application?

A: Yes. All substitute parts are electrically and mechanically equivalent, delivering identical output signals (0V–5V, 0V–10V, 4mA–20mA) and operating parameters. Multiple substitute parts can be deployed in parallel or distributed applications without functional impact, provided the application does not require temperature operation below 1.5°C (in which case A/RH5-AN-D or A/RH5-CP-D must be selected).

Q6: What supply voltage compatibility should be verified during substitution?

A: All listed substitute parts support identical dual supply voltage specifications: 18–28VAC or 12–40VDC. No voltage compatibility verification is required when substituting any listed part for A/RH5-CSI-RO.

Q7: Is response time identical across all substitute parts?

A: Yes. All substitute parts maintain a 20-second response time specification, identical to A/RH5-CSI-RO. Response time is a core functional parameter that does not vary across the substitute parts list.
