Engineering Selection Recommendations

All substitute parts listed are active products from Automation Components, Inc. with identical core electrical and mechanical specifications. Selection between the A/RH5-CSI-O and its substitutes should be based on:

Inventory Availability: A/RH5-R2 offers the highest stock level at 1124 units. A/RH5-D has the lowest inventory at 661 units.

Operating Temperature Envelope: The A/RH5-CSI-O, A/RH5-AN-O, and A/RH5-CP-O operate across -40°C ~ 60°C. The A/RH5-O, A/RH5-R, and A/RH5-R2 operate across 1.5°C ~ 60°C. For applications requiring operation below 1.5°C, the A/RH5-CSI-O, A/RH5-AN-O, or A/RH5-CP-O are required.

Packaging Format: The A/RH5-CSI-O is supplied in standard module packaging. All substitute parts are available in Tape & Box (TB) format, which may affect procurement logistics and handling procedures.

All parts maintain identical humidity measurement range, output signal types, accuracy, response time, and supply voltage specifications, ensuring direct functional compatibility within specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can A/RH5-R2 directly replace A/RH5-CSI-O in all applications?

A: A/RH5-R2 is a parametric equivalent for humidity measurement performance. However, the operating temperature range differs: A/RH5-R2 operates from 1.5°C ~ 60°C while A/RH5-CSI-O operates from -40°C ~ 60°C. Direct replacement is valid only for applications operating above 1.5°C.

Q: What is the difference between the substitute parts?

A: All substitute parts provide identical humidity sensing performance with 0 ~ 100% RH range, ±5% accuracy, and 20 s response time. Differences exist in operating temperature range and packaging format. A/RH5-CSI-O, A/RH5-AN-O, and A/RH5-CP-O support extended low-temperature operation to -40°C. All others operate from 1.5°C minimum.

Q: Are packaging differences significant for substitution?

A: The A/RH5-CSI-O uses standard module packaging. Substitute parts use Tape & Box (TB) format. This affects receiving, storage, and handling procedures but does not impact electrical or mechanical performance. Verify procurement and inventory management compatibility before selection.

Q: Which substitute part has the best availability?

A: A/RH5-R2 has the highest inventory at 1124 units in stock. A/RH5-D has the lowest at 661 units. Inventory levels should be confirmed at time of procurement.

Q: Can I use A/RH5-O as a substitute in a -30°C environment?

A: No. A/RH5-O operates from 1.5°C minimum. For -30°C operation, use A/RH5-CSI-O, A/RH5-AN-O, or A/RH5-CP-O, which are rated to -40°C.

Q: Do all substitute parts support the same output signal options?

A: Yes. All parts provide identical output capability: 0V ~ 5V, 0V ~ 10V, and 4mA ~ 20mA analog signals with ±5% RH accuracy.
