Key Parameters

Substitute Part Grouping Explanation

Substitution of the HPB100RTTA is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure range must match 7.25PSI ~ 17.4PSI (50kPa ~ 120kPa) with absolute pressure type classification.

Electrical Interface: Output type must be TTL. Voltage supply range must encompass 6V ~ 26V operation.

Mechanical Interface: Port size must be Male - 0.13" (3.18mm) Tube with barbed port style. Termination must be connector-based.

Environmental Compliance: Operating temperature range must support -40°C ~ 85°C. Moisture sensitivity level must be 1 (Unlimited).

Physical Form Factor: Package must be Module Cube configuration.

The HPB200RTTA meets all substitution criteria while offering improved accuracy specification (±0.006PSI versus ±0.012PSI) and active product status, making it a direct functional equivalent.
