• Operating Pressure: 17.6 PSI (121.35 kPa)
• Output Type: TTL
• Voltage Supply Range: 6V ~ 26V
• Port Size: Female - 1/8" (3.18mm) Swagelok™
• Port Style: Threaded
• Termination Style: Connector
• Operating Temperature: -40°C ~ 85°C
• Package / Case: Module Cube
• MSL: 1 (Unlimited)

The HPA200XTTA qualifies as a direct substitute based on complete alignment with all critical electrical, mechanical, and environmental parameters. The primary distinction is improved accuracy specification and active product status.

Parameter Comparison

Engineering Selection Recommendations

The HPA200XTTA is a direct functional equivalent to the HPA100XTTA for applications requiring absolute pressure measurement at 17.6 PSI with TTL output in the -40°C to 85°C operating range. Both components share identical electrical interfaces, mechanical port configurations, and environmental specifications.

The HPA200XTTA offers improved accuracy (±0.03% versus ±0.06%) and maintains active product status with Honeywell Aerospace, ensuring continued availability and technical support. Both components are RoHS non-compliant and carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications.

Selection between these parts should be based on application accuracy requirements and supply chain considerations. The obsolete status of the HPA100XTTA makes the HPA200XTTA the preferred choice for new designs and ongoing procurement.

Frequently Asked Questions (FAQ)
