Key Parameters

Substitute Part Grouping Explanation

Substitution of the HPB100XTTA is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Pressure Type: Absolute
• Operating Pressure Range: 7.25 PSI ~ 17.4 PSI (50 kPa ~ 120 kPa)
• Output Type: TTL
• Supply Voltage Range: 6V ~ 26V
• Port Size: Female - 1/8" (3.18 mm) Swagelok™
• Port Style: Threaded
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: Module Cube
• Termination Style: Connector

Allowable Variation Parameters:

• Accuracy: May improve (lower tolerance value) without affecting substitution validity
• Product Status: Active status preferred for ongoing availability
• Manufacturer: Honeywell Aerospace (same manufacturer maintains design consistency)

The HPB200XTTA qualifies as a direct substitute based on full alignment with all mandatory parameters and improved accuracy specification.

Engineering Selection Recommendations

The HPB200XTTA is the direct equivalent substitute for the HPB100XTTA. Selection criteria are based on the following engineering factors:

Product Status Consideration: The HPB100XTTA is classified as obsolete, creating supply chain risk for new procurement and long-term system support. The HPB200XTTA maintains active product status with Honeywell Aerospace, ensuring continued availability and manufacturing support.

Functional Equivalence: Both components share identical specifications across all critical operating parameters: pressure measurement range, output signal type, supply voltage compatibility, mechanical interface dimensions, and environmental operating limits. This equivalence ensures direct functional replacement without circuit redesign or system reconfiguration.

Performance Enhancement: The HPB200XTTA provides improved accuracy of ±0.006 PSI compared to the HPB100XTTA's ±0.012 PSI specification. This represents a 50% reduction in measurement uncertainty, which enhances system performance without introducing any compatibility concerns.

Compliance Alignment: Both components maintain identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS coding (9026.20.4000), ensuring regulatory and export control consistency.

Mechanical and Electrical Interface: Port configuration, connector type, and termination style are identical between both components, enabling direct physical and electrical substitution without adapter requirements or interface modifications.

Frequently Asked Questions (FAQ)

Q: Can the HPB200XTTA directly replace the HPB100XTTA in existing applications?
