Key Parameters

Substitute Part Grouping Explanation

Substitution of the HPA100R2DA is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Pressure Type: Absolute
• Operating Pressure: 17.6 PSI (121.35 kPa)
• Output Type: RS-232
• Voltage Supply Range: 5.5V ~ 30V
• Port Size: Male - 0.13" (3.18mm) Tube
• Port Style: Barbed
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: Module Cube
• Termination Style: Connector

Allowable Variation:

• Accuracy: May improve (lower tolerance value) without affecting functional compatibility
• Product Status: Active status preferred for ongoing availability

The HPA200R2DA meets all mandatory matching parameters and represents a direct substitute with improved accuracy specification.

Engineering Selection Recommendations

The HPA200R2DA is the direct substitute for the obsolete HPA100R2DA. Selection of the HPA200R2DA is supported by the following factors:

Product Status: The HPA200R2DA maintains active product status with Honeywell Aerospace, ensuring continued availability and supply chain reliability compared to the obsolete HPA100R2DA.

Regulatory Compliance: Both components share identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS code (9026.20.4000), indicating equivalent regulatory treatment in procurement and export contexts.

Performance Enhancement: The HPA200R2DA provides improved accuracy specification (±0.03% versus ±0.06%), representing a performance upgrade while maintaining full electrical and mechanical compatibility.

Interface Compatibility: All electrical interfaces (RS-232 output, 5.5V ~ 30V supply), mechanical interfaces (0.13" barbed male tube port), and package form factor (Module Cube connector termination) are identical, enabling direct substitution without system redesign.

Frequently Asked Questions (FAQ)

Q: Can the HPA200R2DA replace the HPA100R2DA in existing systems?

A: Yes. The HPA200R2DA is a direct substitute. All electrical parameters (supply voltage, output protocol, operating temperature range), mechanical interfaces (port size, barb style, connector termination), and pressure specifications (absolute type, 17.6 PSI operating point) are identical. The improved accuracy specification of the HPA200R2DA does not create incompatibility.

Q: What is the primary reason for substitution?

A: The HPA100R2DA is classified as obsolete. The HPA200R2DA provides equivalent functionality with active product status, ensuring long-term availability and supply chain continuity.

Q: Are there any compliance differences between these parts?

A: No. Both components share identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS code (9026.20.4000). Procurement and export compliance requirements remain unchanged.

Q: Will the improved accuracy of the HPA200R2DA affect system calibration?

A: The HPA200R2DA's improved accuracy (±0.03% versus ±0.06%) represents a performance enhancement. Systems designed for the HPA100R2DA's ±0.06% accuracy specification will operate within acceptable tolerance with the HPA200R2DA.

Q: Are the physical dimensions and connector types identical?

A: Yes. Both components use Module Cube packaging with connector termination style. The port interface is identical: Male 0.13" (3.18mm) barbed tube connection.

Q: What is the supply voltage compatibility?

A: Both components operate across the identical supply voltage range of 5.5V to 30V, ensuring direct compatibility with existing power distribution systems.
