Key Parameters

Substitute Part Grouping Explanation

Substitution of the HPB100W2DA 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: 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 / Case: Module Cube
• Termination Style: Connector

The HPB200W2DA meets all mandatory matching parameters and qualifies as a direct substitute. This part maintains identical pressure measurement specifications, communication protocol, electrical supply requirements, and physical interface characteristics. The HPB200W2DA is currently in active product status, ensuring ongoing availability and support.

Engineering Selection Recommendations

The HPB200W2DA is the direct substitute for the obsolete HPB100W2DA. Both parts are manufactured by Honeywell Aerospace and maintain identical specifications across all critical functional and interface parameters. The HPB200W2DA offers improved accuracy (±0.006 PSI versus ±0.012 PSI), providing enhanced measurement precision while maintaining full compatibility with existing system designs.

The HPB200W2DA is currently in active product status, ensuring component availability and manufacturer support. Both parts carry identical regulatory classifications (EAR99, HTSUS 9026.20.4000) and moisture sensitivity ratings (MSL 1). The substitution requires no modifications to electrical connections, pneumatic interfaces, or communication protocols.

Frequently Asked Questions (FAQ)

Q: Can the HPB200W2DA directly replace the HPB100W2DA in existing installations?

A: Yes. The HPB200W2DA maintains identical pressure measurement range, RS-232 output protocol, electrical supply voltage, port size, port style, operating temperature range, and package configuration. No hardware or firmware modifications are required.

Q: What is the difference in accuracy between these two parts?

A: The HPB100W2DA has an accuracy specification of ±0.012 PSI (±0.08 kPa), while the HPB200W2DA has an accuracy specification of ±0.006 PSI (±0.04 kPa). The HPB200W2DA provides twice the measurement precision.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical regulatory classifications: EAR99 export control, HTSUS code 9026.20.4000, and RoHS non-compliant status. Both have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the physical interface compatibility between these parts?

A: Both parts feature identical pneumatic interfaces: Male 0.13" (3.18mm) barbed tube ports. Both use connector-based termination and are packaged in Module Cube form factor. Direct mechanical substitution is possible.

Q: Why is the HPB100W2DA classified as obsolete?

A: The HPB100W2DA has been discontinued by Honeywell Aerospace. The HPB200W2DA is the active equivalent part and should be used for all new designs and field replacements.

Q: Are there any electrical supply differences?

A: No. Both parts operate with identical voltage supply specifications: 5.5V to 30V. Existing power supply connections require no modification.
