Substitute Part Grouping Explanation

Substitution of the HPB100X2DA is determined by strict equivalence across the following critical parameters:

Pressure Measurement Specifications: Operating pressure range of 7.25 PSI to 17.4 PSI (50 kPa to 120 kPa) and absolute pressure type must be maintained.

Output Interface: RS-232 digital output type is required for system compatibility.

Electrical Requirements: Supply voltage range of 5.5 V to 30 V must be supported.

Mechanical Interface: Female 1/8" (3.18 mm) Swagelok™ threaded port configuration must be identical.

Environmental Specifications: Operating temperature range of -40°C to 85°C must be supported.

Physical Form Factor: Module Cube package type must be maintained.

Regulatory Compliance: ECCN EAR99 and HTSUS 9026.20.4000 classification must align.

The HPB200X2DA meets all these criteria and qualifies as a direct substitute. The HPB200X2DA is an active product with improved accuracy specification (±0.006 PSI versus ±0.012 PSI), ensuring enhanced performance while maintaining full electrical and mechanical compatibility.

Engineering Selection Recommendations

The HPB200X2DA is the direct substitute for the obsolete HPB100X2DA. Both components share identical electrical, mechanical, and environmental specifications. The HPB200X2DA is currently in active production status, ensuring long-term availability and supply chain continuity.

The HPB200X2DA provides improved measurement accuracy (±0.006 PSI compared to ±0.012 PSI), delivering enhanced precision without requiring any system modifications. Both parts maintain identical RoHS non-compliance status and regulatory classifications (ECCN EAR99, HTSUS 9026.20.4000), ensuring compliance consistency in applications where these designations are relevant.

For new designs or system upgrades, the HPB200X2DA is the appropriate selection. For legacy system maintenance requiring direct replacement of HPB100X2DA units, the HPB200X2DA provides full compatibility with performance improvement.

Frequently Asked Questions (FAQ)

Q: Can the HPB200X2DA directly replace the HPB100X2DA in existing systems?

A: Yes. The HPB200X2DA is a direct substitute. All electrical connections, mechanical interfaces, and environmental operating ranges are identical. No system modifications are required.

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

A: The HPB100X2DA has an accuracy specification of ±0.012 PSI (±0.08 kPa), while the HPB200X2DA has an accuracy specification of ±0.006 PSI (±0.04 kPa). The HPB200X2DA provides twice the measurement precision.

Q: Are the port connections identical?

A: Yes. Both the HPB100X2DA and HPB200X2DA feature Female 1/8" (3.18 mm) Swagelok™ threaded ports. No adapter or modification is necessary.

Q: What is the supply voltage requirement?

A: Both parts operate with a supply voltage range of 5.5 V to 30 V. Existing power supply configurations will function without adjustment.
