Identical Compliance Profile: Both components share identical RoHS non-compliance status and ECCN/HTSUS classifications, maintaining regulatory consistency in applications where legacy compliance requirements apply.
Connector-Based Termination: The filtered connector port configuration ensures mechanical and electrical compatibility with existing interface infrastructure designed for the HPA100F2DA.

Frequently Asked Questions (FAQ)

Q: Can the HPA200F2DA directly replace the HPA100F2DA in existing installations?

A: Yes. The HPA200F2DA maintains identical electrical interface specifications (RS-232 output, 5.5V to 30V supply), mechanical packaging (Module Cube), and operational environmental ratings (-40°C to 85°C). No circuit modifications or mechanical redesign is required for substitution.

Q: What is the primary advantage of selecting the HPA200F2DA over the HPA100F2DA?

A: The HPA200F2DA is an active product with current manufacturing support from Honeywell Aerospace, whereas the HPA100F2DA is obsolete. Additionally, the substitute component provides improved measurement accuracy (±0.03% versus ±0.06%).

Q: Are the pressure ratings identical between these components?

A: Yes. Both components are rated for 17.6 PSI (121.35 kPa) absolute pressure operation, with identical filtered port configuration and connector termination style.

Q: Do these components share the same supply voltage requirements?

A: Yes. Both the HPA100F2DA and HPA200F2DA operate across the identical 5.5V to 30V supply voltage range, ensuring compatibility with existing power distribution systems.

Q: What is the significance of the filtered port configuration?

A: The filtered port style provides integrated pressure signal conditioning, protecting the sensor from particulate contamination and pressure transients. This specification is identical across both components.

Q: Are there any compliance differences between the main part and substitute?

A: No. Both components share identical RoHS non-compliance status and are classified under the same ECCN (EAR99) and HTSUS (9026.20.4000) codes, maintaining regulatory consistency.

Q: What is the moisture sensitivity level for these barometer sensors?

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
