Engineering Selection Recommendations

The HPA200RTTA is a direct functional equivalent to the HPA100RTTA for industrial automation applications requiring absolute pressure measurement at 17.6 PSI (121.35 kPa) with TTL output.

Primary Selection Advantage: The HPA200RTTA maintains active product status with Honeywell Aerospace, ensuring continued availability and supply chain reliability. The obsolete classification of the HPA100RTTA creates long-term sourcing constraints.

Specification Alignment: Both components share identical electrical supply requirements (6V ~ 26V), mechanical port configuration (male barbed 0.13" tube), and environmental operating parameters (-40°C ~ 85°C). The HPA200RTTA provides improved accuracy at ±0.03% compared to the HPA100RTTA at ±0.06%, representing enhanced measurement precision within the same application envelope.

Regulatory Compliance: Both parts maintain identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring equivalent export control and tariff treatment. Both are RoHS non-compliant with MSL rating of 1 (Unlimited).

Connector and Package Compatibility: Identical Module Cube packaging and connector termination style ensure mechanical interchangeability in existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the HPA200RTTA directly replace the HPA100RTTA in existing systems?

A: Yes. The HPA200RTTA is electrically and mechanically compatible with the HPA100RTTA.
