HPA100W2DA Equivalent & Substitute Parts

Part Overview

The HPA100W2DA is an absolute pressure barometer sensor manufactured by Honeywell Aerospace, designed for industrial automation applications. This component features RS-232 digital output and operates across a wide temperature range of -40°C to 85°C. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs. The HPA100W2DA remains available in inventory (1076 units), but obsolescence status requires engineers to evaluate active substitute options for long-term component sourcing strategy.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HPA100W2DA 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
• Termination Style: Connector
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: Module Cube
• ECCN Classification: EAR99
• HTSUS Code: 9026.20.4000

Allowable Variation:

• Accuracy: May improve (lower tolerance value) without affecting substitution validity
• Product Status: Active status preferred for new designs and long-term availability
• Inventory Availability: Secondary consideration; does not affect electrical or mechanical compatibility

The HPA200W2DA meets all mandatory matching parameters and represents a direct substitute with improved accuracy specification (±0.03% versus ±0.06%).

Parameter Comparison

Engineering Selection Recommendations

For Obsolescence Mitigation: The HPA200W2DA is the direct substitute for HPA100W2DA applications. Both components share identical electrical interfaces, mechanical form factors, and operational specifications. The HPA200W2DA carries active product status, ensuring continued manufacturer support and supply chain availability.

For New Designs: The HPA200W2DA is the appropriate selection for new industrial automation pressure sensing applications requiring absolute pressure measurement at 17.6 PSI with RS-232 output. The improved accuracy specification (±0.03%) provides enhanced measurement precision without requiring design modifications.

Compliance Considerations: Both parts maintain identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS coding (9026.20.4000). No compliance-related design changes are required when transitioning from HPA100W2DA to HPA200W2DA.

Inventory Strategy: Existing HPA100W2DA inventory (1076 units) may continue to be deployed in current production. The HPA200W2DA (1135 units available) should be specified for new production orders and future system designs to ensure long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can HPA200W2DA directly replace HPA100W2DA in existing assemblies?

A: Yes. The HPA200W2DA is a direct substitute. Both components feature identical port sizes (Male - 0.13" barbed tube), connector termination styles, supply voltage ranges (5.5V ~ 30V), and RS-232 output protocols. No mechanical or electrical modifications to the host system are required.

Q: What is the significance of the accuracy difference between ±0.06% and ±0.03%?

A: The HPA200W2DA provides improved measurement accuracy. This represents a tighter tolerance specification and does not affect compatibility. Systems designed for ±0.06% accuracy will operate within specification with the HPA200W2DA.

Q: Are there any temperature or pressure operating range differences?

A: No. Both components operate identically across the temperature range of -40°C to 85°C and are rated for 17.6 PSI (121.35 kPa) absolute pressure measurement.

Q: Why is HPA100W2DA classified as obsolete?

A: Obsolescence status indicates the manufacturer has discontinued active production. The HPA200W2DA represents the current active product line for this sensor category, ensuring ongoing support and supply availability.

Q: Are connector types and port configurations identical?

A: Yes. Both parts use male barbed tube ports (0.13" / 3.18mm) with connector termination styles. Tubing and connector compatibility is maintained between the two models.

Q: What is the inventory status for each part?

A: HPA100W2DA has 1076 units in stock (obsolete status). HPA200W2DA has 1135 units in stock (active status). For long-term sourcing, the HPA200W2DA is the recommended selection.

Q: Do both parts share the same export classification?

A: Yes. Both components are classified under ECCN EAR99 and HTSUS code 9026.20.4000, maintaining identical export and regulatory compliance requirements.
