HPA100X2DA Barometer Equivalent & Substitute Parts

Part Overview

The HPA100X2DA is an absolute pressure barometer sensor manufactured by Honeywell Aerospace, designed for industrial automation applications. This sensor outputs pressure data via RS-232 interface with an operating pressure range of 17.6 PSI (121.35 kPa) and operates across a temperature range of -40°C to 85°C.

The HPA100X2DA carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure continued system functionality, maintain supply chain reliability, and support long-term industrial automation deployments where this sensor is integrated.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HPA100X2DA is determined by 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: Female - 1/8" (3.18mm) Swagelok™
• Port Style: Threaded
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: Module Cube
• Termination Style: Connector

Flexible Parameters (Allowable Variation):

• Accuracy: May improve (lower tolerance values acceptable)
• Product Status: Active status preferred for obsolete parts
• Manufacturer: Honeywell Aerospace (same manufacturer maintains design compatibility)

The HPA200X2DA qualifies as a direct substitute based on identical matching of all mandatory parameters and improved accuracy specification.

Engineering Selection Recommendations

HPA200X2DA as Primary Substitute:

The HPA200X2DA is the direct equivalent for the obsolete HPA100X2DA. This substitution is supported by:

1. Functional Equivalence: All critical operational parameters match exactly, including pressure measurement range, output protocol, supply voltage, and physical interface specifications.

2. Improved Accuracy: The HPA200X2DA provides ±0.03% accuracy compared to the HPA100X2DA's ±0.06%, representing a 50% improvement in measurement precision while maintaining full compatibility.

3. Active Product Status: The HPA200X2DA is an active product, ensuring ongoing availability, technical support, and supply chain continuity.

4. Mechanical Compatibility: Identical port configuration (Female 1/8" Swagelok™ threaded), package form factor (Module Cube), and connector termination enable direct physical replacement without system redesign.

5. Environmental Specifications: Matching operating temperature range (-40°C to 85°C) and moisture sensitivity level (MSL 1) confirm suitability for identical deployment environments.

Compliance Consideration: Both parts maintain RoHS non-compliant status. Systems requiring RoHS compliance must evaluate alternative product lines outside this substitution group.

Frequently Asked Questions (FAQ)

Q: Can the HPA200X2DA replace the HPA100X2DA in existing installations?

A: Yes. The HPA200X2DA is a direct substitute with identical electrical and mechanical specifications. No system modifications are required for physical installation or electrical integration.

Q: What is the difference between these two barometer models?

A: The primary difference is accuracy specification. The HPA200X2DA provides ±0.03% accuracy versus the HPA100X2DA's ±0.06%. Both sensors measure the same pressure range (17.6 PSI), use identical RS-232 output, and share the same physical interface and operating environment specifications.

Q: Are the port connections compatible?

A: Yes. Both sensors use Female 1/8" (3.18mm) Swagelok™ threaded ports. Existing tubing and fittings designed for the HPA100X2DA connect directly to the HPA200X2DA without adapter requirements.

Q: Does the HPA200X2DA require different power supply specifications?

A: No. Both sensors operate on identical voltage supply ranges (5.5V to 30V). Existing power distribution circuits require no modification.

Q: Why is the HPA100X2DA listed as obsolete?

A: The HPA100X2DA has been superseded by the HPA200X2DA. The newer model offers improved accuracy while maintaining full backward compatibility, making it the recommended choice for new designs and replacement applications.

Q: Are there any environmental or compliance differences?

A: Both sensors operate across -40°C to 85°C and maintain MSL 1 (Unlimited) moisture sensitivity ratings. Both are RoHS non-compliant. No environmental or compliance advantages exist between the two models.

Q: What is the inventory status for these parts?

A: The HPA100X2DA (obsolete) has 743 pieces in stock. The HPA200X2DA (active) has 1107 pieces in stock, providing greater availability for ongoing procurement needs.
