MLH500PST02A Equivalent & Substitute Parts Reference

Part Overview

The MLH500PST02A is an all-metal pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for sealed gauge pressure measurement in industrial automation applications. This component features amplified analog voltage output with temperature compensation and operates across a wide temperature range from -40°C to 125°C.

The MLH500PST02A is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support ongoing maintenance and replacement requirements for existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLH500PST02A is determined by strict alignment of the following critical parameters:

Pressure Specifications: Operating pressure of 500 PSI and sealed gauge pressure type must be maintained. The substitute part must support the same nominal pressure rating.

Electrical Interface: Output type must be analog voltage with output range of 0.5 V to 4.5 V. Accuracy specification of ±0.25% must be preserved.

Supply Voltage: The substitute part must operate within compatible supply voltage ranges. The MLH500PST02A requires 5 V to 6 V; substitute parts must support this range or a compatible subset.

Mechanical Interface: Port size (Male M12 x 1.5) and threaded port style must match to ensure direct installation compatibility.

Environmental Performance: Operating temperature range of -40°C to 125°C and temperature compensation feature must be maintained.

Regulatory Compliance: RoHS compliance status must be equivalent or superior.

The PX2AM1XX500PSAAX meets these substitution criteria across all critical parameters.

Engineering Selection Recommendations

PX2AM1XX500PSAAX as Primary Substitute

The PX2AM1XX500PSAAX is the qualified substitute for the obsolete MLH500PST02A. This recommendation is based on the following engineering factors:

Product Status: The PX2AM1XX500PSAAX carries active product status, ensuring ongoing manufacturer support, availability, and supply chain reliability compared to the obsolete MLH500PST02A.

Electrical Compatibility: Both parts deliver identical analog voltage output (0.5 V to 4.5 V) with matching ±0.25% accuracy. The PX2AM1XX500PSAAX supply voltage range (4.75 V to 5.25 V) is a subset of the MLH500PST02A range (5 V to 6 V), ensuring functional compatibility in systems designed for the original part.

Mechanical Interface: Identical M12 x 1.5 threaded male port configuration enables direct installation without mechanical adaptation.

Pressure and Temperature Performance: Both parts operate at 500 PSI sealed gauge pressure with identical -40°C to 125°C temperature range and temperature compensation features.

Regulatory Compliance: Both parts maintain RoHS compliance status.

Design Consideration: The PX2AM1XX500PSAAX has a lower maximum pressure rating (1000 PSI versus 1500 PSI). This difference is not a substitution barrier for applications operating at the nominal 500 PSI specification, but must be evaluated if the system design relies on the higher overpressure protection margin of the original part.

Frequently Asked Questions (FAQ)

Q: Can the PX2AM1XX500PSAAX directly replace the MLH500PST02A without circuit modifications?

A: Yes. Both parts provide identical analog voltage output (0.5 V to 4.5 V) with matching accuracy (±0.25%). The PX2AM1XX500PSAAX supply voltage range (4.75 V to 5.25 V) is compatible with systems designed for the MLH500PST02A (5 V to 6 V). No circuit modifications are required for electrical interface compatibility.

Q: Are the mechanical connections identical?

A: Yes. Both parts feature Male M12 x 1.5 threaded ports, enabling direct installation without mechanical adaptation or port conversion.

Q: What is the significance of the different maximum pressure ratings?

A: The MLH500PST02A has a maximum pressure rating of 1500 PSI, while the PX2AM1XX500PSAAX is rated to 1000 PSI. Both parts operate at the same nominal 500 PSI specification. The difference in maximum pressure represents the overpressure protection margin. For applications operating strictly at 500 PSI sealed gauge pressure, this difference does not affect functional performance. Applications requiring the higher overpressure margin must evaluate system requirements.

Q: Why is the MLH500PST02A classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support for this part number. The PX2AM1XX500PSAAX, with active product status, represents the current equivalent offering from Honeywell Sensing and Productivity Solutions.

Q: Are both parts RoHS compliant?

A: Yes. Both the MLH500PST02A and PX2AM1XX500PSAAX are RoHS compliant.

Q: What is the packaging difference between these parts?

A: The MLH500PST02A is supplied in standard packaging, while the PX2AM1XX500PSAAX is supplied in bulk packaging. Both are suitable for component integration; packaging selection depends on procurement and inventory management requirements.

Q: Do both parts include temperature compensation?

A: Yes. Both the MLH500PST02A and PX2AM1XX500PSAAX include temperature compensation features and operate across the identical -40°C to 125°C temperature range.
