Key Parameters

Substitute Part Grouping Explanation

Substitution of the MLH250BST08E is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure of 2000 PSI and maximum pressure rating of 4000 PSI must be maintained.

Output Characteristics: Analog current output with 4 mA to 20 mA range is mandatory for circuit compatibility.

Electrical Requirements: Supply voltage range of 9.5V to 30V and accuracy of ±0.25% must be preserved.

Environmental Tolerance: Operating temperature range of -40°C to 125°C must be supported.

Pressure Measurement Type: Sealed gauge pressure measurement must be retained.

Regulatory Compliance: RoHS compliance status must be maintained.

The MLH02KPSP01B qualifies as a substitute based on matching all critical parameters listed above. Differences in termination style (Flying Lead versus Connector), port size specification (Male 1/4" NPT versus unspecified), packaging format (Bulk versus standard), and additional features (Amplified Output, Temperature Compensated) represent secondary variations that do not affect functional equivalence for pressure measurement applications.

Parameter Comparison

Engineering Selection Recommendations

The MLH02KPSP01B is the qualified substitute for the obsolete MLH250BST08E based on functional parameter equivalence. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain identical specifications for pressure measurement, output characteristics, electrical requirements, and environmental operating conditions.

The MLH02KPSP01B carries Active product status, ensuring ongoing manufacturer support and availability. Both parts maintain RoHS compliance, satisfying regulatory requirements for industrial automation applications.

The primary engineering consideration is the difference in termination style: the MLH250BST08E uses a Connector termination, while the MLH02KPSP01B uses Flying Lead termination. This difference requires evaluation of the existing circuit interface and potential wiring modifications during component replacement.

The MLH02KPSP01B includes amplified output and temperature compensation features not specified in the MLH250BST08E documentation. These additional features do not create incompatibility and may provide enhanced performance characteristics in the target application.

Frequently Asked Questions (FAQ)

Q: Can the MLH02KPSP01B directly replace the MLH250BST08E without circuit modifications?

A: Both components share identical pressure specifications, output range (4 mA to 20 mA), accuracy (±0.25%), supply voltage (9.5V to 30V), and operating temperature range (-40°C to 125°C). The primary difference is termination style: Connector versus Flying Lead. Circuit interface compatibility must be verified based on the existing connector or wiring configuration.

Q: What is the significance of the different termination styles?

A: The MLH250BST08E uses a Connector termination, while the MLH02KPSP01B uses Flying Lead termination. This affects how the sensor connects to the circuit. Connector-based systems use standardized connectors, while Flying Lead systems require direct wire connections. The selection depends on the existing circuit design and installation requirements.

Q: Are both parts RoHS compliant?

A: Yes, both the MLH250BST08E and MLH02KPSP01B are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What does "Sealed Gauge" pressure type mean?

A: Sealed gauge pressure measurement indicates the sensor measures pressure relative to a sealed reference chamber rather than atmospheric pressure. Both components use this measurement type, ensuring functional equivalence.

Q: Why is the MLH250BST08E classified as obsolete?

A: The MLH250BST08E is listed as obsolete, indicating the manufacturer has discontinued production. The MLH02KPSP01B, classified as Active, represents the current production alternative with equivalent functional specifications.

Q: Does the MLH02KPSP01B's amplified output feature affect compatibility?

A: The amplified output and temperature compensation features of the MLH02KPSP01B are additional capabilities that do not create incompatibility with circuits designed for the MLH250BST08E. These features may enhance signal quality and temperature stability in the application.

Q: What is the port size difference between these components?

A: The MLH250BST08E does not specify a port size in the provided documentation. The MLH02KPSP01B specifies Male 1/4" (6.35mm) NPT threaded port. Port compatibility must be verified against the existing system installation requirements.
