Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLH08KPST03A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Base product number (MLH08)
• Pressure type (Sealed Gauge)
• Operating pressure rating (8000 PSI)
• Maximum pressure rating (12,000 PSI)
• Output type (Analog Voltage)
• Output range (0.5 V to 4.5 V)
• Accuracy specification (±0.25%)
• Supply voltage range (5 V to 6 V)
• Operating temperature range (-40°C to 125°C)
• Features (Amplified Output, Temperature Compensated)
• Package type (Cylinder, Metal)
• Compliance certifications (RoHS Compliant)

Allowable Variations:

• Port connection type and size (threaded connections with different thread specifications)
• Termination style (connector type)
• Packaging format (Bulk vs. other formats)
• Product status (Active substitutes for Obsolete originals)

The MLH08KPSB01A qualifies as a direct substitute based on complete parameter alignment across all mandatory criteria, with the primary difference being the port connection specification (1/4" NPT versus M14 x 1.5) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MLH08KPSB01A is the qualified substitute for the obsolete MLH08KPST03A based on complete functional and electrical equivalence. Both components share identical pressure ratings, output specifications, accuracy, temperature range, and supply voltage requirements. The substitute maintains RoHS compliance and active product status, ensuring continued availability and regulatory alignment.

Selection Considerations:

Port connection differences require mechanical interface evaluation. The original MLH08KPST03A uses M14 x 1.5 metric threading, while the MLH08KPSB01A employs 1/4" NPT (National Pipe Thread) standard. System integration must account for adapter requirements or port redesign if direct mechanical substitution is required.

The MLH08KPSB01A includes specified Packard Metripak 150 termination, providing standardized electrical connection. This active product status ensures long-term component availability, manufacturing support, and compliance with current regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can MLH08KPSB01A directly replace MLH08KPST03A without modification?

A: Electrical and functional compatibility is complete. Mechanical compatibility depends on port connection requirements. The M14 x 1.5 threaded port on the original differs from the 1/4" NPT port on the substitute. System integration may require adapter fittings or port redesign.

Q: What are the key parameters that define substitution eligibility?

A: Substitutes must maintain identical pressure ratings (8000 PSI operating, 12,000 PSI maximum), sealed gauge pressure type, 0.5 V to 4.5 V analog output, ±0.25% accuracy, 5 V to 6 V supply voltage, -40°C to 125°C operating temperature, amplified output with temperature compensation, and metal cylinder packaging. Variations in port type and termination style are allowable.

Q: Why is the original MLH08KPST03A classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The MLH08KPSB01A maintains identical functional specifications while offering active product status, ensuring continued manufacturing support and regulatory compliance.

Q: Are there compliance differences between the two parts?

A: Both components are RoHS Compliant. The substitute includes REACH Unaffected status. No compliance barriers exist for substitution.

Q: What is the significance of the Packard Metripak 150 termination on the substitute?

A: This termination style provides standardized electrical connection compatible with common industrial automation connector systems. Electrical signal integrity and output characteristics remain identical to the original specification.

Q: How should port connection differences be addressed in system design?

A: Evaluate existing system port specifications. If M14 x 1.5 threading is required, mechanical adapters are available. Alternatively, system redesign to accommodate 1/4" NPT threading may be appropriate for new installations.
