Substitute Part Grouping Explanation

Substitution eligibility for the MLH02KPSD01A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Pressure Type: Sealed Gauge
Operating Pressure: 2000 PSI (13789.51 kPa)
Maximum Pressure: 4000 PSI (27579.03 kPa)
Output Type: Analog Voltage
Output Range: 0.5 V to 4.5 V
Accuracy: ±0.25%
Supply Voltage: 5V to 6V
Port Size: Male - 1/4" (6.35 mm) NPT
Port Style: Threaded
Operating Temperature Range: -40°C to 125°C
Package Type: Cylinder, Metal
Features: Amplified Output, Temperature Compensated

The MLH02KPSL01A meets all mandatory matching parameters and qualifies as a direct substitute. The primary distinction is product status: MLH02KPSL01A is active, whereas MLH02KPSD01A is obsolete. Both units share identical electrical and mechanical specifications within the MLH series.

Engineering Selection Recommendations

The MLH02KPSL01A is the direct substitute for the obsolete MLH02KPSD01A. Selection is based on the following engineering criteria:

Product Status Alignment: The MLH02KPSL01A maintains active product status with Honeywell, ensuring ongoing availability, technical support, and compliance with current manufacturing standards.

Electrical and Mechanical Equivalence: Both units are identical across all critical operating parameters: pressure range, output characteristics, accuracy, supply voltage, and temperature operating envelope. The sealed gauge pressure type and 1/4" NPT threaded port configuration are preserved.

Compliance Certification: Both parts maintain RoHS compliance and identical moisture sensitivity ratings (MSL 1), confirming regulatory equivalence for industrial automation applications.

Termination Consideration: The MLH02KPSL01A includes a 1m cable termination, whereas the main part specification does not detail termination style. This represents the only functional difference and does not affect pressure sensing performance or electrical output characteristics.

Frequently Asked Questions (FAQ)

Q: Can MLH02KPSL01A directly replace MLH02KPSD01A in existing installations?

A: Yes. The MLH02KPSL01A is electrically and mechanically equivalent to MLH02KPSD01A. Both units share identical pressure ranges (0-2000 PSI operating, 4000 PSI maximum), output specifications (0.5-4.5V analog), accuracy (±0.25%), supply voltage (5-6V), and port configuration (1/4" NPT male threaded). Physical mounting and electrical connection are compatible.

Q: What is the primary reason for substitution?

A: MLH02KPSD01A is classified as obsolete. MLH02KPSL01A is the active equivalent within the MLH series, ensuring continued supply chain availability and manufacturer support.

Q: Are there differences in accuracy or temperature performance?

A: No. Both units maintain ±0.25% accuracy and operate across the identical temperature range of -40°C to 125°C with temperature compensation.

Q: Does the 1m cable termination on MLH02KPSL01A affect compatibility?

A: The cable termination is an interface specification that does not affect pressure sensing performance or electrical output. Integration into existing systems depends on connector compatibility with the receiving circuit. The core sensor functionality remains unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both MLH02KPSD01A and MLH02KPSL01A are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: What pressure ranges are supported?

A: Both units operate at 2000 PSI (13789.51 kPa) nominal with a maximum pressure rating of 4000 PSI (27579.03 kPa). The sealed gauge pressure type is maintained in both variants.
