The identified substitute part P51-15-A-W-MD-5V-000-000 from Amphenol SSI Technologies shares compatible electrical output characteristics (1V to 5V analog voltage), equivalent pressure measurement capability (15 PSI), and identical regulatory compliance (RoHS Compliant, EAR99 ECCN, 9026.20.4000 HTSUS).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using SA015PA1HD:

The P51-15-A-W-MD-5V-000-000 substitute part is suitable for replacement based on the following factors:

1. Regulatory Alignment: Both components maintain RoHS compliance and share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring no change in export control or tariff treatment.

2. Active Manufacturing Status: The substitute is an active product with confirmed inventory availability (756 Pcs), eliminating supply chain risk associated with the obsolete SA015PA1HD.

3. Electrical Compatibility: The substitute provides analog voltage output (1V to 5V) with ±1% accuracy and operates across an 8V to 30V supply range, supporting standard industrial control system integration.

4. Mechanical Interface: The substitute features a standard 1/8" NPT male threaded port, a common industrial pressure sensor interface suitable for direct installation in existing manifold and piping configurations.

5. Environmental Performance: Operating temperature range of -40°C to 105°C and temperature-compensated output ensure stable performance across industrial environments.

Verification Requirements:

Confirm that the existing system design accommodates the substitute's MD 4-pin termination style and that the 15 PSI absolute pressure specification aligns with application requirements.

Frequently Asked Questions (FAQ)

Q: Why is the SA015PA1HD listed as obsolete?

A: The SA015PA1HD has reached end-of-life status in Honeywell's product portfolio. While current inventory remains available (1098 units), long-term sourcing cannot be guaranteed. Identifying active substitute components ensures design continuity and supply chain stability.

Q: What makes P51-15-A-W-MD-5V-000-000 a valid substitute?

A: The substitute shares critical compatibility parameters: identical regulatory classifications (RoHS, ECCN, HTSUS), equivalent pressure measurement capability (15 PSI), standard analog voltage output (1V to 5V), and industrial-grade threaded port interface (1/8" NPT). Both components are designed for pressure sensing applications in industrial automation.

Q: Are there differences in termination style between these parts?

A: Yes. The substitute uses MD 4-pin termination, a standard industrial connector type. Verify that your system's wiring harness and connector interface are compatible with this termination style before implementation.

Q: Does the substitute require any system recalibration?

A: The substitute provides ±1% accuracy with 1V to 5V output scaling. If the original system was calibrated for the SA015PA1HD's output characteristics, verify output signal mapping to ensure correct pressure reading interpretation. No additional calibration is typically required if output ranges are equivalent.

Q: What is the difference between "Absolute" and other pressure types?

A: The substitute measures absolute pressure, meaning it references a perfect vacuum (0 PSI absolute = atmospheric pressure). Confirm that your application requires absolute pressure measurement rather than gauge pressure (referenced to atmospheric) or differential pressure measurement.

Q: Can the substitute operate in the same temperature range as the original?

A: The substitute operates from -40°C to 105°C with temperature compensation. If the original SA015PA1HD operated within this range, the substitute is suitable. Verify your application's specific temperature requirements against this specification.

Q: What does "Amplified Output" mean on the substitute?

A: Amplified output indicates the sensor includes internal signal conditioning circuitry, providing a direct 1V to 5V output signal suitable for direct connection to industrial control systems without external amplification or signal conditioning.

Q: Is the substitute RoHS compliant?

A: Yes. The P51-15-A-W-MD-5V-000-000 is RoHS compliant, matching the compliance status of the original SA015PA1HD. Both components meet environmental and hazardous substance restrictions.
