Key Parameters

Substitute Part Grouping Explanation

Substitution of the P51-15-A-UB-P-4.5V-000-000 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Pressure measurement range: 15 PSI absolute
• Output signal type: Analog voltage 0.5 V to 4.5 V
• Supply voltage: 5 V
• Accuracy specification: ±1%
• Termination interface: Packard 3-pin connector
• Operating temperature range: -40°C to 105°C
• Port thread size: 1/8" NPT

Allowable Variations:

• Port gender configuration (Female NPT to Male NPT)
• Product status (Obsolete to Active)
• Packaging format (Cylinder maintained)
• Compliance certifications (RoHS status)

The substitute part P51-15-A-W-P-4.5V-000-000 maintains all mandatory electrical and mechanical parameters while differing only in port gender (Male vs. Female NPT) and product lifecycle status.

Engineering Selection Recommendations

Primary Substitute: P51-15-A-W-P-4.5V-000-000

This part is the manufacturer-recommended equivalent for the obsolete P51-15-A-UB-P-4.5V-000-000. Selection of this substitute is based on:

1. Product Status: The substitute maintains Active product status, ensuring long-term availability and continued manufacturer support compared to the Obsolete designation of the original part.

2. Electrical Equivalence: All electrical parameters are identical, including 15 PSI absolute pressure measurement, 0.5 V to 4.5 V output range, 5 V supply voltage, and ±1% accuracy specification.

3. Mechanical Compatibility: Both parts utilize identical 1/8" NPT threaded port size and Packard 3-pin termination, ensuring connector and mounting compatibility.

4. Compliance: The substitute part carries RoHS Compliant certification, meeting current regulatory requirements for electronic components in industrial applications.

5. Port Gender Consideration: The substitute features Male NPT port configuration versus the Female NPT of the original part. Port gender selection depends on the mating connector type in the installation. Verify the existing system connection type before substitution.

6. Thermal Performance: Operating temperature range remains -40°C to 105°C, maintaining thermal specifications for industrial automation environments.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between P51-15-A-UB-P-4.5V-000-000 and P51-15-A-W-P-4.5V-000-000?

A: The primary difference is port gender configuration. The original part (UB) features Female 1/8" NPT, while the substitute (W) features Male 1/8" NPT. All electrical specifications and pressure measurement capabilities are identical. Port gender selection depends on the mating connector type in your system.

Q: Can I directly replace the obsolete part with the substitute without system modifications?

A: Direct replacement is possible if your system uses a Female NPT mating connector. If your system uses a Male NPT connector, an adapter or system modification is required. Verify your existing port configuration before substitution.

Q: Are the electrical outputs identical between these two parts?

A: Yes. Both parts provide 0.5 V to 4.5 V analog voltage output with ±1% accuracy, 5 V supply voltage requirement, and identical signal conditioning with amplified output and temperature compensation.

Q: Why is the substitute part recommended over the original?

A: The substitute part (P51-15-A-W-P-4.5V-000-000) is manufacturer-recommended because it maintains Active product status with continued availability, while the original part is classified as Obsolete. The substitute also carries RoHS Compliant certification.

Q: Are the termination connectors compatible?

A: Yes. Both parts use identical Packard 3-pin termination style, ensuring connector compatibility without modification.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 105°C, suitable for industrial automation environments with wide temperature variations.

Q: Does the substitute part require different mounting hardware?

A: No. Both parts use identical 1/8" NPT threaded port size and Cylinder package type. Mounting hardware and thread specifications remain unchanged.
