Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1471-015A-T is determined by alignment of the following critical parameters:

Pressure Measurement Characteristics: Operating pressure of 15PSI (103.42kPa) absolute, maximum pressure rating of 45PSI (310.26kPa), and Wheatstone Bridge output configuration must be maintained.

Electrical Specifications: Supply voltage range, output voltage range, and accuracy rating determine functional compatibility. The substitute must operate within the specified temperature range of -40°C to 125°C.

Mechanical and Interface Requirements: Port size, port style (barbless), and mounting type (surface mount) define physical compatibility with existing circuit board designs and pneumatic connections.

Packaging and Compliance: Surface mount package type, RoHS compliance status, and moisture sensitivity level affect assembly processes and regulatory requirements.

The Amphenol NovaSensor NPP-301B-100A meets the core substitution criteria of absolute pressure measurement at 15PSI with Wheatstone Bridge output, identical temperature range, and surface mount configuration. Differences in port size, output voltage range, supply voltage range, package footprint, and termination style require engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 1471-015A-T is classified as obsolete. The NPP-301B-100A is an active product with current manufacturing support and availability, making it suitable for new designs and long-term procurement strategies.

Compliance and Regulatory: Both components are RoHS compliant. The 1471-015A-T carries RoHS3 compliance, while the NPP-301B-100A carries RoHS compliance. Both components are classified under ECCN EAR99 and HTSUS 9026.20.4000.

Moisture Sensitivity: The 1471-015A-T has MSL 1 (Unlimited), indicating no time-based storage restrictions. The NPP-301B-100A has MSL 6 (Time on Label), requiring adherence to moisture exposure time limits during assembly. This difference affects handling and storage protocols.

Electrical and Mechanical Compatibility: Selection between these components depends on circuit design specifications. The 1471-015A-T operates on 5V to 12V supply with 65 mV output, while the NPP-301B-100A operates on 3V to 10V supply with 60 mV output. Port size differs (0.09" versus 0.08" tube diameter), and package footprints differ (8-SMD No Lead Top Port versus 8-SOIC). Termination styles differ (SMD Tab versus Gull Wing), affecting PCB layout and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the NPP-301B-100A directly replace the 1471-015A-T without circuit modifications?

A: Direct replacement requires evaluation of three factors: (1) Supply voltage compatibility—the NPP-301B-100A operates on 3V to 10V versus the 1471-015A-T's 5V to 12V range; (2) Output voltage scaling—the NPP-301B-100A produces 60 mV output versus 65 mV, requiring signal conditioning adjustment; (3) Package footprint and termination style differences necessitate PCB layout changes.

Q: What are the port size implications for substitution?

A: The 1471-015A-T uses a 0.09" (2.29mm) male barbless tube port, while the NPP-301B-100A uses a 0.08" (2.04mm) male barbless tube port with dual configuration. Pneumatic tubing compatibility must be verified. The smaller port diameter of the NPP-301B-100A may require adapter fittings or tubing size adjustment.

Q: How does the moisture sensitivity difference affect component handling?

A: The 1471-015A-T with MSL 1 has unlimited shelf life without moisture exposure restrictions. The NPP-301B-100A with MSL 6 requires time-on-label tracking during storage and assembly. Exposure to moisture beyond specified time limits requires baking procedures before soldering.

Q: Are the accuracy specifications compatible for the application?

A: The 1471-015A-T provides ±0.25% accuracy, while the NPP-301B-100A provides ±0.2% accuracy. The NPP-301B-100A offers superior accuracy. Both accuracies are suitable for 15PSI absolute pressure measurement applications, but system calibration requirements must be evaluated.

Q: What package considerations affect assembly and design?

A: The 1471-015A-T uses 8-SMD No Lead Top Port configuration with SMD Tab termination. The NPP-301B-100A uses 8-SOIC (0.154", 3.90mm Width) configuration with Gull Wing termination. These differences affect PCB trace routing, solder reflow profiles, and automated assembly equipment compatibility.

Q: Is the NPP-301B-100A suitable for new product designs?

A: Yes. The NPP-301B-100A is an active product with current manufacturing support. The 1471-015A-T is obsolete. For new designs, the NPP-301B-100A is the appropriate selection, provided electrical and mechanical specifications align with system requirements.
