Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCC15ASMTT is determined by the following critical parameters that must align across candidate parts:

Mandatory Matching Parameters:

• Pressure Type: Absolute
• Operating Pressure: 15PSI (103.42kPa)
• Maximum Pressure: 30PSI (206.84kPa)
• Output Type: Wheatstone Bridge
• Operating Temperature Range: -40°C ~ 125°C
• Mounting Type: Surface Mount
• Termination Style: SMD (SMT) Tab

Allowable Variations:

• Output Range: May differ due to supply voltage differences
• Accuracy: May improve (lower tolerance values acceptable)
• Package Configuration: May vary (6-SMD, 8-SMD acceptable if SMD termination maintained)
• Port Configuration: May differ based on application requirements
• Supply Voltage: May vary if output scaling accommodates system requirements

The NBPLLNN015PAUNV qualifies as a substitute based on matching pressure specifications, output type, temperature range, and SMD termination, despite differences in package configuration and output voltage range.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The NBPLLNN015PAUNV is a valid substitute for the obsolete SCC15ASMTT based on matching core pressure specifications (15PSI absolute, 30PSI maximum), identical output type (Wheatstone Bridge), and compatible operating temperature range (-40°C ~ 125°C). Both components utilize SMD termination for surface mount applications.

Key Considerations:

1. Product Status: The NBPLLNN015PAUNV is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete SCC15ASMTT.

2. Compliance: The NBPLLNN015PAUNV carries RoHS Compliant certification, meeting current regulatory requirements for electronic components in regulated industries.

3. Output Characteristics: The substitute provides improved accuracy (±0.25% versus ±1%), which is advantageous for precision applications. However, the output voltage range differs (0 mV ~ 75 mV at 5V supply versus 40 mV ~ 95 mV). Signal conditioning circuits must be evaluated to confirm compatibility with existing measurement electronics.

4. Package and Port Configuration: The substitute uses a 6-SMD package with a top-mounted barbless male tube port (0.13" / 3.18mm), compared to the main part's 8-SMD module with no port. PCB layout modifications may be required to accommodate the different package footprint and port configuration.

5. Supply Voltage: The substitute specifies a supply voltage range of 1.8V ~ 12V, providing flexibility for various system architectures. The main part's supply voltage was not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the NBPLLNN015PAUNV directly replace the SCC15ASMTT without circuit modifications?

A: Direct replacement requires evaluation of signal conditioning circuits. While both components output Wheatstone Bridge signals, the voltage ranges differ (40-95 mV versus 0-75 mV). PCB layout changes are necessary due to different package configurations (8-SMD versus 6-SMD) and port styles (no port versus barbless tube port).

Q: What is the significance of the improved accuracy specification in the substitute part?

A: The NBPLLNN015PAUNV provides ±0.25% accuracy compared to the SCC15ASMTT's ±1% accuracy. This represents a four-fold improvement in measurement precision and is acceptable for applications requiring higher accuracy. No circuit modifications are needed to accommodate improved accuracy.

Q: Are there supply voltage compatibility issues between these parts?

A: The SCC15ASMTT's supply voltage was not specified in available documentation. The NBPLLNN015PAUNV requires 1.8V ~ 12V supply. System designers must confirm that existing power supplies fall within this range. The substitute's wider voltage range typically provides greater design flexibility.

Q: How do the port configurations affect substitution?

A: The SCC15ASMTT has no port (sealed design), while the NBPLLNN015PAUNV features a barbless male tube port for 0.13" (3.18mm) tubing. Application requirements determine compatibility. Sealed applications require the no-port configuration; applications requiring pressure line connections need the ported version. These are fundamentally different mechanical interfaces.

Q: What PCB layout changes are required for substitution?

A: The package change from 8-SMD Module to 6-SMD, No Lead, Top Port requires new footprint design. The top-mounted port on the substitute may affect component placement density and routing. Mechanical clearance around the port must be verified in the target PCB layout.

Q: Is the NBPLLNN015PAUNV suitable for the same temperature range applications?

A: Yes. Both components operate across -40°C ~ 125°C, providing identical thermal performance specifications. No temperature-related limitations exist for substitution.

Q: What is the significance of RoHS compliance on the substitute part?

A: RoHS Compliance on the NBPLLNN015PAUNV ensures the component meets Restriction of Hazardous Substances regulations, required for many regulated markets and industries. The main part's RoHS status was not specified. This compliance status is advantageous for new designs and regulated applications.
