SCCP30GSMTP Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCCP30GSMTP is a surface-mount pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board-level applications requiring vented gauge pressure measurement at 30PSI (206.84kPa). This component features a Wheatstone Bridge output with temperature compensation and operates across an extended temperature range of -40°C to 125°C.

The SCCP30GSMTP is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the SCCP30GSMTP is based on the following critical parameters that define functional equivalence:

Pressure Specification Match:

• Operating pressure: 30PSI (206.84kPa)
• Pressure type: Vented Gauge
• Maximum pressure rating: 60PSI (413.69kPa)

Output Characteristics:

• Output type: Wheatstone Bridge
• Pressure range alignment within specified operating envelope

Mechanical Interface:

• Port size: Male tube connection at 0.08" nominal diameter
• Port style compatibility

Environmental Compliance:

• RoHS Compliance requirement
• Operating temperature range capability

Application Context:

• Board-mount pressure sensing applications
• Vented gauge measurement requirements

The NSCDRRN030PGUNV qualifies as a substitute based on matching pressure specification (30PSI vented gauge), identical pressure type, equivalent maximum pressure rating, and RoHS compliance. However, this substitute introduces differences in mounting technology, output range, accuracy specification, and termination style that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCCP30GSMTP is obsolete, while the NSCDRRN030PGUNV is active. Active product status provides ongoing manufacturer support, documentation availability, and supply chain continuity.

Compliance Alignment: Both parts maintain RoHS Compliance and carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory consistency for applications subject to export control or environmental compliance requirements.

Critical Differences Requiring Design Evaluation:

The NSCDRRN030PGUNV introduces the following deviations from the SCCP30GSMTP specification:

• Mounting Technology: Transition from surface-mount (SMD) to through-hole (DIP) requires PCB redesign
• Output Range: Reduction from 60-150 mV to 0-103.5 mV necessitates signal conditioning circuit adjustment
• Accuracy: Improvement from ±1% to ±0.25% may reduce signal processing requirements
• Temperature Range: Reduction from -40°C to 125°C to -40°C to 85°C limits high-temperature applications
• Port Configuration: Change from single port to dual ports on same side alters mechanical integration
• Supply Voltage: Introduction of 1.5V-12V supply requirement versus unspecified supply for main part

Selection of the NSCDRRN030PGUNV as a substitute requires verification that the application can accommodate these parameter differences, particularly mounting technology, output signal range, and maximum operating temperature.

Frequently Asked Questions (FAQ)

Q: Can the NSCDRRN030PGUNV directly replace the SCCP30GSMTP without PCB modification?

A: No. The NSCDRRN030PGUNV uses through-hole (DIP) termination with PC pins, while the SCCP30GSMTP uses surface-mount (SMD) tabs. PCB redesign is required to accommodate the different mounting technology and package footprint (8-DIP at 0.524" versus 8-SMD Module).

Q: Are the pressure measurement ranges compatible?

A: Both parts measure 30PSI vented gauge pressure with identical maximum pressure ratings of 60PSI. However, the output voltage ranges differ: SCCP30GSMTP outputs 60-150 mV, while NSCDRRN030PGUNV outputs 0-103.5 mV at 5V supply. Signal conditioning circuits must be adjusted to accommodate this output range difference.

Q: What is the impact of the accuracy specification change?

A: The NSCDRRN030PGUNV provides ±0.25% accuracy compared to the SCCP30GSMTP's ±1% accuracy. This represents a fourfold improvement in measurement precision. Applications requiring the original ±1% specification may not require redesign of signal processing algorithms, but improved accuracy may enable enhanced system performance.

Q: Does the operating temperature range reduction affect suitability?

A: The NSCDRRN030PGUNV operates from -40°C to 85°C, compared to the SCCP30GSMTP's -40°C to 125°C range. Applications requiring operation above 85°C cannot use this substitute. Verify maximum ambient and operating temperatures for your specific application.

Q: What is the significance of the dual port configuration?

A: The NSCDRRN030PGUNV features dual ports on the same side, compared to the single port on the SCCP30GSMTP. This affects mechanical integration and tubing routing. Verify that your application can accommodate dual port configuration or confirm that only one port is required for operation.

Q: Are there supply voltage requirements for the substitute part?

A: Yes. The NSCDRRN030PGUNV requires a supply voltage of 1.5V to 12V. Ensure your power supply circuit can provide this voltage range. The SCCP30GSMTP supply voltage specification was not provided in the available data.

Q: Is the port size difference significant?

A: The SCCP30GSMTP uses a 0.08" (2.05mm) tube port, while the NSCDRRN030PGUNV uses a 0.08" (1.93mm) tube port with dual configuration. The 0.12mm difference is minimal, but tubing compatibility must be verified. The barbed port style on the NSCDRRN030PGUNV differs from the barbless style on the SCCP30GSMTP, affecting tubing connection method.

Q: Can I use the NSCDRRN030PGUNV in legacy systems designed for the SCCP30GSMTP?

A: Substitution requires comprehensive design review. The differences in mounting technology, output range, accuracy, temperature range, and port configuration necessitate evaluation against your specific application requirements. Direct plug-in replacement is not possible due to mounting technology differences.
