SCC100D Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCC100D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 100PSI (689.48kPa) differential pressure range and Wheatstone Bridge output. The sensor operates across -40°C to 85°C and features temperature compensation with ±0.5% accuracy.

The SCC100D is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support legacy equipment maintenance where direct replacement with the original part number is no longer feasible.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCC100D is based on the following critical parameters that must align between the main part and substitute candidates:

Pressure Measurement Capability: The substitute must support differential pressure measurement at or above 100PSI operating range.

Output Signal Type: The substitute must provide Wheatstone Bridge output to maintain compatibility with existing signal conditioning and measurement circuits.

Operating Temperature Range: The substitute must cover the full -40°C to 85°C operating window.

Mounting and Termination: The substitute must use through-hole mounting with PC pin termination to ensure mechanical and electrical compatibility with existing PCB layouts.

Electrical Interface: The substitute must operate within compatible voltage supply ranges and produce output signals compatible with downstream electronics.

The NSCSSNN100PDUNV meets these substitution criteria. It provides differential pressure measurement with ±100PSI range (exceeding the 100PSI requirement), Wheatstone Bridge output, identical operating temperature range, through-hole mounting with PC pin termination, and operates on 1.5V ~ 12V supply voltage.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCC100D is obsolete, making the NSCSSNN100PDUNV the appropriate active alternative from the same manufacturer. The substitute is currently in production with established supply chain availability.

Compliance Alignment: Both parts are RoHS Compliant and REACH Unaffected, maintaining regulatory compliance for new designs and legacy system updates.

Functional Compatibility: The NSCSSNN100PDUNV provides equivalent differential pressure measurement capability with superior accuracy (±0.25% versus ±0.5%) and higher overpressure rating (±250PSI versus 150PSI).

Implementation Considerations: Direct substitution requires two modifications: (1) PCB layout adjustment due to package change from 5-DIP to 4-SIP, and (2) signal conditioning circuit adjustment to accommodate the different output voltage range (0 mV ~ 172.5 mV versus 85 mV ~ 225 mV).

Supply Voltage: Verify that the system power supply falls within the NSCSSNN100PDUNV operating range of 1.5V ~ 12V. The original SCC100D supply voltage specification is not provided in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN100PDUNV be used as a direct drop-in replacement for the SCC100D?

A: No. While both sensors provide differential pressure measurement with Wheatstone Bridge output and identical operating temperature ranges, the NSCSSNN100PDUNV requires PCB layout modification due to package change (5-DIP to 4-SIP) and signal conditioning adjustment for the different output voltage range.

Q: What is the key difference in output signal between these two sensors?

A: The SCC100D outputs 85 mV ~ 225 mV, while the NSCSSNN100PDUNV outputs 0 mV ~ 172.5 mV at 5V supply. Downstream signal conditioning circuits must be recalibrated to accommodate this difference.

Q: Does the NSCSSNN100PDUNV provide better performance than the SCC100D?

A: The NSCSSNN100PDUNV offers improved accuracy (±0.25% versus ±0.5%) and higher overpressure protection (±250PSI versus 150PSI). Both sensors maintain identical operating temperature range and pressure measurement type.

Q: Are both sensors RoHS compliant?

A: Yes. Both the SCC100D and NSCSSNN100PDUNV are RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What supply voltage does the NSCSSNN100PDUNV require?

A: The NSCSSNN100PDUNV operates on 1.5V ~ 12V supply voltage. Verify that your system power supply falls within this range before implementation.

Q: Why is the SCC100D listed as obsolete?

A: The SCC100D has been discontinued by Honeywell Sensing and Productivity Solutions. The NSCSSNN100PDUNV from the TruStability® NSC series represents the active product line for equivalent differential pressure sensing applications.

Q: Can I use the NSCSSNN100PDUNV in the same PCB footprint as the SCC100D?

A: No. The SCC100D uses a 5-DIP Module package, while the NSCSSNN100PDUNV uses a 4-SIP Module package. PCB layout modification is required for mechanical and electrical compatibility.
