SCC100DN Equivalent & Substitute Parts Reference

Part Overview

The SCC100DN is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 100PSI (689.48kPa) differential pressure measurement. The sensor outputs a Wheatstone Bridge signal in the range of 85 mV to 225 mV and operates across -40°C to 85°C.

The SCC100DN is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCC100DN is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Compatibility Criteria:

• Pressure measurement type: Differential
• Operating pressure range: 100PSI nominal (±100PSI acceptable)
• Output type: Wheatstone Bridge configuration
• Temperature operating range: -40°C to 85°C minimum
• Manufacturer: Honeywell Sensing and Productivity Solutions
• Mounting: Through Hole, board mount applications
• Regulatory compliance: RoHS Compliant

Secondary Considerations:

• Port size and style (barbed connections)
• Output signal voltage range (must be compatible with receiving circuitry)
• Accuracy specification (±0.5% or better)
• Package form factor (DIP or SIP modules)

The NSCSHHN100PDUNV meets these criteria as a direct substitute, sharing the same differential pressure measurement principle, operating temperature range, Wheatstone Bridge output, and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The NSCSHHN100PDUNV is a functionally equivalent substitute for the obsolete SCC100DN based on the following engineering factors:

Functional Equivalence: Both sensors measure differential pressure at 100PSI nominal operating point using identical Wheatstone Bridge output architecture. Both operate across the -40°C to 85°C temperature range and maintain RoHS compliance.

Regulatory and Compliance Alignment: Both parts are manufactured by Honeywell Sensing and Productivity Solutions and carry RoHS Compliant and REACH Unaffected designations. Both are classified under HTSUS 9026.20.4000 and ECCN EAR99.

Design Integration Considerations: The NSCSHHN100PDUNV is an active product with current manufacturing support, eliminating obsolescence risk. However, three design modifications are necessary:

1. Output Signal Conditioning: The substitute outputs 0 mV ~ 172.5 mV (5V supply) versus the original 85 mV ~ 225 mV. Signal conditioning or amplification circuitry must be adapted to accommodate this voltage range difference.

2. Package Footprint: The substitute uses a 4-SIP module versus the original 5-DIP module. PCB layout and pin assignment must be redesigned.

3. Pneumatic Interface: The substitute uses 0.16" (3.94mm) barbed ports versus 0.19" (4.8mm) on the original. Tubing adapters or new tubing specifications are required.

Accuracy Improvement: The substitute offers ±0.25% accuracy compared to the original ±0.5%, providing enhanced measurement precision without additional cost.

Frequently Asked Questions (FAQ)

Q: Can the NSCSHHN100PDUNV be used as a direct drop-in replacement for the SCC100DN?

A: No. While both sensors measure 100PSI differential pressure using Wheatstone Bridge output, three modifications are required: (1) signal conditioning for the different output voltage range, (2) PCB layout redesign for the different package form (4-SIP versus 5-DIP), and (3) pneumatic interface adaptation for the different port sizes (0.16" versus 0.19" tube diameter).

Q: What is the primary reason the SCC100DN requires substitution?

A: The SCC100DN is classified as obsolete. The NSCSHHN100PDUNV is an active product with current manufacturing support from Honeywell, ensuring long-term supply chain reliability and availability.

Q: Are the output signal ranges compatible between these two sensors?

A: No. The SCC100DN outputs 85 mV ~ 225 mV, while the NSCSHHN100PDUNV outputs 0 mV ~ 172.5 mV at 5V supply. Receiving circuitry must be modified to accommodate the different voltage range and supply requirements.

Q: Do both sensors operate across the same temperature range?

A: Yes. Both the SCC100DN and NSCSHHN100PDUNV operate from -40°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: What is the difference in accuracy between these sensors?

A: The SCC100DN specifies ±0.5% accuracy, while the NSCSHHN100PDUNV specifies ±0.25% accuracy. The substitute provides improved measurement precision.

Q: Are there supply voltage differences between these sensors?

A: Yes. The NSCSHHN100PDUNV requires 1.5V ~ 12V supply voltage, which is explicitly specified. The SCC100DN supply voltage is not provided in the available documentation. Verify the original design supply voltage before substitution.

Q: Can standard tubing be used with the NSCSHHN100PDUNV if the original system used 0.19" tubing?

A: No. The NSCSHHN100PDUNV uses 0.16" (3.94mm) barbed ports. Either new tubing sized for 0.16" connections or mechanical adapters must be used.

Q: Is the NSCSHHN100PDUNV RoHS compliant?

A: Yes. The NSCSHHN100PDUNV is RoHS Compliant and REACH Unaffected, matching the compliance status of the original SCC100DN.

Q: What is the package difference between these sensors?

A: The SCC100DN uses a 5-DIP Module package, while the NSCSHHN100PDUNV uses a 4-SIP (Single In-line Package) with dual ports on the same side. PCB footprint and pin layout must be redesigned.
