Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCC100GD2 is determined by the following critical parameters that must remain consistent or compatible:

Mandatory Matching Parameters:

• Operating pressure rating: 100PSI (689.48kPa)
• Pressure type: Vented gauge configuration
• Output type: Wheatstone Bridge
• Operating temperature range: -40°C to 85°C minimum
• Mounting type: Through hole, board mount
• Port connection: Male tube interface
• Manufacturer: Honeywell Sensing and Productivity Solutions
• RoHS compliance status

Allowable Variations:

• Output signal range (85-225 mV vs. 0-86 mV acceptable with signal conditioning)
• Accuracy specification (±0.5% vs. ±0.25% represents improvement)
• Port tube diameter (0.11" vs. 0.19" requires mechanical adapter consideration)
• Package configuration (6-DIP vs. 8-DIP affects PCB layout)
• Maximum pressure rating (150PSI vs. 250PSI represents increased safety margin)
• Supply voltage range (when specified)

The NSCDANN100PGUNV qualifies as a substitute based on matching core functional parameters while offering enhanced specifications in accuracy and maximum pressure rating.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The NSCDANN100PGUNV serves as a functional equivalent to the obsolete SCC100GD2 for applications requiring 100PSI vented gauge pressure measurement. Both components share identical core specifications: operating pressure, pressure type, output type, and operating temperature range. The substitute maintains RoHS compliance and is manufactured by the same supplier, ensuring consistency in quality and reliability standards.

Design Considerations:

1. PCB Layout Modification: The transition from 6-DIP to 8-DIP package requires PCB redesign. The NSCDANN100PGUNV features a top port configuration, affecting component placement and routing.

2. Signal Conditioning: Output signal ranges differ significantly (85-225 mV vs. 0-86 mV at 5V supply). Existing signal conditioning circuits must be evaluated and potentially redesigned to accommodate the lower output range of the substitute.

3. Mechanical Interface: Port tube diameter increases from 0.11" to 0.19", and connection style changes from barbless to barbed. Tubing and connector specifications require revision.

4. Supply Voltage: The NSCDANN100PGUNV requires defined supply voltage (1.5V-12V), whereas the original part's supply voltage was not specified. Verify system power availability.

5. Accuracy Improvement: The substitute offers ±0.25% accuracy versus ±0.5%, providing enhanced measurement precision without additional cost.

6. Overpressure Protection: Maximum pressure rating increases to 250PSI, offering greater safety margin in applications subject to pressure spikes.

Compliance Status:

Both components maintain RoHS compliance and carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory consistency for procurement and export documentation.

Frequently Asked Questions (FAQ)

Q: Can the NSCDANN100PGUNV directly replace the SCC100GD2 without modifications?

A: No. While both sensors measure 100PSI vented gauge pressure with Wheatstone Bridge output, three factors require design changes: (1) package footprint differs (6-DIP vs. 8-DIP), (2) output signal ranges differ and require signal conditioning adjustment, and (3) port tube diameter and connection style differ, requiring mechanical interface redesign.

Q: What is the primary reason the SCC100GD2 requires substitution?

A: The SCC100GD2 is obsolete and no longer manufactured. The NSCDANN100PGUNV is an active product from the same manufacturer with equivalent functional specifications.

Q: Are the output signals compatible between these two sensors?

A: No. The SCC100GD2 outputs 85-225 mV, while the NSCDANN100PGUNV outputs 0-86 mV at 5V supply. Existing analog signal conditioning circuits must be recalibrated or redesigned to accommodate the lower output range.

Q: What mechanical changes are required for the port connection?

A: The SCC100GD2 uses a 0.11" barbless male tube connection, while the NSCDANN100PGUNV uses a 0.19" barbed male tube connection. Tubing, connectors, and fittings must be updated accordingly. A mechanical adapter may be considered, but direct tubing replacement is the standard approach.

Q: Does the NSCDANN100PGUNV offer any performance advantages?

A: Yes. The substitute provides improved accuracy (±0.25% vs. ±0.5%) and higher maximum pressure rating (250PSI vs. 150PSI), offering better measurement precision and greater overpressure protection.

Q: Are both sensors RoHS compliant?

A: Yes. Both the SCC100GD2 and NSCDANN100PGUNV are RoHS compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 9026.20.4000).

Q: What supply voltage does the NSCDANN100PGUNV require?

A: The NSCDANN100PGUNV operates with supply voltage between 1.5V and 12V. Verify that your system power supply falls within this range.

Q: Can I use the same PCB for both sensors?

A: No. The package change from 6-DIP to 8-DIP with top port configuration requires PCB redesign. Pin assignments and component placement differ between the two sensors.

Q: Is the NSCDANN100PGUNV available in sufficient quantity?

A: Yes. The NSCDANN100PGUNV is an active product with current manufacturing availability, unlike the obsolete SCC100GD2.
