SCC05GD2 Equivalent & Substitute Parts

Part Overview

The SCC05GD2 is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 5PSI (34.47kPa) pressure measurement. This sensor features a Wheatstone Bridge output with 25 mV to 65 mV signal range and operates across -40°C to 85°C. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

The NSCDANN005PGUNV qualifies as a substitute for the SCC05GD2 based on the following critical parameters:

Matching Parameters:

• Identical operating pressure specification: 5PSI (34.47kPa)
• Identical pressure type: Vented Gauge
• Identical output type: Wheatstone Bridge
• Identical maximum pressure rating: 20PSI (137.9kPa)
• Identical operating temperature range: -40°C to 85°C
• Identical mounting type: Through Hole
• Same manufacturer: Honeywell Sensing and Productivity Solutions
• Both RoHS Compliant

Differing Parameters:

• Package configuration: 6-DIP Module (SCC05GD2) versus 8-DIP (0.524", 13.30mm) Top Port (NSCDANN005PGUNV)
• Output signal range: 25 mV ~ 65 mV (SCC05GD2) versus 0 mV ~ 75 mV (NSCDANN005PGUNV)
• Accuracy: ±0.5% (SCC05GD2) versus ±0.25% (NSCDANN005PGUNV)
• Port size: Male 0.11" (2.67mm) Tube (SCC05GD2) versus Male 0.19" (4.93mm) Tube (NSCDANN005PGUNV)
• Supply voltage: Not specified (SCC05GD2) versus 1.5V ~ 12V (NSCDANN005PGUNV)

Parameter Comparison

Engineering Selection Recommendations

The NSCDANN005PGUNV serves as the active equivalent for the obsolete SCC05GD2. Both sensors maintain identical core pressure measurement specifications (5PSI operating pressure, vented gauge configuration, Wheatstone Bridge output, and -40°C to 85°C operating range).

The NSCDANN005PGUNV offers improved accuracy (±0.25% versus ±0.5%) and an expanded output signal range (0 mV ~ 75 mV versus 25 mV ~ 65 mV). The substitute features an 8-DIP package with top port configuration, differing from the 6-DIP module of the original part. Port size differs (0.19" versus 0.11" tube diameter), requiring mechanical interface verification during integration.

Both components are RoHS Compliant and manufactured by Honeywell Sensing and Productivity Solutions. The NSCDANN005PGUNV's active product status ensures ongoing availability and technical support.

Frequently Asked Questions (FAQ)

Q: Can NSCDANN005PGUNV directly replace SCC05GD2 in existing designs?

A: Functional substitution is possible based on matching pressure specifications and output type. However, physical integration requires verification due to package differences (6-DIP versus 8-DIP), port size variation (0.11" versus 0.19" tube), and port configuration (standard versus top port). PCB layout and mechanical mounting must be evaluated.

Q: What are the key compatibility criteria for this substitution?

A: The critical matching parameters are operating pressure (5PSI), pressure type (vented gauge), output type (Wheatstone Bridge), maximum pressure rating (20PSI), operating temperature range (-40°C to 85°C), and mounting type (through hole). These parameters ensure functional equivalence for pressure measurement applications.

Q: How do the output signal ranges differ between these sensors?

A: The SCC05GD2 outputs 25 mV to 65 mV, while the NSCDANN005PGUNV outputs 0 mV to 75 mV at 5V supply. The substitute provides a wider output range and requires supply voltage specification (1.5V to 12V). Signal conditioning and calibration curves must be adjusted accordingly.

Q: What is the significance of the accuracy difference?

A: The NSCDANN005PGUNV provides ±0.25% accuracy compared to the SCC05GD2's ±0.5%. This represents improved measurement precision in the substitute component, beneficial for applications requiring tighter tolerance control.

Q: Are there mechanical interface considerations for substitution?

A: Yes. The port size differs (0.11" versus 0.19" tube diameter), requiring verification of tubing compatibility and connection fittings. The NSCDANN005PGUNV features a barbed port style versus the barbless configuration of the original. Package footprint differs (6-DIP versus 8-DIP with 0.524" spacing), necessitating PCB layout modification.
