SX05GD2 Equivalent & Substitute Parts Reference

Part Overview

The SX05GD2 is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement. This 6-DIP module sensor operates at 5PSI (34.47kPa) with a Wheatstone Bridge output of 0 mV to 75 mV at 5V supply voltage.

The SX05GD2 is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing system maintenance, design updates, and procurement continuity. Active alternative models with compatible electrical and mechanical specifications are available from the same manufacturer.

Substitute Part Grouping Explanation

Substitution of the SX05GD2 is based on the following critical parameters that must remain compatible:

Electrical Compatibility:

Operating pressure: 5PSI (34.47kPa)
Pressure type: Vented Gauge
Output type: Wheatstone Bridge
Output range: 0 mV ~ 75 mV (5V)
Operating temperature range: -40°C ~ 85°C
Maximum pressure rating: 20PSI (137.9kPa)

Mechanical Compatibility:

Mounting type: Through Hole
Port configuration: Male tube connection
Applications: Board Mount

The NSCDANN005PGUNV meets these core electrical and mechanical requirements. While differences exist in package configuration (8-DIP versus 6-DIP), port size (0.19" versus 0.11"), accuracy specification (±0.25% versus ±0.5%), and supply voltage range (1.5V ~ 12V versus 12V), the substitute maintains functional equivalence for the specified pressure measurement application.

Engineering Selection Recommendations

The NSCDANN005PGUNV is the designated substitute for the obsolete SX05GD2. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain RoHS compliance.

Status Consideration: The SX05GD2 is obsolete, while the NSCDANN005PGUNV is active production. For new designs or system updates, the NSCDANN005PGUNV is the appropriate selection.

Compliance: Both parts are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory consistency.

Functional Equivalence: Both sensors deliver identical pressure measurement capability at 5PSI with Wheatstone Bridge output in the 0 mV to 75 mV range across the -40°C to 85°C operating window.

Design Integration Factors: Implementation of the NSCDANN005PGUNV requires evaluation of:

PCB layout accommodation for 8-DIP package versus 6-DIP
Tubing interface compatibility with 0.19" (4.93mm) barbed port versus 0.11" (2.67mm) barbless port
Supply voltage circuit capability for the 1.5V ~ 12V range

Frequently Asked Questions (FAQ)

Q: Can the NSCDANN005PGUNV directly replace the SX05GD2 without circuit modification?

A: Electrical substitution is direct for supply voltages at 12V. The NSCDANN005PGUNV accepts 1.5V ~ 12V, providing broader supply flexibility. However, physical integration requires PCB layout changes due to 8-DIP versus 6-DIP package differences and port size variation (0.19" versus 0.11" tube).

Q: What is the significance of the port size difference between these sensors?

A: The SX05GD2 uses a 0.11" (2.67mm) barbless male tube port, while the NSCDANN005PGUNV uses a 0.19" (4.93mm) barbed male tube port. Tubing compatibility and connection method differ. Appropriate tubing and fittings must be selected for the 0.19" barbed configuration.

Q: Does the accuracy difference (±0.5% versus ±0.25%) affect substitution?

A: The NSCDANN005PGUNV provides improved accuracy specification. For applications requiring ±0.5% accuracy, the substitute exceeds the original specification. For applications with tighter accuracy requirements, the substitute is suitable.

Q: Are both sensors suitable for the same temperature range?

A: Yes. Both the SX05GD2 and NSCDANN005PGUNV operate across -40°C to 85°C, ensuring thermal compatibility.

Q: What is the inventory status for these components?

A: The SX05GD2 has 1015 pieces in stock (obsolete status). The NSCDANN005PGUNV has 1045 pieces in stock (active production status).
