Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SX15GD2 is determined by the following critical parameters:

Pressure Specification Match: Operating pressure rating of 15PSI (103.42kPa) with vented gauge configuration is the primary functional requirement.

Output Interface Compatibility: Wheatstone Bridge output type ensures signal conditioning compatibility with existing measurement circuits.

Mechanical Interface Compatibility: Male 0.11" (2.67mm) tube port with barbless style and 6-DIP module packaging must align with board mount and pneumatic connection requirements.

Electrical Operating Range: Supply voltage, output voltage range, and temperature operating window must support existing system design parameters.

Accuracy and Performance: Measurement accuracy and maximum pressure rating determine suitability for application-specific performance requirements.

The SDX15G2-A meets these core substitution criteria while introducing enhanced specifications in accuracy and temperature compensation features.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SX15GD2 is obsolete, while the SDX15G2-A is active. Active product status ensures ongoing manufacturer support, availability, and compliance with current regulatory standards.

Compliance and Certification: Both parts maintain RoHS Compliant status and identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory equivalence for procurement and export purposes.

Functional Compatibility: The SDX15G2-A maintains identical operating pressure (15PSI), pressure type (vented gauge), output interface (Wheatstone Bridge), port configuration (male 0.11" tube, barbless), and thermal operating range (-40°C ~ 85°C). These parameters ensure functional substitution in existing applications.

Performance Enhancement: The SDX15G2-A provides improved accuracy (±0.25% versus ±0.5%) and includes temperature compensation features, delivering enhanced measurement stability across the operating temperature range.

Electrical Parameter Differences: The SDX15G2-A operates at 20V supply (versus 12V) and produces 0 mV ~ 90 mV output (versus 0 mV ~ 110 mV). These differences require circuit-level evaluation to confirm compatibility with existing signal conditioning and measurement electronics.

Pressure Rating Consideration: The SDX15G2-A maximum pressure rating is 30PSI (206.84kPa), compared to 45PSI for the SX15GD2. Applications requiring overpressure protection beyond 30PSI must retain the original specification or identify alternative parts.

Frequently Asked Questions (FAQ)

Q: Can the SDX15G2-A directly replace the SX15GD2 without circuit modifications?

A: The SDX15G2-A maintains identical operating pressure, pressure type, output interface type, port configuration, and thermal range. However, the supply voltage requirement (20V versus 12V) and output voltage range (0-90mV versus 0-110mV) differ. Circuit-level evaluation is required to confirm compatibility with existing power supply and signal conditioning circuits.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product status—SDX15G2-A is active versus SX15GD2 obsolete; (2) Supply voltage—20V versus 12V; (3) Output range—0-90mV versus 0-110mV; (4) Accuracy—±0.25% versus ±0.5%; (5) Maximum pressure—30PSI versus 45PSI; (6) Temperature compensation feature present in SDX15G2-A only.

Q: Are the mechanical interfaces identical?

A: Yes. Both parts feature male 0.11" (2.67mm) tube ports with barbless style, 6-DIP module packaging, and through-hole mounting configuration. Pneumatic and board-level connections are mechanically compatible.

Q: What is the significance of the temperature compensation feature in the SDX15G2-A?

A: Temperature compensation improves measurement accuracy stability across the -40°C to 85°C operating range. This feature reduces temperature-induced drift in the sensor output, resulting in the improved ±0.25% accuracy specification compared to the SX15GD2's ±0.5%.

Q: Does the lower maximum pressure rating of the SDX15G2-A affect substitution suitability?

A: The SDX15G2-A maximum pressure is 30PSI (206.84kPa) versus 45PSI for the SX15GD2. Applications operating near or exceeding 30PSI require verification that the substitute part's overpressure capability is adequate. For applications operating below 30PSI, this difference does not affect functional suitability.

Q: Are both parts RoHS compliant?

A: Yes. Both the SX15GD2 and SDX15G2-A are RoHS Compliant with identical ECCN and HTSUS classifications, ensuring regulatory equivalence for procurement and international trade purposes.
