Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MG-200-A-MD-R is classified as obsolete, while the MG-200-A-M12-R is classified as active. Selection of the active product status part supports long-term supply chain continuity and manufacturing support from Amphenol SSI Technologies.

Compliance Consideration: The MG-200-A-MD-R carries RoHS compliance certification. Substitute part selection should verify equivalent RoHS compliance status to maintain regulatory alignment in industrial automation applications.

Inventory Availability: The MG-200-A-MD-R maintains 1162 pieces in current stock. The MG-200-A-M12-R maintains 1039 pieces in current stock, providing alternative procurement channels for equivalent functionality.

Connector Interface Difference: The primary distinction between these parts is the connector interface designation (MD versus M12 suffix). This difference reflects the physical connection method and must be evaluated against existing system integration requirements and installation specifications.

Frequently Asked Questions (FAQ)

Q: What determines if MG-200-A-M12-R can substitute for MG-200-A-MD-R?

A: Substitution is valid when the operating pressure (200 PSI), output signal type (Wheatstone Bridge with 4-20 mA), display capability (LCD), accuracy (±0.25%), supply voltage (12V), and operating temperature range (-10°C to 60°C) are equivalent. Both parts meet these criteria.

Q: What is the primary difference between these two part numbers?

A: The suffix designation (MD versus M12) indicates a difference in the connector interface style. The MD variant uses a module box with display configuration, while the M12 designation indicates an M12 connector interface. This affects physical installation and integration methodology.

Q: Why is the MG-200-A-MD-R listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The MG-200-A-M12-R, classified as active, represents the current production equivalent from Amphenol SSI Technologies for this functional specification.

Q: Are there any compatibility concerns when substituting these parts?

A: Compatibility depends on the existing system's connector interface requirements and mechanical mounting specifications. The electrical and functional parameters are equivalent; however, the physical connection method differs and must align with system design specifications.

Q: What is the pressure measurement type for both sensors?

A: Both sensors operate as vented gauge pressure transducers, measuring gauge pressure relative to atmospheric pressure with a 200 PSI operating range and 600 PSI maximum pressure rating.

Q: Do both parts include temperature compensation?

A: The MG-200-A-MD-R includes temperature compensation as a specified feature. Equivalent temperature compensation status for the MG-200-A-M12-R should be verified through detailed technical documentation.
