Key Parameters

Substitute Part Grouping Explanation

Substitution of the MG-100-A-MD-R is based on the following critical parameters that must remain consistent across equivalent models:

Functional Parameters:

• Operating pressure rating of 100 PSI
• Wheatstone Bridge output configuration
• 4 mA ~ 20 mA analog signal output with LCD display capability
• Accuracy specification of ±0.25%
• 12V supply voltage requirement

Physical Parameters:

• Male 1/4" NPT threaded port connection
• Vented gauge pressure type
• Temperature compensation feature
• Operating temperature range of -10°C ~ 60°C

Compliance Parameters:

• RoHS compliance status
• Amphenol SSI Technologies manufacturer designation

The substitute part MG-100-A-M12-R maintains all functional and physical parameters while transitioning from an obsolete product status to an active production status. The primary difference is the connector interface designation (M12 versus MD), which represents a modernization of the connection standard while preserving electrical and mechanical compatibility within the specified parameter envelope.

Engineering Selection Recommendations

The MG-100-A-M12-R is the designated substitute for the obsolete MG-100-A-MD-R based on the following engineering criteria:

Product Status Alignment: The MG-100-A-M12-R maintains active production status, ensuring long-term component availability and supply chain continuity. The MG-100-A-MD-R, classified as obsolete, presents procurement risk for new system designs and ongoing field maintenance.

Functional Equivalence: Both parts maintain identical electrical specifications including the 100 PSI operating pressure, Wheatstone Bridge output configuration, 4 mA ~ 20 mA signal output, ±0.25% accuracy, and 12V supply voltage. This equivalence ensures direct functional replacement without system redesign.

Compliance Certification: The MG-100-A-MD-R is confirmed RoHS compliant. Selection of the MG-100-A-M12-R as the active substitute maintains compliance with regulatory requirements for industrial automation applications.

Inventory Availability: Current stock levels indicate 677 units of MG-100-A-M12-R available, supporting immediate procurement for production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the MG-100-A-M12-R directly replace the MG-100-A-MD-R in existing installations?

A: Yes. Both parts maintain identical operating pressure (100 PSI), output type (Wheatstone Bridge), signal output (4 mA ~ 20 mA with LCD display), accuracy (±0.25%), supply voltage (12V), and temperature compensation features. The primary difference is the connector interface designation, which represents a modernization of the connection standard.

Q: What is the significance of the MD versus M12 designation in the part numbers?

A: The MD and M12 designations refer to different connector interface standards. Both maintain the same threaded port configuration (Male 1/4" NPT) and electrical compatibility. The M12 designation represents the current production standard for this sensor family.

Q: Are there any compatibility considerations for the port connection?

A: Both parts feature Male 1/4" NPT threaded ports for vented gauge pressure applications. Port compatibility remains unchanged between the two models.

Q: Why is the MG-100-A-MD-R classified as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation of a model line in favor of updated designs. The MG-100-A-M12-R represents the active equivalent within the current product portfolio.

Q: What is the operating temperature range for both parts?

A: Both the MG-100-A-MD-R and MG-100-A-M12-R operate within the temperature range of -10°C to 60°C with temperature compensation features integrated into the sensor design.

Q: Are both parts RoHS compliant?

A: The MG-100-A-MD-R is confirmed RoHS compliant. RoHS compliance status for the MG-100-A-M12-R is not specified in the provided technical documentation.
