Key Parameters

Substitute Part Grouping Explanation

Substitution of the MG-15-A-MD-R is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Operating pressure specification: 15 PSI (103.42 kPa)
• Pressure type classification: Vented Gauge
• Output signal configuration: 4 mA ~ 20 mA with LCD Display
• Output transduction method: Wheatstone Bridge
• Supply voltage requirement: 12V
• Accuracy specification: ±0.5%
• Port connection standard: Male 1/4" (6.35 mm) NPT Threaded
• Temperature compensation capability: Required
• Operating temperature range: -10°C ~ 60°C
• Manufacturer: Amphenol SSI Technologies

The substitute part MG-15-A-M12-R maintains functional and electrical equivalence across all specified parameters while differing in connector interface style and product lifecycle status.

Engineering Selection Recommendations

Product Status Consideration: The MG-15-A-MD-R carries obsolete product status classification. The MG-15-A-M12-R is designated as active product status, indicating ongoing manufacturer support, availability assurance, and continued compliance with current regulatory standards.

Compliance and Certification: Both parts maintain RoHS compliance status. The MG-15-A-M12-R, as an active product, ensures alignment with current and future regulatory requirements without requiring design modification or system re-qualification.

Supply Chain Continuity: Current inventory levels support both immediate replacement requirements (MG-15-A-MD-R: 1032 units) and sustained long-term supply (MG-15-A-M12-R: 754 units). Selection of the active substitute part ensures uninterrupted component availability for future maintenance cycles and system expansion.

Functional Equivalence: Both parts originate from Amphenol SSI Technologies and share the same 15 PSI operating pressure specification and 4-20 mA LCD display output configuration, establishing direct functional compatibility within existing system architectures.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between MG-15-A-MD-R and MG-15-A-M12-R?

A: Both sensors maintain identical 15 PSI operating pressure specifications, Wheatstone Bridge output configuration, 4-20 mA signal with LCD display, and 12V supply voltage. The designation change from MD-R to M12-R reflects connector interface modification. The MG-15-A-M12-R carries active product status, ensuring ongoing manufacturer support and regulatory compliance.

Q: Can MG-15-A-M12-R directly replace MG-15-A-MD-R in existing installations?

A: Functional replacement is supported based on matching pressure range, output signal type, accuracy specification, and temperature compensation capability. Physical installation compatibility depends on connector interface requirements specific to your system configuration.

Q: What parameters must remain constant for substitution validity?

A: Operating pressure (15 PSI), pressure type (vented gauge), output configuration (4-20 mA with LCD), transduction method (Wheatstone Bridge), supply voltage (12V), accuracy (±0.5%), port connection standard (1/4" NPT male), temperature compensation, and operating temperature range (-10°C to 60°C) must all remain unchanged.

Q: Why is product status relevant to component selection?

A: Obsolete product status indicates discontinued manufacturer support and finite inventory availability. Active product status ensures sustained supply chain access, compliance with evolving regulatory standards, and manufacturer technical support for troubleshooting and integration.

Q: Are there inventory considerations for long-term system planning?

A: Current stock levels for MG-15-A-MD-R (1032 units) support immediate replacement needs. For systems requiring extended operational life or multiple replacement cycles, MG-15-A-M12-R (754 units in stock, active status) provides sustained availability assurance.
