Key Parameters

Substitute Part Grouping Explanation

Substitution of the MG-3000-A-MD-R is determined by the following critical parameters that must remain consistent:

Pressure Specifications: Operating pressure of 3000 PSI and maximum pressure rating of 9000 PSI establish the pressure measurement capability.

Output Characteristics: Wheatstone Bridge output with 4-20 mA signal and LCD display functionality define the signal transmission and display requirements.

Electrical Requirements: 12V supply voltage and ±0.25% accuracy specify the power and measurement precision.

Mechanical Interface: Male 1/4" NPT threaded port size determines physical installation compatibility.

Environmental Performance: Temperature compensation and -10°C to 60°C operating range establish thermal stability requirements.

Compliance: RoHS compliance and MSL Level 1 rating confirm regulatory and moisture handling standards.

The MG-3000-A-M12-R is identified as a manufacturer-recommended substitute based on these core parameters.

Parameter Comparison

Engineering Selection Recommendations

The MG-3000-A-M12-R is the manufacturer-recommended substitute for the obsolete MG-3000-A-MD-R. Both parts are manufactured by Amphenol SSI Technologies and maintain identical electrical, mechanical, and performance specifications across all critical parameters.

The primary distinction between these parts is product status and packaging configuration. The MG-3000-A-MD-R is classified as Obsolete, while the MG-3000-A-M12-R maintains Active status, ensuring continued manufacturing support and availability.

Both parts maintain RoHS compliance and equivalent moisture sensitivity ratings, confirming regulatory alignment and environmental handling consistency.

For applications currently specified with MG-3000-A-MD-R, the MG-3000-A-M12-R provides direct functional equivalence with the advantage of active product support and ongoing availability.

Frequently Asked Questions (FAQ)

Q: Can the MG-3000-A-M12-R directly replace the MG-3000-A-MD-R in existing installations?

A: Yes. Both parts share identical pressure ratings (3000 PSI operating, 9000 PSI maximum), output characteristics (Wheatstone Bridge with 4-20 mA and LCD display), supply voltage (12V), port configuration (Male 1/4" NPT), and accuracy (±0.25%). The mechanical and electrical interfaces are equivalent.

Q: What is the difference between the MG-3000-A-MD-R and MG-3000-A-M12-R?

A: The primary differences are product status and packaging. The MG-3000-A-MD-R is Obsolete with Module Box packaging, while the MG-3000-A-M12-R is Active with Bulk packaging. All functional specifications remain identical.

Q: Why is the MG-3000-A-MD-R listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production of this specific model variant. The MG-3000-A-M12-R represents the current active equivalent from Amphenol SSI Technologies.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain RoHS compliance and MSL Level 1 rating, confirming equivalent regulatory and environmental handling standards.

Q: What packaging differences exist between these substitutes?

A: The MG-3000-A-MD-R ships in Module Box with Display packaging, while the MG-3000-A-M12-R is supplied in Bulk packaging. This distinction affects logistics and storage but does not impact functional performance or installation compatibility.

Q: Is the temperature compensation feature present in both parts?

A: Yes. Both the MG-3000-A-MD-R and MG-3000-A-M12-R include temperature compensation and operate across the identical -10°C to 60°C temperature range.
