Key Parameters

Substitute Part Grouping Explanation

Substitution of the MG-1000-A-MD-R is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure of 1000 PSI and maximum pressure rating of 3000 PSI must be maintained.

Output Characteristics: Wheatstone Bridge output type with 4-20 mA signal range and LCD display functionality must be preserved.

Electrical Requirements: 12V supply voltage specification must be matched.

Mechanical Interface: Male 1/4" NPT threaded port configuration must remain consistent.

Environmental Performance: Temperature compensation feature and operating range of -10°C to 60°C must be retained.

Pressure Classification: Vented gauge pressure type must be maintained.

Accuracy Standard: ±0.25% accuracy specification must be met or exceeded.

Compliance: RoHS compliance status must be maintained.

The substitute part MG-1000-A-MD-R is identified based on manufacturer designation within the Amphenol SSI Technologies product line, maintaining functional and mechanical equivalence while transitioning from obsolete to active product status.

Parameter Comparison

Engineering Selection Recommendations

The MG-1000-A-M12-R serves as the direct functional equivalent to the obsolete MG-1000-A-MD-R. Both components maintain identical electrical, mechanical, and performance specifications across all critical parameters including pressure rating, output characteristics, accuracy, and operating environment.

Product Status Consideration: The MG-1000-A-M12-R holds active product status with confirmed inventory availability (1084 units), ensuring long-term supply chain reliability compared to the obsolete MG-1000-A-MD-R.

Compliance Alignment: Both parts maintain RoHS compliance certification, satisfying regulatory requirements for industrial automation applications.

Packaging Difference: The primary distinction between the two parts is packaging configuration. The MG-1000-A-MD-R is supplied in Module Box with Display packaging, while the MG-1000-A-M12-R is supplied in Bulk packaging. This packaging difference does not affect functional performance or mechanical compatibility.

Application Continuity: Direct substitution of MG-1000-A-M12-R for MG-1000-A-MD-R maintains system performance without modification to pressure measurement circuits, signal conditioning, or mechanical mounting interfaces.
