Key Parameters

Substitute Part Grouping Explanation

Substitution of the MG-500-A-MD-R is determined by strict alignment of the following critical parameters:

Pressure Specifications: Operating pressure of 500 PSI and maximum pressure rating of 1500 PSI must be maintained to ensure sensor accuracy and safety margins within the original system design.

Output Characteristics: The combination of Wheatstone Bridge output with 4-20 mA analog signal and LCD display functionality defines the electrical interface requirements for system integration.

Mechanical Interface: Male 1/4" NPT threaded port configuration must be preserved to ensure direct installation compatibility without adapter requirements.

Environmental Performance: Operating temperature range of -10°C to +60°C and temperature compensation capability must be maintained for consistent measurement accuracy across industrial operating conditions.

Electrical Supply: 12V supply voltage requirement must be matched to ensure compatibility with existing power distribution infrastructure.

Compliance Standards: RoHS compliance and MSL 1 rating must be maintained for regulatory and reliability requirements.

The substitute part MG-500-A-M12-R from Amphenol SSI Technologies meets all critical parameter requirements while offering active product status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MG-500-A-MD-R carries obsolete product status, indicating discontinued manufacturing and limited long-term availability. The MG-500-A-M12-R maintains active product status, ensuring continued manufacturing support, technical documentation availability, and supply chain reliability for future procurement requirements.

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL 1 ratings, ensuring regulatory requirements and moisture sensitivity handling procedures remain unchanged during substitution.

Functional Equivalence: Complete parameter alignment across pressure specifications, output characteristics, electrical supply, mechanical interface, and environmental performance ratings confirms direct functional equivalence between the main part and substitute part.

Supply Chain Continuity: Selection of the MG-500-A-M12-R provides immediate supply chain continuity while maintaining identical system performance characteristics, eliminating the need for system redesign or recalibration.

Frequently Asked Questions (FAQ)

Q: Can the MG-500-A-M12-R be directly installed in place of the MG-500-A-MD-R without modifications?

A: Yes. Both sensors share identical mechanical interface specifications (Male 1/4" NPT threaded port), electrical supply requirements (12V), and output characteristics (Wheatstone Bridge with 4-20 mA and LCD display). Direct installation is supported without mechanical or electrical modifications.

Q: Are the pressure measurement ranges identical between these two sensors?

A: Yes. Both sensors operate at 500 PSI with a maximum pressure rating of 1500 PSI. Accuracy specifications (±0.25%) and temperature compensation functionality are identical, ensuring measurement consistency across the operating range.

Q: What is the primary advantage of substituting to the MG-500-A-M12-R?

A: The MG-500-A-M12-R maintains active product status, ensuring continued manufacturing, technical support, and supply availability. The MG-500-A-MD-R is obsolete, presenting long-term supply chain risk for maintenance and replacement requirements.

Q: Do environmental operating conditions differ between these sensors?

A: No. Both sensors operate across the identical temperature range of -10°C to +60°C with temperature compensation enabled. Environmental performance and reliability characteristics remain unchanged.

Q: Are there any compliance or certification differences?

A: No. Both sensors maintain RoHS compliance and MSL 1 moisture sensitivity ratings. Regulatory and handling requirements remain identical.

Q: What inventory status should be considered for procurement planning?

A: Current inventory shows 697 units of MG-500-A-MD-R and 702 units of MG-500-A-M12-R available. However, the obsolete status of MG-500-A-MD-R indicates limited future availability, while active status of MG-500-A-M12-R supports ongoing procurement capability.
