Substitute Part Grouping Explanation

Substitution of the obsolete 91MCE28-PQ is based on strict electrical and mechanical parameter matching within the Honeywell snap action switch product family. The substitute part NGCMA00NX01P maintains functional equivalence through identical specifications in the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: DPST-NO/NC
• Switch function: On-Mom, Off-Mom
• Current rating: 6A (AC), 550mA (DC)
• Voltage rating: 120V (AC), 125V (DC)
• Electrical life: 500,000 cycles

Mechanical Equivalence Criteria:

• Actuator type: Roller Plunger
• Mounting type: Panel Mount
• Termination style: Connector
• Ingress protection: IP67
• Operating force: 1122gf
• Mechanical life: 5,000,000 cycles

Compliance Equivalence:

• RoHS Compliant status
• Moisture Sensitivity Level 1
• ECCN and HTSUS classifications maintained

The substitute part operates within the same environmental temperature range (-25°C to 75°C for NGCMA00NX01P versus -25°C to 85°C for 91MCE28-PQ) and maintains connector-based termination for direct integration into existing panel mount applications.

Parameter Comparison

Engineering Selection Recommendations

The NGCMA00NX01P is the direct functional equivalent for the obsolete 91MCE28-PQ based on identical electrical ratings, mechanical specifications, and environmental protection classification. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain RoHS compliance with MSL 1 rating.

Selection Basis:

The substitute part NGCMA00NX01P is Active status, ensuring ongoing availability and supply chain continuity. The component maintains all critical electrical parameters: 6A AC current rating, 120V AC voltage rating, DPST-NO/NC circuit configuration, and 500,000 cycle electrical life specification.

Mechanical compatibility is confirmed through identical actuator type (Roller Plunger), mounting configuration (Panel Mount), connector-based termination, and IP67 ingress protection rating. Operating force specification of 1122gf remains constant between both parts.

The operating temperature range of the substitute part extends to 75°C maximum, which is 10°C lower than the original 91MCE28-PQ specification of 85°C. Applications requiring operation above 75°C require thermal analysis to confirm compatibility.

Both parts carry identical ECCN (EAR99) and HTSUS classifications, supporting regulatory and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can NGCMA00NX01P directly replace 91MCE28-PQ in existing panel mount installations?

A: Yes. Both components share identical mounting type (Panel Mount), termination style (Connector), and mechanical dimensions based on the provided specifications. Physical installation compatibility is confirmed through matching connector-based termination and panel mount configuration.

Q: What is the significance of the operating temperature range difference?

A: The 91MCE28-PQ operates from -25°C to 85°C, while NGCMA00NX01P operates from -25°C to 75°C. Applications operating continuously above 75°C require verification that the substitute part meets thermal requirements. The lower temperature limit (-25°C) is identical for both parts.
