Substitute Part Grouping Explanation

Substitution of the 91MCE28-P1 is based on strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration: DPST-NO/NC
• Current rating: 6A (AC) and 550mA (DC)
• Voltage rating: 120V (AC) and 125V (DC)

Mechanical Equivalence Requirements:

• Actuator type: Roller Plunger
• Mounting type: Panel Mount
• Termination style: Cable Leads
• Ingress protection: IP67

Lifecycle Equivalence Requirements:

• Electrical life: 500,000 cycles minimum
• Mechanical life: 5,000,000 cycles minimum
• RoHS compliance status

The Honeywell NGCMA10AX01P satisfies all mandatory electrical, mechanical, and lifecycle parameters. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain identical core functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The NGCMA10AX01P is the direct functional equivalent for the obsolete 91MCE28-P1. Selection of this substitute is supported by the following factors:

Electrical Compatibility: Both components maintain identical current and voltage ratings across AC and DC operating conditions, ensuring direct functional replacement in existing circuit designs.

Mechanical Compatibility: Identical actuator type, mounting configuration, and termination style enable direct mechanical substitution without enclosure or wiring modifications.

Lifecycle Compliance: Both components meet the same electrical and mechanical cycle ratings, supporting equivalent operational longevity in production environments.

Regulatory Compliance: The NGCMA10AX01P maintains RoHS compliance status, meeting current environmental and regulatory requirements for component procurement.

Active Production Status: The NGCMA10AX01P is in active production, ensuring long-term availability and supply chain continuity compared to the obsolete 91MCE28-P1.

Parameter Variations: The NGCMA10AX01P exhibits minor variations in pretravel, differential travel, overtravel, and maximum operating temperature. These variations remain within acceptable tolerances for standard industrial switching applications. The reduced upper temperature limit (75°C versus 85°C) should be evaluated only in applications requiring sustained operation above 75°C.

Frequently Asked Questions (FAQ)

Q: Can the NGCMA10AX01P directly replace the 91MCE28-P1 in existing installations?

A: Yes. Both components share identical electrical ratings (6A at 120V AC), circuit configuration (DPST-NO/NC), actuator type (roller plunger), mounting type (panel mount), and termination style (cable leads). Direct substitution is supported without circuit or mechanical modifications.

Q: What are the differences between these two components?

A: The primary differences are product status and minor mechanical specifications. The NGCMA10AX01P is in active production, while the 91MCE28-P1 is obsolete. The NGCMA10AX01P exhibits slightly larger pretravel (0.083" versus 0.071"), differential travel (0.047" versus 0.031"), and overtravel (0.193" versus 0.125") values. The maximum operating temperature is 75°C for the NGCMA10AX01P compared to 85°C for the 91MCE28-P1.

Q: Are there any applications where the NGCMA10AX01P cannot replace the 91MCE28-P1?

A: Applications requiring sustained operation above 75°C should be evaluated individually. The mechanical travel variations are negligible for standard industrial switching applications but should be confirmed for precision positioning or timing-critical circuits.

Q: What is the cable lead configuration for both components?

A: Both components feature cable leads as the termination style. Specific lead gauge, length, and connector specifications should be verified against the detailed component datasheets for your application requirements.

Q: Are both components RoHS compliant?

A: Yes. Both the 91MCE28-P1 and NGCMA10AX01P are RoHS compliant, meeting current environmental and regulatory standards for component procurement and use.

Q: What is the availability status of these components?

A: The 91MCE28-P1 is obsolete with limited remaining inventory (1014 pieces). The NGCMA10AX01P is in active production with current inventory of 1006 pieces. For new designs and long-term supply requirements, the NGCMA10AX01P is the recommended selection.
