Key Parameters

Substitute Part Grouping Explanation

Substitution of the 91MCE2-P1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Circuit configuration (DPST-NO/NC), switch function (On-Mom, Off-Mom), current rating (6A AC / 550mA DC), and voltage rating (120V AC / 125V DC) must match exactly.

Mechanical Equivalence: Actuator type (Roller Plunger), mounting type (Chassis Mount), and termination style (Cable Leads) must be identical.

Environmental Equivalence: Ingress protection rating (IP67), operating temperature range compatibility, and lifecycle ratings (electrical and mechanical cycles) must be maintained or exceeded.

Compliance Equivalence: RoHS compliance status must be maintained.

The NGCMA10AX01C meets all these criteria as an active product alternative from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The NGCMA10AX01C from Honeywell Sensing and Productivity Solutions is the qualified substitute for the obsolete 91MCE2-P1. Both components share identical electrical ratings, mechanical configurations, and environmental protection specifications. The NGCMA10AX01C maintains RoHS compliance and equivalent lifecycle performance.

The primary consideration is the operating temperature range: the 91MCE2-P1 operates to 85°C while the NGCMA10AX01C operates to 75°C. Applications requiring operation above 75°C require evaluation against actual system thermal requirements.

The NGCMA10AX01C is currently in active production status with documented inventory availability, ensuring supply chain continuity for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the NGCMA10AX01C directly replace the 91MCE2-P1 in existing assemblies?

A: Yes, the NGCMA10AX01C provides direct functional equivalence across all critical electrical and mechanical parameters. Both components feature identical circuit configuration (DPST-NO/NC), current and voltage ratings, actuator type (Roller Plunger), mounting configuration (Chassis Mount), and termination style (Cable Leads). Physical verification of mounting dimensions and cable lead routing is required for specific assembly applications.

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

A: The 91MCE2-P1 operates from -25°C to 85°C, while the NGCMA10AX01C operates from -25°C to 75°C. This 10°C difference in maximum operating temperature affects applications in high-temperature environments. Systems operating consistently above 75°C require confirmation that the NGCMA10AX01C meets thermal requirements.

Q: Are both parts RoHS compliant?

A: Yes, both the 91MCE2-P1 and NGCMA10AX01C are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What is the difference between the 91MCE series and NGC series?

A: The 91MCE2-P1 belongs to the obsolete 91MCE series, while the NGCMA10AX01C belongs to the active NGC series. Both are manufactured by Honeywell Sensing and Productivity Solutions and share equivalent electrical and mechanical specifications. The NGC series represents the current production line for this switch category.

Q: Are there packaging differences between these parts?

A: The 91MCE2-P1 is specified with cable length of 1m. The NGCMA10AX01C packaging is listed as Bulk. Specific cable length and packaging configuration should be confirmed with the supplier for your application requirements.

Q: What are the mechanical life and electrical life specifications?

A: Both components are rated for 500,000 electrical cycles and 5,000,000 mechanical cycles, providing equivalent durability and reliability for snap action switch applications.
