Engineering Selection Recommendations

The NGCMA10AX01A1B serves as a direct functional equivalent to the obsolete 91MCE16-P1 based on identical electrical specifications, circuit topology, and mechanical configuration. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain RoHS Compliance with EAR99 ECCN classification.

The primary distinction is product lifecycle status: the 91MCE16-P1 is Obsolete while NGCMA10AX01A1B maintains Active status, ensuring continued availability and supply chain support. The NGCMA10AX01A1B features stainless steel roller construction and operates within a -25°C to 75°C temperature range, compared to the 91MCE16-P1 range of -25°C to 85°C. Applications requiring operation above 75°C require evaluation of the upper temperature limit differential.

Both parts deliver identical electrical performance: 6A AC at 120V, 550mA DC at 125V, with 500,000 electrical cycles and 5,000,000 mechanical cycles. Mechanical specifications including operating force, pretravel, differential travel, and overtravel parameters support equivalent functional performance in DPST momentary switching applications.

Frequently Asked Questions (FAQ)

Q: Can NGCMA10AX01A1B directly replace 91MCE16-P1 in existing designs?

A: Yes. Both components share identical circuit configuration (DPST-NO/NC), electrical ratings (6A AC/120V, 550mA DC/125V), actuator type (Side Rotary Roller), mounting configuration (Chassis Mount), termination style (Cable Leads), and ingress protection (IP67). Functional substitution is supported for applications operating within the -25°C to 75°C temperature range.

Q: What is the temperature range difference between these parts?

A: The 91MCE16-P1 operates from -25°C to 85°C, while NGCMA10AX01A1B operates from -25°C to 75°C. Applications requiring sustained operation above 75°C must evaluate this 10°C upper limit reduction.

Q: Are both parts RoHS Compliant?

A: Yes. Both the 91MCE16-P1 and NGCMA10AX01A1B are RoHS Compliant and carry EAR99 ECCN classification.

Q: What is the significance of the product status difference?

A: The 91MCE16-P1 is classified as Obsolete, indicating discontinued manufacturing and limited future availability. The NGCMA10AX01A1B maintains Active status, ensuring ongoing production, supply chain availability, and manufacturer support.

Q: Are the mechanical life specifications identical?

A: Yes. Both components are rated for 5,000,000 mechanical cycles and 500,000 electrical cycles, supporting equivalent durability in momentary switching applications.

Q: What packaging differences exist between these parts?

A: The 91MCE16-P1 is supplied with standard packaging, while NGCMA10AX01A1B is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.
