Frequently Asked Questions (FAQ)

Q: Can the NGCMA30AX01A1B directly replace the 91MCE16-P3 in existing applications?

A: The NGCMA30AX01A1B is electrically and mechanically equivalent to the 91MCE16-P3 across all critical parameters: DPST-NO/NC circuit, 6A AC / 550mA DC current rating, 120V AC / 125V DC voltage rating, side rotary roller actuator, chassis mount configuration, cable lead termination, and IP67 ingress protection. Direct substitution is supported for applications operating within the -25°C to 75°C temperature range.

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

A: The 91MCE16-P3 operates from -25°C to 85°C, while the NGCMA30AX01A1B operates from -25°C to 75°C. The substitute part has a 10°C lower upper temperature limit. Applications requiring operation above 75°C must confirm compatibility with the substitute's thermal specifications.

Q: Are both parts RoHS Compliant?

A: Yes, both the 91MCE16-P3 and NGCMA30AX01A1B are RoHS Compliant, meeting environmental and regulatory requirements for lead-free manufacturing.

Q: What is the significance of the stainless steel roller feature on the NGCMA30AX01A1B?

A: The stainless steel roller on the NGCMA30AX01A1B provides enhanced corrosion resistance and durability compared to standard roller materials. This feature does not affect electrical or mechanical equivalence but may extend component life in corrosive environments.

Q: Do both parts have identical electrical life ratings?

A: Yes, both the 91MCE16-P3 and NGCMA30AX01A1B are rated for 500,000 electrical cycles and 5,000,000 mechanical cycles, providing equivalent operational longevity.

Q: Why is the 91MCE16-P3 classified as obsolete?

A: The 91MCE16-P3 is obsolete, indicating it is no longer in active production. The NGCMA30AX01A1B is the active equivalent part from Honeywell Sensing and Productivity Solutions, ensuring continued supply chain availability.
