Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91MCE1-S1 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration: DPST-NO/NC
• Current rating: 6A (AC) minimum
• Voltage rating: 120V (AC) minimum
• Switch function: On-Mom, Off-Mom operation

Mechanical Compatibility Requirements:

• Actuator type: Round (Pin Plunger)
• Mounting type: Chassis Mount
• Termination style: Cable Leads
• Ingress protection: IP67 minimum

Environmental & Regulatory Requirements:

• Operating temperature range: Must encompass or match -25°C to 85°C
• Electrical life: 500,000 cycles minimum
• Mechanical life: 5,000,000 cycles minimum
• RoHS compliance: Required

The NGCMA10AX01B satisfies all critical electrical, mechanical, and regulatory parameters, establishing it as a valid substitute despite differences in operating force characteristics and temperature range upper limit.

Parameter Comparison

Engineering Selection Recommendations

The NGCMA10AX01B is an active equivalent substitute for the obsolete 91MCE1-S1. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain identical electrical ratings, circuit configuration, and mechanical interface specifications.

Substitution Basis:

The NGCMA10AX01B meets all mandatory electrical compatibility criteria: 6A AC current rating, 120V AC voltage rating, DPST-NO/NC circuit configuration, and On-Mom/Off-Mom switch function. Mechanical compatibility is confirmed through matching actuator type (Round Pin Plunger), chassis mount configuration, cable lead termination, and IP67 ingress protection rating.

Both components satisfy regulatory requirements with RoHS compliance and equivalent electrical/mechanical life ratings (500,000 electrical cycles, 5,000,000 mechanical cycles).

Operational Consideration:

The NGCMA10AX01B operates within a reduced temperature range (-25°C to 75°C) compared to the 91MCE1-S1 (-25°C to 85°C). Applications requiring operation above 75°C require evaluation against actual thermal requirements.

The NGCMA10AX01B is available in active inventory status, ensuring supply chain availability for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the NGCMA10AX01B directly replace the 91MCE1-S1 in existing applications?

A: The NGCMA10AX01B is electrically and mechanically compatible with the 91MCE1-S1 for applications operating within the -25°C to 75°C temperature range. Applications requiring operation above 75°C require thermal analysis to confirm compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are product status (91MCE1-S1 is obsolete; NGCMA10AX01B is active) and maximum operating temperature (85°C versus 75°C). Operating force characteristics differ (816gf versus 1122gf), but both maintain identical electrical ratings and circuit configuration.

Q: Are both parts RoHS compliant?

A: Yes, both the 91MCE1-S1 and NGCMA10AX01B are RoHS compliant.

Q: What is the packaging difference?

A: The 91MCE1-S1 is supplied with cable leads as standard termination. The NGCMA10AX01B is available in bulk packaging with identical cable lead termination.

Q: Do these switches have identical electrical life ratings?

A: Yes, both components are rated for 500,000 electrical cycles and 5,000,000 mechanical cycles.

Q: Which part should be selected for new designs?

A: The NGCMA10AX01B should be selected for new designs due to its active product status and confirmed availability. The 91MCE1-S1 is obsolete and should not be specified for new applications.
