91MCE3-P1B Equivalent & Substitute Parts

Part Overview

The 91MCE3-P1B is a snap action DPST switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis-mounted switch features a cross roller plunger actuator, rated for 6A AC at 120V and 550mA DC at 125V, with IP67 ingress protection. The part is classified as obsolete, necessitating identification of active equivalent models to maintain supply chain continuity for applications requiring DPST-NO/NC switching functionality with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 91MCE3-P1B is based on strict equivalence of the following critical parameters:

Electrical Equivalence:

• Circuit configuration: DPST-NO/NC
• Current rating: 6A AC / 550mA DC
• Voltage rating: 120V AC / 125V DC
• Switch function: On-Mom, Off-Mom

Mechanical Equivalence:

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

Environmental & Compliance:

• Operating temperature range compatibility
• Electrical and mechanical life ratings
• RoHS compliance status

The NGCMB10AX01L meets all critical electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Honeywell Sensing and Productivity Solutions and share identical circuit configuration, current/voltage ratings, actuator type, and mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

The NGCMB10AX01L is the direct substitute for the obsolete 91MCE3-P1B based on the following engineering criteria:

Electrical Compatibility: Both parts are rated identically for 6A AC at 120V and 550mA DC at 125V with DPST-NO/NC circuit configuration. Switching function and electrical life specifications are equivalent.

Mechanical Compatibility: Both parts feature cross roller plunger actuators, chassis mount configuration, cable lead termination, and IP67 ingress protection. Operating force is identical at 1122gf.

Compliance Status: Both parts are RoHS compliant and manufactured by the same supplier. The NGCMB10AX01L is active product status, ensuring ongoing availability and supply chain support.

Parameter Variations: The NGCMB10AX01L exhibits minor variations in pretravel (0.083" vs 0.071"), differential travel (0.047" vs 0.031"), overtravel (0.193" vs 0.125"), and maximum operating temperature (75°C vs 85°C). These variations remain within acceptable tolerances for DPST snap action switch applications and do not affect core switching performance or electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can NGCMB10AX01L directly replace 91MCE3-P1B in existing applications?

A: Yes. Both parts share identical electrical ratings (6A AC/120V, 550mA DC/125V), circuit configuration (DPST-NO/NC), actuator type (cross roller plunger), mounting type (chassis mount), and termination style (cable leads). The substitute is suitable for direct replacement in applications where the original part is no longer available.

Q: What are the differences between these two parts?

A: The primary differences are product status (91MCE3-P1B is obsolete; NGCMB10AX01L is active) and minor mechanical parameter variations. The NGCMB10AX01L has slightly larger pretravel, differential travel, and overtravel values, and a lower maximum operating temperature (75°C vs 85°C). These differences do not affect electrical switching performance or compatibility with standard DPST applications.

Q: Are there packaging differences between these parts?

A: Yes. The 91MCE3-P1B is supplied with cable leads as standard termination. The NGCMB10AX01L is available in bulk packaging. Both parts maintain identical functional specifications and mounting requirements.

Q: What is the operating temperature consideration for substitution?

A: The 91MCE3-P1B operates from -25°C to 85°C, while the NGCMB10AX01L operates from -25°C to 75°C. Applications requiring operation above 75°C should evaluate the lower maximum temperature of the substitute part against specific system requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 91MCE3-P1B and NGCMB10AX01L are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the 91MCE3-P1B classified as obsolete?

A: The 91MCE3-P1B is obsolete product status, indicating it is no longer in active production. The NGCMB10AX01L represents the active equivalent from Honeywell Sensing and Productivity Solutions for continued supply and support.
