Key Parameters

Substitute Part Grouping Explanation

Substitution of the 91MCE16-P2B is based on electrical and mechanical parameter equivalence within the Honeywell snap action switch product line. The primary substitute, NGCMB20AX01A1B, maintains functional compatibility through identical circuit configuration (DPST-NO/NC), switch function (On-Mom, Off-Mom), current ratings (6A AC / 550mA DC), and voltage ratings (120V AC / 125V DC). Both parts feature side rotary roller actuators, chassis mounting, cable leads termination, and IP67 ingress protection.

The substitution is valid based on the following key parameters:

• Identical circuit topology and switching function
• Matching current and voltage electrical ratings
• Equivalent actuator type and mounting configuration
• Identical termination style and environmental protection rating
• Compliance with RoHS requirements
• Active product status of the substitute part

Parameter Comparison

Engineering Selection Recommendations

The NGCMB20AX01A1B is a direct functional equivalent to the obsolete 91MCE16-P2B for applications requiring DPST snap action switching at 6A AC / 120V. Both parts are manufactured by Honeywell Sensing and Productivity Solutions and maintain identical electrical ratings, circuit configuration, and mechanical specifications.

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts carry RoHS compliance certification and are classified under identical HTSUS and ECCN codes, supporting regulatory and export compliance requirements.

One operational consideration exists: the substitute part (NGCMB20AX01A1B) operates within a temperature range of -25°C to 75°C, compared to the original part's -25°C to 85°C range. Applications requiring operation above 75°C require evaluation against the substitute's thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can NGCMB20AX01A1B directly replace 91MCE16-P2B in existing installations?

A: Yes. Both parts share identical circuit configuration (DPST-NO/NC), electrical ratings (6A AC / 120V AC, 550mA DC / 125V DC), actuator type (side rotary roller), mounting method (chassis mount), and termination style (cable leads). Physical and functional compatibility is established.

Q: What is the primary difference between these two parts?

A: The 91MCE16-P2B is obsolete, while NGCMB20AX01A1B is an active product. The substitute operates within a narrower temperature range (-25°C to 75°C versus -25°C to 85°C). Release force specifications also differ (2.534gfm versus 4.078gfm).

Q: Are both parts RoHS compliant?

A: Yes. Both the 91MCE16-P2B and NGCMB20AX01A1B are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.9055) classifications.

Q: What packaging is available for the substitute part?

A: The NGCMB20AX01A1B is supplied in bulk packaging, whereas the original part number does not specify packaging format in available documentation.

Q: Are the mechanical life specifications identical?

A: Yes. Both parts are rated for 5,000,000 mechanical cycles and 500,000 electrical cycles, providing equivalent operational longevity.

Q: Should temperature range differences affect my selection?

A: If your application operates continuously above 75°C, the substitute part's upper temperature limit requires evaluation. For applications within -25°C to 75°C, the substitute is fully compatible.
