Substitute Part Grouping Explanation
Substitution of the 91MCE16-P1B is determined by strict equivalence across the following critical parameters:
Electrical Equivalence: Circuit configuration (DPST-NO/NC), current rating (6A AC / 550mA DC), and voltage rating (120V AC / 125V DC) must be identical.
Mechanical Equivalence: Actuator type (side rotary roller), mounting configuration (chassis mount), and termination style (cable leads) must match.
Environmental Equivalence: Ingress protection rating (IP67), operating temperature range compatibility, and lifecycle ratings (electrical and mechanical cycles) must be maintained or exceeded.
Regulatory Equivalence: RoHS compliance status must be maintained.
The substitute part NGCMB10AX01A1B meets these criteria with identical electrical and mechanical specifications, though with minor variations in operating force, release force, and temperature range upper limit.

Engineering Selection Recommendations
The NGCMB10AX01A1B is a direct functional equivalent to the obsolete 91MCE16-P1B for applications requiring DPST snap action switching at 6A / 120V AC with side rotary roller actuation and chassis mount configuration.
Product Status Advantage: The NGCMB10AX01A1B maintains active product status with Honeywell, ensuring continued availability and support compared to the obsolete 91MCE16-P1B.
Regulatory Compliance: Both parts maintain RoHS compliance. The NGCMB10AX01A1B additionally carries REACH Unaffected status, providing expanded regulatory coverage.
Temperature Consideration: The substitute part operates to 75°C maximum, compared to 85°C for the original part. Applications requiring operation above 75°C require thermal analysis to confirm compatibility.
Mechanical Enhancement: The NGCMB10AX01A1B features stainless steel roller construction, providing enhanced corrosion resistance compared to the standard roller of the 91MCE16-P1B.
Frequently Asked Questions (FAQ)
Q: Can NGCMB10AX01A1B directly replace 91MCE16-P1B in existing designs?
A: Yes, for applications operating within the temperature range of -25°C to 75°C. The electrical ratings, circuit configuration, actuator type, and mounting configuration are identical. Applications requiring operation above 75°C require thermal evaluation.
Q: What is the primary reason for substitution?
A: The 91MCE16-P1B is classified as obsolete. The NGCMB10AX01A1B is an active equivalent part from the same manufacturer with identical functional specifications.
Q: Are there packaging differences between these parts?
A: The 91MCE16-P1B is supplied with cable leads (1m length specified). The NGCMB10AX01A1B is supplied in bulk packaging. Both use identical cable lead termination style.
Q: What are the differences in operating characteristics?
A: Release force differs (4.078gfm vs. 2.534gfm), and pretravel/differential travel/overtravel specifications vary slightly. Operating force remains identical at 18gfm. These differences do not affect functional equivalence for standard switching applications.
Q: Are both parts RoHS compliant?
A: Yes, both 91MCE16-P1B and NGCMB10AX01A1B are RoHS compliant. The substitute additionally carries REACH Unaffected status.
