Key Parameters

Substitute Part Grouping Explanation

Substitution of the 91MCE16-P5 is based on electrical and mechanical parameter equivalence within the Honeywell product portfolio. The primary substitute, NGCMA50AX01A1B, maintains functional compatibility through identical circuit configuration (DPST-NO/NC), switch function (On-Mom, Off-Mom), current ratings (6A AC / 550mA DC), voltage ratings (120V AC / 125V DC), actuator type (side rotary roller), mounting type (chassis mount), termination style (cable leads), and ingress protection rating (IP67).

Key parameters determining substitution eligibility include:

• Circuit configuration and switch function
• Current and voltage ratings
• Actuator type and mounting interface
• Termination style and connector compatibility
• Environmental protection rating (IP67)
• Operating temperature range compatibility
• Electrical and mechanical life cycle ratings
• RoHS compliance and MSL classification

The NGCMA50AX01A1B represents an active product within the NGC series, providing continued availability and manufacturer support compared to the obsolete 91MCE16-P5.

Parameter Comparison

Engineering Selection Recommendations

The NGCMA50AX01A1B is the qualified substitute for the obsolete 91MCE16-P5 based on electrical and mechanical parameter equivalence. Both components are RoHS compliant and carry MSL 1 classification, meeting regulatory and environmental requirements.

The primary distinction between the two parts is product status: the 91MCE16-P5 is obsolete, while the NGCMA50AX01A1B is active. The NGCMA50AX01A1B features stainless steel roller construction and maintains all critical electrical specifications including 6A AC / 550mA DC current capacity, 120V AC / 125V DC voltage ratings, DPST-NO/NC circuit configuration, and IP67 environmental protection.

One operational parameter difference exists: the NGCMA50AX01A1B operates within a -25°C to 75°C temperature range, compared to the 91MCE16-P5 range of -25°C to 85°C. Applications requiring operation above 75°C require engineering evaluation to determine if this narrower range presents a constraint.

Both parts share identical electrical life (500,000 cycles) and mechanical life (5,000,000 cycles) ratings, ensuring equivalent reliability and durability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the NGCMA50AX01A1B directly replace the 91MCE16-P5 in existing applications?

A: Yes, the NGCMA50AX01A1B provides direct functional replacement for the 91MCE16-P5. Both components share identical circuit configuration (DPST-NO/NC), current ratings (6A AC / 550mA DC), voltage ratings (120V AC / 125V DC), actuator type (side rotary roller), mounting interface (chassis mount), termination style (cable leads), and environmental protection (IP67). Physical mounting and electrical connection compatibility are maintained.

Q: What is the significance of the operating temperature range difference?

A: The 91MCE16-P5 operates from -25°C to 85°C, while the NGCMA50AX01A1B operates from -25°C to 75°C. This 10°C difference in the upper temperature limit represents a narrower operating envelope for the substitute. Applications requiring sustained operation above 75°C should be evaluated against the substitute's specifications to confirm suitability.

Q: Why is the 91MCE16-P5 classified as obsolete?

A: The 91MCE16-P5 is classified as obsolete, indicating that Honeywell has discontinued production and support for this model. The NGCMA50AX01A1B, as an active product in the NGC series, represents the current manufacturing equivalent with ongoing availability and manufacturer support.

Q: Are there differences in mechanical characteristics between these parts?

A: Both parts maintain identical operating force (18gfm), electrical life (500,000 cycles), and mechanical life (5,000,000 cycles). The NGCMA50AX01A1B incorporates stainless steel roller construction. Minor differences exist in release force and travel specifications (pretravel, differential travel, overtravel), but these do not affect functional substitution for standard applications.

Q: What compliance certifications apply to both parts?

A: Both the 91MCE16-P5 and NGCMA50AX01A1B are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity classification. Both are classified under ECCN EAR99 and HTSUS 8536.50.9055, meeting regulatory and environmental standards for industrial switch applications.
