Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91MCE16-PBQ is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration must be DPST-NO/NC
• Current rating must support minimum 6A AC and 550mA DC
• Voltage ratings must meet or exceed 120V AC and 125V DC

Mechanical & Physical Equivalence Requirements:

• Actuator type must be side rotary with roller mechanism
• Mounting configuration must be chassis mount
• Termination style must be connector-based
• Ingress protection must maintain IP67 rating

Functional Equivalence Requirements:

• Switch function must support On-Mom, Off-Mom operation
• Electrical life must meet or exceed 500,000 cycles
• Mechanical life must meet or exceed 5,000,000 cycles

Compliance Requirements:

• RoHS compliance status must be maintained
• Moisture sensitivity level must be MSL 1 or equivalent

Substitute parts must satisfy all criteria within these categories to ensure direct functional and mechanical compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

The NGCMB00NX01A1B qualifies as a direct substitute for the obsolete 91MCE16-PBQ based on electrical, mechanical, and functional parameter equivalence. Both components are manufactured by Honeywell Sensing and Productivity Solutions and maintain identical circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style.

The NGCMB00NX01A1B is classified as an active product, ensuring ongoing availability and supply chain support compared to the obsolete 91MCE16-PBQ. Both components maintain RoHS compliance and identical moisture sensitivity classification, satisfying regulatory and environmental requirements.

A minor operational difference exists in the upper operating temperature limit: the 91MCE16-PBQ operates to 85°C while the NGCMB00NX01A1B operates to 75°C. Applications requiring operation above 75°C must evaluate this parameter against specific system requirements. All other mechanical and electrical parameters remain equivalent or exceed the original specification.

Frequently Asked Questions (FAQ)

Q: Can the NGCMB00NX01A1B directly replace the 91MCE16-PBQ without design modification?

A: Yes. 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 type (chassis mount), termination style (connector), and ingress protection (IP67). No design modification is required for electrical or mechanical integration.

Q: What is the significance of the product status difference between these parts?

A: The 91MCE16-PBQ is classified as obsolete, indicating discontinued manufacturing and limited availability. The NGCMB00NX01A1B is classified as active, confirming current production and reliable supply chain access. For new designs or ongoing production requirements, the active substitute is the appropriate selection.

Q: Are there any operational differences between these switches?

A: The primary operational difference is the upper temperature limit. The 91MCE16-PBQ operates from -25°C to 85°C, while the NGCMB00NX01A1B operates from -25°C to 75°C. Applications requiring sustained operation above 75°C must verify compatibility with the substitute part's temperature specification. All other operational parameters, including electrical life (500,000 cycles) and mechanical life (5,000,000 cycles), are identical.

Q: Do both components meet the same regulatory and compliance standards?

A: Yes. Both the 91MCE16-PBQ and NGCMB00NX01A1B are RoHS compliant, classified as MSL 1 (unlimited moisture sensitivity level), and assigned the same ECCN (EAR99) and HTSUS code (8536.50.9055). Regulatory and environmental compliance requirements are satisfied by either component.

Q: What connector type is used for termination on both switches?

A: Both components utilize connector-based termination. The specific connector type and pin configuration are not provided in the available technical parameters. Verification of connector compatibility with existing harnesses or PCB interfaces is required during integration planning.

Q: Is the NGCMB00NX01A1B available in the same packaging as the 91MCE16-PBQ?

A: Packaging information is not specified in the available technical parameters for either component. Contact the manufacturer or authorized distributor to confirm packaging compatibility and any differences in physical dimensions or protective materials.
