914CE18-3A Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The 914CE18-3A is an active-status snap action switch manufactured by Honeywell Sensing and Productivity Solutions. This SPDT (Single Pole Double Throw) switch is designed for chassis mount applications with cable lead termination and IP66 ingress protection. The switch operates at 5A AC / 3A DC with voltage ratings of 240V AC and 28V DC, featuring a round pin plunger actuator and on-momentary switch function.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and circuit configuration can be maintained within the allowed parameter tolerances for the application category.

Engineering Selection Recommendations

Primary Part (914CE18-3A):

Select when Honeywell component qualification is required
Active product status with 777 units in stock
RoHS compliant for regulated applications
IP66 ingress protection suitable for standard industrial environments

Substitute Part (D4C-1631):

Select when Omron component qualification is required or preferred
Active product status with 933 units in stock
ROHS3 compliant, meeting current regulatory requirements
Enhanced IP67 ingress protection for applications requiring waterproof sealing
Electrical ratings exceed primary part specifications across all parameters
Both parts carry EAR99 ECCN classification for export control purposes

Selection between these parts is determined by procurement requirements, supply chain preferences, and component qualification standards rather than electrical or mechanical performance limitations.

Frequently Asked Questions (FAQ)

Q: Can D4C-1631 directly replace 914CE18-3A in existing designs?

A: Yes. The D4C-1631 maintains equivalent SPDT circuit configuration, on-momentary switch function, identical mechanical dimensions (0.980" operating position), and equivalent pretravel/overtravel specifications. Current and voltage ratings of the D4C-1631 meet or exceed all 914CE18-3A specifications.

Q: What are the key differences between these switches?

A: The D4C-1631 provides higher current capacity (4A DC vs. 3A DC), higher voltage ratings (250V AC / 30V DC vs. 240V AC / 28V DC), superior ingress protection (IP67 vs. IP66), and lower operating force (1800gf vs. 2300gf). Both achieve identical mechanical life cycles and operating position specifications.

Q: Are there packaging differences?

A: The 914CE18-3A is supplied with cable length of 3 feet. The D4C-1631 is supplied with cable length of 3 meters. Verify cable length requirements for your application before substitution.

Q: Do both parts meet RoHS requirements?

A: Yes. The 914CE18-3A is RoHS Compliant. The D4C-1631 is ROHS3 Compliant, representing the current regulatory standard.

Q: What is the operating temperature range for each part?

A: The 914CE18-3A operates from 0°C to 105°C. The D4C-1631 operates from -10°C to 70°C. Verify operating temperature requirements for your specific application.

Q: Are both switches suitable for the same ingress protection requirements?

A: The 914CE18-3A provides IP66 (dust tight, water resistant) protection. The D4C-1631 provides IP67 (dust tight, waterproof) protection. The D4C-1631 offers enhanced environmental sealing for applications requiring waterproof operation.
