E22-50K Equivalent & Substitute Parts

Part Overview

The E22-50K is a snap action switch manufactured by ZF Electronics, configured as a single-pole double-throw (SPDT) device with on-momentary function. This chassis-mounted switch is rated for 3A AC at 125V and 100mA DC at 125V, featuring a lever roller actuator with quick connect termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance and repair applications where original stock is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the E22-50K is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must be On-Momentary to preserve operational behavior
• Voltage Rating: Must support minimum 125V AC and DC
• Mounting Type: Must be chassis mount for mechanical compatibility
• Actuator Type: Must feature lever and roller configuration
• Operating Temperature Range: Must encompass -40°C to 85°C minimum
• Termination Style: Quick connect terminals are preferred for compatibility, though mechanical adaptation may be required if terminal dimensions differ

The substitute part V7-1C17E9-207 (Honeywell Sensing and Productivity Solutions) meets all critical substitution criteria. This part exceeds the original specifications in current rating (15A AC vs. 3A AC) and electrical life (100,000 cycles vs. 6,000 cycles), providing enhanced performance margins for the same voltage and temperature operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The V7-1C17E9-207 is suitable as a direct functional substitute for the E22-50K based on the following criteria:

• Both parts maintain identical SPDT circuit configuration and on-momentary function
• Voltage ratings are equivalent at 125V AC and DC
• Operating temperature ranges are identical (-40°C to 85°C)
• Both parts feature lever roller actuators with chassis mount configuration
• The substitute part carries active product status with RoHS compliance, ensuring continued availability and regulatory alignment
• Current and electrical life ratings of the substitute exceed original specifications, providing operational margin without introducing incompatibility

The primary consideration is termination style compatibility. The E22-50K uses 0.187" (4.7mm) quick connect terminals, while the V7-1C17E9-207 uses 0.250" (6.3mm) quick connect terminals. Mechanical adaptation or terminal rework may be required depending on the host equipment design.

Frequently Asked Questions (FAQ)

Q: Can the V7-1C17E9-207 directly replace the E22-50K without modification?

A: Functional substitution is valid. However, the termination style differs (0.187" vs. 0.250" quick connect), requiring verification of connector compatibility in the target application. If the host equipment uses 0.187" connectors, terminal adaptation is necessary.

Q: Why does the substitute part have higher current ratings?

A: The V7-1C17E9-207 is rated for 15A AC and 500mA DC compared to the E22-50K's 3A AC and 100mA DC. This represents a design improvement in the Honeywell product line. Higher ratings do not create incompatibility; the substitute will function correctly in circuits designed for the lower-rated original part.

Q: Are both parts RoHS compliant?

A: Yes. The E22-50K is RoHS3 compliant, and the V7-1C17E9-207 is RoHS compliant. Both meet current environmental regulations.

Q: What is the significance of the electrical life difference?

A: The E22-50K is rated for 6,000 electrical cycles, while the V7-1C17E9-207 is rated for 100,000 cycles. The substitute provides extended operational life, which is advantageous for reliability but does not affect immediate compatibility.

Q: Are the mechanical dimensions compatible?

A: Both parts feature lever roller actuators with chassis mount configuration and operate within the same temperature range (-40°C to 85°C). Operating position and travel specifications are nearly identical (0.803" vs. 0.806" operating position), confirming mechanical compatibility for most applications.

Q: What packaging is available for the substitute?

A: The V7-1C17E9-207 is available in bulk packaging, compared to the original part's standard packaging designation.
