E22-00K Equivalent & Substitute Parts

Part Overview

The E22-00K is a snap action switch manufactured by ZF Electronics, configured as a single-pole double-throw (SPDT) device with on-momentary switch 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, repair, and system continuity applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the E22-00K is determined by the following critical parameters:

Core Functional Requirements:

• Circuit configuration must remain SPDT
• Switch function must be on-momentary
• Mounting type must be chassis mount
• Actuator type must be lever with roller mechanism
• Operating temperature range must encompass -40°C to 85°C

Electrical Compatibility Criteria:

• AC voltage rating must be ≥125V
• DC voltage rating must be ≥125V
• AC current rating must be ≥3A
• DC current rating must be ≥100mA

Mechanical & Interface Compatibility:

• Termination style must be quick connect format
• Operating position must be within acceptable mechanical envelope
• Pretravel and differential travel must be compatible with system design

The substitute part V7-1C17E9-207 meets all core functional requirements and exceeds electrical ratings, providing enhanced performance characteristics while maintaining mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The V7-1C17E9-207 manufactured by Honeywell Sensing and Productivity Solutions is a qualified substitute for the obsolete E22-00K. Selection is supported by the following factors:

Compliance & Regulatory Status:

• Both parts maintain RoHS compliance, satisfying environmental and regulatory requirements
• Both parts are classified under identical HTSUS and ECCN codes, confirming equivalent product classification

Electrical Performance:

• The substitute part exceeds the electrical requirements of the original specification, providing 15A AC capacity versus the required 3A, and 500mA DC capacity versus the required 100mA
• Voltage ratings remain identical at 125V AC and DC

Mechanical Compatibility:

• Chassis mount configuration, lever roller actuator, and on-momentary function are preserved
• Operating temperature range is identical
• Operating position differential of 0.003" (0.1mm) is negligible for mechanical envelope considerations

Critical Consideration:

• Termination connector size differs: E22-00K uses 0.187" (4.7mm) quick connect, while V7-1C17E9-207 uses 0.250" (6.3mm) quick connect
• This difference requires mechanical interface verification and potential harness modification during installation

Operational Enhancement:

• The substitute part provides 100,000 electrical cycles versus 6,000 cycles for the original, extending service life and reducing replacement frequency

Frequently Asked Questions (FAQ)

Q: Can the V7-1C17E9-207 directly replace the E22-00K without modification?

A: Functional substitution is confirmed for circuit operation and electrical performance. However, the quick connect termination size differs (0.187" versus 0.250"), requiring mechanical interface assessment. Connector compatibility must be verified before installation.

Q: What are the key differences in mechanical operation between these parts?

A: The V7-1C17E9-207 exhibits greater pretravel (0.112" versus 0.047"), differential travel (0.025" versus 0.010"), and overtravel (0.065" versus 0.040"). These differences may affect actuation feel and system response characteristics. System-level testing is appropriate when mechanical precision is critical.

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

A: The V7-1C17E9-207 is designed for higher-power applications, providing 15A AC and 500mA DC capacity. When used in the E22-00K application requiring only 3A AC and 100mA DC, the substitute operates well within its design envelope, providing operational margin and extended component life.

Q: Are both parts environmentally compliant?

A: Yes. The E22-00K is RoHS3 compliant, and the V7-1C17E9-207 is RoHS compliant. Both parts satisfy current environmental and regulatory requirements for electronic component use.

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

A: The E22-00K is rated for 6,000 electrical cycles, while the V7-1C17E9-207 is rated for 100,000 cycles. This represents approximately 16.7 times greater operational life, reducing maintenance frequency and improving system reliability in applications with frequent switching cycles.

Q: How do I determine if the connector size difference will affect my installation?

A: The quick connect termination size difference requires physical verification of your existing harness and connector receptacles. If your system uses 0.187" (4.7mm) connectors, harness modification or adapter solutions will be necessary. Consult your system documentation or contact your connector supplier for compatibility assessment.
