Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPDT
• Switch function: Mom-Off-Mom
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 85°C

Electrical Compatibility Criteria:

• Current rating must meet or exceed 0.4VA
• Voltage ratings (AC/DC) must meet or exceed 20V

Compliance Criteria:

• RoHS3 Compliant status
• Active product status

Two substitute parts meet these criteria with varying electrical performance levels:

Group 1 - Electrical Equivalent (0.4VA @ 20V): TE Connectivity ALCOSWITCH Switches 3-1825137-6 matches the original part's electrical specifications exactly while maintaining all mechanical and functional parameters.

Group 2 - Higher Electrical Rating (5A @ 120V AC / 28V DC): E-Switch 100SP4T6B11M2QEH provides enhanced electrical capacity while maintaining identical mechanical mounting and circuit configuration, suitable for applications requiring higher current or voltage margins.

Parameter Comparison

Engineering Selection Recommendations
