C&K 7105SYV3ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105SYV3ME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This part operates in a Mom-Off-Mom (momentary-off-momentary) switch function with a standard round actuator and PC pin termination. The 7105SYV3ME is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7105SYV3ME are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current rating (5A AC/DC minimum)
• Voltage ratings (120V AC / 28V DC minimum)
• Mounting type (Panel Mount)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

Parts meeting these criteria are classified as direct substitutes. Parts with reduced electrical ratings or different mechanical specifications are classified as similar substitutes with noted limitations.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105SYV3SE is the primary direct substitute for the obsolete 7105SYV3ME. Both parts are from the C&K 7000 series and share identical electrical ratings, mechanical dimensions, and functional specifications. The 7105SYV3SE carries Active product status and maintains full compatibility with applications designed for the 7105SYV3ME. RoHS compliance is maintained, though the 7105SYV3SE is REACH Affected compared to the REACH Unaffected status of the original part.

The E-Switch 100SP4T3B1VS2REH is classified as a similar substitute with electrical limitations. This part has reduced current and voltage ratings (0.4VA at 20V AC/DC versus 5A at 120V AC/28V DC). The actuator length differs at 13.97mm compared to 10.67mm. This substitute is suitable only for applications with lower power requirements and should not be used in circuits requiring the full electrical specifications of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 7105SYV3SE directly replace the 7105SYV3ME in existing designs?

A: Yes. The 7105SYV3SE maintains identical electrical ratings (5A at 120V AC/28V DC), circuit configuration (SPDT), switch function (Mom-Off-Mom), and mechanical specifications including panel cutout dimensions and bushing thread. The part is mechanically and electrically interchangeable.

Q: What are the key differences between the 7105SYV3SE and the original 7105SYV3ME?

A: The primary difference is product status: the 7105SYV3ME is obsolete while the 7105SYV3SE is active. The 7105SYV3SE is REACH Affected, whereas the original is REACH Unaffected. All electrical and mechanical parameters remain identical.

Q: Is the E-Switch 100SP4T3B1VS2REH a suitable replacement?

A: The 100SP4T3B1VS2REH is a similar substitute only for applications with reduced power requirements. It has significantly lower current (0.4VA) and voltage ratings (20V AC/DC) compared to the 5A at 120V AC/28V DC specification of the 7105SYV3ME. The actuator length is also longer at 13.97mm. This part is not suitable for applications requiring the full electrical specifications of the original part.

Q: What panel cutout dimensions are required for installation?

A: All substitute parts maintain the same panel cutout specification: Circular - 6.35mm Dia with 1/4-40 bushing thread. Panel modifications are not required when substituting between these parts.

Q: Are there any compliance considerations when substituting parts?

A: Both the 7105SYV3SE and 100SP4T3B1VS2REH are ROHS3 compliant. The 7105SYV3SE is REACH Affected, while the original 7105SYV3ME is REACH Unaffected. Verify REACH compliance requirements for your specific application and region before final part selection.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts maintain the same operating temperature range of -30°C to 85°C. Thermal performance is equivalent across all listed substitutes.
